Title: Tire building drum
IPC: B29D30/24
Filed: 1959-05-21
Abstract: 870,413. Collapsible tyre-building drums. FIRESTONE TIRE & RUBBER CO. May 21, 1959 [June 5, 1958], No. 17289/59. Class 144 (1). A collapsible tyre building drum 10 comprises a number of large segments 16 interspaced by an equal number of small segments 17 which are supported and linked-together so that the small segments are movable radially inwardly followed by the large segments until the latter abut each other to form a continuous surface completely enclosing the small segments, Fig. 4. As shown, each large segment 16 is pivotally linked, adjacent its chamfered leading edge 31, by a straight arm 60 to an actuating sleeve 25 rotatably mounted on a hub 18 which is keyed to a drive shaft 19. Each large segment 16 is additionally pivotally linked, adjacent its square-cut trailing edge 30, to the sleeve 25 by a cranked arm 67. The small segments 17 each have radially inwardlyextending lugs 50, 51, the ends of which straddle, and are pivotally pinned to, the elongated ends 41 of spokes 40 which radiate from the hub 18. The extensions 50, 51 are also pivoted on pins 68a and 68, intermediate their ends, to bosses 16<SP>1</SP> and 69 on the underside of the trailing edge of the adjacent large segment, the pin 68 of the boss 69 being that to which the cranked arm 67 is pivoted. The actuating sleeve 25 is normally keyed to the hub 18 by spring-loaded ball detents 45 but provision is made for braking the sleeve 25, or the shaft 19 whereby the inertia of the unbraked parts overrides the detents to effect relative rotation of the sleeve 25 on the hub 19 and thereby effect collapse or expansion of the drum. In the expanded position of the drum, the arms 60, 67 extend nearly radially with their outer pivots 61, 68 in slight over-centre positions, Fig. 2, so that the drum will not collapse on radial pressures exerted during tyre-building operations. In the collapsing operation, effected by braking the actuating sleeve 25, the small segments 17 are swung rapidly inwardly to clear the leading edges of the trailing large segments and thereby permit the subsequent radially-inward movement of the large segments. The rapid inward movement of the small segments is achieved by the mechanical advantage deriving from the relative disposition of the spoke pivot 56 and the large segment pivots 68, 68a along the lugs 50, 51 of the small segments 17.

Title: Improvements in or relating to pressure measuring apparatus
IPC: G01L21/26
Filed: 1962-05-04
Abstract: 1,013,103. Measuring pressure and force. EDWARDS HIGH VACUUM Ltd. May 4,1962 [May 5, 1961], No.17292/62. Headings G1L and G1W. Relates to a pressure measuring apparatus comprising at least one pair of spaced apart elongated surfaces, fixed and movable respectively, a means for maintaining a selected temperature gradient along at least one of the surfaces of the or each pair whereby thermal gas currents are developed in a known gas surrounding the surfaces which produce radiometer forces at the movable surface(s) the net force being proportional to the gas pressure, the magnitude of the temperature gradient, the known nature of the gas and a selected relative spacing of the surfaces, and comprising a means to measure the force developed which will be a measure of the gas pressure since the other three factors are known and fixed. As shown Fig. 6 a movable hollow aluminium cylinder 12 providing one surface is disposed within a stationary glass housing 13 providing a second surface the lower part of which is heated to 500‹C. and the upper part may be at ambient room temperature or cooled. Thermal gas current are thereby developed and produce radiometer forces causing cylinder 12 to lift, which can be measured as a change in weight by a spring balance or electric balance 14. Alternatively the top of the cylinder 12 may be at the higher temperature in which case the net force will act downwardly. A plurality of tubes placed one within the other (Fig. 8 not shown), may be used, alternate tubes being fixed and movable respectively. The radiometer forces utilized are (i) molecular flow force at pressures below 10<SP>-2</SP> m.m. mercury column (ii) tangential thermal slip force at 10<SP>-2</SP>m.m, upwards (iii) buoyancy force at 1m.m. mercury column upwards. A mathematical analysis of the forces is given.

Filed: 1925-07-06
Abstract: 250,893. Sharp & Dohme, (Assignees of Dohme, A. R. L.). April 16, 1925, [Convention date]. Acyl resorcinols, such as propionyl, butyryl, valeryl, caproyl, heptylyl, caprylyl, dodecylyl, isobutyryl, isovaleryl and isocaproyl, are prepared by gradually adding resorcinol to a hot mixture, preferably at 125-145‹ C., of zinc chloride and the corresponding fatty acid, the weight of zinc chloride being less than half that of the fatty acid. The reaction is carried out at 125-145‹ C. and preferably between 130 and 140‹ C., while the weight of resorcinol is advantageously not in excess of one-third that of the fatty acid. An example shows the preparation of normal caproyl resorcinol, the weight of resorcinol and zinc chloride being respectively one-third and one-fifth that of the caproic acid. The product is washed, distilled in vacuo, and may be further purified by redistillation and crystallization from a mixture of toluene and petroleum ether. Specification 250,892 is referred to.
