Title: Improvements in or relating to valves for fluid operated motors
Inventor: DAWSON STEWART BRUCE
IPC: F04B9/12
Filed: 1965-12-22
Abstract: 1,131,982. Actuating distributing valves. GIRLING Ltd. Jan.27, 1967 [Dec. 22, 1965], No.54444/65. Headings F1M and F1S. An automatic valve for a fluid operated reciprocating motor comprises a reciprocable actuating member 4, a reciprocable valve member, a link 9 connecting the two members, and resilient means 17 acting between the members, the link being constructed and arranged to shorten and stress the resilient means in such a manner that in operation of the valve, with the valve member in one extreme position, movement of the actuating member in one direction first causes the resilient means to be stressed by shortening the link and then to be released to urge the valve member towards its opposite extreme position, these actions being repeated in the reverse directions on the return stroke of the actuating member, and further comprises stop means 18, 19 for engagement by the link towards each end of the stroke of the actuating member, the stop means acting to cause the link to pivot about its point of connection with the actuating member and thereby positively drive the valve member away from its instant extreme position in the event that the resilient means is unable to overcome the static friction to which the valve member is subject. The stop means may be of resiliently deformable material. The invention is described as applied to a vacuum operated pump.

Title: Photogrpahic apparatus
IPC: G03B7/24
Filed: 1970-11-19
Abstract: 1314609 Cameras and cassettes therefor POLAROID CORP 19 Nov 1970 [19 Nov 1969] 55097/70 Heading G2A A cassette 32 has a temperature-responsive impedance 120 mounted on it, so that terminals on the impedance co-operate with corresponding terminals of an exposure control circuit of a camera when the cassette is inserted therein. Thus parameters of the circuit are automatically trimmed according to variations in the ambient temperature. As shown the cassette contains film units for use in self-developing cameras. The impedance 120 is in the form of a rod-like negative or positive temperature coefficient thermistor, and has terminal or contact areas 122, 124. It is accommodated in a recess in the cassette wall. When inserted into the camera, terminals 122, 124 make contact with terminals 96, 98 which form part of the automatic exposure control circuit Fig.4 (not shown) of the camera. Terminals 96, 98 are carried on a spring member 126 screwed to the bottom cover 16 of the camera, so that the spring action urges them into contact with terminals 122 and 124. The control circuit is of a known type in which scene light is detected by a photo-voltaic cell whose output controls a trigger circuit initiating an exposure for a predetermined period. The circuit contains two resistors (R 1  and R 2 ), one of which corresponds to the impedance 120 and the other which can be adjusted in accordance with the film speed.

Apparatus for corrugating flat asbestoscement sheets comprises two sets of converging endless belts which corrugate the blank and a further set of belts which shape the sheet to the required dimensions. As shown, the first set of belts comprises upper belts 15 and lower belts 17 offset relative to the upper belts, both of these sets converging towards rollers 11 over which these belts pass. The flat sheets are fed through rollers 50 where an emulsion coat from bath 49 is applied and are corrugated between parts 26 and 27 of the belts 15 and 17. The sheets then pass into the second section defined by belts 16, 18 where they are formed to the correct dimensions and trimmed. The upper and lower belts are laterally spaced by half the repeat distance of the corrugations as is shown in Fig. 4 (a section along IV-IV in Fig. 1) and comprise shaping members 22 with material contacting face 23 mounted on chains 16, 18. The upper parts of chain 18 are supported by rigid members 29 and the lower parts of chain 16 press the sheet against shaped supports 24, giving it the correct profile. Extra chains 38 with flat pressing members 39 flatten the edge of the sheet against block 37 for cutting between rotating blades 35 and drum 36. The corrugated sheet is removed from the second section by conveyer 19 which has a similar form to conveyer 18, the spaces between the chains being filled by shaped members similar to supports 24 to maintain the configuration of the sheet.
