Patent GB-1402444-A (GB)
Title: Semiconductor memory
IPC: G11C11/402
Filed: 1972-07-13
Abstract: 1402444 Matrix store addressing circuits ADVANCED MEMORY SYSTEMS Inc 13 July 1972 [24 Feb 1972] 32859/72 Heading G4C [Also in Division H3] A rectangular matrix store having column and row address lines is addressed by address decoders comprising a number of insulated gate field effect transistors (IGFET) and is fed with true and inverse address bits from IGFET inverters. The inverters act as storage registers and permit a new address to be passed to the addressing circuitry while the previously selected address is being accessed. The store disclosed is formed of 32 x 32 cells each comprising cross-coupled IGFETs (Fig. 7, not shown), a required cell being accessed by applying two 5-bit addresses to the addressing circuitry. This circuitry includes the circuits shown in Figs. 3-5. When a signal RESET, Fig. 2a, and a clock signal, Fig. 2b, are applied at 30, 32, Fig. 3, a signal RESET, Fig. 2c, appears at 34. Signals RESET and RESET are applied to each of two groups of five inverters, each as in Fig. 4, to which are also applied a respective address bit ADDRESS, Fig. 2d. Each inverter provides the true and inverse of the address bit at 54, 56. The states assumed by Q8, Q9 in response to the ADDRESS bit when RESET is high are maintained capacitively until RESET becomes low at T4. The ADDRESS bit need be present only for the duration T1-T2 of RESET and so the address bit at 52 may be changed to its next value at any time after T2. Thirty-two NAND gates, each as in Fig. 5, are coupled to each group of inverters. Each NAND gate has its inputs 62-70 coupled to appropriate ones of the true and inverse address bit outputs from the inverters of the respective group, and also receives the RESET signal. When an address pertinent to a particular gate is present line 72 is isolated from positive source Vss. Prior to time T1 signal RESET is low so that Q17 conducts. Since Vdd is negative Q18 conducts and consequently so does Q19. When RESET becomes high at T1, Q17 turns off. The address bits now applied to 62-70 cause all 31 gates except one in each group to connect line 72 to Vss so that Q19 turns off. For those 31 gates the signal at output terminal 60 will remain high, due to the construction of Q19 which exhibits enhanced gate-drain capacitance, shown as C2. For the remaining gate in each group Q19 remains on so that the signal at 60, which is fed to the appropriate row or column address line of the matrix, follows the clock signal, as shown in Figs. 2b, 2g.

