Patent GB-1513571-A (GB)
Title: Process and apparatus for activating or reactivating carbon particles in a fluidized bed
IPC: C01B31/08
Filed: 1975-04-21
Abstract: For the purpose of activation or reactivation, coal particles are continuously passed from a conveying device (2, 3, 4, 5) into a fluidised bed (8). The fluidised bed (8) is located above a screen (1). A hot gas laden with water vapour is generated by means of a burner device (9, 11, 12) and injected into the fluidised bed (8) through the screen (1). Associated with the fluidised bed (8) there is an overflow (6) via which the coal particles are discharged. The overflow (6) determines the height of the fluidised bed, the screen (1) determining the width and length of the fluidised bed. The fluidised-bed height is at most 12 cm, preferably from 3 to 7 cm, and the fluidised-bed length is four times the fluidised-bed width. In a fluidised bed having these dimensions, the coal particles have a vertical velocity component sufficiently large for good mixing, but only a minimal horizontal velocity component, so that all the coal particles on average reside for virtually the same length of time in the fluidised bed and adopt the same mean temperature. As a result, uniform activation or reactivation is achieved. <IMAGE>

Title: Automatic control for liquid cooled air compressors
IPC: F04B49/02
Filed: 1943-10-13
Abstract: 570,893. Controlling cooled compressors. MONROE, R. O., and CLAYTON, W. F. Oct. 13, 1943, No. 16814. [Class 8 (i)] The cooling water conduit of a compressor contains a valve opened by fall of the air pressure; the compressor starting means is actuated by the flow of water. Water is supplied from a conduit 20 past a solenoidal valve 22 associated with a valved by-pass 27 to the after-cooler 5 and thence to the jacket of the compressor 1 and so to a drain connection 30. The air is delivered through the after-cooler and a separator 7 to a reservoir 9 fitted with a relief valve and a pressure-responsive switch 15 which on fall of pressure to a due level closes a circuit between the supply mains 32, and operates the solenoid to open the valve 22. The circuit also includes the primary of a transformer 37, the secondary of which is connected with a relay switch 43 in the starting circuit and to an electrode 29 in a fitting 25 at a high part of the water flow, the circuit being completed by the flow of water sinking the electrode; when this occurs, the relay contact 43 is made and the motor starter 34 operated; if the water supply fails, the liquid contact with the electrode is broken by drainage of water away from the fitting, and the current ceasing allows the relay contact 43 to open, and to open the starting contacts 34. If the pressure rises to a fixed point, the contact 15 is opened and the valve 22 closes and the motor is again stopped.

Abstract: 947,363. Spark-erosion. ELOX CORPORATION OF MICHIGAN. May 9, 1961, No. 16873/61. Heading B3V. [Also in Division H3] A spark erosion apparatus has means for applying to the spark gap for initiating a spark discharge, a voltage higher than that necessary to maintain the spark during machining. The gap 21, Fig. 1, between electrode 24 and workpiece 28 is bathed in a dielectric coolant and supplied with normal spark pulses of high power through rectifier 26 from transformer secondary 18. A further secondary winding 19 supplies higher voltage low power pulses through rectifier 23 and resistor 25. Once the spark has been established the current build-up will load resistor 25 and render winding 19 ineffective. The transformer primary 14, damped by network 100, 102, 104, is fed with current from source 10 through an electronic switch comprising a bank of parallel tubes 22 which are triggered by a vibrator network consisting of pentodes 36, 38 and one or more pentode amplifiers 66, 76, whose anodes are fed from source 44 which may be separate or derived from source 10. A diode 80 ensures positive cut-off characteristics. To stop the apparatus in the event of a short-circuit in the gap, the latter is connected through resistor 126 across the primary of transformer 122 whose secondary controls the grid 108 of tube 106. The anode of this valve is connected through line 107 with the grid circuit of pentode 38 which stops the vibration immediately tube 106 conducts due to a short circuit in the gap. In a modification, Fig. 11 (not shown), an inductor and resistor are in series with rectifier 26 and a capacitor is connected across resistor 25. In another embodiment, Fig. 8 (not shown), a voltagedoubling circuit utilizing a flyback voltage stored across a capacitor is used to produce a high voltage impulse for initiating the spark; a push-pull transformer fed with alternating current may be used to supply the spark gap. In a further embodiment, Fig. 9, the gap between workpiece 200 and electrode 202 is fed with normal spark machining pulses from an alternating supply 208, 210 through transformer 204, rectifier 214 and resistance bank 220 controlled by switches 222. High voltage striking pulses are fed from transformer 264 through diodes 268. The transformer primary is fed from rectifier 224 through capacitor 260, choke 262 and thyratron 256 whose grid is fed with pulses from saturable transformer 252. In another embodiment, Fig. 10, banks of transistors 306 are used instead of tubes and are controlled by a multivibrator 336 to deliver pulses of high current to the electrode 302. High voltage triggering pulses are derived from a step-up transformer 358 controlled by transistors.

