Title: Electrolytic Coppering of Niobium Alloy Bodies
IPC: C25D5/38
Filed: 1967-01-04
Abstract: 1,152,091. Electro-depositing copper; cleaning niobium alloy surfaces. PECHINEY COMPAGNIE DE PRODUITS CHIMIQUES ET ELECTROMETALLURGIQUES. Jan. 4, 1967 [Jan. 6, 1966], No. 572/67 Headings C7B and C7E. A super-conducting niobium-base alloy body, e.g. containing 60-90% Nb and 40-10% Zr or Ti, is surface treated by degreasing e.g. using C 2 HCl 3 , deoxidizing and acid pickling e.g. in concentrated mixtures of HF-H 2 SO 4  and HF-H 2 SO 4 - HNO 3  respectively, then subjected to chemical action on the surface with an aqueous bath containing 10-100 g/l NH 4 F and 15-100 cc/l 40% HF solution, prior to electrolytic coppering, e.g. in a bath containing 300-600 g/l copper fluoborate and 30-60 g/1 fluoboric acid; a copper cyanide bath may be used. The body may be of wire and the coppering carried out continuously, the chemical baths alternating with distilled water baths.

Title: Improvements in the remote control and protection of electric motors
IPC: H02H7/00
Filed: 1950-01-10
Abstract: 669,607. Protective cut-out arrangements. BROOKE, W., and BALDWIN, H. T. Jan. 10, 1950. No. 592/50. Class 38 (v). A remote control protective system for the control of an electric motor B supplied by means of a trailing cable V ... Z such as in mines, has a relay K with a coil K2 shunted by a large capacity condenser n (e.g. of 500 microfarads) to enable the satisfactory operation of the relay on a low voltage half wave rectified supply. The motor B is started when a remote control switch G is moved from the "off" position r1 to the "start" position r2 so as to complete a circuit from a transformer secondary winding g2 through the coil K2 and condenser n, through pilot conductor Z, half wave rectifier m, switch G and earth continuity pilot conductor Z. The coil K2 is fully energized and closes relay contacts K1 to energize the closing coil d of the contactor C. The switch G is then moved into the "run" position r3 where it inserts a resistance p into the control circuit to reduce the excitation of the relay K to a level sufficient to keep it closed, but insufficient to reclose it should it have been opened. by a fault. In the event of the earth connection becoming unsatisfactory as indicated by a resistance a, the relay K opens to stop the motor. Should the pilot and earth conductors Y, Z become short-circuited or should an earth fault develop on conductor Y, the rectifier m is no longer in circuit and alternating current is applied to the coil K2 and condenser n. Under this condition the relay coil has a high impedance relative to the condenser and the excitation of relay is reduced so causing contacts K2 to open. The transformer g may be supplied by means of a voltage stabilizing transformer h and a current-limiting resistance b may be inserted in the control circuit. It is stated that the use of a large condenser n, which may have a capacity of 500 microfarads, permits the satisfactory operation of the relay in conjunction with the half wave rectifier from an alternating current supply of from 1 to 4 volts. Specifications 644,058 and 665,570 are referred to.
Patent GB-555292-A (GB)
Title: Improvements in the production of puckered and like fabrics
IPC: D06Q1/02
Filed: 1942-01-16
Abstract: 555,292. Treating fabrics containing artificial fibres &c. with liquids etc.; embossing &c. AMERICAN VISCOSE CORPORATION. Jan. 16, 1942, No. 653. Convention date, Aug. 6, 1941. [Classes 2 (ii) and 15 (ii)] [Also in Groups VIII and XVI] A fabric comprising stretched filaments or fibres of a co-polymer of vinyl chloride and vinyl acetate or a chlorinated co-polymer of these substances is pre-treated in selected areas or lines so as to modify the heat-susceptibility of the filaments, and the fabric is then subjected to a heat treatment of such duration and intensity as to effect differential shrinking between the pre-treated and untreated areas. The pre-treatment may be such as to increase the heat-susceptibility of the filaments e.g. it may be a treatment with a plasticizer which may be applied by hand painting, textile printing methods, spraying, or brushing through a stencil. The plasticizer may be dimethoxy ethyl phthalate, dimethylene glycol monomethyl ether, or methylene glycol dipropionate. The heat treatment may be applied uniformly to the fabric or to selected areas which may or may not be of the same size as the'areas subjected to the pre-treatment. The entire fabric may be placed in an atmosphere of heated air, or other gas or vapour, or it may be immersed in a heated liquid such as hot water or other non-solvent liquid. Instead of using a plasticizer, a wetting agent may be used for pretreating the selected portions of the fabric. This may be applied in the form of a solution, after which it is dried upon the fabric, or it may be applied in the form of a powder, in which case it is worked thoroughly into the filaments of the yarns at the desired areas. The wetting agent may be a sulphonated alkyl naphthalene, a fatty alcohol sulphate, or a sulphonated dicarboxylic ester such as dioctyl sulphosuccinate. The pre-treated fabric may be immersed in hot water for such a time that the pre-treated areas are impregnated to a greater extent and are shrunk to a greater extent than the untreated areas. Another form of pretreatment consists in applying a resist material such as a gum, wax, lacquer, or resin coating to selected areas of the fabric. The coating acts as a heat insulator, preventing shrinkage of the protected areas prior to the shrinkage of the unprotected areas. The coating may be watersoluble provided that it is not completely removed by the heat-treating fluid before shrinkage of the unprotected areas has occurred. The differential shrinking of the fabric produces a puckered or ruffled effect. Specification 554,383 is referred to. The Specification as open to inspection under Sect. 91 describes also the treatment of fabrics containing other thermoplastic fibres, e.g. cellulose derivatives, and the application of heat to the fabric by contacting it with a heated engraved roller, or a tool with a blunt heated point which is drawn over the fabric by hand. This subject-matter does not appear in the Specification as accepted.

