Title: Improvements in or relating to infra-red gas analysing apparatus
Filed: 1948-10-06
Abstract: <PICT:0645575/III/1> In a gas analyser of the type wherein infrared radiation is passed through a pair of gas-filled tubes, one of which contains the test-sample, into a pair of detecting chambers C, Cl separated by a metal diaphragm D and filled with the gaseous constituent to be estimated, such that absorption of a particular infra-red band by the constituent to be detected in the test-sample tube gives rise to a difference in the absorption and therefore temperature and pressure in chambers C, Cl, whereupon the diaphragm deforms and gives rise to capacity changes in relation to an insulated perforated plate E, the single test-sample tube usually employed is replaced by a plurality of axiallyaligned tubes B1, B2, B3 of varying length, the tube of a length appropriate to the concentration range of the constituent to be estimated in the sample gas being used to contain the test-sample and the others being filled with a standard or filter gas.  The capacity changes are amplified electronically and measured on a meter calibrated in gas concentration.  A rotating shutter F interrupts the radiation and gives rise to pressure pulses in the detecting chambers.

Filed: 1951-11-15
Abstract: 692,765. Glass-metal seals. PHILIPS ELECTRICAL INDUSTRIES, Ltd. Nov. 15, 1951 [Nov. 18, 1950], No. 26771/51. Class 36. [Also in Group XL (a)] To seal a glass window to the iron cone of a cathode-ray tube, a nickel layer is applied to the iron, at least in the-sealing zone, and at least this zone is degasified in an oxidizing atmosphere, whereupon the window is sealed to the cone and then cooled to mitigate strain. The nickel layer is less than 20 Á thick, and it may be thicker at the sealing zone than over the rest of the cone. The sealing zone may additionally be coated with a layer of chromium, also less than 20 Á thick, preferably 3 Á. The degasifying is carried out by heating in an oxidizing flame for 3 minutes at 950-1000‹ C., and this converts some of the nickel, and chromium if present, into oxide, as well as degasifying these layers and the underlying iron. The cone is then cooled to a temperature at which it will not damage the window, and the two are brought into contact. The window may be pre-heated if necessary. The temperature of the glass is raised and sealing takes place at 900-950‹ C., after which the assembly is cooled.

Abstract: 1497738 Sequentially accessed stores FUJITSU Ltd 24 June 1975 [24 June 1974] 26834/75 Heading G4C  Data is written into one of a series of sequentially connected data storage stages SQ1 . . . SQn (Fig. 1) by transferring to an auxiliary memory M the data in each stage preceding the selected stage, transferring the new data to stage SQ1 and shifting it along the stages, followed by the data originally transferred to the auxiliary memory, the data in subsequent stages not being affected. As described "1" signals on write line W (Fig. 2) and line SQSL result in the address of the selected stage SQj being entered from bus DB into bistables FF. A gate decoder GSL then applies a "1" signal on the write lines W 1  ... Wj to enable read out of their contents to the data bus DB. For a read operation a "1" signal exists on line W to permit setting in the bistables FF of the address of the stage to be read. A read signal R results in a signal on only the read line of the selected stage SQj so that subsequent data on the bus DB is read into the stage. The apparatus may be incorporated into a microprogrammed processing system in which the address data from two sequentially used control stores (CS1, CS2, Fig. 6, not shown) is fed to a chain of address registers (AR3-AR5) from which it may be fed to address registers (AR1, AR2) associated with the stores either from a first stage (AR3) or, if retry is necessary from the last stage (AR5).

Abstract: A process for producing a polyurethane polyisocyanate film-forming composition suitable for use as a patent leather finish comprises first producing a polyurethane polyol reaction product by heating a mixture of castor oil and organic diisocyanate in such proportions that the ratio of NCO groups to OH groups in the reactants is between 0,4 and 0,6 until the viscosity of the reaction mass has risen to a maximum value which remains substantially unchanged on further heating, and then heating the polyurethane polyol reaction product with additional organic diisocyanate in such an amount that the NCO/OH ratio of the polyurethane polyol-organic diisocyanate mixture is at least 2,0, until the measured amine equivalent of the product differs by not more than 10% from the theoretical amine equivalent. Preferably an NCO/OH ratio of 2,2 or 2,3 is employed in the second stage.  By "amine equivalent" is meant the weight of a portion of the batch which contains one equivalent weight of isocyanate.  In an example the NCO/OH ratios, using tolylene 2,4- and 2,6-diisocyanates, in the first and second stages were 0,5 and 2,23 respectively. Toluene, xylene, petroleum hydrocarbons, isopropyl ether, ethyl acetate, methyl ethyl ketone and cyclohexanone are suitable solvents for the products.  In a test a film of material was prepared by casting on a mercury surface.  As catalysts for the film forming reaction dibutyl tin dilaurate, methyl diethanolamine, dimethyl ethanolamine, triethylenediamine, N-methyl morpholine, diethylcyclohexylamine, the adipic acid diester of diethylaminoethanol, and soluble lead and cobalt salts are specified.
