Title: Improved actuator
IPC: F15B13/10
Filed: 1953-11-24
Abstract: 733,840. Hydraulic jacks. GENERAL MOTORS CORPORATION. Nov. 24, 1953 [Dec. 5, 1952], No. 32526/53. Class 69 (2). [Also in Groups XXVIII and XXX] An actuator is provided with alternative fluid pressure and screw and nut drives each of which can operate the actuator in both directions. A piston 11 secured to a movable actuating rod 15 has journalled therein one end of a screw 20 engaged with a ball nut 44 which is rotatable through a worm drive 55, 62 by a reversible electric motor 68, but which is adapted to be held from rotation by a magnetic brake and clutch mechanism (not shown) when the motor is de-energized. A rod 29 which is splined to screw 20 and is journalled at 37 in the actuator casing carries a disc brake 31 which when the fluid pressure circuit is de-energized is urged into engagement with the end 32 of the casing by a spring-loaded piston 37 so locking the screw. The fluid-pressure circuit is arranged so that on admission of fluid to either side of piston 11 through ports 60, 61 fluid is simultaneously admitted through port 40. This releases brake 31 so allowing the screw to rotate and the piston 11 to move. With the brake 31 operative and the screw thereby held from rotation, rotation of nut 44 by the motor 68 again effects movement of the piston and the rod 15. In a modification (not shown) the disc brake 31 may be replaced by a dog tooth arrangement.

Title: Improvements in and relating to extrusion presses
IPC: B21C31/00
Filed: 1952-12-23
Abstract: 734,039. Extruding. SCHLOMANN AKT.- GES. Dec. 23, 1952 [Jan. 10, 1952], No. 32557/52. Addition to 702,505. Class 83 (4). In a device of the kind described in the parent Specification, the bores of the two billet containers 5, 6 are of different cross-sectional areas and during extrusion the additional plunger 20 acts in one direction only. The billets 22, 23 are extruded simultaneously through a die orifice 4 by rams 1, 10 respectively. The ram 1 is stationary and the containers 5, 6, supported in a housing 7, are movable. The ram 10 is moved by the main plunger 9 and its pressure on the billet 23 causes the downward movement of the containers and hence the extrusion of both billets. Relative movement of the plunger 9 and container housing 7 is transmitted through racks 13, 14 to a pointer 17 and this controls the exhaust of pressure fluid from the cylinder 21 of plunger 20 which thus controls the movement of the containers so as to ensure that the rate of extrusion is the same for both billets. The billets 22, 23 are of equal volume. The press is preferably used for cable sheathing.
