Filed: 1985-12-05
Abstract: A number of beams of radiation at optical and near-optical wave lengths are multiplexed or demultiplexed by an array 14 of, preferably, variable spatial action of the array may be periodicity, ie a chirped array. The supplemented by a refractive element, eg a lens. As described, a complex light beam, comprising light of different wavelengths and entering the array in the direction 16, is distributed to different foci 18,20,22,24,26 and conversely light beams from the different foci are comeimed into a complex light scan leaving the array in the direction 28. The array consists of radiation reflectors which may be in the form of strips of conducting or dielectric material applied to an optical wave guide. Alternatively the reflectors may be grooves in such a wave guide. In another construction each reflector is an arrangement of applied dots of material. The performance of the array may be altered by modifying the shape and/or size of the individual reflectors systematically along the array. <IMAGE>

Title: Misalignment detection
Inventor: FOTHERGILL IAN ROBERT
IPC: G01B11/26
Filed: 1986-09-29
Abstract: Incorrect orientation of a component (10) with respect to reference orientation is detected by directing a laser beam (22) along a reference path (22) towards, and along the optical axis of, a lens (26) mounted on the component so that the beam undergoes reflection at the front and rear faces of the lens to form two reflected beams. The reflected beams may be intercepted by a screen (24) to provide a visual indication of any divergence between the beams. In the presence of any misalignment (which may take the form of lateral offset and/or tilt), the reflected beams form non-concentric spots on the screen (24). <IMAGE>

Title: Fibre reinforced racquet frame
Inventor: MOTT JONATHAN CHRISTOPHER
IPC: A63B49/10
Filed: 1989-02-16
Abstract: A method of making a fibre-reinforced moulded racquet frame comprises weaving at least one layer of braided reinforcing fibres around an extruded polyethylene foam core member to form a fibre-reinforced core. The core is placed in a mould having a cavity shaped to define the frame, and a methacrylate based resin, which has a relatively low setting temperature and viscosity, is injected into the mould around the core. Because of its low viscosity, the resin readily impregnates the fibres of the core, and produces a racquet frame requiring little or no surface finishing.

Title: Filling open containers, e.g. big sacks
Inventor: THUEER HERMANN
IPC: B65B39/00
Filed: 1989-08-04
Abstract: Apparatus for filling large open sacks, for example, with a capacity of 500 kg, is equipped with a compaction worm disposed in a double-walled hollow cylinder (12).

As a result of a rotary and upward movement produced by means of a member (27) passing through a hollow shaft (26) and connected to annular part (21), part (21) can be moved to a closure position. Each closure part (20, 21) is provided with an equal number of radially extending support spokes (23) for flexibly deformable closure plates (22). The radially extending edges of each closure plate (22) are fixed on the supporting spokes (23) of the upper closure part (20) and the lower closure part (21). In the filling position, the closure plates (22) are vertical while in the closure position they are substantially horizontal and overlap in order to provide a tight seal. <IMAGE>

Title: Test control apparatus
Inventor: LARKIN DAVID
IPC: G06F11/34
Filed: 1990-12-28
Abstract: A test control apparatus 1 is disclosed having a control unit 3 with a data controller 4 and a functionally separate processing controller 5. The data controller is connected to test instruments 2 and to a user interface 6 for creation of all data files including files for captured test data, test specifications, test instructions or sample identification codes. Such data files are created independently of the processing controller and of the format of instrument data file. The processing controller uses a program library 9 to assist in processing data retrieved in data files via the data controller to generate test reports at output interfaces 7. Because data and processing operations are carried out separately, modification of the apparatus for use with different types of test or test instruments may be easily carried out. Further, access to data is relatively quick because the data controller stores data in separate active and historical databases 15, 17. Data are stored in a relational manner which ensures that reports tying together information relating to a particular product may be easily carried out. <IMAGE>
