IPC: F15B15/12
Filed: 1953-11-13
Abstract: 753,237. Centrifugal pumps; hydraulic turbines. ENGLISH ELECTRIC CO., Ltd. Nov. 12, 1954 [Nov. 13, 1953]. No. 31547/53. Classes 110(1) and 110(3) [Also in Group XXIX] In a hydraulic turbine or a centrifugal pump in which the pitch of the runner vanes 102 is controlled by a rotary servomotor built into the runner, means are provided for transmitting the motion of that part of the servo-motor which rotates relative to the runner to a return motion rod 5 from which the distributor valve 13 of the servo-motor is derived. The servo-motor comprises a cylindrical casing 30 fixed to the runner shaft 3 and to the runner hub 105 and an inner drum 32. The annular space between the casing 30 and the drum is divided into compartments bounded by radial walls 33, 34 on the casing and drum respectively. Alternate compartments may be connected through ducts 36. 37 to concentric ducts separated by a tube 4 fixed in the runner shaft 3. The concentric ducts are connected through radial bores 6. 7 and annular grooves 8, 9 in a self-aligning bearing 10 to the distributer valve 13. The inner drum 32 has a shaft 114 carrying a radially slotted member 115 engaging slider blocks or rollers 111 on arms 110 carried by the trunnions 108 of the runner vanes 102. The return motion rod 5 is prevented from rotation relative to the runner shaft 3 by radial arm 23 guided in slots 24 and carrying a ring 22 surrounding the shaft 3. A transverse bar 35 fixed to the bottom of the rod 5 slides relative to a pair of helical cams 38 fixed in the drum 32 so that as the drum turns relative to the casing 30 the rod 5 is moved vertically causing the ring 22 to operate on a lever 20 controlling the leakage of pressure oil from the inner rod 14a of the distributer valve 13. The valve 13 may be of the kind described in Specification 729,493 and has a main valve piston 14 carrying a bracket 14b to which a lever 15, connected to the inner rod 14a is pivoted. The lever 15 may be operated by a speed governor in the case of a turbine, or at will by an operator in the case of a pump. In a modification, Fig. 2, the return motion rod 202 carries a rudimentary double-start nut member 234 with a pair of helical parts 235 engaging oblique-faced blocks 237, 238 fixed to the runner hub 205. Projections 233 between the helical portions 235 prevent the rod 202 rotating relative to the rotary part 232 of the servomotor. In a further modification the relative rotation between the runner hub and the rotary part of the servomotor transmits an axial motion to the return motion rod by an arrangement of links and bell crank levers.

Title: Refrigeration systems
IPC: F25B1/053
Filed: 1964-08-05
Abstract: 1,070,847. Automatic temperature control systems. CARRIER CORPORATION. Aug. 5, 1964 [Sept. 25, 1963 (2)], No.31859/64. Heading G3R. In a fluid moderating system, such as a refrigerating apparatus, the temperature of fluid entering and leaving the system is measured so that one temperature measurement modifies the other. A sensor 45 comprises a negative temperature coefficient resistor 36 in intimate thermal relationship and a positive coefficient thermistor 37 in less intimate relationship with the leaving fluid, which resistors form with resistors 39-43 and centre tapped transformer 31-34 an A.C. bridge, the output of which is modified by a negative coefficient resistor 61 in the fluid entering line. The angular displacement of the bridge output via potentiometer 39 from lines 33, 34 fires one of the thyristors 75, 78 which fire through transformers 80 or 100, further thyristors 93 or 111 which load shading windings 96 or 97 of a reversible motor 95 controlling a damper in the refrigerant line 27. The damper shaft 15 may be coupled to the potentiometer slider to give positive or negative position feedback. A rise in temperature in the fluid leaving line 45 causes an immediate response from resistor 36 which is later modified by thermistor 37 in the opposite direction thus avoiding overshoot. Resistor 61 also modifies the effect of resistor 36 causing the bridge to balance at a lower outlet temperature when the inlet temperature is high and vice versa. A motor overload protective circuit is provided which comprises a current transformer 120 which on small overloads fires a thyristor 131 which clamps the thyristor 75 non conductively thus preventing further load being placed on the compressor motor. Higher overloads will trigger another thyristor 130 which fires thyristor 111 rotating motor 95 to unload the system until thyratron 130 ceases to be triggered in which state the system continues until thyratron 130 also ceases to conduct. In an alternative arrangement the temperature sensitive resistors 36, 61 are serially connected in one arm of an A.C. bridge circuit.
