Viscount Model Rolls razor in simulated leather case circa s. It seems that no one could bear to throw away a Rolls Razor. That must be why there are so many of these British made safety razors still around. There were 25 for sale on the eBay auction the last time we checked. These razors are sometimes described as made by the Rolls-Royce company. Not so, but the name was undoubtedly chosen to evoke the “Rolls” image of luxury and quality. The Rolls “The Whetter” trademark was registered in the U. The name “Rolls Razor Ltd.

Gillette Date Codes “How old is this razor? Sometimes patent dates are a help, but they give you the front end of the date scale, and not always too exactly. Some razor makers put serial numbers on their razors, but we don’t always have the key to how the serial numbers fit to dates of manufacture. Gillette is one manufacturer for whom we have information on serial numbers and later date of manufacture codes that we can link to time.

Other makers included serial or manufacturing codes, but we do not have the keys.

The number of Office actions and responses that may occur vary from country to country, but eventually a final rejection is sent by the patent office, or the patent application is granted, which after the payment of additional fees, leads to an issued, enforceable patent.

History of Technology Heroes and Villains – A little light reading Here you will find a brief history of technology. Initially inspired by the development of batteries, it covers technology in general and includes some interesting little known, or long forgotten, facts as well as a few myths about the development of technology, the science behind it, the context in which it occurred and the deeds of the many personalities, eccentrics and charlatans involved.

You may find the Search Engine , the Technology Timeline or the Hall of Fame quicker if you are looking for something or somebody in particular. Scroll down and see what treasures you can discover. Background We think of a battery today as a source of portable power, but it is no exaggeration to say that the battery is one of the most important inventions in the history of mankind. Volta’s pile was at first a technical curiosity but this new electrochemical phenomenon very quickly opened the door to new branches of both physics and chemistry and a myriad of discoveries, inventions and applications.

The electronics, computers and communications industries, power engineering and much of the chemical industry of today were founded on discoveries made possible by the battery. Pioneers It is often overlooked that throughout the nineteenth century, most of the electrical experimenters, inventors and engineers who made these advances possible had to make their own batteries before they could start their investigations. They did not have the benefit of cheap, off the shelf, mass produced batteries.

For many years the telegraph, and later the telephone, industries were the only consumers of batteries in modest volumes and it wasn’t until the twentieth century that new applications created the demand that made the battery a commodity item. In recent years batteries have changed out of all recognition. No longer are they simple electrochemical cells.

This included Darrow’s inventory of game parts. PB immediately began selling Monopoly games using the Darrow game parts. About 24, – 25, of these were maunfactured. This included a small number of the No 9 long box, very rare today. Over , games were produced with this label. This statement was used for a while in , but they discovered that there were other games very much like Monopoly already with patents.

European Patents – The Basics This is information is also available in Japanese , Chinese and Korean Historically, to obtain a patent in a country you had to apply to the patent office in that country. If patent protection across Europe was wanted, separate applications were needed for each country. Since , however, it has been possible to file a European patent application to obtain a European patent which may take effect in a number of countries.

What is a European patent? A European patent can be an easier and cheaper alternative to obtaining individual national patents in the countries which are members of the European Patent Convention EPC. A list of these member countries is attached.

Lighters made before had the earlier patent number and it is the placement of this number, along with the placement of the word “ZIPPO” that can help identify the date. Some important points to note are the shape of the “3” within this patent number, some lighters have a round top 3 whilst other have a flat top.

US universities remain the most prolific international patent filers among higher education institutions worldwide, accounting for 30 of the top 50 institutions. Israel has two universities in the top 50, and Australia, China, Denmark and Singapore have one each. America also led the top 15 countries in filing international patent applications, followed by Japan and Germany.

First and foremost is the public support for research-intensive universities, dating from the land grant college act under President Abraham Lincoln, which created centres for agricultural technology in universities. For example, the NSF has long provided grants to university-industry partnerships that develop technology. Importantly, the Bayh-Dole Act of allowed universities to patent inventions arising out of government funding.


This gave me pause to think about all kinds of numbers, found on flat- and hollowware. Most collectors are familiar with termini technici like scratch weight, British registration mark, etc. An article giving more info about all these numbers seemed like a good idea.

Product Dating Find out exactly when your instrument or amplifier was manufactured.

World’s Largest Selection of Wicks! Very unique lamp designs intended for sale in the UK sometimes had design numbers. The following metalware information was formerly available on the Oxton Decorative Arts web site: This was a system which came into being in and started to decline in the early s. It enabled manufacturers, retailers or designers to register their designs, so that they could not be copied.

It was therefore like a cross between a patent and a copyright. Many designs were registered by the manufacturers or retailers rather than the designers, so it is not often possible to identify designers on the basis of Registered Design numbers alone. The letter at the top corner identifies the year. This system ran until , when it was replaced by a series of sequential numbers preceded by Rd, which can be banded into years for dating purposes. For example, Rd dates a design to

By Eric Waltmire on March 21, in Patent Published patent applications look similar to granted patents. So it is not unusual for a published patent application to be mistaken for a granted patent. Not every patent application results in a granted patent. The following image is an excerpt from the front page of granted US Patent No. The following image is an excerpt of the front page of the Patent Application Publication No.

THE RIFLE. The design of the Lee-Enfield Rifle No.8 was the outcome of much research and trialling immediately after the War. At least two prototypes .

As a leader in the unfolding intellectual, social, political, and economic revolutions of eighteenth and nineteenth century Europe, Britain had a long history of extending formal protection to ideas and products. A textbook example of early industrial capitalism was the nineteenth century British pottery industry. While the early focus of protection was on technique and product, after , English potters could also register their designs or patterns with the Patent Office and then impress or print the registry designation upon a vessel.

Doing so likely served at least two functions. First, it provided the producer with some design protection even though English potters were notorious in their “adaptations” of the patterns of others. Secondly, it served as a positive marketing device to the extent that consumers viewed English pottery as a superior product. However, these two functions were apparently not overly significant because the vast, vast majority of pottery coming out of England lacked registry designation marking.

Nonetheless, when a basal sherd displaying a mark is recovered from an archaeological context, we can establish a reasonable dating floor for the vessel.

Premises were needed for the new organisation. Marconi decided upon a place that was a relatively short distance from London and accessible by rail; Chelmsford was an ideal location. In December , the first wireless factory in the world was set up in an old silk factory in Hall Street. The building still stands today. The Wireless Telegraph and Signal Company changed names several times to: In GEC was renamed Marconi plc.

The first life-saving possibilities of wireless were realised in when a wireless message was received from the East Goodwin lightship – which had been equipped with Marconi wireless apparatus. It had been rammed in dense fog by a steamship R. A request was made for the assistance of a lifeboat.
