Abstract: 1,238,864. Welding by pressure. P. ESSER. 18 July, 1968 [19 July, 1967], No. 34152/68. Heading B3R. [Also in Division F2] A chain welding machine is provided with an electromagnetic clutch 26 for connecting the drive from a motor-driven pulley 24 to the shaft 30 of the machine and also comprises devices for feeding, fixing, upsetting and welding the chain links, a brake for acting on the shaft 30 and devices for monitoring and controlling the machine and chain movement. The electromagnetic clutch comprises a hub 28 secured to pulley 24 and rotatably supporting the end of the shaft 30, an electromagnetic coil 34 in the hub, an armature disc 36 axially movable but non-rotatably mounted on shaft 30 and a brake pad 42 non-rotatably mounted. The armature disc, which has a friction lining 37, is urged by springs 40 towards the brake 42 which also has a friction lining 39 so that upon de-energization of coil 34 the disc 36 is rapidly braked and rotation of shaft 30 is stopped. Current to the coil 34 can be controlled by each of the individual control devices, and a main switch may also be provided.

Abstract: 1,239,402. Oil-blast switches. A. REYROLLE & CO. Ltd. 12 Sept., 1968 [13 June, 1967], No. 27272/67. Heading H1N. An oil circuit-breaker has a tank 10 of moulded insulating material at the bottom of which the fixed circuit-breaker contact or contacts 14 is or are mounted, and in which the moulded interior of the tank is shaped to provide one or more pairs of co-operating guide tracks 30 which cooperate with a movable carrier 40 for the moving contact or contacts 37 to guide the moving contact or contacts into engagement with the fixed contact or contacts and to ensure correct alignment of the contacts. The circuit-breaker may be a three-phase double-break circuitbreaker whose tank contains moulded interphase partitions 12 which also provide guide tracks. These partitions 12 are integral with the tank which has webs 20 between the two turbulators 13 provided for each phase. Each contact carrier 40 has an insulating tube 41 which extends around a fixed piston 47 which damps the opening movement of the contact assembly. Various arrangements of the guide tracks and contact carriers are described and shown. The tank 10 may be a gravity moulding of cast resin or it may be a pressure moulding of chopped glass fibre impregnated with a resin, e.g. a polyester resin. The wall of the tank may have a pre-stressed wire, tape or cord reinforcement as in Specification 1,228,363.

Abstract: 1,250,136. Valves. GRISWOLD CONTROLS. 9 June, 1970 [9 June, 1969], No. 27830/70. Heading F2V. A valve 10 for use in an irrigation system is normally actuated by a solenoid-operated pilot valve 38 which when opened allows fluid pressure in chamber 31 to drain via passages 40, 34, 41 to the outlet 15 so that inlet fluid pressure moves the main valve member 20 off its seat 19 against the loading of spring 32. Inlet fluid pressure is communicated to chamber 31 via the space between stem 48 and bore 50 in the valve member guide 23 and the space between the metering pin 53 and the bore 55. Pin 53 is formed with a cylindrical portion 59 and a lower restrictor portion with a helical groove which portions in co-operation with the bore 55 respectively allow flow into chamber 31 at a faster and slower rate than the exit flow rate via the solenoid valve so that the open position of the main valve member is determined as a float position in which the flows are equal. The open position is adjustable by a threaded stem 60. When the system is to be drained, inlet pressure is removed and pressure fluid in chamber 31 can thus drain to the inlet through the main valve member which is then moved by a conical compression spring 67 to a drain position in which the guide 23 of the valve member co-operates with the bore in the seat to restrict flow through the valve. The main valve may also be opened by removal of plug 43.

[Also in Divisions C4 and G2] Aminoguanidine dialdehyde starch is prepared by adding acid and aminoguanidine bicarbonate to a dispersion of dialdehyde starch containing from 10-75% dialdehyde groups and allowing the mixture to react until the desired number of aminoguanidine groups have been formed. 7- 50% conversion of the dialdehyde groups are obtained in the preparations. This starch derivative may be further reacted with an anionic fluorescent dye such as a bistriazinyl compound or a ureidocoumarin to produce a less powerful fluorescent dye. The aminoguanidine dialdehyde starch may be used as a mordant and as a hardener for gelatine.

Abstract: 1295443 Cleaning; heating and guiding yarns in textile spinning &c machines HOWORTH AIR CONDITIONING Ltd 16 April 1970 [17 April 1969] 19597/69 Headings DID and D1F In a machine for processing yarn e.g. hot relaxing after a previous heating, cooling and setting, smoke and fumes are withdrawn from tubular heaters in a contradirection to yarn passing downwardly therethrough. The smoke &c emerges from the upper end of each tube through a device for creating a cyclonic or circular flow around each entering yarn to prevent deviation thereof. Humidified air is supplied to the device to encourage condensation. As shown, yarn 1 passes into a heater tube A through an eyelet b in a common ducting B (serving a line of heaters) to which suction is applied through an exhaust duct (A') to cause downward flow of air through eyelet b and suction through tube A sufficient only to remove smoke &c without cooling the tube. Eyelet b tapers to form a condensation ring. Smoke &c emerges from tube A into ducting B through device b<SP>1</SP> for creating a cyclonic air flow around the yarn passing through eyelet b<SP>2</SP>, thereby to maintain the yarn in its vertical passage through tube A. Air emerging from device b<SP>1</SP> is drawn from a chamber (b<SP>3</SP>) into the ducting B. Eyelets b<SP>2</SP> may be of varying diameter along a line such that the suction effect is equalised. The upper end of the tube A may project into the device b<SP>1</SP> or, as shown, into the ducting B the respective base thereof acting as an oil retaining tray. Humidified air is supplied to device b<SP>1</SP> from a second ducting (not shown) extending parallel to the first and having eyelets therein in line with eyelets b. A tubular, condensing ring (not shown) may be incorporated and/or humidified air may mingle with heated air from the heaters.
