Abstract: 1,117,187. Rolling wire. SCHLOEMANN A.G. 31 Dec., 1965 [31 Dec., 1964], No. 55354/65. Heading B3M. A wire finishing with train includes a group of roll sets I to VIII driven by a motor 2 through gearing 3, alternate sets being horizontal and vertical, and a final group of two sets IX and X, driven through gearing 5 by a motor 4. For a range of finished wire sizes an appropriate number of the sets I to VIII is removed, and the sets IX and X changed to produce the desired finished size, no additional roll sets being required. The reduction per pass for the sets is the same for each set in the first group, and is calculated from the sum of the positive and negative percentage tolerances of the original wire stock, plus the percentage reduction caused by an increase in the tension exerted on the wire from the second group. For example, a reduction of 18% is used for a tolerance of Œ8% with a 2% reduction in area caused by the tensoin.

Abstract: 1316615 Programmed control of textile machines E MAYER [trading as MAYER & CIE] 2 Dec 1970 [5 Dec 1969] 57152/70 HeadingG3N [Also in Division D1] An electric pattern attachment for a multisystem circular knitting machine having a revolving needle cylinder and electromagnetically actuated selector members responsive to a knitting pattern programme carrier, incorporates a mechanical gear for co-ordinating the movement of the needle cylinder with the reading of the programme carrier. The programme carrier can be in the form of a tape or a plugged matrix and control the selector members through pattern repeat stores of an intermediate store. As shown, the mechanical co-ordinating switchgear comprises a driving shaft 301 is coupled to the needle cylinder, not shown, so that 1 revolution is equal to the spacing for one knitting system and drives, through a differential gear 305, a shaft 307 bearing a disc 311. The disc 311 carries on its periphery binary coded information, relating to the pattern repeat width, which is read by a photo-electric scanner 312. The shaft 307, through a reduction gearing 308, drives a shaft 309 bearing a disc 321 carrying peripheral binary coded information, related to the knitting system sequence, which is read by a photo-electric scanner 322. At the end of the knitting system sequence the rotation of the shaft 307 is inhibited for half a revolution, to compensate for the needle gates, by the rotation of the planetary cage of the differential 305 by a Maltese cross mechanism 343, driven from the shaft 301 through gearing 345, engaged by a lever 347 operated by a control cam 346 on the shaft 309. When a stationary fixed pattern store is used, additional geared programme discs 331, 332 can be provided to control the use of two knitting colours. In a modification, for use when the pattern repeat width, in terms of stitch wales, exceeds the number of needles two of each of the programme discs 311, 321, are provided and inter-connected by gearing.

Title: A system for selecting a displaceable element such as a tape punch
Inventor: EHRAT KURT
IPC: G06K1/02
Filed: 1969-11-24
Abstract: 1,249,956. Machines for selectively punching. CIBA-GEIGY Ltd. 24 Nov., 1969 [25 Nov., 1968], No. 57443/69. Heading B4B. In a machine for selectively operating a member 2 which may be connected to a punch, an interposer 3, pivotally mounted on a reciprocating block 1, is coupled to an armature 5 of an electromagnet 4 by a torsion wire 6, the electromagnet being energized at least on the latter part of the downward stroke of the block 1 to attract the armature and cause the torsion wire to align the interposer 3 with the member 2. The block 1 is reciprocated by a shaft 9 through crank means 7, 8, the phase being sensed by a magnetic pick-up 13 or a photoelectric detector (not shown) which generates an alternating current transmitted to a control unit 14 which receives an input signal St.B. The block 1 has an extension 15 which pivots the armature 5 as the block is reciprocated. This causes the interposer 3 to swing inwards to press with its side face against the head 20 of the member 2. When a pulse of current from the control unit 14 flows through the electromagnet coils, the armature is held in its upper position against the action of a restoring spring 18 or (18<SP>1</SP>), Fig. 2 (not shown) the spring having enough play to prevent its full force acting on the armature. The raised armature causes the torsion wire 6 which may be spring wire and may be integral with the armature, to align the interposer 3 with the member 2 when it clears the head of the latter in descending so that on the return stroke the member 2 is moved upwards by the interposer against the action of a spring 10. Stops 16, 17 limit the movement of the interposer 3 which may be plastics and there may be a plurality of similar members 2 operated by similar devices, Figs. 4-6 (not shown).

