IPC: F24F5/00
Filed: 1965-10-22
Abstract: 1,105,095. Heating & cooling buildings; heat pumps. INTERNATIONAL STANDARD ELECTRIC CORPORATION. 22 Oct., 1965 [26 Oct., 1964], No. 44754/65. Headings F4H and F4U. A heating and cooling system for a multiroom building comprises a plurality of room units each consisting of a refrigerant condenser 13, a refrigerant evaporator (not shown) in heat exchange relation with a stream of room air, a heating coil 31 positioned downstream of the evaporator in said room air stream and a valve 23 by means of which water from a supply line 21 may be supplied either to the condenser 13 or coil 31. Water from the units is returned through line 29 and pump 41 to a valve 43 which regulates the relative proportion of water passing to a boiler 45 and a by-pass line 47, the water from the by-pass line and/or the boiler then passing to a valve 51 which regulates the relative proportion passing to a cooling coil 55 and through a by-pass line to supply line 21. As shown the units are grouped into an exterior zone and an interior zone and the temperature of the water supplied through line 21 is regulated in accordance with the outside temperature by a controller 65 which regulates valves 43 and 51. Thus when the outdoor temperature is at or below 40 F., water at 130 F. is supplied through line 21, valves 71 and 73 are positioned to connect the units of the exterior zone in parallel with those of the interior zone and the valves 23 of all of the units are positioned by room thermostats 33 to direct hot water to coils 31. The refrigerator systems are inoperative, all of the return water is heated in boiler 45 and cooling coil 55 is by-passed. At outside temperature of 50 F. the supply water is at 120 F., the exterior zone units are on heating and valves 71 and 73 are positioned to connect the units of the two zones in series, the water from the exterior zone unit being at a suitable temperature for providing either moderate heating or condenser cooling, as desired, in the interior zone units. At outside temperatures of 60 F. supply water at 110 F. provides moderate heating in the exterior zone and is then used to cool the interior zone condensers where it picks up sufficient heat to enable the boiler to be by-passed. At outside temperatures of 70 F. the supply water is at 100 F., valves 71 and 73 are positioned to connect the units in parallel some of the exterior units are on cooling and some on heating, all of the interior zone units are on cooling, the boiler is by-passed and some of the heat picked up from the condensers is dissipated in coil 55. At outside temperatures of 80 F. and above all units are on cooling and all of the water is passed through cooling coil 55 the cooling effect of which is now increased by providing water sprays, evaporative surfaces &c. in addition to air cooling by fan 57. In a modification (Fig. 9, not shown) the units are provided with on/off valves (75) which when closed direct water from the condenser to the heating coil so that the latter reheats air which has been cooled and dehumidified by the evaporator.

Title: Improvements in inter-connected transformer circuits
Inventor: SIMMS TERENCE EDWIN
IPC: H02M7/06
Filed: 1961-12-21
Abstract: 948,981. Rectifying. ENGLISH ELECTRIC CO. Ltd. Dec. 19, 1962 [Dec. 21, 1961], No. 45816/61. Heading H2F. The invention relates to polyphase transformer circuits in which two transformers have star and delta primary windings respectively connected in series, and polyphase secondary windings. According to the invention a pair of such transformers have tertiary windings interconnected so as to prevent unequal voltage distribution between the transformers when on no load. This avoids the necessity of matching the transformers. One transformer may have a single-phase tertiary winding and the other two single-phase tertiary windings, all three being connected in series. If the transformers are of the three-limb type then the single winding of the first transformer will be on its centre limb. The two transformers in the Figure are interconnected by two such arrangements and are shown supplying a polyphase rectifier. In another embodiment both transformers have three-phase tertiary windings, one being in star connection and the other in delta connection. The two windings. are then connected in parallel.

Title: Improvements in or relating to electromechanical actuators
IPC: H01L41/083
Filed: 1968-09-27
Abstract: 1,240,286. Valves. PHYSICS INTERNATIONAL CO. 27 Sept., 1968 [27 Sept., 1967], No. 46110/68. Heading F2V. [Also in Divisions F1, G3 and H2] A fuel-injection valve is controlled by an electro-expansive body 54, Fig. 3, such as a piezo-electric element, having a surface 56 for transmitting the movement of the body through a non-compressible fluid in a chamber 58 to a smaller surface 60. The latter forms part of a pilot valve which allows pressurized fuel to flow through passages 62, 64 to lift a plunger 86 and the valve 76 against a spring-load 78. The fuel beneath the plunger escapes through passages 66, 90 when the pilot valve returns to its original position and the actuating time of the valve is proportional to the magnitude of the electric signal applied to the body 54. Fig. 4 shows a modification in which the pilot valve 100 opens to operate a differential piston 108, 114 which applies an increased pressure to a downwardly facing conical surface on the injector valve 120. One-way fuel flow into the passage between the differential piston and the injector valve is provided by a spring-loaded valve 126. In a further modification, the differential piston is omitted and the pilot valve is arranged centrally and constructed so that its downward movement first applies an upward pressure equal to the spring-loading on the injector valve before pressurized fuel is admitted to lift the latter. A central exhaust passage may be provided through the pilot valve so that the injector valve can be lifted more rapidly against its spring. The surface of the electro-expansive body may act through the non-compressible fluid on a plunger secured to the injector valve, the pilot valve being omitted, and as shown in Fig. 7, the body 180 may be cylindrical and force fluid through passages 192, 194 to lift a plunger 196. The valve may also be constructed so that the number of fuel injection parts uncovered is proportional to the voltage applied to the electroexpansive body. A further construction in which the closure member consists of two coaxial members operated in succession by separate electroexpansive bodies permits flow durations of 100 microseconds to be achieved.

