Title: Method of and apparatus for stripping a twisted pair of insulated  wires
IPC: H02G1/12
Filed: 1973-04-19
Abstract: 1379531 Stripping wires AMP Inc 19 April 1973 [31 May 1972 20 Sept 1972] 18977/73 Heading H2C A method of stripping the insulation from an end portion of a pair of helically-twisted wires comprises clamping the wires a chosen distance back from the portion to be stripped; transversely cutting through the insulation at the stripping position with blades; causing relative rotation between the blades and the clamp to untwist the portions of wires therebetween; and withdrawing the wires while the blades are still closed so as to strip off the insulation forward of the transverse cuts. Apparatus for so preparing a pair of wires comprises a stripping head, 2<SP>1</SP>, Figs. 7 and 9, having a cylindrical body 282 with radial slots 16, 16<SP>1</SP> carrying slidable blade holders 286, 286<SP>1</SP>, captive behind a face plate 284 secured to the rearward face of the body 282. Radical convergence of the blade holders 286, 286<SP>1</SP> causes the blades 308, 308<SP>1</SP> attached thereto to move from an open position through an intermediate position, Fig. 11, whereat they orient the wires, to a closed position, Fig. 9, whereat they cut through the insulation around most of the periphery of the wires without damaging the conductors. Radial slots 285 perpendicular to the slots 16, 16<SP>1</SP> permit the ejection of the severed ends of insulation by centrifugal force at a later stage in the operation. The angle 315, Fig. 11, between the portions 312 and 314 of the blade edge is preferably between 90 degrees and 120 degrees. An angle of 105 degrees is said to be particularly suitable. The stripping head 2<SP>1</SP>, fastened to a rotatable hollow shaft 88, Fig. 7, is actuated by spring- return levers 94, 94<SP>1</SP> engaging pins 30, 30<SP>1</SP> on the blade holders 286, 2861. The levers 94, 94<SP>1</SP> are caused to converge by cam rollers 106 pivoted in a collar 102 axially slidable on the shaft 88 when impelled by an hydraulically-driven clevis lever 108 engaging a peripheral groove 112 in the collar 102. A second hydraulic system 254 then drives a gear train 240, 122, 120 which rotates the shaft 88 together with the stripping head 2<SP>1</SP> sufficiently to untwist the portion of the wires between the stripping head and a cable clamp 82. A stop rod 126 axially adjustable within the hollow shaft 88 determines the length of insulation stripped. In a modification, Fig. 4, the head 2 carries blades 32, 32<SP>1</SP> each having a pair of semicircular edges 46, 48, 46<SP>1</SP>, 48<SP>1</SP> for cutting the insulation after the pins 40, 40<SP>1</SP> attached to the blade holders 18, 18<SP>1</SP> have converged to close the wire orienting members 58, 58<SP>1</SP> pivoted on the face plate 10, into the position shown.

Filed: 1974-05-01
Abstract: 1462415 Transistor switching circuits INTERNATIONAL BUSINESS MACHINES CORP 1 May 1974 [7 June 1973] 19026/74 Heading H3T A driver circuit comprises first and second devices 26, 27 connected to a common output line 10 so as to pass either a signal from line 23 or a signal from line 24 to the common output line 10 and means 25, 40 for enabling the line 10 to be discharged through the device 26. The line 10 is a word line associated with a memory matrix 11 comprising variable threshold FET's, e.g. T11, T12, and the input levels on lines 23, 24, 25 determine read, write and erase functions. The variable threshold FET's in the memory have a threshold of - 6 v. when not charged (logical 1) and a threshold of - 2 v. when charged (logical 0). Erase.-A + 20 v. signal is applied to line 25, a + 20 v. erase signal is applied to line 24 and 0 v. is applied to lines 23, 35, 36, 37. With these signals transistor 26 is turned off and transistor 27 is turned on charging line 10 to 20 v. and hence charging FET's T11, T12 (and similarly T21, T22) to produce the "0" level threshold of - 2 v. Line 24 is then returned to 0 v. and the line 10 (and 20) discharged to earth. Write 1 into T11.-A - 20 v. write signal is applied to line 23 and subsequently a - 20 v. signal is applied to line 25 to turn on transistor 26 and apply - 20 v. to line 10. Lines 34, 35 are of the selected cell T11 are maintained at 0 v. and lines 36, 37 of the non-selected cell T12 have a - 20 v. signal applied to them. Cell T 11 is thus discharged to its high threshold level of - 6 v., the other cells remaining charged. Line 23 then reverts to 0 v., and line 10 discharges through transistor 26. Read line 10.-A - 5 v. signal is applied to line 23, a - 6 v. signal is applied to lines 34, 36, a -20 v. signal is applied to line 25 and all other lines are held at 0 v. Transistor 26 turns on to apply -5 v. to line 10. This level is less than the threshold of any cells storing a "1" but greater than that of any cells storing a "0" so that cell T11 (carrying a "1") is not switched on, but cell T12 (carrying a "0") is switched on. Thus -5 v. is applied to line 37 indicating a "0" in cell T12, and line 35 remains at 0 v. indicating a "1" in cell T11. After read out, line 25 remains at -20 v. to discharge line 10 to earth again.

Abstract: 716,499. Dynamometers. MAWDSLEY'S, Ltd. Aug. 15, 1952 [Aug. 15, 1951], No. 19285/51. Class 106 (2). [Also in Group XXXVIII] Means for indicating the torque reaction of a rotary-absorption dynamometer comprises a weighing element in the form of one or more bars or beams acted on by the torque arm of the dynamometer, and means for translating the movements of deflection of the weighing element into an indication on an indicating element. As shown, the torque arm 1 of the dynamometer acts through interconnected members 9 and 10 on the centre of a metal beam 2 constituting a weighing element. A transmitter 8, arranged vertically above and adjustable with respect to the centre of the beam 2, converts the movements of the beam 2 into an electrical control of a dial type indicator 30. The dial of the indicating element 30 may be calibrated by suspending weights 7 of known value in a scale pan 6 connected to members 9 and 10. In order that positive and negative torques may be measured, for example the driving and motoring torque of an engine wherein the torque required to drive the engine is as low as 30 per cent of the torque which the engine develops at full load, a second torque arm 41 for applying a load to the beam 2 is provided. The torque arm 41 acts on one end of a pivoted lever 35 coupled at its other end 37 to the members 9 and 10. The ratio of the right-hand portion to the left-hand portion of the lever 35 may be such that even though the maximum value of the negative torque is small ,a maximum negative torque still gives a full scale deflection on the indicator 30. The beam 2 may be replaced by a cantilever or a torsion member. The loading of the dynamometer may be electrically produced.
