Abstract: 1,093,749. Circuits employing bistable magnetic elements. MINSKY ZAVOD SCHETNYKH MASHIN IMENI G.K. ORDZHONIKIDZE. May 13, 1966, No. 21285/66. Heading H3B. A ferrite core memory matrix is threaded using a plurality of slidable racks. Each rack, Fig. 2 (not shown), comprises an elongated base member provided with a plurality of sockets which contain one or more cores positioned on edge, the cores in each socket being arranged one above the other. Initially, the racks are arranged so that all of one of the ends of the base members are positioned against a stop 15, Fig. 1a. The base members are of different lengths and hence in the position of Fig. 1a are arranged in echelon formation with the cores arranged coaxially in columns, the columns being staggered by the distance between cores in the columns. The X coordinate wires 17 are then passed through the columns. A bar 14 positioned adjacent the end of the longest rack and perpendicular thereto is then moved towards the stop 15 and displaces the first rack, all others being locked by the stop 15. On the arrival of bar 14 at the end of rack 2 stop 15 shifts downwards and releases rack 2 which moves with rack 1. As soon as rack 2 is shifted relative to rack 3 by a distance equal to one column pitch rack 3 begins to move and so on until the racks are in the position shown in Fig. 16. In this position the cores are wired with the 7-coordinate wires 20. The inhibiting wire is threaded at this time and if the sockets contain two cores the first column of the lowest layer is wired and then the wire is passed back via the first column of the uppermost layer and then back through the lowest layer of the second column. After this step the bar 16 is moved in the direction 22 until it abuts pins 21 when bar 14 moves in the direction 23 and the racks move successively to the left by a half pitch relative to each other, Fig. 1c. After this, the cores are wired with the read-out wire 24 which threads all the cores.

Title: Improvements in or relating to automatic gain control devices for electric signalling systems
IPC: H04B3/06
Filed: 1932-08-02
Abstract: 405,295. Transmission systems. ELECTRICAL RESEARCH PRODUCTS, Inc., 195, Broadway, New York, U.S.A.-(Assignees of Horton, A. W.; 160, Prospect Street, East Orange, New Jersey, U.S.A.) Aug. 2, 1932, No. 21684. Convention date, Aug. 29, 1931. [Class 40 (iv).] In a system in which an automatic gain control device responds to signals of above a given volume level, the sensitivity of the device is reduced when the noise reaches a given level. The change in sensitiveness may be made in one or more steps. As shown, peaks of speech from circuit 2 operate a gas-filled trigger tube 33 to energize M which, by discharging condenser 17 increases the gain of the amplifier 4, 5. Outgoing speech of sufficient volume operates the trigger tube 24 to energize 25 and so open the discharge circuit and through the medium of the rectifier 20 charges condenser 17 to reduce the gain of the amplifier. The sensitivity of relay M is determined by the effect of its winding 39 the sensitivity being reduced in steps as resistances 70, 701 are cut into its circuit under conditions of continuous abnormal noise, the control being effected as follows. Relays A1, A<1>1 are in series with and are more sensitive than M, A1 being operated by a moderate noise level and both relays by an excessive level slightly before M. A1, A<1>1 energize respectively. A3, A<1>3 which respectively release A2, A<1>2 to cut resistance into the circuit of winding 39. A1, All and A3, A<1>3 follow the syllables of speech but A2, A<1>2 have hold-over times such that they are held energized during speech. A3, A<1>3 which may be omitted have hold-overtimes such that they are held energized continuously when A1, A<1>1 are vibrating comparatively rapidly as with certain types of noise. Specification 367,616 is referred to.

