Title: Turbine speed controlling valve operation
IPC: F01D17/06
Filed: 1973-04-16
Abstract: 1385452 Prime mover control; speed measurement WESTINGHOUSE ELECTRIC CORP 16 April 1973 [26 April 1972] 18227/73 Heading G4H A prime mover speed control system utilizes a digital computer to control metering of operating fluid and has as one of the computer inputs a digital speed signal processed from pulses produced by a rotary displacement encoder on the prime mover output shaft. Displacement pulses from the inductive displacement pulse generator 58 are fed via gate GPC to counter PC and clock pulses TP of considerably higher frequency than the displacement pulses are fed from oscillator OSC via gate GTC to counter TC. The system uses two methods of calculating the speed; (a) the number of displacement pulses in a given time (number of clock pulses) is measured and (b) the time (number of clock pulses) for a given number of displacement pulses is measured. Method (b) is more accurate at higher speeds but (a) is preferable at low speeds because of its shorter measuring period. Readings are taken using both methods at the same time and the computer calculates the speed from both but uses the result from (a) below a predetermined speed and (b) above it. Predetermined different numbers are entered from the computer into registers RP and RT. Both counters are initially zeroed and start counting together. For method (a), when the value in counter TC equals that in register RT, a signal is sent from comparator CT to the computer and the value in counter PC is input to the computer. The value in register RT is then changed to twice its original value or the equivalent value if this would overflow the counter. For method (b) the signal from comparator CP signals the computer to input the reading in counter TC and also, by a signal on line INT closes gate GTC. This is necessary because the high rate of clock pulses could cause changes of reading during computer input and could cause count errors. The value in register RP is updated in the same way as that in RT. Gate GTC is opened by the next displacement pulse to ensure synchronism in the renewed count.

Title: Improvements in or relating to absorption machines for producing cold or heat
IPC: F25B15/12
Filed: 1929-06-14
Abstract: 313,618. Siemens - Schuckertwerke Akt.-Ges. June 16, 1928, [Convention date]. Refrigerating, absorption systems for.-Systems wherein heat or cold is produced by evolution of gas from and absorption in solution in the presence of an inert gas are modified by utilizing inert gas additionally either in the heated generator or in the cooled reabsorber parts of the system. Condensation and evaporation of liquefied refrigerant at an intermediate temperature and partial pressure may take place in addition to evolution from low temperature solution. Various combinations of cycles of refrigerant, solution and inert gas are described in the Specification with reference to diagrams. In one example, shown in Fig. 1, a heated generator K contains aqueous sulphuric acid, from which water vapour as refrigerant is generated in the presence of nitrogen as neutral gas. The gas mixture flows as indicated in dotted lines to a reabsorber R, where the water vapour is absorbed, and the nitrogen returns to the generator K. Refrigerant vapour and inert gas (hydrogen), also circulates as shown by the dotted lines between the low-temperature generator or cold producer E and an absorber A. while the solution flows as indicated by full lines between the absorber and hot generator and between the reabsorber and cold generator. Pressure equality may be obtained by cross-connections, not shown, or inequality may be balanced by liquid columns. Pressures above or below atmospheric may be employed. In an ammonia-water system shown in Fig. 2, a third partial pressure zone is provided by a condenser C and evaporator V. Liquid circulates as shown by full lines between the absorber A and heated generator K and between the reabsorber R and cold producer E, while inert gas circulates between the vessels E, A and the vessels R, V respectively. Gas evolved in the hot generator K is condensed at C and flows therefrom as liquid to the evaporator V, where useful cold of moderate temperature is produced by evaporation into inert gas. The system shown in Fig. 10 comprises a generator 1 heated by an element 2, a gas separator 4, an absorber 6 cooled by a water coil 17, a reabsorber 9 cooled by a coil 15, a further reabsorber 23 not included in the inert gas circuit, a gas separator 10, and a low-temperature generator or cold-producer 12. Solution circulates through heat exchanging conduits 5, 22 between the absorber 6 and the generator 1, through conduits 25, 8, 11 between the cold producer and the reabsorbers. The inert gas circulates through passages 13, 14, 16 between the absorber, the cold producer, and the reabsorber 9, circulation being induced by a nozzle 19 supplied from the gas separator 4. A heat exchanger is provided in the gas circuit. Variation of effect in the various systems may be obtained as by choice of quantity of liquor in the several parts of the systems. Specification 279,898 is referred to.

[Also in Division H1] A steel anti-implosion clamping band 7 which is initially smaller than the cathode-ray tube faceplate 1 it is to surround, is applied to the tube by first coating the tube with thermal insulation, then heating the band 7 so that it will slide into position, preferably with one edge against a mould match line 17, and then allowing the band to cool and shrink into place. The temperature to which the band is heated may be 450‹ C. and should be such that on shrinkage the band is tensioned to its yield point in spite of the tolerances in dimensions of the band and of the faceplate. When the band is entirely on the cone side of the mould match line a tensile force of 500-700 Kgm is required, and this may be obtained by reinforcing the band with a separate band 8, or by folding over the edge of the band either outwards or inwards (Figs. 3 and 4, not shown) possibly with a reinforcing band arranged in the fold (Figs. 5 and 6, not shown).
