Title: Improvements in electronic control circuits for knitting machines
IPC: D04B15/66
Filed: 1959-11-20
Abstract: 877,248. Automatic speed control systems. SINGER-FIDELITY Inc. Nov. 20, 1959 [Dec. 2, 1958], No. 39391/59. Class 38 (4). [Also in Groups VIII and XXXVII] A circular knitting-machine, (Group VIII), driven by a D.C. motor 45, 46, 65, Fig. 2, or an A.C. motor 91a, 91b, 91c, Fig. 3, has a pattern drum for governing predetermined operations of the machine, a pattern chain for governing the operations of the drum, and an electrical speed control circuit for and including the motor, and including a saturable core reactor 55, or 97b and 97c, a potentiometer 22 or 22<SP>1</SP> adjustable to effect variations in the speed of the motor in accordance with the variations in the operation of the machine as prescribed by the pattern drum, means for relatively adjusting the potentiometer including a cam follower and a coacting cam carried by the drum, a second and independent potentiometer 23 or 23<SP>1</SP>, a solenoid switch 35 or 35<SP>1</SP> for selectively and individually connecting the potentiometers in the circuit and switches 33, 41 or 33<SP>1</SP>, 411 responsive to movement of said chain and drum for actuating the solenoid switch. The cam and follower effect setting of potentiometer 22 or 22<SP>1</SP> in positions corresponding to normal high speed and a low speed; and potentiometer 23 or 23<SP>1</SP> controls the machine at an intermediate speed for which the potentiometer is manually set. Gate windings 56a, 56b of the reactor 55 are connected across power lines 49 through a rectifier arrangement 59a-59d; the output winding 58 energizes the armature 45 and a series field winding 65. Control winding 57 of the reactor is so arranged that, as the current through it increases, the impedance of windings 56a, 56b decreases. The shunt field winding 46 is fed from a secondary 61 of a transformer 39, through rectifier 69; the potentiometers 22, 23 are across this field winding. In the arrangement of Fig. 3, motor field windings 916, 91c are connected to power lines 92b, 92c through gate windings 95b, 96b and 95c, 96c of reactors 97b, 97c and rectifiers 98b, 99b and 98c, 99c. Current flow through the control windings 118b, 118c produces flux opposing that due to current in the gate windings, whereby current to the motor windings, and hence motor speed, may be controlled. The current fed through control windings 118b, 118c depends on the particular potentiometer 22<SP>1</SP> or 23<SP>1</SP> in circuit and its effective resistance. The control windings are in series with a rectifier 122 and the field windings 119 of a tachometer 120, the armature 121 of which is turned by the motor shaft. Current generated by the tachometer opposes the fields of the main windings, thereby reducing total current fed to the motor as current in coils 118b and 118c is increased with motor speed. Specification 817,083 is referred to.

Title: A process for the manufacture of plastics from polythioethers and polyisocyanates
IPC: C08G65/34
Filed: 1960-11-18
Abstract: A process for the production of plastics comprises reacting one or more polythioethers containing sulphonium groups and having O-and S-ether bridges and terminal OH and/or SH groups with an alkyl acceptor forming nucleophilic ions containing nucleophilic groups at a temperature from 70 DEG C. to 180 DEG C. until the sulphonium complexes of the polythioethers are split, removing the alkyl acceptor together with the catalyst of the polythioether preparation if it is still present and reacting the polythioethers thus treated with one or more polyisocyanates and if desired a cross-linking agent.  Alkyl acceptors specified are OH ions, aliphatic hydro aromatic, araliphatic and aromatic primary, secondary or tertiary amines, hydrazine derivatives, ammonia, metal alcoholates and phenolates, mercaptides, thiocyanic acid salts of organic or inorganic bases and organic compounds with active methylene groups such as diethyl malonate.  Treatment with ammonia at elevated pressure in the presence of water, an alcohol, a mercaptan or a thioalcohol can also be used.  Organic bases are preferably used in the presence of water, an alcohol or a thioalcohol. With OH ions the treatment is preferably effected in the presence of a metal alcoholate or of a mono-or dihydric alcohol. The treated polyethers together if desired, with polyesters or polyethers can be reacted with the polyisocyanates to give non-porous or foam materials. Products obtained using excess polyisocyanate can be cross-linked with glycols, diamines or water or converted to storage-stable amino-or hydroxy containing material which is converted to elastomeric material by reaction with additional diisocyanate or other cross-linking material such as formaldehyde. Foam materials can be obtained by a single or two-stage process.  In Example(1) a polyether prepared from triethylene glycol and thio-diglycol in the presence of phosphoric acid and maleic an hydride is heated with ammonia and water in an autoclave. After removing the water the polythioether is filtered hot, leaving the catalyst and maleic acid in the form of ammonium salts or ammoniacal solutions or asparaginic acid. The polythioether is reacted with 1,5-naphthylene diisocyanate 1,4-butylene glycol is added, and the mixture is cast and cured. In other examples treatment of the polythio ethers is effected with (3A) triethylamine and water (3B) hydrazine hydrate and water (3C) ethanol and liquid ammonia, (3D) aqueous sodium hydroxide, (3E) diethyl malonate, calcium carbonate and toluene.  The products are mixed with N,N-bis (b -hydroxyethyl)-m-toluidine and 4,41-diphenyl methane diisocyanate, and heated at 100 DEG C. to give a material which is rolled into sheets. Carbon black, stearic acid and finally paraformaldehyde are mixed in on cooled rollers and vulcanization is then effected by heating at 151 DEG C.

