Title: Improvements in the treatment or production of cellulose derivative materials
IPC: D06P3/40
Filed: 1929-07-09
Abstract: 336,621. Dreyfus, H. July 9, 1929. Yarns &c., treating with liquids, gases, and vapours.-For mordanting and weighting of materials made of or containing cellulose acetate or other organic esters of cellulose or of cellulose ethers, the mordanting or weighting metal radicle or a precipitant therefor is incorporated in the spinning solution; and the formed filaments are subjected to a treatment either in the course of their production or continuously with their production or subsequently thereto such as will fix the metal on the materials Metals that may be so introduced are aluminium, chromium, iron, tin, zinc, tungsten and bismuth If to the spinning solution there is added a precipitant such as tannic acid then it is preferred to apply the metal to the finished materials or to the materials continuously with their productions under such conditions that swelling of the cellulose derivative takes place, for example, by emploving the methods of Specification 258,874, 259 899. 281,084, 284,798 and 285,941. With the preferred method, namely, that in which the metal radicle is incorporated with the spinning solution, the following are examples of salts that may be used :-stannic chloride and thiocyanate, ferric chloride and thiocyanate, aluminium and chromium thiocyanates, and zinc chloride; and as precipitant there may be used sodium phosphate solution or water containing alkali such as ammonia or soda ash, although in the case of the mordant metals water by itself may be employed. The precipitant may be applied to the finished threads, yarns, fabrics, &c., or the threads may be treated therewith as they leave the spinning cells, or the precipitant may be incorporated in the coagulation bath or in a subsequent treatment bath. The acetylation solutions as obtained by the processes of Specifications 308,322, 308,323, 309,201; 312,095, 312,096, and 312,098, [all in Class 2 (ii), Cellulose &c.], may be used for spinning since these already contain the metal radicle, the mineral acid being, if desired, first neutralized by sodium acetate and the excess of anhydride being destroyed by the addition of dilute acetic acid. Such solutions are conveniently spun into dilute acetic acid, and the metal fixed by carrying the filaments into a soda ash bath or by subsequent treatment with such a bath. Mordant or other dyestuffs may be added to the coagulation or fixing baths. Specifications 323,501 and 323,785 are referred to.

Title: An electrolytic method for the production of titanium metal
IPC: C25C3/28
Filed: 1953-07-30
Abstract: 740,849. Electrolytic production of titanium metal. HORIZONS TITANIUM CORPORATION. July 30, 1953 [Oct. 8, 1952], No. 21180/53. Class 41. A method of producing titanium metal by electrolysis of titanium monoxide in a fused salt diluent bath composed essentially of at least one alkali metal halide other than alkali metal fluoride, comprises adding to the bath prior to the electrolysis 2 to 30 per cent of an alkali metal fluotitanate by weight of the bath. The alkali metal halide may be sodium or potassium chloride or mixtures of these salts, and the fluotitanate may be sodium or potassium fluotitanate, or mixtures thereof. The fluotitanate may be formed in the bath by adding a stoichiometric amount of sodium or potassium fluoride and then introducing titanium tetrafluoride. The electrolysis, which should be carried out in an inert atmosphere, may take place in a cell comprising a graphite crucible as anode and a centrally disposed iron cathode. As carbon monoxide is formed at the anode by reaction with the carbon anode, and such carbon monoxide may form titanium carbide with deposited titanium, a cell may be used which is divided by a partition into an anode compartment having a graphite anode, and a cathode compartment having an iron cathode, titanium monoxide being introduced into the anode compartment and confined there until dissolved. Another cell used comprises a graphite crucible, as anode, having an inner false wall made of graphite bored with small holes. Titanium monoxide is introduced into the bath in the annular space between the crucible wall and the inner false wall. The cathode is located in the centre of the crucible. A further apparatus employs a porous hollow graphite anode, into which titanium monoxide is fed. Specifications 701,288, 711,077 and 735,597, [both in Croup III], are referred to.

