Title: Improvements in or relating to a process for the preservation of liquid or semi-solid foodstuffs
IPC: A23L3/3409
Filed: 1952-09-30
Abstract: Liquid or semi-solid foods, particularly dairy products such as milk, are preserved by sealing with an equal volume of oxygen and raising the temperature to at least 68 DEG C. while agitating the food for half an hour.  The food is placed in a pressure container sealable by a gas-tight valve, enclosed in an atmosphere of oxygen at a pressure of at least four atmospheres, the temperature is raised and the food agitated, and thereafter the pressure of oxygen in the container is maintained at a minimum of 4 atmospheres until the food is required. Specification 721,277 is referred to.

Abstract: 381,684. Centrifugal pumps. TRIGGS, W. W., 57, Lincoln's Inn Fields, London.- (Nash Engineering Co. ; South Norwalk, Connecticut, U.S.A.) Sept. 3, 1931, No. 24786. [Class 110 (i).] In a vacuum steam-heating system the exhaust is connected to a closed separating tank arranged below a water pump for returning the condensate to the boiler and an air pump for maintaining the vacuum, the air pump being adapted to prime the water pump. Steam is supplied by the boiler B to radiators R which discharge into a closed tank S. A centrifugal water pump C, and an air pump N of the hydroturbine type are driven by an electric motor M and mounted above the tank S. If the tank S contains water above the end of the pipe 10, air in that pipe is exhausted by the pump N through passages 13, tank 15 and pipe 18, and water is drawn through pipe 10 to prime the water pump C. Any air in the pump C passes through orifice 21 and passage 14 to tank 15. Water for sealing the air pump may be supplied through pipe 27 controlled by a solenoid valve 26 opened automatically when the pump motor M is started. The water is discharged with the air through pipe 19. Alternatively, water may be drawn by the air pump from the tank S through pipe 30. Discharged water may be separated in the tank 24 and returned to the tank S. The tank 15 may be provided with a float-valve 20 to admit air on a rise in water level therein.

Abstract: 840,970. Liquid-ring pumps and motors. INSTITUT FUR SCHIENENFAHRZEUGE Aug. 20, 1956, No. 25449/56. Classes 110 (1) and 110 (2). An internal-combustion engine comprises a water vessel adapted on rotation to produce a water ring in the vessel, a rotor eccentrically rotatably mounted in the water-ring on a rotatable crank, the crank being divided into a compression compartment and an expansion compartment, a combustion chamber in which liquid or pulverized solid fuel is burnt with air which has been compressed by rotation of the rotor in the water ring, means for conveying the combustion gases to the expansion compartment and thence to the rotor to cause the latter to rotate, and a driving-connection between the rotor and an output shaft. Figs. 3 and 4 show an I.C. engine comprising a rotor 3 journalled on a cranked member 4 and co-operating with a water-ring 2. The rotor 3 is divided into a pump compartment and a motor compartment. The pump compartment draws in air at 8 and delivers compressed air by way of a space 20 and a central duct 44 to a chamber 21 in which it is mixed with coal dust or oil. The mixture is burnt in a chamber 22, and the combustion gases are cleaned by centrifugal action as they pass over a guide 31, ash, water and other impurities being deposited in a water ring 30. The combustion gases enter the motor compartment of the rotor 3 to drive the latter, the drive being transmitted through a coupler 24 and an articulated shaft 25 to an output shaft 28. The cranked member 4 is fixed to the rotary casing 1 so as to be rotated with it by the drag of the rotating water ring 2. The rotor 3 comprises steel tubes which float on the water ring to reduce bearing pressures. In the I.C. engine shown in Fig. 5, the cranked member 4 is keyed at 42 to an outer rotating casing 33, the latter, the inner rotary casing 1 and the rotor 3 being connected together by gearing (not shown) so as to rotate at different speeds. Liquid fuel enters the cranked member 4 through a water-cooled pipe 36 and is sprayed through an annular nozzle 43 into a combustion chamber 35, where it burns with air supplied by the compressor compartment 34. The exhaust gases from the motor compartment 38 pass into the atmosphere at 39. A liquid-ring pump or motor, not forming part of the invention but incorporating gearing which can be used in the engine shown in Fig. 5, comprises gearing 5 connecting the cranked member 4 and the rotary casing 1 so that they rotate in the same direction at 3000 r.p.m. and 4000 r.p.m. respectively. The rotor 3 is rotated at 1500 r.p.m. relative to the cranked member 4 by means of a planet gear 6 engaging an internal gear 7 carried by the rotary casing 1 and therefore gyrates at an absolute speed of 4500 r.p.m.
