Title: Improvements in or relating to electric motor control systems
IPC: H02P1/34
Filed: 1926-01-29
Abstract: 266,518. Carpenter, C. E. Jan. 29, 1926. Fluid actuation.-In a motor starting and controlling system, a pump 11 driven by the controlled motor circulates fluid through a restricted passage 44 and on the attainment of a given speed lifts a valve 20 which restricts the flow and therefore increases the pressure. A Bourdon tube 17 or other pressure-responsive device is thus caused to switch over an electric contactmember 60 of a two-way switch 65, 66 for the purpose of making the required changes of the motor connections in starting &c. A converse action of the switch due to fall of pressure takes place when the motor is slowing down. In modified apparatus the Bourdon tube is replaced by a cylinder and piston, devices are added for adjusting the travel of the check-valve or the check-valve is replaced by an adjustable needlevalve.

Title: Improvements in and relating to regenerative braking arrangements employing grid controlled discharge devices
IPC: H02M7/00
Filed: 1935-01-28
Abstract: 433,424. Converting. BRITISH THOMSON-HOUSTON CO., Ltd., Crown House, Aldwych, London. Jan. 28, 1935, No. 2779. Convention date, Jan. 26, 1934. [Class 38 (ii)] [See also Group XXXVII] In an arrangement in which a motor is supplied from an A.C. circuit through a discharge device and provision is made for regenerative braking by reversing the discharge device connections so that it operates as an inverter, the voltage characteristic of the machine when operating as a generator is modified so that at all currents above a nominal value the output voltage is below the value permissible for inverter working. For example, resistance may be switched into circuit so that the generator characteristic e, Fig. 1, intersects the inverter characteristic c at a nominal current of Jo. In addition, the voltage difference at currents below this is absorbed by means such as a choke connected in the D.C. circuit, the design of such a choke being discussed in the Specification. In the arrangement shown in Fig. 3 the series motor 1 is converted to a shunt type generator during regeneration by means of an exciter 15 which, to give the machine a characteristic as at f, Fig. 1, is provided with an opposing series field winding 17 mounted on an auxiliary pole which saturates at a fairly low value of current so that the voltage only drops rapidly during the low values of current. With this arrangement a choke 18 is switched in during regeneration. In a modification of this the shunt and opposing field windings may be mounted on the motor 1.

Abstract: 589,644. Relief valves. JACK & HEINTZ, Inc. Feb. 16, 1944, No. 2890. Convention date, Dec. 23, 1942. [Class 135] A pressure relief valve for fluid pressure lines comprises a casing 1 having a permanently open main conduit 3 connected in the line and also a pressure relief outlet 35, the latter being under the control of an auxiliary valve 11 which normally operates to connect a byepass conduit 22 fed through a restricted passage 20 from the main conduit with one side of the main valve, but which, when pressure in the main conduit becomes abnormal, moves to disconnect this side of the main valve from the byepass conduit and connect the latter with the other side of the main valve for moving the latter to its open position. The main valve comprises integrally connected spaced pistons 6, 7 and is loaded by a spring 8 in a chamber 28 to abut an adjustable stop 9 in a chamber 5. The auxiliary valve plunger 11 has four pistons 12, 13, 14, 15 and is loaded by a spring 16 adjustable by a knob 18. The byepass conduit 22 normally communicates with the chamber 28 by a port 25, an annular space 26 and a passage 27. When pressure becomes abnormal, the auxiliary valve is moved to the left by the pressure on its end in an extension 24 of the byepass conduit. The port 25 is immediately closed and then the piston 14 uncovers a port 36 so that the chamber 28 is vented via the port 27, the annular passage 26, the port 36 and the port 35. Simultaneously, pressure fluid is admitted to the chamber 5 via a port 29, annular spaces 10 and 30, and a port 31. When the main valve has moved so far to the left, the port 35 is connected to the main conduit 3 and thereafter the chamber 5 is vented through passages 33, 34 and both valves return to the normal position shown.

Title: Improvements relating to methods of combustion of liquid fuel and apparatus therefor
IPC: F23C99/00
Filed: 1959-01-27
Abstract: 902,894. Vapour burners. FRASER, R. P. Jan. 27, 1959, No. 2990/59. Class 75 (1). [Also in Group XII] Atomized liquid fuel mixed with steam is injected continuously into a gasefication chamber and discharged as a gas into a combustion chamber where it is burnt with atmospheric oxygen so that the flame passes over and around the gasefication chamber. In one embodiment, Fig. 1, the mixture of fuel and air is injected into the gasefication chamber through a nozzle 5, entraining an amount of air less than that required for complete combustion through a passage 4. The remaining combustion air enters the flame tube 2 through holes 10, and part of the flame is drawn backwards over the gasefication chamber by induction through passages 9. In a modification, Fig. 2, the fuel and steam is injected through nozzles 32 into gasefication ducts 33 arranged within a flame tube as described in Specification 902,893. The mixture of fuel and steam is produced by passing water to the surface of a liquid 16 of high boiling-point initially heated by an electric element 17. Fuel passes through a coil 18 heated by the rising steam to a mixing chamber 19 with a steam inlet 23. The liquid 16 may be kept hot by circulation through a pipe 53 encircling the flame tube. The steam raising chamber may be separate from and communicate with a chamber containing the fuel supply coil and mixing chamber. In another embodiment, Fig. 4, steam is fed to a chamber 27 with a perforated end wall 28 spaced from the perforated end wall 26 of a chamber 25 supplied with fuel under pressure. The space between the walls 28, 26 forms a mixing chamber, and the atomized fuel and steam is fed through a jacket surrounding the steam chamber to the gasefication chamber. Sinuous gasefication tubes may be used, Fig. 9, not shown.

Abstract: 871,803. Slip couplings ; overload release clutches; shafts. BIRFIELD ENGINEERING Ltd. Jan. 30, 1959 [Jan. 30, 1958], No. 3036/58. Class 80 (2). An overload slip coupling for a power takeoff shaft used in an agricultural tractor or the like connects the forks 3, 4 of two universal joints and comprises inner and outer telescoped tubes 1, 2, the inner tube carrying keys 5 biased radially outwards to engage grooves 8 in the outer tube by a stack of Belleville springs 12 acting axially through two frusto-conical wedges 9, 10. The keys 5 may be mounted in a cage 81 which, as shown, is rigid with the tube 1. In a modification, the cage 18 has a lost motion connection with the tube 1 and has a light frictional engagement with the surrounding tube 2, so that when overload occurs with consequent inward movement of the keys 5 to the disengaged position, the cage is turned over the keys, which are then held permanently radially inwards in the disengaged position until a reverse torque is applied to return the cage to its original position. The grooves 8 and the keys 5 are not spaced at equiangular positions around the tubes 2, 1, so that the coupling can only fully re-engage following disengagement on overload at the same relative angular positions between the universal joint forks 3, 4. The grooves 8 extend over substantially the whole length of the outer tube 2, in order that the keys 5 can slide axially therealong when telescopic motion of the two tubes takes place.
