Title: Improvements in rotary suspension bobbin holders for textile machines
Inventor: NOGUERA JOHN MICHAEL
IPC: D01H1/18
Filed: 1964-11-23
Abstract: 1,093,949. Bobbin supporting devices. CASABLANCAS Ltd. Nov. 16, 1965 [Nov. 23, 1964], No. 47644/64. Heading D1J. In Fig. 1 a rotary suspension type bobbin holder is shown with its pair of legs 11 in a raised and retracted setting within the spindle-like body 1, the legs resting at their lower end in dished seatings at the top of ramp surfaces 5a, 5b. Each leg has an inclined elongated slot 18 at its upper end through which extends a pin 19 slidable in a vertical slot 20, Fig. 3 (not shown), in the body 1. When a bobbin 22 is pushed upwardly onto the holder, it lifts the conical collar 6 until the collar strikes against projections 12 of the legs 11 to cause the legs 11 to lift off and swing away from the dished seatings, Fig. 2 (not shown). When the bobbin 22 is lowered, the cone 6, pin 19 and the legs 11 slide downwardly, the ramp surfaces 5a, 5b splaying the legs 11 outwardly so that they engage under a shoulder 24 of the bobbin to hold it, Fig. 3 (not shown). In this setting cam surfaces on the legs 11 and body 1 cause the upper ends of the legs 11 to retract into the body 1 by sliding across the pin 19. To release the bobbin it is again raised to push the cone 6 upwardly, recesses in the cone 6 then engaging projections 13 on the legs 11 to lift them up and over the ramp surfaces 5a, 5b and cause them to pivot about the pin 19 so that they swing towards each other Fig. 6 (not shown) to a position in which they can drop down, on lowering the cone 6, into the dished seating at the top of the ramp surfaces 5a, 5b. When resting in their dished seating the legs 11 are within the spindle and permit the bobbin to be withdrawn.

Abstract: 1,247,715. Sheathing cables. WESTERN ELECTRIC CO. Inc. 18 Oct., 1968 [20 Oct., 1967], No. 49470/68. Heading B5A. [Also in Divisions B3 and H1] A metallic sheath 22 (primarily intended as a moisture barrier) enclosing the core of a cable 20 is formed with its overlapping edges bonded together by a non-metallic adherent material to form a seam 40, the exposed outer surface of the sheath being free of the adherent material. The adherent material may be a thermoplastic polymerization product containing carbonyl groups (e.g. a copolymer of ethylene acrylic acid) and is solid at ambient temperatures.

Title: Device for starting and stopping a diesel engine
IPC: F02P19/02
Filed: 1970-10-22
Abstract: 1306466 Starting diesel engines AUTOMOBILES PEUGOT and REGIE NATIONALE DES USINES RENAULT 22 Oct 1970 [7 Jan 1970] 50166/70 Heading H2H A circuit for starting and stopping a diesel engine comprises a three position switch 2-6 having a first position in which a heating circuit and a starter circuit are open, a second position in which the heater circuit is closed whilst the starter circuit remains open and a third position in which the starter circuit is closed. To start the engine, the lever 2 is moved to the second position in which the contact 3 interconnects the contacts 4, 5 thereby energizing a relay 8 and causing contacts 12, 13 of a switch 9 to be interconnected. A battery 1 therefore energizes the coil 23 of a relay 24 via contact 19 of a switch 14 operated by a relay 16 the armature 16a of which closes a valve 17 in a fuel supply line 18. Contacts 38, 39 of the energized relay 24 are interconnected causing heater plugs 40 to be energized and a lamp 46 to be illuminated. Also, contacts 35, 36 are interconnected thereby energizing the relay 16 to open the valve 17 and close both a contact 22 of a switch 15 and a contact 21 of the switch 14. The coil 23 remains energized by the closure of contacts 30, 31. At the end of the heating period a ballast resistor 41 causes a bimetallic strip 42 to close a contact 43 thereby illuminating a lamp 45 whereupon the lever 2 is moved into its third position in which contacts 4, 5, 6 are interconnected. A relay 47 is therefore energized to supply power to a starter 48. When the engine reaches a given speed or when the oil pressure reaches a given value a switch 28 is automatically opened to de-energize the relay 24 thus cutting off the supply of power to the heater plugs 40. During operation of the starter a diode 51 maintains a zero potential across a heater 44 so that a bimetallic strip 25 cannot open a contact 26. However, if the starter is not operated within a predetermined interval after the contact 43 has closed, the heater 44 causes the bimetallic strip 25 to open the contact 26 thereby de-energizing the relay 24 and switching off the supply to the heater plugs 40. A coil 49 maintains the contacts 38, 39 closed to continue the supply of power to the heater plugs if the starter is operated when the contact 26 has opened. On moving the switch 2-6 to its first position a reverse current flows through the contacts 10, 11, 22, 33, 34 so that the valve 17 is closed. In a first modification contacts 33-36 of switch 32 are eliminated and in a second modification the supply circuit for the heater plugs is opened by the switch in a voltage regulator for the dynamo or alternator.
