Title: Improvements in or relating to alternating current motor control systems
IPC: H02P27/02
Filed: 1944-12-19
Abstract: 598,063. Control of A.C. motors. WESTINGHOUSE ELECTRIC INTERNATIONAL CO. Dec. 19, 1944, No. 25474. Convention date, Feb. 29. [Class 38(iii)] [Also in Group XXXV] Balance-control means connected between an A.C. supply and a multiphase motor (e.g. a hoist motor) is arranged to unbalance the primary multiphase energisation of the motor substantially in accordance with motor speed. The unbalance may reverse the motor torque. Supply terminals L1 and L3 are connected to reactor network A1, B1, A2, B2; this bridge network is connected to terminals T1, T2 of the primary winding of the three-phase motor, and supply terminal L2 is connected to motor terminal T3, Figs. 2 and 6. The cores of the reactors can be saturated by coils 11, 12, and 21, 22. A generator PG driven by the motor opposes a potentiometer R4. If the motor speed exceeds the value of a selected tapping P1-P4 the rectifier V1 permits saturating current through coils 11, 12 to unbalance the bridge in a sense tending to slow down the motor; below this value the valve V2 permits current through coils 21, 22 to speed-up the motor. At correct speed the bridge is balanced and the vector diagram is as Fig. 3, VA1, VB1, VA2, VB2 being reactor voltages and E1, E2, E3 motor terminal voltages; the motor operates single-phase. When reactors B1, B2 are saturated the vector diagram is as Fig. 4 and a rotating field is produced. Saturation of reactors A1 and A2 reverses rotation of this field. The Specification as open to inspection under Sect. 91 describes also a complete system of controlling and braking a threephase slip-ring induction hoist motor, with a master controller for selecting the tappings on R4 and with a no-volt relay, a contactor for de-energising the generator PG for. fast-speed lowering, and contactors operable for connecting the motor directly to terminals L1, L2, and L3 during hoisting. This subject-matter does not appear in the Specification as accepted.

Abstract: 958, 629. Nuclear reactors. UNITED KING- DOM ATOMIC ENERGY AUTHORITY. Jan. 9, 1963 [July 5, 1962], No. 25787/62. Heading G6C. A nuclear reactor comprises a reactor vessel, a reactor core within the vessel, a flowpath within the reactor vessel for liquid reactor coolant, and non-return valves within the reactor vessel to counter a reversal of coolanf flow in the flowpath. In the boiling water reactor shown in the drawing, fuel elements (not shown) are housed in fuel tubes 12 through which pressurised water is circulated as a primary coolant. The fuel tubes 12 are situated in a region surrounded by a baffle 13 and contained between a pot 14 and a support plate 27; in a secondary coolant path water flows downwards between the pot and the baffle and upwardly through the core between the fuel tubes. A thermal shield 15 has apertures 16 to permit downward flow of the secondary coolant. The fuel tubes 12 are extended upwards by extension tubes 32 in a heat transfer region 31, and the tubes are interconnected at the top of extension tubes 32 and at the bottom of fuel tubes 12 to form ten parallel primary coolant paths. Primary coolant is collected from these paths by a ring header 35 and passes from these to three pumps 23 (of which only one is shown), to a helical toroid pressuriser 37, and thence back to the fuel and extension tubes. Secondary coolant passes upwards round the fuel and'pressurises tubes and boils; the steam and water is separated by cyclone steam separators 33 which discharge water to outlets 24 and steam to scrubber units 34 and steam outlet 19. Recirculated water of the secondary coolant, together with feed water, is returned to the reactor by inlets 25 and pass through about forty non-return valves 44 into the pot 14. The valves ensure that the pot 14 is not emptied if a rupture occurs at the inlets 25. The reactor core is moderated by the primary and secondary coolants and is shut down by hollow open-ended neutron absorbing rods 39 which are normally housed in the heat transfer region but may be lowered over guide tubes 42, the rods being hydraulically operated from a common fluid header 43.

Filed: 1955-09-12
Abstract: 807,897. Machining by spark discharge. FIRTH STERLING Inc. Sept. 12, 1955, No. 26031/55. Class 83 (4). In a method of and apparatus for machining a workpiece 5, particularly of tungsten carbide or hard alloy steel, by spark discharges, the discharge circuit is of low inductance. The apparatus is mounted on a pedestal 21-23 and includes means for maintaining a predetermined spark-gap between the workpiece 5 and a brass electrode 6. The latter are supported in a tank 29 of copper or steel lined with copper containing a dielectric 8 such as kerosene. Insulated posts 35 support a copper plate 34 on to which the workpiece is held by conductive clamps 36. An oil-filled metal-cased condenser 3, charged with direct current from a full-wave rectifier 11 and filter 2, Fig. 1 (not shown), is mounted below the plate 34 and its positive terminal is connected therewith by a strap 39 whilst the negative casing of the condenser is in contact with the tank which is connected with the electrode 6 by one or more flexible straps 40. The electrode may be rotated especially where used for cutting threads. The concentric arrangement of the electrode workpiece and condenser 3 within the tank, which forms the negative conductor of the discharge circuit, produces a low inductance thereof and thus increases the peak discharge current and the frequency of sparking. In a modification, Fig. 4 (not shown), the tank has a lid through which the electrode passes in sliding contact. In another modification, Fig. 5 (not shown), the condenser is disposed outside the tank and is connected thereto by a coaxial conductor. In a further embodiment, Fig. 6, a closed loop 65 is disposed adjacent the conductors 66, 67 and the electrode 6 for minimizing the discharge circuit inductance. The loop 65 is preferably insulated from the discharge conductors but may be electrically coupled thereto on one side only of the condenser 3, Figs. 7, 8 (not shown). The tank arrangement of Fig. 4 may be combined with a closed loop 70, Fig. 9 (not shown), or with a flat conducting sheet 74, Fig. 10 (not shown), serving the same function as the loop. A number of condensers 3 connected in series or parallel may be used instead of a single condenser.
