Patent GB-2081920-A (GB)
Title: Photographic colour reversal process
IPC: G03C5/50
Filed: 1981-08-12
Abstract: A photographic colour reversal process of reproduction is provided in which, after black and white development of the imagewise exposed photographic element, some or all of the unused developing agent is left in the element and in which the photographic element contains additional silver halide over and above that required to produce Dmax in the colour image such that on development in the reversal stage using a colour-forming developing agent the additional silver halide is sufficient to ensure that the residual black and white developing agent is oxidised. The colour image may be a retained image or a transfer image. The amount of residual black and white developing agent can be reduced by draining the developed element. When the colour image is a transferred image, the amount of residual black and white developing agent is reduced on lamination of the photographic element to an image-receiving material or cover sheet. The process can be carried out using only one processing solution, i.e. the black and white developer. The colour- forming developing agent can be introduced by unblocking and/or from the image-receiving material or cover sheet. The black and white developing agent may be incorporated in the photographic element.

Title: More-vibration-free concrete breakers and percussion drills
Inventor: WALTON JEAN
IPC: B25D9/10
Filed: 1982-10-27
Abstract: In order to reduce vibration on concrete breakers and percussion drills, a system for internal absorption of recoil is devised. Accordingly Fig 1 is a diagrammatic representation of a basic device to be incorporated in the "drill" design. MP2 is a mass which absorbs the recoil and can then return to add impact to the tool on the next stroke. C3 is the main "tuning" compliance. The "explosion" chamber is the volume around C4. It is shown how this system can produce a breaker that can approach zero recoil vibration and simultaneously be lighter in weight. <IMAGE>

Title: Processes and apparatuses for recovering clean water and solids from aqueous solids
Inventor: GREENFIELD CHARLES
IPC: B01D12/00
Filed: 1983-04-20
Abstract: Aqueous solids containing a heavy, relatively non-volatile oil are mixed in tank 164 with a relatively low viscosity, relatively volatile, water- immiscible light fluidizing oil fed through 164 to obtain a mixture. The mixture is subjected to a dehydration step by heat evaporation using evaporators 178, 190, 198 whereby substantially all of the water and at least a part of the light oil are evaporated and travel through 188, 252, 180 and get condensed. The condensates travel through 192, 184, 182 and get separated in separator 186 into clean water and light oil respectively. The light oil is then largely separated from the solids along with heavy oil in the centrifuge 12. Those solids carrying residual light fluidizing oil are then repulped with water in tank 242. The resulting mixture is fed via line 250 to one of the evaporators 190 where it is heated. The steam, thus produced, removes the light oil from the solids. <IMAGE>

Title: Improved method and composition for coating a surface of an intermediate rubber product to reduce or eliminate tackiness and a coated intermediate rubber product thereby obtained
Inventor: ROBERTS FRANK SOMERVILLE
IPC: B29C37/00
Filed: 1983-09-13
Abstract: A method of coating tacky surfaces of natural and synthetic rubbers or other elastomers during the course of manufacture but, prior to vulcanisation, to reduce or eliminate tackiness involves coating the elastomer with a dilute aqueous suspension of a clay of the montmorillonite type in the presence of an alkali metal salt of a weak acid in addition to the usual wetting agent which is incorporated in the suspension to reduce surface tension. The salt inhibits the normal bonding of the wetting agent to the montmorillonite clay thereby increasing the effectiveness of the wetting agent in reducing surface tension such that a lower quantity of wetting agent is required.
