Title: Improvements in or relating to fluid-pressure servo-motors
IPC: F15B11/072
Filed: 1951-11-13
Abstract: 706,366. Pneumatic single stroke apparatus. M.A.F. SOC. CIVILE D'ETUDES POUR MATERIEL DE FONDERIE. Nov. 13, 1951 [Nov. 15, 1950], No. 26546/51. Class 8 (2). [Also in Groups XXII and XXIX] A fluid pressure reciprocating motor, used in particular for opening chilled casting moulds, has a pneumatically actuated member coupled directly to the part to be moved and a hydraulically operated member connected through a lost-motion connection with the pneumatic member, whereby the hydraulic member is used for producing a high power output for part of the operative cycle of the servomotor, in particular for initially separating the moulds and the pneumatic member is used for producing a low power output for a part of said cycle. The motor comprises coaxial cylinders 1, 2 containing pistons 3, 4 respectively actuated by gaseous fluid. The piston 3 is connected to a device to be operated. An annular space 11 containing liquid communicates through a duct 11' with the internal space 7<SP>1</SP> movable in an intermediate cylinder 5<SP>1</SP>. The space 7<SP>1</SP> communicates through ports 12 with an annular space 13. Gaseous fluid under the control of a manually or automatically operated distributer is admitted through a pipe 22 and moves the piston 4 to the right whereupon a plunger portion 10 thereof enters the space 7<SP>1</SP> and pressurises the liquid trapped therein which acts differentially on the piston 7 and moves it to left.. The latter is connected by a rod 8 with the piston 3 which is thus moved simultaneously to commence its power stroke and first uncovers a port 20". The elastic fluid in the cylinder 1 thus acts through a conduit 20 on the right hand side of the piston 3 and assists its movement to the left. Movement of the piston 7 is stopped by its engagement with the left hand end of its cylinder whereupon the piston 3 moves alone to complete the power stroke. During the latter a pipe 23 is open to exhaust. The return stroke is effected by admitting gaseous fluid to the pipe 23 and opening to exhaust the pipe 22. Towards the end of its return stroke the piston 3 engages a head 9 on the rod 8 and returns the piston 7. In another embodiment the admission of gaseous fluid to the cylinder 1 is delayed until the piston 4 has moved a considerable distance in its cylinder and the initial separating movement of the nioulds is effected by liquid-pressure only. The hydraulic piston 7 may be'effective during the whole of the power stroke.

Abstract: 502,118. Tools for grinding glass. PILKINGTON BROS., Ltd., and GRIFFIN, J. H. Oct. 5, 1937, No. 26879. [Class 60] A rotary iron tool for use with sand and water as the abrasive, for grinding the under surface of flat glass comprises a disc 1 on which are fixed or formed iron nogs 2 so that distributing channels 3 are formed passing from the central portion of the tool to the rim 5 with mixing channels 6 connecting the channels 3, the abrasive being supplied through a hole 7 to a central space 4. In order that the tool may wear uniformly, the depth of the channels 3, and if desired the channels 6 is maintained less than the full depth of the nogs by partially filling the channels with a composition, for example, plaster having a gypsum base and Portland cement, which is worn down by the flow of abrasive so as to keep the operative depth of the channels constant as the tool wears down. The depth of the filling may vary at different radii of the tool, for example, as shown in Fig. 3, where progressively shallower fillings 10, 11, 12 are employed ; the composition of the filling also may vary, to give different rates of wear at different radii of the tool.

