Title: Control of motor for tactile indicator at pedestrian road crossing
Inventor: DULEY RICHARD KEITH
IPC: H02P7/288
Filed: 1989-08-10
Abstract: A control system for a D.C. electric motor (11) provided to drive a rotary tactile indicator for use by blind persons, comprises an amplifier circuit (OA3, OA4, TR1) to limit and maintain the current supplied to the motor to a chosen maximum value so as to define and maintain a maximum torque which the motor can supply. A further amplifier (OA1) stabilises the supply voltage to the motor in the "off load" condition. The system controls the speed of the motor (1) to a chosen value under varying applied torque conditions. An interlock circuit (TR2, TR3, INT) couples operation of the motor (11) to other devices at a pedestrian crossing. <IMAGE>

Title: Method and apparatus for per process mounting of file systems in a hierarchial file system environment
Inventor: LYON TOM
IPC: G06F17/30
Filed: 1989-11-01
Abstract: In a computer system having a hierarchical file structure a file system is provided wherein per-process mounting of file systems can be performed. To provide per-process mounting, a temporary directory tmp is created off the current root directory. The file system, starting at the root directory, is then mounted on the temporary directory using an innovative loop-back file system function which results in the file system being duplicated but having the temporary directory as its root directory. A mount can then be performed on the temporary directory without affecting the original file system. A change root directory command is then executed to change the root directory to the temporary directory whereby execution continues on the file system having the temporary directory as its root. <IMAGE>

Title: Measuring batch thickness in glass melting furnace
Inventor: CHARLESWORTH DONALD
IPC: G01F23/26
Filed: 1990-05-19
Abstract: The thickness of a layer of insulative batch on conductive molten glass in an electric glass melting furnace with power supply electrodes 16 is measured by ascertaining the extent of attenuation of the voltage gradient within the melt resulting from the presence of the layer of batch. The measurement is effected by taking a voltage reading V2 using two sensor electrodes 15. This reading V2 is linearly related to the position of the underside of the batch layer. Since the batch-plus- melt level is constant, a measure of batch thickness is thereby obtained. The measurement may be used to control the furnace power supply to maintain a constant batch thickness. <IMAGE>