Filed: 1967-09-05
Abstract: 1,135,700. Television. INTERNATIONAL BUSINESS MACHINES CORP. 5 Sept., 1967 [28 Sept., 1966], No. 40621/67. Heading H4F. The invention relates to displaying on a cathode-ray tube a quadruple interlaced scan video signal (i.e. a video signal in which the frame period is divided into four field periods during each of which a pulse train corresponding to the scan of every fourth line is generated) in such a manner that the effective frame rate is doubled e.g. from 15 to 30 frames per second. As shown, Fig. 1, the field V and line H sync. signals on lines 14 energize sweep circuits 16 and the video signal on line 12 is fed to amplifiers 28 and 26 directly and via a delay unit 22 having a delay of two field (V) periods i.e. half a frame period. Auxiliary deflection plates 34, arranged to vertically displace up or down the electron beam by a distance corresponding to successive scans of the image represented in the composite signal, is connected through a switch 36 to receive the complementary outputs of a square wave generator 38 having a pulse repetition rate of about twice the bandwidth of the video signal. Thus the horizontal line traced by the electron beam is segmented vertically and since amplifiers 26 and 28 are also gated into operation at the same rate by the output of generator 38 small portions of the two (direct and delayed) video signals are alternatively displayed on alternate sweep lines of the display tube i.e. the information contained in fields 1 and 3 is displayed during one field period (1/60 sec.). When switch 36 is open, alternate scan lines are displayed simultaneously on the same horizontal sweep line of the electron beam. The delay unit 22 may comprise magnetic drums or disks, magnetostrictive elements, or magnetic cores operated in readwrite cycles.

[Also in Group XL (c)] A transistor circuit for driving a saturable magnetic core 11 and in which a winding 17 on the core 11 is arranged in the collector circuit of a transistor 12 to the base electrode of which negative-going driving pulses are applied, comprises a further saturable core 18 having a winding 16 connected in series with the winding 17, a biasing winding 22 and a feed-back winding 23, the arrangement being such that on the application of a driving pulse, the transistor 12 conducts, thereby initially switching core 11 and then, with the reduction of impedance of winding 17, core 18 to produce a feed-back pulse in winding 23 to switch the transistor 12 off. As a consequence heavy current flow through the transistor 12 following upon the switching of core 11 is avoided. The core 18 is so biased by a steady current flowing through winding 22 that it does not switch until core 11 has been switched and the impedance presented by winding 17 has decreased. In the arrangement illustrated, feed-back is effected through a transistor amplifier 25 though in a modification, Fig. 3 (not shown), the feed-back signal from winding 23 is applied directly to the base of transistor 12, a diode being provided to short-circuit the feed-back pulse of opposite polarity occurring when the core 18 is reset. On the transistor 12 being switched off, core 18 is reset by the current in winding 22. Core 11 may be reset by a signal applied to winding 28.
