Title: Controlling remote electrical appliances via the mains supply
Inventor: EDWARDS PHILLIP JULIAN
IPC: H04L12/28
Filed: 1989-03-06
Abstract: Remote electrical appliances (e.g. lamp 1, heater 4) are controlled via the mains using a controller terminal 10 for transmitting and receiving mains-borne data packets and a plurality of remote terminals 6 to 9 for controlling the appliances in response. Each terminal has a processor having a clock and the clocks may drift relative to each other. Then when data packets are sampled the bits may not be sampled in the optimum position i.e. the centre of the bit interval. To overcome this, each terminal samples (Fig. 8) at one rate to detect the presence or otherwise of a data packet, and samples at a faster rate, when a synchronisation waveform has been detected, to determine accurately the timing of a particular characteristic such as a rising edge in the synchronisation waveform, to enable the terminals to be synchronised and sampling at the optimum time without very rapid sampling. <IMAGE>

Title: Manufacture of extruded products
Inventor: HOWELL BARRY GEORGE
IPC: C08J5/00
Filed: 1990-06-14
Abstract: Polymeric material is plastified in an extruder and is then divided into a major part and a minor part. Either the major part or (more often) the minor part is modified by a chemical reaction, such as grafting (any necessary ingredients being added, if not already present). The major and minor parts are then recombined in an extrusion head so that the modified and unmodified materials form distinct parts of the product. In this way, a single extruder can be used to make, for instance, a product with surface characteristics modified by grafting, wire-covering with only a surface layer crosslinked, or heat-sealable crosslinked packaging film.

Title: Method of forming an impervious barrier beneath a thoroughfare
Inventor: TOWN PETER JOHN
IPC: E02D19/16
Filed: 1991-08-17
Abstract: A method of forming an impervious barrier within or below material supporting a thoroughfare comprises applying a liquid composition to the porous material beneath the thoroughfare. The composition penetrates as a liquid and then its components react to form a substantially impervious barrier within or below the layer of porous material. Typically the composition comprises a chemical grout, miscible with water, whose components react by polymerisation into an impervious gel. The composition may be applied by simply flooding it directly onto the porous material or by controlled injection through pipes driven into the porous material at pre-determined intervals and to the required depth to provide diffusion. Primarily for use on railway tracks crossing bridges, viaducts or other supporting structures, it may be applied to structures such as aqueducts and road bridges where necessary to control water permeation from above.
