Abstract: 1450276 Knitting ELITEX-ZAVODY TEXTILNIHO STROJIRENSTVI GENERALNI REDITELSTVI 9 May 1974 [29 June 1973] 20411/74 Heading D1K The two ply constricted toe of a stocking has a central region including held stitches in alternate wales. The ply is commenced used half the available needles and knitting with two feeds, sinker loops are held on transfer bits of the dial. When one third of the total length has been knitted alternate active needles only knit at one feed. All active needles knit at the second feed, yielding held loops in alternate wales. Knitting on half the complement of needles is resumed for the final third of the toe. Elastic varn e.g. textured polvamide may be knit at the one feed: inelastic, eg. cotton at the second. The ply is constricted by twisting and using a wrapping yarn. The remainder of the stocking is knitted on all needles.

Title: Improvements in or relating to the manufacture of soap
IPC: C11D13/02
Filed: 1922-07-26
Abstract: Soap, in a white and inodorous condition ,is produced from soap made from inferior oils, fats and fatty acids, or waste products of oil and fat manufacture, or from soap-stock obtained in de-acidifying fats and oils, by spreading aqueous solutions of these materials over surfaces such as plates or rollers heated, for example to 90-150 DEG C.  By treating a thin film of soap at 100 DEG  C. a dry product is obtained which on cooling takes the form of flakes.  By using a lower temperature and a thicker layer of the solution, the amount of residual moisture can be regulated, and soap in pasty condition, suitable for making cakes or bars is obtained.  Specification 2266/10 is referred to.

Title: Improvements in or relating to television transmitting apparatus
IPC: H04N5/257
Filed: 1939-07-14
Abstract: 531,220. Electron-multipliers, modulating circuits for; television. GENERAL ELECTRIC CO., Ltd., and ESPLEY, D. C. July 14, 1939, No. 20541. [Classes 40 (iii) and 40 (v)] Apparatus for transmitting television signals of the kind in which the vision signal varies the primary current of an electron-multiplier and the carrier wave varies the multiplication factor, comprises means for providing a subsidiary current within the multiplier and for reducing this subsidiary current to zero or a low value by applying the synchronizing signal as a voltage pulse to a secondary emission electrode. Vision signals are thus represented by modulation above some datum level of the carrier corresponding to black in the picture, and synchronizing signals by modulation below that datum. The subsidiary current may be produced by illuminating the cathode, or one of the secondary-emission electrodes, with a light independent of the vision signals. A carrier wave is applied to an electrode later in the chain than that which gives rise to the subsidiary current, and its frequency may be an integral fraction of the radiated carrier. The synchronizing signal reduces the output to a low value by applying a voltage pulse to a secondary emission electrode which may make it negative relatively to the preceding electrode, or positive to a following electrode. The system may be utilized in association with that described in Specification 531,219. Specifications 492,662, 493,048 and 519,757 also are referred to.

Abstract: 627,922. Automatic speed control systems. ENGLISH ELECTRIC CO., Ltd., and ASBURY, A. Aug. 1, 1947, No. 21009. [Class 38 (iv)] [Also in Group XXXVII] A control system for operating a plurality of separately-excited direct-current motors at predetermined speed relationship comprises a source of supply for the armature of each motor, a master control rheostat for simultaneously varying the voltage applied to the armature of each motor, a reference rheostat ganged to the master control rheostat and providing a reference voltage depending on the setting of the master control rheostat, a tachometergenerator driven by each motor, an electronic amplifier associated with each tachometergenerator for amplifying any difference between the tachometer-generator voltage and the reference voltage, and means for automatically varying the speed of each motor in accordance with the amplifier output in a sense tending to reduce the difference of the two voltages. As shown, motors 10 and 11, which may drive parts of a paper-making machine, are supplied in parallel from a generator 12, a field winding 12a of which is excited, through a rheostat 14, from a constant voltage exciter 16. The motors have main field windings 10a and 11a respectively, supplied from the exciter 16 through rheostats 18 and 19. A field winding 10b of the motor 10 is supplied according to the difference of voltages derived from a motordriven tachometer-generator 22, and from series-connected rheostats 23 and 24, the difference-voltage being amplified by a unit 20. The rheostats 23 and 24 are supplied. from a rheostat 29, which is supplied from the exciter 16 and is ganged to the rheostat 14. The control of the field winding 11b of the motor 11 is similar to that of the field winding 10b, the excitation of these field windings being effected in a corrective sense in accordance with deviation of motor speed from a set value. Adjustment of the rheostats 14 and 29 simultaneously varies the voltage applied to the motor armatures and alters the reference voltages derived from rheostats 23, 24 and 27, 28. Rheostats 23 and 27 provide coarse, and rheostats 24 and. 28 afford fine adjustment. In a modification (Fig. 2, not shown), each motor is supplied from a separate generator, a master control rheostat being provided to vary simultaneously the excitation of all the generators. Each generator may have a field winding which is excited, similarly to the winding 10b, to provide a speed-corrective effect. The field windings which are excited by the outputs of the amplifiers may be energized to oppose the main generator or motor field windings, or they may be capable of producing both bucking and boosting effects.

Abstract: <PICT:0705208/III/1> In a method of applying a thermoplastic adhesive along a workpiece, which is moved through an adhesive-applying position, an adhesive, in solidified rod-like condition is caused to enter a chamber which guides the adhesive on its way to the workpiece, and is heated as it moves along said chamber so that it is applied molten, the rate of movement of the adhesive along said chamber and the rate of movement of the workpiece being so related that a desired amount of adhesive is applied.  The adhesive A, wound on a spool R, passes through a guide channel 184, and between feed rolls 82 and 84, which are grooved to grip the rod and push it through a guide bushing 78 into a member 56 having a cylindrical passageway communicating with a bored block 60.  The block 60 is electrically heated, and the adhesive is melted in member 56, passing from block 60 to a passageway in a creaser foot 16 (described in Specification 574,402), also heated, which, in conjunction with a folding finger 14, a hammer 18 and a guide finger 22 (described in Specification 544,010, [Group VIII]), folds a marginal portion of the workpiece.  Adhesive is applied through the hollow creaser foot 16. Mechanism is provided to rotate rolls 82 and 84 in relation to the movement of the workpiece, and to regulate the rotation to control the rate of application of adhesive.
