Title: Anti-skid brake control apparatus
Inventor: TAKAYAMA TOSHIO
IPC: B60T8/66
Filed: 1989-11-17
Abstract: The control apparatus takes wheel speed signals r omega  and feeds them to a vehicle reference speed generator (11) and a wheel acceleration calculator (12) and calculates at least one of a slip speed and a wheel acceleration to feed to a judging device (13). The acceleration is a time derivative of the rotational speed of a wheel. The threshold value setting device (15) temporarily determines a threshold value for at least one of the slip speed and the wheel acceleration, which threshold value is also fed to the judging device (13). To prevent the control apparatus overreacting to large fluctuations in wheel speed or acceleration due to uneven road surfaces, the threshold value is increased with a delay when the slip speed or wheel acceleration exceed it. The increase to the threshold value may be suppressed if the slip speed exceeds the threshold for longer than a predetermined time interval. …<IMAGE>…

Title: Switching circuits
Inventor: FAYFIELD ROBERT W
IPC: H03K17/66
Filed: 1990-02-08
Abstract: In a DC circuit, a current sink signal or a current source signal is selectively supplied to a load 31 in dependence upon a drive signal applied at an input terminal 11 and the polarity of a supply voltage applied at terminals 30, 32. Transistor 19 is turned on by an ON pulse. If terminal 30 is positive with respect to 32, diode 38 is reverse biassed to inhibit transistor 23 while transistor 20 is enabled. The conduction states of 20, 23 are interchanged when supply polarity is changed. A bridge rectifier 26-29 enables Vcc to be always positive. In alternative arrangements transistors 20, 23 are selected by a control of conduction of an associated drive transistor or by bringing the potential of one of the bases to same potential as its emitter. The load 31 may be a relay or an input to a programmable logic controller. …<IMAGE>…

Title: Drilling fluid composition
Inventor: BRANKLING DAVID
IPC: C09K8/26
Filed: 1991-02-23
Abstract: Drilling fluids are used to remove rock cuttings generated during the boring process in the drilling of wells. The drilling fluid has the composition of a water-soluble organic fluid maintained as the continuous phase of an emulsion by the action of a salt-containing aqueous solution material emulsified into the water-soluble organic fluid by suitable surfactants. The water-soluble organic fluid is insoluble in the emulsion with the salt-containing aqueous material. The water-soluble organic fluid is soluble in sea water or fresh water and upon disposal of the drilling fluid or coated drilled cuttings the emulsion organic fluid phase is resolubilised and removed from the immediate environment.

IPC: H04L12/44
Filed: 1991-04-19
Abstract: A broadcast tree network comprises a master hub 22, and a series of other hubs 12 interconnected by bidirectional data links 16.

Title: Three dimensional structure forming apparatus
Inventor: YAMAMOTO MASANOBU
IPC: B29C67/00
Filed: 1991-07-25
Abstract: Apparatus is provided for forming a three-dimensional structure by sequentially laminating hard resin layers by repeatedly irradiating the surface of a liquid photosetting resin (A) with a light beam in a pattern corresponding to the pattern of one of a plurality of parallel decomposed planes obtained by slicing an optional stereographic image and then spreading another layer of resin over the hard resin layer. To obtain an accurate pattern the beam diameter needs to be constant requiring a uniform layer thickness and accurate level control. To achieve this the main tank (2) of the apparatus includes a lead control system comprising a supply tank (8), means to supply resin from the supply tank to the main tank at a rate such that it overflows a wall portion (9) of tank and means to return the overflow to the supply tank. The overflow may be drawn off by suction. The level may be further adjusted by lowering into the tank, a bar controlled by a laser level sensor. <IMAGE>

Patent GB-2260243-A (GB)
Title: Signal monitoring apparatus
Inventor: BOULTON DAVID
IPC: G01R29/027
Filed: 1991-10-03
Abstract: Signal monitoring apparatus includes means for detecting signal transitions and for providing an output signal indicative of elapsed time between adjacent pairs of detected transitions. Control means address selectively a plurality of latches each associated with one of a plurality of successive ranges of elapsed time values. Each latch means is coupled to indicator means (20), for example, a coloured light. Consequently, the provision of an output signal from the signal transition detector indicative of a particular elapsed time value causes the latching of the latch means associated with the appropriate time value range and, hence, activates the corresponding indicator (20). The monitoring apparatus is, accordingly, capable of providing a very simple and clearly readable display.

Abstract: The open, outer end of spirally-coiled tubing 1 carried between flanges 3 of a rotating spool 2, moves first down and then up through the interface between air 9 and water 8 to admit quantities of air and water in turn to the tubing 1. Continued rotation translates the successively-admitted quantities of air and water radially inwards within the tubing 1 for discharge under pressure from the inner end 5 of the tubing into a chamber 6. As a modification, the initial length of the coil at the open end (44, Fig. 6) may be of enlarged diameter and have an air-bleed hole (47) to facilitate entry of water. More than one coil may be used, the coils being carried side-by-side with their open ends (24, Fig. 3) distributed angularly from one another around the rotor (20). Rotation of the rotor may be powered by wave or tide movement, or by wind and/or water-flow, and the pumped air and water may be used to drive a turbine for electricity generation (Figures 4 and 5). <IMAGE>

It is has been found that variation of the fraction of silicon and/or germanium enables precise values of optical attenuation and/or phase shift to be obtained. Preferably, a transparent substrate is coated by chemical vapour deposition with Si and/or Ge, a layer of photoresist is applied which is then imagewise exposed and developed so that the exposed areas of the Si/Ge layer can be etched and the remaining photoresist removed to leave the desired phase shift photomask. Preferably the photomask is an attenuated or half tone phase shift mask.
