Title: Improvements in bioelectrocatalysis
Inventor: EDDOWES MARK JAMES
IPC: C12P1/00
Filed: 1981-12-09
Abstract: Bioelectrocatalysis is the use of materials derived from biological systems as catalysts for reactions occurring at electrodes. These materials are called electroactive biological materials. The applicants have found that the electroactive biological material can be bound to the electrode by providing within the electrically conductive substance of the electrode a binding species for orientation and chemical and reversible binding of the electroactive biological material to the electrode. The conductive substance may be particulate carbon, the binding species being provided by groups on the surface of the carbon particles by surface oxidation thereof. Alternatively the binding species may be provided by an additive which is dispersed throughout at least a portion of the conductive substance, optionally in the presence of a binder. The additive binding species may be non-ionic e.g. 4,4'-bipyridyl, or it may have an ionic functional group, for example it may be a fatty acid or fatty amine. The electroactive biological material is preferably cytochrome C. The bioelectrocatalytic processes of the invention include processes for the enzymatic oxidation or reduction of organic molecules, electroanalytical processes in which substances are monitored by means of the current or potential produced as a result of their interaction with an enzyme or cofactor and processes in biological fuel cells.

Patent GB-2113423-A (GB)
Title: Improvements in or relating to reservoir vessels
Inventor: JOSEPH STEPHEN HAMPDEN
IPC: B01J4/00
Filed: 1982-11-02
Abstract: A reservoir vessel for highly viscous liquids such as polyisobutylene. A perforated heated baffle spans the vessel close to an outlet located centrally at the bottom of the vessel, and the liquid is caused to flow preferentially through the perforations in the more peripheral parts of that baffle, so avoiding the natural tendency for the liquid to adopt a "pipe"-type flow as it approaches the outlet. The preferential flow may be created both by heating the peripheral parts of the baffle to a higher temperature than the centre and by the arrangement of the perforations themselves, for instance by forming larger or more closely-spaced perforations near the periphery, or by blocking the access of fluid to the central part of a baffle that is perforated all the way across. The invention also includes a method of dispensing a high viscous fluid flow from a vessel, in which preferential flow of the fluid toward the wall of the vessel is established shortly before the outlet is reached. <IMAGE>

Title: Locks
Inventor: NORTH MALCOLM
IPC: E05B39/02
Filed: 1983-09-15
Abstract: A lock includes a latching member 11 and a bullet catch 14. In the position shown the member 11 is in a locking position and extends within a catchplate of a door frame (not shown) and the bullet catch is held in a retracted position by engagement with the door frame. A tumbler lever 21 includes a downwardly projecting detent 24 which abuts a lug 25 on the carrier plate of the latching member 11 and prevents the latching member from moving to the unlocking position. The latching member may be moved to an unlocking position by a cylinder lock mechanism (not shown) mounted in a slot 27 or by an emergency mechanism including a peg 45. Both of these means for moving the latching member to the unlocking position first cause the detent 24 on the tumbler lever to be swung clear of the lug 25 before moving the latching member to the unlocking position. When the door is in the open position both the latching member and the bullet catch extend from the lock. Closure of the door cause both of these members to be pushed in before the latching member is pushed out into the catchplate of the door and the detent 24 of the tumbler lever swings down into the position shown. <IMAGE>

Title: Manufacture of optical fibre preforms
Inventor: NICHOLS BRUCE ARMSTRONG
IPC: C23C16/04
Filed: 1984-11-16
Abstract: In the method of making optical fibre preforms by a process in which a chemical reaction is caused to take place in a gaseous mixture passed radially through perforations (11) in a tube (3) towards a coaxially disposed glass surface (1) by means of a plasma column generated by a microwave generator (15), resulting in the deposition of a coating on said surface (1), the part of the plasma extending beyond the perforations can cause etching of the glass surface to occur, and impurities from this process are then carried into the deposition zone and thus contaminate the preform. By providing two microwave generators (15), one at each end of the apparatus, and by exhausting the deposition tube from both ends (2), this problem is overcome and a longer and more uniform preform can be made. <IMAGE>

Title: Improvements in operation of burners
Inventor: AMBROSE ROYSTON FRANK
IPC: F23L7/00
Filed: 1985-04-25
Abstract: Air is pumped at 7 through diffuser head 8 to rise as small bubbles 10 through water layer 3 and pass through a minor layer portion 4a of disturbed oil/water composition into a major oil layer portion 4. From this it escapes with low water content, and, it is surmised, a content of a catalyst species, probably .OH free radical. The escaping air passes from the convergent vessel top through an outlet 6 to the turbulent root of a burner flame. A small amount of such additive makes a large difference in flame shape and size, leading to a better performance of the boiler. <IMAGE>
