Title: Process and apparatus for the production of textured textile slub yarns
IPC: D02G1/02
Filed: 1966-02-16
Abstract: 1,120,196. Finishing yarns. HEBERLEIN & CO. A.G. 16 Feb., 1966 [17 Feb., 1965], No. 6821/66. Headings D1D, D1F and D1W. Monofilament, multifilament or staple fibre yarns of thermoplastic material e.g. a polyamide, polyester, vinyl polymer or copolymer (polyacrylonitrile), polyolefin or cellulose acetate, or mixed yarns of thermoplastic fibres non-thermoplastic natural fibres are converted to textured, stub yarns by passing them through two or more spaced guides and temporarily high-twisting two or more of the yarns together in such manner that the point of union of the travelling yarns traverses between limits or follows a circular path so that the yarns undergo reciprocal high-twisting about each other in sequence at the union point i.e. each yarn is periodically a core around which the other yarns twist and then twists (perhaps with one or more other yarns) about the other, or another, yarn, setting e.g. by heating the intertwisted assembly and then separating the individual yarns. The resultant yarn comprises, along the length thereof, periodically recurring stubs between transitional sections Which merge into unstubbed, simply twisted sections, Figs. 4 and 5 (not shown). As shown, yarns 11, 12, 13, 14, are advanced by rollers 3, 4, and pass through eyes, disposed at the four corners of a square, in a disc 19 and are intertwisted at a point 15 which rotates, in consequence of differences of tension and the number of twists in the yarn and the torque acting on the united yarns, to effect the changing pattern of intertwist. The intertwisted assembly then passes through a guide 16 and heater 17 to a separation point 18 where the assembly is divided into individual yarns by a falsetwister (which also imparts the temporary high-twist) or a device for separating yarns (previously twisted together along a section) by continuously drawing them apart.

Patent GB-691225-A (GB)
Title: Improvements relating to fluid pressure braking apparatus
IPC: B60T15/30
Filed: 1951-03-22
Abstract: 691,225. Fluid-pressure brakes. WESTING- HOUSE BRAKE & SIGNAL CO., Ltd., and SIMMONS, A. W. Jan. 1, 1952 [March 22, 1951], No. 6866/51. Class 103 (i). The accelerator or quick-service bulb 15 of a distributer valve for fluid pressure braking apparatus is adapted to be charged through a quick-service valve 21 and to exhaust through an auxiliary valve 13 which is opened by the piston 1 of the quick inshot valve when in its uppermost position. The quick service valve 21 is normally kept closed by a spring 27 and may be opened by auxiliary reservoir pressure in chamber 25 on one side of the diaphragm 22 acting in opposition to brake pipe pressure in chamber 23 on the other side of the diaphragm. When a vehicle has been cut out of a train with its brakes applied, there may be sufficient pressure left in the auxiliary reservoir to keep the valve 21 open. Therefore when charging is commenced through the brake pipe, air will be able to escape to atmosphere through passage 20, the quick service bulb 15, choke 18, passages 19, 14, open valve 13 and passage 11 until such pressure is reached that the piston 1 of the quick inshot valve moves down and closes valve 13. To avoid this loss of air during the initial charging period a check valve 16 is inserted between passages 14 and 19, spring-loaded so that it will not open until the brake-pipe pressure has become sufficient to cause the quick inshot valve to close valve 13.

Title: Tape dispenser and applier
IPC: B65B51/06
Filed: 1950-03-20
Abstract: 668,973. Tape-dispensing devices. BETTER PACKAGES, Inc. March 20, 1950 [March 19, 1949], No. 6897/50. Class 73. A machine for applying adhesive tape to cartons has a table, mounting a movable abutment against which a carton is pressed, solenoid operated means for advancing a predetermined length of tape and severing it from the supply, and means for applying the tape progressively against two sides of the carton. Tape is supplied from a roll 28 and fed upward, to project through a slot 66 in a work supporting table 68, by a reciprocating feeding head 40 having a tape gripping cam acting on the up stroke. The head 40 is connected by links 86 to levers 78 pivoted at 80 which are urged upwards by a spring 90 for the feeding stroke, their movement being limited by an adjustable buffer 149 engaging a fixed bar 144, and lowered by a plunger 72 of a solenoid 70. A latch 108 pivoted at 106 to a lever 102 and urged clockwise by a spring 116 is engaged by the downward movement of a pin 112 carried by the levers 78 to force the lever 102 clockwise and through a link 100 to operate a tape severing blade. The solenoid 70 is actuated through a solenoid 186 by closing a switch 180, when a trip lever 170 is depressed by a carton placed on the table 68. A resilient abutment is mounted in a casing 124 and has a ball and socket connection to a push rod 128 controlled by a spring 130 to keep it approximately in line with the rod which slides in guides 134, 136 and has a cross head 138 limiting the forward motion caused by a spring 142. A tape moistening brush 62 is provided. In operation, a carton pushed against the abutment engages the projecting strip on one side withdrawing the remainder of the predetermined severed length of tape through the slot 66 so that it is wiped on the underside of the carton by resiliently mounted rollers 150. The carton has depressed the trip lever 170 and actuated the solenoid 70 to lower the feeding head 40 the lever 170, being held down by a trigger 190 which is pushed forward by a holding solenoid 200, to engage under a lever 182, when a switch 202 is closed by depression of a cam 204 as it leaves a depression 206 of the push rod 128 as it is pushed back by the carton. On removal of the carton the abutment returns opening the switch 202 of the holding solenoid 200 which thus breaks the circuit of the solenoid 70 allowing the feeding head 40 to rise under the action of the spring 90 to feed and sever a fresh length of tape.

IPC: C10G29/12
Filed: 1950-03-21
Abstract: Petroleum hydrocarbon fractions are sweetened by treating with an aqueous solution of an alkali metal hypochlorite containing not less than 90 grams per litre of an alkali metal hydroxide.  The hydrocarbon fractions may be those boiling below 700 DEG  F. and may range from liquefied petroleum gases such as propane, butane, pentane and pentylene to gasoline; kerosene, diesel oil and heating oil; they may be derived from crude petroleum or from thermal or catalytic cracking operations.  The hydrocarbons are preferably treated with not more than 20 per cent. by volume of a sodium hypochlorite solution containing not more than 60 grams of hypochlorite per litre. From 50-200 grams of a chloride, for example sodium chloride, may also be added to the hypochlorite solution.  The spent hypochlorite solution may be decomposed with steam and the sodium hydroxide solution formed may be recycled to a preliminary washing zone for the removal of hydrogen sulphide from the hydrocarbons.  The mercaptan free hydrocarbons may be further treated, for example with an aqueous solution of tetraethanol ammonium hydroxide, or with doctor solution; they may also be treated with alcoholic solutions of alkali metal hydroxide before or after the hypochlorite treatment.
