Title: Electrical power generating plant
IPC: F01D5/02
Filed: 1973-08-10
Abstract: 1443335 Rotary compressors and pumps; turbine plant SSS PATENTS Ltd 2 Aug 1974 [10 Aug 1973] 38092/73 Headings F1C F1G and F1T [Also in Division H2] A uni-directional power plant comprising a turbine 2, motor/generator 4 and a pump or compressor 7 has a synchronous toothed clutch 8 between motor/generator 4 and pump or compressor 7 arranged such that the clutch teeth interengage automatically when unit 4 tends to rotate in its normal direction of rotation relative to unit 7, or when the latter tends to rotate in a direction opposite to normal relative to unit 4, clutch 8 also being settable to a bi-directionally free condition such that when the plant is operating in the generating mode motor/generator 4 can be driven by turbine 2 without the latter driving pump or compressor 7. Clutch 8 is constructed as described in Specification 1291773 (see Division F2). The plant is used with air or water storage reservoirs, in the former case the motor/generator 4 being associated with a combustion gas turbine 2 and compressor 7 and in the latter with a hydraulic turbine and pump. When it is required to change from the generating to the compressing or pumping mode, motor/ generator 4 is disconnected from the mains and turbine 2 shut down. Compressor or pump 7 is then rotated at low speed in its normal direction by an auxiliary motor driving through reduction gearing 41, 42 and synchronous self-shifting clutch 43. When the speed of motor/generator 4 has decreased below that of unit 7, clutch 8 is shifted by servomotor 34 to the uni-directionally free ratcheting condition and the auxiliary motor is shut down. Turbine 2 is then operated to accelerate motor/ generator 4 via clutch 5, which may be identical to clutch 8, until it is in synchronism with unit 7 whereupon clutch 8 automatically engages so that turbine 2 can run unit 7 up to full speed. Motor/ generator 4 is then connected to the mains to operate as a motor, turbine 2 is shut down and clutch 5 disengages automatically. To change from the compressing or pumping to the generating mode, motor/generator 4 is disconnected from the mains whereas unit 7 is maintained in low speed rotation by the auxiliary motor. When the speed of motor/ generator 4 has fallen below that of unit 7, clutch 8 is set to the bi-directionally free condition, whereupon turbine 2 can drive motor/generator 4 through clutch 5 up to high speed without unit 7 being driven.

Abstract: 988, 757. Temperature sensitive substances. XEROX CORPORATION. Sept. 27, 1963 [Oct. 24, 1962],No. 38277/63. Heading G1D. [Also in Division G5] Portions of a thermotropically colour sensitive layer 21 are heated to produce a colour change and subsequently cooled to reverse the change. Conductors 12.. 19 form a lattice of Peltier junctions, whereby local heating and cooling will produce and erase a visible image. Layer 21 may be a 33.9% copper mercuric iodide, 66.1% silver mercuric iodide mixture in a methyl methacrylate binder. This mixture changes from yellow-orange to crimson at 70C. and must then be cooled to 10C. to reverse the change. Other materials suitable for layer 21 are copper mercuric iodide alone (70C. and 58C. are colour change temperatures), silver mercuric iodide (47C., 45C.), also bianthrone and its vinylene homolog, and members of the dianthrone and spiran series. Layer 21 may change in transparency rather than colour.

Title: Apparatus for separating pieces of solid material into fractions according to specific gravity
IPC: B04B1/00
Filed: 1957-12-13
Abstract: 854,855. Separating solid materials. STAMICARBON N. V. Dec. 13, 1957 [Dec. 14, 1956], No. 38918/57. Addition to 852,121. Class 117 In apparatus for separating pieces of solid material into fractions according to specific gravity, an annular bed of springs, Figs. 1 and 4, is held cantilever fashion on a fixed cylindrical wall 3. The springs are in vertical groups and arranged in closely spaced side-by-side relation. Material passes from a pipe 14 into a trough 13 mounted on a motor driven rotary shaft 9 and the pieces pass over a plate 15 to the upper ends of the springs. A cylindrical wall 4 is connected to the shaft 9 by arms 17 and is guided by rollers. A material collecting trough 18 with end walls 19, 20, Fig. 2, and separate compartments 22-24, is secured to the wall 4. The wall 19 lags behind the feed point 21, Fig. 2, and the time taken for an object to depress and to pass through the springs at the wall 4, which time is dependent on its specific gravity, will determine whether the object drops into the compartment 22, 23 or 24, i.e. the compartments will respectively receive fractions of the highest, medium and lowest specific gravities. From compartment 22 the heaviest objects pass to a trough 29 and conduit 37, the medium ones pass through an opening 30 to a trough 31 and conduit 38, and the lighter particles pass through opening 32, a trough 33 and a conduit 39. Similarly the feed may be separated into two or more than three fractions by providing a corresponding number of spaced collecting compartments. One or more fractions of the feed may discharge from within the bed of springs by providing an aperture or apertures in the rotary wall 4 at suitable levels. The wall 4 may be stationary in which case the collecting compartments are connected to the shaft 9 to ensure their rotation with the feed means. In a modification, Fig. 3, the feed means 12, 13 rotates faster than the collecting compartments beneath the bed of springs, and a reduction gearing is provided between the shaft 9 and the drive of the wall 4. The latter carries four curved guide blades 49-52 to aid the distribution of the feed over the springs. Specification 854,856 also is referred to.

Abstract: 1385099 Hydraulic control circuits COVENTRY CLIMAX ENGINES Ltd 19 July 1973 [25 Aug 1972] 39768/72 Heading F1P An industrial lift truck includes a control unit comprising actuators 12, 13, 14 which are used respectively for hoisting the forks along the mast uprights, and reaching and tilting the uprights on which the forks are mounted, a fourth actuator 11 being used for steering the truck, hydraulic fluid being fed to the said actuators by means of a pump 15 driven by a motor 26 which is adapted to drive the pump 15 at one of a predetermined selection of speeds, the speed of rotation of the motor 26 being detected by a speed sensor 27 which provides an output pulse to a pulse control unit 28 which in turn provides a feedback signal along a line 29 to a thyristor pulse unit 30 so that the motor 26 runs at a selected fixed speed. A control valve array 17 is disposed between the pump 15 and actuators 12, 13, 14 while a control valve 25 is disposed between pump 15 and actuator 11. A power steer potentiometer 31 is permanently coupled to the pulse control unit 28 which provides for minimum pump motor speed and thus a priority flow of pressurized fluid from pump 15 through a flow divider valve 22 and along a line 23 to the control valve 25 for the steering actuator 11 thus ensuring that power operated steering of the lift truck is always available. Located on the valve array 17 are levers 18, 19, 20 for controlling the other functions referred to above and when it is desired to operate one of the actuators 12, 13, 14, the corresponding lever 18, 19 or 20 is operated which causes a corresponding switch 35, 36 or 37 to be closed whereby the pulse control unit 28 increases the output frequency of the thyristor pulse unit 30 so increasing the pump motor speed and thus the output of the pump 15, the extra fluid passing from the flow divider valve 22 along a line 24 to the appropriate valve in the array 17 for the particular actuator 12, 13 or 14.
