Abstract: 1,136,468. Valves. CONTROLS CO. OF AMERICA. 22 May, 1967 [22 July, 1966], No. 23603/67. Heading F2V. Diaphragm 48 of a gas pressure regulator carries a closure member 24 which restricts flow between inlet 20 and outlet 22 in accordance with the pressure beneath the diaphragm, and one or both of a pair of loading springs 46, 52 can be rendered inoperative selectively to make the regulator suitable for use with either town or natural gas and to render the whole regulator inoperative when it is fed with gas from a regulated supply. A spring loaded rod 60 carries a spade 62 which is selectively engageable with each of a pair of lips x, y on a member 54 so that either both springs are operative (as shown) or the end of rod 60 engages slidable seat 50 (as in Fig. 2, not shown) to render spring 52 inoperative. With the rod in this position member 54 can be screwed down into sleeve 34 to cause seat 50 to abut against diaphragm projection 74 (as in Fig. 3, not shown) so that the whole regulator becomes inoperative. With the parts in the position shown in Fig. 1 adjustment of loading springs 46, 52 is effected by a screw 44 the head 42 of which engages lip 38 on sleeve 34. In a modification (Fig. 2, not shown) this lip is also engaged by a thermally actuated lever.

Abstract: 1391091 Ethylene dichloride ALLIED CHEMICAL CORP 19 May 1972 [20 May 1971] 23743/72 Heading C2C A process for the continuous production of ethylene dichloride by reaction of ethylene and chlorine in a liquid ethylene dichloride reaction medium, comprises: (a) continuously introducing ethylene and chlorine, in relative proportions such that the amount of ethylene is at least the stoichiometric amount required to produce ethylene dichloride, into a vertically disposed reaction zone containing the reaction medium, the points of introduction of ethylene and chlorine being at or near the bottom of the reaction zone, and maintaining the temperature in the reaction zone at the boiling point of the reaction mixture to effect an exothermic reaction between the ethylene and the chlorine and to induce upward movement of the liquid reaction medium in the reaction zone, (b) conducting the upwardly flowing liquid from a point at or near the top of the reaction zone to a point at or near the top of an externally cooled vertically disposed heat extraction zone to cool the liquid by heat exchange and to cause it to flow down the heat extraction zone, (c) conducting the cooled liquid from a point at or near the bottom of the heat extraction zone to a point at or near the bottom of the reaction zone such that a continuous circulation of the liquid between the reaction zone and the heat extraction zone is maintained without mechanical means, and (d) removing from the reaction zone ethylene dichloride-containing vapours formed by the heat of reaction of the ethylene and chlorine, and recovering ethylene dichloride from the vapours by condensation. The ethylene dichloride-containing vapours are preferably fractionally distilled to remove lower boiling impurities before the ethylene dichloride is separated from the vapours in step (d). Ferric chloride may be added to depress the rate of substitution reactions, and the condensed ethylene dichloride product may be passed through a packed column countercurrent to ethylene to remove hydrogen chloride impurity from the ethylene dichloride. The ethylene dichloride product may be pyrolysed to vinyl chloride. A suitable apparatus for carrying out the process according to the invention forms the subject matter of Specification 1,391,092.

Title: Improvements in bright annealing of alloys of the type containing a constituent volatile at the annealing temperature
IPC: C22F1/02
Filed: 1938-08-16
Abstract: 518,132. Annealing. GENERAL ELECTRIC CO., Ltd., JENKINS, I., and WILLIAMS, S. V. Aug. 16, 1938, No. 24115. [Class 72] In the bright annealing of an alloy, such as brass, which contains a constituent volatile at the highest temperature attained during annealing without substantial change in its composition, the alloy is first heated in vacuo up. to a temperature below the highest temperature and is then heated up to the highest temperature in an atmosphere of non- oxidising gas, such as a mixture of nitrogen and hydrogen produced by cracking ammonia. In an example, rolled brass strip is enclosed in a sealed annealing pot provided with an outlet to a pump. Pressure in the pot is reduced to about 5 mm Hg. and the pot heated to 500‹C. When this temperature is reached, the pot is filled with a mixture of nitrogen and hydrogen and maintained at a temperature of 550- 600‹C. for 15-30 minutes and then cooled while still filled with gas.

Abstract: 722,160. Holding tools. E.M.B. CO., Ltd. Sept. 8, 1953 [Sept. 26, 1952]. No. 24149/52. Class 61.  A hand tool of the pliers type in which the jaws are operated by air pressure comprises a hollow cylindrical body a having therein a slidable, spring loaded piston b, a pair of jaws d pivoted to the end of the body, a wedge i extending from the. piston and adapted to impart a closing movement to the jaws, and a hand operable air control valve on the body. As shown air is applied through a flexible pipe to an inlet passage p and through a valve to a passage q leading to the cylinder. The valve includes a spring loaded closure member m made from rubber or the like which cooperates with a seating n in the body. Co-axially with the member m is arranged a hollow spring loaded, slidable stem r which is operable by a short lever t. In closed position of the valve the stem is open to the outer atmosphere by way of one or more radial ports u. Movement inwards of the lever causes the stem r to bear on the closure m and move the latter off its seating n. In a modification the tool is operated by suction.

Abstract: 1343316 Conveyers JEUMONT-SCHNEIDER 19 April 1971 [17 March 1970] 24211/71  Heading B7L [Also in Division H2] A conveyer system comprises a track in the form of two opposed U-section members P 1 , P 2  and electromagnetically propelled carriages, as 2, the track having armatures I 1 , I 2  on the sides thereof at level sections of the track and auxiliary linear motor inductors R 1 , R 2  at the sides on inclined sections of the track, and each carriage 2 having a pair of back-to-back two state members M 1 , M 2  thereon which can be switched between one state wherein they act as linear motor inductors with the armatures I 1 , I 2  and a second state wherein they act as auxiliary armatures in association with the inductors R 1 , R 2 , the arrangement providing more power when the carriages are climbing an inclined track section. The armatures I 1 , I 2  are in the form of copper or aluminium plates and the inductors R 1  R 2 , which form part of a three-phase linear motor are fed with threephase current by cables U 1 , U 2 . Where the track changes from the level to an inclined section there is a gap between the armatures I 1 , I 2  and inductors R 1 , R 2  equal to the length of one carriage 2. Alternatively the armatures and inductors may be staggered on one side of the track relative to the other so that drive is maintained to. the carriages at all parts of the track. In level track sections the two state members M 1 , M 2  act as moving inductors collecting their supply from supply conductors through brushes, B 1 , B 2 , and when the carriage is in an inclined section of track the members M 1 , M 2  act as moving armatures being connected by the brushes B 1 , B 2  to variable threephase impedances Z. If desired armatures I and indicator R may be provided on one side of the track only and as a further alternative at level track sections the armatures may be connected to a common system of variable impedances and the members M 1 , M 2  be connected in parallel to the same supply, whereby the linear driving motors act as synchronous motors and the carriages are constrained to travel at the same speed regardless of load.
