Title: Thermopump heating systems
IPC: F24H4/02
Filed: 1947-10-07
Abstract: 652,214. Power-generating systems. EVANS, J. H. Oct. 7, 1947, No. 30402/49, Divided out of 652,162. [Group XIII] [Class 122(iii)] [Also in Group XIII] In an electric power generating set, the turbine 4 exhausts into a condenser 6 and the normal cooling of the condenser is replaced by the use of a suitable refrigerant so that the steam condenser also performs the function of a refrigerant evaporator. A refrigerant compressor 17 driven by the turbine draws refrigerant through pipe 18 and delivers it through pipe 19 to a series of condensers 20, 20A in which water is heated for a district heating system. The refrigerant leaves by pipes 26 and is collected in a receiver 27 and passes through a liquid cooler 28 and pipe 30 to an evaporator control device 29, as described in Specification 652,162, [Group XIII], and thence to the condenser 6. The refrigerant leaving the condenser 6 passes through the evaporator control device 29, pipe 34, cooler 28 from which it returns through pipe 18 to the compressor 17. Water leaving the condensers 20, 20A by pipe 24, controlled by a thermostatically controlled valve 35, enters the storage tank 36. The water passes from the tank 36 through the flash steam recovery vessel 38, a calorifier 39 and is pumped to the district through a pipe 45; the calorifier 39 may be fed with live steam through a thermostatically controlled valve 43. The water returns from the district through the pipe 46 to the condensers 20, 20A. If the temperature of the water in the storage tank 36 rises, a valve 47 is opened so that it is pumped to a cooling tower 49. A header tank 52 is provided. The condensers 20, 20A may heat water for any form of heating in the district and a separate similar system may be provided having condensers 21, 21A for heating water for the domestic supply of the district.

Filed: 1963-07-31
Abstract: 971, 300. Reactors. BABCOCK & WILCOX CO. July 31, 1963 [July 31,1962], No. 30462/63. Drawings to Specification. Heading G6C. In a pressurised water reactor, the pressure vessel contains the core and heat exchangers in which both superheated and saturated steam are produced. The circulation of fluid through the core and the exchangers is effected by natural convection. The pressure of the core coolant is maintained by electric heating elements which maintain the temperature of part of the core coolant above that of the remainder, the boiling of which is thus prevented. Reduction of the core coolant pressure is effected by spraying cold coolant into the pressure vessel. Vapour-liquid whirl separators and scrubbers are placed between the saturated steamand the superheater heat exchangers, which are mounted to permit vertical thermal expansion. Vertical control rods are positioned between the fuel elements and are adjusted from the pressure vessel upper surface. Thermal shields are arranged concentrically round the core within the pressure vessel,

[Also in Divisions B1 C3, G2] A process for monitoring the concentration of living polymer chains in a polymerisation reaction mixture comprises removing a sample from a homogeneous solution reaction zone and comparing the light absorbance characteristics of a measuring sample for different narrow band wavelengths of transmitted radiation having different absorption characteristics for the active chromophores associated with said living polymer chains. The results may be shown graphically or used to control arid modify the polymerization process. In the preferred procedure, samples are removed from polymerization zone 10 and fed to measuring cell 18, through which light passes from source 28. The transmitted beam is then divided by semi-transparent mirror 30 and each beam passes through an optical filter 32, 34 to a photo-tube 36, 38, and the outputs of the phototubes are amplified and compared in control station 40. The process may also be applied to monitoring the purification of the reactants prior to polymerization. In examples (I) the preparation of styrene-b-isoprene-b-styrene copolymers is described, using butyl lithium initiator and in cyclohexane, in which the polystyrene block formation is monitored. Analogous monomers, solvents and initiators are stated in (II) to give similar results.

[Class 110 (ii)] A rotary compressor or pump comprises a rotor 14 having a number of spiral-shaped grooves 15 in its periphery, and rotary abutments 18 on shafts 33, which have lobes 19 fitting into the grooves to impel fluid which enters the grooves by way of inlet ports in the stator to delivery ports 21. Sliding valves controlled by hand 24 may be provided to vary the point at which the delivery ports are opened to a groove and so control the degree of compression of a fluid. Anti-friction linings 13 may be fitted to the stator bore. The grooves may be circular or involute shaped in cross-section, and may so mesh with the lobes 19 as to drive the abutments. Normally the main shaft 12 and the abutments shafts 33 are driven by synchronous motors, through gearing or other means may be used to drive the shafts 33. The mountings for motor driving shafts 33 may be adjustable. The inlet and delivery ports may be in the rotor or in the abutments as described in modified arrangements. The inlet ports may be controlled by valves. A three stage compressor is described in which the three stages are similar except for the diminishing sizes of the rotor grooves and meshing lobes. Fig 15 shows the valves 41 ... 43 controlling the delivery valves of the three stages A, B, C, and further valves 52 in a chamber 50, which control the byepassing of fluid from outlet ports 54, to inlet ports 53, for each stage. A push rod below and parallel to a guide 49, upon which sleeves 48 slide, is provided with cam grooves each with a roller within which actuates a hinged lever 56 which in turn engages sleeves 48 and so moves the valves 41 ... 43 to right or left. Stops 63 limit the axial travel of pins 45, but the valves 41 ... 43 may be moved further to the left against springs 47. In a modification wherein the fluid is delivered through ports in the rotor, the delivery is controlled by a rotary valve controlled by worm and worm gear. In a further arrangement in which fluid is delivered through passages in an abutment, the delivery pressure is controlled by a valve upon a sleeve around the abutment shaft, which is rotated by means of a projecting arm. The passages in the abutment may be duplicated upon the two faces.

Title: Improvements in and relating to an output stage without a relay used in a double-current impulse operation
IPC: H04L27/14
Filed: 1960-09-09
Abstract: 907,343. Type-printing telegraphy. TESLA NARODNI PODNIK. Sept. 9, 1960 [Sept. 19, 1959], No. 31162/60. Class 40 (3). The invention provides the output stage of a double current telegraph receiver, the circuit being as in Fig. 1. The double current code element signals u, Fig. 1, are applied to the bases of transistors T 1 , T 2 . When the base of T 1  is negative relative to the base of T 2 , T 1  conducts and current flows through this transistor and through the transmission line Rz from battery B 1 . When the polarity of the signal u is reversed T 2  conducts and current flows from B 2  to the line. A circuit incorporating the output stage, Fig. 2, which is used for the reception of frequency shift signals, comprises means for automatically switching the receiver to a state corresponding to the reception of a Start signal if the telegraph circuit is broken. Tuned transformers Tr 1  and Tr 2  respond to frequencies f 1  and f 2  respectively, and feed transistors T 3  and T 4  of a monostable multivibrator. Resistors R 8  and R 9  have different values and to compensate for the asymmetry Tr 1  and Tr 2  have different transformation ratios. When frequency f 1  is received T 3  conducts. The voltage at the base of T 1  therefore falls and thus T 1  also conducts. The operation is analogous for frequency f 2 . Should the telegraph circuit be broken the multivibrator T 3 , T 4  switches to the state dependent upon the ratio of the resistances R 8 , R 9 .
