Abstract: 713,026. Electromagnetic relays; thermal switches. DIAMOND H SWITCHES, Ltd. Nov. 3, 1952 [Nov. 2, 1951], No. 25642/51. Class 38(5) A cyclically operating regulator for controlling the energy supplied to a load comprises a heat response element and a coil arranged to heat the element and also constituting a winding for energizing in electromagnetic relay controlling the load circuit, switch means actuated by the heat responsive element for controlling the circuit of the coil, and adjusting means to vary the ratio of the open and closed periods of the said circuits. As shown, the thermal element comprises an aluminium tube 9 insulatedly carrying a coil 11, and mounted between ceramic discs 10. An aluminium strip 13 welded to the tube has cranked ends 14, 15 extending through slots 16 in the tube ends, and a metal strip 17 of low expansion coefficient is riveted at 18 to the ends 14, 15. A contact 19 on the strip 17 is normally engaged by a contact 20 on a spring biased arm 21 having a bimetallic ambient temperature compensating extension 23 which co-operates with a cam 24 rotatable by a knob 26. On expansion of the tube 9 due to the coil 11, the strip 17 is straightened whereby the contact 19 leaves contact 20 when the extension 23 abuts the cam 24, and the coil circuit is broken. On cooling of the tube 9 the contacts 19, 20 re-engage and the cycle repeats. The ratio of the " on " and " off " periods is determined by the initial gap between the extension 23 and cam 24 and is adjustable by the knob 26. The electromagnetic relay comprises a core 4 within the tube 9 and riveted at 5 to a yoke 6, the magnetic circuit being completed by an armature 27 mounted on a spring 28 so biased that when the coil 11 is not energized it engages a back stop 35, and contacts 31, 33 controlling the load circuit are open, Hence when contacts 19, 20 disengage to de-energize the coil 11 the load contacts 31, 33 are also opened, and when the contacts 19, 20 re-engage, the contacts 31, 33 immediately reclose. The armature is insulated from the spring 28 by a plate 30 and has a locating projection 32 which engages the yoke 6. The core 4 has a shading coil 8 to limit vibration on alternating current.

Abstract: 520,078. Reciprocating conveyers. RICE J. H. Sept. 2, 1938, No. 25747. [Class 78 (i)] In the delivery of material from hoppers by reciprocating-ram apparatus, particularly adapted for under - feed mechanical stokers, the delivery is made in two stages by successive rams. As illustrated, a primary ram 3 feeds through a conduit of gradually increasing cross-section over a distributory baffle 5 to a pair of side chambers 7 through which rams 9 feed to the retort 10. In the preferred arrangement each ram 9 feeds a separate compartment of the retort. The collective size of the rams 9 is greater than the ram 3 and they are connected to the latter by the rack-and-pinion mechanism 13 so that they move inwards as 3 moves outwards and vice versa. The driving-gear comprises a motor 23 driving an oil-pump 22 which supplies oil under pressure to a distributing valve 21. This valve feeds the oil through a needle valve to the passages 18, 19 alternately, to operate the piston 16 to reciprocate the rams. An arm on one of the rack-bars operates a valve rod 25 to reverse the valve. Fig. 4 shows a preferred form of valve-control apparatus which forms the subject-matter of Specification 520,123, [Group XXIX]. In this case the rod 25 operates a pilot valve 52 which controls the admission of fluid to two pistons 57, 58 which fall by gravity. These pistons are connected to the piston valves which deliver to opposite sides of the main piston 16. The needle valve may be controlled thermostatically from the retort.

