Title: Coloured images
Inventor: SCRUTTON SIMON L
IPC: B44C1/17
Filed: 1989-10-27
Abstract: ABSTRACT OF DISCLOSURE.          .    Multi-coloured images are built-up from thermoplastic, separation negatives obtained for example on a laser printer.  Coloured positive separations are obtained by applying a coloured, transferable non-thermoplastic layer on a carrier over each thermoplastic negative separation, subjecting the assembly to heat and pressure, and peeling apart the assembly whereby coloured non-thermoplastic positive images remain on the carrier sheet.  Each coloured non-thermoplastic positive separation in turn is then transferred to a receptor having a thermoplastic surface.  Each coloured, non-thermoplastic positive is applied over the receptor having a thermoplastic surface, the image being in contact with the thermoplastic surface, the assembly is subjected to heat and pressure and the carrier sheet removed to leave the positive image adhered to the thermoplastic surface of the receptor.  This process is repeated for each colour positive separation to build up the multi-coloured image on the receptor surface.

Title: A bath
Inventor: HOLMES JOHN W
IPC: A47K17/02
Filed: 1990-01-12
Abstract: A bath is proposed for the use of the elderly, disabled or infirm. It includes a sitting member fixedly supported so that a sitting surface thereof is at a convenient height above floor level for a user to sit on and a raisable and lowerable substantially rigid side surround shaped to extend continuously around the periphery of the sitting surface. The surround is movable between a lowered position in which it is located at least substantially below the sitting surface to allow the user to sit on or get off the sitting surface, and a raised position in which it surrounds and projects above the sitting surface to define therewith a bath cavity for receiving liquid. Sealing means are attached to the sitting member and on or attached to the surround for engaging each other to seal the surround to the sitting member in liquid tight manner in the raised position. A closeable and openable outlet is arranged to facilitate the exit of liquid from the bath cavity prior to movement of the surround to the lowered position. This bath makes it possible for disabled people to bathe themselves.

The oval duct end portions are connected to the duct connector frame members and pairs of frame members are po-sitioned in adjacent relation with a gasket member there-between.  Securing means are provided in the connecting members to secure the adjacent frame members to each other and exert a compressive force on the gasket member therebetween.  Portions of the gasket member at the gaps are distorted into abutting and sealing relation with the front edge of the duct in the gap.

Abstract: In the production of foamed plastic articles using a screw extruder, it is known to introduce a gaseous foaming agent into the plastic while the latter is passing through the extruder. It has been found that a foamed thermoplastic with pores or cells of uniform size and distribution can be produced by passing a gaseous foaming agent, e.g. nitrogen gas through a central passage (8) extending substantially the entire length of the extruder screw (1), discharging the agent into the thermoplastic proximate the discharge end of the extruder, and mixing the foaming agent with the plastic immediately prior to discharge of the mixture into a mold.

IPC: F26B13/16
Filed: 1990-06-14
Abstract: Device for Driving a Material Web Abstract A material web 9 to be dried runs across a first drying cylinder 11 ontowhich it is forced by a concurrently running continuous drying wire 10. Thereafter, the web and the drying wire proceed jointly from the first drying cylinder 11 to a suction guide roll 21.  From the latter, at least the drying wire 10 returns to another drying cylinder 12.  This path of the drying wire 10 defines a wire space S. Blown into this wire space, for instance by means of a blow pipe 48,  is drying air at uniform distribution across the machine width and sucked out again by the suction guide roll 21. This suction air is blown at the material web 9 by means of a circulation air fan 49, at the circumference of the suction guide roll 21, and is sucked away again from there by means of an exhaust air fan 44.

Filed: 1991-05-23
Abstract: A multiplexer for the transmission of signals on different carrier frequencies includes a Butler matrix with  a  set  of  delay  elements  secured  to  output terminals of the matrix.   Each of the delay elements differs  from the  other delay elements  in that the delays imparted to signals by each of the elements differ by  an  integral  number of delay units.   The selection of frequency values is made in accordance with the  increment in delay unit so as to develop incremental values of phase shift which compensate for phase shift introduced by the phase shift taper of a Butler matrix.  This permits summation of signals from plural input ports of the matrix without the generation of intermodulation products among the various signal channels.
