Title: A device for the simultaneous braking of moving yarns and the catching of slubs therein
IPC: B65H63/06
Filed: 1959-02-02
Abstract: 894,057. Braking and tensioning yarns and warps; slub catchers, stop-motions. ALGEMENE KUNSTZIJDE UNIE N.V. Feb. 2, 1959 [Feb. 4, 1958], No. 3672/59. Classes 120(2) and 142(1) A device for braking moving yarns and simultaneously catching slubs comprises two bodies with opposed faces defining a slit between them, the bodies being relatively movable to vary the width of the slit and being urged towards one another to reduce the width of the slit to grip the thread, stop means being provided to limit the movement of the bodies away from one another and hence to limit the maximum width of the slit to less than the size of a slub to be caught. In Fig. 1, a plate 2, spring-ringed at 5 is disposed within the U-shaped ends of a member 3; in Fig. 4, a plug 11 fits loosely in a tubular sleeve 10 provided with a slot 12 in which a spring is provided: in both forms a stop is provided to stop the inner member falling out of the outer one. The spring urging the points together may be replaced by magnetic force, or by gravity, the device being then disposed so that one of the two co-operating parts tends to bear against the other, in which case the device may be on a bracket so that it may be tilted to vary the braking-force. To provide slits of different widths, the plate 6 is replaceable by thicker or thinner plates or the plate and the U-shaped ends of member 3 may be wedge-shaped. The outer-member may be connected, e.g. at 7 to a stop-motion so that the associated machine is stopped when a slub causes the plate 3 to rise.

Title: Improvements in or relating to phonograph record players
IPC: G11B17/24
Filed: 1954-02-09
Abstract: 746,116. Magazine gramophones. ACKER, N. K. Feb. 9, 1954 [Feb. 10, 1953], No. 3741/54. Class 40(2 In a magazine gramophone records are supported edgeways radially on a rotatable horizontal plate 3 and positioned so that the horizontal diameter of any record 4 on one side of the plate passes between two o records on the opposite side of the plate, mechanism being provided for lifting a record into an elevated position over the centre of the magazine to a horizontal turning axis for playing the record. The particular record, and side to be played, is selected by means of a rotatable dial 18 carrying a plunger 17 which when operated displaces one of a number of pins 15 on a disc 16. There are twice as many pins 15 as there are records, thus each pin corresponds to a side of a record. The insertion of a coin in the machine sets the plate 3 in motion until arrested by the raised pin 15 which intercepts a tongue 20 on a, bracket 21 mounted for limited movement on a plate 23 secured to the plate 3. The bracket 21 is displaced against the tension of a spring 24, and a switch 26 is thereby operated to reverse the direction of rotation of the plate 3 which is almost immediately stopped and locked by a spring-loaded pawl 27 intercepting one of the pins 15. At the same time, a spring 19 is held back from the raised pin 15 which thereupon drops to its normal position. Also at the same time, a motor 28 is started so that a gear 31 on the motor shaft 37 drives a wheel counterclockwise to unwind cords 34 connected to lifting arms 7 which are then moved inwardly and upwardly under the influence of springs 35, to roll one of the records 4 up the inclined plane 9, a right-hand or left-hand record being lifted according to whether side 4a or 4b, respectively, of the record is to be played. The rising record moves a movable flap 11 to a position such that the record when descending again is returned to the same position on the plate 3 from which it came. When the record has been raised to the position shown in Fig. 3, a centreing member 38 is driven forward on a spiral track on the motor shaft 37, at the same time releasing gear 31 by the disengagement of teeth 41 and 31a, so that cords 34 cease to unwind and the member 38 centres the record on turntable 10, both of which then rotate owing to the engagement of a pin 47 with a groove 48. The stylus of a reproducer on an arm 44 spring-loaded against a member 50 is thus brought into contact with the start of the record. When the record has been played, the reproducer arm 44, upon reaching a certain position operates contacts which reverse the direction of the motor and causes all the aforesaid operations to be reversed so that the record is restored to the magazine, the pick-up arm under the influence of a light spring pressure being returned to its initial position.

Abstract: 1,213,382. Electric analogue multiplying. INTERNATIONAL BUSINESS MACHINES CORP. 25 Jan., 1968 [25 Jan., 1967], No. 3910/68. Heading G4G. [Also in Division H3] Analogue multiplication circuit (Fig. 3) receives a voltage Ve over series resistance to an input of amplifier A 1  energizing the gate of field effect transistor T 1 , operating as a resistance variable with Ve in series with source load resistance R 4 ; whose drain and source are D.C. energized from supply Œ U with negative feedback from source to amplifier input; the source output V o  being connected to an input of amplifier A 2  and the output of amplifier A 1  being applied to a second opposed input over variable resistance R 8 . Negative feedback is provided over R 6  and the output excites the gate of a similarly operating field effect transistor T 2  whose drain and source are energized from supply ŒV in series with variable source load resistance R 10  from which negative feedback is applied to the second input of A 2 . It is shown that the output voltage V s  across R 10  is linearly proportional to Ve.V/U; R 8 , R 10  being adjustable for zero. In a modification (Fig. 6, not shown) the drain/source circuit of a field effect transistor is energized from a supply of Œ (U+V) wherein U is D.C. and V is A.C. voltage in series with a load resistance; the gate is energized from an amplifier to which an input Ve is applied over a series resistance, together with feedback of the output voltage V s  across the load resistance over a low pass T network incorporating series reistance R 14 , R 15  and shunt capacitance C; it is shown that V s  = KV e V.
