Patent GB-1228225-A (GB)
IPC: H04M1/278
Filed: 1968-11-12
Abstract: 1,228,225. Repertory diallers. R. POLI. 12 Nov., 1968 [15 Nov., 1967], No. 53622/68. Heading H4K. In a repertory dialler controlled by punched cards, the cards are stored in a magazine and each is displaced into a sensing position still in the magazine to dial the subscriber associated with that card. As shown, the magazine comprises a set of spacer members 5 between which the cards 1 may be inserted. Each card has the number of a subscriber to be called, punched out as a pattern of holes 101 one per horizontal row on the card, and has a continuous row of adjacent holes along its lower edge. In the normal position of the cards in the magazine the rows of adjacent holes are aligned and aligned with corresponding rows of adjacent holes in the spacers 5. These rows of holes together constitute a row of horizontal bores 6. Each bore 6 is filled with a row of balls 7 which are sufficiently closely packed that when any card is depressed as shown at 1 in Fig. 14 so that a hole in that card is not aligned with the bore, the balls displace a contact member 11 opening contacts g. They also prevent depression of two cards at the same time. To call a subscriber the card associated with that subscriber is selected and pressed downwardly to its lowest position in which the hole 101 in the top row of that card is in the sensing position, i.e. is aligned with one of the bores. In this position the contacts g associated with all other bores are opened and held open while the contacts g associated with that bore are allowed to close, supplying potential to a corresponding wiper 23 engaging the conductive edge of a notched disc 19. At least in the home position of the disc, a path is completed, via a rectifier bridge 25, to the winding 28 of a relay. The changeover contact 29 of this relay is operated, enabling a motor driving the disc 19 and a toothed wheel 13 operating impulsing contacts 14 connected to the telephone line 15 until the circuit is broken by a notch on the disc passing the enabled wiper. When this occurs the relay 28 releases, disabling the motor driving the disc 19 and enabling a motor 30 driving a cam 31 which causes the card to be pushed upwardly until the relay 28 is again enabled by the sensing of the hole in the next row in the card. The disc 19 rotates in the same direction for each digit and does not return between digits. Thus, for example, if the second digit is a "2" the hole 101 in the second row of the card must be laterally displaced by 2 units from the hole in the first row in the card so that two more wipers are swept during the second rotational movement of the disc 19 and two more impulses are sent by the contacts 14. This form of difference coding requires 11 possible column positions for the holes 101 and 11 bores if up to 10 pulses are to be sent for each digit. A keyboard may be provided to dial subscribers for which there is no punched card.

As the tuning voltage U A  is increased the tuning circuits I, III and IV and capacitive feedback circuits 10, 12, 13 operate the oscillator in bands I, II and UHF bands IV and/or V. When the tuning voltage U A  is higher than the bias U V1 , U V2  no voltage will occur across the bias diode 5, 9 and the difference between the tuning voltage and the bias will occur across the variable capacity diode 4, 7. When the tuning voltage U A  is lower than the bias U V1 , U V2  no voltage will occur across the variable capacity diode 4, 7 and the difference between the bias and the tuning voltage will be present across the bias diode 5, 9. The frequency determining elements in the tuning circuits may be proportioned in such a manner that any tuning circuit is active in the steepest possible part of the capacityvoltage variation curve (1, 2, 3, Fig. 3, not shown) of the associated variable capacity diode 3, 4, 7. The transistor 11 operates as a self oscillating mixer where the received frequencies for ranges I, II and UHF are applied at A, B, and C to provide an IF output at ZF. The circuit may provide a common TV tuner for VHF and UHF.

Abstract: 1485952 Knitting RIDLEY SPRIGGS & JOHNSON Ltd 27 Nov 1974 [12 Dec 1973 31 May 1974] 57655/73 Heading D1K A knitted flat blank 7 of waisted shape for a pair of briefs is formed by knitting a preliminary tubular blank on a circular hose machine either wholly by continuous rotary knitting or partly by continuous rotary and partly by reciprocatory knitting, and then slitting the tubular blank lengthwise and opening it out to give the flat blank. In Fig. 3 the blank 6 is produced wholly by rotary knitting with a waisted crotch portion 6c achieved by feeding different yarns and changing the stitch structure to cause a coursewise constriction. Suitably, in the portion 6c, alternate courses are each formed from two yarns - one synthetic and one cotton - knitted together but only at widely spaced wales, giving long floats. Intervening courses are formed from balanced-twist nylon yarns. In adjoining portions 6d, 6e, in every second course only alternate needles knit. Both the portions 6d, e and the portions 6a, 6b which are plain knit, have alternating courses of S and Z twist crepe yarns. In a modification the last-mentioned yarns may replace the balanced twist yarns in the crotch portion. In the Fig. 2 embodiment portion 1 is first knitted by rotary knitting and then two thirds of the needles are progressively put out of action by pickers while a narrowed portion of pouch 3 is knitted in reciprocatory manner. The remaining needles continue to knit a crotch portion in the form of a selvedged loop 4 at the point of the pouch and the other needles are progressively restored to action to complete the pouch 3, the preliminary blank being completed by a rotary knitted portion 2. The blank is then slit from F, F' to E, E' and from B, B', D, D' to A, A', C, C' and opened out to give a flat blank similar to the blank 7. When knitting the tubular preliminary blanks a few needles may be removed or selected not to knit so as to give a line of demarcation for the subsequent slitting step.

A double lift open shed Jacquard has hooks 2 comprising a leg 13 having a bottom neb 11 and two nebs 17, 18 on a pivoted lever 15. In use a hole in a card does not move the hook so that either rising griffe 9 or 10 may engage a neb 17 or 18 and lift the hook to the open shed position. A blank in the card will then move the neb 11 clear of an open shed frame 12 so that the book may descend with the griffe. The action of the griffe on either neb 17, 18 will tilt the lever 15, against the action of a spring 19, so that the free neb 18, 17 is clear of the other rising griffe during descent of the falling griffe.
