Title: Screw adjuster
Inventor: EDELSTEIN DAVID ANDREW
IPC: B66F3/08
Filed: 1984-02-27
Abstract: A screw adjuster comprises a tube (3) with an internal screw-thread with which an externally screw-threaded rod (7) is engaged and an operating handle or lever (10) comprising a pair of slotted arms (11, 12) pivotally mounted on the tube (3) by means of pins (14) which are located in the slots of said arms (11, 12). The ends of the arms (11, 12) are connected together by arcuate bridge elements (15) which extend in opposite directions and which are engageable with the tube (3) when the arms are located in a stowage position in which they extend substantially parallel to the longitudinal axis of the tube as shown in the drawing. The arms can be pivoted from this position to an operative position in which they can cause rotation of the tube (3). The tube (3) is mounted for rotation in bearings (4) in lugs (5, 6) on base (2). <IMAGE>
Patent GB-2147060-A (GB)
Title: Seals for rotary members
Inventor: POTTER CHARLES WILLIAM
IPC: F16J15/32
Filed: 1984-02-27
Abstract: A seal arrangement is provided between a first inner part such as a shaft having an outer surface (9), and a second outerpart comprising a casing (1), there being relative rotation between the parts, in particular rotation of the casing (1) about the shaft Fig. 1 (not shown). The seal arrangement includes a seal member 25 pressed against the shaft surface (9) by a garter spring 21. (In the embodiment of Fig. 2 the spring 21 acts through a flexible seal support 23). The spring 21 is restrained from increase in its circumferential length due to centrifugal force when rotated by a restraint in the form of an encasing rubber annulus 22 which has been moulded to enclose the spring 21. In the alternative embodiment of Fig. 1 (not shown) the restraint is in the form of a spring-receiving annular recess in an elastomeric or plastic spring support. The recess has indentations which engage between adjacent convolutions of the spring, such engagement preventing the spring from distending. In a further embodiment an endless wire is located within the garter spring to restrain its distention. <IMAGE>

Patent GB-2145897-A (GB)
Title: Stereoscopic display
Inventor: PUND MARVIN LOUIS
IPC: G02B30/25
Filed: 1984-07-25
Abstract: A display system is provided which gives an illusion of depth to an observer by generating left and right eye image projections for view by the observer. The system includes an observer tracking system which monitors the position of the observer and accordingly adjusts the projected scene perspective by adjusting apertures 21, 22 (mounted side by side) so that the two images from displays 12, 13 are projected onto respective eyes of the observer. Filters 15, 19 polarise light passing through them in orthogonal directions and apertures 21, 22 are correspondingly polarised sheets. The observer tracking system 10 may include arrays of photosensitive cells or two parallel mounted video cameras. The system is particularly described for use in a video arcade game but may also be used in an aircraft cockpit or domestic environment when the apertures comprise matrices of liquid crystal shutters and the two displays may project images of different programmes (Figs. 5-9 not shown). <IMAGE>

Title: An oil discrimination technique
Inventor: BATHER JOHN MAXWELL
IPC: G01N21/33
Filed: 1984-11-01
Abstract: Oil-based drilling fluid is analysed for presence of indigenous formation oil. A well sample, derived from returned mud, core or cuttings, is subjected to ultra-violet radiation and a parameter related to absorbance, transmittance or emittance at selected wavelengths is measured. This parameter is compared with a like parameter at the same wavelengths for the base oil of the drilling fluid. Preferably, absorbance is used, and the comparison is effected by solution of simultaneous equations defined in the description.

Title: Light scattering coatings
Inventor: CAIRNS DR JAMES ANTHONY
IPC: C03C17/00
Filed: 1985-11-11
Abstract: A glass surface, for example of a glass article such as a glass, electric light bulb is provided with a surface coating for endowing the surface with light scattering properties by (i) applying a precursor (e.g. a silica precursor) for a coating material, then (ii) treating the precursor to form an adherent coating. In step (i), the precursor also contains a second material convertible under the conditions of step (ii) to give a light scattering phase in the coating. The second material may be a salt (e.g. NaHCO3 or CH3COONH4) decomposable in step (ii) to a gaseous product to generate pores as the light scattering phase. Alternatively, the second material may be a salt (e.g. NaCl) that is provided in solution in step (i) and is crystallisable in step (ii) to generate light scattering crystals in the coating.

Patent GB-2176581-A (GB)
Title: Control of fluid flow
Inventor: SPRINGER GERALD ALFRED JOHN
IPC: G05D7/01
Filed: 1986-04-25
Abstract: A valve assembly 30 comprises control means responsive to supply of fluid to a control inlet 45 to operate valve means 39 in a main passageway 32-35. It is used in the preferred embodiment to control the rate of flow of water to a cistern (23, Fig. 1) in an automatic flushing system with respect to water usage in a supply line (11) to other appliances (12) and which is affectively independent from the supply line (21) leading to the cistern. A control valve (60) in the other supply line (11) delivers a flow of water to control inlet 45 via a control line (25) when water flows in line (11) to an appliance (12). Main inlet 35 of valve 30 is connected to line (21) and a diaphragm 42, or a piston, responds to flow of water in the control line to move valve 39 to allow flow, or increased flow, of water through main passageway 32-35 to the cistern from line (21). The rate at which the cistern flushes may thus be controlled with reference to the usage of hot water at hand basins. In a second embodiment a main valve means (160, Fig. 4) incorporates an auxiliary poppet valve (167) which acts as a pilot valve to effect opening of valve (160) when water flows to a control inlet (145). <IMAGE>

Title: Electrochemically degrading organic contaminants in groundwater
Inventor: BELLAMY KEVIN L
IPC: B09C1/00
Filed: 1987-01-08
Abstract: A process for electrochemically degrading organic contaminants in groundwater comprises embedding a grid work of rods in the ground in the region where groundwater flows which contain the organic contaminants. A voltage is applied to the plurality of space-apart oppositely charged rods to degrade electrochemically such organic contaminants in the groundwater. Sufficient voltage is applied across the plurality of oppositely charged rods to effect such electrochemical degradation. The process provides an effective relatively inexpensive form of minimizing or eliminating organic contaminants in groundwater, particularly contaminants such as phenols and trichloroethylene.
