Title: Automatic gun
Inventor: POST LOTHAR
IPC: F41A9/37
Filed: 1983-03-28
Abstract: In the case of the automatic firearm, the external drive encloses two control rollers 20 l, r which can rotate in opposite directions and each have a control groove on the circumferential side in order to move the breech body 18 axially backwards and forwards. A drive 38 having gearwheels for the control rollers 20 l, r has allocated to it a drive 52 for converting a continuous rotary movement into a step by step rotary movement of a left or right transportation shaft 66 l, r, which can be selected by means of a transportation coupling 54, of an ammunition feed 50 (for bolted cartridges) having a feed unit 64 integrated with it. When the breech body 18 moves forwards in the direction of an arrow 40, a cartridge is moved by the ammunition feed 50 into the insertion position. In order to interrupt firing, the ammunition feed 50 is decoupled from the external drive, and a sear 26 brings the control rollers 20 l, r to rest when the breech body 18 is located in its original position to start firing again. <IMAGE>

Title: Temperature sensors
Inventor: MCKEMMIE ROSS CHRISTISON
IPC: G05D23/24
Filed: 1983-10-25
Abstract: A temperature sensor for a system for controlling the temperature of e.g. a building or refrigerator comprises two or more thermistor sensing elements 11A, 11B etc respectively connected in series with first reference resistors 12A, 12B, etc. Each series circuit is connected in parallel and the parallel network is connected in series with a second reference resistor 13. A comparator device 16 is coupled to compare the output of each respective series circuits 11A, 12A; 11B, 12B, etc with a reference input 15 and an output device (OR-gate 18) delivers a control signal. The arrangement is such that the output is related to a weighted average of the temperatures of the various thermistors 11, the weighting being in favour of the warmest thermistor and being dependant upon the values of resistors 12, 13 and upon the temperature difference between the thermistors. So that any failed thermistor is effectively ignored. <IMAGE>

IPC: B63B35/04
Abstract: 839,546. Cable reels and guiding means. POSTMASTER GENERAL, ASHBY, R. J., and JOHNSON & PHILLIPS Ltd. Sept. 3, 1956 [Sept. 2,1955], No. 25272/55. Class 99(2). [Also in Group XXXIII] Apparatus on a cable laying ship or elsewhere for storing cable having bodies such as repeaters 16 connected at intervals therein comprises a hollow cone 12 with a slot 14 in its wall extending to the top.. The repeaters 16 are located within the core 12 on a platform 22 and the cable passes through the slot 14 and is coiled around the exterior of the cone. As shown, the upper part 12b of the cone has a slotted guide tube 15 with a spring loaded non- return latch 17. During laying of the cable the latch 17 prevents a repeater 16 which has been raised above the latch 17 from moving downwards. To avoid too great an angle when withdrawing a repeater 16 an arm 26 is lowered and the repeater is drawn thereon from the guide tube 15, the arm 26 then being raised to deck position and the repeater drawn off. In a modification, Fig. 3 (not shown), a guide trough comprising a curved arm and adapted to swivel about a vertical axis replaces the arm 26. In another modification the cone 12 and tube 15 have each two slots the repeater 16 being tilted upwards and spaced apart. In a further modification, the repeaters are arranged in an upright position and in arcuate rows.

Patent GB-2138099-A (GB)
Title: Toothed coupling
Inventor: TACKE FRANZ
IPC: F16D11/00
Filed: 1984-04-06
Abstract: In toothed couplings with a compensation capability, the relative movement of those parts of the coupling which are in mutual toothed engagement does not allow the transmitted power to be increased, as would be desirable. The invention provides a toothed coupling for the transmission of high torques at high rotational speeds, in which a considerable increase in the transmitted power is made possible by the grinding of flanks of the external and internal crowned teeth of the parts during manufacture.
Patent GB-2158579-A (GB)
Title: Angular rate sensor system
Inventor: ALSENZ EVERT C
IPC: G01C19/56
Filed: 1984-05-10
Abstract: An angular rate sensor system is disclosed, consisting of a balanced resonant sensor. The sensor consists of a tuning fork or a piezoelectric material, preferably of quartz. The tines of the tuning fork are caused to vibrate electromechanically, for example, by impressing an alternating voltage on a pair of electrodes on each tine. This will cause the tines to vibrate. Any component of angular motion around the axis of the sensor causes a cyclic deflection of the tines at right angles to the normal driven vibration of the tines. If the rotational input to the handle of the sensor is applied through a torsion element, the resulting tine deflection is directed to cyclically rotate the entire sensor along the input/output axis. This deflection can be used for changing the capacitance of a capacitance bridge, or for generating an electric signal, due to the piezoelectric effect resulting from the deflection. Finally, the output signal may consist of a frequency-modulated signal or an optical pick-up may be used. The system may take various forms, including one, two, four, or eight tuning forks forming a unitary system. <IMAGE>

Title: Handle for drilling machines and/or hammer drills
Inventor: WANNER KARL
IPC: B25D17/04
Filed: 1985-01-11
Abstract: A handle for drilling machines and/or hammer drills is proposed, wherein a grip piece (7) oriented at an angle to the axis of the toolholder (3) is constructed so that it is at least as long as two hand widths and can be grasped with both hands by the user of the machine. The grip piece (7) is connected to the machine housing (2) via a bar (8) at such a point that one of the holding hands can grasp the grip piece (7) approximately in the prolongation or the axis (6) of the toolholder (3). Therefore one hand is located at the ideal point for the transmission of the feed forces to the machine, and hence to the drill, whereas the effect of torques which occur can be intercepted with the other hand without any auxiliary grip being required for this purpose. By the arrangement of at least one further bar (9 and/or 10) between grip piece (7) and housing (2), a particularly secure gripping construction of the handle (4) is obtained. <IMAGE>
