Filed: 1975-02-14
Abstract: 1533853 Molten alkali-metal-molten halide cell CHLORIDE GROUP Ltd 13 Feb 1976 [14 Feb 1975] 6387/75 Heading H1B An electric cell has an alkali metal as the reactant at the negative electrode, and a cationically conductive separator physically separating the alkali metal from a reactant at the positive electrode whilst permitting passage of alkali metal cations, the reactant at the positive electrode comprising in the fully charged state a mixture of 33-50 mole per cent AlCl 3  and 50-33 mole per cent FeCl 3  the balance being the chloride of the said alkali metal. The cell may be arranged thus: an outer steel cylinder contains the molten alkali metal, and is the negative current collector; the separator, of beta-alumina, co-axial with and inside the alkali metal, contains the halide reactant and a central graphite rod which is the positive current collector; alternatively the positions of the alkali metal and halide mixture may be reversed. The halide mixture should have Mpt#350 C. and preferably 100-250 C.; the cell is operated, e.g. at 150-250 C.; the alkali metal may be Na, Li, or K.

Abstract: 1,090,034. Deflashing resilient articles. PANGBORN CORPORATION. Feb. 15, 1965 [Feb. 24, 1964], No. 6424/65. Heading B3D. Apparatus for deflashing moulded resilient pieces by abrasive blasting the differentially frozen pieces while they are supported and turned has first and second freezing medium applicators adjacent the means for supporting and turning the pieces. Apparatus generally similar to that in Specification 1,048,477 has nozzles 45 supplied with liquid CO 2  through a header 47 and nozzles 200 supplied with liquid nitrogen through a header 202. Feed through the header 202 is controlled by a solenoid injection valve 208. A stand pipe 206 has a liquid level control 210 controlling a solenoid relief valve 212. In operation, the CO 2  and nitrogen are applied simultaneously. The low temperature, produced by the liquid CO 2  reduces the tendency of the liquid nitrogen to vaporize immediately on leaving the nozzles; the liquid nitrogen sub-cools the CO 2  snow.

Title: Improvements relating to coin-controlled gas meters
IPC: G07F15/00
Filed: 1934-02-28
Abstract: 429,643. Prepayment mechanism for gas meters. ALLGEMEINE ELEKTRICITATS-GES., 2, Friedrich Karl-Ufer, Berlin. Feb. 28, 1934, No. 6522. Convention date, March 25, 1933. [Class 27] Coin-slit closing-devices.-In a prepayment gas meter, a bend 17 in a lever 7 pivoted at 8 enters a slot 9<1> in the coin-shoot 9 and obstructs the coin-slit when the maximum permissible number of coins has been inserted and also when the quantity mechanism has reached its zero position due to the consumption of gas. The lever 7 is controlled by a disc 6 on the shaft 5 to which is fixed the planet-wheel carrier arm 21 of the epicyclic quantity mechanism 1, 2, 3 controlling the gas valve. The disc 6 has a recess 61 in its circumference into which an arm 7<1> of the lever 7 can pass, and also a pin 62 which coacts with the end 31 of the bent arm 17. When the carrier 2<1> is at zero position as indicated by a pointer 4 and the gas valve is closed, the arm 7<1> drops into one end of the recess 61 and the arm 17 closes the coin-slit. To obtain a further supply, a lever 11 is actuated by a knob 10 to swing the lever 7 out of obstructing position, and a coin inserted. This moves the disc 6 so that the arm 71 travels on its periphery and the slot is maintained open for the insertion of further coins. When the maximum number of coins are inserted, the disc 6 is rotated so far that the arm 7<1> drops into the other end of the recess. The pin 62 now bears against the end 31 and prevents the lever 7 from being swung out of the coin-slit, so that further coins cannot be inserted until an appropriate quantity of gas has been consumed and the pin 62 moved away from the end 31.

Different classes of bakery-products may require different treatment temperatures, but the critical temperature will be of the order of 250-300 DEG  F.  A suitable oven in which to treat the products is described in Specification 462,389.  The goods are preferably supported so that their whole surface is exposed to the air stream, e.g. on wire trays or shelves.

