Title: Electrified fence switching device
IPC: H05C1/04
Filed: 1979-10-19
Abstract: An electric fence generator (5) may be turned on or off at any point on the fence (3) by a pulse from a separate handpiece (17). D.C. isolator (6) connects the fence and the generator. The fence is also connected via pulse restriction and reduction means (11, 12) to a D.C. detector (14) feeding a bistable (15) which controls the main supply (8) to the generator via switches (9, 10). A storage capacitor (16) holds the state of the multivibrator (15) in the case of mains failure etc. Handpiece (17) comprises a battery with an earth probe (18) and a testing lamp (19). A D.C. pulse, applied to the fence by touching the positive terminal of handpiece (17) thereto, triggers the detector (14) to alter the state of multivibrator (15) and thus switch the generator (5) on or off as the case may be. <IMAGE>

Title: Finishing slide fasteners
IPC: A44B19/64
Filed: 1981-02-17
Abstract: A die holder 12 plvotably mounted at 13 on a frame 11 is angularly movable between a first (chain-dotted) position in which a slider 20 is supported on a slider rest 17 on one end of the die holder 12 and a slide fastener clain 23 is threaded through the slider 20 and a second (vertical) position angularly spaced from the first position and in which an end stop 22 is clinched about the chain 23 against a clinching die 14 adjacent to the slider rest 17. A clamp lever 27 pivotably mounted on the die holder 12 has at one end thereof a prong 29 which engages in an aperture 31 of a pull tab 21 to clamp the slider 20 in place on the slider rest 17 when the die holder 12 is in the first position, and which is automatically released of clamping engagement with the slider 20 by means of an abutment 32 while the die holder 12 is angularly moved from the first to the second position, whereby the slider 20 can freely be removed from the slider rest 17 when the die holder 12 is in the second position. When in the first position, depression of lever 36 unlatches shoulders 42 to permit spring 30 to pivot clamp lever 27 clockwise to engage the tab aperture 31. Movement from the first position is effected by pushing lever 52 to first unlock a projection 54 from a recess 55. A limit switch 59 serves to actuate a clinching punch 24 as the die holder reaches the second position. A pin 50 and slot 51 between the die holder and a pivotable support 46 limit the angular movement of the die holder. <IMAGE>

Title: Anvil plate for use with a surgical stapling instrument
IPC: A61B17/068
Filed: 1981-03-02
Abstract: The anvil plate is designed to narrow the opening through which the forwardmost staple in the instrument is formed. The anvil plate 22 (Figure 2) has a longitudinally extending raised central portion 23, with an extension 24 comprising an integral one-piece part of the raised portion 23 and lying at a slight angle thereto. The extension 24 constitutes an anvil and the upper surface 24a of extension 24 constitutes an anvil surface which is coextensive with but angled with respect to the upper surface of the raised central portion 23. The raised central portion 23 of anvil plate 22 has lateral edges which terminate in downwardly depending portions 25 and 26 (see also Figure 3). The downwardly depending portions 25 and 26, in turn, terminate in laterally extending flanges 27 and 28. Flange 27 is provided with a pair of extensions 29 and 30. Similarly, flange 28 is provided with a pair of extensions 31 and 32. Flanges 27 and 28 have forward extensions 27a and 28a which ensure that the legs of the row of staples straddling the raised portions 23 and extensions 24 are all supported at their outer ends except the forwardmost staple of the row. Thus the anvil plate fully supports the legs and crown portions of all but the forwardmost staple. <IMAGE>

Title: Switch for motor vehicle dashboards
IPC: H01H13/02
Filed: 1982-05-13
Abstract: A switch 10 for a motor vehicle comprises two push-buttons 11 and 12 or differently coloured transparent material partly covered by opaque sleeves 13 and 14. The push buttons are operationally connected together by a toggle rocker mechanism 24 which acts on switch contacts 30, 31. When a pushbutton 11, 12 is in a raised position, light is transmitted from a light source via a light transmitting member 34, 36 to the coloured pushbutton 11, 12 thereby indicating the switch position. When a pushbutton 11, 12 is in a depressed position, the sleeve 13, 14 thereon prevents the transmission of light thereto. <IMAGE>

Title: Re-enterable closure
Inventor: TIGHT TIM DEXTER
IPC: H02G15/18
Filed: 1982-06-15
Abstract: A recoverable wrap-around sleeve 4 secured by rails and channel 1,2 and which is used to seal a substrate can be re-entered and re-sealed in the following way. A central section of the sleeve is removed, after cutting away the rails and channel, leaving butts of the sleeve on the substrate. A new sleeve is then recovered across the butts of the old sleeve. If the new sleeve is to seal properly there should be no leak path between the old butts and the new sleeve. In order to avoid such a leak path, any gap between the remnants of the old rails must be filled with adhesive. This is achieved by providing means, such as deformations 7, at the base of one of the rails 1 or on a flap 3 adjacent one of the rails 1 which allows flow of adhesive 8 between the rails when the original sleeve 4 is installed.

Title: Automated machine safety
Inventor: MACMICHAEL DONALD BRUCE ATHERT
IPC: G07C3/00
Filed: 1982-09-20
Abstract: In order to detect an irregularity in the operation of a robot arm or machine tool programmed to perform a task repetitively, a machine parameter such as the currents consumed by the motors (16 to 21) driving the arm are periodically sampled and the position of the robot arm is periodically detected using position transducers (10 to 15). These parameters are compared with the corresponding parameters stored in a computer (1, 2 and 3) during preceding cycles of the robot arm and an emergency procedure is initiated when a parameter during the performance of a task varies excessively from the stored running average for the preceding performances of the same task. <IMAGE>

Title: Electrically reversible travel motor drive comprising a travel motor and at least one direction control contactor
Inventor: SCHUCKERT WOLFGANG
IPC: H02P7/03
Filed: 1982-11-24
Abstract: A reversible electric motor drive is provided, which comprises a motor 2, at least one direction control contactor 13, 14 and a monitoring circuit for detecting incorrect operation of the contactor. The motor is provided with two signal output terminals D1, D2, which carry different voltages in dependence on the sense of rotation. At least one additional signal output terminal e.g. 35 is connected to the contactor(s) and carries different voltages in dependence on the setting of the mechanism R1 for actuating the contactor(s). A comparator 45 detects whether the additional signal output terminal 35 delivers a signal which corresponds to or differs from the signals delivered by the signal output terminals D1, D2 connected to the motor. In response to this comparison a switching signal is generated, which acts at least to de-energize the motor when the signals do not correspond. <IMAGE>

Title: Fuel-injection device for an internal-combustion engine
Inventor: HOFKEN WILFRIED
IPC: F02M63/00
Filed: 1984-02-23
Abstract: A fuel-injection device for an internal-combustion engine comprises a pump (6, 7), an accumulator (11, 48) and a solenoid valve (16) in a fuel- injection line (17, 22) leading to an injection nozzle (19). The solenoid valve (16) is operated by a control device (31), such that while the valve is closed the pump (6, 7) pressurises fuel in a pump chamber (8) and thereby adjusts a pressure- loaded plunger (12), of the accumulator (11) whereas when the valve is opened fuel is delivered by the plunger (12) to the injection nozzle (19). The delivery stroke of the plunger (12) is detected by a measuring device (30) and the output signal of this measuring device (30) is conducted to the control device (31). The solenoid valve (16) is closed by a switching signal of the control device (31) when a required delivery stroke is reached. Thus the volume of the fuel injected can be exactly metered at any time. <IMAGE>
