Abstract: 898,181. Transistor bi-stable circuits. ERICSSON TELEPHONES Ltd. March 29, 1961 [May 5, 1960], No. 15857/60. Class 40(6). A bistable control circuit for an electromagnetic relay having a coil of the relay connected into the load circuit of one or both of two switching elements includes a core of "square loop" material having two output windings, one end of each being connected to the control electrode of a separate switching element. The two windings 1, 11 of a polarised relay are connected into the collector circuits of transistors T1, T2 which forms a bi-stable trigger circuit to switch the current through either one or other of the windings. Triggering pulses are applied via diodes D1, D2 to the bases of the transistors from output windings on a square loop core when the state of the core is switched by any suitable means. The relay may be polarised as shown by a third winding or by a permanent magnet. A single winding relay, Fig. 2 (not shown), may be used, connected into the collector circuit of only one transistor. Valves may be used in place of transistors.

Title: Apparatus for trimming large bodies of resinous cellular materials
IPC: B29C37/02
Filed: 1964-04-17
Abstract: 1,027,875. Trimming cellular bodies. ALLIED CHEMICAL CORPORATION. April 17, 1964 [April 30, 1963], No. 16092/64. Heading B5A. Apparatus for trimming large elongated bodies of cellular resinous material, e.g. polyurethane foam, comprises a conveyer 20 along which the cellular body 21 is moved, a pair of centring guide members 52, 53 on opposite sides of the conveyer, each including a series of spaced vertically disposed rollers 57 supported between a pair of angle members 54, the guide members being mounted on lateral members 58 (Fig. 4, not shown), which are slidably mounted on cross-rods 61 and to which connecting bars 78 ... 81 are pivotally secured, the other ends of the bars being secured to push-pull rods 82, 83 moved by means of an air piston 102. High pressure air supplied to the piston 102 moves the guide members 52, 53 transversely to position the cellular body in a longitudinal divertion essentially parallel to the planes defined by the rollers 57. The apparatus also includes side trimming means 74 downstream of the centring guide means, and bottom trimming means 136 downstream of the side trimming means. Once the cellular body has been initially centred, an air operated clamp 114 closes on a brake drum 116 mounted on the push-pull rod 82, thus fixing the guide member 52. Low pressure air is then admitted to piston 102 so as to permit the cylinder arm 101 and cross-arm 96 to be moved downstream by forces acting outwardly on the guide member 53 due to irregularities in the width of the cellular body. The side trimming means comprises two drums 73, 74 having surfaces covered with e.g. silicon carbide, and are individually driven in the opposite direction to the movement of the cellular body. The drums 73, 74 are adjustable by assemblies 128, 129 on rails 126, 127 so that the lateral distance between them is slightly less than the width of the mould. The bottom trimming means comprises a horizontally disposed trimming drum 136 having its upper surface disposed above the level of conveyer belt 20 by a predetermined distance, set according to the amount of material to be removed by raising or lowering a conveyer frame 139 (to which the drum is attached), by a jack assembly 142. Immediately downstream of the drum 136 is a second conveyer 141 having its surface on the same horizontal level as the top of drum 136. The drum 136 rotates against the direction of movement of the advancing cellular body and has its surface coated with hard particulate material. The top of the cellular body may be trimmed by an upper horizontal trimming drum 150 whose vertical position may be adjusted by a wheel assembly 151. Overhead rollers 37, 143 pivotally mounted above the conveyers 20, 141 respectively, exert a moderate pressure on the cellular body and ensure movement of the body along a steadily advancing path during trimming. In alternative constructions the centring guide means may be operated by springs or pneumatic pressure.

Title: Improvements in means for operating aircraft controls
IPC: B64C13/00
Filed: 1921-06-14
Abstract: 185,849. Salmon, P. June 14, 1921. Hydraulic transmission of power; machines and apparatus.-A servo-motor for assisting an aircraft pilot to operate the control surfaces, comprises a hydraulic pump of the cog-wheel type and a hydraulic motor of the oscillating vane type, the ports leading to the motor being controlled through a shaft about which the vane oscillates. The pump has three pump wheels 6, 7, 8 driven by a windmill 4. The wheels are mounted in a barrel 10, which can be rotated in its casing 11 to connect the port 17 to one or other of the ports 18 through one or other of the passages 15, and so to cause fluid to be pumped from the passage 19 to the passage 20, or vice versa. The passages 19, 20 communicate respectively through ports 54, 55, Fig. 6, with the spaces between the fixed abutment 24 and the oscillating vane 25 of the motor. The cables 1, Fig. 1, leading to the control surfaces are connected to levers 2, the ends of which are connected to wires 5 and 28. The wires 5 pass around a drum 36, Fig. 3, and lead to the pilot's control wheel. The wires 28 pass around a drum 27, Fig. 3, fixed on a hollow shaft 26 that is secured to the oscillating vane 25 of the motor. When the pilot operates the wires 5, he turns the levers 2, and so takes part of the load. The pull on the wires 5 also turns the drum 36 and, through a sun-wheel 35 and planet wheels 33 on a spider 32, a shaft 31, whereby the pump barrel is rotated and liquid pumped to one side or other of the oscillating vane 25 to turn the drum 27 and exert a further pull on the levers 2 and the control surfaces through the wires 28. The movement of the drum acts through a crown wheel 34 and the planet wheels 33 to return the spider 32 and shaft 31 to the central position. In a modification, the pump barrel is fixed and its casing 11 rotatable. To put the hydraulic apparatus out of action and permit of the control surfaces being actuated entirely by hand-power applied through the wires 5, a cock 37 is turned to open communication between the passages 19, 20 and lock the shaft 31 carrying the spider 32. Spring-loaded relief valves between the passages 19, 20 limit the pressure in the motor. The angular movement of the motor abutment 25 is arrested when ports 44, 45 at its respective sides are connected together through a cavity 46 or 47 in the cylinder casing. Leakage is compensated for by liquid passing from a reservoir 49 through valves 50. The reservoir also supplies liquid to spaces 52, 53 at the end of the pump casing to prevent air from being sucked in.
