Abstract: 454,015. Removing valves. BRUSH ELECTRICAL ENGINEERING CO., Ltd., and SENIOR, G., Falcon Works, Loughborough, Leicestershire. Feb. 22, 1935, No. 5665. [Classes 7 (iii) and 7 (vi)] In a multicylinder engine, in order that repairs or adjustments may be effected, provision is made for the temporary removal of a valve and its seating, or the liquid-fuel admission device, from one cylinder while the engine continues to run on the other cylinders. In a Diesel engine the inlet and exhaust valves 10, 11, of a particular cylinder are held off their seats by cams 32, rotated on a shaft 30 to operate on rockers 16, 17, and the exhaust port is isolated from the rest of the exhaust system by closing a valve in the pipe. The compression is thus eliminated and the exhaust valve and seating may be removed by releasing a clamping screw 37, screwing the ball end 21 into the push rod 18, dismantling the rocker 20, and disconnecting the cooling water connections. The liquid fuel injection device may also be removed after it has been rendered inoperative.

Title: A process for the production of combustible gases from liquid or gaseous fuels
IPC: C01B3/36
Filed: 1951-03-12
Abstract: 716,710. Oil gas; cracking gaseous mixtures. KOPPERS GES., H. March 12, 1951 [March 15, 1950; Aug. 31, 1950; Feb. 27, 1951], No. 5907/51. Class 55 (2) In a process for the production of gas having a high content of carbon monoxide and hydrogen which may be used as town's gas or for synthesis purposes, liquid fue's such as mineral oils or tar or gaseous hydrocarbons are reacted or reformed with preheated steam and oxygen in a regenerator system operating with alternating direction of flow. The apparatus consists of two preheating regenerators 1 and 2 connected by ducts 16 to a reaction heat regenerator 3. Combustion chambers 4 and 5, into which heating fuel may be atomized through nozzles 6 and 7, are provided at the tops of regenerators 1 and 2 respectively. Regenerator 3 is divided by a mid-partition 17 into two vertical compartments into which gasmaking oil may be atomized from nozzles 8 and 9. In operation, steam and oxygen are admitted at 12 into regenerator 1, which has been heated during a previous cycle, and flow into regenerator 3. into which oil is injected through nozzle 9. The oil vaporizes and passes with the steam and oxygen through the regenerator wherein it is cracked and reacts with the steam and oxygen to form permanent gases. The gases pass through regenerator 2 which abstracts part of their heat and discharge to storage at 15. When regenerator 1 has cooled to below gas-making temperature, the " run " is stopped and a heating period commenced, air being admitted to regenerator 1 at 13 and liquid fuel at 6, the resulting combustion gases heating regenerators 3 and 2 and discharging at 14. The " run now takes place in the opposite direction, steam and oxygen being admitted to regenerator 2 at 12 and oil at 8, the cycle being completed by a heating period with gas flow in the same direction.

Abstract: 1,189,101. Centrifugal pumps and axial-flow fans; turbines. DELANEY GALLAY Ltd. May 5, 1967 [Feb.10, 1966], No.5961/66. Headings F1C and F1T. [Also in Division F4] A rotary heat exchanger comprises tubular blades 2 extending radially between a hollow hub 4 and an annular tank 6 secured to the ends of the blades, the blades being twisted about their central axis to reduce their inlet angle as their radius increases so that the perpendicular distance between adjacent surfaces of neighbouring blades (distance a, Figs. 3 and 4) remains substantially constant at all radii. In use, engine coolant water circulates through the blades and is cooled by air passing over the blades, the heat exchanger serving also as a fan or turbine, and as a water pump. As shown, the water passes into the hub 4 through a hollow shaft 8, flows radially outwardly through the blades 2 to the tank 6 and returns to the hub by way of tubes 12. The tubes 12 are angularly spaced by a distance greater than that of the blades 2 which are of narrow elongate cross-section. Each blade may comprise a single tube or alternatively a number of tubes secured edge to edge. The space between adjacent blades may contain secondary heating surface in the form of gauze or corrugated metal. The warm out flowing air may be directed to the vehicle space and this flow may be assisted by a shroud mounted around the heat exchanger and by guide vanes adapted to straighten the air flow.

Abstract: 608,559. Distending cartons. ROSE, A. G., PAGE, J., and ROSE BROS. (GAINSBOROUGH), Ltd. Feb. 26, 1946, No. 6045. [Class 94(i)] In a carton feeding and opening apparatus of the general construction set forth in Specification 485,468, at least a substantial portion of the endwise movement of the transfer blades into and out of the cartons is effected during movement of the blades round their closed path. The claws on the chains 24, which engage the rollers 21 on the blades 13, are extended to form transverse arcuate guides 23. The shaft 17 and the chains 24 are driven by separate Geneva wheels 18, 28 from a common crank wheel 29 rotated from a main shaft 31 through gearing 32. The wheel 29 carries four rollers 38 and four rollers 39 to engage the wheels 18, 28 respectively, and the rollers are disposed so that one enters a slot as the preceding roller leaves a slot, so that the period of rest is momentary. The wheels 18, 28 are out of phase so that the chains are at rest when the shaft has its maximum velocity, and vice versa. The shaft is at rest when a roller 21 is at the middle of each guide 23. The upper and lower guides 22, 22<1> are each shaped with spiral guiding surfaces 36 so that the rollers 21 start vertical movement before entering the guides 23, and the surfaces are arranged so that the vertical velocity of a roller as it enters a guide 23 is equal to that of the guide. The rollers 21 are freely mounted and comprise inner and outer metal sleeves and an intermediate body portion of rubber.

Abstract: 1,018,623. Circuit assemblies. GENERAL ELECTRIC CO. Ltd., and P. A. BARNET. Feb. 15, 1963 [Feb. 16, 1962], No. 6060/62. Heading H1R. In an assembly of circuit modules 2, Fig. I, which may be of the kind described in Specification 1,018,621, the modules are mounted in rows on a plate 1, passages being left between the rows for a coolant such as air. The air may pass unrestrictedly through a channel, as through channel 3, or it may be diverted, as by an obstruction 9 in channel 8, towards modules generating a comparatively large amount of heat. Where modules generate little heat, the quantity of air in a channel, such as 5, may be limited by an obstruction 6 having narrow bore orifices. The channels may be arranged in meander-shaped series fashion. Fig. 3 shows module mounting plates 23-30 defining channels 32-38. To provide additional cooling in region 39, air is diverted from channels 33, 34, 36, 37 into channels 35 by means of obstructions 40, each with a narrow bore, and orifices 41 in plates 25-28. Beyond region 39, the air is returned to its original channels by means of an obstruction 42 and orifices 43. Additional cooling of a particular module may be effected by the provision of cooling fins which may be disposed in one or more channels. Moreover, a cold plate having tubes through which coolant is passed may be interposed between two adjacent module mounting plates. In order to pass cooling liquid through the assembly channels, the latter may be lined with impermeable material such as varnish, synthetic rubber, or adhesive-backed plastic; or plastic pipes or sleeves may be provided in the channels.
