Reference excerpt

Kolster-Brandes Ltd was a British manufacturer of radio and television sets based in Foots Cray, Sidcup, Kent that was American owned.

History The company was a descendant of Brandes, a Canadian company founded in Toronto in 1908. Brandes became part of AT&T in 1922 and a British subsidiary Brandes Ltd was established in Slough, in 1924, to manufacture headphones. The company rapidly expanded producing a range of loud speakers and in 1928 moved to a former silk mill at Foots Cray. The company was renamed Kolster-Brandes Ltd after the American parent company merged with the Kolster Radio Corporation. In 1930 the company supplied 40,000 of its Masterpiece two-valve, bakelite cabinet radios to the Godfrey Phillips tobacco company, who gave them away to customers in exchange for cigarette coupons. K-B also began a long association with Cunard after they won a contract to provide communications equipment for the RMS Queen Mary ocean liner. In 1938 Kolster-Brandes became part of ITT's British subsidiary Standard Telephones and Cables (STC). The Foots Cray site was also shared by Brimar, another STC company founded in 1933 to manufacture American pattern valves for the British market. In 1960/61 STC took over Ace, Argosy, Regentone and RGD, and then in 1968 the Kolster-Brandes logo name changed to ITT KB, and between 1973 and 1974 the KB was dropped from the logo and sets were only made under the ITT label.

Products Kolster-Brandes later went on to make mid-range electronics such as radios, radiograms, televisions, tape recorders, amplifiers and gramophones. KB made a large number of radios and radiograms, a few models of which were the 285, 422 Cavalcade, 666 and the CG20. The company also made a popular selection of record players which include the Playtime, Gaytime, Dancetime, Tunetime and Rhythm, the last two of which are valve operated.

Worked examples

Example 1 — a first encounter with Kolster-Brandes

Start with the simplest possible case. Write down what Kolster-Brandes claims or describes in one sentence, then invent the smallest concrete situation in which that sentence is true. In science, the smallest case is usually a single object, a single equation or a single measurement. Check that every symbol or term in your sentence has a meaning in that case.

Example 2 — changing one variable

Take the situation from Example 1 and change exactly one quantity: double it, halve it, or set it to zero. Predict what should happen to Kolster-Brandes before you calculate. Comparing your prediction with the result is the fastest way to find out whether you understand the idea or only the words.

Example 3 — an exam-style question

Typical questions about Kolster-Brandes ask you to (a) state it precisely, (b) apply it to given data, and (c) explain a limitation. Practise writing all three answers in under five minutes; the third part is what separates a full-mark answer from an average one.

Applications of Kolster-Brandes

In research: Kolster-Brandes appears in science research whenever the underlying quantities have to be modelled precisely. Papers usually cite it as a starting assumption and then explore where it breaks down.
In technology and industry: Engineering practice reuses Kolster-Brandes in design rules, simulations and safety margins. Knowing the idea lets you read a specification sheet and understand why the numbers look the way they do.
In the classroom: Kolster-Brandes is common in secondary-school and first-year university syllabi. It links to neighbouring topics Defunct manufacturing companies of the United Kingdom, Electronics companies of the United Kingdom, Radio manufacturers, so understanding it makes those chapters shorter.
In everyday life: Look for Kolster-Brandes outside the textbook — in sport, cooking, traffic, electronics or the sky above you. An example you found yourself is remembered far longer than one you were given.
