Patent GB-582500-A (GB)
Title: Improvements in or relating to lubricants
IPC: C10M159/12
Filed: 1943-09-09
Abstract: An extreme pressure lubricating oil composition consists of 85-95 per cent. by weight of a mineral lubricating oil and 5-15 per cent. of a solution of phosporus sesquisulphide in a sulphurized-chlorinated hydrocarbon, which solution contains 1-3 per cent. of phosphorus sesquisulphide.  The sulphurized - chlorinated hydrocarbon may be prepared by first chlorinating a hydrocarbon, such as paraffin wax, kerosene, aromatic petroleum fractions or coal tar distillates, and then reacting the chlorinated hydrocarbon with an organic or inorganic polysulphide, or both sulphurization and chlorination can be carried out in one step by reacting the hydrocarbon with sulphur mono- or di-chloride.  In an example, kerosene is chlorinated and the chlorinated kerosene thus produced is refluxed with an isopropyl alcohol solution of aqueous caustic soda and sodium hydrogen sulphide containing free sulphur admixed therewith. Phosphorus sesquisulphide is dissolved in the sulphurized-chlorinated kerosene obtained in this way and the solution dissolved in mineral lubricating oil.  For comparison purposes, a composition is made up of the sulphurized-chlorinated kerosene and mineral lubricating oil only. The Specification as open to inspection under Sect. 91 refers to an extreme pressure lubricating oil composition comprising a major proportion of a mineral lubricating oil, a minor proportion of a sulphur-halogen hydrocarbon extreme pressure lubricating agent and a small amount of phosphorus sesquisulphide.  This subject-matter does not appear in the Specification as accepted.

Shuttles of the hand-threading or suctionthreading kinds are provided with one or more weft-restraining elements applied direct to the shuttle peg at or near its free end, the free ends of the' elements being so shaped and protected as to present no portion on which the weft can become entangled. In the form shown in Fig. 1, two india-rubber wafers A fixed in the shuttle en. gage the end of the shuttle peg B. In a modification, a single wafer engages the end of the peg and is adjusted to suit shuttle pegs of different lengths. In another form, one or two light metal springs A<1>, Figs. 6 and 8, each secured by a pin a<2> in the shuttle side engage the shuttle peg nearits end, the free extremity of the spring being received in a hole a<3> in the shuttle. The shuttle shown in Fig. 8 is also provided with a handthreading plate D having a spur d arranged in a groove d<1> and a prong d<4> in a transverse hole in the shuttle. A groove, d<3> is formed in the platebetween the prong and the spur, and the plate is secured by pins d<6>, d<7>, the pin d<6> and a pin d<8> crossing the shuttle eye and preventing wear. The shuttle is threaded by passing the weft around the plate beneath the spur d, so that a loop presented at the eye can be pulled through the sameby drawing the thumb across the eye and along the longitudinal groove in the side of the shuttle. According to the Provisional Specification, the invention may be applied to a shuttle having a threading-device of the kind adapted to present a loop of weft through the shuttle eye and consisting of a piece of metal or wire folded upon itself and having its ends sprung into holes in the shuttle.

Abstract: 1,173,552. Solutions of vinylidene fluoride polymers. KUREHA KAGAKU KOGYO K.K. 29 March, 1968 [30 March, 1967; 4 Sept., 1967], No. 15087/68. Heading C3P. A solution of a vinylidene fluoride polymer comprises a solute which is a vinylidene fluoride polymer in powder form, which polymer is obtained by polymerization of vinylidene fluoride at a polymerization temperature of from - 50‹ to 80‹ C. and has an intrinsic viscosity of from 0.5 to 6.0, and a solvent for the polymer, which solution forms a transparent film on drying at ambient temperature, which film contains both α-form and #-form crystals of the polymer, the solute having been dissolved in the solvent at such a temperature that infra-red absorption peaks due to α-form and #-form crystals appear in the infra-red absorption curve of a film obtained by drying the polymer solution at ambient temperature. The term " vinylidene fluoride polymers " means homopolymers and copolymers having a content of vinylidene fluoride of at least 95% by weight and having essentially the same crystallization characteristics as vinylidene fluoride homopolymers and in which the comonomers are substances which do not exercise any substantial effect on the crystallization characteristics of the polymer. The viscosity is measured at a concentration of 0.4 g./100 c.c. in dimethyl formamide at 30‹ C. In the examples vinylidene fluoride is polymerized in the presence of water, methyl cellulose ether, isopropyl peroxidicarbonate, sodium salt of perfluorocapric acid, potassium persulphate and sodium bisulphate and the polymers dissolved in dimethyl acetamide, dimethyl formamide, dioxane, acetone and ethyl acetate.

Abstract: 1385615 Spray producers SOC DES ACIERS FINS DE L'EST 29 March 1973 [8 May 1972] 15143/73 Heading B2F [Also in Division F4] An atomiser comprises a cylindrical member 1 having a liquid passage 15 and a gas passage 12, the outlet aperture of the liquid passage being controlled by a needle valve 17 integral with an external closure casing 7 slidably mounted on the cylindrical member 1; and resilient means 20 acting axially in a direction to close the liquid outlet aperture by the needle valve and also to restrict the gas outlet aperture by the casing. The restriction of the gas outlet aperture causes pressurised gas flowing through the passage 12 to slide the casing 7 against the action of the resilient means to open the needle valve and also to allow the gas to flow more freely from the gas outlet aperture. When the casing 7 is in the position in which the needle valve 17 closes the liquid outlet aperture the gas is restricted to flow through three passages 24, and when the casing slides to open the needle valve gas then discharges via an annular gap formed between the casing and member 1. The needle is mounted in the centre of the casing 7 by three radial arms 19.

Filed: 1964-04-14
Abstract: 1,099,321. Spray producers. J. D. PETT. April 14, 1965, No. 15329/64. Heading B2F. An irrigation machine having booms 4 carrying spray devices 7 and 8 comprises a chassis adapted to be propelled across the ground to be irrigated by the pressure of water supplied to the chassis through a hose 10. The chassis carries a winch drum 45 which is caused to rotate by piston actuated pawl and ratchet mechanism so as to move the chassis by shortening a cable connection 46 between the winch drums and an anchorage fixed with respect to the ground. The hose is initially wound on a drum 9 the water supplied through the hose from a hydrant somewhere on the ground passing to the interior of the drum before flowing through a pipe 23 to a valve unit 12 where it is used to reciprocate a piston in a cylinder 32 prior to passing to the booms 4 through a pipe 29. The piston is double-acting a water operated valve change-over unit being incorporated in the unit 12 for this purpose. The moving piston actuates the winch drum 45 through a lever linkage and the pawl and ratchet mechanism, and an adjustable plate is provided adjacent the drum 45 which enables the pawl to be raised, if necessary, during part of its travel over the ratchet thereby enabling the speed of the machine over the ground to be controlled. By lifting the pawl from the ratchet through the use of the plate the drum is freely rotatable so that the cable 46 may be unwound from the drum and anchored again as required in a new position. The hose 10 may be rewound on the drum 9 through the use of a handwheel 54 or a connection 57 from a tractor power take-off shaft.
