Title: Filamentary sheet materials
IPC: D01F1/08
Filed: 1969-09-04
Abstract: 1279304 Sealing edges; tubular filaments; laminates INVENTA AG FUR FORSCHUNG UND PATENTVERWERTUNG 4 Sept 1969 [5 Sept 1968] 43808/69 Headings B5B B5K and B5N [Also in Division D1] Hollow filaments 2 of thermoplastic material such as polystyrene polymethacrylates, polyamides, polyethylene polypropylene, polyacetals, polycarbonates and polyvinyl chloride are formed into a web 3 in which they are substantially parallel to each other by passage through a drawing device 4 and a further drawing device 5 which acts intermittently. The web is cut into strips 7 by the cutter 6 which may be heated so as to fuse the capillary together at their ends. The strips 7 are stacked side-by-side into a sheet 42 by means of the pusher 8 and are carried along by the belt 11. The filaments 2 thus extend across the thickness of the sheet 42. The sheet may be bonded by infra-red or high-frequency heating. If the filaments are each double layered, the outer layer preferably has the lower melting point. Alternatively, a bonding agent such as acetylcellulose, epoxy resins, polyester resins and silicone rubber may be applied to the filaments before being cut. The hollow filaments may be inclined instead of at right angles to the surface of the resultant web. Two or more sheets of hollow filaments may be laminated with one another. An elongated spinneret for producing the filaments comprise, Fig. 3, a first feed duct extending along the length thereof to which polymeric material is supplied through an inlet 16<SP>1</SP> and a similar second feed duct 17 to which gas is supplied via an inlet 17<SP>1</SP>. Annular spinning orifices are formed by the co-operation of tubular pins 18, which are connected to the duct 17, and apertures 26 in the duet 16. Hollow conjugate filaments may be produced using a spinneret (Fig. 6) comprising a gas feed duct 31, a hollow pin 34 threaded at 37 so as to compress packing material 38, a first feed duct 33 supplying spinning material through the annular gap formed between bore 36, and tube 35, the gap between tube 35 and hollow pin 34 being supplied with a second spinning material through duct 32.

Abstract: 1,196,404. Endless conveyers. H. BRIDEN. 13 Dec., 1967 [30 Sept., 1966], No. 43913/66. Heading B8A. [Also in Division E1] A material-moving machine comprises a selfpropelled vehicle 1 provided with a front implement structure 21 having blades 6 which are reciprocated by hydraulic means. The structure includes two beams 2 pivoted about an axis 3 by a jack 4, and the movable blades 6 alternate with fixed blades 5 along the transverse leading edge of the structure, the two outer movable blades extending outwards at a small angle to provide clearance for the structure. Each blade 21 is reciprocated by an hydraulic hammer 8 connected to the blade by a member 7. Each member 7 has a thrust collar engaging a beam which transmits the thrust to two hydraulic control cylinders disposed one on each side of the member 7 and arranged to operate a pilot valve when the thrust exceeds a predetermined value, the pilot valve starting the hammer 8. Alternatively, the hammers may be controlled manually. The cut material is loaded on to two scraper conveyers 9 which feed it to scraper conveyers 15 mounted on a trailer 13 towed by the vehicle 1. The conveyers 15 can rotate separately about an axis 16 and each is connected to the associated conveyer 9 by a link 19, the position of the axes 3, 16 and the links 19 being such that movement of the trailer 13 relative to the vehicle 1 is accommodated. The structure may be rotatable through a small angle about a horizontal, longitudinal axis.

Abstract: 1,198,148. Copying records. EASTMAN KODAK CO. 29 Sept., 1967 [30 Dec., 1966], No. 44441/67. Heading G5R. In a re-recording apparatus in which a master record 10 is driven in synchronism with a copy record 12, the respective recording levels on the master and copy are compared and an electrical signal representative of the difference between them is produced and is used to control the gain of the re-recording amplifier 26. Variable-gain transmission circuits 44, 46 are controlled in accordance with the amplitude of the monitoring signal derived from the master record 10 to ensure that signals of usable magnitude are fed from the monitoring heads 32, 34 to the comparison circuit 60, 98. If the difference in levels between the master and copy records reaches a predetermined value indicative of possible malfunction, an alarm 106 is operated. At an even greater value, or in the absence of a normal monitoring signal from the master record for a predetermined length of time, a control circuit 120 stops the re-recording operation.

Abstract: 1,223,733. Starting discharge lamps. PHILIPS ELECTRONIC & ASSOCIATED INDUSTRIES Ltd. 27 Sept., 1968 [30 Sept., 1967], No. 46024/68. Heading H2H. A starting arrangement for a discharge tube 4 having preheated electrodes 5, 6 comprises an inductor 3 in series with the tube 4, a semiconductor controlled rectifier 9 connected across those terminals of the tube remote from the input terminals, a control circuit for the rectifier 9 and a capacitor 8 in series with a resistor 7 connected across the tube. The control circuit may comprise a disc 12 connected between the control electrode of the rectifier 9 and the junction of a resistor 10 with a capacitor 13 and a resistor 11. When the A.C. supply is switched on, the disc 12 becomes conductive when the capacitor 13 is sufficiently charged. This causes the rectifier 9 to conduct so short-circuiting the rectifier, the subsequent cessation of the current through the rectifier effecting the removal of the short circuit so that the capacitor 8 can charge rapidly and produce a high ignition voltage.
