Title: Improvements in and relating to pressure responsive hydro-pneumatic apparatus
IPC: B01D33/00
Filed: 1959-12-29
Abstract: 908,072. Automatic control of filters. PONSAR, Y-M. Dec. 29, 1959 [Dec. 31, 1958], No. 44149/59. Class 38 (4). [Also in Groups I and XVIII] Liquid level indicating apparatus comprising a U-tube filled to a predetermined level with a liquid L of negligible vapour pressure, e.g. mercury, and consisting of primary and secondary vessels V 1 , V 2  interconnected by a channel 10 and a reference pressure tube 11 (see Group XVIII) is employed for the automatic cleaning of a filtering drum 22 disposed between two liquid volumes having levels 23, 24. Pressures from pressure means 26, 28 corresponding to the liquid pressure heads P 1 , Pr above the pipes 25, 27 respectively are supplied through a pipe 15 and a reference pressure pipe 11 to the vessels V 1 , V 2 . If the filter becomes fouled, the level 23 and the corresponding pressure P 1  rise so that the level of mercury rises in the vessel V 2  to complete the electric circuit to a filter rotating motor 30 and a valve 32 controlling water jets 31. If the reference pressure Pr is maintained above atmospheric pressure, a suction device 14 may be substituted by a restricted orifice.

Title: Improvements in or relating to swaging machines for the internal profiling of tubular workpieces,particularly of barrels for firearms
IPC: B21J5/12
Filed: 1961-12-11
Abstract: 979,311. Swaging machines. GES FUR FERTIGUNGSTECHNIK UND MASCHINENBAU G.m.b.H. Dec.11, 1961 [June 6, 1961], No. 44160/61. Heading B3H. In a swaging machine for internal profiling of tubular workpieces, by hammering on a mandrel whilst the workpiece is gripped between a feeding gripping head and a holderup, a back pressure which is constantly applied to the holder-up is automatically varied, by means of a valve, in accordance with changes in wall thickness and/or the required internal shape. Thus, optimum axial compression to prevent axial metal flow is applied at all times. In operation, the workpiece 21 is gripped in a sleeve 7 of the gripping head 3 and rotated through a worm and worm-wheel drive 8. Feed of the workpiece to and through the hammers 1 is to the left and is effected by hydraulic cylinders 6 mounted on a forging box 1<SP>1</SP> and piston rods 4 attached to the gripping head 3. The holder-up comprises a cylinder 11 and piston 12, whose rod carries a rotatable holderup head 10, and the back pressure is controlled by a pressure setting valve 24, a control valve 27 and associated cam 28 mounted on the gripping head 3 and a follower 29. The cam 29 controls the seating pressure of a valve plunger 30 through a spring 31 which, through a conduit 34, controls the displacement of a spring-loaded piston 32 in the pressure setting valve 27. The piston 32 has an orifice 33 through which a portion of the fluid displaced from cylinder 11 passes to the control valve. The flow rate from and hence the pressure in cylinder 11 is dependent on the position of the face 37 of the piston 32 with regard to the outlet to conduit 25. In an alternative embodiment, the back pressure in the cylinder 11 is controlled by a series of relief valves with different settings which are alternately or successively brought into operation by solenoid operated slide valves in the return conduit which are operated by limit switches in response to movement of the gripping head. The mandrel is carried on a rod 15 which extends through the gripping sleeve 7 to a piston 16 mounted in an hydraulic cylinder 17 which is slidable in a second cylinder 18. The embodiment described is a rifled barrel, and if it is required to form the cartridge chamber, the mandrel must be carried to the left with the workpiece during this swaging stage. Thus the gripping head 7 engages the end face of the mandrel (Fig. 7, not shown) which is moved to the left by the gripping head 7. This is made possible by the provision of a relief valve in the conduit 19, allowing the cylinder 17 to slide in the cylinder 18.

[Also in Division F2] A hydraulic check floor spring comprises a housing 4 having a journal mounting for a stub or socket 7 which engages with a door to be controlled, a two-lobed cam 8 connected to the stub and cooperating via a displaceable beam 12 with a spring assembly or assemblies 13 to provide a restoring force to close the door, means by which the restoring force is modified during the latter stage of closure so that a substantially instantaneous increase in the force occurs, and a second cam 9 connected to the stub and cooperating with a hydraulic dashpot to provide damping during closure, the cam being so shaped that the degree of damping increases as the door closes. Each spring assembly comprises a tubular socket 30, attached to an adjustable abutment 15, within which a rod 32 attached to the beam can slide. A sleeve 34 with a collar 36 slides on the rod and compression springs 38 and 40 abut the collar so that as the door nears its fully open position, all compression takes place in the spring 40 to produce a sudden increase in the restoring force. In a single acting device, only one spring assembly and one of the cam lobes 8 are used. In a modification (Figs. 3 and 4), the relative lengths of the springs 38 and 40 may be adjusted by means of nuts 62, 64 and 66. Also, the maximum angle of opening of the door can be adjusted by means of a socket 68 which can abut the sleeve 34.
