Title: Drive circuit for a stepper motor
Inventor: REES CHARLES EDWARD
IPC: H02P8/12
Filed: 1992-02-12
Abstract: The drive circuit operates in a chopper drive mode (Figs 4a and 5a) during a motor acceleration phase, and in a different drive mode (Figs 4b and 5b) during a subsequent cruise phase. The drive circuit operates the motor in a high torque mode during the motor acceleration phase and in a lower torque, lower power consumption mode, during the subsequent cruise phase. A characteristic, such as inertia, of a load driven by the motor is used to determine the level of the power input to the motor. The motor may be used to drive a coin escrow mechanism of a pay telephone. <IMAGE>
Patent GB-2258068-A (GB)
Title: Dynamically linking modules of software
Inventor: ABRAHAMSSON ANDERS
IPC: G06F9/445
Filed: 1992-06-05
Abstract: The present invention overcomes disadvantages typically associated with linking and loading software modules by delaying linking and performing it dynamically as each function block (task) is executed. A global signal number is send from a block and is stored in a job buffer. This signal number and a receiving block number are then sent from the job buffer and are used to cross reference a global signal distribution table of a receiving block to locate a local signal number. This enables an instruction address to be read from the signal distribution table and the instruction located at that address to be executed. Therefore, whenever a block of software is reloaded and the global distribution table rewritten, the job buffer need not be purged and reloaded, since it stores global signal numbers, i.e. linking is delayed and performed as the receiving block is executed. This software system is used to control a telecommunications switching system in which each exchange corresponds to function block. <IMAGE>

Patent GB-2268403-A (GB)
Title: Pesticidal compositions containing markers
Inventor: LAMBERT DAVID JOHN CHRISTOPHER
IPC: A01N25/00
Filed: 1992-07-02
Abstract: Pesticidal corn positions in liquid form contain one or more marker compounds which fluoresce and/or phosphoresce in the presence of ultraviolet radiation. The preferred marker compound is a bis-substituted stilbene such as bis(triazinyl)stilbene or a bis(benzoxazolyl)stilbene. The uniformity of treatment of a surface with the pesticidal composition may be checked by illuminating a treated surface with ultra-violet radiation and observing the uniformity and intensity of the fluoresence and/or phosphoresence of the surface. The contamination of an operator with the pesticidal composition can be checked by removing any protective clothing from the operator and thereafter illuminating the operator with ultra-violet radiation while the presence and location of any fluoresence and/or phosphoresence is observed.
Patent GB-2258245-A (GB)
Title: Electrochemical desenstization of explosives and propellants
Inventor: CHIN GEORGE
IPC: C25B3/23
Filed: 1992-01-24
Abstract: Potentially hazardous compositions containing solid combustible fuels, oxidants, nitro-containing, nitramine-containing or nitrato-containing compounds and, in many cases, binders are desensitized by electrolysis at low current and over an extended period of time. Compositions containing binders are first oxidized at the anode (17, 18) to cause decomposition and swelling of the binder, followed by further oxidation of the remaining components of the composition or switching of the polarity (46) to cause reduction, as needed. The resulting compositions have a lowered sensitivity to initiation by such external influences as inadvertent impact or inadvertent electrostatic discharge.
Patent GB-2259992-A (GB)
Title: Checking connections
Inventor: WAKAMATSU HIDEKI
IPC: G01R31/04
Filed: 1992-09-25
Abstract: The measuring apparatus of the present invention is capable of distinguishing a loose connection between a DUT 6 and the measuring apparatus 3 from a high impedance in the DUT. The measuring apparatus 3 is also capable of measuring the impedance of the DUT 6 without altering the connections between the DUT 6 and the measuring apparatus. The measuring apparatus 3 applies both DC and AC current signals to the DUT 6 so as to compensate any leakage current occurring within the three-wire cable connecting the DUT 6 and the measuring apparatus. Because of the compensation, when both DC and AC current ammeters (12, 22) indicate substantially zero values, it is assured that a loose connection exists. The measuring apparatus includes a 3-wire co-axial cable for connection to the DUT. In a modification, an AC source 23 is coupled to the coaxial cable via a ferrite core transformer and current ammeters 12, 22 are connected in parallel via isolating elements. <IMAGE>

Title: Automatic steering for non-railed transfer crane
Inventor: KIM YOUNG BAE
IPC: G05D1/02
Filed: 1993-09-15
Abstract: The steering of a non-railed transfer crane is automatically controlled to follow a set lane indicated by road markings. An optical sensor, for example a T.V. camera, monitors the off-centre condition between the cranes real direction of travel and the set lane by comparison of the image with locally generated vertical and horizontal centre lines. The sensor outputs signals indicative of travel deviations (distance as well as angle) between the cranes real direction of travel and the set lane. These signals are applied so as to steer the crane to minimise the said deviations. Steering is by rotating left and right wheels at different speeds. <IMAGE>
