Abstract: 445,298. Dropping bombs and like missiles from aircraft. AKT.-GES. C. P. GOERZ OPTISCHE ANSTALT, Pressburg, Bratislava, Czecho Slovakia. Oct. 5, 1934, No. 28601. Convention date, Oct. 6, 1933. [Class 92 (ii)] Apparatus for automatically determining the release angle OB<2> when open sights are used has the backsight O first adjusted above a horizontal line O<1>A<2>A<1> by an amount 001 proportional to the time of fall T, the " release " foresight B<2> being then adjusted horizontally by an amount OB<1> proportional to the distance between two target-timing foresights A<1>, A<2> and being moved downwardly by a clock-driven screw 12 at a constant speed represented by OO<1>/T during the time the target is followed. Further, to correct for the trail angle, the frame carrying the screw 12 is adjusted about a shaft 10 driven by the clock 9 in accordance with a pointer 11e, and scale 8c. The apparatus shown is mounted on an L-shaped member 1v, 1h, which can be swung in azimuth about an axis pin 2. The backsight O is adjusted vertically by turning a screw 4. The frame 8 carrying the foresight B<2> is mounted for adjustment along the bar 1h by a left-handed screw 6l connected by a clutch 6 to a right-handed screw 6r carrying the foresights A<1>, A<2>. By turning the knob 6a so that A<1> is brought into line with A<2>, the distance OB<1> is made equal to the distance A<1>, A<2>. The clock is started when the target is observed in the line OA<1> and stopped when the line OA<2> is reached. The line OB<2> then gives the release angle. In a modification, the screw 12 is arranged horizontally and the nut 15 thereon is connected to the foresight B<2> by a right-angled bell-crank lever. The apparatus is further simplified by dispensing with the screws 6l, 6r and mounting the foresights A<1>, A<2> on a member slidable on the bar 1h.

Title: Magnetic compasses
IPC: G01R33/025
Filed: 1971-12-21
Abstract: 1368238 Electric indicating systems DEFENCE SECRETARY OF STATE FOR 21 Dec 1971 [24 Sept 1970] 45515/70 Heading G1N The invention is an improvement on that of Specification 853942 wherein the direction of the earth's magnetic field is determined on a vehicle by two magnetic field detectors mounted at spaced points on the vehicle where deviating fields due to the vehicle itself are parallel to each other and bear a substantially constant ratio, the output signals from the detectors being combined in the appropriate ratio and used to operate a compass pointer indicating the true direction of the earth's field independently of the deviating fields. The improvement relates to means for modifying the above ratio in accordance with the actual heading of the vehicle. As described in Specification 853942, the three-phase windings of two flux-gate compasses 24, 26 (Fig. 2) mounted on the vehicle as described above are connected to the stator windings of synchros 28, 30, whose rotors are both mounted on a shaft 32. The signal from the rotor winding of synchro 30 is connected in series opposition with a proportion of the signal from the rotor winding of synchro 28, the difference being amplified at 44 to energize motor 38 driving the shaft 32 until the input to amplifier 44 is zero. It is shown that the angular rotation of the shaft, indicated by a pointer 40, is the heading of the vehicle relative to the true magnetic North. In the present invention the potentiometer determining the proportion of the signals consists of a pre-set variable resistor 18 and a heading- variable resistor 2 comprising an eight-section outer ring 4a-4h (Fig. 1), each section being connected to an inner ring 8 by an adjustable resistor 6a-6h. A wiper arm 10 pivoted at the centre 11 is driven by the motor 38 to select the appropriate resistor 6 consistent with the heading of the vehicle. The adjustments to resistor 2 are initially made by turning the vehicle to different known headings and making the compass readings agree by varying the appropriate resistor 6a-6h.

