Filed: 1970-12-02
Abstract: 1328999 Quinacridones FARBWERKE HOECHST AG 2 Dec 1970 [4 Dec 1969 (2)] 57263/70 Heading C4P The invention comprises linear transquinacridones of the general formula wherein R is H or alkyl, e.g. C 1 -C 6  alkyl. They are prepared by treating a 2,5-diarylaminoterephthalic acid or C 1 -C 4  alkyl ester thereof with a ring closing agent at elevated temperature. The ring closing agents include sulphuric acid of 88% to 95% conc., boric acid, a metal halide, e.g. aluminium chloride, and polyphosphoric acid. The products are then converted to pigment form by heating the moist press cake in water under pressure at 100‹ to 200‹ C., optionally in presence of a solvent, or by distilling off the water after the addition of solvent and then heating at normal pressure. The solvents used include hydrocarbons optionally substituted by halogen or nitro groups, dimethyl formamide, alcohols and glycols and other solvents are also mentioned. The pigments give red and violet shades in printing inks, lacquers and p.v.c.

Abstract: 1396720 Electro-chemical decomposition of hydrogen peroxide FRANCE ARMED FORCES MINISTER OF 21 Dec 1972 [23 Dec 1971] 59266/72 Heading C7B A process for heterogeneous catalysis of the decomposition of hydrogen peroxide in solution, uses as catalyst a transition metal of one of Groups I, VI, VII and VIII of the Periodic Table (e.g. Ag or Pt) or a compound thereof, which during the decomposition is subjected to a cathodic or an alternating voltage to polarize it electro-chemically. The hydrogen peroxide solution may contain a salt or compound for en-  hancing electrical conductivity, stabilizing pH  (as buffer) and inhibiting catalytic decomposition, e.g. a phosphate. The catalyst may be subjected to cathodic polarization prior to catalytic decomposition. As shown, Fig.3, variable flow oxygen generator comprises a catalysis chamber 19 containing a hydrogen peroxide solution with phosphate buffer, and at least two electrodes brought under voltage by a current generator 23, at least one of the electrodes being formed by the catalyst and, being cathodic, a buffering chamber 20 for collecting gas released in the reaction and in which the gas pressure is determined e.g. by a pressure gauge 21 or a pick-up device (24), Fig.4 (not shown), and a device 22 (25) for controlling the voltage in dependence upon the gas pressure. The catalysis chamber 12, Fig.2, may contain a reference electrode 13, a working (catalyst) electrode 14 e.g. connected by Cu wire 18, and a counter-electrode 15, thermal balance being ensured by circulating a thermostatic liquid in jacket 11; gases liberated may be discharged through tube 16.

Abstract: 1,219,990. Electrodes for piezoelectric elements; cavity resonators; magnetrons. LITTON INDUSTRIES Inc. 13 Dec., 1968 [4 Jan., 1968], No. 59385/68. Headings H1D, H1E and H1W. The electrodes of a piezoelectric device consist of several layers of metal including an embossed layer. As shown, the invention is applied to a bimorph having two elements 1, 2 made, e.g. of BaTiO 3 , PZT or LZT or of mixtures of these. The electrodes consist of layers 3, 4, 5 respectively of chromium, copper and gold, these layers being deposited, e.g. by vapour deposition. The central electrode of the bimorph includes a plate 6 of molybdenum provided with deposited layers 7 of gold. The elements 1, 2 are attached to the central plate 6 by means of a bond formed by diffusion of embossed gold sheets 8, 9 into gold layers 5, 7 under heat and pressure (e.g. 40 lb./sq. inch at 600 C.). During this process, the gold sheets 8, 9 are flattened, but retain a certain amount of resilience essential to the operation of the bimorph. The plates (not shown to scale) may be of rectangular or annular form. It is stated that they may form part of the walls of a cavity resonator, e.g. of a coaxial magnetron, or can be used for moving tuning means in such cavities.

The blade 39 lies within a slot 35 of one of a pair of crimping jaws 28, 30 for enclosing articles (A), Fig. 2 (not shown), in portions of a continuous tubular web (18), pivotable links 48, 50 and knife holder arms 40 forming a parellogram linkage for advancing the blade 39 from the slot 35 so that teeth formed on its cutting edge co-operate with a clearance slot of the lower jaw 30. As the shaft 24 and a corresponding shaft 26 of the lower jaw 30 rotate, a cam follower arm 72 having a guide shaft 74 connected by links 86 to the holder arms 40 follows a face cam 62 adjustably bolted to a frame block 40. In the upper part of its rotational cycle, the arm 72 is moved outwardly of the block 40, compressing the energy-storing springs 64 and acting on the parallelogram linkage to withdraw the blade 39 into its slot 35. As it approaches the lowest point in the cycle, the arm 72 passes over a step (70), Fig. 7 (not shown), in the cam track 62, the springs 64 acting to trigger the knife blade 39 by outward movement of the shaft 74, which acts through the linkage to urge the blade 39 into the slot 35, effecting a sawing action on the web (18).

A combined gyroscope and accelerometer comprises a housing 11, a pair of synchronous electric motors 17 disposed vertically one above the other in the housing, a flexible wire 14 extending between and secured by collets 15 to the motors for rotation therewith, a gyroscopic rotor 12 secured to the middle of the wire 14 by a collet 20, so that the rotor rotates in a plane normal to the wire, four pairs of permanent or electromagnets 30 symmetrically disposed round the rotor on opposite sides thereof to compensate for the torques produced as the wire 14 flexes on precession of the rotor, four pick-offs 29 symmetrically disposed round the rotor 12 to sense precession of the rotor about axes normal to the wire 14, and producing output signals which are also fed to torques 27 maintaining the rotor in the plane normal to the wire and two pairs of diametrically opposed capacitive pick-up plates 31 symmetrically disposed in the housing 11 (only one plate 31 shown) sensing horizontal displacement of the rotor 12 due to acceleration and producing signals proportional thereto, these latter signals also being fed to force balance coils 32 to restore the rotor 12 to a central position in the housing 11. The device may thus be used as a gyroscope, turning of the vehicle on which it is mounted causing precession of the rotor 12 sensed by pick-offs 29, or as an accelerometer by displacement of the rotor 12 sensed by the capacitive plates 31. The collet 20 may be a three jaw or a ball collet and to prevent windage effects on the rotor the housing 11 is preferably evacuated. The rotor is normally driven by the motors 17 through the wire 14, but to bring the rotor to speed auxiliary motors 34 acting directly on the rotor are used to prevent undue torque on the wire 14. The rotor is preferably made with a central layer 24 of insulation to reduce eddy currents therein, though laminations or sintered materials maybe used instead.
