Oil gas plant comprises a generator band regenerators a, c, each end of the generator having a fuel inlet b 4  and being connected to an end of one of the regenerators; inlets for gasifying agent from a line n (air, oxygen or mixtures with or without steam) and an outlet j for the product gases are provided at the other end of the regenerators, enabling the flow of gases to be reversed in alternate stages of operation. The outlet gases heat incoming fuel in a heat exchanger l, e.g. to 300‹-380‹C. The fuel may be mixed with steam or gas, e.g. produced in the plant. The gasifying agent may be heated in the regenerator to 1,000‹-1,400‹C. Steam preferably replaces gasifying agent supplied to the first regenerator to purge oxygen therefrom immediately before reversing the flow, and is exclusively supplied thereafter for a short time to the other regenerator. Super-atmospheric pressures, e.g. 5-30 atmospheres may be employed.

Abstract: 1488569 Cooling tower BALCKE-DURR AG 22 May 1975 [2 Nov 1974] 22314/75 Headings F4K and F4S In a tower for air cooling of hot water, there are (a) wet heat transfer elements 3 where the water is sprayed on to surfaces, trickles thereover and is cooled by partly evaporating into air streams 2 and (b) tubular heat transfer elements 4 which can be operated selectively (i) wet as at (a), and/or (ii) dry with the hot water passing through the tubular elements 4 which are externally cooled by the air streams 2. As shown, water to be cooled is supplied through a pipe-line 5. Some is cooled in elements 4 and some on elements 3. The cooled water is collected in a tank 7 and removed through a duct 8. Whether the elements 4 operate wet or dry is regulated by units 6. The tubular hollow elements 4 may be formed of plastics material. The elements 3 may be trickle plates. Fig. 3 shows an arrangement where water to be cooled is supplied at 10 to an element 4 and flows through cavities therein for indirect air-cooling. Thereafter the water can be arranged to pass through stepped sprays of a spraying system 9. Some or all the sprays spray the water on to the element. Evaporative cooling occurs as the water trickles over the element. The tubular hollow elements 4, Fig. 4 (not shown) may be connected such that the water flows therethrough in series. A heat exchange element 4 may comprise panels of tubes in communication with water chambers 12, Fig. 5. Air flows upwards in spaces between the panels of tubes. The spaces are defined by spacers 13 and 14. The tower can be operated fume-free by altering the ratio of wet to dry exchange surfaces.

In forming the article, a base sheet 4 is placed on a die 2 of desired shape, and successive tape layers are built up on sheet 4 by diffusion-bonding tapes 6 side-by-side. The tapes are built up approximately to the desired finished shape and size of article. A cover sheet 14 is then placed over the assembly and edge margins of sheets 4, 14 are welded together to form an assembly which is totally enclosed except for a small hole through which the envelope can be evacuated. After evacuation the assembly is pressed between the dies 2, 16 to consolidate it and diffusion bond the sheath to the body of tapes. Finally, the edges are trimmed. The sheath may be of aluminium alloy, titanium, or stainless steel. The tape is fibrereinforced, having fibres of boron, boron silicon carbide, or silicon carbide embedded in metal which may be a super alloy or one of the metals used for the sheath. The process can be operated under computer control providing for tape supply and advance, bonding and shearing.

Title: Improvements in or relating to liquid fuel admission devices for internal combustionengines
IPC: F02M59/36
Filed: 1924-09-24
Abstract: 248,017. Invernairn (W. Beardmore), Lord, and Chorlton, A. E. L. Sept. 24. 1924. Auxiliary actuating-gear.-A device for effecting the delivery of intermittent fine sprays by the action of a pump and particularly applicable to the injection of liquid fuel into the cylinders of high-speed internal combustion cylinders, comprises a pump which delivers the liquid at a substantial and uniform pressure through an expansion chamber into a delivery passage leading to an automatic sprayer, associated with a reciprocatory plunger in the delivery passage which imparts impulses to the liquid column at an increased pressure sufficient to operate the sprayer, a valve device causing the portions of each delivery stroke of the pump plunger to be ineffective. Fuel flowing along a pipe A is fed by the rotary pump B past an expansion chamber D to a pipe C<1>, leading to a distributing valve M. the liquid being finally fed to the atomizer O operated by the spring-controlled valve O<1>. The arrangements for producing the pressure pulsation sufficient to press back suddenly the valve O<1> and spray a predetermined quantity of liquid fuel into the cylinder comprise a reciprocating plunger pump G of which the part C of the delivery passage constitutes the part of the chamber. The movements of the reciprocating plunger of the pump are communicated to a valve E having reduced portions E<1>, E<2> by way of the two-armed lever J, J eccentrically pivoted at J<2>. In operation, on the compression stroke of the pump G the valve E is initially open, rendering this portion of the stroke ineffective, but when the pump is about the middle of its stroke the valve E is closed and the atomizer O is suddenly opened and is immediately afterwards as suddenly closed owing to the opening of the valve E. A distributing valve M controls the passage leading to the various sprayers. In a modification, the plunger of the reciprocating plunger device is constructed to act as its own valve. In this form, the pump piston works in a casing R having a central portion R' of reduced diameter equal to the diameter of the piston S. When the piston is about the middle of its stroke the plunger passes the restricted portion R<1> and augments the pressure set up by the rotary pump B<1> sufficiently to open the atomizer O which immediately closes when the plunger has passed the restricted portion R<1>.
