Filed: 1955-09-14
Abstract: 813,633. Lift trucks. HYSTER CO. Sept. 14, 1955 [Sept. 30, 1954], No. 26338/55. Class 78 (3). A lift truck is provided with a single telescopic tubular mast 18, 19 on which a lifting carriage 20 is guided by rollers 117, 127 and further rollers (not shown) engaging the sides of the mast. The tubes 18, 19, which are of rectangular section, contain the lifting ram 51, 53 and are slotted at 61, 63 to permit the pulley 57 to rise relative to the tubes to provide an initial lift of the carriage to the position shown without extension of the mast. Guides 71 on tube 18 engage the axle 59 thereby transmitting to tube 18 any bending stresses which would otherwise act on the ram during this initial lift. When the parts reach the position shown a projection 73 on a pulley supporting box 55 mates with a hole in plate 45 and further supports the ram against bending. The lower end of the mast is supported on a plate 17 which is tiltable about the front wheel axle (not shown) by means of a thrustor 27 and a pair of arms 21. In a modification (Fig. 11, not shown) the box 55 is permanently attached to plate 45. In another modification (Fig. 10, not shown) the tubes 18, 19 are of circular cross-section and are keyed together to prevent rotation ; the outer tube being provided with diametrically opposed guide rails engaging rollers on the lifting carriage. In a further modification (Fig. 12, not shown) the transverse members of the carriage are recessed to accommodate the mast so reducing the overhang of the load.

Title: A process for the recovery of reduction products of titanium tetrachloride
IPC: C25C3/28
Filed: 1960-07-29
Abstract: 915,966. Electrolytic production of titanium and lower chlorides thereof. LONZA ELECTRIC & CHEMICAL WORKS Ltd. July 29, 1960 [July 31, 1959], No. 26486/60. Class 41. At least one reduction product of titanium tetrachloride, namely titanium or its di- or trichloride, is produced by the electrolysis of a melt divided by a diaphragm into an anolyte and a catholyte and containing at least one alkali and/or alkaline earth metal chloride together with at least one titanium salt, preferably a chloride, whereby the effective surface of at least one cathode is in continuously repeating sequence alternately placed in contact first with the melt where a thin layer of a substance, such as alkali metal(s), titanium or TiCl 2 , having a reducing action on TiCl 4 , is electrolytically precipitated, and then with a gas at least partially containing TiCl 4  where the substance reacts with the TiCl 4  to form a reduction product containing Ti and Cl in a lower chlorination stage, which in the ensuing stage is dissolved in the melt where the substance having a reducing action is again precipitated on the cathode surface. For example (see Fig. 1) the diaphragm D, made of granular ceramic, quartz, graphite or glass, may be the bottom of a tube C placed inside a vessel B, both being of similar material, which is half-filled with a LiCl-KCl eutectic melt J maintained at 600 ‹ C. (heating means, not shown). The tube C contains a cathode K 1  of graphite or titanium and two reciprocating grooved graphite cathodes K 2  and K 3  (actuated by moving connecting leads through seal) and has inlet pipes F and G for gaseous TiCl 4  and argon and an outlet pipe H. Outside the tube C there projects into B a number of graphite anodes A (only one shown); pipe L is for chlorine discharged at the anodes. K 2  and K 3  initially receive a potential of - 5 volts, with respect to anodes A, for precipitating Li and K on to the cathodes; K 1  receives a potential of - 3.5 volts sufficient for precipitating Ti but not Li or K. By alternately dipping the cathodes K 2  and K 3  into the melt and raising them into the gas space above, a continuous enrichment of the melt with TiCl 2  and TiCl 3  is obtained with an increased precipitation on K 2  and K 3  of titanium instead of Li and K; thus Ti assumes function of reducing agent. For producing only TiCl 2  and TiCl 3  or if K 2  and K 3  only receive a potential of - 3.5 volts, cathode K 1  is not needed. Disc-shaped or cylindrical cathodes rotating about a horizontal axis may be used instead of reciprocating ones, or the cathodes may be stationary and the melt and gas jointly rotated.

Title: Improvements in or relating to refrigerant compressor
IPC: F04B39/12
Filed: 1955-09-16
Abstract: 780,053. Compressors. GARRETT CORPORATION. Sept. 16, 1955 [Sept. 24, 1954], No. 26552/55. Class 8(1). In a refrigerant compressor having a casing 10, a piston 14 reciprocating in a cylinder 17 with valves 18 and 19 communicating with the gas inlet 20 and compressed gas outlet 21 respectively, and a check valve 25 permitting gas to flow from the casing to the inlet, droplets of oil in the gas in the inlet 20 collect in a sump 23 having an orifice which allows oil in the sump to return to the casing when a pressure differential exists across the orifice. The orifice may communicate directly between the sump and the casing, or as in Fig. 1, the orifice 22 may be located in the cylinder 17 so that it is passed by the piston 14 in its extreme compression stroke position. During the intake stroke of the piston, its movement, towards the casing 10 causes a compression of gas therein which is relieved by the valve 25 opening to permit flow of gas around the baffle 26 and into the inlet passage 20. During its compression stroke the piston creates a partial vacuum in the casing 10 so that as soon as the orifice 10 is uncovered the pressure differential which exists across same will force oil in the sump 23 into cylinder 17 and casing 10.

