Abstract: 1,263,058. Fluid-pressure servomotor system NATIONAL VULCAN ENG INSURANCE GROUP Ltd. Feb.21, 1969 [Feb.23, 1968], No.8822/68. Heading G3P. A valve arrangement for a fluid-pressure system e.g. a steam boiler, comprises a safety valve 6 having a major loading 11, and a pilot valve 16 adapted to divert pressure fluid from the system and apply it as a servo-loading to the safety valve 6 to augment the major loading 11, the pilot valve 16 being operable at a predetermined fluid-pressure P in the system by pressure fluid from the system to remove the servo-loading from the safety valve. The fluid diverting means 16, on return of the fluid-pressure P, being adapted to reapply the fluid servo-loading at the chamber 14. The pilot valve 16 is preferably a shuttle valve 17 that is loaded by a spring 18. In its raised position, fluid in the pipe 15 is vented to the atmosphere (arrow E), so that the main blow-off valve 6 opens. The response of the shuttle valve 16 may be improved by incorporating an electro-mechanical pressure switch responsive to boiler pressure and solenoid attachment (not shown).

Abstract: 1533618 Seaming non-metallic sheet material BIELOMATIK LEUZE & CO 5 March 1976 [8 March 1975] 08824/76 Heading B5K Apparatus for welding a cover 23 to a container 24 comprises a device 16 for pressing the cover 23 on to the container 24 to effect welding after heating of the parts to be welded and a pressure connector 33 connectible to at least an opening 29 in the cover 23 and leading to pressure responsive means for testing the container for leaks under pressure. In the embodiment shown, the container and the cover form an electrical battery, e.g. a lead accumulator, casing and each comprise transverse walls 28 separating individual cells. For each cell, the cover 23 has a filling opening 29 and an opening 30 for an electrical terminal pin. An edge 22 on the cover 23 extends lower than a side wall portion 27 to be welded at 26 to the container 24. The device 16 has a pressure shoulder 18 surrounded by a guide spigot 19 and has pivoted thereto levers 20 with fingers 21 to engage under the edge 22. The levers 20 are displaceable by bars 25 actuated by a fluid cylinder (not shown). The device 16 is movable vertically by a pneumatic cylinder 32. The connector 33 has a carrier 34 displaceable vertically on guides 35 by a fluid cylinder 36. Connection heads 37, one for each opening 29, are guided in the carrier 34 and are urged downwardly by springs 38 so that seals 39 thereon seal the openings 29. Flexible tubes 41 connect passages 40 in the heads 37 to a testing device 42 having meters 43 and a pressure medium feed pipe 44. The openings 30 are closed by seals 47 on members 45 urged downwardly by springs 46. In operation, a container 24 is fed on a roller table 13 to the welding position and a cover 23 is gripped between the shoulder 18 and the fingers 21 with the connector 33 held raised. The device 16 is raised and a welding tool 48 moved between the cover and container to plasticize the edges to be welded by contact or radiation heating. The tool 48 is retracted and the device 16 is lowered so that the shoulder 18 presses the cover on to the container to effect welding. After welding, the connector 33 is lowered so that the seals 39, 47 seal the interior of the container to which pressurized fluid is then supplied. After this supply is switched off, the meters 43 monitor the pressure in each cell to ascertain whether there is any inadmissible drop in fluid pressure. In modifications (not shown), (a) the connector (33) is not independently movable by the cylinder (36); (b) the heads (37) and members (45) are actuated independently of one another; (c) plug-shape seals are used instead of annular seals (39); and (d) the device (16) is guided on the connector (33) so that the pressure is relieved after welding before the pressurizing operation.

