Patent GB-2174808-A (GB)
Title: Electrochemical assay for cis-diols
Inventor: HILL HUGH ALLEN OLIVER
IPC: C07F17/00
Filed: 1986-02-21
Abstract: The invention disclosed relates to an electrochemical assay which is particularly concerned with an assay for the presence of, or amount of, glycosylated haemoglobin in a blood sample, but which extends a general assay for detecting the presence of, monitoring the level of or determining the concentration of compounds containing cis-diol groups, such as glycols, nucleic acid components, sugars, polyols, catechols and glycosylated proteins.When ferrocene boronic acid or a derivative thereof is present free in solution, it can act as a mediator for a wide range of oxido-reductases. Howeverin the presence of, for example. sugars containing the cis-diol structure, the metallocine (such as ferrocene boronic acid) covalently binds to the sugar. When the ferrocene boronic acid is thus bound, it is essentially immobilized and its properties as a mediator and ability to diffuse will be markedly affected.

Title: Solid fuel transfer and seal system
Inventor: WINKIN JUSTIN P
IPC: F23K3/16
Filed: 1986-03-10
Abstract: A solid fuel transfer and seal system in which a seal chamber receives a fuel material and a valve 30 is provided for opening and closing a discharge opening 14B in the seal chamber 14. A seal plug unit 22 moves across the chamber to push the fuel material contained in said chamber towards the discharge opening. The valve 30 is opened in response to a predetermined amount of movement of the seal plug unit 22 towards the discharge opening, e.g. as determined by limit switch 40, and the seal plug unit seals the inlet opening 14A from the discharge opening after opening of the valve. A level limit switch or metering device associated with inlet conveyor 24 or chute 26 measures the amount of fuel in chamber 14 and triggers movement of unit 22; further limit switches 42 and 44 define its limits of travel. <IMAGE>

Title: Depression and elevation angle adjustment device for electric fan
Inventor: HASHIMOTO YOSHIKI
IPC: F16M11/10
Filed: 1987-01-07
Abstract: A depression and elevation control device for an electric fan has a twisted spring 51 which during elevation or depression is arranged such that forces in the spring always cause it to be moved towards the contracting direction of its diameter and thus provide a counter balance for the weight to the fan. The spring has end portions 51a, 51b one of which acts on the edge 47a of a cutaway in plate 47 surrounding the pivot and the other is either acted on by the spring stopping plate 48 or the neckpiece 9 respectively depending on the direction of movement.

Title: Plastics clamping strap device
Inventor: JUNEMANN DIETRICH
IPC: F16L3/233
Filed: 1987-03-12
Abstract: A plastics clamping strap device for embracing and holding cables, pipes and bunches of cables has an integral fixing portion (2) for press attachment to a connector pin, such as a screwthreaded pin or bolt, and a clamping strap portion (1) formed at the lower end of the fixing portion (2). The strap portion (1) is provided with uniformly spaced transverse portions (5) arranged transverse to the direction of the strap portion having a hook-like cross-section and which are engageable with a latching hook (7) also formed on the fixing portion (2). The transverse portions (5) are provided with retaining edges (6) which face towards the fixing portion (2) and which project above the strap portion (1) by an amount corresponding to the head height 'k' of the latching hook (7) so that the retaining edge (8) of the latching hook (7) can be pushed under the retaining edge (6) in the engagement operation. In addition the open gap 'd' between the retaining edge (6) of a transverse portion (5) and the rear wall (9) of the next following transverse portion (5) is somewhat smaller than the width 'b' of the head of the latching hook so that although the latter may be pressed into the passage 'd' by the application of a light force, it cannot be released again of its own accord after engagement of the hook (7) in to the retaining edge (6). <IMAGE>

Title: Digital timepiece
Inventor: CARR RICHARD
IPC: G04G9/08
Filed: 1987-07-29
Abstract: A digital timepiece has a set of figures 21 representing 'hours' and a set 22 representing minutes. An indicator is provided to distinguish a display of 'minutes past the hour' from 'minutes to the hour'. In the preferred embodiment, as shown in Figs. 1 and 2, the hour and minute figures are interchangeable and the indicator 25 is a letter and located adjacent to each set of figures. Only one letter 'm' is illuminated to indicate that the adjacent set represents the 'minute' set. Alternatively, the letter is an 'h' indicating the hour set. In a modification the indicator distinguishes the 'minutes' from the 'hours' by size or colour. In another modification the hour set is located between two 'minute' sets, only one of which is illuminated to indicate minutes before the hour or minutes after the hour. In a further modification, Fig. 3 words such as TO and PAST are located between a minute set on the left and an hour set on the right and the words are selectively illuminated to display minutes to the hour or minutes past the hour. <IMAGE>

Title: Shutter door assembly
Inventor: MCILWRICK GORDON
IPC: E06B9/17
Filed: 1987-08-03
Abstract: A shutter door assembly (10) e.g. a fire door comprises a shutter door (11) and a door frame structure (12), the shutter door (11) being formed of a plurality of laths (13) pivotally attached to each other in edge-to-edge formation to form a curtain (20) suspended from a barrel (16) mounted in end plates (15). When the curtain (20) is lowered to the door closed position a catch rail (21) extending along one lath (19) engages a suspension rail (18) extending along an upper member of the door frame structure (12) such as a lintel (14), so that the curtain (20) is suspended on the suspension rail (18). The barrel (16) and end plates (15) are not under great stress when the door (11) is closed under fire conditions and the engagement of the catch rail (21) and suspension rail (18) forms a built-in smoke barrier. A rigidly or resiliently mounted pusher 24-26 ensures engagement of the rails 21. The arrangement ensures that an authorising test on a narrow assembly is representative of a wider, full-scale assembly. <IMAGE>
