Filed: 1947-10-16
Abstract: 631,779. Automatic fluid-pressure control systems. BRITISH THOMSON-HOUSTON CO., Ltd., and BACHE, R. F. Oct. 16, 1947, No. 27766. [Class 38 (iv)] A mercury U-tube gauge provided with electrical contacts detects pressure variations in the delivery ducting of a blower or compressor and controls a reversible electric motor operating a discharge valve in the ducting. The gauge comprises a wide-bore tube 4, Fig. 2, connected at its upper end 6 to the point where the pressure is to be controlled, and mounted so that its height can be adjusted by screw 8. Its lower end is connected by rubber tubing 5 to a capillary tube t whose inclination to the horizontal is adjustable by rotation of the mounting 2. Three tungsten electrodes are sealed into wells formed in the bore of the tubing, the normal mercury level being between the top and middle electrodes. The control circuit comprises low-voltage relays 3, 4, Fig. 4, operated by D.C. from a transformer T and rectifier R, through the mercury gauge contacts. Contactors 1, 2 supplied from the A.C. mains L, N, under the control of relays 3, 4, operate contacts in the leads to the main and auxiliary motor terminals A1, A2 and Z1, Z2 respectively. When the lower electrode in tube t is connected to the centre electrode, only the motor is stationary, the circuit of contactor 2 being closed by contact 4a of energized relay 4, to open contacts 2b, c and d and close 2a in the circuit of contactor 1. At this time contactor 1 is unenergized, and all its contacts 1a ... 1d are open. If the pressure falls, relay 4, and hence contactor 2, are de-energized, contacts 2b, c and d are closed, and the motor operates in a direction to close the discharge valve. If the pressure rises, relays 3 and 4, and hence contactors 1 and 2, are all operated, contacts la ... 1d are all closed and contacts 2b ... 2d are open, and the motor operates in the reverse direction to open the discharge valve. For starting up, the manually-operated switch e energizes relays 3, 4, to open up the discharge valve before switching on the blower. The motor drives the valve through a reduction gearing and a flexible coupling by which limit switches f, g, hare operated to disconnect the motor in the extreme valve positions. When the blower is handling a gas other than air, the discharge from the valve may be connected to the inlet of the machine.

Title: Improvements relating to steam turbines
IPC: F22D1/28
Filed: 1922-10-13
Abstract: 208,841. Baumann, K., and Metropolitan-Vickers Electrical Co., Ltd. Oct. 13, 1922. Feed-water, heating.-To avoid dangerously high temperatures at the lowpressure end of a turbine when running under a light load, steam is withdrawn from the inlet end, or from a high or intermediate-pressure stage, and used for heat feed-water. A by-pass 5, Fig. 1, controlled by a valve 6, connects the steam inlet pipe 7 of the turbine 1 through the steam space of a surface-type heat-exchanger 8 with a circumferential belt 9, leading to a low-pressure stage. Another by-pass 10, controlled by a valve 11, connects two points beyond the extraction pump 4 in the condensate or feed-water pipe 12, controlled by a valve 11<a>, through the water space of the heat-exchanger 8, and a drain 17 connects the lower part of the steam space of the heat-exchanger 8 and the steam space of the condenser 3 In a modification, a heat-exchanger of the direct contact or jet type is used. Instead of being tapped from the inlet pipe, the steam may be withdrawn from a belt surrounding a high or intermediate pressure stage. Fig. 4 shows the invention applied to a turbine fitted with a progressive feed-water heating system, the feed-water under normal operation being passed through heaters 19, 18 and therein heated by steam tapped from belts 23, 22. By opening a valve 27 in a pipe 26, under light load conditions, steam from the intermediate-stage belt is passed through and cooled in the heaters 18, 19 and led by the pipe 21 to the low-pressure stage.

Filed: 1946-09-17
Abstract: 616,869. Agricultural implements. HORSTMANN, B. G. Sept. 17, 1946. Nos. 27864/46, 8969/47, and 24099/47. [Class 6 (i)] A tractor-drawn rotary cultivator, of the type having a transverse power-driven rotor, is characterised by the provision of mechanism adapted to utilize the rotor-drive power for lifting the rotor when the ground resistance exceeds a predetermined value. In one form, the cultivator comprises a rotor 1 supported at the rear end of a wheeled trailer 11 towed by a tractor, the rotor being driven from the tractor power takeoff through a shaft 31 and a differential gear 16 driving a transverse shaft 17 from each end of which chain drives 22 pass to the rotor. The differential gear includes a third element connected to a shaft 25 which carries links 26, 29, the lower end of the link 29 being connected to the axle 14 of the ground wheels 12. In the event of obstruction of the main drive, the drive is transmitted to the shaft 25 through the third element of the gear, thereby lowering the wheels 12 and raising the rotor. In another construction, Fig. 5, the rotor is carried by arms 32 pivoted to fixed extensions 33 on the tractor chassis. The rotor is driven by gearing 37, on a transverse layshaft 39 mounted between the ends of bellcranks 35 pivoted about the axle 2 of the rotor. The other ends of the bell-cranks are connected to the tractor chassis bv a link 45. In the event of obstruction, the gear 37 will tend to rotate epicyclically about the gear 38 on the rotor axle thus lifting the pivoted arms. In a further modification, Fig, 7, the belt-crank 35 carries a jockey sprocket 51 which bears against a chain transmission between a layshaft 54 and the rotor. Obstruction of the rotor causes tightening of the chain and rocking of the bell-crank which raises the implement.

IPC: B29C49/68
Filed: 1965-07-01
Abstract: 1,110,703. Blow-moulding articles of stress crack-prone plastic. DOW CHEMICAL CO. 1 July, 1965 [8 July, 1964], No. 27946/65. Heading B5A. In a blow-moulding process, the parison may be preformed or injected or impacted on a mandrel. Articles of stress crack-prone plastics, e.g. polystyrene are produced by forming the parison of the plastics in which the molecules have a high degree of multiaxial orientation, placing it on a mandrel having blowing means, inserting in a blow-mould and blowing the parison at 110-140 C. The parison may be formed on the mandrel and blown while still hot from the forming step, or allowed to cool, placed on a mandrel having heating and blowing means, rapidly heated thereby before blowing to a temperature high enough to enable blowing but not too high to cause relaxation of the orientation of the molecules in the parison. The required orientation is obtained by rotating one of the die elements past the fill point of the die cavity, i.e. the stage when the desired amount of material has been added while forming the parison by injection-moulding, or in impact moulding by rotating one of the die elements during and after the impact stroke while the plastic solidifies. A torque of 750- 2200 1b. may be applied while forming the parison. The apparatus may comprise a mould having a cavity of the desired shape, a mandrel for receiving the parison, the mould having an opening to receive the mandrel and parison and the mandrel having means to heat and blow the parison. These means preferably controllably heat the mandrel wall and thereby the inside of the parison, and an oven, having an orifice to fit the mandrel and parison, may be used to radiantly heat the outside of the parison, e.g. by passing an electric current through resistance wire wound around a tubular support, concentric with the mandrel. Such heating will avoid relaxation of the molecular orientation. There may be a plurality of these ovens mounted on a table support, with a parison supply station and a blow-moulding station, and a plurality of mandrels mounted on a vertically movable turntable to grasp parisons from supply, reheat in the ovens, and mould them by blowing.
