Patent CH-630466-A5 (CH)
Title: Current measuring arrangement
Inventor: SCHOETZAU PHYS HANS-JOERG DR
IPC: G01R15/22
Filed: 1978-08-31
Abstract: In this current measuring arrangement, the conductor (1) carrying the current to be measured exhibits a constriction (2). A magnetic-field-dependent element (3) such as, for example, a Rogovski coil or a semiconductor, is attached around the constriction where a relatively high current-proportional magnetic field prevails. The measurement-value converter (10) converting the measurement values occurring at the connections of the magnetic-field-dependent element into an optical signal is accommodated in a hollow space (8) which is free of electromagnet fields and is arranged directly adjacently to the constriction. In the same hollow space, the batteries (11) used for supplying the measurement-value converter with current are inserted. An optical waveguide (13) connects the measurement-value converter (10) to an output unit which generates electrical output signals from the optical signals. <IMAGE>

Abstract: 1515217 Door closers VEREINIGTE BAUBESCHLAGFABRIKEN GRETSCH & CO GmbH 19 July 1976 [7 Aug 1975] 29919/76 Heading E2M A door closer includes a spindle 2 protruding from a housing 1, a closer spring 7 and, laterally beside the spring 7, a piston 9 and cylinder 6 of a damper 8, the spindle 2 carrying two cam discs 3, 4 which act respectively on the spring 7 and damper 8 on rotation of the spindle 2, in each case through a rocker arm 13, 25. Each rocker arm 13, 25 abuts through a roller 17, 28 on the cam disc 3, 4 and through another roller 12, 29 on the spring 7 or damper 8, the rocker arms 13, 25 being mounted approximately opposite to one another at 14, 26 in the housing 1. The longitudinal axes 19, 31 of the spring 7 and damper 8 remain fixed relative to the housing 1. Preferably as shown, the spring 7 is arranged parallel to but higher than the damper 8 in the housing 1. The spring 7 is guided in a cylinder 5 and surrounds and abuts against a bolt 11 which carries the roller 12. The run-off face 18 of the arm 13 is so curved that its tangential surface at its contact with the roller 12 is always perpendicular to the axis 19. The roller 29 is mounted in a recess 35 of the rocker arm 25 and abuts on a run-off face 30 provided on an extension of the piston 9.

Title: Machine for generating a surface on a component
Inventor: HOOKER DERRELL C
IPC: B23Q35/10
Filed: 1976-08-19
Abstract: A lathe for generating a spherical or aspherical surface on a lens (W) comprises a chuck (mandrel) (22) supporting the lens (W), so that it revolves about its axis. A saddle (29) carries a cutting tool (T) into a position in which the latter projects in the direction of the lens (W). The saddle (29) is placed on the upper surface of a slide (28) on which it pivots by virtue of a pivot (30). The saddle (29) is rotated about the axis of the pivot (30) by a conventional device to make it oscillate progressively about this axis. A slide (35) supports the tool (T), so that it freely performs a floating movement forwards and backwards whilst being stressed elastically towards the front by a spring (36) into contact with the lens (W). A device supporting a cam (50) independently of the saddle (29) allows an adjustment in the direction of rotation of the lens (W) either perpendicularly to the latter or in both directions. <IMAGE>

Title: Safety belt locking device in a vehicle
Inventor: DUCOMMUN GEORGES
IPC: B60R22/48
Filed: 1976-08-23
Abstract: In the case of a locking device for a three-point safety belt (7) having a lock and a locking tongue (6), the belt can be functionally connected to the corresponding door (3) in such a way that the door is secured by the belt. There are also means (12, 14) present which ensure that the door cannot be fully closed from inside until the locking tongue has been inserted into the belt lock. Provision can also be made for opening of the door from the inside to be impossible while the locking tongue is still inserted in the belt lock. This ensures on the one hand that the driver puts on the belt(s) before starting to drive and on the other hand that the door is secured on the user side. <IMAGE>

Abstract: 1371181 Lapping PAYNE PRODUCTS INTERNATIONAL Ltd 26 Oct 1972 [3 Sept 1971] 41126/71 Heading B3D A lapping machine comprises a rotary lap plate 2, conditioning rings 11 maintained on the plate by bracket arms 7 in the form of yokes, a supporting structure 5 rotatable concentrically about the press of the lap plate and providing a mounting for the bracket arms, a loading table 12 reversably movable to a location adjacent the lap plate, the loading table having a flat loading surface 25 and being provided with means 14, 21 so that its surface may be raised and lowered to a position slightly higher, and a position slightly lower than the lap plate at its adjacent location, and means for rotating the supporting structure over successive angular distances of 360 degrees/n, where n is the number of conditioning rings. The supporting structure consists of a base ring 3 which is mounted concentrically to the lap plate and has three upstanding struts 4 secured to a triangular structure 5. Columns 6 extend downwardly from the structure 5 and carry the yokes 7 which have rollers for engaging the conditioning rings. Pneumatic cylinders 8 are also carried by the structure for moving disc-shaped weights 10 into and out of engagement with workpieces located within the conditioning rings. The base ring 3 is indexable by a chain drive to bring each conditioning ring successively adjacent the loading table 12 which is movable between an inoperative position and a position adjacent the lap-plate by a ram 23, the table having slotted brackets 22 on its lower side engaged by pins 15 on parallel links 16 pivoted to the base of the machine; the slots enable the table to move horizontal during the final movement into its operative position and fingers 14 on the table to rest on the lap plate and position the table slightly below the plate to facilitate sliding of a conditioning ring with finished workpieces on to the table. As a conditioning ring with workpieces to be lapped is moved towards the lap plate, a switch is actuated so that pneumatic rams 19 rock levers 20 about pivots on the fingers 14 to move plungers 21 into engagement with the lap plate whereby the table 12 is raised slightly above the plate to facilitate movement of the conditioning ring and workpieces on to the plate. After one third of the lapping time, the procedure is repeated to change the next conditioning ring, and so on.

Title: Locking device for ends of thread on bobbin - has rings fitting over bosses whose slit ends receive thread
IPC: A01K97/06
Filed: 1973-05-11
Granted: 1974-12-06
Abstract: This device may be used for cotton ends, or in stowing fish hooks onto a reel. The reel or bobbin may be in any material but is fitted with any convenient number of bosses. Each boss has a slit across it which will accept the end of the thread. The slot is wider than the thread, so that it can rest loosely in the slot. A plastic ring can be forced over the boss, thus jamming the thread end on the bobbin. This way there is no need to stretch, the thread in order to wedge it. The hooks engage the other edge of the reel or bobbin between bosses of a second row.
