Patent GB-355913-A (GB)
Title: Whipping cream preparation
IPC: A23C13/14
Filed: 1930-07-30
Abstract: A preserved whippable cream is obtained by separating from whole milk a cream containing a high percentage of butter fat, adding thereto a small proportion, e.g. about 1 per cent, of sodium caseinate, and then adding a small quantity of whole milk or of the skimmed milk obtained in the separation to reduce the fat content to about 40 per cent.  The mixture is pasteurized, e.g. by heating at 142-145 DEG  F. for 30 minutes, and homogenized using a pressure not exceeding 750 lbs. per sq. in.  The product may next be introduced into containers, sealed and sterilized by heating at 242-245 DEG  F. or over for 15 minutes.  The whipping properties are improved by chilling the product before the containers are opened.

Abstract: 1,131,746. Regulating fluid-flow. CORNING GLASS WORKS. May 24,1966 [May 24, 1965], No.23058/66, Heading G3H. The flow of liquid material from a reservoir 13 to an outlet 29 of a tube 15 is controlled by fluidpressure in a bell member 19. Flow from the reservoir to the tube takes place through a restricted passage and the fluid-pressure in the bell controls the quantity flowing to the tube 15 which is restricted. As shown, the tube may extend above the bottom of the reservoir and the bell extend over the top of the tube. Alternatively, the bell may be just above the top of the tube or the tube may lead from at the bottom of the tank. In a further modification, the tube is above the level of liquid and suction is applied to the bell.

Title: Improvements in liquid fuel burners
IPC: F23D11/24

Abstract: 960,056. Spray burners. ENTREPRISE GENERALE DE CHAUFFAGE INDUSTRIEL PILLARD FRERES & CIE S.A. June 15, 1962 [Aug. 4, 1961], No. 23131/62. Heading F4T. In a return flow liquid fuel burner 5, 6, 7 the atomizing nozzle is surrounded by an annular passage 4 arranged to direct a centripetal planar stream of air or steam against the base of, and normal to the axis of the jet of atomized fuel, to stabilize the divergence of the jet. In operation, the air is supplied under constant pressure to a chamber 1, passes through holes 2 into an auxiliary chamber 3 and then issues from the annular passage 4. The action of the air or steam is negligible at relatively high liquid fuel output rates when the natural divergence of the atomized jet is relatively small but has its greatest effect at relatively low fuel output rates when the divergence is relatively large. Further jets of air may be provided downstream of the annular passage and inclined to the axis of the nozzle.

[Class 110 (iii)] [Also in Groups XXVII, and XXXIII] In a power plant an engine crankshaft drives one of two coaxial and oppositely rotating propellers C, C<1> and a charging compressor D, and an exhaust actuated turbine E drives the other propeller and an axial flow compressor H supplying charging air to the compressor D. Gearing between the engine crankshaft, the turbine shaft and their respective propellers, which may have variable pitch, is associated in one gear box at the end of the engine. The exhaust may be combined with gas produced' by combustion of fuel in a chamber L, combustion air being taken from the compressor D. Alternatively, air may be added to the exhaust gas which is by-passed from the. combustion chamber L as shown. The compressor H may be a single or multi-stage compressor and the turbine E may have several stages each of which functions as a separate turbine. Alternatively, the gases may pass through the stages in series. The turbine H may be adjacent the gear box, which then contains gearing between the turbine shaft and both the propeller shaft and a shaft leading back to the compressor H. A twin crankshaft engine is shown. If the engine has a single crankshaft a shaft parallel thereto transmits power from the turbine to the second propeller.
