Title: Monitoring passage of sheets
Inventor: HILTON GRAHAM HAROLD
IPC: G01B11/04
Filed: 1984-03-09
Abstract: A method and apparatus for monitoring the passage of sheets (15) along a path comprises causing at least one beam of radiation to intersect and regularly traverse at least a portion of the path of the sheets (15). A detector (7) is provided to sense whether the path of the or each beam is interrupted whereby the passage of a sheet (15) is detected. A computer (not shown) can then be used to calculate the width of each sheet as required. Scanning of the sheets is effected by rotation of optical fibres 2,5 about an axis perpendicular to the plane of the sheets, and presence of a sheet is determined either by the absence of light transmitted across the beam path or by the presence of light reflected by the sheet. <IMAGE>

Title: Insulated-gate field-effect devices
Inventor: COE DR DAVID JAMES
IPC: H01L29/78
Filed: 1984-03-23
Abstract: In an insulated-gate field-effect device a reduction is obtained in the high electric field in the area between the drain (2) and the gate (6) by an appropriate choice of geometry and doping level. The gate perimeter facing the drain (2) bends only through at least one angle ( phi ) of less than 180 DEG , and such a low-doped part (2b) of the drain is present within this bend as to be depleted throughout its depth adjacent the gate (4) by a depletion layer (12) which spreads into the drain (2) away from the bend in the gate perimeter. The perimeter of the drain (2) where it faces the channel area (6) may bend in a complementary shape to that of the gate perimeter. In a particularly simple form both the gate (4) and the channel area (6) may be V-shaped in plan view. <IMAGE>

Title: Slip-controlled brake system for all-wheel driven automotive vehicles
Inventor: FENNEL HELMUT
IPC: B60T8/172
Filed: 1986-09-26
Abstract: In a slip-controlled hydraulic brake system for an all-wheel driven motor vehicle equipped with lockable differentials (2, 3), provided with sensors (S1- S4, 33-36) for measuring the rotational behaviour of the wheels, and electronic circuits (44) for logical combining and processing the sensor signals, and for generating brake pressure control signals by way of which the brake pressure in the individual wheel brakes (16-19) is variable in response to the rotational behaviour of the wheels relative to a reference value, to compensate the increased moments of inertia as a result of the inter axle transmission, via the lockable differentials (2, 3), in this brake system, the brake pressure in the rear-wheel brakes (18, 19) is modulated at a lower control frequency as compared with the brake pressure in the front-wheel brakes (16, 17). The reduction in the control frequency of the rear-wheel brake pressure, is obtained by extending the length of the individual modulating value energisation pulses or the spaces between pulses and may be determined by driving-dynamic criteria, e.g. by the average motor vehicle deceleration or by the motor vehicle speed. <IMAGE>

Title: Process for the regeneration of potentiometric solid electrolyte measuring cells
Inventor: PROFOS PROF DR ING PAUL
IPC: G01N27/406
Filed: 1987-08-07
Abstract: For regenerating a potentiometric solid electrolyte measuring cell (1) which shows phenomena of ageing in operation, manifested as a significant increase in the cell resistance or the cell capacity so that the cell becomes progressively more inert, a current (Ir) is imposed on the cell at least from time to time. The current is preferably direct and is applied until the cell resistance drops to a predetermined value. The current direction is preferably such that the voltage produced across the cell is of greater magnitude but the same polarity as the mean value of the measurement voltage produced by the cell over a period of time. The cell may be taken out of the measurement system during regeneration. Alternatively, the regeneration may occur continuously during measurement using AC or DC or regeneration and measured may alternate at short intervals. <IMAGE>
