This mixture is then contacted at 45 a hydrocracking catalyst and hydrogen under hydrocracking conditions at a reduced temperature below 425 DEG C, resulting in a product 50 having a normally liquid portion which may be used directly as a low- sulfur, low-nitrogen fuel oil. <IMAGE>
Patent GB-2084766-A (GB)
Title: Voltage regulator
IPC: H02J7/14
Filed: 1981-09-21
Abstract: A voltage regulator for controlling charging of a battery 4 by an alternator 1 has a zener diode bank 8,9 which conducts when charging voltage exceeds a maximum limit, and a resistor 12 for monitoring voltage when zener current flows through it. A differential amplifier 15, 17 drives the field winding 22 of the alternator according to the voltage drop over the resistor and has current limiting on its drive output. By shorting out one set of zener diodes 9 the output of the alternator is reduced, permitting thereby charging of 12 or 24 volt batteries, for example.

Title: A method of detection and separation of wheel drag and braking forces suitable for incorporation into braking control systems
Inventor: ALLCOCK DEREK
IPC: B60T8/171
Filed: 1982-04-23
Abstract: This invention relates to an arrangement for monitoring selected forces acting on the members supporting the road wheel assemblies of a vehicle. The arrangements consist of strain or force transducers strategically placed to measure these forces. The output signals from the transducers could be suitably processed and used in an anti-lock braking system to;     (i) ascertain when any wheel is about to lock, (ii) provide a measure of the tyre/road adhesion conditions in terms of reacted brake torque at the instant the wheel is about to lock.   The output signals when suitably processed could further be used to provide a measure of the forces acting at transverse wheel positions to detect in equality in these forces due typically to tyre deflation. When used in conjunction with the output signal from a strain or force transducer on the brake pedal mechanism, the output signals from the wheel positions could be processed to provide a measure of the brake efficiency. <IMAGE>

Abstract: A circuit arrangement for performing a gamma correction or an inverse gamma correction on digital input signal Vi applied to an input terminal (1) comprises a first read only memory (12) which stores the function P = loga ({logAVi) where A and B are arbitrary constants, a second read only memory (6) which stores the function Q = logBG where G is the correction factor, an adder (4) which adds the outputs of the read only memories (6,12) and a further read only memory (13) which stores the function A exp Ä{B exp ({R)Ü where R= P+Q. This enables the usual multipliers to be replaced by an adder which is easier to produce in digital form. In a modification for performing the inverse gamma correction operation the adder (4) is replaced by a subtractor. When operating on analogue signals, the log, log(log) and double exponential functions are performed by non linear amplifiers. <IMAGE>

Title: Improvements in or relating to data interconnecting networks
Inventor: AMPULSKI JOSEPH WILLIAM
IPC: H04J3/06
Filed: 1983-09-07
Abstract: A circuit for signal generation and synchronisation is disclosed for a ring network in which a number of stations communicate with each other. The circuit, which is provided at each station in the ring, includes a phase locked loop which loosely couples the transmit and receive clocks of each station during a repeater mode of operation. During a transmit mode the receive and transmit clocks are de-coupled so that phase delay around the ring does not degrade the transmission clock each time a transmission is initiated. The circuit includes logic gates for detecting the transmission of a token, means for generating a token and means for jam syncing the transmit and receive clocks to detect transitions in the incoming data during the repeater mode and after a token has been generated at the end of the transmit mode.

Title: Toilet seat lifting device
Inventor: SEABROOKE ALLAN B
IPC: A47K13/10
Filed: 1983-09-13
Abstract: An operator-controlled, toilet- seat lifting device applies a permanent bias force, for example, by means of a helical spring 42, to the seat in a direction tending to raise the seat. The weight of the seat is sufficient to overcome the permanent bias force so that the seat normally assumes a horizontal or down position. To raise the seat 14 the user increases the bias force, for example, by depressing a pedal 60 actuating a cable 64 to wind up the spring 42 so as to overcome the weight of the seat and cause the seat to swing upwardly. As the seat is held in raised position solely by bias force, forcible manual lowering of the seat when in its raised position does not damage any of the components. <IMAGE>