Title: Improvements in and relating to variable speed gearing
IPC: F16H3/36
Filed: 1923-06-29
Abstract: 222,920. Wylie, R. W. R., Sheppard, S. D., and Davidson, E. J. June 29, 1923. Variable-speed gearing comprises a number of toothed wheels 7 loose on a countershaft 5 with their rims on the surface of a cone and adapted to be engaged alternatively by a pinion 23 slidably splined on a driven shaft 20. The individual cone gears are connected by clutch dogs 13 on both faces, which are normally pressed by spring 12 into engagement to lock the cone solid. A gear 4 constantly driven from a pinion 3 on a driving-gear 2 is normally connected by multiple-plate clutch 10 to the extended hub of the nearest gear 7. The pinion 23 has spur teeth and the cone gears 7 are cut with the same cutter to have the spaces between the teeth with parallel side as shown in Fig. 3. The resulting teeth on the cone gears are then corrected as shown in Fig. 2 by cutting away part of the face and flank from a maximum at the large diameter end and from a maximum at the crown and root to nothing at the pitch line. The connection may be applied to the teeth of the pinion 23. Prior to a speed change, the clutch 10 is disengaged and cone wheels 7 freed by applying thrust to a rod 15 passing through the shaft 5. This is done by moving an operating- lever 17 with a swell 16 to the left of Fig. 1. Subsequent movement of the lever 17 perpendicular to the plane of the paper slides the pinion 23 to its new position through toothed gearing 33, 34 and a screwed rod 25. A direct high-speed drive is obtained, through a clutch 26. Reversed driving is obtained through an idler 31.

Abstract: 567,515. Reciprocating pumps. STRUCKMAN, E. Oct. 18, 1943, No. 17077. [Class 102 (i)] [Also in Group II] A bolt for the lid of a hydroextractor 1, or other centrifugal machine, is held in locking posi.- tion hydraulically by means of a diaphragm pump 22 driven from the main pulley 38 through pulleys 39, 40 and a belt 41. The rotating cage 2 is driven by belting through a spindle 4, and has a lid 5. A locking bar 8 in bear.- ings 7 on the lid has a flat end portion 9 which, when the bar is rotated to the unlocked position, is vertical and may pass through a slot 10 in a bracket 11 when the lid is raised. A hand wheel 15 and stub-shaft are used to rotate the bar 8. Fig. 6 shows the locking position with a bolt 12 forced upwards into a recess 18 in the shaft by liquid pressure under a diaphragm 19. The diaphragm pump 22 is operated by a crank 26. Liquid passes from a tank 30 through an inlet valve 33 and is discharged past a valve 34 into a pipe 35 leading to a casing 21 which is lower than the tank 30. Liquid may be bled continuously from the space below the diaphragm 19 through a needle valve 37 so that when the pump action ceases, the liquid below 19 is slowly forced out by the spring 17 and thus retracts the bolt 12. Fast and loose pulleys 45, 46, for driving the machine, are shifted by striking gear 47. To prevent the cage being run with the lid open, the striking gear is prevented from moving by a plate 48 fixed to the side of the bar 8. This plate is vertical when the portion 9 is in the unlocked position as shown at B, Fig. 3. With 9 locked, A, Fig. 3, the plate 48 is clear of the striking gear.