IPC: C08F8/30
Filed: 1965-08-06
Abstract: Coloured copolymers are produced by reacting a copolymer of (a) an ethylenically unsaturated monomer which is capable of coupling and (b) an ethylenically unsaturated monomer which is incapable of coupling with an aqueous solution of a diazonium salt.  Monomer (a) may be 3-acryloylaminophenol, 3 - acryloyl - 4 - methylphenol, 1 - dimethylamino - 3 - acryloylaminobenzene, N - ethyl - N - vinyloxyethylaniline, 1 - acryloyl - 5 - hydroxynaphthalene, 1 - acryloylamino - 7 - hydroxynaphthalene, 2 - acryloylamino - 5 - hydroxy - 7 - sulphonaphthalene, 2 - vinylsulphonyl - 7 - hydroxynaphthalene, 1-phenyl - 31 - acryloylaminopyrazolone - 5 or 1 - phenyl - 41 - acryloylaminopyrazolone - 5, or the corresponding methacryloyl derivatives of said acryloyl compounds.  These monomers may be substituted with e.g. halogen atoms or alkyl, alkoxy, carboxy, acyl, acyloxy, hydroxyl, carbonyl, carboxylic, sulphonic, nitro or cyano groups.  Specified (b) monomers are styrene, butadiene, isoprene, acrylic, methacrylic and maleic acids, esters of said acids and alcohols containing 1 to 6 carbon atoms, vinyl acetate, vinyl propionate, vinyl chloride, vinylidene, chloride, vinyl methyl ether, acrylonitrile, methacrylonitrile, N-vinyl pyrrolidone, maleic anhydride, vinylsulphonic acid, N-vinyl imidazole and N-vinylimidazolium methyl sulphate. The copolymer is prepared conventionally and then dissolved or dispersed in an aqueous medium or an organic solvent prior to reaction with the diazonium salt solution, which may be derived from aromatic amines such as aniline, the anisidines, toluidines, xylidines, haloanilines, nitroanilines, sulphanilic acids and anthranilic acids and analogous compounds of the 1-naphthylamine, 2-naphthylamine, 2-aminothiazole, 2-aminothiodiazole-(1,3,4), 3-aminotriazole - (1,2,4) and the aminobenzothiazole series. Diamino compounds are used to prepare bisazonium salts which effect cross-linking of the copolymer.  The copolymers may also be cross-linked by incorporating (meth)acrylamide, N-methylol (meth)acrylamide or C1-C6 alkyl ethers of said methylol compounds, acrolein or allyl alcohol in the monomer mixture and then raising the pH of or heating the copolymer. Alternatively, aminoplast precondensates, dimethylol butanediol diurethane, formaldehyde, epoxy compounds or di- or polyisocyanates are added to the copolymer containing said cross-linking monomers. Ester or anhydride groups in the copolymer may be hydrolysed prior to cross-linking.  In the example, (a) 3-acryloylaminophenol and (b) ethyl acrylate are polymerized with the N-butyl ether of N-methylol methacrylamide in an n-butyl acetate/ethylene glycol monomethyl ether solution using azobisisobutyronitrile as catalyst. The polymer is precipitated with ethyl acetate and dissolved in water.  NaOH is added to the solution prior to reaction with diazotized 1-aminonaphthalene-4-sulphonic acid.

Abstract: 619,086. Screw conveyers. DEHN, S. G. (Minneapolis-Moline Power Implement Co.). Nov. 18; 1946, No. 34144. [Class 78 (i)] In a crop conveyer mechanism in which a rotary auger receives the crop material along one side and moves it longitudinally through a housing in co-operation with a stationary stripper plate, the stripper plate is angularly positioned with respect to the axis of the auger while extending edgewise towards the auger. A rotary auger 10 in the form of a tube 20 with a spiral or helical flight 21 receives the crop from a conveyer 11 and moves it longitudinally through a housing 14 in co-operation with a stationary stripper plate 23, set at an angle to the flight, to a feed opening 12 leading to a baler 13. The stripper plate is attached to one part of the housing 14 of the auger and is set at an angle thereto so that it crosses the flight of the auger at an angle D which is approximately a right angle. It is partly helical and twisted in a direction opposite to the direction of the vane of the auger. The stripper plate extends at a constant distance from the flight from a point substantially below the axis level of the inlet end to the auger, and thence upwardly around and along the upwardly moving side to a point above the axis level at the delivery end. When used with a longer auger, the inclination of the stripper plate is reduced so that the angle D is smaller.

Abstract: 506,680. Launching aircraft. GENERAL AIRCRAFT, Ltd., WILLIAMS, D. L. H., and CROCOMBE, F. F. Dec. 9, 1937, No. 34149. [Class 4] In an aircraft provided with nose and main landing elements disposed, respectively, forwardly and rearwardly of the centre of gravity of the aircraft, an accelerating force from a source of power external to the aircraft is applied to the aircraft, in such manner as to produce a pitching moment tending to load the nose landing-gear. As shown, an aeroplane having outboard engines includes a nose wheel supported on a shock-absorber and capable of either or both castoring and orientation for steering. The accelerating force is transmitted through a cable 12 which is detachably' connected to a hook 13 slidable against the action of a spring 17 in the aircraft structure. A, cable 24 connects the hook to a hook 20 normally held closed by a spring and engaging a retaining cable 18. The force is generated by, e:g. a piston-and-cylinder device operated by fluid pressure which may be generated by an explosive cartridge or by a winding mechanism. Tensioning the cable 12 compresses solid the spring 17 and through the cable 24 releases the hook 20. The hook 20 may have a manual release operable by the pilot. A guided trolley may be interposed in the cable 12.
