Title: Improvements in or relating to film cassettes
IPC: G03B42/04
Filed: 1956-09-10
Abstract: 807,478. Catch fastenings. CEAVERKEN A. B. Sept 10, 1956 [Sept. 10, 1955], No. 27555/56. Class 44 [Also in Group XX] A film cassette, particularly for X-ray films, comprises a cover hinged along an edge to a case, a spindle having between its ends a projecting tongue adapted to be located in the path of a locking edge of the cover, the spindle being journalled in a frame mounted in the case, a radial arm secured to the spindle, and a spring which - maintains the tongue in said path, the tongue being displaceable against spring action by the locking edge when moving the cover to a locked position, being returned after the displacement, by the spring into locking engagement with the locking edge and being displaceable from locking engagement to free the cover by moving the radial arm against the spring. As shown, the cassette comprises a casing 2 which carries a frame 1 defining a compartment in which an X-ray film 9 is housed between fluorescent screens 7, 8. Hinged to the casing at 3 is a cover 4 carrying on its underside a pad 6 of elastic material (e.g. foam plastic) for pressing on to the film 9. During the closure movement of the cover, a lip 14 thereon engages a lug 13 on a pivoted pin 11 and turns this lug clockwise against a spring 24, attached to the frame 1 and urging an arm 15 extending radially from one end of the pin 11 against the underside of a pivoted arm 18 until the cover lip 14 slips off the lug 13 which thereupon is returned by spring 24 to its Fig. 2 position to keep the cover closed. The cover is opened by lifting the arm 18 provided for this purpose with a finger grip 21, so that the lug 13 again pivots clockwise and slips off the cover lip 14; the cover then springs up under the resilience of the pad 6 and the spring 24 returns the lug and the operating arm to their locking positions. In another form, the arm 18 is attached to the pin 11 and is acted upon by the spring 24 so that to release the cover it is neccessary to depress arm 18. The cover, in a further form, has an inturned lip for engagement with the locking lug on pin 11, and the arm 18 is attached to the pin and must be lifted against spring action to release the cover.

Title: Improvements in master controls for hydraulic power transmission mechanism
IPC: B60T11/22
Filed: 1933-10-16
Abstract: 427,554. Hydraulic transmission of power. HYDRAULIC BRAKE CO., 84, West Hancock Avenue, Detroit, Michigan, U.S.A. Oct. 16, 1933, No. 28566. Convention date, Oct. 17, 1932. [Class 69 (ii)] [See also Group XXXIV] In a hydraulic power transmission system such as that used with hydraulic brakes on vehicles in which a piston reciprocates in a master cylinder the piston controls a valvo mounted between the master cylinder and a reservoir and also another valve mounted between the cylinder and the conduits. In the form shown the piston 12 is actuated by a handle 13 and piston rod 20 which may be retracted by a spring 21 independently of the piston. A spring 24 normally maintains the piston in its rear position in contact with a stop 25. An extension 27, to which a valve control rod 28 is secured, projects from the front face of the piston the rod 28 being guided by an aperture in a stamped plate 28a. In the position of rest the end of the rod 28 lies in a box 30 in open communication with the cylinder 11 and also in communication with the conduits 14 through a passage controlled by a spring pressed ball valve forced off its seat by a tail 37 on the rod 28 ; the bore 30 also communicates with the reservoir 10 by a passage way 39 valve chamber 40 and port 41. A cup shaped valve 42 is, in the position of rest, pressed away from its seat by a spring 44. The valve has a depending flange which lies within a cup 49 thus being prevented from flaring outwardly. A spring, stronger than the spring 44, pushes the valve away from an operating element 54 adapted to be engaged by the upper part of the rod 28. In operation, as the piston is forced down the member 54 is forced upwards compressing the spring above it and forcing the valve 42 on its seat, thus closing the connection with the reservoir. Lost motion is provided in the operating sequence to permit some manufacturing tolerance. The initial movement of the piston also carries the tail 37 free of the ball valve which seats itself until the pressure of the fluid in the cylinder forces it off its seat and opens the passage to the wheel cylinder pistons. On releasing the pressure on the piston the ball returns to its seat trapping the liquid in the conduit system and the reduction of pressure in the cylinder causes the valve 42 to lift, the cylinder thus filling from the reservoir ; in the final position of the piston the tail 37 lifts the ball valve and opens the connection to the conduits and wheel cylinders, the valve 42 also being permitted to remain open as its actuating member rides clear of the rod 28. Specifications 280,502 and 305,994, [both in Class 103 (i)], are referred to.
