Abstract: The invention provides an improved test cell for detecting the presence of an analyte in a liquid sample. The device has an elongate casing (10) defining a liquid sample inlet, a reservoir volume a test volume and a window (16) through the casing at the test volume. Disposed within the cell is a sample absorbent, a novel biphasic substrate and a reservoir, together capable of transporting an aqueous solution within the casing along a flow path extending from the sample inlet through the test volume and into the reservoir volume. The invention further comprises a method for detecting the presence of an analyte in a liquid sample using the device and a biphasic chromatographic material for carrying out the method. The release medium is e.g. absorbent paper and holds a band of e.g. antibody-metal sol, and a band of e.g. antibody-biotin which bind to first and second epitopes respectively of the analyte. The capture site is e.g. nitrocellulose or nylon, holding an immobilized capture component, e.g. streptavidin. A control site may be present. The release medium and capture site are joined by overlapping to form the chromatographic substrate.

Title: Remotely locating a blockage in a pipeline for transporting hydrocarbon fluids
Inventor: SRINIVASAN JAGANNATHAN
IPC: F17D3/00
Filed: 2020-01-03
Abstract: Dynamic pressure wave propagation can be used in pipelines to provide information about the available, unobstructed diameter and any partial or complete blockages in the pipeline. Certain aspects and features can be used to locate a pipeline inspection gauge (pig) that may be deployed in the pipeline, since in terms of a pressure profile, the pig is no different than any other type of pipeline blockage. Regular pulsing of the pipeline with a pressure wave can further be used to track a blockage over time. A valve or any other suitable device such as an air gun can be used to generate the pressure wave. A time series analysis can be carried out to determine and track the location of the blockage.

IPC: H01L21/00
Abstract: 894,672. Semi-conductor devices. PHILIPS ELECTRICAL INDUSTRIES Ltd. June 27, 1958, No. 20704/58. Drawings to Specification. Class 37. A wire, at least the envelope of which is aluminium, and which is coated with a layer of oxide of sufficient thickness to enable fusion of the aluminium to take place without breakage of the oxide layer, is fused to a semi-conductor material. The oxide layer should have a thickness of from 3 to 40 microns and the semiconductor material and the material inside the aluminium envelope of the wire may be germanium or silicon, and tin may be used to connect the semi-conductor device to a base-plate. The device may be a diode or a transistor and in one embodiment (Fig. 3, not shown) it may be sealed inside an evacuated casing. A device according to the invention may be constructed by degreasing an aluminium wire by washing in caustic soda solution, nitric acid and then water and then oxidizing the surface either by dipping in a solution of H3PO3, CrO3, NH4HF2, and (NH4)2HPO3 in water or by subjecting the wire to anodic treatment at 60 volts D.C. in a solution of oxalic acid in water. The end of the wire may then be cut and polished and held in contact with a silicon body by means of a graphite jig (Fig. 2, not shown), while the whole device is heated in an oven to cause fusion to occur. Copper wire or cable may then be spotwelded to the aluminium wire at a point some distance away from the semi-conductive body.

Title: Control system feeding predetermined amt. of power - to thermoplastic tube sections weldable by the Joule effect
IPC: G05F1/66
Filed: 1977-04-14
Abstract: Electrical control system for supplying a predetermined amount of power to parts of thermoplastic conduits weldable by the Joule effect, stabilises by normal methods, the welding power, or the actual value indicated quadratically as J or U, of the welding current J or of th welding tension U. This may be effected by a regulator controlled by dephasing, at least approximately to a prescribed value, and the residual discrepancy in the value at any moment is compensated by the duration of welding so that the integral always gives, at least approximately, the value established for the joint in question. Method avoids the expense entailed in providing a highly accurate means of regulating the power supply with effective security against the possibility of errors. The objective of automatic control is achieved satisfactorily without more than normal commercial precision being called for from the different part-control circuits.

Filed: 1979-12-21
Abstract: In a plough of the kind which comprises a mobile frame (1, 2) and at least one plough member (15A) that will wholly or partly invert a furrow slice when the plough is in operation, said furrow slice is cut loose by a V-shaped blade (18) located at the front of the frame (1, 2) with respect to the intended direction of operative travel (A) of the plough and is both compressed, and deflected laterally towards one side wall (2) of the frame (1, 2) by a plurality of rotary lateral displacing members (4, 5, 6, 7, 8) that are in the form of rollers arranged in a row that is inclined to said direction of travel (A), the members/rollers (4, 5, 6, 7, 8) being of progressively increasing size considered rearwardly of the direction of travel (A). The lateral displacing members/rollers (4, 5, 6, 7, 8) co-operate with a soil guide member (15) at the rear of the plough in turning the cut furrow slice about an axis which extends in the direction of operative travel (A) to enable said furrow slice to be deposited substantially completely back into the furrow from which it was originally cut in a substantially completely inverted condition as compared with its original position. In a modification, the number of lateral displacing members/rollers is reduced and the guide member (15) in the form of a fixed plate is replaced by a power-driven rotary soil guide member of annular formation, the inverted furrow slice being delivered back into the furrow from which it was cut through the interior of said annular guide member.
