Title: Improvements in hydraulic operating systems
IPC: B60T11/22
Filed: 1938-03-25
Abstract: 501,312. Hydraulic transmission of power; clutches ; brakes. GENERAL MOTORS CORPORATION. March 25, 1938, No. 9165. Convention date, March 31, 1937. [Class 69 (ii)] [Also in Groups XXIV and XXXIV] A hydraulic master cylinder for operating brakes, clutches &c. comprises a seal through which the plunger reciprocates, a one-way valve opening from the reservoir to the high pressure side of the seal and a passage connecting the reservoir to the low pressure side of the seal, the plunger being constructed to connect the passage and the high pressure side of the seal when the plunger is retracted. The cylinder part 11 is secured by a bracket 13 and plate 17 to the too-board 21 of a vehicle. The plunger 29 slides through a rubber sleeve 35 bonded to a metal sleeve 33 having an end flange 37 secured by the cap 27 and abutting on a disc 57 between which and a spring seat 55 is a rubber seal 59 engaged by an expander 61 and spring 63. The sleeve 35 facilitates the axial alignment of the plunger. A rubber seal 41 is disposed between the sleeve and the cap 27. The plunger has a reduced end 87 that normally extends through the seal 59 as in Fig. 1, to connect the pressure cylinder proper 53 with a reservoir 49 through recesses 47 in the end of tube 33 and passage 65. A spring-urged one-way valve 79 is disposed between the reservoir and the cylinder 53. When the phmger is moved to apply pressure, the passage 65 from the reservoir to the cylinder 53 is cut off as in Fig. 2. During the return of the plunger, suction causes flow of liquid from the reservoir to the'cylinder through the valve 79, the excess liquid as it subsequently returns from the pipe-line 99 flowing back to the reservoir through the passage 65. As shown, there are two return springs arranged in series, an inner spring 91 seated at its ends respectively on the plunger end 87 and on a cage 83 and an outer spring 105 seated on the end 82 of the cage and on a valve 103 at the end of the cylinder. This arrangement of springs prevents an excessive spring pressure at the end of the stroke with a relatively short cylinder. In operation the spring 91 is deflected first. Rotation of the plunger is prevented by engagement of a pin 89 in a slot in the cage 83 or when a single spring is used in a slot in a tubular part 109, this part then serving as a guide for the plunger. The valve 103 comprises a metal cap seated on the cylinder end by the spring 105 and lifting to permit return of the liquid and containing a rubber element serving as an outlet valve. The Specification as open to inspection under Sect. 91 describes also the brake &c. operating cylinder and adjusting device described in Specification 495,748, [Group XXXIV]. This subject-matter does not appear in the Specification as accepted.

Title: Improvements in and relating to mereury vapour rectifiers
IPC: H02H7/127
Filed: 1928-03-27
Abstract: 287,877. Akt.-Ges. Brown, Boveri, et Cie. March 28, 1927, [Convention date]. Vapour apparatus, arrangements of.-In a device for protecting mercury vapour rectifiers having anodes provided with grids, the occurrence of a short circuit on the direct current side of the rectifier causes such a voltage to be applied automatically to all the grids as to cause at least those associated with the positive anodes to become negatively charged with respect to the cathode. In the two examples illustrated, the the supply transformer 1 is connected to a pair of anodes 3 disposed in shields 5 and associated with grids 4 connected through current-limiting resistances 6 to the contacts of the switch 11. In the case of Fig. 1, the switch is controlled by relays 8, 9 energized respectively by a current transformer 7 in the primary circuit of the main transformer and by the load current so that under excess current conditions the switch 11 is closed thus connecting the grids to the negative side of a battery 10 the positive side of which is connected to the cathode. In the case of Fig. 2, under similar conditions, the grids are connected to opposite anodes so that a negative charge is applied to the grid associated with the anode which is positive. In a third arrangement descrbed. negative potentials for the grids are derived from a potentiometer connected across the D.C. terminals of the system. Tha relays may be provided with time lag devices, and with resetting devices operating either with or without time lag on normal circuit conditions being restored, or they may be replaced by manually-operated means for effecting the grid circuit connections.

