Patent GB-1137629-A (GB)
Title: Automatic control circuit for maintenance of a set condition such as the course of a ship
IPC: G05D1/02
Filed: 1966-08-24
Abstract: 1,137,629. Automatic control. W. FINK. March 8,1967 [Aug. 24,1966], No. 38082/66. Heading G3R. In an error-actuated automatic control system for a variable, inhibiting means prevent operation of correcting means until the error exceeds a threshold value, but do not become effective again until the error has been removed and the variable substantially stabilized near the desired value. As applied to the automatic steering of a ship, signals dependent on course deviation and rudder position, derived from variably obscured photocells associated with a compass and the rudder, are applied to transistor amplifiers the outputs of which are opposed to obtain an error signal which is effective through transistor relay circuits to operate a rudder servomotor in the appropriate direction to correct the course. An adjustably biased transistor switching circuit responsive to the course deviation signal maintains the relay circuits, and hence the rudder servomotor, inoperative until course deviation exceeds a predetermined value, but an adjustable resistancecondenser delay circuit maintains the relay circuits effective for a period after the course deviation has been restored within the predetermined value. Adjustable resistors are provided to permit decrease of the sensitivity of control in rough weather and the alteration of mean rudder position to counter wind or tide effects.

Title: Photosynthesis of iron enneacarbonyl
Inventor: BEUTNER HEINZ PAUL
IPC: C01G49/16
Filed: 1967-08-18
Abstract: 1,130,676. Iron enneacarbonyl. INTERNATIONAL NICKEL CO. OF CANADA Ltd. 18 Aug., 1967 [25 Aug., 1966], No. 38131/67. Heading C1A. Iron enneacarbonyl, Fe 2 (CO) 9 , is prepared in a continuous process by irradiation of pure Fe(CO) 5  at a temperature less than 20‹ C. with light of wavelength exceeding 400 mÁ and having its intensity predominantly in the wavelength range 400-700 mÁ. The Fe(CO) 5  is purified by distillation and preferably used immediately to minimize decomposition to Fe 3 (CO) 12 , whose presence causes reduced yields of product. The light used has a wavelength greater than 400 mÁ, to avoid rapid deposition of product on the walls of the reaction vessel halting the reaction, and less than 700 mÁ, to reduce the optical path length necessary for total absorption of light. The product Fe 2 (CO) 9  dissolves in Fe(CO) 5  to give a yellow solution which absorbs light in the wavelength region 400-600 mÁ, thus reducing the rate of reaction. This is avoided by keeping the temperature below 20‹ C., and also by making a 1-95% solution of the initial Fe(CO) 5  in a chemically and photo-chemically inert solvent, to minimize the solubility of the Fe 2 (CO) 9 , and thus to facilitate its removal by filtration.

Abstract: 327,126. White, A. E., (Delco-Remy Corporation). Sept. 22, 1928. Divided on 327,108. Spray carburettors.-An automatic passagerestricting valve, for maintaining the velocity of the charge at low engine suction, comprises two spring-loaded flaps 143 mounted on a shaft 144 which is carried by a short length of thin-walled tube 140 of slightly less diameter than the end of the manifold in which the tube is eccentrically mounted, the device being located between a throttle valve 125 and close to the intake port 16. Rich mixture is supplied to a Venturi 110 from a chamber 114 which is fed by a chargeforming device of the general type described in Specification 327,107, the main air being supplied by a manifold 10, the bottom inner surface of which is arranged to lie on approximately the same level as the throat 121 of the Venturi; the depression 122 may be fitted-in with metal or alternatively, the Venturi may be flush with the floor of the manifold. The points of anchorage of the valve openings 145 are disposed so that there is a greater restricting tendency for small incoming charges, the tension of the springs when the flaps are full open being only sufficient to initiate the closing movement. In the closed position the tension is sufficient to maintain the flaps closed when the throttle valve is nearly closed, thereby causing the whole of the charge to pass at high velocity through the crescent-shaped passage formed between the bottom of tube 140 and the manifold and thus to carry any unvaporized fuel particles to the engine to prevent the deposition of fuel on the walls of the intake passage 14. The manifold 10 may supply a plurality of branches, each provided with a charge delivering device and a passage-restricting valve, the throttles being coupled and the branches being interconnected by a pressure-equalizing passage 150.

Abstract: 972,522. Semi-conductor devices. ASSOCIATED ELECTRICAL INDUSTRIES Ltd. Sept. 14, 1962 [Nov. 6, 1961], No. 39649/61. Heading H1K. A semi-conductor device having a body of refractory semi-conductor material, e.g. silicon or germanium, with at least one junction between regions of different conductivity or conductivity type has the exposed surface of the junction hermetically sealed by a mass of insulating vitreous material fused to the surface of the body on each side of the junction and apart from terminals provided thereon. In one embodiment (Fig. 2) a silicon controlled rectifier formed of a wafer of N-type silicon 11 with a surface layer 12 of P-type material has part of layer 12 removed by etching to define an island 13 separated from the remainder of the surface layer by an annular portion of the N-type wafer, and the exposed edges of the P-N junction between the layer 12 and wafer 11 are hermetically sealed by glass 22. The island 13 of P-type material has a layer 14 of gold antimony alloyed thereto to form a low voltage P-N junction with a copper terminal member 15 soldered by a lead-tin solder to the goldantimony layer. An aluminium foil 16 is alloyed to the other face of the wafer and to a disc 17 of molybdenum previously coated on its opposite face with gold 19. The copper block 18 acts as a terminal and a heat sink and an aluminium control electrode 21 is secured to the layer 13 by ultrasonic bonding to complete the device. A further embodiment (Fig. 1, not shown) relates to a silicon rectifier in which an N-type silicon wafer with aluminium alloyed to a central region of one surface to form a P-N junction has alloyed to the opposite surface of the body a layer of gold-antimony to which is soldered by lead-tin solder a copper terminal. The aluminium layer is nickel plated (electroless) and then soldered to the copper terminal acting as a heat sink. As before the junction edge is sealed with glass. A final embodiment (Figs. 3 and 4) (Fig. 3, not shown) discloses an arrangement in which an aluminium foil is alloyed to and between faces of adjacent cylinders of N- and P-type material. The surface of the composite semiconductor body formed is oxidized before sealing of the junction edge by a glass annulus. A lower M.Pt. glass may be used in contact with the semi-conductor body, in each embodiment, with a further higher M.Pt. material subsequently applied. Several silicon wafers may be cut ultrasonically from a large silicon slice in which one or more junctions have been formed and sealing of the junction edges effected by a glass layer.
