Patent GB-1343307-A (GB)
Title: Feedback clipper
IPC: H03G11/00
Filed: 1971-04-20
Abstract: 1343307 Clipping circuit RCA CORPORATION 20 April 1971 [22 April 1970] 10066/71 Heading H3T In a clipping circuit comprising an amplifier with negative feed back and a semi-conductor clipping device, non-linearity of the output signal, as it approaches a clipping level, is reduced by coupling the device to the feed back path to alter the gain of the amplifier. A circuit for clipping a video signal at the black level includes an amplifier 14, 16 and a clipping diode in the form of the base-emitter path of a transistor 21. A second transistor 23 provides temperature compensation of the clipping level at 20 set by potentiometer 24. As the base-emitter path of transistor 21 conducts, it shunts the feed back path 19, 18, 17 to increase the gain of the amplifier. This produces a sharper "knee" to the clipped waveform.

Title: Attachment for a machine for abrasive finishing of contoured or profiled surfaces
IPC: B24B41/06
Filed: 1962-03-16
Abstract: 954,151. Grinding. F. W. ARMYTAGE. March 18, 1963 [March 16, 1962], No. 10070/62. Heading B3D. An attachment for a honing or like machine is arranged to be secured over the worktable of the machine and has workholding means 1 rotatable about a horizontal axis and oscillatable horizontally in a path lying substantially in the general plane of rotation so that the workpiece can be rotated and/or oscillated in contact with the honing tool with or without reciprocation of the latter. The machine may be of the type described in Specification 882,859 having a honing head which is reciprocated vertically relative to a worktable and carries an hydraulic tracer valve mechanism actuated by movement of the tool to maintain the latter automatically in contact with the workpiece at a substantially constant pressure. The attachment has a body part 4 which is placed on the worktable of the machine so that a disc 10 can be driven by a magnetic rotary worktable. The disc 10 is connected by a pulley 9 and a belt 7, which runs around jockey pulleys 8, to a pulley 6 on a spindle 2 for the workholding means 1. The spindle is rotatable in bearings in an arm 3 which is mounted by a pivot 5 in the part 4 and is oscillatable by a pin 11 on the disc 10 connected by a crank mechanism to an arm 25 on the pivot 5. The crank mechanism consists of an arm 12 connected to the pin 11 and by a pivot 13 and an assembly 14 rockable about a pivot 15 on a lever 16 at one end mounted by a pivot 17 on the part 4 and at the other end connected to a screw-and-nut adjusting mechanism 18, 19. The assembly 14 has a nut 21 which is axially movable of the assembly by a screw 22 and is connected by a lever 24 to the arm 25. Adjustment of the nut 21 varies the amplitude of oscillation of the indle 2 while adjustment of the mechanism 18, 19 varies the mean position of the oscillation. The attachment may have an arm 26 connected to a vertical pivot 27 on the machine work-table whereby the attachment can be swung between an inoperative position and an operative position above the magnetic rotary work-table, a locking pin 28 engaging one of the vertical pillars of the machine in the latter position. A screw 32 provides means for lowering the disc 10 into engagement with the rotary work-table. The pulley 6 is split and can be opened to disengage the belt-drive to the workholding means which can then be indexed into successive positions by a plate 30 and plunger 31. In honing circular areas, the spindle 2 is rotated without oscillation while the tool is reciprocated vertically. For honing a square area, the spindle is oscillated but not rotated while the tool is vertically reciprocated. A hexagonal area would be honed likewise with the area indexed into three successive positions.

Filed: 1945-04-24
Abstract: 591,068. Two-part couplings. ANNAN, R., and FEARN, E. J. April 24, 1945, No. 10309. [Class 38 (i)] In a plug-and-socket coupling, the tubular socket a has a spring wire locking member f secured in a recess in the open end thereof and comprising a central loop g and two ears h, the loop being spread by the initial insertion of a plug pin b into the socket to cause the ears to project from slots i in the wall of the latter until the loop engages an annular groove w in the pin when the latter has been completely inserted, whereupon the ears retract thereby allowing an insulating sleeve m on the plug to slide over the slots i under the influence of a spring t. Lateral movement of the locking member and hence withdrawal of the plug is thus prevented until the sleeve m is retracted to uncover the slots i. The sleeve has limiting sliding movement between a washer v on the plug pin and a hexagonal metal bush l which it encloses and through which the plug pin is slid, the looped end p of the pin being held captive against one enlarged end of the bore of the bush by an insulating cap q screwed on to the threaded exterior of the said end of the bush. The cap q also clamps a lead wire in the looped end of the plug pin.

Title: Improvements in centrifugal clutches
IPC: F16D43/22
Filed: 1936-04-08
Abstract: 456,710. Friction clutches. SCHNEIDER & CIE, and FIEUX, J., 42, Rue d'Anjou, Paris. April 8, 1936, No. 10408. Convention date, April 16, 1935. [Class 80 (ii)] A slipping centrifugal clutch comprises an internal helix 22, Figs. 1 and 2, engageable with a drum 21 secured to the driven shaft 19, one end of the coil being connected at 23 to a disc 2 secured on the driving shaft 1 and the other end being connected at 24 to a freelymounted member comprising a hub 11, disc 12, and drum 13. Weighted arms 7, 8 are pivotally mounted on the disc 2 and hub 11 respectively and are pivoted together in pairs by pins 6. Centrifugal action thus tends to expand the coil into engagement with the drum 21, while increase of driving torque tends to contract the coil. A number of springs 16 are arranged between pairs of abutments 17, 18 on the disc 2, a finger 15 formed on the drum 13 projecting between each pair of abutments as shown in Fig. 1, wherein the clutch is shown in disengaged condition with the driving shaft at rest. With the driving shaft rotating idly, the coil contracts on to the drum 13. The springs act to oppose the centrifugal action so as to render the clutch inoperative below a predetermined speed, and also act in the other direction to absorb shocks upon disengagement. In the form shown in Fig. 7, twin coils 22, 25 which are angularly displaced by 180‹, are provided, and the abutments 17, 18 for the springs 16 are formed on the member 12 while the fingers 15 project from a disc 2<1> rotating with the disc 2 ; further, the drum 21 is connected to the shaft 19 by radially-flexible arms 201.
