Title: Collapsible builders' staging for roofs
Inventor: REYNOLDS EDWARD TERRY
IPC: E04G3/26
Filed: 1988-03-03
Abstract: A collapsible builders' staging is provided for use on a pitched roof to eliminate the need for complex scaffolding erected about a chimney stack in need of repair. A staging unit comprises a base member (1), an upright (12), and a slidable collar (8) pivotally connecting an end of the upright (12) to base (1). A tie (15) connects the base (1) and the upright (12). Each end of the tie (15) is pivotally connected to a respective one of the base (1) and upright (12). The staging unit can be moved between a collapsed configuration in which the base (1), tie (15) and upright (12) are substantially parallel and an erect configuration in which, with the base (1) extending down the pitch of the roof, the tie (15) is substantially horizontal.

Title: Detecting coherent radiation
Inventor: SCADDAN RICHARD JAMES
IPC: G01J1/42
Filed: 1988-09-01
Abstract: A laser radiation detector monitors the intensity of three portions of an incident beam which are subjected to three different filter functions. The radiation reflected and transmitted by an interferometer 16 is monitored to give two filter functions. A third filter function may be obtained by monitoring the radiation transmitted by a further interferometer 14. Processor 32 signals a laser radiation alarm of the outputs of detectors 22, 24, 30 are not substantially the same or alternatively processor 32 may respond to changes in the differences between the outputs of the detectors. In an alternative arrangement (figure 4, not shown), the third filter function may be obtained by making the interferometer of birefringent material and separating the polarisation components transmitted through the interferometer, to give an additional filter function. <IMAGE>

Title: A toy vehicle
Inventor: KAMIKAWA HIRO
IPC: A63H17/40
Filed: 1988-10-13
Abstract: A toy vehicle, when halted by an obstruction, turns and proceeds in another direction. The vehicle includes an axle 7 to which wheel 8 is secured and to which wheel 10 is clutched through pawl/ratchet 11/9. An inertia wheel motor in a cage 16 normally drives the axle 7 through gear 18. The cage 16 is weighted at 26, 27 to normally hang in the position shown. When an obstruction prevents rotation of axle 7, the cage 16 rotates and/or oscillates around the axle, this movement together with the action of pawl/ratchet 11/9 causing the vehicle to turn away from the obstruction. <IMAGE>

Title: Ring laser gyroscope scale factor error control apparatus and method
Inventor: KANESGBERG EDWARD
IPC: G01C19/66
Filed: 1988-10-27
Abstract: The intensity and frequency variation due to retroscatter in a ring laser gyroscope are determined and used to correct the gyro scale factor. The orthogonal types of scatter due to dielectric variation and due to height variation, which lead to common mode phase delays of 0 and Ï/2 respectively are taken into account in calculating the correction to the scale factor. The scale factor errors are determined in terms of observable quantities. Scale factor error control is accomplished by extracting a portion of both of the two counterpropagating light beams and measuring their respective intensities at 50, 52, creating intensity modulation indices representative of the sum and difference intensities, using closed loop control of the real-time difference between the intensities of the beam in the ring laser gyro to reduce scale factor variation using pushâpull mirror control of at least two mirrors 18, 21. The residual error after pushâpull mirror control minimization is output for use by a navigation system computer.

Title: Making printed circuits
Inventor: LOWE JOHN MICHAEL
IPC: H05K1/16
Filed: 1988-12-24
Abstract: A first conductive layer on a printed circuit board is separated from a superincumbent second layer by an insulating polymer layer. The arrangement may form a cross-over, a capacitor or a keyboard. The first conductive layer may be formed from a laminated copper foil by etching or may be screen printed using a conductive ink. Other methods such as transfer printing, lithography, air brush or hand brush may also be employed. The polymer layer and the second conductive layer may be deposited by screen printing. The conductive layers may be protected from corrosion by a carbon-containing ink which also acts as a solder resist during the attachment of other circuit components. Resistors may be deposited by screen printing, and the printed layers may be cured by heat or UV light. The invention may be used to make multi-layer circuits with up to 50 layers, including conductive ground layers to provide RFI shielding. The circuit substrate may be synthetic resin bonded paper, or the circuit may be formed directly on a car dashboard, radio case, heatsink or the like.

Title: A Disc cassette assembly
Inventor: LAM PHILIP YUNG TAK
IPC: G11B23/03
Filed: 1989-02-28
Abstract: A disc cassette assembly comprising an outer housing 3 and an inner housing 2 in which a recording disc is rotatably mounted, each housing including a central first aperture for access to the disc of a drive means and a second aperture (29a) 29b (31a) 31b (eg Fig 1) for access to a surface of the disc of a write or read head of a record and/or play back apparatus. The inner housing is rotatable about an axis coincident with the axis of rotation of he disc, between a first limit position and a second limit position, so that rotation of the inner housing into its second limit position occurs against the bias of a resilient means to bring the respective second apertures into line. The inner housing is rotated automatically to 'open' the second apertures upon insertion of the cassette assembly into the record and/or playback apparatus, and removal of the cassette assembly from the apparatus causes rotation of the inner housing to its first limit position, under the force of the resilient means, to 'close' the second apertures. Rotation of the inner housing may also operate a shutter (4a) (4b) 5a, 5b to 'open' and 'close' the first apertures in the housings. The cassette comprises seal strip 16 (also Figs. 1, 10, 12, 18 for example), seal strip clip (21) being pushed by member 42 upon cassette insertion to disengage clip 22 and seal strip 16 moved to cause inner housing 2 to rotate via spurs 13 and the shutter to open. The disc hub has conductive plate 9 and connecting rails 10a, b whereby the drive unit can identify the correct drive shaft position. Springs (11a) 11b (Fig 6) stabilise the record disc. Liner membrane (12) is provided and read/write ID button (36) is detailed (Figs 13-17). <IMAGE>

Title: Tool sharpening apparatus
Inventor: LACY GRAHAM KEITH
IPC: B24B3/26
Filed: 1992-03-04
Abstract: Edge tool sharpening apparatus for the sharpening of an edge tool comprising a shank (e.g. a wood drill bit), said apparatus comprising: an axially rotatable abrasive element having a peripheral abrasive surface, and support means comprising support surfaces to support the shank of the tool such that its face to be sharpened engages the abrasive surface with the shank axis at an acute angle to the diametral plane of the rotatable abrasive element through the engagement location, said support means providing for automatic compensation for different shank diameters of different drill bits, when supported by the same said support surfaces, by automatically effecting an increase in the inclination of said diametral plane with increase in the diameter of the shank and such that said acute angle is substantially constant for a range of drill bit shank sizes. Advantageously, for sharpening a wood drill bit, the apparatus comprises means for positioning the support means such that a wood drill bit supported thereby can engage the abrasive element with a main clearance face of the wood drill bit in sharpening engagement of the element's peripheral surface, the diametral plane of the abrasive element through the engagement location being inclined to the drill bit's shank axis at substantially the clearance angle of the clearance face, and simultaneously also with a preliminary indenting face of the central nib of the wood drill bit in sharpening engagement of the element's lateral surface.
