Title: Improvements relating to frozen-food display cases
Inventor: WILLIAMS CHARLES EDWARD
IPC: A47F3/04
Filed: 1960-11-19
Abstract: 914,319. Refrigerators. GENERAL MOTORS Ltd. Oct. 18, 1961 [Nov. 19, 1960], No. 39859/60. Class 29. A frozen food display case has installed in its wall two refrigerant evaporators which respectively form part of two separate refrigeration systems, one evaporator being in the inner part of the wall. As shown, the display case comprises an open-topped cabinet 1 having a double-walled front 2, bottom 3, and rear 4, and a top forward extension 5 of the rear wall, carrying an electric light 15. The end walls may also be double. The top portion of the front wall 2 is formed of spaced glass panels 8. A low temperature evaporator tube 7 forming part of a refrigeration system having also a compressor 19 and a condenser 20, is secured to the outer face of the innermost metal liner c of the cabinet. A higher temperature evaporator 9 is located in the air space d between the inner and outer cabinet walls and forms part of the second refrigeration system having a compressor 23 and a condenser 24. A fan 10 circulates air through the space d, over the evaporator 9, to emerge from the top overhang 5 and form a cold air curtain across the access opening 6. A simple ball-float type drain valve 16 in the bottom 3 of the casing allows " defront " water to drain away.

Patent GB-1202245-A (GB)
Title: Improvements in or relating to apparatus for regulating free piston gas generators
IPC: F02B71/00
Filed: 1967-09-04
Abstract: 1,202,245. Fluid-pressure servomotor systems. SOC. INDUSTRIELLE GENERALE DE MECANIQUE APPLIQUEE. Sept.4, 1967 [Sept.21, 1966], No.40379/67. Heading G3P. [Also in Division F1] The turbine may drive a regulator (not shown) which causes variation as a function of the turbine load of the pressure of a fluid, such as oil, in  the conduit 9. The modulation of the pressure in the conduit 9 may be obtained by a control device for adjustment by the operator or by a watt meter regulator connected to the terminals of an alternator driven by the turbine or by a pressure regulator or flow regulator of a compressor or of a pump driven by the turbine. The modulated oil pressure is transmitted to the regulating device D and acts on the valve 7. Fig.1 (not shown) in such a manner that at low loads a larger or smaller part of the gas delivered by the free piston gas generator can escape through the exhaust conduit. For a medium load and for higher loads the valve 7 completely closes the exhaust conduit 8 so that all the gas produced by the gas generator reaches the turbine. A practically constant quantity of control liquid is made to enter the enclosure 14a during each oscillation of the free pistons and a certain quantity is evacuated in the period during which the free pistons are located in the immediate region of their outer dead point, this certain quantity depending on a control member whose position is a function of the factor which determines the desired outer dead point and on a control member whose position is a function of the momentary outer dead point. When the hollow slider 15 is displaced towards the top under the influence of the factor which determines the outer dead point thus displacement has, as long as the outer dead point has not undergone a corresponding modification, the effect of reducing the section of the opening through which the control liquid can escape from the enclosure 14a and of reducing at the same time the duration during which this opening is unblocked. Consequently the quantity of control liquid which enters the enclosure 14a, is greater than the quantity which leaves this enclosure which causes the piston 11 to move upwards in its cylinder 14 to displace the rack 10 in the sense to increase the injection of fuel. This increase in the injection of fuel causes an outward displacement of the outer dead point which causes the slider 17 to move further upwards inside the slider 15 until the moment when the section of the opening through which a part of the control liquid escapes from the enclosure 14a has reached its previous value at which there is equality between the quantity of control liquid which enters the enclosure 14a and the quantity which leaves this enclosure during one complete oscillation of the free pistons.

Abstract: 1361261 Purifying IC engine exhaust gases; silencing ALFA ROMEO SpA 6 Sept 1971 [22 Sept 1970] 41545/71 Heading F1B [Also in Division F2] The flow of exhaust gases from an engine 1 through a main exhaust duct 9, 13 is controlled by a valve 14 in the duct downstream of a silencer 11. The valve 14 is closed in the lower power output range of the engine and/or if the temperature sensed by an element 23 in a supplementary exhaust duct 25, 26, 27, 28 is below a selected value so that the exhaust gases pass through the afterburner 27. The valve 14 is open in higher engine output range and/or if the sensed temperature is above a selected value. A diaphragm 18 or a piston, actuating the valve 14, is subjected to the intake manifold vacuum or atmosphere pressure under the control of a valve 22 operated by the element 23. The afterburner 27, e.g. a thermal or catalytic reactor, the supplementary manifold 26, the pipes 25 and the main manifold 9 may be insulated by a still air chamber defined by a sheet metal cover. The upstream portions of the supplementary duct may be formed from double-walled stainless steel sheet. A pump may supply the afterburner 27 or the supplementary duct upstream of the afterburner with combustion air. The pipe 28 may connect with the pipe 13 downstream of the valve 14 and upstream of the silencer 24. A butterfly valve (40), Fig. 3 (not shown), may be provided in the pipe 28 to be operated with the valve 14, the butterfly valve being closed when the valve 14 is open and vice versa.

Title: Process and apparatus for the manufacture of alkali metal phosphates
IPC: C01B25/30
Filed: 1960-12-02
Abstract: Alkali metal phosphates are manufactured from alkali metal chlorides, suspended in air and/or O2, phosphorus, in the form of a flame, and oxygen, with or without water, by feeding the reactants into a zone parallel to and concentric with each other, whereby the alkali metal chloride is atomized in the hottest interior point of the phosphorus flame produced by reacting molten phosphorus with air and/or O2 using 90-5001.  O2/100g. P, the oxygen, when the reaction is proceeding without the addition of water, being fed in at least such amount as to ensure oxidation of the chloride ion to free chlorine.  The reaction products are discharged as a hot melt which may be cooled and ground and dissolved in water or unsaturated aqueous phosphate solution to give crystalline phosphate, e.g. tri-, pyro- or orthophosphates.  The molar ratio of P2O5 to alkali metal oxide may be 1:1-2.  Burner 5 in Fig. 1 is a multi-component mixing nozzle comprising four tubes fed by NaCl suspended in p  O2 at 1, molten P at 2, O2 at 3 and steam may be at 4. Burner 5 is placed central in tower 6, the inner walls of which are cooled by air or water thereby forming a protective layer of reaction product on the walls.  The melt formed is discharged through line 7 to a cooling roll 8 or through line 9 to a vessel 10, where it may be dissolved <PICT:0939363/III/1> in water with stirring.  The exhaust gas from tower 6 is passed through 11 to absorption tower 12 where it is sprayed with conc. phosphoric acid, recycled by rotary pump 14 from collecting vessel 13.  Gas, freed from alkali metal phosphate and/or P2O5, is led through 16 to a unit 18 for HCl production, alternatively if H2O was used in the reaction, the exhaust gas is led through 17.  The HCl is absorbed in 19 by aqueous HCl and the residual gases are removed to chimney 22.  If the amount of exhaust gas produced is small and if HCl is not required to be isolated, the exhaust gas can be passed through a tower filled with lime only.
