Title: Improvements in or relating to gas turbine power plants
Inventor: KRONOGARD SVEN-OLOF
IPC: F02C7/36
Filed: 1966-10-13
Abstract: 1,204,321. Gas turbine plant; turbines. TURBOKONSULT AB. Oct.11, 1967 Oct.13, 1966 , No.45726/66. Headings F1G and F1T. A gas turbine power plant comprising a gas generator and a main power turbine has an additional auxiliary turbine arranged in the same gas passage as the gas generator and the main power turbine, there being means to connect the auxiliary turbine to at least one power take-off other than a power take-off from the main power turbine and power transfer means to connect the auxiliary turbine to the gas generator and/or the main power turbine. The gas generator may be of turbine, free piston or rotary engine type. In a basic arrangement Fig. 1, a gas generator comprising a radial flow compressor 1, turbine 3, air pre-heater 21a and combustion chamber 20 supplies gas to an auxiliary turbine 5 in series with a main power turbine 7 driving an output shaft 8. The auxiliary turbine shaft extends forwardly at 4 and rearwardly at 6, to selectively provide an auxiliary power output, e. g. to accessories, and to assist the compressor driving turbine 3 and/or main turbine 7, as required. Many combinations of transmission mechanism are described. In one transmission arrangement, Fig. 30, the main turbine 7 and auxiliary turbine 5 contra-rotate and drive respective separate output shafts 12, 14 through reduction gearing. A connection between the turbines 5, 7, can be made by a free wheel 28 and/or a friction clutch 29. The free wheel 28 may be disconnected by a clutch 30. A shaft 15 extends forwardly to connect the auxiliary turbine 5 with the gas generator. A clutch arrangement (31) Fig.32 (not shown), may be provided for forward and reverse drive of shaft 12. In modifications, the connection between the turbines 5, 7, and between turbine 5 and the gas generator may include an infinitely variable transmission of electric, hydraulic, pneumatic or mechanical type. The auxiliarly turbine 5 may be either upstream or downstream of the main turbine 7. Fixed or variable turbine guide vanes may be provided. When variable guide vanes are provided, they can be used, for example, to control braking of the plant or the power distribution between the main and auxiliary turbines. In a further modification, Fig.14a (not shown), the auxiliary turbine 5 may be mounted upstream of the compressor driving turbine 3 and may drive a second radial flow compressor stage la. In Fig. 41a, (not shown), the turbine 5 drives an axial flow pre-compression stage (54b).

Title: Variable capacity refrigeration system
IPC: F25B41/04
Filed: 1965-11-01
Abstract: 1,105,190. Refrigerating. ALLIED CHEMICAL CORPORATION. 1 Nov., 1965 [2 Nov., 1964], Nb. 46148/65. Heading F4H. In a compression-condensation refrigeration system evaporated refrigerant is adjustably proportioned between two branch lines 19 and 20 leading to the compressor return line 9, the two branches being in heat exchange relationship with high side refrigerant by-pass lines 7B and 7A. The line 7A may pass gaseous refrigerant according to the setting of valves 10 and the line 7B may pass liquid refrigerant according to the setting of valves 8. There may be a single valve 16 controlling the proportions of evaporated refrigerant flow through the branch lines 19 and 20 or there may be two valves 17 and 18 which may be solenoid valves. The valves 8, 10 and 16 or 17 and 18 are controlled through pressure or electric lines 15 by a controller associated with a temperature sensor 13 in the evaporator space 14. When the refrigeration demand decreases, heat exchange between the lines 7A and 20 is utilized, the overriding effect being a decrease of refrigerant density in the compressor return line to reduce the rate of refrigerant flow round the circuit. When the refrigeration demand increases, heat exchange between the lines 7B and 19 is utilized, the overriding effect being a precooling of liquid refrigerant prior to expansion at a valve 5. The valve 5 is controlled by an evaporate, temperature sensor 11. The refrigerant used in the system may be chloropentafluoroethane, octafluorocyclobutane, perfluoropropane, chloroperfluoropropane, and sulphur hexafluoride. Reference is also made by way of comparison to monochlorodifluoromethane, and dichlorodifluoromethane.

The throttle valve 8 is actuated by sideways movement of the foot plate 12 to pivot the second lever portion 4 about the pin 3, the brakes are applied by depressing the foot plate to pivot both lever portions 1, 4 about the pin 2, and application of the brakes when the throttle is open results in a continuous automatic movement of the throttle valve towards the idling position as the distance between the arm 5 and one of the abutments 7 for the sheath of the cable 6 is progressively reduced. Unintentional application of the brakes when actuating the throttle is prevented by a blocking means 11 including a spring-loaded ball or plunger engaging a recess in the lever portion 1.
Patent GB-465890-A (GB)
Abstract: 465,890. Cash registers. NATIONAL CASH REGISTER CO. Nov. 16, 1935, No. 31752. Convention date, Nov. 17, 1934. [Class 106 (i)] Printing on bills and like inserted material.- In a cash register or similar accounting machine adapted to print identical data successively on two separately inserted record media at the same printing point, means being provided to suppress one printing stroke, in an amount entering operation controlled by a special key, the setting of the machine for a total-taking operation subsequent to such an amount entering operation maintains the suppression means effective without operation of the special key. The invention is described as applied to a Shipley machine of the kind described in. Specification 223,939, [Class 106 (i)], adapted for registering banking transactions. In the normal operation of such a machine each transaction is printed-on a passbook and ledger card by two actuations of a single printing hammer. In the absence of a passbook, the transaction is printed on the ledger card and a receipt slip, the transaction being subsequently entered in the passbook. In such a subsequent operation, according to the invention, the transaction is printed on the passbook only, the second actuation of the hammer being suppressed. For this purpose, supplementary keys are provided in the credit and debit transaction banks. Depressionof either supplementary key, positions a high spot 24, Fig. 2, on the corresponding printer rack 23, to prevent clockwise rocking of a lever 26 carrying a bail 27. After a normal operation, a hammer-actuating cam 41, Fig. 3, having two high-spots 57, 58 assumes its right-hand position in which both high-spots are in the plane of a hammer-operating bell crank 43. At the beginning of a succeeding operation, the cam is shifted leftward to the position shown by a cam 35 acting through a pitman 30, latch arm 28, pin 37, shaft 38 and arm 39. In this position, the wide high-spot 58, only, is in the plane of the operating bell crank. Later in the operation, the cam returns the latch to the right and, in normal operations, the pin 37 being engaged within a recess 60 in the latch, the shaft 38 and cam 41 are also returned to the right to render both high-spots operative to actuate the hammer. However, in an operation in which a supplementary key is depressed, the latch is rocked clockwise by the bail 27 and is ineffective to return the cam, with the result that the high-spot 58 only becomes operative. A bar 67 bearing on the bail 27 positions an indicator 73 to show whether the machine is making a single or a double impression. In a total-taking operation, following a supplementary operation, a locking arm 78, carried by the usual shaft 77 that is rocked during total taking, intercepts a stud 76 on the bar 67 to maintain the bail and latch in depressed position and thus suppress the second hammer actuation.

The chip is then immersed in a nickel chloride plating bath and connected first as anode to clean the surface of layer 17 and then as cathode to deposit nickel 21, which is further built up by electroplating in a nickel sulphamate bath and then gold plated to prevent it tarnishing. After removal of the photoresist the layers 16, 17 where not protected by the nickel 21 are etched away in a mixture of ceric sulphate and sulphuric acid. The chip may then be mounted to an insulating substrate by inverting it to bring the land 21 and any other similar lands into contact with solder coated lands on the substrate and heating to fuse the solder.
