Title: Fluid torque impact device
Inventor: KUNUTO KURISUCHIAN SHIEPUSU
IPC: B25B23/145
Filed: 1996-01-04
Abstract: PROBLEM TO BE SOLVED: To reduce a pressure gradient in a high pressure chamber by increasing the elasticity of trapped compressed fluid volume by a pressure responsive yielding means actuated only when the pressure difference between the high pressure chamber and a fluid chamber of a driving means is below a specified level. SOLUTION: When a threaded joint is reduced in speed to start a stroke of imparting specified tension, cam lobes 25, 26 press pistons 20, 21 inward to compress fluid volume trapped in a high pressure chamber 23 and buffering chambers 45, 46. Membranes 50 are bent outward by this pressure to increase the inertia of the trapped fluid volume. When the pressure in the high pressure chamber 23 reaches a specified level, the membranes 50 come in contact with surfaces 51 to stop the deformation of the membranes 50, and fluid on the rear side of the membranes 50 is discharged from openings 54 to a fluid chamber 12. When the pistons 20, 21 further move, the seal of cylinder bores 18, 19 is released, and the fluid flows out of the high pressure chamber 23.  The pressure in the high pressure chamber 23 is rapidly reduced to cut off torque transmission from a driving member 10 to an output shaft 16.

Title: Electrical connector crimping apparatus
Inventor: COLLIER JOHN COVELL
IPC: H01R43/052
Filed: 1962-01-03
Abstract: 948,869. Jointing by stamping. AMP Inc. Dec. 17, 1962 [Jan. 3, 1962; July 23, 1962], Nos. 210/62 and 28217/62. Heading B3Q. Apparatus for crimping electrical connectors arranged in strip form on to electrical conductors comprises a connector crimping station, means for feeding the leading connector of the strip to the station to be crimped to the conductor lying within the connector, means for feeding a length of wire to the station so that a portion of the wire lies within the leading connector to be crimped in side by side abutting relationship with the conductor and means for shearing the portion from the length of wire. Electrical connectors 3 arranged in end to end strip form 2 of a U cross-section are fed by a reciprocating finger 14 from a storage drum (not shown) along a plate 1 beneath a spring-loaded platform 4 on which a peripherally grooved or knurled wheel 7 is freely rotatable and which guides wire 11 from a spool 12 into the connector strip which is held therein by a resilient guide strip 10. The feed finger 14 is pivotally mounted on a reciprocable head 17 of e.g. a press ram and is spring biased in an anti-clockwise direction. During forward movement of the finger the tip 15 thereof engages a notch formed between the adjacent connectors to advance the strip with the wire held frictionally therein to a crimping station comprising movable and fixed shearing blades 19, 20, a crimping die 21 and an anvil 22 operated by a press ram (not shown) where prior to crimping the connector and shearing the assembly from the strip 2 the ends 24<SP>1</SP> of two conductors 24 are manually inserted between the arms of the leading connector and beside the leading portion of the wire 11. On the return stroke the finger is cammed over the strip against the spring 18. A solenoidoperated brake unit may be incorporated to prevent feeding of the wire. In a modification, the wire is fed over a platform on which is mounted a solenoid or pneumatically operated brake unit and through a hole in the tip of the finger from where it is deflected by a resilient member into the leading connectors. During the return stroke of the finger the solenoid is energized to clamp the wire to the platform and permit the finger to travel along the wire, and de-energized during the feed stroke to allow the wire to be advanced. Alternatively, the resilient member of the finger comprises a spring-loaded plate 56 located on a screw 57 retained by an adjustable plate 51, forward movement of the finger causes the plate 56 to grip the wire against the face 60 of the tip whilst during the return stroke the plate is retracted against the spring. The brake unit may be controlled by a programming unit (not shown) automatically or in a single cycle using a series of relay actuating stops on a motordriven carriage, e.g. pins in a circular plate in conjunction with the press operation.

Title: Jitter-free trigger control circuit
IPC: G01R13/32
Filed: 1973-01-03
Abstract: 1412213 Jitter free triggering circuits TEKTRONIX Inc 3 Jan 1973 [7 Jan 1972] 310/73 Heading H3P The production from a triggering input signal of a jitter-free output signal for triggering a circuit, e.g. a sweep generator, is enabled in response to the concurrent absence of an input signal and a hold-off signal generated by the triggered circuit, e.g. during the fly-back, and the passage of the triggering signal is delayed with respect to the production of a triggering enabling signal such that the triggering signal is effective only after the onset of the enabling signal. Jitter due to the presence of a triggering signal at the offset of the hold-off pulse and due to the presence of the enabling signal during the triggering signal is thus avoided. The sweep generator triggering circuit shown receives triggering signals TR and also receives hold-off signals HO generated by a monostable circuit triggered towards the end of the sweep to prevent triggering during the fly-back. If there is no triggering signal present at the offset of the hold-off pulse or when the triggering signal goes to zero a gate circuit 26, 42, 32 produces a "high" signal which triggers a bi-stable circuit 46, 50 to provide an enable signal at the input of a trigger signal producing gate 30. Accordingly the next triggering pulse TR provides a high level at the output of gate 30 and this triggers the bi-stable circuits 46, 50 and 34, 38, the former terminating the enabling signal and the latter providing the triggering output signal Q2 for the sweep generator. Pulse Q2 is applied to gate 26 to prevent retriggering during the sweep. Towards the end of the sweep this is replaced by the next hold-off signal HO which also serves to reset bi-stable circuit 34, 38 and terminate the output pulse Q2. By including a delay circuit it is arranged that if the offset of the input triggering pulse immediately follows the end of the hold-off pulse the enabling signal is produced before the triggering pulse reaches the trigger signal initiating jute 30.
