Abstract: 769,829. Gases containing hydrogen and carbon monoxide. FOSTER WHEELER, Ltd. June 2, 1955 [June 2, 1954], No. 15846/55. Class 55 (1). Apparatus for the production of a gas containing hydrogen and carbon monoxide comprises a reactor 20 wherein a suspension of a particulate solid carbonaceous fuel in steam is gasified with oxygen, a waste-heat boiler 86 through which by line 30 the gaseous products from the reactor are led and a preheater 130 wherein a mixture of steam and solid fuel is preheated by means of the gaseous products after they have left the boiler. As shown, the gaseous products leave the boiler 86 by line 99 passing first to a steam superheater 101 and thence by line 117 to the preheater 130 which they leave by line 149. The reactor 20 has an annular boiler, the steam drum 33 of which is connected by a line 36 to the outlet line 30 for gaseous products to equalize the pressure on the inner shell of the boiler. The reactor terminates at its lower end in a restricted throat where gaseous products are sprayed with water from sprays 28. Clinker collects in the vessel 27 and sinks to the bottom of the water contained therein. The clinker is ground between two rollers and passes through valves 46 and 47 into a hopper 45 from which it is discharged. The waste-heat boiler 86 and the superheater 101 comprise a tubular system for heat exchange between the hot gaseous products and water or steam and their outer shells are formed as annular boilers. The preheater 130 also has a tubular system for heat exchange. The preheater 130 and the superheater 101 have bellows type expansion seals 144 and 114 respectively. Pulverized coal is fed under gravity from a storage bin 120 through conduits 121 and controlled by gate valves 122 and thence by line 123 and lock valve 125 into a lock hopper 124. The hopper 124 is connected through a lock valve (not shown) with a pressure hopper 127 and the coal is discharged therefrom by a coal feeder 128 into line 129 to be picked up by superheated steam in line 118. The mixture of coal and steam is preheated and flows through conduits 21 into the reactor 20 where it is reacted with oxygen.

Abstract: 553,803. Controlling variable delivery pumps. SHAW & SONS (SALFORD), Ltd., J., and SHAW, J. B. Dec. 19, 1941, No. 16409. [Class 135] A control mechanism for variable delivery pumps wherein a main pump is brought into operation by pressure generated by a pilot pump has a bye-pass valve arranged on the delivery side of the pilot pump which is held open when the control member, actuated either manually or automatically under the influence of the load on the delivery side, is placed in its neutral position to prevent the pilot pump building up an operating pressure. In the form shown in the Figures the main pump is regulated by a reciprocating member 4 actuated by a double-acting piston housed in a cylinder 5. The two sides of the cylinder are connected by pipes 13a, 13b to a reversible pilot pump 3. The control member 7 of this pump is actuated by a floating lever 6 pivoted at 4a to the member 4 and to a link 8 pivoted to a hand-lever 9. The conduit 13a is connected by a pipe 21 to a port 20 on the by-pass valve 15 mounted on a support 16. A piston valve 17 controlling the connection between the port 20 and a vent pipe 20a is actuated by a link 18 connected to a crank arm 19 coupled to the hand lever 9. The two sides of the control cylinder are fitted with relief valves 14. The hand-lever is coupled by a link 12a to a hydraulic telemotor transmitter 12. Where creeping in either direction from an intermediate neutral position is to be avoided a bye-pass valve is provided in both the pipes leading from the pilot pump.

[Also in Group XVII] Jointing by stamping.-A supply roll of sheet material wound on a core 28, e.g. a toilet roll 25, has embedded within the core at a position intermediate the ends a ring 26 adapted to form a circular track for engagement with an upright spindle to rotatably support the roll. The ring is secured to the paper core by applying axial pressure to it from opposite sides to expand it peripherally and embed its outer edge in the core. A sheet-metal strip 90 of W-cross section is slitted at 93 and shaped at its ends to interfit at 91, 92 when the strip is bent round to form the split ring 26, Fig. 9. The roll 25 with its paper core 28 is placed over a mandrel 100, the ring 26 placed within the core upon the surface 102 of the mandrel and a die 103 moved downwardly to compress and expand the ring, the slits 103 opening out to form a serrated periphery which is embedded in the core. The upper and lower flanges of the ring form tracks 37 either of which can engage retractable balls on a downwardly projecting spindle to support a stack of rolls with the lowermost roll exposed, as described in Specification 747,176, [Group XVII]. When the lowermost roll is exhausted leaving the core 28, the user strips the core from the lower end of the spindle, the split ring . distorting to clear the supporting balls and usually coming away with the core, allowing the upper roll to fall until its ring rests on the balls. If the ring is not removed, the falling upper roll strikes it and causes it to expand and be released from the balls. If the ring is unsplit it can be released by an attendant retracting the balls.
