Title: Arc welding process - involves vibrating the free end of a consumable electrode, within the space between two metal workpieces to be welded
Inventor: ROEN RICHARD ALAN
IPC: B23K9/30
Filed: 1979-07-23
Abstract: A weld is formed in a space between the walls of two metal pieces to be welded, the process involving moving a consumable electrode in a torch and subsequently into the space while the two workpieces and the welding torch are moved relative to each other so that the torch is moved along or reciprocated within the space. A sufficiently high voltage is applied between the workpieces and the consumable electrode to form an arc to melt the electrode and at least a portion of the walls of the workpieces, the electrode reciprocating across the space. The reciprocation frequency is >=6H2, during welding, the free end of the electrode is located within the space while at the ends of each reciprocating cycle of the electrode, an impact force is applied to interrupt the electrode movement towards the wall in the direction of which it has moved before the application of the force and immediately after the application of the impact force, the electrode is moved away from the wall to approach the opposite wall so that the molten metal at the free end of the electrode is projected against the wall. The process is suitable for use in nuclear reactor pipes since the weld obtd. is spread out and the penetration is not excessively deep. The process is advantageous for surface hardening since penetration is slight.

Patent FR-2447065-A1 (FR)
IPC: G07F1/04
Filed: 1980-01-16
Abstract: The aim of the invention is to provide a hinge mechanism for a coin testing mechanism which permits adequate separation of two plates, even close to the hinge axis, in conditions where the separation of the plates remote from the hinge axis must be limited. The two plates 12 and 13 are coupled by a hinge pin 19 which passes through slots 21 in lugs 22 on the plate 13 and holes in lugs 20 on the plate 12. A coil spring 23 is disposed around the hinge pin 19 and has its free ends secured to a cantilever leaf spring 28 secured to the plate 13. The slots 21 extend perpendicular to the plate 13 and the springs 23 and 28 co-operate to hold the hinge pin 19 in the bottom of the slots 21. The coil spring has a central loop 24 which bears against the edge of the plate 12 and thus serves to bias the two plates together about the hinge axis. A lever 31 pivoted on the plate 13 carries a cam surface 32 which co-operates with a cam follower surface 35 on the plate 12 so that when the lever is actuated the plates are forced progressively apart by the cam surface riding up the cam follower surface. The coil spring 23 initially allows the plate 12 to pivot about the hinge axis away from the plate 13 but eventually plate 12 strikes an abutment 38 which prevents further rotation of the plate. Further movement of the cam surface up the cam follower surface causes the leaf spring 28 to flex and allow separation of the plates along the edges adjacent the hinge pin 19.

Title: Pushbutton electric switch - has thrust action exerted by effect of transfer and simultaneous pivoting of two pressure members constantly engaged with movable contacts
Inventor: BICCOLINI VINCENZO
IPC: H01H5/04
Filed: 1980-02-25
Abstract: The push-button electric switch includes one or more pivotally displaceable contacts (6,6') for each push-button (A,B). Reversal of the position of a displaceable contact or of the displaceable contacts of each push-button in a group is obtained by a thrust action on one part or the other about the pivotal point (5,5') of the displaceable contact or contacts (6,6'). The thrust action is exerted by effect of a transfer and simultaneous pivoting of at least two pressure members (9,9') in constant engagement with the displaceable contact (5). The transfer and simultaneous angular rotation of the pressing members (9,9') are derived from the translatory movement of the key-carrying slider (7).

Title: Fluid or gas pressure indication and control - uses piston with two different sized areas acting on regulator valve or indicator
IPC: G01L7/16
Filed: 1980-05-28
Abstract: The method is for indication and/or regulation of fluid or gas pressure, and uses a mechanism comprising a piston (7) which can advance in a housing body (1) and which has two areas (7,7') working towards each other. These piston areas are subject to the pressure from the medium being handled, and are different in size. A mechanical load force acts on the smaller of the piston surfaces, and both surfaces then perform a common advance movement when the medium pressure exceeds a preset limit value. They can act on a flow-regulating valve and/or give an indication of the medium pressure.

Title: Stop valve actuated by fluid pressure - has double bellows and double chambered valve body with fluid pressure controlled by pilot valve
Inventor: GUTIERREZ JAVIER
IPC: F16K31/385
Filed: 1980-10-20
Abstract: The stop valve (10) comprises an upper valve chamber (12) and a lower chamber (14). The upper chamber houses an actuator (40) connected to the valve stem (32) carrying the valve disc (28). A non-conductive seating (36) serves to isolate the upper and lower chambers. In the closed position the valve disc (28) rests on the seat (26) so that upstream fluid pressure exists in the inner chamber (56) which is sealed with the bellows (50). The pilot valve is positioned so that the upstream pressure also exists in the outer chamber and acts on the larger area of the piston maintaining the valve closed. To open the valve the pilot valve is operated so as to release the pressure, in the outer chamber, to atmospheres. The resultant upward force on the piston opens the valve. Reversing the position of the pilot valve closed the stop valve.
