Title: Vacuum cleaning
Inventor: ASHBY DEREK
IPC: A47L11/30
Filed: 1984-02-16
Abstract: An improvement in the dry vacuum cleaning of soft and hard surfaces in which vacuum only is applied to such surface, is characterised in that dry soil flowing away from such surface under the influence of vacuum is sprayed with liquid and deposited in a wetted condition in a liquid and soil-collecting vessel. 
<??>Also proposed is apparatus for cleaning hard and soft surfaces by simultaneous application thereto of liquid and vacuum using a tool and which is equipped with a conversion device to permit dry vacuum cleaning with entrainment of dry soil in the liquid for subsequent collection in a soil and liquid vessel. The device comprises a 2-way valve (7) by which liquid flowing through a first pipe (5) can be caused to flow alternatively to a head (1) of a tool, or, through at least one branch pipe (9) to a second pipe (6) or pipe insert (11) by which suction is applied to the head (1) of the tool to entrain the dry soil flowing therein. The branch pipe or pipes normally terminate in one or more spray nozzles and may be located at various different positions in the path of flow of the dry soil induced by vacuum.

Title: Flux projector for use with composite photography
Inventor: TRUMBULL DONALD
IPC: G03B15/10
Filed: 1985-05-16
Abstract: The present invention provides a projector having particular application for use in front projection composite photographic systems. In particular, the present invention relates to composite colour photography, whether still, motion picture, or video in which foreground and background scenes are separately recorded and subsequently combined, using known "blue screen" or special background color techniques, to form a single image. The present invention includes a high pressure, short arc, mercury-xenon lamp in an optical system to produce a high intensity beam at wavelengths of either: 436 n.m. (blue); 545 n.m. (green); 589 n.m. (yellow) or 650+ n.m. (red). The selected color beam is then manipulated by optical elements into close correspondence to the viewing angle of a camera lens, and made coincident with the camera view by means of a beam splitter. Unwanted light is removed from the system through a "light trap" which traps and systematically absorbs incident light. The projected beam proceeds along the axis of the camera view to a retro-reflective projection screen, and returns therefrom along the same axis to the camera lens. Foreground subject matter interposed between the camera and the retro-reflective screen will therefore be combined with the image on the screen of the predetermined color, for subsequent compositing by methods known to the art.

In the other orientation the key can be inserted via the opening 16b, whereas the locking pin can be inserted via the opening 16a. Thus the device is usable in different mounting arrangements. <IMAGE>

Title: Over-current protection device
Inventor: BIANCO GIOVANNI
IPC: H01H1/58
Filed: 1986-10-09

Title: Moulding fibre-reinforced articles
Inventor: SLOMAN ROGER MARK
IPC: B29C63/02
Filed: 1987-01-15
Abstract: In a method of moulding fibre reinforced composite armour, one or more prepregs 12 of fibre reinforcement preimpregnated with a resin and hardener is/are laid on an article 10 to be armoured. The resin and hardener are capable of at least partial curing at a temperature below 80 DEG C. The prepreg is cured at a temperature not greater than 80 DEG C while applying pressure, to form an armour layer conforming to the surface of the article to be armoured. The use of the actual article as a mould for the prepreg ensures that the armour layer closely conforms to the article. The pressure is applied by means of a pressure differential across an impervious sheet 14. The armour layer can be permanently fixed to article 10 during the curing process by laying down an adhesive layer prior to laying down the (first) prepreg 12 or alternatively the armour layer can be removed after moulding and re-applied using adhesive and/or mechanical fastenings. <IMAGE>

Title: Determining optical fiber splice loss
Inventor: SO VINCENT CHOONG-YEONG
IPC: G02B6/24
Filed: 1987-04-02
Abstract: In the formation of a splice between two optical fibers 10 and 12, the splice loss is determined by locally supplying an optical signal to each fiber, in a direction towards the end to be spliced e.g. through a coupling 18, and measuring the signal levels P1 and P2 at the end of the fibers before making the splice, and using a symmetric detector 22 to measure in one of the fibers the signal levels D1 passing in one direction towards the splice and D2 in the opposite direction after passing through the splice, the splice loss being calculated from (P2-D2)-(P1-D1). Two forms of symmetric detector are described in which equal responses to optical signals in either direction in a fiber are obtained by bending the fibre and arranging a detector symmetrically with respect to the curve of the fibre. <IMAGE>

Title: Electronic device including uniaxial conductive adhesive and method of making same
Inventor: CLEMENT JAMES ROBERT
IPC: H01R4/04
Filed: 1987-04-14
Abstract: An electronic device is made by the method of connecting a circuit member (18) having a plurality of laterally spaced electrically conductive terminals (20) to a substrate (12) including a mounting surface (14) having a plurality of laterally spaced conductive paths (16). The method includes the steps of applying an adhesive (22) including a non-conductive resin and 20 to 25% by weight of conductive (e.g. metal) particles over the mounting surface of the substrate and mounting the circuit member on the adhesive while vertically aligning the conductive terminals over preselected ones of the conductive paths. The adhesive is non-conducting but when the content of the conductive particles in the adhesive is concentrated (e.g. by application of pressure) in the regions between each conductive terminal and the vertically aligned conductive paths to between 40 to 50% by weight the spacing between the metal particles is reduced thereby allowing conductivity through the resin and making the adhesive uniaxially conductive between each conductive terminal and vertically aligned conductive path, while the adhesive remains nonconductive between the laterally spaced terminals and conductive paths. <IMAGE>
