Title: Analog/digital processing techniques
Inventor: WIDENOR MALCOLM D
IPC: G05D3/20
Filed: 1968-02-20
Abstract: 1,212,234. Analogue/digital converters. NORTH ATLANTIC INDUSTRIES Inc. 20 Feb., 1968 [11 May, 1967], No. 8112/68. Heading G4H. In an analogue to digital converter, a signal representing the analogue error signal from a comparator 14 comparing the analogue input signal with a feedback signal is integrated by an integrator 22 controlled by clock pulses. In the embodiment of Fig. 1 in which either the analogue input is synchro data when a bridge comparator is used or the comparator is a resolver positioned by a shaft angle input, the A.C. error signal from the comparator after amplification and multiplication by a fixed reference signal is integrated either for a halfcycle or an integral number of cycles of the A.C. signal, the integrated signal being fed to a decision circuit 25 which controls the digital data fed from a control and adjust system 12 to a digital/analogue converter 13, the output from which is compared with the input signal. In the embodiment of Fig. 3, the integrated error signal is fed to a voltage/frequency converter 31, the output from which controls a counter in the control and adjust system 12. The converter 31 may be polarity sensitive or separate polarity sensitive circuits may control the direction of count. When the error signal falls below the threshold of counter 31 clock pulses may be fed to the control system by a switch 32. In a modification (Fig. 4, not shown), the integrated signal is temporarily stored to give a continuous signal to the converter 31.

Title: Improved manufacture of combustible briquets
IPC: C10L5/14
Filed: 1925-03-26
Abstract: 244,624. Welton, P. E. March 26, 1925. Composition fuel.-In the manufacture of tubular briquettes coal culm is mixed with a temporary binder of fine coal dust and water and a binder to take effect after the briquettes are baked, comprising dry sulphite liquor bye-product and a petroleum product such as oil refining residue wax. The mixture is then moulded preferably by an extrusion press which forms a continuous tube from which short lengths are broken off. The briquettes are baked at e.g. 275‹ F. for about 15 minutes. In an example, 100 parts of crushed coal are mixed with two parts of sulphite liquor, 3 parts of oil refinexy residue wax, and 10 parts of water. Specification 244,623 is referred to.

Abstract: 900,109. Flock-coated fabric. MANUFACTURE DE FEUTRES DE MOUZONANCIENS ETABLISSEMENTS R. SOMMER & SES FILS. March 10, 1959 [March 11, 1958], No. 8189/59. Class 140. A flock-coated fabric comprising a support formed of woven material or felt having flocked fibres on one face interlocked and united with the support by an adhesive substance surrounding the base of the flocked fibres and portions of the fibres of the support having interstices therein between the fibres for the passage of air, is formed by coating the support with foamed latex 5, projecting fibres 6 upon said latex, causing the foamed latex to collapse by bursting the air bubbles therein to produce a homogeneous fluid mass 7 which is distributed by capillarity about the flocked fibres and the fibres 3, 4 of the support thereby uniting the fibres and allowing the formation of interstices, and thereafter vulcanizing the whole. The latex may be of natural or synthetic rubber. The flocked fibres may be relatively long, for example, of the order of 4 millimetres or more. The rate of foam collapse may be adjusted by controlled addition of a stabilizer or wetting agent to the foam according to the nature and previous treatments of the fibres of the support.

Title: Improvements in or relating to sewing machines
IPC: D05B1/04
Filed: 1937-01-12
Abstract: 485,917. Sewing-machines. STEVENS. A. H. (Naftali Slip Stitching Process, Inc.) Jan. 12, 1937, No. 8784 /38. Divided out of 488,712. [Class 112] In a running-stitch machine with a doublepointed to-and-fro needle, means are provided to hold the thread to prevent its entanglement. The double-pointed needle 52 is alternately gripped by reciprocating upper and lower reciprocating needle bars 50, 51 operated by levers 53, 54 connected to the plate 41 which is moved by rollers 39 following a cam track in a wheel 38 rotated on the shaft 33 by gears 35, 36, belt 31 and motor M. Spring-pressed arms 81, 86 pivoted to brackets on the frame of the upper needle bar embrace the needle when held in the upper needle bar, to maintain the threads in proper alignment for threading the needle and prevent entanglement when the needle bar is in its uppermost position. When the needle bar moves downwards, its wedge-ended chuck 90 separates the spring arms to release the thread for effective use. When the needle is connected to the lower needle bar, the thread is held by arms on a forked member 96 which straddle and press on opposite sides of the needle. These arms are operated by a link 93 having a pin 95 travelling in a slot 92 in a link 91 on the rocker arm 54. Co-operating with the needle is a member 105 which is oscillated about its pivot 106, Fig. 5, at predetermined intervals to pull the loose end of the thread to form a loop, by the aid of its extension 116. The member 105 is operated by a link 109 connected to a link 108 operated by a shaft 107. The loose end of the thread is thus prevented from being entangled or broken when the needle is changing needle bars, by the production of this loop. The thread is pulled out of the fabric by a puller 120 travelling round a grooved drum 121. The puller is mounted on an arm 125 pivoted at the axis of the drum at 126, Fig. 5, and having a slot 127 in which works a block 128 on the gear 124 operated from the motor M by other gears. The function of the stationary circularly grooved drum 121 is to support the loose portion of the thread in its periphery after the thread has been pulled out from the fabric by the puller 120. The drum has grooves 129, Fig. 10 to prevent entanglement of adjacent threads. A further safeguard against entanglement is provided in the brushes 130 which keep the threads in the grooves. Needle-threader. The needle 52 is threaded by a hook 66 carried by an arm 65 pivoted at 168 and swung down to threading position by a handle 167. The pivot 168 is on the needle bar 50 so that the threader is always correctly positionedforthreading. Whenthehook 66 pulls the thread through the needle eye, it is gripped by jaws 67, 68, opened when the threader is down but closed when the threader is up. The jaws are opened to release the thread by a cam projection 74 on the feed plate 73 engaging a roller 75 on an extension of the lower jaw 68.
