Title: Sensing of vapours
IPC: G01N27/404
Filed: 1989-02-07
Abstract: In an electrochemical method of detecting a vapour, for example enflurane or 
isoflurane, the vapour is passed through a membrane into a non-aqueous 
electrolyte solution in contact with an electrode, an electric potential is 
applied to the electrode and electron transfer between the vapour and the 
electrode is catalysed by a mediator substance, whereby a measurable electric 
current is produced indicative of the vapour or its concentration. The 
mediator is preferably a fluoranthene which may be formed into a polymer to 
enable it to be immobilised on the membrane. A novel polymer, poly-11-vinyl 
fluoranthene may be prepared for use in the invention.

Title: Method and apparatus for generating animated images
IPC: G06T13/00
Filed: 1989-09-07
Abstract: A method and apparatus is disclosed for generating 
electronic representations of animated images from stored 
image data elements with reduced computational 
requirements. The image data elements may be made 
available from one or more data base sources (150), and 
may be of any suitable form from which images can be 
computed. A first sequence of relatively low 
resolution frames are computed (210) from the stored 
image data elements, this first sequence of frames 
representing animated images over a given time period. 
A second sequence of relatively high resolution frames 
are computed (220) from the stored image data elements, 
this second sequence of frames representing the animated 
images over the given time period. The number of frames 
in the second sequence is less than the number of frames 
in the first sequence. Corresponding frames of the 
first and second sequence are combined (230) to obtain 
output high resolution frames representative of the 
animated images over the given time period. The 
preferred embodiment of the invention, further includes 
the following steps: spatially interpolating (421) each 
of the frames of the first sequence to increase the 
number of pixels in the spatially interpolated frames, 
and temporally interpolating (421) between frames of the 
second sequence to obtain further frames in the sequence. 
In this embodiment, the combining step (230) includes 
combining the interpolated first sequence frames with 
second sequence frames and further second sequence 
frames.

Title: Polyolefin films having improved barrier properties
IPC: C08J5/18
Filed: 1989-05-02
Abstract: The barrier properties of crystalline polyolefin film can be improved substantially by incorporating a precise amount of a partially incompatible wax into the polyolefin. When the polyolefin is polypropylene or polybutylene, the wax is preferably a paraffin wax. The precise amount of wax, which produces optimum improvement in barrier properties, lies in the range of about 3 to 10 percent based on the weight of the polyolefin. The range in which excellent results are obtained can be broadened by contacting the film with a cooling medium immediately after it is extruded. The film may be annealed to further improve the barrier properties.

communication with the liquid conduit. A piston is 
mounted within each cylinder by a common vertically 
extending piston rod (47) which connects them. The

Title: Printing of fabrics
IPC: D06P5/00
Filed: 1990-09-05
Abstract: By using printing pastes containing a high proportion, e.g. 8 to 15% by weight, of a humectant such as urea or glycerol, fabric printing processes may be developed which can be used both on fabric webs and on garments or garment panels with equal ease. Following the application of the printing paste, and before it has materially dried out, the fabric is confined between a pair of impermeable layers and heated to greater than 100 DEG C. The process is particularly advantageously applied to discharge printing in connection with which it is possible to use discharge printing techniques without the necessity for subsequent washing out and with the production of a visible discharge print immediately after the heat treatment step just noted.

Title: Abrasive sheet and method of manufacturing
IPC: B24D3/06
Filed: 1990-12-24
Abstract: A method of manufacture of a durable abrasive sheet which includes a perforated metal sheet of woven metal mesh or the like having abrasive grit brazedly attached, imbedded in a backing substrate. The method includes the steps of coating a perforated metal substrate with a mixture of an infiltrant and a temporary binder and applying a layer of abrasive grit particles thereto. Thereafter, this product is heated to drive off the binder and attach the grit particles to the perforated metal substrate. The metal substrate having the grit particles attached is then imbedded in a backing substrate such that the portion of the perforated metal substrate having the grit particles attached are at the surface of the backing substrate. In order to provide a cutting type abrasive sheet material the particles are magnetically aligned on the perforated metal substrate and brazed in position. Thereafter, a deformable substrate sheet is place contiguous with the perforated metal substrate. This combination is placed in a press having a deformable pressure plate which is deformable with respect to the grit material used such that when pressure is applied to imbed the metal substrate the grit particles extend into the deformable pressure plate to provide exposed portions of the grit particles in the final abrasive sheet. A metallized ceramic substrate having abrasive grit particles brazedly attached are also utilized for imbedment in a backing substrate. <IMAGE>