Title: Improvements in or relating to circular independent needle knitting machines
IPC: D04B9/10
Filed: 1947-04-03
Abstract: 625,991. Knitting-machines. HEMPHILL CO. April 3, 1947, No. 9140. Convention date, April 9, 1946. [Class 74 (ii)] The wrap horn of a superposed cylinder independent needle machine is raised to an inoperative position and lowered to an operative position by mechanism moving the wrap head to its inoperative and operative position. The movement of the wrap horn is such that it is moved into its operative position before the wrap head reaches its operative position and is moved from its operative position only after the wrap head has been moved from its operative position. As described, the wrap head spindle is mounted to be moved to an inoperative position, substantially concentrically with the needle cylinders, and to an operative position, eccentrically of the needle cylinders, by a plate 18 as is described in Specification 613,838. The plate 18 carries an extension 21 on which is mounted a roller 22 which supports the side of plate 18 by running on a track 23. A pin 27, projecting from the extension 21, is adapted to engage one end 16 of a pivoted lever 14 bearing with its other end against the underside of a plate 7 that is attached to a plate 6 connected to the spindle 5 supporting the wrap horn 4. Plate 7 is mounted on top of a shaft 8 which is slidable in a sleeve 9 and is urged towards its lowermost position by a spring 10. Consequently, upon movement of the plate 18 to move the wrap spindle to its operative position eccentrically of the needle cylinders, the pin 27 moves away from the lever 14 to permit the spring 10 to lower the wrap horn, the wrap horn being in position before the wrap spindle reaches its operative position. Similarly, when the wrap spindle is taken out of its operative position, the wrap horn will remain in position until the pin 27 engages the lever 14, whereupon the wrap horn is raised to its inoperative position. Specification 624,182 also is referred to.

The piston 42 of the fluid relay, Fig. 3, is connected to a lever 45 which tilts blades 70, 71 in opposite directions, or brings them into a horizontal position, and is operated by fluidpressure controlled by a valve 30 held normally in the central position by springs 63, 63<a> or a weight and operated by the cylinder 26 of a dashpot, the. ends of which are connected by a passage containing a regulating-valve 28<1>. The piston 25 of the dashpot is controlled by the pendulum 11 through a subsidiary relay. When the piston 25 moves slowly, the movable cylinder 26 is unaffected; when the piston is moved faster, the spring 63 or 63a yields and the valve 30 is moved; sudden movements of the piston 25 are permitted by spring-valves 25a, 25<b>. The subsidiary relay comprises a differential piston constantly subjected to oil-pressure on the right. The discharge of oil through the passages 21, 23 is controlled by a. needle valve 17 moved by the pendulum. The secondary controlling-valve 53 is connected to the pendulum as shown, and serves to retain the piston 42 in either of its end positions, or to return it to the central position when the pendulum returns to rest in the vertical position.

Title: Improvements in the manufacture of polyamide powders
IPC: C08J3/14
Filed: 1950-04-14
Abstract: Fine powders of linear straight-chain polyamides, obtained by polycondensation of an amino acid or a diamine and a dibasic acid, are prepared by dissolving the polyamide with the aid of heat in a solvent chosen from aliphatic, aryl aliphatic and hydroaromatic alcohols, aryl aliphatic and hydroaromatic ketones, and lower aliphatic acids, cooling the solution and separating the finely-divided particles thus formed.  The dissolving of the polyamide may be effected at normal or superatmospheric pressure, and the separation may be effected by distilling off the solvent at a temperature at which the polyamide is practically insoluble in the solvent, or by centrifuging or draining off the solvent, usually with subsequent evaporation of absorbed solvent.  Where the solvent used distils at a high temperature, the solvent remaining in the mass of particles obtained by draining may be replaced by a lower boiling solvent.  Any agglomerates that form may be broken down by slight grinding.  Solvents specified are: methyl-, ethyl-, isopropyl-, butyl-, isobutyl-, amyl-, heptyl-, cyclohexyl-, benzyl-, and phenylethylalcohols; acetophenone and cyclohexanone; formic and acetic acids.  Polyamides specified are: polyundecanamide (from 11-amino-undecanoic acid), polydecanamide (from 10-aminodecanoic acid) and polyhexamethylene adipamide.  Coloured polyamide powders may be obtained either by dissolving a previously-dyed polyamide or by dispersing a dyestuff in the solvent.
