Title: Improvements in polyvinyl chloride and like compositions
IPC: C08K5/19
Filed: 1957-08-22
Abstract: One or more quaternary ammonium salts of the formula <FORM:0889022/IV (a)/1> are added to polyvinyl chloride or vinyl chloride/vinylidene chloride copolymers in amounts to render products made from the resulting composition sufficiently electro-conductive for the discharge of static electricity.  In the formula R is a C12-18 alkyl group and R1, R2 and R3 are alkyl, aralkyl or aryl groups. Quaternary salts specified are octadecyl dimethyl-, lauryl dimethyl-, coco dimethyl-, stearine dimethyl-, olein dimethyl-, cetyl dimethyl-, distearine methyl- and dicocomethyl-, -ethyl ammonium ethyl sulphate. The composition may also contain a non-ionic surface active agent, e.g. polyethylene glycol 200 laurate.  There are numerous exemplary compositions containing PVC and one or more of the above mentioned quaternary salts and various of the following ingredients: a di (mixed C7-9 alcohol) phthalate; white lead carbonate; lead stearate; trixylenyl phosphate; polyethylene glycol laurate; dinonyl phthalate; dioctyl adipate; an epoxy stabilizer/plasticizer; various proprietary stabilizers, extenders and plasticizers; carbon black; and an alkyl aryl phosphate stabilizer.  The compositions are particularly useful in the manufacture of conveyer belting or footwear.  Laminates.  The composition is particularly desirable for the surface layer of multiply belting but may also be used for interply layers or to impregnate fabric interplies.  In examples the compositions are used (a) for five-ply belting, the plasticizer and lubricant contents being varied for the portion used to impregnate fabric plies and that used for interplies and covers; (b) for the manufacture of footwear, optionally with an intermediate layer of the composition according to Specification 858,530, by pouring a liquid polyvinyl chloride composition into a shoe mould, semi-gelling by heat, pouring off surplus liquid, repeating, and finally heating further to gel all the layers together.

Patent GB-625128-A (GB)
Title: Improvements in means for controlling the operation and release of electro-magnetic relays
IPC: H01H47/16
Filed: 1946-09-06
Abstract: 625,128. Electromagnetic relays. GENERAL ELECTRIC CO.. Ltd., and OLLERENSHAW, C. Sept. 6, 1946, No. 26831. [Class 38(v)] Relates to arrangements such as in Fig. 1, wherein a relay 14 is enabled to release at a voltage across terminals 12, 13 only slightly less than the voltage needed to operate the relay by means of a barretter-type resistance 10 in parallel with the operating winding of the relay. The, resistance rises with increase in current and is high when the relay operates and low when it releases. For A.C. a rectifier 17 is included in circuit and a further resistance 15, and condenser 16 ensure that the relay releases rapidly should the current source be disconnected. Such an arrangement suffers from the defect that if the barretter burns out, the relay will remain operated when it should release. To remove the defect, according to the invention, a relay is used of the shunt field type, Fig. 3, the operating winding 14 of which is connected as above in parallel with the resistance 10, and the other winding 14<SP>1</SP> of which is connected in series with the resistance. In normal operation the windings co-operate to divert the flux through a magnetic shunt to operate the armature. Neither winding can by itself operate the armature so that if the barretter burns out, the relay releases. In a modification, the resistance 10 is adjustably connected across.part of the primary of a transformer the secondary of which feeds the coil 14.

Title: Rotary harrows
IPC: A01B33/08
Filed: 1975-06-24
Abstract: 1503033 Rotary harrow; overload release C VAN DER LELY NV 24 June 1975 [5 July 1974] 26835/75 Heading A1B A soil cultivating implement or rotary harrow comprising a plurality of soil working members 3 arranged in side-by-side relationship so as to be rotatable about corresponding upwardly directed axes is characterised in that at least one of the members 3 is provided with its own individual overload release or slip coupling. In a first embodiment, the slip coupling is provided between the shaft 2, embodying the axis of rotation of the member 3, and a pinion 4 imparting rotation to the shaft e.g. from the power take-off of a tractor. The pinion 4 comprises a central portion 34, keyed to a splined portion 14 of the shaft 2, and a peripheral portion 35 rotatable relative to the central portion 34 and including straight or spur gear teeth at its periphery. The peripheral portion 35 is normally keyed for rotation with the central portion 34 by means of spring-urged balls 38 engaging grooves 39 in the inner surface of the portion 35. Obstruction of the tines 29A causes the balls 38 to disengage from the grooves 39, rotation of the portion 35 being continued to enable the balls to reengage after a 180‹ turn. In an alternative embodiment, the slip coupling is provided between the shaft, embodying the axis of rotation of the member 3, and the tine support 42. This form of coupling is suitably employed in association with the pinion supplying the drive from the tractor to the remaining pinions. As shown in Fig. 4, the said pinion 4A is of solid construction and drives a shaft 41 which includes three transverse bores 44 housing springs 45 to urge balls 38 into grooves 39 in the inner surface of a tine support 42 mounted thereon. The bores 44 extend parallel to the longitudinal axis of the support 42.  In a further embodiment, Fig. 6, the tine support 53 is mounted for rotation on a sleeve 50 keyed for rotation with splined shaft, 2 driven by a solid construction pinion 4A. The sleeve 50 passes through the support 53 and includes an oblong portion 51 which mates with an oblong recess 52 in the support 53. The support 53 is spring biassed e.g. by cup springs 54, downwardly on the sleeve 50 whereby the portion 51 and recess 52 engage. Obstruction on the tines 29A during rotation causes the support 53 to rise against the cup springs 54 so disengaging the portion 51 and recess 52 to allow relative rotation. The longitudinal axes of the tine supports of adjacent members 3 in the side-by-side relationship, are preferably perpendicular to each other, the position of engagement of the slip couplings being located to maintain this arrangement. The members 3 are also arranged such that overlapping strips of soil are worked by adjacent members 3, the depth to which the tines penetrate the soil being adjustable.
