Title: Method of manufacturing keene's cement
IPC: C04B11/024
Filed: 1934-06-23
Abstract: In the manufacture of Keene's cement from calcined calcium sulphate containing iron as an impurity, the iron is converted into a colourless salt by treatment with a suitable reagent such as ammonium sulphate, ammonium arsenate, ammonium phosphate, phosphoric acid or sulphuric acid.  1-3 per cent of the reagent may be added to the hydrated calcium sulphate before calcination. When temperatures in excess of 800 DEG  C. are employed, however, the reagent is not added until after calcination, in order to prevent re-formation of red iron oxide; the hot mass is rapidly cooled by the addition.  The calcium sulphate employed may be that obtained as a by-product in the production of superphosphates by treatment of phosphate rocks with sulphuric acid.  Iron may be present as an impurity in the rocks or may enter during the treatment.  Residual phosphoric and sulphuric acids present in the by-product calcium sulphate may be removed by neutralization or washing; this is unnecessary when calcination is effected at the higher temperatures.  The cement composition is completed by the addition of an accelerator such as 2 per cent of potassium alum or a mixture of 1 per cent of aluminium sulphate and 1 per cent of potassium sulphate.

As described, the ring 8 has central hole 11 and rims 26 joined by radial bars 9, Fig. 2 (not shown), with the spaces spanned by sieve plates. Outlet openings 13 are made in the mill shell around the area closed by the ring 8, and this part of the mill is surrounded by a casing 14 having a slurry outlet 15. There are provided lifters 7 in the internal wall of the mill, lifters 17 on the side of the ring facing the inlet and lifters 22 on the end face 21. In operation, water is introduced via a pipe 4 and additional water through a trunnion 19 by a pipe 27. Solid materials are washed and partially ground in the first compartment to form a slurry, adequately fine material passing through the sieves 10 into the outlet channel constituted by the interior 12 of the ring, and thence to the outlet 15. Coarser material passes through the ring into the compartment 16 and is autogeneously ground and freed of all washable particles. The fluidity of the slurry is increased by additional water supplied by the pipe 27 and passes out of the compartment via the sieves in the ring 8. The material resistant to grinding passes from the mill by an outlet trunnion 19. Where the mill is provided with several compartments, more than one hollow ring may be used to provide adequate outlet for the slurry.

Abstract: 785,451. Washing granular materials. WESTFALIA DINNENDAHL GROPPEL AKT.-GES. July 1, 1954 [July 6, 1953], No. 19295/54: Class 82(2) A method of separating minerals into three or more fractions comprises feeding the minerals into a jig containing a liquid of specific gravity greater than the lightest fraction but less than the next heavier, the light floating fraction being dicharged by overflow or a scoop wheel, the heavier material being separated on the jig bed, and the top of the layer on the bed being kept .clear of the bottom of the floating layer. As shown, the bottom of a jig is divided into two by a wall 10, and at the top of each part is a screen 2 or 2a. In the case of separating coal, the liquid used has a specific gravity greater than that of the coal but less than that of the middlings; the coal therefore floats and is removed by a scoop wheel 3 whilst the middlings and shale sink on to screens where separation into two products takes place, the middlings being discharged over a weir 6 and the shale below the weir on to a conveyer 8 having a division to keep the products separate. The screen 2a may be hinged to control discharge of shale. The distance of the top of the layer on the screen from the bottom of the float should be at least 300 mm. An intermediate separation of shale may be made by extending the division 10 above the screens. Further intermediate products may be taken off in similar manner by the provision of additional plates 10.

