Title: Mine roof support remote control systems
Inventor: KIBBLE JOHN DUNBAR
IPC: E21D23/16
Filed: 1963-03-08
Abstract: 1,065,881. Hydraulic apparatus. COAL INDUSTRY (PATENTS) Ltd. March 6, 1964 [March 8, 1963], No.9326/63. Heading F1P. A plurality of hydraulic advancing mine roof support units are arranged in at least two groups (2 - - 6), (7, 8 and 1) Fig.1 (not shown) and the units of each group are advanced in a predetermined sequence, units (2, 7) being master units which on receiving a signal from a remote control point serve to initiate the advancing sequence and the system also includes means for producing a signal at the control point indicating completion of the sequence of operations. Each unit other than the master unit comprises a ram (64) Fig. 3 (not shown) which advances the prop frame (22a) when pressure fluid from a supply line (26) is admitted to the pulling end of the ram cylinder through a control valve (60) when the latter is opened by pilot pressure transmitted to a chamber (60a) through a line 28 leading from a solenoid operated valve 25 of the master unit or through a line from the previously actuated unit. The outlet of control valve (60) also leads to a pilot chamber (20a) to open a normally closed prop release control valve (20) located between the prop frame (63a) and a return line (29). On completion of the prop unit advance a trigger valve (68) serves to pressurize a pilot chamber (20b) thereby closing valve (70) and also supplying pressure to the props to re-set the same. The resulting pressure rise then opens a trip valve (80) and pressure is transmitted along a line (67) to initiate advance of the succeeding unit. The master unit is the last of the group to be actuated when pilot pressure is transmitted to chamber (30a) Fig. 2 of the ram control valve (30) which is thereby opened to connect supply line (26) to a line (31) leading to the pulling side of ram (24) and leading to the pilot chamber (40a) of the prop release valve (40) which acts as does valve (70) of the remaining units. Ram control valve (30) also has a pilot chamber (30b) which on energizing a solenoid valve (23) is connected to supply line (26) resulting in opening of valve (30) and connecting line (26) to a line (32) leading to the conveyer pushing side of the ram (24). An abutment (37) on the ram and a pressure switch operated after resetting the props send signals to the remote control point. In a modification each master unit selectively controls the sequence of its own group or of the units of an adjacent group.

Title: Improvements in or relating to gas-turbine plants
IPC: F02C9/24
Filed: 1944-05-17
Abstract: 580,271. Gas turbines. SULZER FRERES SOC. ANON. May 17, 1944, No. 9446. Convention date, May 18, 1943. [Class 110 (iii)] A gas turbine plant having a part, or all, of the working fluid circulating around a closed circuit, is regulated by means of a speed governor 24 which either admits additional fluid at high pressure to the circuit from an accumulator 9, or opens a bye-pass valve 21 placed between high-pressure and low-pressure turbines 6, 7. The bye-pass pipe 20 is preferably connected to the same point 12 to which the pressure supply pipe 10 is connected. The accumulator 9 is supplied by a compressor 18 driven by a motor 19. Low and high pressure compressors 1, 3, having an intercooler 2, lead air through a pre-heater 4 to a heater 5, thence to the turbines 6, 7. Exhaust air from the latter flows through 4, a cooler 8, and returns to the compressor 1. Fuel is supplied through a valve 33 and combustion air by a blower 31. Further supplies to the circuit may be made through pipes 14. 15, controlled by valves 16, 17 influenced by the governor 24. Valve 11 or 21 is fully opened before the valves 16, 17 or leak-off valves 34, 35, also influenced by the governor, are fully opened, valves 11 and 21 opening more rapidly than the other valves. Fig. 2 shows a modified plant in which part of the air supplied by a compressor 40, after passing through a pre-heater 41, is used as combustion air in a combustion chamber 42. The second part of the air is heated in a coil C and led to an air-driven turbine 43. The combustion gases from 42 drive a turbine 45 and are exhausted to atmosphere, or to heatexchangers. A cooler 44 is provided. An accumulator 47 is supplied with air by a compressor 57. A regulating valve 49 is opened to admit compressed air to an intermediate stage of the turbine 43, when the speed of a governor 55a falls. When the load diminishes, the governor speeds up and opens a bye-pass valve 50 so that the latter stages of turbine 43 receive less working fluid than the earlier stages. Further control is secured by a compressor 46 which, at maximum plant load, supplies all of its air to the turbine circuit. Under influence of the governor 55a, regulating valves 62, 63, 64 are opened successively to release a graduallyincreasing quantity of air from the compressor 46.

