IPC: B29C48/06
Filed: 1956-01-09
Abstract: 802,530. Materials composed of adhesively bonded filaments. STOHR, C. Jan. 9, 1956 [Feb. 17, 1955; April 12, 1955; April 20, 1955; July 7, 1955], No. 750/56. Class 140. [Also in Group XXV] In a process for the production of a selfsupporting lattice-like wound hollow member, filamentary material in the form of plastic thread or plastic covered wire or thread is wound on to a mandrel in such manner that later wound wire or thread crosses earlier wound wire or thread at many points. the crossing filaments being welded together by heat at the said points, thereby to form said member which is subsequently withdrawn from the mandrel. Specified plastics may have a base of polyamide, polyvinylchloride or polyethylene. Specified wires are of steel or bronze. Metal dust, powdered mica or air may be admixed with the plastic to produce a rough surface. As shown in Figs. 4 and 5, a container 6 holds liquid plastic 7 and a wire 8 is guided through the container by means of roller 9 and issues coated with plastic from a nozzle 10, and is then wound on to mandrel 11 which is provided with pins 12 to support the wire. The mandrel is reciprocated axially and simultaneously carries out a rotational movement. The plastic covering of the wire issuing from the nozzle is soft so that the wires become firmly bonded to one another at the points of intersection 14 when the plastic has solidified. The pins 12 are then retracted into the mandrel and the wound hollow member is removed therefrom. As shown in Figs. 6 and 7, an outer nozzle ring 28 and an inner nozzle ring 29 comprise nozzle openings 30 and 31, from which the wires or filaments are extruded. The rings 28 and 29 may be rotated in opposite directions or turned intermittently relatively to one another. Within the nozzle rings is mandrel 32 around which the shaping takes place to form tube-like structures or hollow bodies closed on all sides. Mandrel 32 is mounted on pin 33 having a bore 34 which can be used as a nozzle for a centred extruded length. Cutting knives 35 and 36 are arranged concentrically with the pin 33, and the knives, together with mandrel 32 and pin 33 are movable axially in the extrusion direction. Operation of the knives 35 and 36 presses the wires or filaments issuing from the nozzles inwardly and against mandrel 32. Continued inward movement of the knives presses the wires against the pin 33 and cuts them off.

Title: Improvements in and relating to delayed tripping mechanisms for electric switchgear
Inventor: BEDDOE STANLEY
IPC: H01H71/44
Filed: 1956-01-11
Abstract: 846,462. Automatic circuit-breakers. ENGLISH ELECTRIC CO. Ltd. Jan. 11, 1957 [Jan. 11, 1956], No.937/56. Class 38 (5). A circuit-breaker has an overload coil 13 wound about a core 11 so as to attract a pivoted armature 10, to trip the circuit-breaker, against the action of both a spring 12 and a time delay device which is rendered ineffective after a predetermined movement of the armature 10. The device comprises a link 15 pivoted to the armature 10 and to a lever 16 which is also pivoted to a bell-crank 19 movable about a fixed pivot A and connected to an oil dashpot 20, 21 having a non-return valve in the piston member 20 (Fig. 3, not shown). The lever 16 also carries a roller 17 which engages a cam 18 freely mounted on the pivot A and urged against an adjustable stop 26 by a spring 27. When the armature 10 is attracted to the core 11, the roller 17 first moves along the arcuate face of the cam 18 so that the lever 16 moves the crank 19 against the delaying action of the dashpot 20, 21. When the roller 17 passes the corner of the cam 18 the lever 16 can move without the crank 19 so that the dashpot has no further effect on the movement of the armature 10. The roller 17 moves the cam 18 against the action of the spring 27 during the latter part of the armature travel. Fig. 4 (not shown) illustrates means of current setting by adjustment of the spring 12, and means for setting the time lag by adjustment of the stop 26. An additional armature may be provided (Fig. 5, not shown) so as to be attracted by the core 11 at high overload currents, and move the stop 26 so that the time lag is reduced.

Title: Circuit arrangement for operating low-voltage halogen incandescent lamps
Inventor: HIRSCHMANN WALTER
IPC: H05B39/04
Filed: 1996-02-01
Abstract: To permit dimming of a halogen incandescant lamp, or set of lamps connected to an electronic transformer circuit which receives operating voltage from a power network, rectifies the current supply and chops the rectified power to provide high-frequency alternating voltage for transformation to low voltage of the incandesent lamp, a non-current compensated choke having an inductance of at least 50 mH is connected in series between the rectifier output terminals and the rectifier system terminals, an oscillation start acceleration circuit including a CR circuit is connected in parallel with the starting circuit for the alternately operating transistors and a pair of symmetry resistors (R6,R7) are connected in parallel to symmetry defining capacitors (C6,C7), connected across the rectifier output terminals and a mid-point (M) of the oscillation transistors. The arrangement permits soft starting of the transistors, even if a serially connected phase controlled dimmer circuit suddenly connects line voltage at peak value across the rectifier, while providing for continuous energy release, even if the dimmer control is turned beyond the 90 DEG  phase angle position and, for example, to 135 DEG phase angle.
