Patent GB-460677-A (GB)
Abstract: 460,677. Charging batteries. KOEHLER MANUFACTURING CO. Dec. 30, 1935, No. 35945. Convention date, Dec. 28, 1934. [Class 38 (iv)] [Also in Group XI] In a miner's lamp comprising a headpiece containing an electric lamp, and a storage battery charging terminals for the battery are exposed on the headpiece and a device inside the headpiece normally holds open a connection between one of the charging terminals and the battery, both manual and magnetic actuation of the device being necessary to close the connection. The headpiece 2 which may be of hard rubber or cellulose acetate has at the back a metal clip 3 for fastening to a miner's cap &c., and in the headpiece is a main lamp 4 and a smaller emergency lamp 5 mounted in holders on a removable insulating bracket 10. The lamp 4 has two filaments connected to separate terminals in the base of the lamp, the circuits being completed through the socket. A switch arm 37 operated by an outside knob 42 connects one terminal of the battery with any one of contacts 18<1>, 19<1> or 26<1> connected to the two filaments of lamp 4 and the lamp 5. The clip 3 is connected with the lamp sockets through a conducting bar 30 and is also connected to the other terminal of the battery. The back of the headpiece carries two terminals 44, 45 connected together and to a rock-shaft 47, Fig. 9, carrying a contact arm 48. Movement of the contact 48 is limited and a spring 5 maintains it out of the path of the switch arm 37. The rock-shaft also carries an armature 51 and when it is required to charge the battery, the headpiece is placed in the field of an electromagnet 52 as in Fig. 9 whereby the armature is rotated to move the contact 48 into the path of the switch arm 37. The knob 42 is then rotated to swing the switch arm into engagement with the contact 48, which contact is provided with a lip 54 entering a notch 55 in the switch arm. This operation completes the circuit between one side of the battery and the terminals 44, 45. To charge the battery, the headpiece is placed on a charging rack comprising an insulating bar 56, Fig. 7, slotted at 57. The clip 3 enters the slot 57 thereby making contact with a metal plate 58, and the terminals 44, 45 contact with ribs 62 on a second plate 61 insulated from the first. A number of these charging points may be connected in series and a spring 66 which normally shortcircuits a point is moved aside when a headpiece is inserted in the rack. To improve contact, a spring may be riveted to the plate 58 inside the groove 57, and the outer contact 61 may be in two parts as shown in Fig. 10.

Filed: 1969-09-18
Abstract: 1283766 Fusible cut-outs WESTINGHOUSE ELECTRIC CORP 18 Sept 1969 [1 Oct 1968] 46091/69 Heading H2G [Also in Division H1] A fuse assembly suitable for use in a liquid immersed transformer comprises an elongate tubular housing 174, formed of an insulating material, having electrodes 180, 182 disposed at the tube ends 176, 178 respectively. A solid liner, 184, of water vapour evolving arc quenching material such as boric acid extends along the length of the tube defining a square or rectangular cross-section arc passageway through which the fuse element 189 extends. The fuse assembly is sealed at one or both ends by frangible seals 191, 192 held in place by the electrodes 180, 182 which have openings axially aligned with the arc passageway such that, when an overcurrent of about a factor of ten occurs, the element 189 melts and an arc occurs along the length of the passageway resulting in the production of gases by the inorganic liner, including steam, which result in the fracture of the frangible seals and an escape of the gases from one or both ends of the tube, which in the process extinguishes the arc. A sub-liner, 190, may be provided which is of arc quenching material such as polyvinyl chloride which does not liberate water vapour when subject to the heat of an arc, the purpose of this liner being to extinguish arcs caused by overcurrents of between three to six times the normal load without breaking the frangible seals. In a further embodiment the fuse 92 (Fig. 3) is mounted inside a "plug in" type fuse holder 102 which includes an insulating receptacle 104 and a removable portion 106 to which the fuse assembly 92 is attached. The fuse 92 used in this embodiment is similar in internal construction to the one described except that it contains no frangible members being firmly sealed at its upper end and open at its lower end where it fits into a removable condenser 140 such that the gases discharged from the fuse assembly 92 will be confined to the condenser which may include copper screens 142 for causing the ejected steam to condense. Such an arrangement is useful when the fuse assembly is immersed in a liquid filled transformer as the gases are prevented from contaminating the liquid dielectric.

Abstract: 1,062,775. Boring earth etc; pile driving. P. GROSPAS. Dec. 3, 1963 [Dec. 5, 1962], No. 47673/63. Headings E1F and E1H. A percussive device such as a pile driver, hammer, or drill for earth boring has a rammer or bit 2 attached to a cable 1 and reciprocated by means of a crank 16 rotated by a differential gearing 13. The gearing is driven by a shaft M and has driven shafts 14, 15 respectively carrying the crank 16 and a crank 17. The cable runs over guide pulleys 3, 22, 23 and a pulley 20 on the crank 16, and is fixed to a drum 5 which pays out cable as the depth of the bore increases. A line 24 fixed at 29 passes over a pulley 21 on the crank 17 and a guide pulley 25 to connect to an elastic member 26 fixed at B. The resistance of the member is such that in normal operation the crank 17 does not pass top dead centre causing the crank 16 to accelerate after passing top dead centre so that rotation of the crank 17 is reversed until bottom dead centre is reached, the arrangement permitting free fall of the bit. In the event of a stuck bit the crank 17 rotates, the resistance of the elastic member being such that the cable is not unduly loaded. A cam 27 rotating with the crank 17 actuates a machine stop or reduces the resistance of the elastic member which may be a spring, an air filled piston and cylinder, or a combination of spring and piston and cylinder.

Abstract: 1,176,408. Conveyers; packaging cans. IWEMA A.B. 20 Oct., 1967 [30 Jan., 1967], No. 47894/67. Headings B8A and B8C. In a machine for feeding a predetermined number of uniform objects from a conveyer on to trays, cans 5 from a band conveyer 3 pass down an incline 9 on to a reciprocable plate 10 but are prevented from leaving the incline by a hinged stop 46 when the plate 10 is in its rearmost position. As the plate moves to its forward position, the cans on the incline are released, the front row of cans engages an adjustable abutment 35, and a tray 24 is moved up to a spring stop 31 by a pusher. 26 horizontally pivoted to the underside of the plate. The stop 46 is then returned to its upper position to prevent further cans leaving the incline 9, the plate 10 is returned to its rearmost position and the cans on it are deposited on the tray. Upon forward movement of the plate 10 again, the plate engages these cans which, together with the tray, are discharged to the left of Fig. 1. The plate 10 is reciprocated by a double-acting hydraulic piston-cylinder unit 21 connected to the plate by a chain 14 and the stop 46 is controlled by a slide 49 actuated by abutments 61 of the plate 10. Thus, just before the plate reaches its rearmost position, the abutments 61 cause the slide 49 to move to its rear position and the front portion 57 of the slide clears a roller 48 of the stop 46. This now falls and the cans on the incline 9 are stopped only by the presence of the cans in the leading tray. A beam 35 forms a stop for a batch of cans prior to their deposition in the tray. The incline 9 is provided with guide rails 7 and with a pivotable arm 6 for directing the cans into passages formed by the rails 7. Empty trays are fed by a roller conveyer 25. In a modification, Fig. 12 (not shown), the pivoted stop 46 may be dispensed with and the incline 9 may be in one piece.
