Oct 16, 1950 [June 17, 1949], No. 25178/50. Class 135 A hydraulic jack, suitable for actuating the working tool of an agricultural machine, is controlled by a valve 11 which carries a pin 23 riding in a slot 24 in a sleeve 25 rotatable around the valve and connected to the piston of the jack by means of a forked lever 26, &c. When the manual control lever 22 is actuated, the valve will be given a longitudinal movement due to the co-operation of the pin 23 and the slot 24, the sleeve being held stationary at that moment by the jack piston. Pressure liquid is supplied by an engine-driven pump and will flow in at port 7 to one of the ports 16, 19 which lead to the two sides of the jack, and the liquid exhausting from the jack will flow in at the appropriate port 16 or 19 and out through port 13. The resulting movement of the jack will rotate sleeve 25 and, once again due to the co-operation of pin 23 and slot 24, the valve will be moved longitudinally towards the neutral position. Owing to the overlap on the lands of the valves, flow to the jack will cease and the latter will stop moving before the valve has been fully recentred, and the final recentering movement is given by a leaf spring 27 secured to the valve.

Stamping.-A method of forming corrugations or convolutions in a wall of a container such as a tube or cup-shaped container comprises connecting said container to and filling said container with a fluid from fluid holding means, deforming the container by a forming apparatus whilst continuously varying the volume of the fluid in said container in a predetermined manner, and whilst maintaining the total volume of fluid in said fluid holding means and said container constant. A tubular blank b is placed between die plates 10 and 20 with the blank ends engaging in recesses 11 and 21 respectively in the plates where they are sealed by sealing rings 12 and 22. The die plate 10 is provided with chambers 13 and 15 of predetermined differing diameters, the larger chamber 15 being situated in alignment with the recess 11 and open at the lower face of the die plate. Pistons 14 and 16 operate in the chambers 13 and 15 respectively and a passage 17 in the die plate connects the chambers together and to the interior of the blank. Fluid is supplied to the chambers and blank from a tank 19 via a valve 18a and passage 17a. The blank is vented through a discharge passage 23 in the upper die plate controlled by a solenoid valve 24a. Stops 25 limit the closing movement of the upper die plate which is spring-loaded in its uppermost position. Guide rods 27 attached to the upper die plate carry a cross-arm 28 which supports the large piston 16. The small piston 14 is actuated by a ram 40. In operation, the system is filled with hydraulic fluid from the supply 19 and the ram is lowered to depress the small piston 14 which displaces some of the fluid into the bellows blank b which absorbs it by bulging between spaced ring dies 30. At the end of this phase the ram engages the upper die plate 20 and collapses the die assembly to the bellows-forming position as shown in Fig. 4 wherein the piston 14 is in its lowermost position and the larger piston 16 is withdrawn from its chamber to counterbalance and absorb the combined fluid transfer from the small chamber 13 and the bellows blank. An eccentric cam may be provided between the ram and piston 14 to vary the rate of transfer of fluid volume if desired.

Abstract: 961,438. Unloading film from cassettes. GEVAERT PHOTO-PRODUCTION N.V. July 22, 1960 [July 28, 1959], No. 25685/60. Heading G2A. [Also in Division H5] Apparatus for unloading exposed sheet film such as X-ray film from a hingewise-opening cassette comprises means for opening the cassette, means for gripping the film sheet therein and conveying it to a receiving means. For unloading cassettes in an undarkened room, the unloading mechanism and the cassette are enclosed in a light-tight chamber. As shown, the chamber has a lid 4 which is opened to insert the cassette 1, and can then be locked closed by a lock member 5. The cassette is supported on brackets 2, 3, and the cassette lid 19 can hinge downwards as shown. It has two flap locks 18 in which engage the hooked ends 9 of bars 11; as the bars 11 are moved up and down in a reciprocal motion by arms 14 mounted on a motor-driven shaft 15, the articulated upper hooked ends 9 engage in the flap locks and draw down the lid 19 to open the cassette. Also driven by shaft 15 is a cam 20 and a following roller 21, and thus, through an arm 22 and a connecting bar 24, a pair of curved jaws 23, 30 pivoted together at 32. As the shaft rotates, these are swung into the up position, in which the jaws are caused to grip the end of the film 28. The jaws are then swung down again under the control of cam 20, and during this motion the film becomes introduced between rollers 34, 35. The jaws now disengage, and the film is conveyed by the rollers to a discharge way 36, 37, passing a light seal 38 to the outside of the chamber. When the apparatus is used in an undarkened room, the passage way 36, 37 may be connected directly to a developing apparatus. In a somewhat simplified modification (not shown) the cassette lid is opened by manually operating a lever. The sequence of operations may be controlled and timed electrically, and Figs. (not shown) 8 and 9 give details of suitable circuit arrangements.
