Title: Applying a layer of wires to linearly extended material
IPC: H01B7/22
Filed: 1977-11-17
Abstract: At least one ply consisting of a plurality of metal wires (9) is applied via guide grooves (7) to the surface of a strand (1), for example a cable core, by means of the hollow nipple (6) rotating in an alternating direction of rotation. In the run-on region (13) of the wires (9), a holding band (10) is wound by means of a band winder (11) on to the strand (1), into the windings of which the wires (9) are successively inserted. This holding band (10) remains on the strand above the wire ply. The wires (9) are consequently held securely after winding. So that the stranding cannot become twisted, there is arranged after the run-on region (13) a holding device (12) which is fixed or is displaceable axially relative to the strand (1) and which can consist of rollers radially adjustable relative to the strand. In order to improve the transverse conductivity of the stranding in an electrical cable, a conductive band (4), for example a copper band, is applied under the wires (9) by means of a band spinner (2). <IMAGE>

Title: Method of and device for charging a fluid-tight storage cell
IPC: H02J7/04
Filed: 1971-10-19
Abstract: 1362289 Battery charger for fluid-tight cells SOC DES ACCUMULATEURS FIXES ET DE TRACTION 19 Oct 1971 [29 Oct 1970 21 Dec 1970] 48613/71 Heading H2H A rapid charger for a battery of fluid-tight cells comprises means for deriving a reference voltage variable with the temperature of the battery and for continuously comparing this voltage with that appearing across the terminals 15, 16 of the battery and terminating the rapid charging in favour of a slower charge when the latter voltage exceeds the reference voltage. As shown, power is derived from A.C. mains via transformer 22 and rectifier bridge 23 and supplied for rapid charging via conductive thyristor 27 to the terminals 15, 16. A voltage indicative of the temperature of the battery is derived across silicon diodes 41-44 in thermal contact with the cells and is compared in a differential amplifier 32, 33 with a fraction of the voltage across 15, 16. When the reference voltage is greater than the terminal voltage, transistors 33, 30 in a second differential amplifier, and 29 in the triggering circuit of thyristor 27, are all conductive. When the terminal voltage starts to overtake the reference, transistor 32 becomes conductive and 33 blocked having the effect of rendering transistor 31 conductive to thereby raise the voltage drop across resistance 35 to sharply define the transition. Subsequently transistors 33, 30, 29 are all blocked and the thyristor is not triggered further. Slow charging is then effected via resistance 28. In a modification, Fig. 5 (not shown), the input transformer is not present and the battery is charged via a power circuit comprising a bridge rectifier and thyristor in series. The thyristor is triggered via a control circuit comprising a uni-junction transistor and capacitor, the firing-angle depending upon the rate of charging of the capacitor. The charging circuit of the capacitor has a voltage applied controlled by a differential amplifier and a further transistor to compensate for changes in the input (supply) voltage. Changing from rapid charging to slow charging is effected in a similar fashion, the switching transistor being in parallel with the base circuit of one of the transistors of the differential amplifier to change the firing point of the thyristor.

Abstract: 1,123,260. Feeding sheets. RANK XEROX Ltd. 19 Nov., 1965 [28 Dec., 1964], No. 49213/65. Heading B6B. Sheets are fed singly to feed rollers 11 from the bottom of a pile 41 by endless bands 12 cooperating with reversely-rotating rollers 14 which hold back the sheets above the lowest sheet, pivoted fingers 142 being raised to support the pile 41 above the bands 12 when the lowest sheet has started its forward movement and being lowered when that sheet has moved clear of the pile so as to allow the next lowest sheet to be moved forward by the bands 12. The bands 12, which move through slots in a support plate 10 for the pile, have foam rubber surfaces which exert a frictional force on the sheets greater than that between adjacent sheets, and the rollers 14 have around their periphery a rubber strip so as to exert a frictional force on the sheets which is greater than that between adjacent sheets but less than that exerted by the bands 12. A plate 40 with a gap 42 engages the front edge of the pile 41. In the inoperative state, the fingers 142 are held in raised position by a spring acting on the support shaft 144 thereof. When the apparatus is started, a solenoid (148, Fig. 7) is energized and rotates the shaft 144 so that the fingers 142 move downwardly and the bottom sheet is engaged by the bands 20. As that sheet moves forwardly, its front edge engages and opens a switch 146, 147 in the circuit of the solenoid (148), thus allowing the fingers 142 to rise. When the rear edge of the separated sheet passes the switch arm 147, the switch closes to lower the arms 142 and the pile so that the next sheet can be fed by the bands 12. Sheet guides; detecting faulty sheets.-A number of guide arms 125, 126, 127 (see also Fig. 2) with rollers 128 and freely pivoted on the shaft 16 of the rollers 14, rest on the separated sheet as it passes over the end of the bands 12. If a crumpled sheet is fed forward, the arms 125, 127 operate a switch 134, 136 to stop the apparatus. Feed tables.-At its upper end the plate 10 has a slidable frame 43 mounted thereon for supporting long sheets.