Filed: 1944-10-30
Abstract: 587,293. Band clips. MARCONI'S WIRELESS TELEGRAPH CO., Ltd. Oct. 30, 1944, No. 21200. Convention date, Oct. 30, 1943. [Class 44] [Also in Groups XXXVI and XL] The ends of a band clip are engaged by a cam which may be operated to tighten the band by a screw or the like arranged between the ends. As applied to holding a thermionic valve 3 to a chassis 1, the band clip 7 encircles the base 5 of the valve and has outwardly extending parts 7a, 7b which are drawn together by the wedging action of a V-shaped cam member 17 when a screw 13 is turned by a screwdriver 19. A projection 13b on the screw causes the cam 17 to follow the screw when it is being unscrewed. The parts 7a, 7b are preferably bent to the same angle of tilt as that of the sides of the cam 17, and preferably have outwardly bent extremities 7x, 7y to hold the cam 17 against undesired movement. The band clip 7 may rest on the chassis or may be supported on feet 9a, 9b, 9c, 9d. The two latter are secured to the chassis by screws 11c, 11d, whilst the two former are free to slide on the surface of the chassis.

Abstract: 1,176,905. Battery charging systems. YUASA BATTERY CO. Ltd. 3 May, 1968, No. 21220/68. Heading H2H. [Also in Division H1] A control element 3 provided in parallel with a battery 4 undergoing charging comprises a series of PN junction-containing Si wafers soldered together by a material containing Pb and preferably Sn as its major constituents (see Division H1). The element 3 has a negative resistance characteristic due to the retention of heat generated towards the centre of the series of wafers by current passing therethrough, and gives protection against excess charging current as well as providing a trickle charge for the battery when it attains the required voltage. Types of batteries referred to are sealed nickel-cadmium alkaline batteries and sealed lead batteries. The optimum number and characteristics of the Si wafers are determined by the required voltage of the fully charged battery. As shown, a diode 16 may be placed in series with the battery 4 to prevent discharge through the control element 3 in the event of overheating. A voltage compensating diode 17 is also required in this case. The diodes 16, 17 may be incorporated into the same encapsulation as the element 3.

Title: Improvements in or relating to parallel knitting-machines
IPC: D04B7/04
Filed: 1922-08-04
Abstract: 186,313. Marneux (nÚe David) L. Sept. 23, 1921, [Convention date]. Parallel machines; knitted fabrics,-An attachment whereby fabrics with vertical stripes or with checked effects can be knitted on one face of a ribbed fabric comprises a pair of rotary toothed wheels 28, 29 which act in alternation upon the butts of the needles in one bed and cause the needles engaged by the upstanding parts of the wheels to cast off their loops. The wheel 28 may be arranged to act upon a group of three needles in the front bed, miss the next four needles and so on. In that case the wheel 29 is arranged to act in a subsequent course, upon the groups of four needles missed by the wheel 28. By changing the yarn for one of a different colour previous to an operation of the wheel 29 coloured vertical stripes are obtained. If after knitting a few courses of striped fabric the yarn is not changed previous to an operation of the wheel 29 but is changed previous to subsequent operations, a checked effect is obtained. The wheels 28, 29 may be replaced by others giving different widths of stripes &c. The wheels 28, 29 are mounted loosely on a part 31 which is rotatable by means of a handle. 36 on an horizontal journal 34 with two flats 37 which co-operate with springs 38 and allow the device to be turned through half a revolution each time. The inner side of each wheel has four recesses 42 which co-operate with spring-pressed pawls, and position each wheel correctly. When a wheel is required to operate on the needles, the corresponding pawl is disengaged from its recess 42 by means of a striker on the machine frame which engages a notch 48, 49 in a rocker 43, pivoted at 44, and frees the wheel. On the return movement of the cam carriage the same striker reverses the operation and causes the wheel to be locked by its pawl.
