Title: Heat transfer rate control
IPC: G05D23/19
Filed: 1973-04-26
Abstract: 1433921 Refrigerating; defrosting; tubular heat exchange elements GENERAL CRYOGENICS Inc 26 April 1973 [5 May 1972] 20007/73 Headings F4H and F4S Defrosting of the evaporator of a refrigerator system is initiated when the temperature of refrigerant leaving the evaporator and the temperature of air passed through the evaporator are in a predetermined relationship. As shown, the refrigeration system comprises a container 10 for liquid N 2 , an evaporator 12 having an outlet to atmosphere through a silencer 100 and a fan 104 for circulating air in the cargo compartment of a vehicle over the evaporator. The system also includes a vaporizer 64 and a gas-fired heater 16 in which the N 2  passes through a coiled conduit, Fig. 8. The control system includes thermistors 136, 138, located respectively in the evaporator outlet and in the cargo space adjacent the fan and connected to a resistance bridge 128, and a temperature controller 56 having a capillary temperature sensor 56a. Cooling.-During normal cooling, the pressure of N 2  vapour in the container 10 acts through line 62, valves 43a, 52 and line 50 connected to an actuator 43 to hold a valve 42 open. Liquid N 2  from the container 10 passes through the valve 42 to coils 46 of the evaporator 12. The vapour then drives a pneumatic motor 94 of the fan 104 before passing through further evaporator coils 48 to the outlet. Defrosting.-When the temperature detected by the thermistor 138 reaches a predetermined value, e.g. 28F, above that detected by the thermistor 136 the resistance bridge network becomes unbalanced and causes the line 50 to be vented to atmosphere, thereby closing valve 42. Liquid N 2  from the container 10 now passes through the vaporizer 64 to the heater 16, from which heated gas flows through a line 70 to the primary and secondary coils 46, 48 of the evaporator. Defrosting is terminated when the resistance bridge network returns to the balanced situation. Heating.-When the thermostat 56t of the temperature controller 56 calls for heating, N 2  is heated and passed to the evaporator, as in the defrosting operation.

Title: Carbohydrate derivatives and processes for making same
IPC: C08B11/08
Filed: 1933-07-17
Abstract: Mixed ethers of carbohydrates are prepared by subjecting to alkylation or aralkylation an alkali-soluble oxyalkyl derivative of a carbohydrate, which has been prepared in the presence of alkali.  The products may be soluble in water and in benzene.  The parent material may be one in which not less than two and preferably not less than three molecules of oxyalkylating agent have been used in the oxyalkylation of one molecule of carbohydrate.  The alkali-soluble oxyalkyl derivative may be alkylated in dilute solution, for instance in a solution containing not more than three per cent of the oxyalkyl derivative.  Suitable processes for alkylation or aralkylation are those described in Specifications 12854/12, 6035/13, 149,318, 149,320, 163,018, 177,809, 181,393, 181,395, 200,815, [all in Class 2 (ii)], and 427,387.  In an example, an 8 per cent solution of alkali-soluble ethylene (or propylene) glycol ether of cellulose, or glycerine ether of cellulose in caustic soda solution is etherified by means of di-ethyl sulphate.  In other examples, a 3 per cent solution of propylene glycol ether of cellulose or glycerine ether of cellulose in caustic soda solution is etherified by means of di-ethyl sulphate; a 6 per cent solution of ethylene glycol ether, propylene glycol ether, or glycerine ether, of cellulose, in caustic soda is etherified by means of di-ethyl sulphate in two stages with the addition of caustic soda and di-ethyl sulphate between the stages; an alkali-soluble ethylene glycol ether, propylene glycol ether or glycerine ether of cellulose, is mixed with caustic soda solution and heated with ethyl chloride which may be diluted with benzene; an alkali-soluble ethylene or propylene glycol ether or glycerine ether of cellulose, is mixed with caustic soda solution, powdered caustic soda, and sodium carbonate, and etherified with ethyl chloride. Other examples are given in which the alkali-soluble parent material is prepared by the action of ethylene oxide on cellulose in the presence of caustic alkali.  In other examples, starch or dextrin is reacted with ethylene chlorhydrin or a -monochlorhydrin in the presence of caustic soda and then etherified with ethyl chloride or di-ethyl sulphate.  The products may conveniently be separated by acidification of the solutions in which they are obtained, followed by heating, or by acidification followed by dialysis, filtration, and precipitation by evaporation or addition of alcohol.  Specifications 231,807, [Class 2 (ii)], and 427,386 also are referred to.