Title: A control arrangement for controlling a single-phase/polyphase direct converter connected to a single-phase mains supply for the generation of an output voltage composed of complete half-cycles
IPC: H02M5/27
Filed: 1967-12-20
Abstract: 1,212,029. Converting; control of A.C. motors. VILLAMOSIPARI. KUTATO INTEZET. 20 Dec., 1967 [20 Dec., 1966], No. 57808/67. Headings H2F and H2J] A single-phase/polyphase converter for the generation of an output voltage composed of complete half-cycles is controlled by a triggering circuit A supplied with polyphase signals from a ring counter B, a logic circuit supplied from the single-phase supply and from the outputs of the ring counter being provided to delay triggering of the conveter until the waveform of the single phase supply passes through zero. This ensures that the output b, Fig 2, contains only complete half cycles of the single phase supply. Fig. 1 (not shown) relates to six pairs of thyristors connected across a centre tapped secondary of a single phase transformer, the thyristors feeding the split stator windings of a three-phase synchronous motor. The thyristors are triggered by circuits 1g-6g controlled by NOR gate 21-26<SP>1</SP> each having three inputs respectively supplied with antiphase square waves derived at 20 from the single-phase supply, with the output of a ring counter B driven by a pulse generator 10 at a frequency determined by input voltage Uf and by the output of an inhibiting circuit C consisting of a monostable circuit 30 triggered by the single phase supply, NOR gates 11-16 and bi-stable multivibrators 27-29. The inhibiting circuit C prevents periodic short circuits caused by the inductive coupling of the split stator windings when two thyristors are simultaneously triggered. This enables the output frequency to be raised to 80-90% of the single-phase frequency.

Abstract: 1,219,107. Controlling washing machines. ROBERTSHAW CONTROLS CO. 20 Dec., 1967 [28 Dec., 1966], No. 57830/67. Heading D1A. [Also in Divisions F2, G2 and G3] A speed selector mechanism for the agitator 23 and bowl 22 of a washing machine comprises a diaphragm servomotor 42 having a diaphragm 49 movable in steps under the control of manual selector valves 93, 94 (Fig. 2) to actuate a variable pitch pulley 31 via lever 36 against the action of tension spring 29 acting on the pivoted baseplate 27 of reversible motor 26. As shown, the diaphragm 49 has a post 53 provided with circumferentially spaced vertical cam tracks 67 of varying length. These tracks cooperate each with a respective one of a number of balls 62 cooperating with a flexible sleeve 66 to control communication between chamber 50 and a respective groove 57 in tubular guide 54. Grooves 57 and passages 72, 74, 75 are connected by respective lines 68-71, and 73 to ports 97-101 and 97'-101' in plates 96, 96' of valves 93, 94, and rotary flexible reading sheets 103, 103' serve to connect these ports to vacuum source ports 102, 102' by means of blisters 107, 107'. Valve 93 is set to control the speed of agitation and valve 94 controls the speed of spinning. Ports 102, 102' are connected to the vacuum source by blisters 194 in a rotary programming sheet 193. Diaphragm 49 will take up a position depending on which of the ports 97-101 (or 97'-101' if valve 94 is operative) is connected to port 102, since the diaphragm will move until a cam track 67 releases its ball 62 to allow sleeve 66 to close the groove 57 leading to the effective port. Although each reading sheet is intended to be moved to calibrated positions corresponding to those of diaphragm 49, the blister 107 ensures that the diaphragm will be actuated even if the sheet is moved to a position intermediate the calibrated positions. Valves 93, 94 may have other than a triangular blister in the reading sheets. In Figs. 10 and 11, not shown, port (102) is off-centre and the blister has a central ring (109) connected by radial portion (111) to arcuate outer portion (112). The motor can be two-speed, in which case each blister has an extension (137, Figs. 12-15) to actuate a switch which when the reading sheet is moved beyond a position corresponding to maximum pulley diameter at low speed, causes the motor speed to increase whereby further rotation of the reading sheet allows selection of a new set of machine speeds.

Abstract: 1380709 Touch responsive switches WESTERN ELECTRIC CO Inc 23 Dec 1971 [28 Dec 1970] 59904/71 Heading GIN [Also in Division H I ] In a touch responsive capacitive switch the operating capacitor is formed by a movable flexible electret sheet 13, Fig.1, carrying a conductive layer 13c, and a fixed electrode 11. In Fig. 1 an array of electrode surfaces 11 are supported in plate 12, and a metallized electret sheet 13, 13c over-lies them. A top plate 14 defines finger holes opposite the electrodes 11. When pressed by a finger the electret sheet and its conductive layer are displaced, and a voltage is developed across the electrode 11 and layer 13c; the voltage waveform depends on the input time constant of the associated amplifying circuitry, Fig.4 (not shown), and the peak may reach 20 volts. Push buttons may be used, as in Fig.2, to displace the electret sheet. In this figure an optional uncharged sealing sheet 18 is shown, and this may carry conductors which act as switches for auxilliary devices, e.g. lights, to indicate which button has been pressed. The heads of the buttons act as stops; the buttons are biased by the flexibility of the sheets 13 and 18, though extra springs may be used. In another embodiment, Fig.3 (not shown), two electret films are used in each capacitor, with a common third electrode so that each switch gives two output pulses. A delay unit separates the pulses. One of the electrets may be positively charged while the other is negatively charged, so that the pulses are of opposite polarity. Multiple electrets and delay units allow more complex pulse trains to be generated.  The conductive layer on the electret sheets may be restricted to regions opposite the fixed electrodes. It is stated that the devices are insensitive to acoustic signals, and to mechanical shock e.g. due to dropping. The device is also stated not to suffer adverse effects following frequent operation.
