Title: Improvements in gas meters
IPC: G01F3/30
Filed: 1920-07-08
Abstract: 147,691. Pintsch Akt.-Ges., J. Sept. 20, 1916, [Convention date]. Gas meters.-In a wet gas meter having an oil charge the breast box 1 is divided into compartments 3, 4, the former communicating by channels 5, 6 with the receiving-chamber 7 and the latter with the measuring-chamber 9 communication being established between the compartments 3, 4 by a pipe 8. The apparatus is charged through an inlet pipe 16 the liquid passing to the measuring- chamber 9 through an opening 16<1> thence to the compartment 4 of the breast box through openings 14<1> arranged in the front wall of the drum casing. From the compartment 4 the oil passes to compartment 3 by the pipe 8 and to a sump 15 through a pipe 14 and flows off through an opening 12<1>. The screw 13 is then removed and the oil in the compartment 3 is allowed to flow out of the opening 13' until it is at the level of said opening. On closing the openings 12<1>, 13<1> the meter is ready for use, the overflow pipe 8 main. taining the liquid level in compartment 4 constant by conveying excess oil to compartment 3, and a scoop 11 driven by means of the measuring-drum 10 transfers oil to the measuring-chamber 9 from the receiving-chamber 7 so as to maintain the level of oil therein.

Title: Improvements in or relating to machines adapted for use in setting terminal tags
IPC: H05K13/04
Filed: 1961-06-01
Abstract: 983,104. Orientating terminal tags. GEORGE TUCKER EYELET CO. Ltd. June 1, 1961 [June 2, 1960], No. 19729/61. Heading B8S. Terminal tags for insertion into an insulating board are discharged from rotating hopper 26 (Fig. 1) down shoot 28, are uniformly orientated by rotating disc 54, pass down shoot 32 and are engaged by vertically reciprocating pins 100 and pressed into board B. Orientating device 54, Fig. 3. -A tag T from shoot 28 falls into a slot 76 of disc 54, resting therein in a swinging position. If the tag lodges in the slot with its arm in the downward position the tag is delivered thus orientated into shoot 32. But if the tag lodges in a slot with its arm in the vertical position (an example is shown) then as the disc 54 is stepped round anticlockwise the raised arm of the tag engages corner 74 and the tag swings round so that the arm swings vertically into its downward position. Thus all tags are discharged into shoot 32 uniformly orientated with their arms downwards. Insertion operation, Fig. 7.-Arm 20 reciprocates in the vertical direction to cause a tag to be engaged by the downwardly moving pin 100 to withdraw it from between spring fingers 34 of shoot 32 and to insert it into a board by engagement with anvil 16. The downward movement of bar 20 simultaneously causes shoot 32 containing the tags to be displaced leftwards about pivot 22 by the engagement of roller 94 attached to bar 20 with a cam carried by shoot 32, the displacement of shoot 32 causing fingers 34 to open to free the tag for insertion by pin 100. At the same time the bar carries a pivoted pawl 62 which engages a gear 60 to cause the orientating disc 54 to make one step and to release a tag into the shoot 32.