Filed: 1949-04-07
Abstract: 664,539. Gear-grinding. SYKES, Ltd., W. E. March 23, 1950 [April 7, 1949], No. 9479/49. Class 83 (iii). [Also in Group XXIII] A gear grinding machine comprises a helically-ribbed grinding- wheel, means for rotating a workpiece, and means for imparting simultaneous and co-ordinated relative motions to the wheel and work, both in the direction of the work axis and also for either increasing or .diminishing the distance between their axes. The helically-ribbed grinding-wheel 4 is rotated by a motor 24 which also rotates the conical blank 28 via differential gearing 64, change gearing 68, shafts 71; 62 and a driver 54. The work is mounted on a slide 34 which is fed past the wheel by a screw 42 which is also rotated by the motor. 24 through shafts 46, 49, 52 and 76, change-gearing 75 and the shaft 71. The slide 34 is mounted on a head 36 rotatable on a boss 37 so that helical or plain spur teeth may be produced. If helical teeth are required, the differential 64 adds the necessary compensatory motion through change gearing 87, which is normally disconnected. To produce conical forms, the hob, which is mounted on a slide 7, is fed to or from the wheel by a screw 26 rotated through change gearing 82 and the shaft 76. Clutches 96 and 93 are provided for disengaging the wheel and work drives for manual setting-up. It is stated that the co-ordinated motions may be obtained, alternatively, by sine-bars &c., or interconnected electric motors. Furthermore, the work may be stationary and the wheel moved, or the slide for the grinding-wheel inclined, or the work set at an inclination to the wheel slide-ways. If barrel-shaped gears are to be produced, the gearing 82 may be suitably modified.

Filed: 1973-02-27
Abstract: 1385865 Fishing device J B PENA 27 Feb 1973 [28 Feb 1972] 9500/73 Heading A1A A power driven float for carrying two sets of fishing gear from the shore includes a clockwork device to release the gear from spring loaded tubes and also to turn off the engine. The float is recovered by a line attached to the stern. The gear is packed in cylinders 4 attached to springs within projector tubes 42 mounted across the float at the rear and each cylinder is held in the loaded condition by a rocker arm and pawl. The clockwork device 2 has a shaft 6 driven by clockspring 8 with the unwind speed limited by the pinion meshing with gearwheel 5. On release, the shaft rotates the cam 17 whose face releases in turn each of the pawls to allow the fishing gear to be ejected. The shaft is then accelerated over the sector 7 of the gearwheel 5 with missing teeth until finger 9 rocks arm 10 to rotate shaft 11 and cam 66. This permits the spring loaded fingers 67 to rotate and to close the rotary valves 64 attached thereto, thereby closing off the inlet and exhaust connections and stopping the engine. The cam 17 has a pivotted blade 27 with a ramp on the underside which allows it to ride over the pawls 18 against leaf spring 41 when the clockspring is being wound with key 13. The propeller has vanes each of which is free to move into the working position by reaction with the water when driven but is spring loaded into a plane containing the axis of propeller rotation to minimise the reverse towing force during recovery. The engine 12 is supported in a cradle for ease of removal and is accessible past hinged cover 61. Also hinged along the same axis are the inlet and exhaust tubes 55 which are held in the raised position by spring 59 but can be lowered after releasing the spring at 60. An elbow 57 at the end of the inlet tube can be rotated away from the direction of the wind.

Title: Improvements in apparatus for echo-sounding by means of radio oscillations
IPC: G01S13/12
Filed: 1940-06-04
Abstract: 600,652. Radiolocation. GENERAL ELECTRIC CO., Ltd., and ESPLEY, D. C. June 4, 1940, No. 9740. [Class 40 (vii)] In echo-sounding apparatus in which pulses of radio oscillations are transmitted and received after reflection, the receiver includes a filter, the band width of which is varied concurrently with and in the opposite sense to the length of the transmitted pulse. A cathoderay tube 1 has one pair of plates 3 connected to a time-base 6 the frequency of which is determined by an oscillator 7. The receiving aerial 10 is connected through an amplifier 8 and band-pass filter 9 to the other pair of plates 4. The screen 5 of the tube 1 is pierced by a slit 11 behind which is a collector 12 connected to the generator 13 that feeds the transmitting aerial 14. The collector 12 receives current only when the cathode ray is passing over the slit, and then applies bias to a valve of the generator 13 which opposes a bias normally applied to paralyse the generator and a pulse is emitted of a duration dependent on the speed of traverse of the ray. The oscillator 7 is connected to the filter 9 so that the width of the transmission band of the filter decreases as the speed of the traverse decreases and the duration of the pulse increases. The connection between the oscillator 7 and filter 9 may be effected by ganging variable condensers or inductors or by applying related biasses to valves. The oscillator 7 may also be similarly connected to the amplifier 8 so that the gain of the amplifier increases with decrease of the speed of traverse of the ray. The sensitivity is thereby increased for measuring large distances.
