IPC: H01M12/06
Filed: 1970-06-22
Abstract: 1276953 Gas-depolarized electrochemical cell M N YARDNEY 22 June 1970 [30 June 1969] 30101/70 Heading H1B In a gas-depolarized cell the anode(s) is/are removably supported on the cathode for joint removal together with a detachable housing part, such as a lid, from the rest of the cell housing to facilitate refuelling of the cell. In an embodiment, two plate-shaped anodes 19a, 19b joined by flexible conductive strap 20 flank a flattened tubular cathode 15 which has a ledge 14 for supporting the anodes. A detachable lid 22 fits over the top of casing 10 when the cell is assembled and seals in flange 16 of the cathode and packing strip 17, and is held against the casing by clips 32. The case is provided with legs so that during operation depolarizing ambient air enters the lower end of the chimneylike cathode and exits at the upper end through slot 28 in lid 22. When the anodes are spent, the lid can be lifted thereby extracting cathode 15 with the spent anodes 19a, 19b on ledge 14, and the anodes can be replaced. A perforate charging electrode of inert conductive material can be interposed between the cathode and anode(s).

Title: Method and device for starting and stopping a liquid-liquid extraction process in an apparatus
IPC: B01D11/04
Filed: 1972-06-28
Abstract: 1395605 Mixer/settler apparatus KEMIRA OY 28 June 1972 [10 Dec 1971] 30362/72 Heading B1F In a countercurrent mixer/settler liquid/ liquid extraction process, if for some reason a mixer 1 has to be stopped, the formation of a false emulsion in a mixing chamber on restarting the mixer is effected by closing valve 6 when mixer 1 is stopped and allowing the phases to separate, and then opening valve 6 carefully to allow all of the heavy phase to flow back through pipe 5 to auxiliary space 11. Before the mixer 1 is to be restarted, valve 6 is closed, and after mixer 1 has been restarted, valve 6 is opened slowly so that heavy phase flows slowly back into the mixer chamber which eliminates the formation of a false dispersion.

Filed: 1926-12-01
Abstract: 284,057. Paulin, W. J., Kennedy, J. Y. M., and Fortune, T. C. Dec. 1, 1026. Bulkhead doors are retained open by a spring catch comprising a snug 9 on the door, the nose of which is formed with an easy tapered surface 10<a> to enable it to displace readily and engage behind a spring-controlled keep plate S mounted on the bulkhead and also with an abruptly bevelled surface 10<b> which engages with a complementary surface 8<a> on the keep member. The keep plate is controlled by spiral springs 12 the tension of which is adjusted by nuts 13. In the case of a horizontally sliding door, the device will prevent the door from closing under rolling of the vessel. In the case of a. vertically sliding door the device will keep the door raised until the normal supporting pressure falls to a predetermined amount, or the engagement between the members of the fastening may be such as to keep the door raised even if the sustaining pressure wholly fails.

Title: Improvements in or relating to steam traps
Inventor: MARX FRANK RALPH
IPC: F16T1/08
Filed: 1963-08-02
Abstract: 987,344. Valves. SPIRAX-SARCO Ltd. Oct. 30, 1963 [Aug. 2, 1963], No. 30831/63. Heading F2V. [Also in Divisions F4 and G1] In a steam trap for controlling the escape of condensate from a chamber 2 the valve 9 is subjected, in the closing direction to a force applied by a pile of bi-metallic elements 11 each of which in plan view presents a number of projecting parts separated by re-entrant angles so that with increasing temperature within the chamber more of said parts of each element become effective to apply a closing force on the valve. In the form shown in Fig. 2 the elements which are serially assembled in opposed pairs on the valve stem 8 and are prevented from rotating thereon, are of cruciform shape, the arms 13, 15 being longer than the arms 14, 16. In operation steam contacting the elements after condensate has been discharged causes each pair to bow apart, first with only the ends of the arms 13, 15 in contact but, as the temperature increases and further bowing occurs, with the ends of the shorter arms in contact to increase the closing force on the valve to overcome the increasing steam pressure thereon. In modifications the elements may have three or more pairs of arms of increasing length. In a further modification the pile of elements is replaced by an element 11B, Fig. 4, of rectangular form having four arcuate section sides 33 . . . 36 joined at the corners at their central parts. The sides 34, 36 are of the same length and height, as are the sides 33, 35, the former being shorter and taller than the latter. As the element is heated the sides become flatter, the initial closing force exerted by the taller sides being augmented as the temperature increases by the shorter sides, the upper edges of which come into contact with a plate bearing on the element and carrying the valve stem.

