Title: Improvements in mechanical toys
IPC: A63H1/32
Filed: 1926-03-30
Abstract: 273,393. Wildey, E. M. March 30, 1926. Spinning toys held in the hand during operation; illuminating toys.-A spark-producing toy comprises a ring loosely mounted on the periphery of a disc and means for imparting a friction drive of rotation from one element to the other. As shown, a disc a, adapted to be rotated by the winding and unwinding action of cords k, is provided with a number of rods c of pyrophoric material which are slidable within slots in the rim of the disc and extend into a groove d in a ring b. As the disc rotates, the rods are forced by centrifugal action into engagement with the inner abrasive surface e of the groove d, the resulting friction causing showers of sparks to be produced. The rods may be adjusted by the rotation of a cam f. In a modification, the rods are mounted in slots in the ring and extend into a groove in the disc. In a further modification, the ring is guided on the disc by fixed projections on the disc entering the groove in the ring, thereby allowing the rods a greater range of movement.

IPC: F23L1/02
Filed: 1955-03-24
Abstract: 796,155. Travelling grate stokers. WRAY, J. W. March 24, 1955, No. 8656/55. Class 51(1). A travelling grate stoker has apparatus for improving the ignition of low volatile fuels comprising, mounted between the forward and return runs of the grate, a nozzle for directing a stream of gas into a conduit so as to create an entrainment zone in the vicinity of the entrance of the conduit, the entrainment zone being arranged so as to draw combustion products over fuel on the grate prior to the entry of that fuel into a combustion zone. In the stoker shown, primary combustion air forms the stream of gas and a plurality of nozzles is provided. Between the forward and return runs 1, 2, of the grate is a duct 3 one wall 4 of which is inclined and has a series of nozzles 5 secured to it. The nozzles co-operate with venturi-like conduits 6 and surrounding each nozzle is a zone bounded by part of the wall 4, inclined side walls 7, 8, and a part of a vertical wall 9 in which is formed the entrance to the associated conduit 6. These walls form a hopper having an outlet controlled by a weight-controlled gate 100. The duct 3 is connected through a dampercontrolled conduit 13 to the discharge side of a motor-driven fan 14, the intake side of which is connected through a damper-controlled conduit 17 to an air chamber 16 beneath the grate run 1. Air drawn from the chamber 16 may be mixed with atmospheric air at 19 before being passed to the duct 3. In operation, a suction zone is created below the grate run 1 over the width of the grate in the region of the duct 3, the suction effect drawing back hot gases from the combustion zone of the furnace to thereby dry " green fuel " upon the front part of the grate, the gases drawn back being mixed with the air issuing from the nozzles 5 for return to the combustion zone through the conduits 6. Automatic means for controlling the pressure of air supply to the nozzles 5 may be provided. Such means may comprise a device actuating the dampers controlling air flow in the ducts 13, 17, by being responsive to the temperature of the gases entering the entrainment zones. Particles deposited by the circulating combustion gases on each gate 10 are intermittently and automatically passed to a hopper 20 into which some of the particles which are carried through the conduits 6 are also dropped. Instead of air, each nozzle may be supplied with steam under pressure.

Convention date, March 20, 1934. [Class 7 (iii)] In forming a charge by emulsifying liquid fuel with a small quantity of air and catalyzing the emulsion before the addition thereto of the main air supply, the primary air is supplied in two separate and successive stages. Air introduced through apertures 3 emulsifies fuel sprayed through a nozzle 1 and a small quantity of additional air is introduced through apertures 6, associated with an air inlet 4, to emulsify the fuel further as it passes through apertures 9 in an adjustable plate 8 to an exhaust heated catalyser 10. This comprises tubes lined at the lower end with a copper-nickel alloy and at the upper end with copper or chromed copper. A passage 16 leads the products to a chamber 17 where the heavier particles condense and are drained off and sulphur and acids are removed by a filter 22 comprising iron filings and caustic soda or potash. For normal running, a pipe 20 in the chamber 17 supplies a tube 23 leading to a Venturi 25, secondary air being supplied past a choke valve 28, control of which operates a throttle 29. As shown, a smaller pipe 21 in the chamber 17 supplies a similar idling device 38 but the idling device may have a separate catalyzer and mixing chamber. Interconnected valves 47, 48 control the supply to the induction manifold of either the treated mixture or that from a petrol carburetter 45. Alternatively, the petrol carburetter may connect directly with the chamber 17.

Title: Process and apparatus for the dehydration of a gas
Inventor: REMAN GERRIT HENDRIK
IPC: E21B43/36
Filed: 1967-02-24
Abstract: 1,131,003. Gas dehydration. SHELL INTERNATIONALE RESEARCH MAATSCHAPPIJ N.V. 24 Feb., 1967, No. 8862/67. Heading B1L. Gas from underwater wells is dehydrated by bringing it into contact with a water absorbing liquid (e.g. an alcohol or a polyhydric alcohol) in a section of pipe line, the liquid being changed at least intermittently. This may be accomplished by running two pipes external to the said pipeline one for supply and the other for return whereby the returned water absorbing liquid is regenerated (e.g. by heating) and used to further dry the gas, on shore, before being returned to the pipeline. Another method of returning the water absorbing liquid is by driving it along in front of a solid body that fits the pipeline and is carried along with the gas stream. The section of pipeline used to contain the water-absorbing liquid must be bounded by means to prevent the liquid from extending beyond this section, e.g., by locating the section between two parts of the pipeline that have an upward slope. The gas may merely pass over the liquid in the pipeline, or it may bubble therethrough, or other means, e.g. trays, baffles or atomisers, may be provided for promoting gas-liquid contact.
