Title: Improvements in or relating to machines for feeding mold charges of molten glass
IPC: C03B7/10
Filed: 1928-12-05
Abstract: 318,063. Wade, H., (Miller Inc., W. J.). Dec. 5, 1928. Delivering molten metal.-A feeder of tlte reciprocating-plunger type has a cutting, device which comprises reciprocating shear blades, and the mechanism for reciprocating the blades comprises a driving-link which also closes the shears at a predetermined position relative to the outlet. The feeder, shown in plan in Fig. 2. is constructed as described in Specification 316,837 and comprises a driving-shaft 63 which reciprocates and rotates the plunger 5. A cam 133, mounted on one end of the driving-shaft 63, oscillates a horizontal lever 128 on a pivot 130, the lever being kept in contact with the cam by means of a spring 136. The free end of the lever is pivoted to a link 152 which slides through a casting 138 clamped to the frame of the feeder. Two parallel rods 143 also slide through the casting and their front ends are connected by a crosshead 144, Fig. 4, on which the shear blades 145 are pivoted. A second crosshead 146 slides along the rods 143 and is urged away from the crosshead 144 by springs 147 coiled on the rods. A forked lever 148 secured to the crosshead 146 carries pins 149 which work in angular slots 150 in the shear blades 145, so that the blades are closed or opened by movement of the crosshead 146 to or from the crosshead 144. The front end of the link 152 is pivoted to the crosshead 146, and limiting nuts 151 are screwed on to the free ends of the rods 143. In operation, the inward movement of the lever 128 carries the crossbeads 144, 146, and therefore the shears 145, towards the outlet orifice 5. When the nuts 151 engage the casting 138, continued movement of the lever 128, and therefore the crosshead 146 and the lever 148, causes the blades 145 to close. The position of the nuts 151 is so adjusted that the blades close beneath the aperture 4. The reverse movement of the lever 128 first opens the blades and then withdraws them from beneath the outlet.

Abstract: 408,399. Rotary pumps. SAVERY & CO., Ltd., T. A., and RODAWAY, E. 0., Bracebridge Street, Birmingham. Dec. 19, 1932, No. 35920. [Class 110 (ii).] A rotary pump ot the geared vane type in which impellers k slide around an annular chamber as described in Specification 352,268, has means comprising an eccentric rotatable bush d to regulate the impeller deliveries through altering the relative eccentricity of the driving shaft f and plate g, and the annular working chamber j. The bush d may be turned by a tool entering a slot i. The plate g has pins q and rollers r operating in radial slots h, the pins driving impellers k. Segmental grooves m, n, in the casing b, connect with the inlet and outlet passages respectively. In a modification, Fig. 6, an eccentric bush u has an extension t forming the outer periphery of the working chamber. A handle v is provided to rotate the bush and so alter the eccentricity of the working chamber. The impellers k run on a hardened ring 10. To prevent the rotation of the part x, which contains the inlet and outlet passages, a collar 2 is affixed to the spindle w so that when the handle and bush u are turned about the spindle, the movement of the collar 2 and the spindle is restricted by the lug 4, Fig. 8. Inlet and outlet passages o are provided, which connect with arcuate slots in the part x. The impellers and the annular chamber may be separately adjustable.

Abstract: 1398858 Pyrolysis of waste materials OCCIDENTAL PETROLEUM CORP 2 Aug 1972 36073/72 Heading C1K [Also in Division C5] Waste materials containing organic solids are entrained in a turbulent stream of hot particulate char and carrier gas and passed into a pyrolysis zone for an average residence period of up to 10 seconds during which the waste materials are heated to 150-1400‹ C. by the char to produce volatile organic chemical and fuel values. A feed 2, such as municipal waste, manure, sewage sludge, tyres, oil processing waste, agricultural waste, industrial waste, tree bark, sawdust and rice hulls, is dried at 16 with air 10 and recycle gas 97. The dried waste is entrained in a stream of hot recycle gas 99 and hot recycle char 60 and passed through the pyrolysis reactor 32. The pyrolysis product is separated into a char stream 38, which is in part removed as char product 68 and in part recycled as hot char after reheating by partial combustion at 48, and a gaseous stream 76 which is separated into a gaseous product 93 an " oil " product 102 and an aqueous material 94. Metal and glass can be removed from the comminuted waste material before the pyrolysis and the feed to the pyrolysis zone can contain lime or iron oxide to assist desulphurization.

Title: Rotary screen printing machine
IPC: B41F15/44
Filed: 1976-09-02
Abstract: 1515598 Printing machines STORK BRABANT BV 2 Sept 1976 [3 Sept 1975] 36456/76 Heading B6C The specification is concerned with the problem of maintaining uniform printing across the width of a rotary screen stencil, non-uniformity being said to arise due to deformation of the stencil leading to a non-uniform squeegee angle. This can be solved by making the end rings of the screen with a flexible portion to allow the ends of the stencil to depart from circularity, as does the centre. Alternatively, the squeegee and/or its support may be constructed so as to be more deformable adjacent the ends of the stencil than in the central area.

Abstract: 522,909. Steroid com pounds. PARKE, DAVIS & CO. Dec. 20, 1938, No. 37061. Convention date, Dec. 23, 1937. [Class 2 (iii)] Nuclear saturated, hydroxy steroid compounds with an unsaturated hydrocarbon side chain are prepared from 3-keto steroids having an unsaturated side chain and also a nuclear double bond in the α-# position with respect to the keto group by treatment with nacent hydrogen. The reducing medium is preferably obtained by the reaction of an alkali metal and an alcohol. Steroid compounds mentioned as starting materials for the present invention include the 3-keto derivatives of stigmasterol, ergosterol, and fucosterol. The hydroxysteroids prepared by the reduction process of the invention may be converted into their equivalent derivatives capable on hydrolysis of being converted into the corresponding hydroxy compounds, such as by esterification, etherification or halogenation. Agents mentioned for this purpose include anhydride, phosphorus halides and thionyl halides, and etherifying agents such as the action of an alcohol in the presence of sulphuric acid. In an example, stigmastenone prepared by treatment of stigmasterol with precipitated copper in a retort at 180‹-275‹ C. is reduced by the action of metallic sodium in amyl alcohol solution. The reduction product is converted into the corresponding half succinic ester by treatment with succinic anhydride, and extracted with alkali to give 5:6-dihydrostigmasterol. This is purified with digitonine with which it forms an insoluble compound. The corresponding diacetate is formed by refluxing with acetic anhydride.

The arrangement is such that rotation of the bushing 27 by turning the control knob anticlockwise to an ignition position causes the pilot valve to open and the armature plate to be urged against the electromagnet, the torsion spring maintaining the bushing 27 in this position if the electromagnet is excited by the presence of a pilot flame, axial displacement of the control knob causes the main valve to open, and subsequent further rotation of the knob causes the projections 33 to engage the immovable cam track. If the electromagnet is not excited the stop lugs 273 become disengaged from the fork 28 and the main valve is closed. The disc 26 has a lug (262), see Fig. 4 (not shown), with a sloping surface midway between the two lugs 261. The stop lugs 273 are located in the bushing at a distance from its end which together with the axial displacement of the bushing is equal to at least the distance through which the closure member of the main valve is displaceable. The immovable cam track is formed by two diametrically opposed tracks (321, 322), see Fig. 4 (not shown), which have inclined surfaces facing the main gas valve. In Fig. 1 (not shown) are disclosed a gas flow regulator (12), a safety valve having a closure member (123), and a water shortage safety cut-out device (not shown).
