Title: Electrically driven vehicles
IPC: B60L11/18
Filed: 1973-06-30
Abstract: 1480053 Control of D.C. motors LUCAS INDUSTRIES Ltd 11 June 1974 [30 June 1973] 31303/73 Heading H2J The motor control system described with reference to Figs. 1 to 4 of Specification 1,480,064 is provided with means responsive to the speed of the vehicle to prevent regenerative braking when the brake pedal is depressed whilst the speed is below a predetermined value and means to maintain regenerative braking, once commenced, after the speed falls below the predetermined value. In Fig. 5 forward or reverse drive is provided by moving a switch 34 to energize a winding 35 or 36 to close contacts 35a or 36a, the latter directly energizing the reverse contactor device R. Contacts 35a control series-parallel circuits consisting of windings 38, 42 controlling contacts 38a, 42a, 42b, auxiliary contacts F2, B2 of the forward and braking contactor devices F, B, contacts 37, 39 respectively closed when the accelerator and brake pedals are depressed and contacts 41 which close when the vehicle speed is above a predetermined low value. Contacts 43 close when the motor current is above a predetermined value. With switch 34 in the forward position, depression of the accelerator pedal operates relay 38, 38a to energize the device F, whose contacts F2 open to isolate winding 42. Release of the accelerator pedal and depression of the brake pedal causes de-energization of members 38 and F, closure of contacts F2 and energization of winding 42, provided the speed is high enough to close contacts 41, contacts 42a then closing to energize device B, which is maintained energized through contacts 42b, 43 if the current is above the predetermined value, even though the speed may subsequently fall to cause contacts 41 to open. Thus the braking is terminated by the current falling below the predetermined value. In the modification shown in Fig. 6, contacts 37, 39, 41 form the inputs to an AND gate 53 controlling a winding 52, whose changeover contact 51 is normally in a position (with contacts 35a closed) to energize the winding 38 and hence device F, even though the accelerator pedal is not depressed. Thus when this occurs there is a rapid response, with the further advantage in that contactor opening and closing is reduced, as the accelerator and brake pedals are depressed and released at speeds below the predetermined value. Contacts 37 are closed when the accelerator pedal is released so that, if the brake pedal is depressed and the speed is above the predetermined value, the gate 53 energizes the winding 52 to change over contact 51 and energize relay 42, 42a and device B, the current-dependent hold-on circuit 42b, 43 functioning as before. Winding 38 may have hold-on contacts connected to contacts 43.

Title: Improvements in or relating to railway signal systems
IPC: B61L23/12
Filed: 1925-11-18
Abstract: 269,815. Automatic Telephone Manufacturing Co., Ltd., Hudd, A. E., and Tattersall, A. E. Nov. 18, 1925. Combined electrical and mechanical systems, non-automatic.-In a railway signalling system employing block working a current of one strength over the block wire operates the block instruments according to its direction while a change in the strength of the current operates a marginal relay in the circuit without changing the condition of the instruments. As described, the marginal relay is used in a system in which a testing current is momentarily supplied to the track at the time a "line clear" signal is given, and again when attempt is made to lower the signal. The section has insulated rails 1, 2 bridged by a track relay 18 at the entrance end at which the signal 5 is situated. The diagram shows the arrangements A, B at the cabins, each having a signalling instrument 6, 22 of usual type. After the usual bell signals, the signalman at A moves his handle 7 to the right to "line clear" position, thus connecting the negative battery 25 through instrument 6, polarized relay 9, wire 23, resistance 12, polarized relay 14, back contact 17 and armature 15 of relay 14, and instrument 22, Inclusion of armature 15 causes the armature to chatter and the current to be intermittent so that instruments 6, 22 and relays 9, 14 are not effectively operated. Handle 7, however, in its extreme position closes contacts 8 connecting a track battery 26 to the rails 1, 2, so that if the section be clear, relay 18 is energized and its armature 19 shunts contact 17, whereupon the circuit traced above is continuously energized, the instruments 6, 22 indicating "line clear," and the armature 15 engages its front contact 16 so that the indications are maintained when armature 19 falls on release of handle 7. Owing to resistance 12, the current flowing is insufficient to operate relay 9. When the signalman at B attempts to pull off the signal 5, contacts 13 are first closed, by plunger, catchhandle, or otherwise. Resistance 12 is thus short-circuited and relay 9 operated, its armature 10 serving again to connect track battery 26 to rails 1, 2 so that if the section be still clear, relay 18 is again energized, its armature 19 closing idly, and a second armature 20 closing the circuit of the lever lock 21, releasing the signal, lever. When the handle 7 is moved to the left to signal "train on line" positive battery 24 is connected up and the reversed current restores the armatures of relays 9, 14 to the position shown. When the handle 7 is restored to the position shown, current flow ceases, and the instruments return to "line blocked" indication. Resistance 12 may be omitted and contacts 13 arranged to shunt relay 14, and a non-polarized relay responding to increased current may replace relay 9.

Filed: 1947-12-01
Abstract: 629,789. Temperature-variable resistances. BAUER, S. G. Dec. 1, 1947, No. 31654. [Class 37] A resistance thermometer for flowing fluids comprises a thin-walled metal tube, extending between inlet and outlet pipes or pipe-couplings, a resistance winding embedded in the outer surface of said tube in heat-conducting, electrically-insulating relation thereto, and a plug within said tube defining with the tube an annular passage co-extensive with the winding and of cross-sectional area substantially smaller than that of the inlet and outlet pipes or couplings. As shown, the tube 8 extends between pipe couplings 9 carrying flanges 10 by means of which the thermometer is inserted into the pipe line 19, 20 and flanges 11 to which is secured the casing 13 protecting the resistance winding 22. The winding is wound in an external thread of the tube 8, the thread having a root conforming in shape to the wire of the winding. The winding may be of bare or varnished wire and the tube of anodized aluminium. The plug is constituted by two metal tubes 15 having their inner ends cupped and secured by a bolt 17 serving also to clamp the pipe couplings and the tube 8 together, and having slots 16 in their walls, through which the flow is diverted into the annular passage between the tube 8 and the tubes 15, the slots also increasing the turbulence of the fluid in flow. The couplings 9 are shaped as shown, so that the internal diameter of the tube 8 exceeds the effective diameter of the pipe couplings, the increased area of heat contact between the fluid and the tube 8 and the increased velocity and turbulence of the fluid in the annular passage increasing the quickness of response of the thermometer to changes in temperature.
