Title: Improvements in or relating to a safety means for use in a system for controlling a fluid actuated device
IPC: F16K17/18
Filed: 1956-02-28
Abstract: 785,179. Machinery safety devices. ROSS OPERATING VALVE CO. Feb. 28, 1956 [March 18, 1955], No. 6142/56. Addition to 744,581. Class 80 (4). A safety valve according to the parent Specification for shutting off the supply to a fluid-actuated device (not shown) in the event of non-synchronous operation of two spaced hand-operated valves 12 controlling the device, thereby preventing an operator " tying down." one of the hand valves, is modified by the addition of a pair of one-way restrictions 51 and a by-pass conduit 52 with an adjustable restriction, in order to delay build-up of pressure in chamber 48 when a valve 12 is opened and so prevent minor discrepancies in the movement of the hand valves causing safety valve cut-off. The restrictions also reduce the sensitivity of the valve to supply pressure variations. As in the parent Specification, fluid passes from chambers 48 past interconnected ball valves 39 to a chamber 33 connected to the actuated device, the valves 39 being located in slidable valve members 26 inward movement of which, due to non-synchronous movement of valves 12, connects chamber 33 with vents 32. Each member 26 has therein a flared portion reducing the pressure drop across the ball 39 when positioned therein. The conduit 52 interconnects the chambers 48 and so by-passes the ballvalves 39 and chamber 33. It is preferably small enough to ensure appreciable friction losses, and has an adjustable restriction formed by a screw, Fig. 2 (not shown). Each restriction 51 comprises a slidable member 55 spring- loaded against a valve seat and having a central passage terminating in a restricting T-shaped passageway, the T-shape preventing the fluid from impinging on the ball 39. When the corresponding valve 12 is turned to exhaust, fluid in chamber 48 forces member 55 away from its valve seat so that fluid flows unrestricted through passages formed by the flat sides of the member 55.

Title: Portable cooking unit
Inventor: SCHULZE WILLIAM M
IPC: A47J37/07
Filed: 1970-02-10
Abstract: 1,242,371. Portable cooking unit. W. M. SCHULZE. 10 Feb., 1970 [11 Feb., 1969], No. 6380/70. Heading A4D. A portable cooking unit has a firebox with inner and outer walls separated by an air space. The inner wall is perforated by a limited number of openings 36 near its base which supply air to the crumpled paper fuel within. The air is drawn down from the open top of the air space and hence keeps the outer wall cool. Additional air may be supplied by optional vents 37 near the base of the outer wall. Flameless combustion of the paper is promoted by the damping effect of the grill rack 38, whose lower grate is covered by a non- porous layer such as aluminium foil, the same being seated on top of the firebox and covering about 75 to 90% of its area. This non-porous layer restrains fat from dripping into the fire and moreover shields the food from any smoke so formed, thus preventing the deposition of carcinogens. The grill rack 38 has upper and lower grates 40 and 39 respectively. The upper grate may be hooked selectively under any of the bars 49 to accommodate various thicknesses of food. Handles 41 and 42 are provided on the grates and may be telescoped in for reduced size during transport and storage which is effected in the enlarged air space 32. The projections 47 serve to locate the grill on the firebox and also can act as feet. The firebox has hinged covers (16) and (17), see Fig. 2 (not shown), which are hollow for the storage of paper. An insulated chest (52), made for example of expanded plastics such as polystyrene or polyurethane foam, may be provided to contain food during transport, its lid being hollow and in two parts to contain cutlery and crockery. An alternative embodiment has a single-walled firebox with a grill rack which covers the entire top but with open spaces (65) and (66) scalloped from the end walls, see Figs. 6 and 7 (not shown). External carrying handles may be provided.

[Also in Groups IX and XXXVI] An electrical strain gauge comprises a fine wire wound in zigzag about insulating anchorages rigidly projecting from an insulating support to which the wire is secured e.g. by glue. In Fig. 1 an insulating e.g. paper support 5 is fixed on a frame 4 carrying pins 3 piercing the paper, about which the strain gauge wire 2 is continuously tension wound from an unwinding device 1 adapted for hand or machine traverse, in which a spool 7 having a spring- operated brake 9 is rotatably mounted in a frame 6 to feed wire through a hollow needle 8. The pins are staggered so that the distance therebetween exceeds the spacing between adjacent legs of the winding, and the diameter of the needle. The winding is secured to the support with glue, soldered to terminal tags, and when the glue is dry the frame and pins are removed. The remaining holes at the bends are filled with a setting material, e.g. glue, or thermosetting cement, to form rigid anchorages supporting the winding. The gauge wire may be covered by a protective sheet 16 of e.g. paper. In modifications Figs. 5 to 10 (not shown) the adjacent legs of the winding may be separated by an interleaved or ribbed insulating sheet, or the winding anchorages may be integrally preformed on a support stamped from insulating material e.g. paper. The gauge may comprise plural insulated layers superimposed at an angle or mutually offset by a fraction of the winding pitch.
