Title: Improvements in safety devices for colliery or other vehicles subjected to traction on inclines
IPC: B61H9/04
Filed: 1923-06-01
Abstract: 212,466. Williams, O., and Morgan, D. T. June 1, 1923. Back-struts; actuated by relaxation of pull.-Colliery or other vehicles are arrested on inclines in the event of relaxation of the pull on the haulage rope due to breakage or other cause, by back-struts that are lowered into engagement with the track upon longitudinal movement of the draw-bar. Back-struts 3 pivoted upon the wheel axles have short arms 1 in engagement with abutments 12 on the draw-bar 2, to which is permitted longitudinal sliding movement limited by abutments 10, 11 arranged to contact with the transverse beams 9. The back-struts 3 are thus held in the raised position as long as there is a pull on the draw-bar, but fall by gravity when this pull is relaxed and engage the ground or the sleepers 8. The fall of the struts 3 may be limited by the engagement of the abutments 12 with the beams 9, the resilience of the hooklike arms 1 giving a cushioning action, or such fall may be limited by members 15 secured to the struts 3 and embracing the draw-bar 2 with which they are adapted to engage. One end of a pivoted bar 18 may be interposed between the forward beam 9 and bracket 11 on the draw-bar to render the device inoperative when desired. According to the Provisional Specification the fall of the struts may be assisted by springs and there may be a positive connection as by lever mechanism between the draw-bar and the struts.

Title: Improvements in and relating to the feeding of steam generators
IPC: F22D1/28
Filed: 1933-05-22
Abstract: 420,079. Feedwater supply apparatus for steam boilers. TRIGGS, W. W., 57, Lincoln's Inn Fields, London.-(Gerschweiler Elektrische Zentrale Ges.; Giengen-on-Brenz, Germany) May 22, 1933, No. 14730. [Class 123 (ii)] The feed pump 5 for the return feed apparatus 4 operates at above atmospheric pressure but below boiler pressure and after the feed apparatus has been emptied of water the steam therein is utilized in the indirect contact feed heater 3. The valves 10, 12, 14 are opened, against springs, in the correct sequence, by oil pressure derived from a system comprising pumps 18, 19 and valves 21, 22 operated by floats 23. In a modification the feed system is in duplicate, and a single feed heater is arranged between the two feed apparatus and the boiler. One float control only is used with each oil system, and valves responsive to the steam pressures in the two feed cylinders ensure alternate operation of the two feed systems. In a second modification, in addition to the feed heater 3, there are two feed heaters arranged in series between the cylinder 4 and the boiler. Each heater is provided with a valve controlled exhaust steam coil and the valves are operated in sequence as the pressure in the cylinder 4 falls to predetermined values. A pump is arranged between the cylinder 4 and the series heating arrangement to overcome hydraulic friction. In this second modification an auxiliary feed cylinder and circulating pump may be arranged between the cylinder 4 and feed heater 3. This auxiliary cylinder is connected at the top to the feedcylinder and exhausts to the feed heater. In a further modification, employing a superheater, the exhaust from the feed cylinder passes through a coil in the boiler or operates a steam engine before reaching the coil in the feed heater. The feed and circulating pumps may be driven by steam exhausted from the feed apparatus, a steam accumulator being arranged between the feed apparatus and the pumps. In a further modification part of the exhaust steam may be utilized in a low pressure network.

Title: Improvements in control systems for electric motors
IPC: B60L9/28
Filed: 1952-06-17
Abstract: 735,938. Changing number of phases. SCHWARZ, B. June 16, 1953 [June 17, 1952], No. 15243/52. Class 38 (2). [Also in Group XXXVII] A self-propelling or driven frequency converter is_provided with commutator C and sliprings SL connected to its rotor windings and is fed from a transformer the primary winding P of which is connected to a single phase supply SP. As shown, the transformer has three legs with the primary winding consisting of two series-connected coils on its outer legs, whilst the secondary winding S is arranged on the three legs and has open three-phase connection with the stator winding St of the frequency converter as well as the primary winding PR on the rotor of an induction regulator IR. The secondary winding SR of the induction regulator is connected, in series with the transformer winding S, to commutator brushes B of the frequency converter, the slip-rings of which are connected to polyphase induction motors IM1, IM2, IM3. The induction regulator may be replaced by other suitable types of variable voltage transformers. An auxiliary motor AM may be used for starting the frequency converter. In a modification, Fig. 2 (not shown), the transformer and induction regulator IR each have additional secondary windings for obtaining simultaneous regulation of the stator and rotor voltages of the frequency converter, so that the voltage/frequency ratio on the output side of the machine is made variable. When the frequency converter is at rest, there is no flux in the centre leg of the transformer. When the frequency converter rotates, however, voltages derived from the stator windings St and commutator C are applied to the secondary windings of the transformer and, in consequence, a flux is set up in the centre leg and the transformer carries three-phase flux. Once rotation of the frequency converter is initiated, it will be continued by the rotating field that has been set up. At first the frequency converter is driven at a speed sufficient to enable it to function as a phase converter, and is afterwards connected to the supply. The induction regulator is then adjusted so that the machine rotates at substantially synchronous speed resulting in low frequency and voltage at its slip rings. The induction motors are connected to the slip rings and the induction regulator adjusted to reduce the speed of the machine for starting and accelerating the induction motors. Reversal of the induction motors may be effected by driving the frequency converter above its synchronous speed. Specification 684,415 is referred to.

Title: Improvements in or relating to power-driven governor-controlled variable gear-ratio-transmissions
IPC: F16H59/44

Abstract: 786,665. Change-speed gear control. SMITH & SONS (ENGLAND), Ltd., S. May 26, 1955 [June 16, 1954], No. 15286/55. Class 80 (2). Change-speed gearing is automatically controlled by an eddy-current governor comprising relatively-rotatable magnetic and armature members, one of which is driven from the output shaft so as to induce rotation of the other member against spring action through an angle dependent on the output speed and thereby effect speed changes, while the loading of the spring or the magnetization of the magnetic member is varied according to the engine suction or throttle position. As shown, the armature member 63 is rotated by the speedometer drive 61 within a member 64 which houses an electromagnetic coil 65 and whose induced rotation is restrained by a spring 67, the hub of the member 64 having cam surfaces 71 controlling switches 69 which are thus operated successively to energize solenoids effecting gear changes. The coil 65 is energized through a variable resistance controlled by the engine suction or throttle position. In another form, a permanent magnet is rotated from the output shaft within an armature member carrying switch-operating cams and restrained by a spiral spring, one end of which is connected to the armature member while the other end is connected to a plate which is rotationally adjustable through a Bowden cable by the engine suction or throttle position.
