Patent GB-2315940-A (GB)
Title: Radar
Inventor: VOLES ROGER
IPC: G01S13/24
Filed: 1985-07-11
Abstract: A radar transmits pulses in accordance with a monotonic sequencies of frequencies and subjects the corresponding returns to a Fast Fourier Transform, in circuit 19, to derive a plurality of transformation signals representing a distribution of pairs of radar scatterers (target and or clutter) as a function of their differential range. A control circuit (13) is used to control the frequency sweep period so as to emphasise the effect of a target in said plurality of transformation signals as compared with the effect of clutter.

Title: Planks for temporary roadway or pavement barrier systems
Inventor: LEES ANTHONY
IPC: E01F13/02
Filed: 1986-02-24
Abstract: A barrier plank (19) for a roadway has triangular section ridges (22) extending across the plank at spaced locations along the length of the plank. Each ridge provides a facet (23) facing at an acute angle to the plank in one direction and a corresponding facet (24) on the other side of the ridge facing at an acute angle along the plank in the opposite direction. Facets (23) have red retro-reflective surfaces and facets (24) have white retro-reflective surfaces. Thus light directed from a vehicle at a shallow angle onto the barrier plank will be reflected back by the facets (23 or 24) according to the direction of approach so the plank will be readily visible to the driver. Between the ridges the plank has alternate red and white reflective surfaces (26, 27) to reflect back light directed at normal or near normal angles to the plank. <IMAGE>

Title: Apparatus for measuring distances and angles
Inventor: BENNISON ROGER
IPC: G01C3/10
Filed: 1986-06-06
Abstract: The apparatus comprises means for projecting first and second beams of light, an arrangement for inclining one beam relatively to the other, means for measuring the inclination and further means for imparting angular movement to one of the beams about an axis lying in the plane containing the beams and for measuring the movement. One embodiment comprises a housing (2) accommodating a laser (1). Positioned in the path of the laser beam (3) is a beam splitting mirror (4) which divides the beam along two separate parts (5, 6). One part (5) emerges from the housing via an aperture (7) while the other part (6) is reflected by a reflector (8) through a slot (9) in the housing. Reflector (8) is mounted for pivotal movement. Distances are measured by directing part (5) towards an object and then rotating reflector (8) until coincidence on the object is obtained. Part (2a) of the housing is rotatable to allow angular movement of the one beam (5). <IMAGE>

Patent GB-2236767-A (GB)
Title: Wool dyeing
Inventor: WELHAM ARTHUR CHARLES
IPC: D06P3/16
Filed: 1989-10-09
Abstract: A process for dyeing wool fibres (preferably in the form of a yarn) comprising applying to the fibres 0.1-1.5% (based on the dry weight of wool present) of an oxidising agent before or at the same time as applying one or more dyes selected from acid dyes, chrome dyes, reactive dyes and metal complex dyes. The oxidising agent may be an alkali metal or alkaline earth metal chlorate, bromato or iodate, preferably sodium bromato optionally catalysed with sodium metavanadate. Dyeing pH may be 5 to 7. The process alleviates the problems of unlevelness and uneveness of dyeings produced by package dyeing, and the treated fibres give good results in relaxation tests, and are suitable for making carpets and woven or knitted goods.

Abstract: A tool which may be used with other similar tools for the temporary positioning of a board on a substrate 16 to which it is being permanently attached comprises an elongate member 10 fixable to the substrate and carrying partway along its length an annular support 12. As shown, the elongate member is a hollow shaft through which a nail, screw or the like may be passed to fix the tool to a substrate, and the support is spaced from one of its ends by the thickness of a board to be supported. The spacing of the support from opposite ends of the elongate member may be different for use with two different boards. The elongate and support members are of mild steel and welded together. In another arrangement the outer surface of the elongate member is threaded to engage a threaded aperture in the support so that its position on the elongate member may be varied and the elongate member is formed at one end with an axially extending spike and at the other end with a head such that the spike may be driven into a substrate with a hammer. In either arrangement the diameter of the elongate member is selected to enable a predetermined spacing to be obtained between adjacent boards being fixed to substrates, and the tools are removed once permanent fixings are applied to the board. <IMAGE>