Title: Production of acid amides and salts
IPC: C07C231/06
Filed: 1926-03-13
Abstract: 271,969. Synthetic Ammonia & Nitrates, Ltd., Smith, P. A., and Smith, H. G. March 13, 1926. Amides of fatty acids; acetamide; salts of fatty acids; acetates.-Amides of fatty acids are obtained by reaction between an alcohol, preferably in the form of vapour, and hydrocyanic acid, or a substance or substances giving rise thereto, in presence of a dehydrating catalyst at an elevated temperature. A temperature of 250-300‹ C. is suitable when treating methanol, and the catalyst may be alumina or thoria; the reaction may be performed under pressure. The hydrocyanic acid may be prepared by passing carbon monoxide, or gases containing it, and ammonia over a dehydrating catalyst, such as alumina or thoria, at a temperature of 500-600‹ C., the hydrocyanic acid being removed from the products by cooling or by absorption in water or in the alcohol to be treated. The amides may be hydrolyzed with alkali to yield fatty acid salts and ammonia, which may be used again in the process.

Abstract: 512,615. Steam superheaters. MARINE & LOCOMOTIVE SUPERHEATERS, Ltd., (formerly SUPERHEATER CO., Ltd.) and MELHUISH, H. March 7, 1938, No. 7065. [Class 123 (iii)] Steam superheater elements for use in multitubular boilers and particularly in the combustion or return chambers of such boilers comprise two or more intertwined coils 3, 4 and with a longitudinal tube portion 5, 6, in series with it and welded to turns of the coil to constitute supporting and spacing means, the coils having a single inlet and outlet tubes 8, 10, for connection to the respective headers 1, 2. The longitudinal tubes may be united to one header connection steam then flowing in the same direction through the coils, or, in the case of two coils, each header connection communicates with one coil and one tube portion steam then flowing in opposite directions through the coils. The elements, which may be self draining are supported by means of a hook 19, sling or bar engaging with an integral loop 18 at the top of the element. Arrangements in which the headers are disposed above the elements employ the legs 8, 10, as suspending members, nuts adjustable on threaded collars bearing, for example, on plates supported on the roof of an external combustion chamber. In another embodiment the legs 8, 10 extend through hollow stay tubes between an internal combustion chamber and the rear wall. The elements may be arranged behind or in front of water circulating tubes in external chambers. The coils may be circular, elliptical, or of hourglass shape in plan with spaced or coincident axes; when the coils are eccentrically disposed the tubes 5, 6 preferably lie in the angles of intersection of the convolutions and are added to both coils. In a concentric arrangement superposed convolutions may be closely spaced in the lower or gas inlet end of the coils and more widely spaced at the upper end, or selected convolutions may be of hour-glass shape to provide for the escape of gases.

Abstract: 861,267. Automatic material feed-control systems. SCHENCK MASCHINENFABRIK G.m.b.H., C. March 2, 1959, No. 7226/59. Class 38 (4). The rate of feed of loose material from a weigh belt feeder is maintained constant by continuous control of the speed of the belt in dependence on deflections due to the weight of the material on the belt, the rate of feed of the material to the weigh belt feeder being varied simultaneously with the speed of the belt. In Fig. 1 loose material is supplied from a belt feeder 12 to a weigh belt feeder 2. A weigh beam 7, deflected in dependence on the weight of material on feeder 2, operates a potentiometer 15 connected to a tachometer generator 14, driven by feeder 2, so that a voltage is produced representative of the rate of feed of material by feeder 2. This voltage controls a servomotor 18 adjusting a variable-speed drive 13 between an electric motor 19 and feeder 2 so that the rate of feed from feeder 2 is automatically maintained at a value determined by the setting of a potentiometer 20. Feeder 12 is also driven from variable-speed drive 13 so that the material is always supplied to feeder 2 at a rate corresponding to the rate of delivery of feeder 2. In a modification (not shown), potentiometer 15 controls the speed of an electric motor driving feeder 2 and a second potentiometer ganged to potentiometer 15 controls the energization of a vibratory feeder supplying feeder 2. In this arrangement variable resistors are provided to match the characteristics of the motor and vibrator.
