Title: Umbrella rib linkage system
Inventor: OKUDA TOSHIO
IPC: A45B19/00
Filed: 1984-11-23
Abstract: A rib linkage system of the topless type comprises stretcher ribs 30 to connect the umbrella's runner 18 with each cover rib 25, support ribs 42 to connect the umbrella's ferrule 17 with each stretcher rib 30, and control links 52 to connect each support rib 42 with its associated cover rib 25. The connection of the support rib 42 with the stretcher rib 30 is by means of a split or bifurcated brace structure 57, 60 that enhances the stability of the linkage system when the umbrella is full opened. The control link 52, support rib 42, stretcher rib 30, and cover rib 25 all cooperate to define a generally parallelogram configuration beneath the stretcher rib when the umbrella is in between its full opened and full closed positions (Fig. 2), and to define a generally triangular configuration when the umbrella is full opened Fig. 1., again to enhance the stability of the linkage system when the umbrella is opened and also to permit the umbrella to collapse into a short and compact storage or full closed position (Fig.3). <IMAGE>

Title: Fireproof panel
Inventor: GIRAUD CHRISTIAN
IPC: C04B28/20
Filed: 1984-12-06
Abstract: A fireproof panel comprises a mixture of reinforcing fibres, a hydraulic binder and mineral fillers. The reinforcing fibres are cellulose fibres of coniferous trees obtained from a chemical paste of the bleached Kraft type. Panels having a thickness greater than 50mm may be prepared by suspending cellulose fibres in water and forming a aqueous paste containing the cellulose fibres, a hydraulic binder and mineral fillers. The moist paste is deposited continuously in a layer on a moving filter member, is partially dehydrated and wound around a roll until the desired thickness is obtained. The roll obtained is then cut and unrolled and the hydraulic binder is allowed to harden.

Title: Spectral beam splitting interferometer
Inventor: PERKINS CHARLES VINCENT
IPC: G01J3/453
Filed: 1985-02-27
Abstract: In beam splitting interferometers for use in Fourier transform spectrometers working in the infra-red region from 2.5 microns to 50 microns wavelength, it is impossible to provide a single beam splitting assembly which is efficient over the whole wavelength range, due to the limitations of available materials. In a set of interchangeable beam splitters it is difficult to ensure sufficiently accurate registration of each beam splitter after a change. The invention provides a set of beam splitters 4,5 held stationary in separated locations and radiation directing means 2, 3, 26, 28 which passes an input beam 12, 13 through a beam splitter, which selects the recombined beam 23 or 24 emerging from a desired beam splitter, and which passes it to a detector 25 in a fixed location. Beam splitters 4,5 each function in a different part of the spectrum of the source 1, and each produce two subbeams 14 and 16, 15 and 17. The difference in path length of the two subbeams is variable at 7,8. <IMAGE>

Title: Automatically and accurately positioning a workpiece
Inventor: WINTERFORD CHARLES RAYMOND
IPC: B23Q15/22
Filed: 1986-01-18
Abstract: A method of automatically and accurately positioning a first workpiece in a set position relative to a second workpiece (11) comprises the steps of engaging a tool (22) with the first workpiece, moving the first workpiece and tool to a datum position, receiving light from the second workpiece and the tool in an electronic camera (30), electronically analysing the signal produced by the eletronic camera to accurately determine the position or relative position of both the second workpiece (11) and the tool (22), and moving the first workpiece to the set position so that any inaccuracies in the movement of the tool (22) can be monitored. The sensing by the camera is improved by a reflector to receive light reflected from (Fig. 5) or just missing (Fig. 6) the edge of the first workpiece, or by a filter to single out a bright spot produced by reflection from that edge (Fig. 8). <IMAGE>

Title: Domestic weather information display apparatus
Inventor: LIM JIT YONG
IPC: G01W1/06
Filed: 1986-02-11
Abstract: A first brightness detector in the form of a light dependent resistor is electrically coupled to an analyser which energises a green light if the light intensity sensed is high enough to represent sunny conditions, an amber light if the light intensity sensed is only high enough to represent cloudy conditions, and a blue light if the light intensity is low enough to indicate night time darkness. A rain sensor in the form of a funnel above a pair of spaced electrical contacts, when short-circuited by a rain drop, triggers a rain detector circuit which then energises a red light for a predetermined duration. A second brightness detector, also in the form of a light dependent resistor, is electrically coupled to an electrically driven meter M1 having a pointer moving over a scale divided into differently coloured bands or sectors representing darkness, cloud, and sunlight. <IMAGE>

Abstract: A lifting appliance for loading and unloading the drum of a centrifuge with cylindrical packages (1) of textile material placed one onto the other to form columns (2), and which reaches in as far as the lower end of the central cavity of each columns. The appliance has an end piece (14), which is provided with radially-protrudable ring segments (28). An axial shaft (12), when rotated by a lever (17), causes double levers (30) to force the ring segments beyond the radial extent of a tubular centre piece (13) of the appliance and frictionally engage the inner surface of the lower package (1), which is sufficient to transfer the total weight of a column (2) onto the lifting appliance (6). The lever (17) is held in position by a stop pawl (20) mounted in a supporting lever (18). The packages are removed from the centrifuge by the appliance lifting a centre plate of the centrifuge drum and by then removing the packages layer by layer. The ring segments may have depressions or projections on their convex outer sides. <IMAGE>

Title: Engine for v.t.o.l. and other aircraft
Inventor: BIRKETT HAROLD
IPC: F02C3/08
Filed: 1989-03-16
Abstract: . For vertical take off and landing and low speed flight, air is induced into the front and rear ends of an engine duct and expelled into an annular power unit including combustion chambers surrounding the engine duct. The ejected jet stream from the annular power unit is vectored (via suitable ducting) over air foils to generate lift which is also generated by the reactive forces of the ejected jet streams. Manoeuvering is achieved by vectoring ejected jet streams and also by varying the flow of air into the front and rear of the engine duct. Transition to forward flight is achieved by opening the rear outlet of the annular power unit whilst closing the V.T.O. outlets until finally all gases are ejected rearward to give forward thrust. <IMAGE>
