Title: Resilient mountings
IPC: F16F1/42
Filed: 1945-09-17
Abstract: 603,459. Resilient mountings. LORD MANUFACTURING CO. Sept. 17, 1945, No. 23990. Convention date, Sept. 1, 1944. [Class 108 (iii)] A rubber mounting in the form of a laterallyextending rubber arm which is free to deflect in shear comprises a web 2, Fig. 2, extending between end portions 4 provided with verticallyextending openings in which are fixed members 6 for transferring load to and from the arm through surface contact and the contracting gripping action of the rubber on the members 6. Alternatively, the arm comprises one or more webs and an end portion which is of greater thickness than the web or each web and carries the load-supporting member 6. The mounting shown in Fig. 2 is of I-shape in cross-section with the web 2 enlarged at both ends 4 and provided with a vertical opening for receiving a hollow pin 6, the rubber being stretched to receive the pin. In use, the mounting is carried at one end from a support 7, Fig. 5, by a bolt 8 which passes through the hollow pin 6 at one end, and a member 9 is supported from the other end of the mounting by a bolt 11 passing through the corresponding pin 6. If desired, two mountings may co-operate as shown in Fig. 5 to carry the member 9. Instead of providing the hollow pins 6, the securing bolts may be directly gripped by the rubber. To lessen the tendency of the rubber to pull away from the pin 6 under severe deflection, a triangular opening 12 may be provided in the mounting as shown in Fig. 2. In the modification shown in Fig. 2, the mounting is provided with two arcuate webs which branch from opposite sides of the thickened end portion. The mounting shown in Fig. 7 is provided with studs 15 having enlarged heads 14 which are forced into vertical sockets 16 in the mounting, the heads being shorter than the depth of the sockets so that the rubber at the mouths of the latter extends over shoulders on the heads and holds the studs against axial displacement; the arm, in this case, is also provided with enlarged ends. For severe duty, the pins 6 may be bonded to the rubber by rubber cement or vulcanization.

Abstract: 1,087,183. Stapling machines. U. MONACELLI. June 8, 1965 [June 10, 1964; March 17, 1965],No. 24302/65. Heading B4C. A pneumatic stapling machine comprises a staple driving piston 9 slidable in a cylinder 10 under the control of a differential valve piston 15 adapted to normally close the open top of the cylinder, a differential valve member 51, 52, 53 being mounted in the valve piston and arranged to open or close exhaust ports 21, 22, 27 communicating with the top of the cylinder. The differential piston 15 is formed with discs 16, 17 having in their periphery sealing rings 58, 59, Fig. 4, for engagement with tapering seats 56, 57, the ports 21, 22 leading into a chamber 23 between the discs; a resilient ring 18<SP>1</SP> is mounted on the differential piston for engagement with the open top of the cylinder 10. A trigger-operated valve 28<SP>1</SP>, 29 controls the flow of compressed air from a reservoir 3 to the differential piston. In operation, air normally acts, via ports 30, 31 in the trigger valve, on the piston 15 to maintain it in the position shown. Upon operation of the trigger valve, the ports 30, 31 are closed and the differential piston is raised via air acting on the disc 17 so as to permit the air to drive the piston 9 on its working stroke; the air in front of the driving piston is forced through a slot 41 into a chamber 42. When the trigger valve is released at the end of the working stroke, the differential piston is urged downwardly to seal the top of the cylinder and the valve 5, 52 is opened so that the piston 9 is moved upwardly by the compressed air trapped in the chamber 42.

Abstract: 1,105,285. Treating and thereafter heatsealing polyolefine fibres. KALLE A.G. 11 June, 1965 [11 June, 1964], No. 24786/65. Headings B5B and B5K. Biaxially stretched polyolefine film is exposed to an electric discharge of the corona or glow type in the presence of a halogen or a halogencontaining gas and the film so treated is heatsealed, i.e. autogenously welded, within 10 days after the treatment. The sealing temperature may be 120‹ to 130‹ C. The film may consist of isotactic polypropylene, or of a copolymer of a major proportion by weight of isotactic polypropylene and a minor proportion of another polymer, or of polyethylene. The film may be treated by passing the film over and in contact with an earthed metal roller which has a layer of insulation in its peripheral surface. Above the roller parallel to the axis of the roller- and spaced a short distance therefrom are located electrodes consisting, for example, of wire netting, or of narrow metal bars or wires spaced apart from one another and parallel with the axis of rotation of the roller. The electrode discharge may be provided by a generator providing a current of 5 to 10 kilocycles per second frequency giving an electrode potential of about 8 kilovolts and an output of 2 to 4 kilovoltamperes. The electrodes may then be spaced about 0.5 to 2 mm. from the surface of the film. The roller may be surmounted by an inverted box of electrically non- conducting material, the opening of which is bounded by the roller, the gap between the edges of the opening and the roller being provided with strips of flexible sealing material, such as polytetrafluoroethylene. The box is provided with one or more inlets through which chlorine, a mixture of chlorine and another gas or a mixture of bromine vapour and a gas such as nitrogen is introduced. Example 2 discloses the use of corrugated heat sealing jaws.

Abstract: 1,043,211. Anaesthetic apparatus. VSESOJUZNY NAUCHNO-ISSLEDOVATELSKY INSTITUTE MEDITSYNSKIKH INSTRUMENTOV I OBORUDOVANIYA. June 21,1963,No.24855/63. Heading AST. Anaesthetic apparatus provided with oxygen and narcotic gas cylinders includes an equalizing pressure valve 9 which reduces or cuts off the flow of one gas when the other gas is reduced or cut off respectively. The valve 9 comprises a concertina tube 16 the interior of which communicates through a valve 13 with a nitrous oxide cylinder, the tube being located in a chamber communicating with the oxygen cylinder through a valve 14. The valves 13, 14 have a common stem 15 secured to the concertina tube so that in the event of failure, shut off by the valve 12, or reduction in pressure of the oxygen supply, the concertina expands to cause closure or partial closure respectively, of the valve 13 controlling the nitrous oxide supply. Similarly, if the nitrous oxide supply should fail, the concertina contracts to cause closure of the valve 14 controlling the oxygen supply. During normal operation of the device, oxygen and nitrous oxide are supplied to manifolds M, M<SP>1</SP> respectively, communicating through a selected one of several valves 10 with a duct D which receives a mixture of the two gases in a proportion determined by the valve 10 selected. Each valve 10 has metering orifices 11, 11<SP>1</SP> communicating with the manifolds M, M<SP>1</SP> respectively, and is opened by pressing an appropriate knob 10<SP>1</SP>(Fig. 3) against a spring. Oxygen alone may be supplied to the duct D through a valve 23. The valves 10 and the valve 23 are mechanically interconnected so that opening of one valve 10 causes closure of the previously opened valve. Gas passes from the duct D via an optionally open anaesthetic evaporator 6 to a chamber 29 which communicates with a bellows 28. When the bellows is full, its cover plate 30 moves to close the oxygen supply valve 12, thus causing shut off of both the oxygen and nitrous oxide. A diaphragm 35 (Figs. 8 to 10, not shown), forming one side of the chamber 29, controls communication with a small cup 37 connected by a hose 43<SP>1</SP> with a breathing mask 8. A second hose 38<SP>1</SP> connects the mask with a larger cup 36 which is urged by a spring against the outside of the diaphragm 35. On inhalation the diaphragm is pushed away from the small cup 37 to permit gas to flow to the mask. On exhalation, the diaphragm is pushed away from the larger cup 36 to occlude the small cup 37, to permit venting of the exhaled gas to atmosphere. The bellows may be manually operated for artificial respiration.
