Title: Improvements relating to electrical heating apparatus
IPC: H05B6/06
Filed: 1945-02-26
Abstract: 594,317. Induction heating. MORRIS MOTORS, Ltd., BRIDLE, J. H. and BROWN, R. J. Feb. 26, 1945, No. 4772. [Class 39 (iii)] [Also in Group XXXV] In an electrical heating system for an industrial operation such as the case-hardening of steel workpieces, the current to a highfrequency heating coil a, Figs. 1 and 2, surrounding the workpiece b on a work support comprising a pair of heat-resisting sheets d each pivoted at a point f, is terminated by an electronic timing means v which is also effective at the same time to operate the work support to allow the workpiece to fall into a quenching tank q below the heating coil a. Heating is initiated by the momentary closure of a manually-operated switch x, Fig. 3, which energizes the magnet coil 2 over normally closed switch contacts r associated with the magnet coil t, to close the switch contacts w against the pull of a spring 3 and thus energize the oscillation generator v which then supplies H.F. current to the heating coil a. After an interval determined by the timing means u, the magnet coil t is energized to open the switch contacts r, removing the short circuit from the magnet coil o which is then connected in series with the coil 2 and energized to close the switch contacts n, against a spring p. The voltage across coil 2 is then insufficient to maintain switch contacts w closed, which opens under the action of spring 3 to terminate current in coil a. Simultaneously, coil i is energized to move the heat resisting sheets d through the arms e of a scissors like mechanism to allow the workpiece to drop into a quenching tank c. A. spring- loaded plunger 4, Fig. 1, expedites the expulsion of the workpiece and may be adapted to centralize and hold the workpiece in the coil during the heating period. A dashpot q, associates with switch contacts n, controls the rate of opening of this switch. The magnet coil i may be utilized in alternative arrangements to hold the workpiece in the heating coil a during the heating period and release it into the tank after a predetermined time, in which case switch n is normally closed; or to operate a water valve for quenching purposes or adapted to control an automatic workfeeding mechanism to coil a.

Title: Improvements in Bottle Feeding Mechanism for use with Bottle Washing and Filling Machines.
Inventor: THORNTON ALFRED AUGUSTUS
IPC: B08B9/44
Filed: 1916-04-05
Abstract: 101,443. Thornton, A. A., (Barry-Wehmiller Machinery Co.). April 5, 1916. Bottles, washing.-A transferring-apparatus, for receiving bottles in an inclined position from a washing-machine and depositing them in an upright position on a table, comprises a series of bell-crank levers mounted on a rocking shaft 40. In the receiving position, the arms 45, 46 of the levers engage the bottoms and sides of the bottles respectively as they slide down the wire grid A from the washing-machine. During the first part of the rocking movement of the shaft 40, the bottles are supported by both arms until their bases contact with the table B, but afterwards the arms 45 continue their downward movement, and the ends of the arms 46 push the bottles along the table far enough for the succeeding bottles to be deposited. The rocking-movement is obtained primarily by the rotation of a crank 56 on the main driving-shaft 10 of the washing- machine, which actuates a connecting-rod 57 connected to the oscillating crank 53. The horizontal component of the motion of the rod 57 is transmitted through links to the spring-controlled rod 49, which carries a rack 70 gearing with a pinion at one end of the shaft 40. The grid A is carried by side members pivoted at 24 and adjustably fixed by pin-and-slot mechanism 26 to frame members 25, which in turn are adjustable in slots 29. Each bar of the grid is V-shaped, and the lower horizontal member 19' is bolted to a cross-bar connecting the side members. The table B may be adjusted angularly about the trunnions 31, by means of which it is secured by split screw sockets to the arms 30, and also may be raised and lowered by rotating the arms 30 on sleeves surrounding the shaft 40. The transferring-apparatus is shown applied to a washing-machine in which bottle-supports are carried on an endless chain, which is moved forward one step each time the crank 11 engages a slot in the wheel 8. A plate 15 prevents premature discharge of the bottles.

