Patent GB-2032043-A (GB)
Title: A method of lining a pipe
IPC: B29C63/34
Filed: 1979-09-07
Abstract: In a method of lining a pipe 10 an adhesive layer is formed on the inner surface of the pipe which layer can be activated at a first temperature value, an adaptor 11 including a tubular member having an internal diameter at least equal to that of the pipe and a recess 16 in one end in which the pipe can be engaged is provided and a tube 25 of thermoplastic material is inserted into the pipe to overlie the adhesive layer and extends out beyond the end of the pipe. The tube 25 is passed into the tubular member and the end of the pipe is engaged in the recess. Thereafter radial force is applied to the thermoplastic film and the assembly is heated by relative axial displacement between the pipe and a source of heat, whereby the source of heat moves relatively towards the adaptor so as to raise the temperature to a value below the said first value, to render the thermoplastic film to a plastic state, and the entrapped gases are allowed to vent between the pipe and the recess. Finally the assembly is heated at least to the first temperature value to activate the adhesive. Alternatively the adhesive layer may be applied to the tube. <IMAGE>

Title: Decompression Bubble Detector
IPC: G01N29/032
Filed: 1979-10-04
Abstract: A decompression bubble detector comprises a pulsed ultra-sound transmitter/receiver which is scanned across a cross-section of tissue and the total number of pulse echoes received in a preselected time interval (e.g. 1.5 sec.) is counted. Changes in the total number of pulse echoes counted in successive time intervals are used to monitor the decompression. A single transducer 1 is scanned by means of a driven eccentric cam 4 and a cam follower 6. A sin/cos potentiometer 3 generates a signal related to the angular position of the transducer 1 connected to a delay 20 so that pulse counting can be arranged to coincide with the passage of the transducer 1 across the target. A fixed number is subtracted at 25 from each count, and the difference is recorded by pen recorder 28. <IMAGE>

Title: Wet Oxidation Treatment
IPC: C02F11/08
Filed: 1979-11-13
Abstract: The wet oxidation process e.g. for the purification of waste waters, is carried out with an oxidizing agent containing at least 60% oxygen. The employment of liquid oxygen eliminates the need to install expensive compression units. The addition of ozone improves the reactivity of the oxidation reaction. The addition of organic substances to the waste waters can give autogenous heating.

Title: Carbo-metallic oil conversion with controlled CO:CO2 ratio in regeneration
IPC: B01J29/90
Filed: 1980-11-12
Abstract: In a process for the production of high octane gasoline and/or other valuable lower molecular weight products from carbo-metallic oils (such as crude oil, topped crude, reduced crude, residua, the extract from solvent de-asphalting and other heavy hydrocarbon fractions) by cracking in a fluid catalytic cracking riser zone operated with a vapour riser residence time of 0.5- 10 secs at 900-1400 DEG F and 10-50 psia, a conversion of at least 50% per pass and a coke production of 4-14% based on the weight of the feed and 0.3 to 3% based on the weight of the catalyst, the catalyst is regenerated to a carbon content of at least 0.25 ml% with at least the major proportion of the coke being burned at a CO:CO2 molar ratio of at least 0.25. This incomplete combustion helps to avoid supplying the regenerated catalyst with more heat than is desirable for cracking the feed.

Title: Boards with prepared surface for painting
IPC: B44F1/04
Filed: 1980-11-13
Abstract: An artists board (1) for a picture or design representing a stained glass window comprises a stiff base sheet (2) to which a metallic finish sheet is applied. The metallic surface may be treated with a clear varnish, lacquer or plastic to maintain its lustre. The surface is then printed with guide-lines to represent a design 5 dividing it into discrete portions 6 for chosen colouring by spirit or water based coloured inks. The printed lines may be thick black lines to represent the lead strips of stained glass work, or thin, broken for the user to cover with suitable thick dense black lines. Translucent ink applied permits the lustre of the metallic surface to shine through, and where the metallic surface is left bare it can represent clear glass if the surface is silvery such as by using an aluminium foil. The board may be part of a kit including a range of boards bearing different designs and pens or brushes for applying the translucent inks. <IMAGE>
