Title: Electrical vehicle control apparatus
Inventor: DILGER LAWRENCE
IPC: B60L50/30
Filed: 1983-11-14
Abstract: Apparatus for controlling the traction motor 12 of a vehicle 10 is provided in the form of a motor- generator 30 which is controlled by control means 34 to supply variable power to a given length of track and which is connected to an energy storage source including a flywheel 28. The apparatus is fixedly located relative to the given length of track and when a vehicle 10 on that length of track is decelerated, energy from the vehicle 10 is transferred through the traction motor 12 to the motor/generator 30 and the flywheel 28. A transportation system comprises a number of successively arranged lengths of track each with its own dedicated control apparatus and it is preferred that where there are N vehicles there should be at least (N + 1) lengths of track to ensure that there should be only one vehicle per length of track and at least one length of track should be vacant to enable the flywheel to be driven up to speed from the power source driving the motor/generator. The control means of each apparatus may respond to a number of predetermined parameters to ensure that security of the system and to control the vehicle in accordance with a predetermined speed/distance/time profile. <IMAGE>

Patent GB-869338-A (GB)
Abstract: 869,338. Delivering measured quantities of liquid. HOBLEY, A. B. Dec. 16, 1959 [Dec. 23, 1958], No. 41499/58. Class 106(5) In order to measure the fuel consumption of an internal combustion engine a float 10 provided in a fuel container 1 carries an outlet control tube 6 adapted to define the lowest level from which fuel can be drawn from the container and, together with the float, to be temporarily secured at each of two float levels for indicating the volume of fuel drawn off between such levels. The tube 6 is slidable through a boss or gland 7 mounted on a filler cap 2 and surrounds with clearance a draw-off pipe 3 connected for example through a valve with the fuel pump of the engine. In operation, with the initial fuel level at 11, the tube 6 is allowed freedom until the float is steady when the tube 6 is secured by a screw 8. Fuel can then be drawn from the container by the fuel pump to the level 12 defined by the lower end of the outlet tube 6, after which this level can be used as a starting level, the tube 6 released and secured at its new level as set by the float, and further fuel can then be drawn from the container to the level 13 defined by the lower end of the tube 6. In a modification, the pipe 3 is dispensed with and a flexible tube is connected directly between the lower end of the tube 6 and the lower outlet of the container, a draw-off hole then being provided in the tube 6 below the float 10.