Filed: 1967-10-13
Abstract: 1,177,158. Indicating elevation. BRITISH AIRCRAFT CORP. Ltd. 9 Oct., 1968 [13 Oct., 1967], No. 46892/67. Heading G4H. [Also in Division G1] Apparatus to indicate the angle of elevation of a gun barrel, 2, about an axis AB includes a mounting 8, pivoted at EF about a saddle 10, secured to the barrel, which mounting supports a motor 12 forming part of a control loop which maintains a clinometer 18, on the output shaft 16 of the motor, in a horizontal attitude. An electrical signal is fed to a revolution totalizer counter which indicates at windows, 24, changes of the relative angular position of the clinometer and the mounting, which changes may be compared with a required elevation indicated at windows 26. The clinometer which comprises a convex, closed tube with an electrode at each end and one in the middle and an electrolyte containing an air-bubble, supplies an A.C. bridge (32), Fig. 2 (not shown), the output of which is rectified (36) and controls the p.r.f. of an oscillator (38) which drives pulse-actuated stepping-motors 12 and 28, an amplifier (44) and discriminator (46) controlling the direction of rotation of the motors. In order to maintain the axis GH (at 90 degrees to that, CD, of the barrel) of the output shaft horizontal, a second clinometer 48, controls a motor 50 which operates through gear-box 52 and a gear 54 to pivot the mounting about the saddle. A third clinometer 60, sited on the saddle and activated by a switch 58 indicates when the axis CD is horizontal so the indicator reading at 24 may be set to zero. Lamps 56 energized by the oscillator (38) give warning if the angular velocity of the barrel exceeds a preset level. The totalizer may be replaced by an electronic decoder and cold cathode display tubes. The motor 12 may be a direct current torque motor and the output shaft 16 may drive a selsyn transmitter to indicate via a selsyn receiver the angular displacement on an analogue meter. The apparatus may also be used for machine tools, radar or laser systems or a telescope. A less accurate version may be used for measuring roll of a ship, turn and bank of an aircraft or crane attitudes.

Abstract: 1,090,110. Electric-correspondence control systems. BROWN, BOVERI & CIE A.G. Nov.10, 1965 [March 6, 1965], No. 47593/65. Heading G1N. [Also in Division G3] Means are provided for the electrical control of variable-pitch propellers or rudders. In one arrangement a ship is driven by a variable-pitch propeller which is, coupled to two diesel engines, the main ship's generators also being driven from the propeller shaft for operation at constant speed. The pitch-angle is adjusted by an hydraulic power amplifier having control lever 6 coupled to servomotor 20. Alternating voltages from master transmitter 9 and follow-up transmitter 11 are applied to rectifiers 13, 14, which produce a D. C. signal representing the deviation of the lever 6 from a set position. This signal is fed to trigger circuit 15 for controlling relays 16, 17, selectively in accordance with the sense of the deviation. The relays are associated with thyristors 18, 19 in circuit with the motor 20 which is driven in either direction to correct any positional error of control lever 6. Tachometer generator 23 monitors the speed of the propeller shaft and provides a signal for trigger circuit 15 if the speed falls below the value selected by resistor 31 which is connected to controller 24. The speed-signal modifies the positional-error signal whereby the pitch-angle is reduced for restoring the speed of the propeller-shaft to the nominal value. The signal from the controller 24 is applied to the trigger circuit 15 alternatively through relays 25 or 26, and rectifiers 27 or 28, these relays being controlled by contacts 29, 30, which are activated when transmitter 9 is moved from a central position. The system may be modified for double-rudder control, the rudders being slightly offset when in the central position, and this offset being eliminated at greater rudder angles. In this arrangement, the tachometer generator 23 is replaced by a transmitter which supplies a direct voltage representing the rudder position. This signal modifies the signal representing the deviation between the desired and actual values of rudder angle.
