Patent GB-2157785-A (GB)
Title: Pipe connector
Inventor: JARDINE ROBERT WILLIAM
IPC: F16L21/04
Filed: 1985-04-19
Abstract: A pipe connector forming a coupling for joining adjacent free ends of two axially aligned pipes, comprises a sleeve (10) into which the end regions of the pipes (15) are inserted, a pair of co-axial elastomeric sealing rings (13), a pair of co-axial locking rings (14) and a pair of co-axial clamping rings (16). Rings (13, 14, 16) are slid onto the pipe ends and have complementary axially tapered surfaces such that by tightening tie bolts (17) between clamping rings (16) locking rings (14) are deformed radially inwardly and, by wedge action cause sealing rings (13) to seal against the pipe surface. Further deformation of locking rings (14) as bolts (17) are tightened, causes the inner surfaces of locking rings (14) to grip the pipes to prevent axial movement thereof. <IMAGE>

Title: Control systems
Inventor: BROWN ALLAN RICHARD WILLIAM
IPC: G05D23/19
Filed: 1985-04-23
Abstract: A central heating control system includes a control panel 6 housing a timer 12. The timer 12 has three programme sequences for controlling three groups of radiators (TU1 to TU9) each group being independently controlled. The control panel (6) also includes switch units (32 to 66) which are selectively operable to isolate each radiator (TU1 to TU9). The switch units (32 to 66) are triggered by infrared signals transmitted by a portable control unit 8. The signals may be received directly by the panel 6 or indirectly through spaced windows 80 to 84 coupled to the control panel by an optical fibre network. The system provides an exceptionally convenient method of modifying a programmed heating system. <IMAGE>

Title: Method for extrusion processing of cellulose-bearing materials
Inventor: HUBER GORDON RAY
IPC: B29C48/395
Filed: 1986-01-22
Abstract: A defiberated product is produced by extruding coarse wood or wood derived materials having a moisture content of 5 to 75 percent by weight, by conveying it by a screw (32) through a barrel 27 in which the material is subjected to increasing shear and compression forces, at a temperature of 212 DEG F to 650 DEG F and pressure of 200 to 5,000 p.s.c., and is extruded through a restricted die orifice (106). The pressure of the material in the barrel is sensed by a sensor (84) which controls the supply of hydraulic fluid to die chambers (112,114), so that successive sensed high or low pressure respectively causes a die piston head (78) to be displaced conically, to increase or decrease the size of orifice (106) and produce a corresponding reduction or increase in the barrel pressure. <IMAGE>

Patent GB-2174261-A (GB)
Title: Data monitor
Inventor: JOHANSON FREDERICK R
IPC: G06F3/02
Filed: 1986-02-27
Abstract: A data monitor (10) (e.g. for an underground mining machine) receives signals from several transducers (12) on the machine to monitor operating functions of the machine. Values determined by the transducers are displayed (34) for the operator and stored in both short term and long term memories for recall by maintenance personnel. A microprocessor (20) is arranged to cause the display device to display either any out-of-bounds value monitored for each channel function consecutively or every function value monitored for a particular selected channel. In addition, maintenance instructions are periodically displayed for necessary personnel to ensure that the maintenance is performed. The monitor may be programmed either at the machine or through a portable data transfer unit (48) which is programmed at a remote location and carried to the machine for access by the monitor to change its instruction memory data. Stored data in the short term and long term memory may be transferred to the portable data transfer unit (48) and the portable unit hand carried to a remote location for analysis of the stored data. <IMAGE>

Title: High solids processing of kaolinitic clays with post-leaching oxidation
Inventor: THOMPSON III THOMAS DICK
IPC: D21H17/68
Filed: 1986-03-14
Abstract: A process for beneficiating a poor grade crude kaolinitic clay mineral to produce a clay filler for use in papermaking to improve the brightness of the paper product. The crude kaolin clay is blunged with water containing a dispersing agent to form a high solids fluid aqueous clay suspension. This clay suspension is then screened and fractionated to reduce the particle size thereof to 92-95% finer than 2 microns. The fractionated clay suspension is treated with an alkaline leaching solution containing a reducing agent (e.g. dithionite) effective in converting ferric ions to ferrous ions and, preferably, a water-soluble anionic phosphate. The leached clay suspension, which has a solids content of at least 55%, is then treated with an oxidizing agent (e.g. Na perborate, hydroxylamine hydrochloride, diethylhydroxylamine) to oxidize unreacted leaching agent and byproducts formed during the leaching process.

Title: Event recorder
Inventor: HOLDER ANDREW STEPHEN
IPC: G06F19/00
Filed: 1988-10-17
Abstract: A data recorder capable of capturing transient events, of particular use in detecting the changing situation just before the onset of Apnoea and Oxygen deficiency in infants. Both analogue and digital data are input to a microprocessor chip 1 and analysed. Also data from a real time clock 5 are input to the microprocessor in order that the date and time of any event recorded can be established. The data are stored sequentially in random access memory (RAM) in the form of a removeable "credit card" sized cartridge 7. When the cartridge is full the new data overwrite the oldest data ensuring that the most recent period is retained. When an event happens on any attached equipment the recorder is triggered into shutting down, e.g. after a preset interval. The RAM cartridge can then be removed and by inputting the data to a computer the period surrounding the event can be studied. <IMAGE>