Title: Improved process of proofing or sizing paper or cardboard with paraffin in course of machine manufacture of said paper or cardboard
IPC: D21H23/50
Filed: 1932-09-26
Abstract: 406,771. Sizing or waterproofing paper or cardboard. THIRIET, A., and MEYER, J., Voiron, Isere, France. Sept. 26, 1932, No. 26694. [Classes 96 and 140.] Sized or waterproofed paper or cardboard is made by applying fused paraffin wax, or a composition containing fused paraffin wax, to paper or cardboard strip immediately or shortly before the last drying cylinder of the machine on which the paper or cardboard is manufactured ; the paraffin is deposited on the strip by transfer, brushing or spraying. In applying the paraffin by transfer, the strip may be passed over a roller, or between two rollers, to which paraffin is supplied by another roller dipping into fused paraffin ; the amount of paraffin supplied can be regulated by varying the circumferential speed of the roller or the rate of travel of the strip. Alternatively, a roller in contact with the strip may contact with a strip of felt to which fused paraffin is supplied in adjustable amount by a roller dipping into paraffin or by a pump, and as further alternatives a pump may be used to supply fused paraffin directly to the rollers or to a feltcovered roller contacting with one of the drier cylinders (other than the last cylinder) of the machine. In applying the paraffin to the strip by brushing, the paraffin may be applied to the strip independently of the brush or by the brush. The paraffin may also be applied by spraying it on to the strip in a chamber through which the strip is passed. The conditions may be such that only one side of the strip is affected, or the strip may finally be heated for a sufficient time to cause uniform diffusion of the paraffin into the strip. Specification 293,000, [Class 96], is referred to.

Patent GB-366963-A (GB)
Title: Improvements in the manufacture of solutions of fibroin
IPC: D01F4/00
Filed: 1930-09-10
Abstract: Copper-ammonium solutions for dissolving fibroin contain more than 4 molecules of ammonia to 1 atom of copper.  If copper salts are used for the preparation of the solutions, sufficient alkali must be used to convert all the copper into hydroxide, but excess of alkali should be avoided.  In examples (1) a copper hydroxide paste is dissolved in 10 per cent ammonia, the solution being cooled to -- 5 DEG  C.; (2) copper sulphate is dissolved in ammonia solution, and caustic soda solution is added, the solution being cooled to -- 15 DEG  C. and filtered to remove sodium sulphate.ALSO:Fibroin is dissolved in a cuprammonia solution containing more than 4 molecules of ammonia to one atom of copper at a temperature below 0 DEG  C., preferably 0 to --15 DEG  C., and the solution is maintained at such temperature during any further steps in its preparation where practicable, and during its storage if any.  A solution is thus obtained of high viscosity, suitable for the production of artificial silk.  To prevent degradation of the fibroin it is advisable to treat the solution for the removal of some of the ammonia.  This may be effected by suction or by passing through the solution a current of an inert gas, preferably until the solution contains not more than two molecules of ammonia to one atom of copper, in which operation it may be necessary to raise the temperature to 25 DEG  C; or the fibroin complex may be precipitated from the solution by addition of salt solutions such as ammonium sulphate, sodium sulphate or sodium chloride, or organic liquids soluble in water such as methyl or ethyl alcohol or acetone, the precipitate being then redissolved in water. The quantity of copper hydroxide should be not more than 30 parts copper to 100 parts air-dry degummed fibroin.  This avoidance of an excess of copper allows of filtering the solution through a cellulose filter such as wadding without causing the filter mass to swell.  If copper salts are used for the preparation of the solution, there must be used sufficient alkali to convert all the copper into hydroxide, but excess of alkali should be avoided.  In examples (1) a copper hydroxide paste is dissolved in 10 per cent ammonia, the solution being cooled to -5 DEG  C.; degummed natural silk is added, and the whole is filtered and maintained at the same temperature; (2) copper sulphate is dissolved in ammonia solution, and caustic soda is added, the solution being cooled to -15 DEG  C. and filtered to remove sodium sulphate; degummed "frison" is added and dissolved with stirring, and a current of nitrogen is introduced while heating to 15-20 DEG  C.; the solution is filtered and led to the spinning machine; (3) the solution of "frison" made as described in the preceding example is treated with acetone instead of nitrogen; the precipitated mass is kneaded with acetone and then dissolved in water and filtered. Specification 366,987 is referred to.