Title: Process for the recovery of germanium values
Inventor: ZIEGENBALG SIEGFRIED
IPC: C01G17/00
Filed: 1960-02-12
Abstract: Germanium values are recovered from neutral or weakly acidic (up to 1N) cold or hot aqueous solutions containing up to 5 g.p.l. germanium, by means of positively charged porous synthetic adsorption resin ion exchangers, characterized in that the ion exchanger is first charged with a water-soluble complex forming agent which contains phenolic hydroxyl groups and can be adsorbed on the ion exchanger and is also able to form germanium complexes, wherein the solutions are passed through the ion exchanger, the germanium being selectively bound as a complex.  The germanium may then be eluted by means of hydrochloric acid of a concentration greater than 7N.  The germanium tetrachloride may then be recovered from the eluate by continuous distillation, preferably employing a carrier gas, and, preferably after having been freed of HCl vapour, may be converted to the dioxide.  In an example, Wofatit E was charged with tannin as the complex forming agent ("Wofatit" is a Registered Trade Mark) and a 0,2N sulphuric acid electrolyte solution containing germanium contaminated with zinc and arsenic was passed through.  The resin was eluted with 10N.NCl and the eluate distilled.  The germanium tetrachloride vapour was passed through ferric chloride solution to remove arsenic and then hydrolysed to form a germanium dioxide.

Title: Improvements in a device for mechanically setting up account sheets in typewriters with cylindrical platen
IPC: B41J11/36
Filed: 1946-02-19
Abstract: 616,287. Typewriters. PAILLARD & CIE., SOC. ANON., E. Feb. 19, 1946, No. 5171. Convention date, March 13, 1945. Addition to 590,967. [Class 100(iv)] In the device described in the parent Specification for feeding independently account sheets with reference to a journal sheet carried directly by the platen of a typewriter in order to position the account sheets correctly, key-set devices are provided for selecting the position to which the account sheet is moved to bring a particular line thereon into register for duplicating its matter on the journal sheet. The keys 55 are pivoted at 54 in recesses 52 formed in a casing 50 in the shape of a sector of a cylinder and attached to one of the side plates 10 of the positioning device. Each key 55 has a downwardly-projecting arm 56 provided on one side with a lug 57 limiting the upward movement of the key under the action of a spring 53a and on the other side a tooth 58. A sector-shaped member 61 pivoted at 62 has a rim 64 which under the action of a spring 63 normally engages all the arms 56 below the teeth 58. If a key is depressed, the rim 64 engages its tooth 58 and holds it down until another key is depressed. Two shafts 29, 30 which are operated by cranks to position two account sheets as described in the parent Specification, have fixed thereto levers 65, 66, respectively the former of which is connected by a link 70 to a lever 66a similar to the lever 66 and freely mounted on the shaft 30. A spring-pressed pawl 67 is pivoted to the end of each lever 66, 66a and is adapted to engage the end 60 of a depressed key 55 when the levers are rotated. Thus, depression of a key determines the amount of rotation which can be imparted to the shafts 29, 30 so that actuation of a particular key causes a corresponding line on the account sheet to be brought to the required position. More than two account sheets may be accommodated, if desired. According to the Specification as open to inspection under Sect. 91, the operating cranks may both be carried by the shaft 30 and the shaft 29 disposed with. This subject-matter does not appear in the Specification as accepted.

Title: Improvements in the manufacture and production of pure benzoic acid
IPC: C07C51/487
Filed: 1929-02-18
Abstract: 329,375. I. G. Farbenindustrie Akt.- Ges. Feb. 18, 1929. Addition to 307,343. Benzoic acid; phthalic acid.-Specific or modified methods are described for effecting the process of the parent Specification, according to which benzoic acid contaminated with naphthoquinones and phthalic anhydride is purified by reducing the naphthoquinones, e.g. with bisulphite, and hydrating the anhydride, the converted impurities being then leached out with water. Specific methods now described for putting the process into effect comprise (1) effecting the reduction with a metal and an acid and/or (2) effecting the reduction with the crude benzoic acid in the fused state or dissolved in an inert organic solvent not miscible with water, and simultaneously or subsequently treating with an aqueous solution or suspension of an acid-binding agent in an amount corresponding to that of the phthalic acid. Suitable acid-binding agents are salts of volatile acids which react with phthalic acid but not with benzoic acid under the reaction conditions; accordingly sodium bisulphite may serve as both the reducing and the acid-binding agent. The benzoic acid may be further purified by treatment with active carbon and recrystallization, or alkali-metal benzoates prepared from the purified acid may be further purified by treatment first with decolorizing carbon and then with alkali-metal permanganate. Examples are given in which (1) the reduction is effected with a magnesium-aluminium alloy and acetic acid; (2) the crude acid is dissolved in xylene and treated with sodium bisulphite solution; acid sodium phthalate may be recovered from the aqueous layer; (3) treatment as in example (2) is followed by treatment with dilute caustic soda solution; (4) the crude acid is melted under an aqueous solution of sodium bisulphite and caustic soda.
