Title: Improvements in breathing apparatus
Inventor: JONES LEON
IPC: A62B9/02
Filed: 1958-05-19
Abstract: 854,149. Respiratory apparatus. ROBERTSHAW-FULTON CONTROLS CO. May 19, 1958 [Aug. 1, 1957]. No. 16052/58. Class 81 (2). Breathing apparatus comprises a face mask 18 supplied with gas which is maintained at a predetermined pressure in accordance with altitude under the control of a valve 14, which is responsive to decrease in atmospheric pressure, air exhaust valve 26 which is opened in response to exhalation by the user and is compensated to eliminate the effect of pressure variations due to changes in atmospheric pressure by means responsive to variations in the pressure of gas supplied to the mask and a relief valve 34 for venting the mask to atmosphere at a predetermined pressure therein. Respiratory gas is supplied via a pressure reducing valve 10, a lung-controlled demand regulator 14 to a mask or helmet 18. The regulator which may be mounted on the mask 18 is responsive to decrease in atmospheric pressure to maintain a predetermined oxygen pressure. A check valve 24 prevents flow of gas to the regulator 14 from the mask 18 during exhalation. An exhaust valve 26 and a relief valve 34 are connected with or mounted on the mask 18. On exhalation air passes from the mask 18, through a plastic tube to an inlet port 50 (Fig. 4) which communicates with a chamber 58 in the exhaust valve 26. The valve member 68 of the valve 26 includes a ring 74 made of 'Tetton' which resists the adherence of water and thus the formation of ice at low temperatures. The ring 74 is fixed to a support 76 which may be made of aluminium and which has a recess of tapering cross-section so that its upper wall is inclined to the plane of a knife edge 70 formed by a silicon rubber seating ring 66. Ears 80 on the support 76 have elongated slots 82 which receive a pin 84 fixed to one casing portion 38 of the valve thus pivotally mounting the valve member 68. An expansible chamber 95 communicates with the demand regulator 14 through conduits 112, 114 and is bounded by a supporting wall 88 and a diaphragm 92 which is pressed against the valve member 68 by a spring 100 using it to closed position. On exhalation, the increased pressure in the chamber 58 overcomes the spring 100 and air is vented through the exhaust part 2. The relief valve 34 is positioned in the supporting wall 88 and comprises a valve member 126 which is opened against a spring 132 to vent gas to atmosphere from the expansible chamber 95 through holes 124, 122 if the gas supply pressure becomes excessive. The materials forming the valve and its casing are chosen so that heat is retained and heat from exhaled air is utilised to prevent freezing of the valve at low tempertures.

Abstract: 770,603. Vehicle wheels. WOOD, E. L. June 9, 1955 [Oct. 22, 1954], No. 16587/55. Class 144 (1). A wire spoke simulating wheel trim comprises an outer annular trim ring 23 and a central hub element 24 interconnected by spring engagement with a spring wire spokesimulating element 21, 22. As shown, the spoke simulating element comprises two coaxial, angularly offset annular, eight-pointed star-shaped members 21, 22, of stainless or plated spring steel wire the outer peripheral ends 26 of which are bent to hook shape and lie in a plane offset from that of the inner peripheral ends 27. The hooked ends 26 of the spoke elements snap engage the rolled inner peripheral edge of the trim ring 23 and the inner ends 27 of the spoke elements are sprung into a radially outwardly and axially inwardly facing groove 240 of the hub element, the latter comprising an inner groove defining member 29 and an outer ornamental ring 28. To assemble the wheel trim, the spoke elements 21 and 22, the spokes of one of which are slightly bowed to permit overlap of the two elements with their peripheries in circumferential alignment, are first placed on a mandrel 30, Fig. 13, with their inner ends 27 looped over inclined locating pegs 31 on the mandrel. The trim ring 23 is then forced into snap engagement with the hooked spoke ends 26 by a die 33. The assembled spoke and trim ring unit is next placed on a plain mandrel 32, Fig. 18, and the die 33 operated to depress the trim ring 23, and thereby the outer periphery of the spoke elements, to cause the inner periphery of the spoke element to expand resiliently in diameter sufficiently to enter the groove 240 of the hub element. Release of the die 33 causes the spoke elements to spring firmly into engagement with the groove 240. In an alternative method the die 33 acting on the trim ring 23 may be replaced by a ring acting on the spoke elements.
