Title: Surge arrester
Inventor: DOONE RODNEY MEREDITH
IPC: H01C7/12
Filed: 1987-01-29
Abstract: A distribution class surge arrester comprises a core formed of distributed zinc oxide varistor blocks, aluminium blocks acting as heat sinks and as spacers providing voltage grading and required arcing distances, and terminal blocks held in face to face contact by means of a glass reinforced epoxy shell which is formed by winding a pre-preg onto the assembled blocks and thermally curing under mould pressure within an evacuated mould. The core is housed within a polymeric shedded housing which is formed by shrinking a heat-shrink shedded sleeve onto the core with a sealant provided in the interface of the core and the sleeve, and end caps are sealed to the ends of the structure thus formed. The all solid-state arrester thus formed has performance and cost advantages over conventional porcelain housed arresters and furthermore has very considerable physical strength enabling it to serve additionally as a stand-off support insulator in situations where con­ventionally separate arrester and support insulators were required.

Title: Assay for polynucleotides
Inventor: HIRSCHFELD TOMAS B
IPC: C12Q1/68
Filed: 1987-03-13
Abstract: An assay for polynucleotides employing total internal reflection of excitation radiation at a coating 32 bonded to the surface of a total internal reflection cell 22. The coating initially includes single-stranded polynucleotides coupled to individual attachment sites on the surface of the cell, such polynucleotides being complementary, at least in part, to the single-stranded form of the polynucleotide that is being assayed. Each molecule of the coupled polynucleotide is connected to the cell surface through a spacer connected to an irreversibly conjugated polyadenine/polythymidine sequence at one end of the coupled polynucleotide. When the surface of the coated cell is contacted with a sample that contains single-stranded polynucleotide complementary to the bound polynucleotide, renaturation will occur, forming a double- stranded form of the polynucleotide of interest. A fluorochrome dye specific to that double-stranded form is coupled to the latter, the dye including a chromophore that the excitation radiation will excite into fluorescence. The induced fluorescence is then gathered and measured at 43. <IMAGE>

Title: Improvements in gas fires
Inventor: BROADBENT MARK ANDREW
IPC: F24C3/00
Filed: 1988-02-23
Abstract: A coal/log-effect gas fire, of the kind in which there is a porous bed 12 and gas or gas/air mixture can enter a tray 10 in which the porous bed is provided and percolate upwardly through the porous bed, includes a fire-resistant fibrous pad 40 located so that the gas or gas/air mixture passes through it before escaping through the porous bed. In this way, a silencer for the gas or gas/air flow is provided, and this effects a significant noise reduction. The invention also provides a special gas nozzle opening into a mixing chamber with a sleeve surrounding the nozzle and extending beyond the open end of the nozzle. In this way air is effectively prevented from mixing with the jet of gas escaping from the nozzle until the jet passes the end of the sleeve thereby reducing the energy which is released from the gas/air mixture on combustion below the optimum level. This is required in order to obtain the best coal/log effect in the flames of the fire. <IMAGE>

Title: Laser beam deflector comprising two reflectors
Inventor: BAILEY GAVIN RICHARD
IPC: G01B9/02
Filed: 1990-06-15
Abstract: A laser beam 22, e.g. from a laser interferometer, is deflected along path A or path B by a deflector 24. The deflector comprises two plane mirrors (140, 142, Fig 4), one of which (142) is rotatable on a shaft about an axis perpendicular to the beam to enable adjustment of the angle through which the beam is deflected. By maintaining the angle between the beams and the surfaces of the mirrors at an angle greater than the angle through which the deflector deflects the beam, the comparatively small mirrors (140, 142) combine to deflect the beam 22 through a shallow angle which would otherwise require a large single mirror. A retro-reflector 26 on the head H may be oriented by a probe head 28 to ensure the light beam 22 is always received by the retro-reflector 26 within its acceptance angle. <IMAGE>