Filed: 1973-04-27
Abstract: 1430109 Flash arrangements for cameras AGFA-GEVAERT AG 27 April 1973 [28 April 1972] 20208/73 Heading G2A A camera comprises drive means having first 1 and second 30 drive members which are released by a shutter release 2 and actuate a shutter and an ignition member for percussively ignitable flash-lamps respectively; the second drive member only being released when a flash-lamp is positioned in the flash-lamp socket 6 of the camera. Drive members 1 and 30 are biased to rotate in a clockwise direction by springs 15 and 31 respectively. Member 1 is retained in the position shown by a lug le engaging the shutter release 2 and member 30 is retained by a stop 30b engaging a surface 1b on member 1. When release 2 is actuated member 1 rotates clockwise to operate a thrower member 3 which controls the shutter 16. When surface 1b moves, the drive member 30 is also free to rotate clockwise and a stop 30a on member 30 engages the end 8b of the ignition member 8 to actuate the flash-lamp. If a flash-lamp is not inserted in the socket 6, Fig. 1 (not shown) a feeler 12 is pushed into the socket by a control lever 10, which co-operates with a stop 12a on the feeler and is biased by a spring 11. The control lever 10 pivots anti-clockwise and moves the ignition member 8, to which it is coupled by a spring 9, to an inoperative position in which the end 8b is out of the path of the stop 30a. Also a locking lever 34, which is biased by a spring 33 and cooperates with a stop 8d on the ignition member, moves to a position in which it engages the edge 30c of member 30. Thus when release 2 is actuated only drive member 1 rotates to operate the shutter, the drive member 30 being retained stationary by the locking lever 34.

Title: Improvements in Gas Turbine Engines
IPC: F01D3/00
Filed: 1967-05-03
Abstract: 1,179,797. Gas turbine jet engines. GENERAL ELECTRIC CO. May 3, 1967 [Sept. 26, 1966], No.20448/67. Headings F1G, F1J and F1T. In a gas turbine engine, e.g. a by-pass or turbojet engine, the rotor of a compressor 21 and the rotor of a turbine 23 are inter-connected and journalled for rotation by three axially spaced bearings 27, 28 and 27 supported by frame members 31, 32 and 33, respectively, extending to the engine casing 34. Members 60 and 65 connected to the frame member 32 define an annular chamber 63 surrounding the bearing 28 and sealed by annular seals 61 and 66. The chamber 63 is vented to a downstream point in the gas stream through the engine through openings in the member 64. A duct member 51 between the compressor 21 and turbine 23 defines in part an annular chamber 76 in free communication with the hot gas stream entering the turbine 23. An annular seal 73 is provided between the turbine rotor and the duct member 51. An aperture 67 in the duct member 51 provides for the passage of compressor discharge air to the chamber 68. The chamber 62 communicates with the gas stream immediately downstream of the compressor 21 and the chamber 83 communicates with the gas stream immediately downstream of the turbine 23. When the engine is in operation, the pressures in the chambers 62, 68, 76 and 83 produce axial forces which when added to the reaction forces on the compressor and turbine blades produce a resultant axial force on the thrust bearing 28 which is minimized by selecting the position of the annular seal 73. The turbine blades 43 have passages therein for cooling air which flows from the chamber 68 through openings 74. Air from the compressor 21 passes through a duct 139 to the radial frame members 33 and to an annular manifold 79. The rotor of a fan 11 and the rotor of a fan turbine 14 are inter-connected by a shaft (130), Fig. 3 (not shown), and jounalled in three roller bearing 29 and a thrust bearing 30 supported by the radial frame members (31, 33 and 35). Chambers (118, 127, 127A and 132), Fig. 3, defined between the inter-connected rotors and members secured to the engine casing (34) communicate with the gas stream through the engine and produce axial forces which together with the reaction forces on the fan and fan turbine blades produce a resultant axial force on the thrust bearing 30. This axial force is minimized by selecting the position of annular seals (124, 125) between a manifold (122), supplied with compressor discharge air, and two of the pressure chambers (127 and 127A). Compressor discharge air is also supplied to the downstream face of the fan turbine rotor through the radial frame members (35) and an annular seal (135).