The driving gear and wheel are arranged for effecting repairs at sea, an air lock heing provided on the compartment containing the gears for this purpose. A gear box 51, Fig. 7, driven by gears 103, 102 from the engine, or by an electric transmission, drives a hollow shaft 59 through splines 60, this shaft having a plate 61 upon which are the hollow supports 62 of the paddle roots. The plate 61 is continued to form a flange 64 to which is attached a rim 65 adapted to form a continuation of the hull surface 32. The mechanism is supported by a casting 34, which with the flanged facing 30 fits in and on the opening in the hull. A central shaft 67 has at its base a spur wheel 139 which gears with a wheel 138 on the root 143 of each blade 142 for feathering it, such shaft at the upper end having an internal spur wheel 106 which is geared to a central shaft capable of adjustment for altering the phase of the feathering. This adjustment is effected by the wheel 124 which carries a pinion 113 operating gearing on a worm and worm wheel drive 110, of which the worm wheel is on the shaft to be adjusted. For lifting the gear, and after the upper casing has been removed, an eyebolt is screwed into the plug 94. The blades 142 are attached to a hollow root having a division plate and orifices 154, 155, whereby water is admitted for lubricating the lignum vitae bushes employed. The roots are supported in the tubes 62 by nuts 145. The blades are proportioned in the manner described in Specification 189,751. More than one paddle wheel may be installed, and in submarines the wheels may be placed at the sides for regulating immersion. When an electric transmission is employed, the rotor coils 187, Fig. 22, are fixed to the casing instead of the gears 103 and are surrounded by the fixed coils 188. A paddle wheel installation enables a full stern hull to be used as indicated in full lines in Figs. 3 and 4, as compared with the finer dotted lines required for a screw propeller installation.

Title: Improvements in or relating to two-line lubricating systems
IPC: F16N25/02
Filed: 1957-01-09
Abstract: 811,190. Reciprocating pumps. SCHLOSSHAUER, A. R. Jan. 9, 1957 [Jan. 9, 1956], No. 875/57. Class 102(1). [Also in Group XXXIV] A two-line lubricating system comprises a pump 1, having twin pistons 5, 6 and a piston valve 14, which feeds lubricant to a distributor unit 20. The pistons 5, 6 are connected to a pivoted lever 37 and when piston 6 descends it forces lubricant into a horizontal bore 13 containing the piston valve 14. The latter is then moved to the left and the lubricant passes through a conduit 18 to the distributor unit 20 forcing the pistons 39, 41 to the left in turn and ejecting lubricant through ports 29, 28 and 27 respectively. Lubricant passes from ports 27, 28 to lubricating points via conduits 46, 48 respectively and the lubricant from port 29 returns to the reservoir through conduit 19, annular passage 15 and conduits 16, 17. Lubricant from the end distributor 23 passes to a return valve 32, moves a piston 34 therein to the left and returns to the reservoir through a conduit 35 and a sight glass 36. The movement of the piston 34 to the left expels lubricant to a lubricating point via conduits 30, 43 and 44. If the lever 38 is moved to the other position the piston 5 forces lubricant into the passage 13 thereby causing the valve 14 and pistons 39, 41 and 34 to move to the right and lubricant to be expelled through conduits 45, 47 and 49. Lubricant is supplied on the suction strokes of pistons 5, 6 through conduits 9, 10 respectively. Specification 784,323 [Group XXXIV] is referred to.

Title: Improvements in or connected with means for separating air, vapour and volatile fluids from liquids
IPC: B01D19/00
Filed: 1928-01-11
Abstract: 308,010. Dodson, E. Jan. 11, 1928. Recovering oils and waste lubricants. -Air, vapour, and volatile impurities are separated from oil by circulating it through a Venturi tube B and providing beyond the tube an enlarged chamber D provided with a vent opening G controlled by a float-operated valve F. The reduction in pressure at the throat of the tube B causes the separation of the air &c. into bubbles which rise into the chamber D. A conduit H communicating with the atmosphere through a trap J leads to the throat, whereby air is drawn in to assist the separation. The trap J contains a float-operated valve J<2> controlling the air inlet, whereby liquid cannot escape through the trap when the pressure reduction in the tube B is insufficient. The tube B is provided with a heating jacket K to facilitate the separation. The invention may be applied to the separation of benzole from oil, or to lubricating systems of internal - combustion engines. In the latter case, the separated air and vapour may escape to the atmosphere, may be led to the induction pipe, or may be led to a hydrostatic gauge.
