Title: Improvements in or relating to liquid fuel fired boilers
IPC: F24H9/18
Filed: 1954-10-06
Abstract: 785,370. Liquid fuel burners. CRICCA, L., and ZAMBRINI, L. M. Oct. 6, 1954, No. 28741/54. Classes 75(1) and 75(3) [Also in Group XII] In an automatically operated oil fired boiler wherein the boiler proper comprises a bell-shaped housing the oil feed to the furnace is controlled by a thermostat located on the housing. The boiler plant shown, Fig. 1, comprises a boiler housing 20 in the interior of which is fixed a burner tube 1, an outlet 21 for combustion gases and a thermostat 15. The latter controls through a rod 27 and a needle valve 14, the oil feed from a tank 6 to a burner tray 3 disposed beneath the burner tube 1. A wick 16 at the edge of the burner tray is fed directly from the tank 6 by a pipe 17. The oil level in the tank is maintained constant by a float valve mechanism 9, 10, 11. At starting volatile fuel is burned on the oil in the burner tray. The flame heats the burner tube 1 and thus causes air from the atmosphere to flow over the burning fuel and assist the combustion of the oil in the tray. When the water in the housing 20 attains a predetermined temperature the thermostat closes the needle valve 14. On drop of water temperature the thermostat opens the needle valve 14 and the oil in the tray 3 is ignited by the wick 16. In a modification, Fig. 3, the burner tube 1 is replaced by a member 33 and the burner tray 34 is formed with a central opening through which an ejector 42 protrudes. An annular water jacket 36, having replenishment means, is disposed above the burner tray 34 such that combustion gases pass through the central passage formed by the jacket. This steam generated in the jacket is conducted to the ejector 42, Fig. 4, where it is employed as the carrier fluid for oil fuel ejection. A fuel feed pipe 5 connects both the ejector and the tray to the tank 6. Additional ejectors may be provided.

Title: Improvements in or relating to alkyd based synthetic resinous products
Inventor: PHILLIPS LESLIE NATHAN
IPC: C08G18/42
Filed: 1951-12-07
Abstract: Polyurethanes are produced by reacting together an alkyl resin modified with an epoxy resin, and an isocyanate with at least two reactive NCO groups.  Epoxy resins are made from epichlorhydrin and a dihydric phenol, e.g. diphenylolpropane or resorcinol.  They may themselves be modified by reaction with other resins, e.g. phenol-, resorcinol-, urea- or melamine - formaldehyde resins. Suitable alkyd resins may for example be prepared as described in Specifications 719,539 or 736,953 or may be based on adipic or pimelic acids, with or without phthalic or maleic anhydride, and ethylene or diethylene glycol, trimethylol propane, glycerol or pentaerythritol.  The alkyd is modified by the epoxy resin by heating, e.g. at 50-300 DEG  C. The isocyanate, preferably m-toluylene diisocyanate, is added preferably in stoichiometrical proportion at room temperature.  It may be dissolved in toluene. In examples: (1) an alkyd from succinic acid, phthalic anhydride, sebacic acid and glycerol is reacted with an epoxy resin and then converted to a stiff foam by mixing with m-toluylene diisocyanate and zinc oxide; (2) an alkyd from sebacic acid and glycerol modified with an epoxy resin is foamed with m-toluylene diisocyanate and zinc oxide; (3) an alkyd from phthalic, succinic, and sebacic acids and glycerol is modified with an epoxy resin and mixed with m-toluylene diisocyanate to form an adhesive.  A solution of the mixture in an ethyl acetate-butyl acetate mixture may be employed as a lacquer.  The nature of the final product can be controlled to some extent by adjustment of the acid number of the modified alkyd resin.  The foamed products which may be produced in situ may be used as core layers of sandwich structures.

An output from the shift pulse generator 14 is also fed to a generator 15 which produces four sequential bit pulses B 1  B 2  B 4  Be Fig. 3 of binary significance. Upon receipt of an output from generator 15 a pulse generator 16 produces six sequential digit pulses D1-D6. Each digit pulse recurs each second and has a duration of 1/6 sec. A four bit output of shift register 19 corresponding to a predetermined digit position, is supplied to the decoder 27 through a one digit time delay means consisting of a parallel inparallel out shift register 26. The decoder has seven outputs A to G connected to respective numeral electrodes of the six digit indicators Figs. 4, 5 (not shown). A common electrode of each indicator is connected to receive a respective one of the sequential digit pulses D1-D6. Either 12 hour or 24 hour system time indication is selectable by a switch 32.

To obtain the desired grain orientation a cast ingot having a columnar grain macrostructure 23 (Figs. 5 and 6) is rolled between rolls 21, 22, the columnar grains running either parallel (Fig. 5) or normal (Fig. 6 and 7) to the rolling direction. In an example a slab cut from a grain oriented ingot is heated to between 700 and 1100‹C and rolled to give a reduction of 90 to 97% into strip which is annealed in dry hydrogen ranging from about 4 hours at 1000‹C. to about ¢-hour at 1200‹C. After cooling the strip is cold rolled to the desired final thickness, e.g. 0.012 inch; after which it is annealed at 1150‹ to 1250‹C. in dry hydrogen and furnace cooled at the rate of about 100C‹. per hour down to 200 ‹C. and then air cooled. The hydrogen anneals reduce the carbon content from 0.04% in the ingot to 0.002% or less in the strip. Specification 870,214 and U.S.A. Specification 2,112,084 are referred to.

Bell pumps.-An air compressor comprises a liquid supply tank permanently connected by a conduit with a vertically movable liquid vessel which is connected with an air compressing plunger either directly or through gearing; the flow of liquid between the tank and vessel effects the compression and is produced by power applied to move the vessel. Fig. 1 shows apparatus wherein a tank 3 communicates through a pipe 1 controlled by a valve k with a vessel 2 with sides extended to form a plunger 4 working in a sealing liquid in a cylinder b, or otherwise making an airtight joint with the cylinder. On opening the valve k at the top of the stroke. the small amount of liquid remaining in the vessel 2 causes it to fall, with a further inflow from the tank 3 until, at the end of the stroke, the compressed air is released through a valve 5. The plunger is raised by power. Fig. 2 shows a modified apparatus in which the vessel 2 is connected with the plunger 4 by gearing 8, 9. In a modification, the vessel 2 may be tapered towards the bottom.
