Title: Thermostatic valve device
IPC: G05D23/12
Filed: 1943-01-27
Abstract: 563,195. Thermostats; refrigerating. DEHN, F. B. (Mills Novelty Co.). Jan. 27, 1943, No. 1396. [Classes 29 and 64 (ii)] In a thermallyoperated valve for controlling the cooling water in a compression refrigerating apparatus actuated by vapour pressure in a thermally sensitive bulb connected to a responsive element such as a bellows, undue condensation of vapour in the bellows and loss of liquid from the bulb, is prevented by keeping the bellows temperature above that of the bulb. In Fig. 1, refrigerant from a compressor 10 is cooled by water in a counter-flow condenser 11, and passes into a liquid receiver 12 and thence through an expansion valve 16 into an evaporator 17. Cooling water, after passing through the condenser 11, passes through pipe 19 to the water jacket of the compressor 10. The flow of cooling water leaving the compressor is controlled. by valve 26, Fig. 3, carried by bellows 28 to which vapour pressure is transmitted by pipe 31 from bulb 30. The bellows is heated by a jacket 34 through which passes the hot gas delivered by the compressor. Alternatively, the bellows may be heated electrically by a surrounding coil, or by a jacket through which water from the compressor jacket passes. The control valve 26 may be on the inlet side of the compressor jacket.

Title: Improvements in or relating to electronic counter or like circuits including a plurality of gas-filled discharge valves
IPC: H03K23/82
Filed: 1952-01-18
Abstract: 713,475. Electronic counting-apparatus. GENERAL ELECTRIC CO., Ltd., FISHER, S. F., and PEDDLE, E. A. R. Jan. 13, 1953 [Jan. 18, 1952], No. 1518/52. Class 106 (1). [Also in Group XL (c)] A multistable state electronic counter comprises the cascaded connection of at least two counting chains each of which comprises a chain of separate gas-filled discharge tubes and means to change over the H.T. supply from one chain to another chain immediately after the last tube in the first chain has fired. In this way the tubes in one chain are de-ionized whilst those in a second chain are being sequentially fired by the incoming pulses to be counted. Fig. 1 shows a pulse counter comprising two counting chains of coldcathode gas discharge tubes 1 ... 5 and 6 ... 10 respectively. Incoming positive-going pulses are applied at 13 to the trigger electrodes of all the tubes and the H.T.+ supply at 25 is switched with contacter 24 as shown to apply H.T.+ to tubes 1 ... 5 only. The first pulse fires tube 1 which primes tube 2 so that it fires on the second pulse and subsequent pulses cause the tubes to fire sequentially until tube 5 fires when the high speed relay 19 in its cathode circuit is energized and contacter 24 changes over to disconnect the H.T.+ supply from tubes 1 ... 5 and to connect it to tubes 6 ... 10. Thus the next five incoming pulses at terminal 13 cause tubes 6... 10 to fire sequentially, the firing of tube 10 causes high speed relay 20 to be energized and contacter 24 to revert to the position shown. The resultant pulses occurring at the cathodes of tubes 1 ... 10 when the tubes are conducting are differentiated, clipped and shaped to produce short pulses which occur at the time of occurence of the leading edges of the pulses appearing at the output terminals T1 ... T10. In a modification shown in Fig. 3 the high speed relay is replaced by an electronic switch comprising a trigger-pair 40 which is switched at 30 and 31 by the voltages appearing across the cathode resistors 18 of the tube 5 and 10 respectively, Fig. 1, to connect the H.T.+ supply at 34 to the outputs 32 and 33 in dependence upon which of the valves 38, 39 is conducting ; the outputs 32, 33 being connected respectively to the lines 15 and 16 of the counter of Fig. 1.

Title: Improvements in slack balloons with elastic deformation
IPC: B64B1/60
Filed: 1927-01-24
Abstract: 267,473. Avorio, L. March 13, 1926, [Convention date]. Aerostats.-A non-rigid aerostat for a captive balloon or dirigible is provided with an air balloonet the external wall of which is elastic. In the captive balloon shown in Fig. 1, the line a<1> represents the line of attachment of the diaphragm between the gas and air chambers. The portion b of the envelope below the air chamber is made elastic by fastening to it at frequent intervals fabric sheaths d, Fig. 7, through which are threaded elastic cords c fastened at their ends to the envelope and covered with braided woven matrial to minimise friction. At high altitudes the expansion of the gas causes the complete collapse of the air chamber, the diaphragm a lying against the envelope as shown in Fig. 1 and the elastic portion b being fully stretched. As the altitude decreases, the decrease in the volume of the gas is taken up partly by air entering the air chamber and partly by a construction of the elastic portion b in which are formed parallel' longitudinal pleats as shown in Fig. 4. By this means the envelope is maintained taut without varying its shape or size to any appreciable extent.
