Title: Improvements in and relating to electrical time-overcurrent protective relays
Inventor: WARRINGTO ALBERT RUSSELL VAN C
IPC: H02H3/08
Filed: 1956-12-21
Abstract: 873,129. Induction relays; protective cut-out systems. ENGLISH ELECTRIC CO. Ltd. Dec. 16, 1957 [Dec. 21, 1956], No. 38946/56. Class 38 (5). A directional-time-overcurrent protective system has separate time-overcurrent and directional induction relays, the latter having means responsive to overcurrent which retains it in the operated position even if the voltage signal decreases due to fault proximity. As shown, the coil 12a of the time-overcurrent relay and the current coil 21b of the directional relay are in series with a coil 26a on a core 26 for retaining the magnetic contact-arm 22 of the latter relay in the operated position. The voltage coil 21c is arranged to resonate with a capacitor 29 to provide memory action and a resistance 28 helps to retain the energy in this circuit. A shading ring 21a prevents operation at currents up to the full-load current. On overload in the set direction the disc 19 closes the contacts 25 which complete the circuit of the shading windings 12c of the time-overcurrent relay and are held closed by the coil 26a until the overcurrent relay has operated. The return spring 24 and stop 23 may be omitted and a permanent magnet provided to hold the arm 22 in the normal position.

As shown the projector comprises (Fig. 1) supply and take-up spools 6 and 18 on spindles 8, 20 of shafts 28, 30 which are driven by belt and pulley mechanisms (Fig.3). Spindle 8 is driven when a lug 52 of a pulley 44 is pushed into engagement with a shoulder 54 of the spindle by the end of a pivoted clutch plate 62; spindle 20 is driven when a clutch spring 58 in a groove 56 of a pulley 52 engages a shoulder 60 of the spindle. The trailing end of the film is fixedly attached to the supply roll by a clip 106, and when the film has run-off a snubber 108 is pressed in by the tension film against a spring 111. This causes an arm 112 of the snubber to rotate a latch 92 anti-clockwise against a spring 86 thus releasing a lever 80 which is rotated anti-clockwise by spring 86; arms 122,124 thus release the film 14 from a claw 16 of the intermittent feed mechanism Fig. 4 (not shown), and an arm 100 thus releases a rod 64 and clutch plate 62 for clock-wise movement to declutch the drive from take-up spindle 20 and clutch it to supply spindle 8 so that the film is rewound.

Abstract: 1419960 Shrink and crease proofing keratinous material CIBA-GEIGY AG 20 Aug 1973 [1 Sept 1972] 40647/72 Heading D1P Keratinous material is proofed against shrinkage, and existing or future pressing is rendered more durable by treating the material with a polyene having at least two olefinic double bonds each beta to an oxygen or nitrogen atom and curing the polyene on the material by reaction with a polymercaptan having at least two mercaptan groups, the combined weight of polyene and polymercaptan incorporated in the product being 0.5 to 15% by weight of the keratinous material treated. The sum of the number of meroapto groups and the number of said olefinic double bonds is more than 4, e.g. 5 to 8. The polymercaptan is an ester of formula I where R<SP>1</SP> represents an aliphatic or araliphatic hydrocarbon radical of at least 2 carbon atoms, which may contain not more than one ether oxygen atom, R<SP>2</SP> represents a hydrocarbon radical, p is an integer of from 2 to 6, q is zero or a positive integer such that (p + q) is at most 6 and r and s each represent zero or 1 but are not the same. The keratinous material may be sheeps wool, alpaca, cashmere, mohair, vicuna guanaco, camel hair llama hair or blends thereof. It may be blended with polyamide, polyester, polyacrylonitrile or regenerated cellulose. The material may be in the form of fibres, filaments, fleeces, tops, card sliver, noils, yarn, threads and woven, knitted, non-woven and pile fabrics. The polyene and polymercaptan may be applied in either order or together as an aqueous solution or dispersion or non-aqueous solution. Preferably there are 0.5 to 1.2 olefinic double bonds per mercaptan group. The reactants may be applied to the material by padding or immersing the materials in a bath, by spraying or by exhaustion from aqueous solution or emulsion. Curing i.e. reaction of the polymercaptan with the polyene may be facilitated by catalysts by acids, amines or peroxides and/or by heating to 35 to 180C. A fabric may be flat set before or after treatment with the polyene and the polymercaptan using steam a swelling agent (e.g. urea) and diethanolamine carbonate or a swelling agent and a reducing agent. In run 3 of example 1 the polymercaptan is glycerol tri(thioglycollate) and the polyene is XIII where f is an integer of average value 22.5 and j is an integer of average value 0.3. They were padded together with diethylene tetramine as catalyst onto a wool flannel cloth to an uptake of 300% and the cloth dried at 65C in a fanned oven for 15 minutes. The product contained 0.2% by wt. of polymercaptan and 3.0% polyene.
