Filed: 1927-07-22
Abstract: 299,097. Schnabel, R., and Excelsior Feuerl÷schgerõte, Akt.-Ges. July 22, 1927. Chemicals; fire-extinguishing by foam; portable pressure reservoirs.-A method of producing foam consists in super-saturating with carbon dioxide or other gas under pressure a foam-generating liquid, such as saponin solution, in a closed container, and sealing the container. When the seal, for example, a cock, is opened the effervescence of the liberated gas produces the foam which is discharged from the container. Soluble or insoluble substances may be added to the foam generator to assist in the absorption or liberation of the gas.

Title: Improvements relating to Matrix Stores
Inventor: SINDEN KENNETH HARRY
IPC: G11C17/00
Filed: 1965-05-11
Abstract: 1,150,592. Matrix storage apparatus. ELECTRIC & MUSICAL INDUSTRIES Ltd. 2 May, 1966 [11 May, 1965], No. 19765/65. Heading H3B. The time between the start of an address of a storage element in a matrix and the appearance of an output signal in a reading circuit is made the same for all positions in the matrix. In order to select an element of the uniaxial anisotropic thin film matrix shown a negative signal is applied to one of the conductors X1, X2 ... X32 to turn off the associated transistor TX, which transistors are normally conducting. The resulting positive pulse set up at the collector of the associated transistor TX is transmitted down the corresponding one of the conductors C1, C2 ... C32 from which it is applied to the bases of sixty-four of the transistors T. A Y selection signal is applied to one of the terminals Y1, Y2 ... Y64 from which it is applied to the base of a corresponding transistor TY to cause it to conduct. Connected to the collector of each of the transistors TY is a respective group of thirty-two transistors T and since one transistor in each of the sixty-four groups of transistors T is connected to the selected one of the conductors C only one of the transistors T produces a current pulse in the drive conductor D connected to its collector electrode. In order to compensate for the delay of the signals due to the lengths of the drive conductors DD, D and the sense conductors S which delay is not constant but is dependent on which element is selected, the conductors C are substantially co-extensive with the conductors DD and S. This results in the time delay between the application of a signal to the selected one of the terminals X1, X2 ... X32 and the appearance of a drive signal on the selected one of the drive conductors D being substantially equal to the time delay imposed by the conductors DD on the digit drive signals and is complementary with the time delay between the application of the drive signal to the selected conductor D and the appearance of the corresponding output signals at the amplifiers A. The Y signal is made of longer duration than the X signal to accommodate the spread in time of arrival of the voltage pulses from the transistors TX at the bases of the transistors T. A strobing signal for selecting only that part of the output signals which represents the stored digits may be derived from the X-signal to appear at a constant instant of time thereafter. The collector loads B of the transistors TX and the loads L of the conductors C are chosen to be equal to the characteristic impedance of the lines C. The input capacities of the transistors T form part of the delay lines comprising the conductors C. The invention may be applied to super-conductive stores.

Abstract: 1513753 Valves ROBERT BOSCH GmbH 13 May 1975 [27 Aug 1974] 19999/75 Heading F2V [Also in Division F1]. A valve 6 in a fuel-injection system comprises a diaphragm 5 carrying a closure plate 13 to co-operate with a seat 8, the periphery of the plate engaging a knife-edge ring 44 when the valve is closed.

Filed: 1972-04-29
Abstract: 1442322 Cutlery RADMORE & CO Ltd 18 July 1973 [29 April 1972] 20019/72 Heading A4A [Also in Division B4] A pair of cutlery utensils 10, 11 able to be used as a server in the manner of tongs are releasably coupled at their handle ends by the engagement of a necked projection 15 on one with a hole 13 in the other. Preferably the length of a T head projection 14, 15 is less than that of the hole whilst it is greater than the width thereof. Engagement is effected by passing the T head through the hole when the former is aligned with the length of the latter and retaining it by subsequent rotation through 90 degrees relative to the latter. The rectangular hole is slightly tapered narrowing away from the end of the handle to a dimension less than the width of the neck 15 which is thus prevented from moving any appreciable distance away from the handle end when the two utensils are coupled. The utensils are made from stainless steel and are sufficiently resilient to allow their handles to flex in their mid regions so that food may be gripped between their operative ends. Each handle has a non-metallic grip 12 riveted to it. One longitudinal edge of each utensil is straight in plan view and as a result they may be produced from sheet material with minimum waste by pressing from blanks with their straight edges adjacent to one another.
