Abstract: 802,878. Wheel rims. GOODYEAR TIRE & RUBBER CO. Jan. 15, 1957 [May 4, 1956], No. 1477/57. Class 144 (2). [Also in Group XXIX] In a demountable wheel rim 10 for tubeless tyres which has a radially inwardly projecting rib 19 whereby the rim is clamped, as by lugs 17, to a wheel body 16, an inflation valve stem 23 has its axially inner end 24 clamped, as by a nut 25, in a hole 21 in the rim base with a flange 26 on said inner end in sealing engagement with the radially inner surface 27 of the rim base 13, the valve having an intermediate portion 29 extending axially outwardly parallel with the rim base 13 and terminating in an axially outer portion 30 which entends generally radially inwardly parallel with the rib 19. As shown, the flange 26 of the valve stem is sealed to the rim base by a gasket 28 and the intermediate portion 29 is spaced from the rim base by not more than <SP>1</SP>/ 16  of an inch. The outer end 30 of the valve stem extends between two lugs 39, 40 which project inwardly from the rib and are themselves received in a slot 36 in the wheel body for driving engagement between the rim and wheel body. The lugs 39, 40 prevent rotation of the valve stem in the hole 21. A conventional valve core 35 is housed in a tube 34 which detachably screws into the end 30 of the valve stem for ease of replacement in the event of damage to the tube 34.

Filed: 1975-01-14
Abstract: 1475832 Reciprocating conveyers having a warning device CROSS EUROPA-WERK GmbH 14 Jan 1975 1607/75 Heading B8A Pressure is fed by a flexible line 61 to a joint between a face of a drive member 25 of conveyer bars 2, 2, and the face of a bracket 54. If the parts 25 and 54 work loose, pressure escapes and an electric circuit is energized by the operation of a pressure switch 64. The drive member 25 is rigid with a member 18 which is slidable on guide rods 19, 20. A drive element 14 rigid with an endless chain 4 driven by a motor 13, is slidable in a slideway in the member 18. Thus rotation of the chain 4 produces backwards and forwards movement of the member 18 on the guide rods 19, 20 and corresponding movement of the bars 2, 2.

Title: Improvements in or relating to the manufacture of high antiknock gasoline hydrocarbons
IPC: C07C2/62
Filed: 1940-01-26
Abstract: 552,282. Hydrocarbons. TEXACO DEVELOPMENT CORPORATION. Jan. 26, 1940, No. 1652. Convention date, March 8, 1939. Drawings to Specification. [Class 2 (iii)] Gasoline hydrocarbons are obtained by contacting propylene in the liquid phase at a temperature below 100‹F. with a substantial molar excess of a low-boiling isoparaffin, e.g. isobutane or isopentane, in the presence of concentrated sulphuric acid of greater than 90 per cent. strength and with an added 5-15 per cent. by weight, based on the propylene, of a butylene or polymer thereof. The presence of the butylene, preferably isobutylene, serves to promote the alkylation reaction. According to the example, a refinery gas is distilled to give a C 3  fraction containing propylene and a C 4  fraction consisting mainly of isobutane and C 4  olefines. The propylene is then separated from the C  3  fraction by absorption in concentrated sulphuric acid and the resulting solution, to which further acid may be added, is heated while the C 4  fraction is introduced, together usually with additional isobutane. The reaction products are then treated for recovery of the gasoline hydrocarbons formed. The acid absorption step may be omitted and the alkylation process carried out under sufficient pressure to maintain the C 3  hydrocarbons in the liquid phase.

Abstract: 366,272. Dispensing liquids. GAFKA, W., 16, Lerchenfelderg³rtel, Vienna. Jan. 22, 1931, No. 2174. [Class 116.] In a method of recovering residues of beverages in a state fit for consumption, the residue is removed from the storage vessel, cooled, passed through a cooled filter, and mixed with a quantity of the fresh beverage during the passage of the latter to the draw-off tap, in such a manner that the filtrate cannot enter the vessel in which the fresh beverage is stored. The vessel in which the residue is cooled may also serve as a filtering reservoir. The residue is poured into a vessel 1, Fig. 1, which may be of glass and may be surrounded bv ice contained in a vessel 2 mounted so as to be vertically movable in an ice-chest. The residue passes by way of a filter 3 and pipes 4, 5 to the tap 7 of a freshly-tapped cask 8, where it enters a groove 10, Fig. 2, in the tap-plug 11, disposed below the entrance 6 of the draw-off tube from the cask 8, the length of the horizontal portion of the groove corresponding with the extent of turn of the plug. In another form of tap, Fig. 3, the filtrate enters a circumferential groove 13 which communicates with the outlet by means of an aperture 14. The pipe 5 may be cast integrally with the tap.

As shown, the lamp D is fed from a 50-cycle source A1, A2. For starting, the lamp is fed directly through an inductance L the resistance R being shortcircuited by the switch S closing contacts a, b. When the switch is moved to open these contacts and close'the contacts c, d the resistance R passes sufficient current to maintain ionisation in the lamp, the main current being fed through the switching device G. This is rotated at 25 r.p.s., the frame frequency being 25, by a synchronous motor. Brushes B1, B2 and electrically-connected conducting segments G1, G2 are provided and alternate half cycles thereby suppressed, the film being fed in alternate dark periods. With a supply frequency of 100 c.p.s. alternate whole cycles may be suppressed and with a supply frequency of 75 c.p.s. the third, fifth and sixth half in each frame period may be suppressed and the film fed during the fifth and sixth half cycles. Frame frequencies other than 25, e.g. 24, may be employed. The brushes B1, B2, or the motor driving the drum G, are rotatable to adjust the moments of make and break to correspond to zero current.
