Title: Improvements in or relating to the manufacture of artificial filaments, threads, films, fabrics and the like
IPC: D01F2/28
Filed: 1932-02-26
Abstract: Artificial filaments, films, &c. of organic derivatives of cellulose, of modified properties, e.g. lustre, weight, heat resistance and the like, are obtained by incorporating therein an organic boron compound such as methyl borate, ethyl borate, or glycerine borate.  The boron compound is preferably incorporated into the spinning solution, either in solution or as a dispersion, and in the latter case, where grinding is employed, dispersing agents and/or protective colloids and/or oils or other liquids such as oleic acid, linseed, olive, or castor oil, diethylene glycol or heavy white mineral oil may also be added, during or after grinding.  When the boron compound is applied to the formed materials, swelling agents such as thiocyanates, alcohols, solution of formic or acetic acid, or the compounds described in Specifications 281,084 and 323,501, [both in Class 2 (ii), Cellulose &c.], are preferably present, for example, an alcoholic solution of a borate ester may be applied to the materials. The organic boron compound may be decomposed, either in the spinning solution, or in the materials, to produce other boron compounds, for example, ethyl borate dissolved in alcohol may be added to a solution of cellulose acetate in aqueous acetone whereby boric acid is formed in the spinning solution, or finished materials containing the borate ester may be treated with aqueous media. In an example, triethyl borate dissolved in alcohol is added to a cellulose acetate spinning solution which is spun into filaments. The latter are treated with water or dilute acid to give products containing boric acid. According to the Provisional Specification, boron compounds other than organic boron compounds, e.g. boric acid, or alkali metal or other metallic borates, may be employed.

Filed: 1934-02-23
Abstract: 433,953. Refrigerating. ALTENKIRCH, E., 56, Balmhofstrasse, Neuenhagen, near Berlin. Feb. 23, 1934, No. 5944. Convention date, Feb. 28, 1933. [Class 29] Absorption machines.-In a reversing system including two absorber-generators C and D each acting as an absorber when the other acts as a generator, an inert gas circulates in succession through the unit D which is generating, the condenser E, the unit C which is absorbing, the two parts F and G of the evaporator, and back to the unit D, the direction of flow being reversed when the units C and D change their functions. The condenser E may be byepassed by a connection H. Solid absorbents such as silica gel or charcoal may be used, and may be contained in narrow passages through thick discs, covered on both sides with wire gauze and spaced apart by annular washers within tubular vessels. If a liquid absorbent is used it may flow down from tray to tray in absorbergenerators L and M, Fig. 3. The pipes J conveying liquid refrigerant from the condenser E to the evaporator are formed to provide liquid seals. The apparatus may be worked by the heat of the sun, reversal being effected as the sun changes position during the day. In the construction shown in Fig. 3 a siphon R<1> discharges cooling water on one of the absorber generators. A tube R<2> connects the siphon with a bulb R<3> containing air. When the rays of the sun fall on this bulb the expansion of the air stops the siphon and reverses the operation of the machine automatically. Sulphur dioxide, methyl alcohol or water may be used as refrigerants with solid absorbents, and acetaldehyde or ethylamine as refrigerants with water as absorbent in apparatus at about atmospheric pressure. Argon, nitrogen and air are mentioned as neutral gases. The evaporators may be arranged in an insulated chamber B, Fig. 1, with the generator-absorber vessels outside the chamber walls and the condenser in a covered air flue or water tank on top of the chamber.

Filed: 1974-02-12
Abstract: 1425140 Over-running trailer brakes; hand actuation; transmitting mechanism GRAU BRAKE SYSTEM GmbH 12 Feb 1974  06262/74 Heading F2E An over running brake arrangement for a trailer comprises a brake linkage, an overrunning brake lever having a first arm which serves to operate the brake linkage and a second arm which is actuatable by over-running actuating means of the brake arrangement, a manual brake lever fulcrummed on the same pivot member as the over-running brake lever and having first and second arms, and manual actuating means which acts on the second arm of the manual brake lever, whereby the first arm of the manual brake lever acts on the brake linkage, the manual actuating means comprising a transmission device whose input can be rotated to effect movement of its output but wherein the reverse action (output to input) is not possible, and a hand crank for operating the device. As shown, the brake (not forming part of the drawings) may be applied in three ways; by over-running, in which case the end of the drawbar 2 of the towing vehicle moves backward relative to the shaft 1 attached to the trailer (assumed to be on the right) and swings an over-running lever 5 clockwise about pivot pin 4 to pull the brake on by linkage 6; by handcrank 15 which on rotation causes an output member 16 of a transmission device 17 to descend (but not rotate) thereby swinging a manual brake lever 7 clockwise about pivot pin 4 to pull the brake on by tension rod 10, spring unit 11, retaining yoke 12, abutment member 13 on linkage 6, and linkage 6; and by separation of the trailer from the towing vehicle, in consequence of which a line (not shown) attached to a spring ring 20 first swings a break-away safety lever 19 clockwise about pivot pin 4 and then breaks, the lever 19 applying the brake by engagement of its offset arm 20 behind arm 9 of lever 7 and being retained in the "brake-apply" position by a pawl-and-ratchet arrangement 24, 23. An alternative transmission device, Fig. 3, comprises a cylinder 25 closed at the top by a plate 27, prevented from rotating by a boss 30 engaging a slot 31 in a fixed housing 17, and moved up or down only by rotation of threaded spindle 29 by detachable hand crank 15. Plate 27 acts through springs on a retaining cup 26 integral with an output member 16 having slotted engagement with a cam surface 18 on arm 8 of manual brake lever 7.

Filed: 1972-02-10
Abstract: 1349622 Actuators PNEUMO DYNAMICS CORP 10 Feb 1972 [26 April 1971] 6340/72 Heading B8J A linear actuator 1 comprises a housing 2 with a sleeve 3 projecting from one end 4 thereof, the sleeve being connected to a mounting bracket 7 by a ball 5 and socket 6 arrangement. A screw shaft 8 of ball screw or high lead acme screw-type is contained within the sleeve 3 and projects from the other end 9 of the housing 2 with a clevis 10 for attachment to the load (not shown) which prevents rotation of the screw shaft 8. A nut 11 engages the screw shaft 8 and is driven from an input shaft 12 through spur gears 13, 14. A direction-sensitive clutch 15 comprising clutch rollers 16 in cam slots 17 in clutch element 18 prevents back driving or overhauling of the actuator 1 by the applied load in the opposite direction and coacts with a friction bearing 22 co-operating with inturned flange 21 on sleeve 19 surrounding the clutch element 18. Interposed between the flange 21 and a thrust washer 28 is a needle bearing 24 so that when the nut 11 is rotated in a clutch disengaging direction causing outward movement of the screw shaft 8 against a compression load, the nut 11 and clutch element 18 are free to rotate relative to the sleeve 19, thrust loads being taken by the bearing 24. Inward movement of the screw shaft 8 is thus prevented except when a net positive input torque is applied to the nut 11 by the shaft 12 for positive control in the inward sense. If the load on the actuator is in tension instead of compression the actuator connections may be reversed or the clutch and friction bearing located at the other end of the housing, Fig. 3 (not shown). Bi-directional braking may be provided by two clutch and friction bearings arranged at either end of the housing, Fig. 4 (not shown).