Title: Improvements in or relating to hydraulic servo control systems
IPC: B23B47/22
Filed: 1949-04-11
Abstract: 689,312. Fluid-pressure servomotor-control systems. GLENNY, A. P., SPENCER, D. L., and SPERRY GYROSCOPE CO., Ltd. March 31, 1950 [April 11, 1949], No. 9777/49. Class 135. A hydraulic servo-control system applicable, e.g. to an automatic system for controlling the direction of flight or the attitude of an aircraft, comprises a power piston 4 connected to a control surface of the aircraft, the opposite sides of the piston being interconnected through a by-pass controlled by a ball valve 11, and the opposite ends of the cylinder 1 connected through pipes 2, 3 to a pressure liquid supply valve 6. The pipe 3 has a waste ball valve 10. Thus, if the supply through the pipe 3 fails the valve 11 opens the by-pass and the valve 10 opens to connect the lower end of the cylinder to waste. The flow of pressure liquid to the pipe 2 is regulated by a control valve 7 connected by a wire 7a to a pulley 8 mounted upon a shaft connected to a constantly-driven motor through an electromagneticallycontrolled friction clutch, the current to which is regulated according to the deviation of the aircraft from its desired position. When the valve 7 is raised, pressure liquid flows to the upper end of the cylinder and moves the piston downwards by virtue of the greater area of the upper side of the piston exposed to liquid pressure. Downward movement of the valve 7 opens the upper end of the cylinder to waste and, when the supply of pressure liquid fails, permits manual operation of the power piston 4. The sectional area of the piston rod may be about one-half of that of the piston. In a modification, a by-pass between the opposite sides of the piston is provided by arranging a definite clearance between the piston and the cylinder and providing the piston with a groove for a rubber sealing ring. This construction permits manual operation of the piston.

Title: Biaxially orienting tubular films of thermoplastic material
IPC: B29C48/91
Filed: 1966-03-07
Abstract: 1,096,127. Biaxially orienting tubular films. UNION CARBIDE CORPORATION. March 7, 1966 [March 12, 1965], No. 9811/66. Heading B5B. A preformed flattoned tubular film 20 (Fig. 3) passes through the nip of squeeze rolls 28 and is reinflated to form a secondary bubble which is drawn vertically upwards through a cylindrical radiant heater system 30 comprising cylindrical radiant heaters 42, 44, 46 and 48 spaced apart from each other and having a longitudinal central passage for the tubular film therein. Each of the heaters includes a series of electrical resistance elements 65 equally spaced about the circumference of the heater and controlled by a known transformer type of control. The internal wall of each heater is preferably provided with screening 63 and the diameter of the central passage of each heater is sufficiently large to allow the tubular film in its radially distended condition to pass through the passage with ample clearance. A high velocity stream of a cooling gas, such as air, is introduced adjacent to the upwardly moving column of tubular film, so as to cause the gas to impinge upon the tubing being heated and is also introduced in the vicinity of the draw zone, by means of an air ring 50 between the heaters 44, 46 and a blower 51. The air ring has a slot orifice which directs the stream of air upwards and as the tubular film 20 advances towards the squeeze rolls 34 it is surrounded by an upwardly moving stream of air composed partly of ambient air drawn up the heater passage by the upward movement of the tubing, by the chimney effect of the heaters and by the induction effect of the high velocity air stream from the air ring 50. The heaters are situated and adjusted so that the air stream initially at room temperature always remains at a temperature below that of the tubular film in the draw zone, thus serving to control the temperature of the film and to prevent overheating of the film in the draw zone. It is preferred to rapidly cool the expanded tubular film after the expansion is completed to prevent the annealing of the film and thereby to produce film having maximum heat shrinkage for packaging purposes. For this purpose an air ring 53 may be provided to rapidly cool the expanded tubular film. In addition an exhaust ring 54 having iris diaphragm controlled openings 56 and 58 may be provided. The inflated tubular film 20 is drawn through the heater system 30 and is flattened by the squeeze rolls 34 which are driven at a peripheral speed higher than that of squeeze rolls 28 either to pick up slack formed during biaxial stretching or to impart additional machine direction stretch. The film may, if desired, be annealed by reinflation and heating in the apparatus 72, 74, 76.

Abstract: 1,118,653. Gas turbine combustion chambers; gas turbine plant. GENERAL ELECTRIC CO. March 7, 1966 [March 11, 1965], No. 9815/66. Headings F1G and F1L. A toroidal gas turbine combustion chamber 49 has a compressed fuel/air mixture introduced thereto, the mixture being mixed within the chamber with substantially completely burnt combustion gases so as to heat the fuel component above its oxidation temperature and maintain flameless combustion. Flameless combustion is defined as burning of the fuel/air mixture uniformly throughout the combustion chamber without propagation of a flame front. Liquid fuel is added to the air entering a centrifugal compressor 42 by a carburettor 48. The compressed fuel/ air mixture passes through a diffuser 51 to enter the toroidal combustion chamber 49 at a velocity of about 100 ft/sec. The entering mixture is heated by recirculating combustion gases and remains in the chamber 49 at least 0À1 seconds so that flameless combustion to about 800 or 900‹C. proceeds. The combustion gases leaving the chamber drive an inward flow turbine 43 integral with the compressor 42 and connected to a power output shaft 44. A spark plug 52 is used at starting. A cooling air-flow is circulated over the turbine 43 at 46. Water may also be injected into the fuel/air mixture to assist cooling. In a modification, Fig. 2 (not shown), the compressor (31) and turbine (34) are both axial-flow and the combustion chamber (33) is provided with an annular plate (36) having holes (37), the plate assisting the recirculation of the combustion gases. A similar plate may be provided in combustion chamber 49, the chamber (33) may also be insulated to reduce heat losses. Gaseous fuels may be used in the invention. The fuel may be introduced into the diffuser downstream of the compressor.
