Patent GB-2187050-A (GB)
Title: Vibration resistant electrical coupling
Inventor: FOWLER CLIFFORD C
IPC: H01R13/622
Filed: 1987-02-09
Abstract: A connector accessory for electrical connectors containing a detent or locking member or members for preventing disconnection from an attached connector when the assembly is subjected to vibration, shock or other stresses. The accessory consists of a coupling and a body containing the accessory which in one form is a detent and in another form serves as a detent in one direction of rotation and a permanent or temporary lock in the other direction of rotation. The coupling is provided with screw threads to engage an accessory thread at the rear of an electrical connector and the body contains features which are required to provide proper mechanical and environmental interface characteristics to mate with various electrical connectors, i.e., teeth, splines, seals, etc. When the accessory is mated to an electrical connector, the rotation of the coupling is restricted by a spring and tooth mechanism interfacing between the coupling and the body to prevent the coupling from counter-rotating and allowing the accessory to become loosened or separate from the back of the connector. This concept may also be employed on a connector coupling ring as well.
Patent GB-2190929-A (GB)
Title: Refractory composite bodies
Inventor: PARTRIDGE GRAHAM
IPC: C04B35/80
Filed: 1987-04-30
Abstract: A method of making refractory composite bodies consisting of glass-ceramic, glass, ceramic or carbon fibre embedded in a refractory matrix. The matrix is formed by coating the fibre with a sol, winding the coated fibre on to a mandrel and heat treating the composite mass to produce a sol-gel and finally a refractory matrix. The component so made may be used as an insulator or a mechanical member, for example a cylinder liner. The sol is prepared by hydrolyser of a metal salt, metal alkoxide, silica forms or silane. By use of a square section mandrel flat laminae can be produced which are plied up to form a multilayer multiangle or unidirectionally reinforced composite.

Inventor: WOOD ALFRED
IPC: D01G15/46
Filed: 1987-06-12
Abstract: The doffer unit of a carding apparatus includes a doffer 1 cooperating with a fluted stripper roll 2 from which the carded web 5 is stripped means of a blade 13 and laid on the upper surface of a stationary support plate 4 which guides the web to a condensing belt arrangement 6. The web is detached from the roll 2 to move along a first direction and then carried along a second direction transversely of the first direction by the moving belts 6. Other laterally moving condensing surface including web dividers may alternatively be used. Traditionally a driven roller has been used to support the web 5 on its way to the belt system 6. Yet the stationary support plate 4 reliably operates the unit. The blade 13 which is made of steel is removably inserted in a support bar 3 carrying the plate 4 whereby when one edge surface of blade 13 wears the blade is repositioned. The belt arrangement can be moved to the dashed line position to allow inspection of the web. The bar 3 can likewise be moved for maintenance work. <IMAGE>
Patent GB-2207815-A (GB)
Title: Process for producing a programmed matrix
Inventor: KIRBY PETER LINLEY
IPC: H05K1/09
Filed: 1987-07-16
Abstract: A programmed matrix device is produced by forming a first layer (1) of conductive tracks on an insulating substrate (2). A dielectric second layer (3) of organic photoresist material is applied over the first layer (1), and dots (5) of a material opaque to actinic radiation are applied to the dielectric layer (3) to overlie selected tracks of the first layer (1). After exposure to actinic radiation, the dot-providing material and the unexposed material of the second layer underlying the dots (5) are removed with a solvent, leaving apertures through the second layer accessing the selected tracks of the first layer. A third layer (7) of tracks of electrically conductive polymer material is provided over the second layer (3) and non-parallel to the tracks of the first layer (1), such that the track material of the third layer (7) passes through the apertures in the second layer (3) to interconnect selected tracks of the first and third layers and define a selected code or bit pattern. <IMAGE>

Title: Manufacture of mineral insulated cables
Inventor: FILLER EDWARD ALBERT
IPC: H01B13/004
Filed: 1990-08-17
Abstract: Apparatus and a process for manufacturing mineral-insulated cable (10) has seam-welding heads for welding a travelling strip simultaneously at two or more spaced points (F1, F2, F3) to form a tubular sheath for the cable. Powdered insulating material and at least one conducting wire are introduced into the sheath and the whole is reduced. The spacing between points F1 and F2 may be increased to allow enough cooling of the weld to enable the welding head at F1 to reduce any thickening of weld. In another aspect of the invention, in start-up or shut-down of a process for manufacturing mineral-insulated cable wherein a strip is seam-welded to form a tubular sheath for the cable (10), the same quality of seam-weld (100) is ensured as for the steady state condition by controlling the arc current and voltage as a function of the speed of conveyance of the strip. <IMAGE>

Title: An apparatus for gas atomising a liquid
Inventor: CHRISTODOULOU MARIOS SAVA
IPC: B22F9/08
Filed: 1991-05-01
Abstract: An apparatus (110) for atomising a molten metal to produce metal particles or droplets comprises an annular atomising nozzle (112) which defines an opening (114) through which molten metal flows. The annular atomising nozzle (112) has an annular gas manifold (116) which receives gas from a gas supply. A plurality of apertures (10) extend through the atomising nozzle (112) to direct gas from the gas manifold (116) to intersect the axis of the annular atomising nozzle (112). Instead of the apertures in the atomizing nozzle having sharp edged inlets each aperture is provided with a smooth or contoured inlet end to produce a streamlined flow of atomizing gas from the annular gas manifold 116 into the aperture 120 so that the jets of atomising gas issue from the aperture 120 at a uniform flow rate. The inlet ends (142) of the apertures (120) preferably have a bell mouth shape in cross-section such that the jets of atomising gas issue from the apertures (120) at a uniform flow rate. The apertures (120) are machined to accurate tolerances. This produces more symmetric, predictable and repeatable flow of metallic droplets, or particles, onto the substrate (130) to form an article (132). The apparatus may be used to coat articles with metal. <IMAGE>
