Title: Improvements in fabrics of synthetic fibres
Inventor: MESSINGER LESTER HUBERT
IPC: D06C11/00
Filed: 1959-12-29
Abstract: 896,267. Finishing fabrics. DU PONT DE NEMOURS & CO., E. I. Dec. 29, 1959, No. 44124/59. Drawings to Specification. Class 42 (1). A process for producing a fabric of improved aesthetics comprises confining a fabric containing a preponderance of filaments composed of a synthetic fibre-forming polymer having a melting-point above 250‹ F., which is wet with water at a temperature of 175‹ F. to 225‹ F., between confining structures, heating the fabric and water to a temperature of from 100‹ to 10 F. below the softening point of the synthetic polymer while maintaining sufficient pressure between the confining structures to maintain the fabric in the wet condition and thereafter immediately releasing the pressure from the fabric. In a preferred embodiment a fabric composed of continuous filaments of poly(hexamethylene adipamide) or poly(ethylene terephthalate) is wet with water and is passed at a speed of about 15 to 35 yards per minute between the two confining rollers of a conventional calender machine to exert a pressure on the fabric of from about 500 to 2000 1b. per inch of roll width, one of the rollers being a hard roughsurface roller heated to a temperature of from 100‹ to 10‹ F. below the softening-point of the synthetic polymer of the fabric and the other roller being an unheated compressible roller. In such a case, the pressure on the fabric is " immediately " released as the fabric emerges from the rollers. The fabric is padded in water at a temperature of 175‹ ‹ to 225‹ F. at a point as close to the nip of the rollers as is possible. Excess water is wrung out at the nip but enough water remains to keep the fabric wet. The rough surface of one roller allows the fabric to be compressed slightly below the surface at a number of points so that water is sealed therein across the nip of the rollers. The surface of the hard roller is preferably made of alloy steel, plastic, ceramic or coated metal and is preferably rust-proofed. The second roller is made of a compressible composition such as cotton, paper, wool, corn husk. Specification 578,079 is referred to.

Title: Credit accumulating arrangement
IPC: G07F5/22
Filed: 1969-09-12
Abstract: 1,254,510. Credit accumulating. SEEBURG CORP. OF DELAWARE. 12 Sept., 1969 [12 Sept., 1968], No. 45052/69. Headings G4A, G4D and G4V.  A credit totalling circuit comprises supply means 11, 13 for producing respective electric credit pulses which pulse respective inputs of a cascade of electronic full adder circuits FA, each circuit FA having a memory device FF connected between its set output and one input thereof. This is for use in a coin operated vending machine and a coin closes switch 11 or 13 which passes a pulse to one or more adder circuits FA, depending on the user's prior settings of the switches 19 to 33, by way of OR gates G0 to Gn. Each pulse enters the adder by way of input A and, if no pulse is stored there already, sets the output S. The output S is connected to the memory F which is a flip-flop, and a pulse on output S sets the flip-flop output Q (the adder input B) by means of a coin activated toggling input T activated by the trailing edge of the coin switch pulse which causes output Q to be set only after a delay when the pulse on input A has died away. A further pulse on A combined with the output on B produces a carry signal on output C and no signal on output S in the usual way. When a customer makes a purchase the price is subtracted, by complementing, from the accumulated credit by passing signals through the appropriate OR gates G0<SP>1</SP>-G<SP>1</SP>. A feedback line 43 is provided to carry round a one. Before subtraction occurs a gate of the gates G18 to G25 (Fig. 2, not shown) checks whether there is enough credit established. If the customer inserts coins totalling more than the credit capacity of the chain, an AND gate G11 (Fig. 4 not shown) would cause the chain to be " locked " and the credit held stationary, so that the chain does not go back to one again and the customer does not lose his established credit. A bonus crediting circuit is briefly described. Corresponding to that in Specification 1,254,509 the circuits are formed as an integrated circuit chip.

A transistor connected in the collector lead of an emitter follower transistor amplifier is saturated at normal current levels but at higher levels operates as a constant current source to prevent overloading. The figure shows a singleended push-pull amplifier comprising two amplifying transistors 11, 21 having their bases connected in parallel to input terminal 2 and their emitters feeding a common load 3. Protecting transistors 16 and 26 are normally saturated but if the amplifier transistor current rises excessively the base and emitter bias rises until the corresponding Zener diode breaks down and clamps the base voltage. Further rise in current brings the protecting transistor out of saturation and it operates as current limiting transistor. Diodes 10 and 20 provide a bias voltage between the bases and if they are similar to the emitter-base diodes and are located close thereto they will provide temperature compensation. Resistor 35 may advantageously be replaced by a constant current transistor.

Abstract: 479,468. Code telegraphy. STANDARD TELEPHONES & CABLES, Ltd., and TERRY, V. J. Aug. 7, 1936, No. 21814. [Class 40 (v)] Alternating-current signals comprising interruptions or phase-reversals are sent to line under the control of direct-current input signals which act upon a bridge containing rectifiers. The bridge is balanced when spacing current is applied to the rectifiers, but becomes unbalanced when marking current is applied to them. Alternating current from a source S is applied to a transmitting circuit T under the control of D.C. signals received at C, C. The rectifier bridges B1, B2, are oppositely poled, and when spacing current is being received at C, C the rectifiers B1 are in the highresistance condition while the rectifiers B2 are in the low-resistance condition. The bridges BR1, BR2 are balanced in these circumstances by a high resistance HR and low resistance LR respectively, and no A.C. passes from S to T. When marking current is received at C, C, however, the resistances of the rectifier bridges B1, B2 are changed and the bridges BR1, BR2 become unbalanced so that A.C. now passes from the source S to the transmission line T. In an arrangement, Fig. 2, in which there is a constant load on the geneiator S and a constant impedance towards the transmitting circuit T the alternating currents circulating in the meshes M1, M2 balance one another during the spacing condition, when the rectifiers B2 have low and the rectifiers Bl high resistance, but when marking current is received at the terminals C, C, the resistances of B1, B2 change so that the currents in meshes M1, M2 are reduced and increased respectively and a signal passes to the transmitting line T. In a modification, Fig. 3 (not shown), the parts PR, SR, C2 are omitted and in that case alternating current passes continuously to the line T, but its phase is reversed by the change from spacing to marking.
