Patent GB-1388019-A (GB)
Title: Die-casting machine
IPC: B22D17/10
Filed: 1972-04-18
Abstract: 1388019 Pressure die casting machines IDRA-PRESSEN GmbH 18 April 1972 [29 April 1971] 17990/72 Heading B3F A cold-chamber die casting machine in which metal is forced into the mould in phases comprises a multiplier 1, a pressure reservoir 7 connected to the multiplier via a blocking piston 13, and a 4/2-way valve 6 which controls a shut off valve 5 in a line 10, 9, 8 connecting a space 11 in front of the blocking piston to a space in front of the pressure reservoir 7. During the first phase, fluid pressure from a pump P is supplied to a bore 3 in the multiplier piston 1 and acts on the press piston 4 to cause a relatively slow movement thereof. After a given time or after the piston 4 has reached a given position, the valves 6 and 12 are actuated. Operation of the valve 6 actuates the shut off valve 5 to permit pressure medium from the reservoir 7 to flow to the space 11. The increased pressure now acting on the piston 4 causes the piston 4 to move more rapidly during the second phase of the metal injection process. The speed may be controlled by adjustment of a spindle 34. When the mould has been filled, the pressure in the space 11 rises and causes a valve 15 to change over. This opens the space 16 to atmospheric pressure, this permitting the blocking piston 13 to move to the right and the pressure fluid in the reservoir 7 to act directly on the multiplier piston 1 which begins to move to the left as soon as the counter-pressure in the space 20 has been overcome. In another embodiment the valve 5 is combined with the blocking piston 13 and in a further embodiment the valve 12 is omitted, its function being carried out by the valve 6.
Patent GB-180261-A (GB)
Abstract: 180,261. Willems, G. H. Sept. 7, 1921. Stands and jacking- devices for vehicles.-A vehicle-raising device and stand of the tip-over type has a member engaging a forward part of the vehicle and is arranged to move it forwardly, so that the action of gravity during the latter movement causes continued forward movement whilst a strut lifts the rear of the vehicle. Fig. 1 shows one form of the stand. On running the vehicle forwards along the track 11, the front axle engages in the saddle of the pivoted leg 16 maintained at the right height by heels 18. The front axle also engages the arm of a dog 26 attached to a draw rod 23 in such a way that when the saddle has passed forward of the dead-centre over the shaft 14 the rear legs 15 are raised to engage the rear axle of the vehicle. When the vehicle is raised, further forward motion is prevented by the base of forward extension 16' of legs 16 resting on the floor. In order that the vehicle may be run out of the stand, traction plates 30 are pivoted on the track 11 at their rear ends and can be raised to support the rear wheels by a lever 33, which operates a cam 31 engaging corrugations on the traction plate. In Fig. 3 a modification is shown in which the rear legs are replaced by a revoluble roller 37 mounted on bearings within the track, whilst on the rear axle is provided a leg element 41 having its lower face inclined downwards towards the rear so that its lower part is below the level of the top of the roller when the vehicle is on the track.

Abstract: 801,109. Automatic stop motions for looms. SULZER FRERES S.A. June 14, 1956 [June 24, 1955], No. 18480/56. Class 142(2) To enable the weaver to verify that a fault has been correctly remedied, a loom is stopped with the slay at beat-up position immediately on re-starting. When a handle 69 is turned anti-clockwise to disengage the pattern mechanism from its drive, an arm 56 rides out of a notch 67 in a disc 66, thereby turning a shaft 55 to stop the loom (if the shaft has not already been turned by an automatic stop motion or another manual control handle); at the same time, a lever 57, previously resting against a flat 65, is moved along the shaft, thereby bringing a roller 58 clear of a stop 62 and into the path of a cam 54, the roller being raised into contact with the cam by a spring 59, in which position it lies against the side of the stop 62. When the pattern mechanism has been reclutched to its drive by returning the handle 69 to the position shown, the loom can be started by turning the shaft 55; rotation of the cam 54 then depresses the roller 58, causing the lever 57 to turn the shaft 55 by striking a pin 181, the mechanism being timed to bring the loom to rest at front centre. As the lobe of the cam 54 passes the roller 58, a spring 63 slides the lever 57 back to the position shown. In a modification, the handle 69 has an intermediate setting at which the pattern mechanism is declutched without bringing the stoping mechanism into operation. Specification 762,050 is referred to.