Title: Improvements in or relating to impregnating compositions for use in the manufacture of electric cables and condensers
IPC: H01B3/22
Filed: 1952-10-15
Abstract: A composition comprising an insulating oil and a synthetic hydrocarbon wax with polyisobutylene and/or polyethylene is used for impregnating fibrous material used for insulating cables or condensers.  The synthetic hydrocarbon wax may melt above 85 DEG C. and may be a product of the Fischer-Tropsch process or be produced by hydrogenation of less saturated naturally occurring hydrocarbons.  It may comprise up to 60 per cent. by weight of the composition.  The proportion of polyisobutylene or polyethylene is dependent upon the molecular weight of the polymer, e.g. up to 40 per cent. by weight of polymer of molecular weight approximately 1200-2500, and up to 10 per cent. by weight of polymer of molecular weight approximately 100,000. Petrolatum, rosin, and other resins of low dielectric loss, oxidation inhibitors and metal deactivators may also be present in the compositions.  The polyisobutylene and/or polyethylene may be dissolved in the wax in an inert atmosphere and the insulating oil added, or the polymer may be dissolved in a solvent, the oil and wax added and the solvent removed.  In an example a composition comprising polyisobutylene, a Fischer-Tropsch wax and an insulating oil is described.  Specification 650,088 is referred to.

Abstract: 1,271,844. Non woven fabrics. LUTRAVIL SPINNVLIES G.m.b.H. 21 May, 1969 [25 May, 1968], No. 25980/69. Heading D1R. Continuous filaments 1 are extruded from one or more rows of apertures stretched by gas streams forced out of slots parallel to, adjacent to and on each side of each row, led into primary duct 11, through which the filaments pass without turbulence, then led into a second duct 4 of diverging cross section in which the filaments are entangled by the supply and/or withdrawal of gas, and finally collected on carrier 8. Additional stretching may be caused by stretching rollers placed between ducts 11 and 4. Preferably air is supplied to duct 4 through slots 12 in the top of the duct. The air velocity is greatest along the sides of the duct, if necessary by supplying additional air through further slots (3-15, Fig. 2, not shown). The size of the vortices produced is thereby limited, so that the tendency to form fibre bundles is reduced. This may also be achieved by sucking air from the second duct through slits or pores. The delivery and/or removal of air may be pulsed, so that the filaments are caused to oscillate. This is useful if more than one pair of ducts is used to deposit filaments on the carrier 8. Oscillation by means of the Coanda effect is described. The walls of duct 4 curve outwardly at the end of the duct, a slot being positioned in each wall just before the beginning of the curvature. Air is supplied to each slot in turn, directed at the opposite wall, at a velocity such that the jet adheres to that opposite curved wall. The fleece may be impregnated with a binder.

Patent GB-1017020-A (GB)
Title: Process for the production of non-woven fibrous structures
IPC: B29C48/30
Filed: 1964-06-24
Abstract: A non-woven fibrous structure is made by forming a layer of a solution of a fibre-forming polymer on the surface of a temporary support containing perforations corresponding to the size of the fibres desired, forcing the said solution through the said perforations with a fluid which precipitates the polymer from the solution, and separating the non-woven fibrous polymer structure thus formed from the support.  Specified polymers include polyamides, polyesters, polyacrylonitrile and its copolymers, polyolefins, cellulose acetate, including the triacetate, regenerated cellulose, and mixtures thereof.  Specified solutions include a solution of polyethylene terphthalate in a mixture of equal parts by weight of phenol and 1, 2-dichloroethane, the precipitant being methyl alcohol, a solution of cellulose triacetate in a mixture of 4 parts by weight methylene chloride and 1 part by weight of ethyl alcohol, the precipitant being methyl alcohol, and a solution of a polyamide, e.g. polycoprolactam or polyhexamethylene adipamide, in formic acid, the precipitant being water.  Pigments or dyestuffs may be added to the polymer solution.  A metal cloth of mesh size 0.1 to 2mm. forms a suitable temporary support, and desirably the precipitant fluid moves at a speed of 0.25 to 2m./sec. with respect to the support carrying the layer of the polymer solution in a direction perpendicular to the surface of the support.  This may be effected either by passing a jet of precipitating fluid through the coated support or by immersing the coated support in the precipitating fluid and moving it therein in the direction in which it offers the maximum resistance to its advance.  The structures formed may be isolated by collection in a water bath so as to eliminate the included precipitating fluid, and, after drying, are either used directly or calendered, optionally after im impregnation with a conventional binder, e.g. a solution of a linear polyurethane in tetrahydrofuran.