Abstract: 1,002,527. Semi-conductor devices. STANDARD TELEPHONES & CABLES Ltd. Nov. 19, 1963, No. 45601/63. Heading H1K. [Also in Division B3] Portions of a layer 5, Fig. 2, of conducting material are removed from a surface of varying height by a spark erosion process. In the manufacture of a solid state electrical triode device, a body 1 of dielectric material such as gallium arsenide has its upper surface shaped by abrasion or photo-etching to produce grooves 4 and a step 3, Fig. ld. This surface is coated by vacuum evaporation with a layer 5 of high work function metal such as gold. A conductor wire 6 is secured to the layer 5 by compression bonding and upper portions of the layer are then removed by a spark erosion electrode 8, Fig. 2, which is scanned over the surface; either the electrode or the workpiece may be moved during the scanning. Alternatively an electrode of the same working area as the surface may be used, Fig. 3 (not shown). The metal portions 5 remaining in the grooves are then coated by vacuum evaporation with a layer 10, Fig. 1j, of insulating material such as magnesium fluoride on the top of which a layer 11 of cathode metal such as tin is applied by evaporation. A dimple 12 is formed in the base of body 1 by abrasion or electrolytic jet etching in a solution of indium, and a layer 13 of high work function metal is applied by evaporation. Anode and cathode connections 14, 15 are attached to the layers 13, 11 and the wire 6 is used as the grid connection for the triode.

Title: Liquid ring pumps
IPC: F04C19/00
Filed: 1963-11-20
Abstract: 1,011,451. Liquid-ring pumps. I. C. JENNINGS. Nov. 20, 1963 [Nov. 27, 1962], No. 45858/63. Heading F1C. A liquid-ring pump has means for bleeding off some of the sealing liquid when operating below its designed vacuum capability, such as during starting. This reduces surging and horsepower requirements of the pump when operating under such conditions. In a pump for moderate to high vacuums, for example corresponding to more than twenty inches of mercury, gas enters through inlets 36 and ports 40 in stationary members 38, and leaves through ports 42 and chambers 44 each having three outlets 52, one of which (not shown) extends vertically downwardly. Make-up sealing liquid supplied through a conduit (not shown) keeps the pump cool. When the pump is operated at relatively low vacuum conditions or during starting, the higher pressure of the sealing liquid therein causes valves 58 in conduits 56 to open to release sealing liquid from annular chambers 54 through conduits 60 each communicating with one of the outlets 52. Alternatively, the valves 58 may be omitted and each conduit may extend directly to the bottom of a gas-liquid separating tank connected at the top to the pump outlet, the flow of sealing liquid to and from the pump through the conduit being controlled by the pressure of the sealing liquid in the pump and the liquid head in the separating tank. In both embodiments the unused outlets 52 are closed by baffle plates (not shown). A chamber 46, communicating with the interior of the pump through an aperture 50, is capped by cover plates 48 and is vented through conduits or valves (not shown) when unloading or drainage of the pump is desired. Specifications 324,249; 324,286 and 995,415 are referred to.

Abstract: 1506609 Disc brake assemblies O & K ORENSTEIN & KOPPEL AG 13 Nov 1975 [14 Nov 1974 14 Dec 1974] 46885/75 Heading F2E A disc brake assembly for an escalator comprises a brake disc 2 keyed to a driving shaft 1 of the escalator, and a pair of brake pads 7 disposed on opposite sides of the disc 1, each pad 7 being movable during brake actuation and by their braking effort on the disc from a "starting" position close to the axis of rotation of the disc 2 along a predetermined arcuate path disposed non-radially relative to the axis towards a "finishing" position disposed adjacent the outer periphery of the disc 2, to thereby vary the effective radius at which the pads act on the disc 2 and hence increase the braking torque during braking. As shown, each pad 7 has a pair of carrier plates 7a pivotally carried on actuating links 6, each link 6 being pivotally carried at its middle part between support plates 5a, and the links 6 being respectively pivotally connected to output members 11a, 11b of an actuator 11. The actuator 11 is energizable (e.g. by an electric current, or air under pressure) to release the pads 7 against the action of a spring 11c. The plates 5a are supported on an arm 5 which is keyed to a shaft 4 disposed parallel to shaft 1, and a second arm 8 keyed to shaft 4 is connected to an hydraulic damping device 9. A spring 4a coiled round shaft 4 biases the shaft 4 in a clockwise direction. De-energization of actuaIor 11 when the disc 2 is rotating causes application of pads 7 to disc 2, thus subjecting the disc 2 to braking torque and the pads 7 to disturbing forces tending to drag them along the disc surfaces-when the torque on the disc 2 reaches a sufficiently high value the torque exerted by spring 4a on shaft 4 is overcome, the arms 5, 8 rotate and the pads 7 move in the predetermined path. The arrangement ensures progressively increasing deceleration of the escalator. Figs. 4, 5 (not shown) illustrate a preferred form of damping device 9 to ensure a progressively decreasing damping effect.