Catalysts specified are dialkyl and diacyl peroxides, hydrogen peroxide, alkyl and aryl hydroperoxides, azodiisobutyronitrile and redox systems based on persulphates and sulphur compounds of low oxidation stages. As a complex former for heavy metals there is specified ethylene diamine tetraacetic acid.

Water-soluble polyvalent metal salts specified are the chlorides, sulphates and nitrates of calcium, magnesium, alum and zinc and potash alum.  The various components of the polymerization system may be added gradually during the course of the reaction.

Title: Electromechanical transducer
IPC: H04R11/00
Filed: 1964-08-04
Abstract: 1,079,044. Electro-mechanical transducers. INDUSTRIAL RESEARCH PRODUCTS Inc. Aug. 4, 1964 [July 29, 1963; March 17, 1964], No. 31052/64. Heading H4J. A moving armature of a transducer has one part fixed with respect to the transducer frame or case, a coil surrounding a movable part of the armature, and elastomeric or flexible material positioned between and in physical contact with a movable part of the armature and an adjacent surface fixed with respect to the frame or case. A transducer such as described in Specification 959,784 has an E-shaped armature the outside arms 28, 30 of which are clamped in a magnet stack 26. The inner arm 32 is vibratable and is connected by a pin 36 to a diaphragm 38. A cup 22, cover 40 and bulkhead 24 are fluxconductive. Arm 32 passes through a tunnel in a coil 41. The armature has a node along line 18, 16, 14. At higher frequencies an undesirable node would develop near dotted line 21 but by holding the armature at line 18, 16, 14 the undesirable node does not develop. The cup 22 has an opening 42 in which is mounted a slotted bolt 10, the slot of which contains elastomeric material. In assembly, a tool is first inserted through the opening 42 and the armature is grasped and twisted so as to raise or lower the arm 32 in the working gap 34 while testing to ensure zero flux flow in each direction when the armature is at rest. The bolt 10 has its slot filled with flowable elastomer and, after insertion in the opening 42, is adhered or welded to the cup 22. The elastomer may be colloidal rubber. In place of elastomer a plasticized epoxy resin or plasticized cellulose nitrate may be used. Two slotted bolts 10, 12 may be used. The inner walls of the bolt slot may be tapered (Fig. 4, not shown). Elastomer (64), Figs. 7, 8 (not shown), may be introduced by a tube (43) between at least one face of the arm (32) and the end of the coil tunnel remote from the working gap 34. The elastomer (64) is adjacent a node. Alternatively, brackets (28), Fig. 7, attached to the cup (22) may retain elastomer (27) inserted through the opening. In a U- shaped armature, Fig. 10 (not shown), held at a fixed gap (80) and having an adjacent working gap (82) the armature is held along a line (84). An armature of U-cross-section, Fig. 12 (not shown), has magnets or polepieces (90), (92) held in fixed relationship, as is an arm (94). An undesirable node may develop near the drive pin (101) and this is suppressed by holding the armature at a line (96). An E-shaped armature, Fig. 11 (not shown), has a centre arm (102) free to vibrate while upper and lower arms are held fixed. An undesirable node adjacent the drive pin (106) is restrained by holding the centre arm by a member (110). A transducer has the base member (118), Fig. 2 (not shown), of the armature at right-angles to the remainder of the armature.
