Patent GB-1349576-A (GB)
Title: Refrigerating systems
IPC: F25B11/02
Filed: 1971-04-19
Abstract: 1349576 Refrigerating BRAYTON CYCLE IMPROVEMENT ASSOCIATES 19 April 1971 [5 May 1970] 26397/71 Heading F4H In the refrigeration system as shown, air enters an air cooler, is cooled and passes to a compressor and a recuperator where the air is heated by heat exchange with the exhaust from the Brayton cycle expander and passes into a conventional Brayton cycle combustion chamber. In this chamber fuel is burned and the temperature of the compressed air is raised further, before passing via the expander and recuperator, to and through a refrigerant heater in which pump 2 keeps the refrigerant liquid at a sufficient pressure so that it does not boil. The hot refrigerant liquid flows to an insulated hot storage tank 1. From time to time valve 4 is opened and a batch of hot liquid is transferred from 1 to hot flash tank 3 where it flashes at decreasing temperatures and pressures until it reaches a minimum temperature and pressure. Valve 10 then is opened, the remaining unvapourized liquid flowing into tank 11. Three refrigerant expanders 7, 8, 9 drive corresponding refrigeration compressors 21, 22, and 23. At the start, the temperature and pressure in hot flash tank 3 is at a maximum and the flash vapour passes through expanders 7, 8, 9 in series. At the same time, the pressure and temperature in a cold flash tank 30 is at a maximum, and the load on compressors 21, 22, 23 is at a minimum, and they thereby are operated in parallel. The load on compressors 21, 22, 23 increases as the temperature and pressure in tank 30 drops. When expanders 7, 8, 9 can no longer produce sufficient power to drive the compressors, valves 17, 19, 20, 26 are closed. This has the effect of cutting off expander 9 and compressor 21, and expanders 7 and 8 in series drive compressors 22, 23 in parallel. As the pressure and temperature in tanks 3 and 30 drop still further, valves 13, 15 are opened and valve 14 closed. Now expanders 7, 8 in parallel drive compressors 22, 23 in parallel. As the temperature and pressure drop in stages, expanders 7, 8 in parallel drive two compressors 22, 23 in series; then three expanders 7, 8, 9 operate in parallel to drive the three compressors in series. During the operation, all the exhaust vapours flow to a condenser 34 and to storage tank 11. When the expanders can no longer drive the compressors, valve 10 is opened, and unvapourized liquid in tank 3 enters into tank 11. Unvapourized cold liquid in tank 30 is discharged into storage tank 31, a pump 32 pumping the cold refrigerant liquid through the air cooler and into storage tank 11. Valves 10, 35 now are closed and valves 4, 6 are opened. A new batch of refrigerant liquid from tank 1 thus is introduced into tank 3 and a new batch of ambient temperature liquid is thus introduced into tank 30. The refrigeration cycle is then repeated. The system is self-regulating.

Abstract: 671,820. Crystalline dextrose. WALLERSTEIN CO., Inc. Oct. 12, 1948 [Oct. 13, 1947], No. 26528/48. Class 127. In making crystalline dextrose an aqueous dispersion of starch or converted starch is hydrolysed by adding at least 1/K part by weight of an enzyme to each 100 parts of starch or converted starch and the resulting dextrose solution is kept at an appropriate crystallization temperature until discrete crystals, e.g. dextrose hydrate or anhydrous dextrose crystals, have formed and the crystals are then separated from the mother liquor. K represents the hydrolysing power of the enzyme and is determined as follows:-5 ml of a solution containing y grms of enzyme per 100 ml are added to a mixture of 25 ml water and 10 ml of a 1 per cent Lintner starch solution at pH 5.0 and the hydrolysis is allowed to proceed at 40 C. for 30 minutes. The percentage hydrolysis x is then determined. and K=10/3y log 10 100/100-x Between 60 and 80 per cent by weight of solids may be in solution before crystallization and it may be seeded e.g. with dextrose hydrate or anhydrous dextrose crystals. A dispersion having a maximum dextrose equivalent (dry basis) of 65 per cent by weight may be used and the minimum dextrose content (dry basis) after treatment may be 75 per cent.

Filed: 1939-09-25
Abstract: 532,908. Secret combination switches. WHITTLE, H., and BAYNES, S. Sept. 25, 1939, No. 26571. [Class 38 (v)] In a secret combination switch having a circle of depressible buttons 1 on a dial, depression of, say, 'four selected buttons in the correct order will rotate step by step a plate 11 to operate the switch; depression of any other button will rotate another plate 9 which will release the plate 11 causing this to return to its original position. The switch itself consists of a bar 6 pivoted at 18 and controlled by a dead-centre spring 17. It is moved into the "off" position by depression of a central push button 2 having a cam at its end which engages the side of the bar. To move it back into the " on position, the four selected buttons are depressed. They are relatively long and have wedge shaped ends which bear against projections 12 on the plate 11 rotating this step by step against a spring till a stop 13 engages the bar 6 and pushes this back across the dead-centre position. Return of the plate 11 is prevented by a ratchet mechanism 14 arranged between the plate 11 and the other plate 9. The other buttons are relatively short and depression of any one of them rotates a plate 9 in a similar way. This movement disengages the pawl of the ratchet from the teeth and the plate 11 returns to its normal position. Specification 458,688, [Group XXXI], is referred to.