Abstract: 650,439. Insulated conductors. DU PONT DE NEMOURS & CO., E. I. Oct. 19, 1948, No. 27134. Convention date, Oct. 31, 1947. Drawings to Specification. [Class 36] An electric conductor is insulated by means of a ceramic coating and a superposed sheath composed of polytetrafluoroethylene or a copolymer of tetrafluoroethylene and another polymerisable organic compound containing an ethylenic double bond. A suitable copolymer is the reaction product of 50-85 per cent tetrafluorethylene and 50-15 per cent ethylene. In one method of carrying this out the conductor is first coated electrophoretically with a porous ceramic coating. It is then passed through a wetting bath consisting of a 2 per cent aqueous solution of the sodium salt of the sulphuric acid ester of a mixture of long-chain alcohols (predominantly lauryl alcohol) and through an aqueous suspension of polytetrafluorethylene after which the coated wire is passed through an oven heated to about 750‹ C. The last three steps may be repeated two or three times. In an alternative method the initial coating on the conductor may be obtained from a suspension mixture of ceramic and polytetrafluoroethylene, this coating being heated to coalesce the particles prior to the application of the polymeric sheath, which may also be applied electrophoretically. The first coating of the polymeric material may contain a hydrous oxide. Specifications 614,762, 615,125, 631,570, [all in Group IV (a)], 642,025 and 650,399, [Group IV (a)], are referred to.

Abstract: 747,780. Filters. PUROLATOR PRODUCTS, Inc. Oct. 7, 1953 [Nov. 1, 1952], No. 27530/53. Class 46. A method of manufacturing a filter element including a body and sealing means comprises inserting solid unpolymerized adhesive members between the ends of the body and sealing means and applying heat and pressure to the outer surfaces of the sealing means to press the sealing means and adhesive members against the ends of the body and form a bond between the sealing means and the body by polymerizing the adhesive members. Adhesive supplied in sheet form is cut into rings 15, Fig. 2, to fit the inside flat surfaces of end discs 13. A pleated filter body 11, perforate covering 12, discs 13 and adhesive rings 15 are placed in the relative positions of Fig. 2 and are brought together under heat and pressure. The temperature is such as to achieve polymerization of the rings 15 and their bonding to the end edges of the pleated body 11 and to the inner surfaces of the end discs 13. The temperature permitting the shortest polymerization period is preferred. The discs 13 may be of metal or paper, the adhesive being selected accordingly. In an alternative method unpolymerized liquid adhesive may be discharged in the shape of the ring 15 from a hopper on to a disc 13 on a moving belt (Fig. 3, not shown), the movement of the belt, carrying a series of discs 13, and discharge of adhesive from the hopper being synchronized. The filter element may be of the type disclosed in Specification 692,756, including layers of pleated units 24, 25, Fig. 5, the pleats in adjacent units being at right angles to each other. Solid unpolymerized adhesive inserts 27 are fitted inside a frame 26, the frame is fitted over the assembled units, and heat and pressure to polymerize the insert and to effect bonding are applied. The adhesive may be applied in liquid form to unfolded frames 26 on a moving belt and allowed to solidify on the frames.

The valve is shown in the closed position, the controlled fluid acting on the underside of piston 36 through permanently open passages 98, 100, and on the upper surface of the larger piston 40 through passages 78, 80, 82, 84, 86, past valve 88 which is held open by a biasing spring 77 acting on armature 72, and passages 92, 94. The valve is opened by energizing a solenoid 68 to raise armature 72, close valve 88 and open valve 104 to vent piston 40, the fluid acting on piston 36 lifting plunger 34. Upon de-energizing solenoid 68, or in the event of current failure, spring 77 moves armature 72 downwards to open valve 88 and close valve 104 so that the fluid again acts on piston 40 to close the valve. As shown the undersurface of piston 40 is vented to atmosphere through a passage 109, but in a modification, Fig. 4 (not shown), this surface may be in permanent communication with pressure inlet 18 and the undersurface of piston 36 vented to atmosphere.

A bellows chamber 4 connected to the rod 8 is subject to the pressure of the cooling-water, and holds the rod 8 depressed while the water is flowing, while a diaphragm chamber 9 connected to the rod 14 contains fluid whose pressure rises and falls with the temperature of the cooling-chamber or element, so that the rod 14 is depressed to allow the switch to close the heating circuit when the temperature is above that desired. The switch is open when either rod is raised, irrespective of the position of the other rod. The movement of the rod 14 is used to start and stop the cooling- water supply.