Abstract: 982,223. Machine tool details. CINCINNATI MILLING MACHINE CO. May 31, 1963 [Aug. 8, 1962], No. 21865/63. Heading B3B. [Also in Division H2] In a switch for controlling the movement of a machine tool member, an operating lever 10 is movable into six actuating positions, being latchable in two of these positions and spring biased into a central neutral position. The lever 10 is mounted in a housing 19 by a ball 12 for pivotal movement, the ball 12 providing mounting means for four actuating elements 33 which operate switches through spring-loaded plungers 36, one switch being a latch switch, and the others closing circuits for feeding the tool member to the right, left, or at a rapid rate respectively. Extending from the lever 10, a spring-loaded plunger 14 locates the lever by the end 49 engaging niches 50-55 in a cutout 48 in a plate 45. The niches indicate the six positions of the lever and two extensions 57 prevent the lever from being moved from a feed position to a rapid feed position without passing through the neutral position. The lever 10 is held in its feed positions, i.e. niches 50, 51 by a detent plate 67, attached to the enlarged end of a stem 70 made of non-magnetic material, which together with a winding 76 forms a solenoid. The upper surface of plate 67 has a pair of depressions which engage the end 49 of the plunger 14 when the solenoid is energized and hold the lever in either of its feed positions, i.e. one of the elements 33 depresses one plunger to operate the latch switch at the same time as another operates one of the other switches. When the end 49 of the lever is in one of niches 52, 53 only one of the other switches is actuated, i.e. the tool member is moved to the right or left at a feed speed and the lever is not latched, but when the end 49 is in one of niches 54, 55, the switch for rapid speed is actuated as well as the normal right or left speed, but the lever is not latched in these positions. The lever is released from one of its latched positions by a trip dog actuated by the tool member when it reaches a predetermined position, and opening a limit switch to deenergize the solenoid winding 76; the lever may also be released by manually returning it to its neutral position.

Title: Pitch control for aircraft sustaining rotors
IPC: B64C27/54
Filed: 1947-08-08
Abstract: 634,529. Helicopters. AUTOGIRO CO. OF AMERICA. Aug. 8, 1947, No. 21893. Convention date, Aug. 7, 1942. [Class 4] In a rotative winged aircraft controlled by cyclical and collective variation of the blade pitch, the pitch control mechanism includes a substantially irreversible mechanism to prevent aerodynamic loads developed in the blades being transmitted to the control system and the arrangement is such that the blade pitch angle is substantially unaffected by blade flapping. The rotor hub assembly comprises a hub 10 extended into a hub spindle 11 mounted in bearings 12 in a fixed sleeve 13. A gear ring 15 is secured to the lower end of the spindle 11 and meshes with a pinion 16 mounted on a drive shaft 17. Each blade 18 is connected by a root fitting 19 and bearings 21 to a spindle 20 formed with an apertured eye 22 and mounted on a flapping pivot 23 supported by the rotor head 10. The inner end of each root fitting 19 is formed with a worm-wheel segment 25 with which meshes a worm 26 mounted on brackets 27 extended from the apertured eye 22. The end of the worm spindle is provided with a lever 28 connected by a link rod 29 to a rotative swash ring 30 mounted on a bearing 31 on a non-rotative swash member 32 provided with a depending skirt 36. The swash member 32 is spherically seated on a member 33 capable of sliding movement on the sleeve 13 for effecting collective pitch control under the action of a lever 52 and a control rod 51. Cyclical pitch control is effected by rocking the swash member 32, 36 about the member 33 by two controls such as that shown at 37, 40, 43, 44 disposed at right angles to each other. The swash ring 30 is driven from the rotor hub 10 by a scissors linkage 34, 35. The above arrangement produces small variations in blade pitch as a result of blade movements about the flapping axis and in another arrangement (Figs. 4-7, not shown) the axis of the worm is parallel to the axis of the rotor hub so that the control rod 29 (Fig. 1) is positioned coaxially within the hollow pivot pin 23. In a further arrangement (Figs. 8 and 9, not shown), the pitch control mechanism is rendered independent of the blade flapping movements by placing the flapping pivot outboard of the root fitting 19 (Fig. 1). A drag pivot inclined to the axis of the flapping pivot is also included. Specifications 159,224, [Class 114], and 477,349 are referred to.