Title: Apparatus for the disposal of industrial slags
IPC: C21B3/08
Filed: 1943-11-26
Abstract: 572,111. Granulating slag. BJORKMAN, E. B., and ESCOR INDUSTRIES, Ltd. Nov. 26, 1943, Nos. 19794/43 and 465/44. [Class 82 (ii)] [Also in Group V] Slag falling from a blast furnace, cupola, or the like is elevated and carried along an upwardly-directed shoot by a jet of water from apparatus located beneath the slag outlet, the shoot terminating in a downwardly-directed mouth over a draining apparatus or a combined draining and disposal hopper. As shown, the slag falling from the furnace 1 is forced by a jet 3, which may be arched in cross-section along a shoot 4 having a hinged flap at the discharge end to direct the slag into one of two hoppers 6 provided with openings 8 for discharge of surplus water, the hoppers being provided with gates 11 for discharging the slag into wagons 12. The water from the openings 8 passes into a trough 9 connected to a drain pipe 15, to which is also connected a gutter 10, receiving drippings from the shoot 4. Trays 13 are located under the hoppers 6 to receive water escaping through the gates 11, and are arranged to be moved out of the way when the gates are opened, the water being discharged into trough 14, connected to the drain 15. The jet 3 may be adjustable to be directed on to the top or bottom of the shoot to produce granulated or foamed slag. In modifications, the shoot'discharges (a) into a pivoted vessel having perforated sides and divided into two compartments, so that the weight of slag in one compartment causes the vessel to tilt to discharge the contents into a wagon and to bring the other compartment under the shoot ; (b) into compartments in a perforated drum rotating continuously ; or (c) on to a perforated endless conveyer belt.

The vane D works in a sector shaped chamber B and is integral with an arm E which actuates a rocker F reciprocating the cutter. At the rear end of the clipper is a valve chamber H in communication with the atmosphere throughtwo apertures h. The forward face K of the valve chamber contains three ports N, M ; ports N communicate with opposite sides of the vane chamber and port M with the vacuum scource through ports m<1>. Over the three apertures N. M oscillates a hollow rocker which always places the central port into communication with one or the other of the ports N alternately thereby causing atmospheric pressure and a vacuum to operate on opposite sides of the vane. The rocker is actuated by the rocker F through an arm Q passing through rocker F and impinging against F at f <2>at the limits of its movement. A spring controlled roller q in the arm Q oscillating in a slot a<4> engages the valve rocker P.

Title: Improvements relating to the catalytic desulphurisation of hydrocarbons
IPC: C10G45/28
Filed: 1953-07-21
Abstract: In the catalytic desulphurization of hydrocarbons by contact in the presence of hydrogen with a fluorine-containing cobalt molybdate or alumina catalyst at elevated temperature and pressure, involving alternate periods of processing and regeneration of the catalyst to remove carbonaceous deposits, there is added during the processing period a small amount of a fluorine-containing compound so as to maintain the fluorine content and activity of the catalyst at the desired level. Suitable fluorine-containing compounds are dichlorodifluoromethane, tertiary butyl fluoride, and hydrogen fluoride; these may be added to the liquid or vaporized feedstock or to the hydrogen-rich recycle gas, either continuously or only during the early part of the processing period.  A convenient method is to dissolve the compound in a small amount of the feedstock and introduce it into the reactor as required. Examples describe autofining processes.  Specifications 719,627 and 747,663 are referred to.

Abstract: 508,142. Recovery of copper; cuprammonium compounds. BRITISH BEMBERG, Ltd. July 12, 1938, No. 20605. Convention date, Sept. 9, 1937. [Classes 1 (ii) and 1 (iii)] Lime-containing copper mud obtained in working up copper-containing waste waters from the cuprammonium artificial silk industry, for example, by precipitating ammoniacal copper-containing spinning water with lime, is treated with ammonia and an alkali metal or ammonium carbonate, and preferably with ammonium salts such as the sulphate or chloride so that the copper is converted into a tetrammine compound, and calcium carbonate is precipitated, carrying down impurities present. The solution is (1) heated, e.g. at 80-85‹ C. until all the ammonia has escaped, the copper separating as basic salt, e.g. carbonate or sulphate, or (ii) heated with addition of caustic soda, the copper depositing as black oxide which may be worked up to any basic salt. The ammonia is led back to the circuit, in process (ii) partly after conversion into the desired ammonium salt. In process (i), ammonium sulphate solution containirig a relatively small amount of copper separated from the basic salt is also introduced into the circulating process. The mud may previously be treated with a deficiency of acid to form a basic salt, for example with the so-called copper acid arising on decoppering freshly produced structures with dilute sulphuric acid,
