Title: Improvements in or relating to automatic piloting devices
IPC: G05D1/02
Filed: 1934-09-18
Abstract: 433,404. Automatic steering-gear for ships and aircraft. CONSTANTIN, L., 26, Rue EugÞne Flachat, Paris. Sept. 18, 1934, No. 26788. Convention date, Sept. 19, 1933. [Classes 4 and 114] [See also Group XXI] In an automatic steering system for aircraft, submarines, torpedoes, and other vehicles, an absolute direction indicator, such as a compass, is associated, by electrical relay mechanism, with a wind vane by which the rudder is adjusted to correct lateral movement of, for example, an aeroplane relatively to the air or other medium. The Constantin wind vane shown applied to an aeroplane, includes vanes mounted on the forward angles of a trapezium having one pivot 7 fixed and the long parallel side 6 extended so that the direction in which the apparatus faces relatively to the centre line of the aeroplane may be adjusted by a gyroscopic compass 8 through an electric relay. One of the sides of the trapezium forms a lever 2 connected by a link 4 to the rudder 5. The lever 6 is adjusted by screw-and-nut mechanism actuated by a motor 14 which is supplied with current from the batteries 21, 22 so as to drive it in either direction according to whether the arm 10 on the ring 8<a> of the gyroscopic compass is engaging contact 12 or 13. The movement of the arm is limited by brush 17 sliding clear of either of the contacts 19, 20 as the arm 6 is operated. The electric relay may be controlled by any one of a number of absolute direction indicators by the switch shown in Fig. 2. The three leads from the relay are connected directly to rings 23, 24, 25 and the rings 24, 25 are always connected to contacts 30, 28 on the arm 26 which may be rotated until the contacts 30, 28 engage corresponding contacts 13a, 12<a> on any one of a number of compasses or other direction indicators.

Title: Binary half adder
IPC: G06F7/50
Filed: 1961-07-24
Abstract: 957,101. Tunnel diode logic circuits. RADIO CORPORATION OF AMERICA. July 24, 1961 [Aug. 22, 1960], No. 26794/61. Heading H3T. [Also in Division G4] A binary half adder circuit comprises two parallel branch circuits, each including a transistor, negative resistance means being included in at least one of said branch circuits for steering operating current into one or the other of said branch circuits in accordance with the number of pulses received concurrently. As described, a half adder comprises two parallel branch circuits, a first branch including a transistor 24 and a second branch including a transistor 16 and tunnel diodes 14, 18. The characteristic for the second branch is shown at 57, 58, 59, 60, 61, 62, Fig. 4, and is correct for no input pulses or just one input pulse applied to the input terminals 30, 32. If two input pulses are applied simultaneously, the transistor 24 conducts and the characteristic 57-62 of Fig. 4 is changed. Current is supplied from a constant current source 10 which current may be a steady D.C. or in the form of pulses coincident with the -information pulses. With no input pulses applied, the circuit operates at point 72, the tunnel diode 18 being in a low voltage state and steering the current into the tunnel diode 18 so that none flows into the transistor 16. When one input pulse is applied to terminals 30 or 32, the load line for resistors 34, 36 shifts to the dotted position 74 and there is no stable intersection corresponding to point 72 so that the operating point shifts to 76 where the tunnel diode 18 is in its high voltage state thereby causing the transistor 16 to conduct and an output representing " 1 " to appear at the sum terminal 42. When input pulses are applied to terminals 30, 32 simultaneously, the tunnel diode 14 switches to the low current region of its high voltage state and the tunnel diode 18 therefore switches back to its low voltage state to cut off the transistor 16. The tunnel diode 14, however, in its high voltage state, turns the transistor 24 on to cause an output representing " 1 " to appear at the carry terminal 46. The circuit may be reset by a negative pulse from a source 38. In a slightly modified circuit (Fig. 2, not shown) the tunnel diode 18 is connected between the anode of the tunnel diode 14 and earth.

[Also in Group XXXV] A method of moulding a resin mixture in which an exothermic reaction takes place, e.g., polyester or ethoxyline resin, comprises filling a mould with the mixture, heating the mould to expedite the start of the exothermic reaction, measuring the temperature of the casting and switching off the heat when the temperature of the mould is such that the final subsequent temperature reached by the resin, as a result of the exothermic reaction, would be sufficient to cause damage to the resin or to any embedded electrical component. The mould may then be cooled to keep the temperature to a minimum during the subsequent stages of the exothermic reaction and after the reaction has taken place again be heated to complete the curing of the resin. In the form shown the mould 20 is heated in an oven by an electric resistance 22. A temperature-sensitive resistance 24 embedded in the mould causes a relay 26 to open the heating circuit and at the same time energize a second relay which closes a self-holding contact in a circuit through a time switch 35. This maintains the post-curing heating when the mould temperature falls enough for the heating circuit to be closed again. In another form heating is effected by infra red lamps. In either case cooling may be effected by a fan diverting air over the mould.
