Patent GB-916565-A (GB)
Title: Improvements in method of introducing fluidising gas into a heated fluidised bed
Inventor: BRITTAIN CHARLES PETER
IPC: B01J8/44
Filed: 1960-10-12
Abstract: A fluidizable bed of granular material is contained in a vessel having a perforated base, which base is separated from the fluidizable bed by a static layer of granular refractory material, the interstices of the static layer being such that the fluidizable bed, though resting on the static layer, shows no tendency to penetrate the static layer appreciably.  The static layer may be inhibited from being fluidized either by having a density and a particle size such that an ascending stream of gas is incapable of displacing it or by a mesh covering it.  The openings of the mesh permit contact between static layer and fluidizable bed.  In the examples (1) fluidizable aluminosilicate particles having a density of 28 lbs./ft3 and a mean diameter of 53 microns are supported on a static layer of silica sand particles having a density of 94,3 lbs./ft.3 and a diameter of 250-350 microns; (2) the silica sand of Example 1 is fluidized on a static layer of bauxite particles having a density of 106 lbs.ft.3 and a mean diameter of 1,000 microns; and (3) Al2O3 particles of density 65,1 lbs./ft.3 and diameter 50-100 microns are supported on a static layer of bauxite as used in Example 2.

Abstract: 1,213,448. Centrifugal pumps. SIEMENS A.G July 11, 1969 [July 13 1968 (2)], No.35178/69. Heading F1C. A pump comprises an impeller 1, an inlet 3 and an outlet 5 for liquid and a small port 7 which can communicate with the atmosphere and which is located within a zone 9 of the casing cover in which there will be created a positive pressure during forward running of the impeller and a negative pressure during reverse running, whereby air will be drawn into the pump during reverse rotation to prevent the pumping of liquid. The zone 9 extends from 15 degrees beyond the tongue 8 to 35 degrees ahead of it, relative to the normal direction of rotation. Within this zone, the port 7 may be located 25 degrees ahead of the tongue 8 and just within the impeller periphery, the best position being influenced by the tip curvature of the tongue. The port 7 can instead be located at the place where the volute 4 is narrowest or where the tangent to the volute wall is at the smallest angle to the radius r. A ridge (not shown) is provided adjacent the port 7 to deflect the flow into the port during forward running and away from the port during reverse running, thereby increasing the positive pressure and negative pressure respectively.

Abstract: 818,071. Automatic speed control. IGRANIC ELECTRIC CO. Ltd. Dec. 23, 1955 [Jan. 19, 1955], No. 36917/55. Class 38 (4). [Also in Group XXXVII] In a Ward-Leonard system the motor speed is regulated by a voltage which is the difference between a reference voltage representing a base speed and a second voltage representing the difference between the actual and desired speeds, the regulating voltage being used to control the generator or motor field current depending on its polarity and amplitude. In the embodiment described, the generator 16 has an armature 14 connected in series with the armature 12 of the motor 10. The field windings 20, 18 respectively are supplied from full-wave rectifiers 38, 32 respectively fed from the A.C. line L1, L2 through the power windings 24b, 24c and 22b, 22c of magnetic amplifiers 24, 22 and oppositelypoled pairs of rectifiers 34, 36 and 28, 30 respectively. The amplifiers 24, 22 have biasing windings 24a, 22a, respectively, fed from a full-wave rectifier 47 and control windings 24d, 22d, respectively. The D.C. control current in lines 52, 54, depending upon its polarity, flows through rectifier 48 and winding 22d to decrease the motor field current and increase motor speed or through rectifier 50 and winding 24d to decrease the generator field current and hence decrease the motor speed. The voltage responsible for the control current is the difference between a fixed reference voltage produced across resistance 56 by a current derived from a rectifier 60 fed by transformer 62 and the voltage produced across resistance 46 by the current from a rectifier 44 supplied from the output windings 26b, 26c of a third magnetic amplifier 26. The control winding 26d of the latter carries current depending upon the difference between a speed reference voltage, derived from rectifier 47 through a setting potentiometer 66, and a voltage representing the actual motor speed, from a tacho-generator 64. The biasing winding 26a of amplifier 26 is also supplied from rectifier 47. A negative feedback loop supplies a control winding 26e with a current representing the rate of change of armature current from a transformer 70 and another loop feeds a control winding 26f with a current representing the rate of change of motor speed and derived from the resistance 46 through a capacitance 72. In a modification, the motor speeds at which rectifiers 48, 50 start conducting are different, the windings 22d, 24d being returned to different tappings on the load resistors of rectifier 60, Fig. 4 (not shown).