Title: Low-pressure cut-off valves
Inventor: HUTTON ARTHUR LESLIE
IPC: F16K17/00
Filed: 1953-07-07
Abstract: 723,163. Fluid-pressure servomotor-control systems; fluid-actuated valves. SOUTH EASTERN GAS BOARD. July 7, 1953 [July 30, 1952], No. 19323/52. Class 135. In a low-pressure cut-off valve, e.g. for gas burning appliances, inlet pressure at 14 acts on one side of a closing diaphragm 24 connected to a valve 29 and on one side of a holding diaphragm 16 also connected to the valve to exert a holding force on the valve in its closed position, the other side of the diaphragm 16 communicating with the valve outlet. As shown, with the valve held open by inlet pressure acting on the diaphragm 24 which is weighted at 28, gas passes from the supply 36 through the cut-off valve 37, a valve 38 controlled by a flame failure pilot device 40 and a valve 39, actuated by a thermostat 41 controlled by a thermal element 42 in the appliance, to a pressure-sensitive actuator 43 regulating a main control valve 44 in the line 36 leading to a burner cock 46 and burner 45. A valve 48 connected to the diaphragm 16 is closed when the valve 29 is open so that the pressure in the outlet chamber 15 acts via passage 19 in the chamber 18 beneath the diaphragm 16 and pressure balances it. When the gas pressure fails, the valve 29 closes and the valve 48 opens so that gas in the pipe leading to the actuator 43 passes to atmosphere via 19, 18, 50, 36 and the burner. The valve 44 closes and the unbalanced inlet pressure on diaphragm 16 forces valve 29 on its seat 30. The valve is reopened by closing the cock 46 and opening a valve 22 allowing pressure to build up in the outlet via a weep passage 21. If the valve 37 is situated in the pipe 36, the valve 48 and pipe 50 are dispensed with. In a modification, a ported cylindrical valve closing on a spherical seat is carried by the two diaphragms, the diaphragm 24 being the smaller of the two, the inlet leads in between the diaphragms and the outlet leads out beneath the diaphragm 16, while a screwed needle valve controls a weep passage through the seat.

Title: Improvements relating to brush-shifting means for electric motors
IPC: H02P1/24
Filed: 1951-08-16
Abstract: 703,869. Dynamo-electric machines. BRITISH THOMSON-HOUSTON CO, Ltd. Aug. 16, 1951 [Aug. 22, 1950], No. 19363/51. Class 35. [Also in Group XXXVIII] Relates to a three-phase commutator motor 6 of the Schrage type for driving a printing press and having its brushes shifted by means of a reversible pilot motor 13. A push-button 40 is actuated to energize relay 12 for starting the motor 6, and, assuming that the brushes are in an appropriate position, tire motor operates at a low speed. To increase the speed a knob 23 is adjusted to the desired setting on dial 22 so turning a disc 27. A sun gear 28 is coupled to the pilot motor 13 and is held stationary, so that, as the disc 27 is rotated, planet gears 31, 32, which are mounted on a pin 27a on the disc 27, are rotated about the pin. The planet gear 31 drives an internal gear 33 which has a cam part 33a, rotation of the gear 33 in the clockwise direction causine the cam 33a to close contacts 35a so energizing the pilot motor through its field winding 13a. The brushes of the motor 6 are thereby moved to the desired position, and the sun gear 28 now drives the internal gear 33 back towards its neutral position. As the cam 33a approaches this position finger 36 opens contacts 37 and resistor 38 is placed in series with the pilot motor. When the cam reaches its neutral position contacts 35a are opened and the pilot motor is de-energized. In the event of a paper jam, or if the paper supply is exhausted, a tripping device 2, which is responsive to the thickness of the paper, actuates its contacts 2a, 2b, and the pilot motor is energized through its field winding 13b. The brushes are then driven to a low-speed position until a limit switch 47 operates to stop the pilot motor. Manual re-setting of the trip device 2 again actuates the contacts 2a, 2b, to re-energize the pilot motor and return the brushes to their former position. Reduction of the speed of the motor 6 while the press is in operation is effected by changing the setting of the knob 23, contacts 34a being closed to energize the pilot motor through its field winding 13b until the cam 33a is returned to its neutral position. A stop button 49 de-energizes the relay 12 to disconnect the motor 6 and drive the brushes back to their neutral position. The motor 6 can be inched by opening switch 39 and closing switch 40 for short intervals, contacts 406 preventing the pilot motor from changing the brush position during this operation. In order to clean the rollers of the press the knob 23 is set to the full-speed position and the pushbutton 50 is actuated to open contacts 50a and close contacts 50b. When the push-button 50 is released the trip device 2 operates to return the brushes to the low-speed position.
