Abstract: 123,342. Gray, J., (Reynolds, C. H., and Ayers, A. L. M.). Nov. 6,1917. Turning-gear.-The fly-wheel has a part d mounted loosely on the crank-shaft a and a part c fixed to the crank-shaft, the part d being coupled to the part c after being set in rotation by an electric or other starting-motor. In one form, Fig. 1, the loose part d of the fly-wheel is rotatable in ball-bearings e on the fixed part c. The two parts are normally held in engagement by an axially movable spring-pressed clutch ring f. At starting, the ring f is disengaged by pedal-controlled rollers m, the part d is driven through a friction wheel k, and the ring f is allowed to reengage the part c when sufficient speed is attained. The pedal which controls the ring f may also switch the starting-motor on and off, and may be automatically locked in its depressed position until released by a centrifugal device when the speed of the fly-wheel is sufficient. In a modification, the part d is belt-driven, and the clutch ring is L-shaped in section and engages the face of the part c. In another modification, the rollers m act directly on the edge of the loose part d, which is normally held in engagement with the part c by springs encircling pins on a ball-bearing member slidable on the hub of the part c. Reference has been directed by the Comptroller to Specification 16166/03.

Title: Oxygen therapy system
IPC: A62B7/00
Filed: 1964-04-20
Abstract: 1,034,983. Liquid oxygen vaporizers. UNION CARBIDE CORPORATION. April 20, 1964 [May 9, 1963], No. 16378/64. Heading F4P. [Also in Division A5R] A portable liquid oxygen converter B and a larger liquid oxygen converter A either of which may be used independently, each comprise a liquid storage container with a liquid transfer conduit and a vaporizing conduit, complementary valve assemblies being secured to each container so that the portable converter may be inverted over the larger converter with the valve assemblies mating with each other to interconnect the transfer conduits of each container and vapour venting passages of each container and permit the portable converter to be filled from the larger converter. The converters each comprise a double-walled liquid oxygen container 10, 90 the space between the walls being evacuated and containing insulation material and a gas adsorbent 24, 108. Bursting discs 28, 112 are provided in the outer wall of each container. A liquid transfer tube 34, 118 extends from near the base of each container to a spud 30, 114 which gas-tightly closes a passage 20, 114 at the top of each container. The transfer tube 34 of the larger converter communicates through the spud 30 with a normally closed valve 140 comprising a fixed stem 154 and a movable seat 156 and with a passage leading to a vaporizer 70. The vaporizer comprises helical grooves formed outside an electric heater 72 enclosed in a tube, or heat-exchange coils (Fig. 2, not shown), arranged outside the container and warmed by the ambient atmosphere. Oxygen vapour passes from the vaporizer to the user through a manually controlled valve 44. A working pressure is built up in the container by a heating resistance 56 controlled by a pressure switch which is connected to the spud 30 and is responsive to the pressure in the container. A thermal switch 66 prevents overheating of the container, e.g. when the vessel requires refilling. The fluid transfer tube 118 of the portable converter communicates through a cap 116 with a vaporizer coil 120 which is connected to a breathing mask through a valve 130, and with a normally closed valve 166 through which the converters are interconnected for filling the portable converter. A double-walled tube 100 forming a space around the transfer tube 118 communicates at one end with a vent tube 124 within the container and at the other end with a normally closed valve 168. The valves 166, 168 comprise movable stems 176 and fixed seats 178, so that when the portable converter is inverted over the larger converter, the valves 166, 168 engage with the connecting valve 140 and a similar vent valve 142 to open the four valves. Air is vented from the portable converter through the vent valves as liquid oxygen flows into the container 90. A shielded thermistor 134 in the container 90 causes closure of a valve 122 to prevent exhaust of vapour when liquid oxygen has reached a predetermined level so that as filling continues a working pressure is built up. The portable converter may be used during filling.

Title: Improvements in or relating to articles comprising a non-porous element mounted in a porous member and methods of forming such articles
IPC: B23B27/18
Filed: 1956-05-29
Abstract: 829,948. Moulding powdered metal articles. BITTERLI, J. A., HESSLER, W. G., and FROMMELT, H. A. May 29, 1956 [June 2, 1955], No. 16615/56. Class 87(2). [Also in Groups II, XXII, XXIII and XXIV] A method of fastening a hard element 14 to a porous member 11 consisting of powdered metal, comprises the steps of assembling them so that the element projects from a recess in the member and causing the material of the member to grow in the recess toward and thus intimately and uniformly engage the opposed surfaces of the element. The powdered metal may be of iron with manganese, molybdenum, copper or carbon additions and have a particle size of 80-325 mesh. Sintering takes place at 2050-2300‹F. for from “ to 1 hour. The recesses for the bits may be provided during compacting or by machining after sintering. The recess may be undersize and the body heated to allow the bit to be inserted or may be oversize so that the bit is peened or swaged in place. The recess may be of dove-tailed shape. The body is infiltrated at up to 2100‹F. with copper, brass or bronze, which may have an iron content. The bit may be of tungsten carbide, ceramic, diamond or H.S.S. and may have a roughened surface to increase the gripping effect, which is also enhanced by the shrinkage of the body on cooling. The invention may be applied to milling or planing cutters, saws, lathe, drilling or boring tools, chisels, gears or textile picker fingers. In making a milling cutter, a body of powdered metal 11, Fig. 2, is shaped between dies 22, 24, Fig. 4, and is then sintered. (In a modified moulding apparatus, the powder body is formed by dies 43, 44, Fig. 10, and the recesses are made by projecting plungers 51 into the powder by means of cams 53). After the bits 14 have been placed in position, a slug of infiltrant metal is placed above or below the body and the body heated in a non-oxidizing atmosphere. In a modification, bits 38, Figs. 7 and 8, are locked in bodies 36 each of which is secured in a disc 34 by a tapered pin 39. For making inserts 60, Figs. 11, 12 and 14, for a face-milling cutter 71 the powder is compacted between dies 58, 59. The bit 61 has an overhang 67 so that the face of the bit merges smoothly into a clearance groove 65. Each insert is secured by a pin 74 in a groove 69. A slitter or shearing knife has a single-, or double-, edged or squared rim 110, Fig. 25, secured to a powdered body 112. The body 112 is compacted inside the rim 110 or the rim or body are made in segments. In a modification, the body 115. Fig. 26, is made of two sintered discs bolted together within the wedge-shaped rim 113. Internal or external gears may be made by securing teeth 123, Fig: 29, within a groove in the body 122. A textile picker finger 125, Fig. 30, has a hard metal tip 127.
