Patent GB-2141989-A (GB)
Title: Pneumatic coneying of webs
Inventor: VITS HILMAR
IPC: C22F1/04
Filed: 1984-05-25
Abstract: The invention relates to a device for moving webs, in particular for the heat treatment of aluminium strip. In this device, the web is supported and conveyed by air cushion nozzles 5-12 which are assembled in pairs above and below the plane of the web and are mutually offset in the conveying direction. In each nozzle, the blowing air jets point towards one another asymmetrically and the nozzles in the pairs are mirror images of each other in such a way that the blowing air retained between them as an air cushion can flow out only over the outer nozzle edges of one pair. Due to this arrangement and design of the suspending nozzles, an essentially trapezoidal line of the web results, which has a stabilising effect due to its small radii or curvature at the corners of the trapezium. Due to the blowing air flowing out over the outer edges the relatively large area of the web of material between two pairs of nozzles is swept by the blowing air and is therefore adequately treated. <IMAGE>

Title: Process of treating wastewater containing biologically oxidisable material
Inventor: FUGGLE ROGER WILLIAM
IPC: C02F3/30
Filed: 1984-07-06
Abstract: A process for treating wastewater containing biologically oxidisable material comprises the steps of contacting and mixing the wastewater with bacterial active sludge in a well-mixed, unoxygenated contact zone. Then allowing the resultant mixture to separate in a settling zone (13) downstream of the contact zone into a sludge containing biologically oxidisable material adsorbed and absorbed by bacterial material in the bacterial active sludge, and a clarified effluent. The clarified effluent is discharged from the settling zone and the sludge is withdrawn from the settling zone to a stabilising zone (16). The withdrawn sludge is contacted with oxygen-containing gas in the stabilisation zone which allows the adsorbed and absorbed material to be oxidised biologically to form the bacterial active sludge which is passed to the contact zone. <IMAGE>

A region may be formed on the surface of the semi-insulating semiconductor between the third and first regions for suppressing the injection of carriers. The third region may be made from an epitaxial layer of opposite conductivity type formed on the semiconductor. <IMAGE>

Title: Combined thermal analysis and X-ray diffractometry
Inventor: FAWCETT TIMOTHY G
IPC: G01N23/207
Filed: 1985-02-25
Abstract: Scientific apparatus and a method are described for observing simultaneously both structural and thermodynamic properties of materials. An X-ray diffractometer and a thermal analyzer are mounted to cooperate and coact on the same sample and to complete a meaningful analysis in a very few minutes. The diffractometer is equipped with a rapid position-sensitive detector 38 connected to a multichannel analyzer to record and display X-ray diffraction data from the sample over an angle of 20 DEG  (two theta) or more. The thermal analyzer is preferably a differential scanning calorimeter. By correlating X-ray diffraction and thermal data taken simultaneously while the sample is passing through a range of temperatures and/or environments, structural changes corresponding to thermal events can be identified and elucidated. <IMAGE>

Title: Variable phase shift circuit
Inventor: FARR ADRIAN NIGEL
IPC: H03H11/20
Filed: 1990-03-10
Abstract: A variable phase shifter comprises a first inductor L1 arranged in series between input and output terminals, a series pair of capacitances D1, D2 arranged in parallel with the first inductor, and a second inductance L2 connected between the junction of the capacitances and other terminals of the input and the output. Alternatively capacitors D3, D4 may replace the inductors, and inductors L3, L4 may replace the capacitors to give the arrangement of figure 5. The reactance of the capacitances, which may be varactor diodes, can be regulated by the voltage applied at point 5, and this varies the phase shift between the input and the output terminals. The transmissive amplitude of the circuit remains substantially constant over a range of frequencies while the phase response varies. The varactor diodes and inductances, except choke C, are interchangable. The circuit is of use in a SAW oscillator, and for steering arrays in radar applications. <IMAGE>
