Title: An Automatic Cop Supplying Method and Apparatus
IPC: B65H67/02
Filed: 1966-10-17
Abstract: 1,158,707. Feeding cops to, and donning cops in winding machines. MURATA MACHINERY CO. Ltd. 17 Oct., 1966 [20 Oct., 1965; 27 Nov., 1965; 22 Feb., 1966], No. 46410/66. Headings D1F and D1J. An automatic method for supplying cops to an automatic winding machine comprising feeding cops 3 in containers 4 to a point c where the cops are individually transferred to cop carriers 58 which move along an endless path, retrieving a yarn end from each cop along the path and joining it to the yarn end of a package being wound on a winding station 5, and feeding each cop to the appropriate winding station. The cop containers 4 transferred from a spinning machine by a conveyor pass along conduit 40 to rotating disc 12 which feeds the containers to a pair of vertically spaced horizontal plates 32 which have four grooves 31 spaced around their periphery. The cop carriers 58 are mounted on top and bottom rails and are driven through a friction drive by belt 56. Plates 32 are also driven through a friction drive. Both drives are set in operation by the passage of a winding station 5. Both the plates 32 and carriers 58 are normally prevented from moving by stoppers. Solenoids actuated by the passage of a winding station momentarily retract the stoppers so that an empty cop carrier 58 moves into the position below point c while plates 32 move through a quarter turn so that a cop container in a groove 31 moves to point c. At point c a cop falls through a chute into the carrier 58. The empty containers 4 are passed along a conduit 41 to a conveyor which returns the containers to a spinning machine. At position h the top of each cop is guided between a pair of rotating rollers which have radially projecting blades of polyurethane resin which loosen a tip bunch wound at the top of each cop. The loosening may be assisted by rotating the cop by a belt. The loosened yarn end is sucked into pipe 124. The bottom rail adjacent pulley 50 is obliquely positioned to cause the carriers 58 to become inclined and be aligned in position i with the cop mounting peg of a winding station 5. At position i a stopper prevents movement of a carrier till a winding station is positioned opposite threto. At position the two yarn ends are knotted together, while at position k the cam rail holding the trap door of the carrier shut is inclined away front the bottom of the carrier allowing the door to open and the cop to fall onto the peg.

Title: Transformerless transistorized power amplifier
Inventor: STONE John
IPC: H03F3/26
Filed: 1961-12-29
Abstract: 1,004,515. Transistor amplifying circuits. FRANKLIN INSTITUTE OF THE STATE OF PENNSYLVANIA. Dec. 29, 1961, No. 46582/61. Heading H3T. A push-pull amplifier comprises a pair of bridge networks 10, 11 as described in Specification 1,004,514, each network containing two transistors 12, 13 or 12<SP>1</SP>, 13<SP>1</SP> of a first conductivity type with their emitter collector paths connected in series, a bridging transistor 18 or 18<SP>1</SP> of opposite conductivity type for helping to maintain the voltage drop across the series transistors in a predetermined ratio determined by series resistors 14, 15 or 14<SP>1</SP>, 151 and a fourth transistor 19 or 19<SP>1</SP> of the same conductivity type as the series connected transistors connected as shown in Fig. 1. Input signals are applied to terminals 20, 20<SP>1</SP> and the load 22 is connected between output terminals 21, 21<SP>1</SP>. Resistors 15, 15<SP>1</SP> are each broken down into two separate resistors 16, 17 and 16<SP>1</SP>, 17<SP>1</SP> and when resistors 14, 16 in one bridge circuit are equal to resistors 14<SP>1</SP>, 16<SP>1</SP> in the other and the bridges are balanced no current flows through the load resistor 22. If a signal is applied to the input terminals such that point P 1  is made more positive and point P 1 <SP>1</SP> correspondingly more negative the base of transistor 18 becomes more positive, resulting in this transistor becoming more conductive and consequently the base of transistor 12 becoming more negative such that current flows through transistor 12 and the load until this transistor is saturated. The positive input signal applied to the base of transistor 19 tends to make this transistor less conductive and since the emitter of this transistor is connected to the base of transistor 13 this transistor will also become less conductive. In bridge 11 the point P 1 <SP>1</SP> becomes more negative causing transistor 18<SP>1</SP> to become less conducting and subsequently the base of transistor 12<SP>1</SP> to become more positive resulting in this latter transistor having a higher impedance. Since point P 2 <SP>1</SP> is connected to P 1 <SP>1</SP> through a relatively small resistor 17<SP>1</SP>, point P 2 <SP>1</SP> will tend to become as much less positive as P 1 <SP>1</SP> resulting in transistor 19<SP>1</SP> conducting more and the base of transistor 13<SP>1</SP> becoming more negative and its impedance being lowered. A voltage is therefore developed between the points P 3 , P 3 <SP>1</SP> proportional to the applied input signal. By positioning resistors 17, 171 between the points P 1 , P 2  the input/output characteristics of the circuit for applied positive and negative input signals are displaced slightly with respect to each other, Fig. 2 (not shown) so that the combined characteristic is substantially linear throughout its length despite the curvature near the origin of the two partial characteristics. The input signal may be applied to either points P 1  or P 1 <SP>1</SP> separately.

Abstract: 1386522 Inertia switches; switch contacts GENERAL MOTORS CORP 12 Oct 1972 [22 Oct 1971] 47095/72 Heading H1N A crash sensor 10 is supported on the front bumper of a motor vehicle which impacts on an obstacle and decelerates before the occupant compartment, the sensor being responsive to a change in velocity greater than a predetermined value to inflate a cushion in the occupant compartment, and comprising a mass 44 constrained against movement. Mass 44 reaches its actuating position only after experiencing the total change in velocity of the bumper during the deceleration time period of the bumper. Mass 44 is spool-shaped and slides in an insulating housing until its two end-plates 46 engage over spring contacts 60 to bridge them, mass 44 being constrained against movement by springs 52 gripping the centre axle 48 of the spool, and once end-plates 46 slide over contacts 60, the resilience of contacts 60 grips end-plates 46 to prevent return of mass 44 by springs 52.

The pusher head is integral with a pair of rearwardly extending support plates 60, each of which has a series of vertically spaced apertures 62 formed therein by which the head 12 is adjustably secured to a pair of guide rods 64 with bolts 66. The scoop 20 has a recessed base portion 86 and three sides 88, including an upwardly inclined bottom side and flared vertical sides. Scoop 20 is rigidly secured to a shaft 90 by means of a pair of brackets 92, the shaft being rotatably mounted in bearings 94 which are secured to a support plate 96 rigidly mounted on the furnace 18. The depth of insertion of the scoop into the dross is adjustable by means of a series of vertically aligned holes 98 formed on the sides of the scoop which receive bolts 100 for securing the scoop to the brackets 92. A pneumatic ram 102 is pivotally mounted in a support channel 97 and has a rod 104 which is operatively connected to shaft 90 by a crank 106. actuation of the ram 102 causes the scoop 20 to pivot about the shaft 90 to allow dross pushed into the scoop by the pusher head 12 to be discharged through the open side 89 of the scoop.
