Patent GB-2151339-A (GB)
Title: Pressure relief valves
Inventor: GOUDIE ROBERT JOHN
IPC: F16K17/08
Filed: 1984-12-04
Abstract: A fluid pressure relief valve comprises a housing (1) provided with a pressure inlet (3) and a relief outlet (4), a chamber (6) in communication with the relief outlet (4), a valve member (5) for controlling flow between the inlet (3) and the chamber (6), the valve member (5) having a seating portion (9) adapted to close the inlet (3) and an area responsive to the pressure in the chamber (6), with resilient means (10) biassing the valve member (5) to close the inlet (3) against pressure applied to the inlet (3), the valve being so constructed and arranged that on initial opening of the valve pressure builds up in the chamber (6), producing a force to act on the valve member (5) in opposition to the force produced by the resilient means (10). The chamber (6) is in communication with the outlet (4) through passages (7, 8) in the valve member (5). These passages may provide the only communication between the chamber (6) and the outlet (4). Alternatively a further connection (14) is provided between the chamber (6) and the outlet (4), flow through which is controlled by the valve member (5) Fig. 2, (not shown). <IMAGE>

Abstract: A fluid control valve comprising means defining a flow path for fluid (16), a variable flow restrictor in said flow path comprising a wall member (5) bounding a portion of said flowpath, and having flow passages (19) therethrough, means (20) for at least substantially closing a portion of said wall member against fluid flow therethrough, means (6) for producing relative movement between said wall member and said closure means to vary the area of said wall member exposed for fluid flow therethrough, the size of the flow passages through said wall member being such that there is at least one inlet pressure at which the valve with at least a substantial portion of the wall member exposed for fluid flow will produce a pressure drop substantially equivalent to the inlet pressure. Preferably, said valve will produce said pressure drop at inlet pressure above 498 Pa (2 inches water gauge). In Figs. 1 and 2, a perforate tube 5 reciprocates in a conduit 16. In Fig. 4, a shutter 40 with an aperture 41 rotates within a partially perforated member 37. The valve is located in an inlet for treated air forming part of an air distribution terminal 12 of an air treatment system. <IMAGE>

Title: An acoustic emission load cell
Inventor: ANGUS JAMES PEARS
IPC: G01G3/12
Filed: 1988-07-30
Abstract: An acoustic emission load cell (10) comprises a sheet of e.g. carbon fibre composite (12) positioned between two sheets of rubber (16, 18) and a conductor rod (14) is formed integrally with the carbon fibre composite (12). The carbon fibre composite (12) is an acoustically noisy material in that applied mechanical deformations generate acoustic emissions, or stress waves, which propagate there-through. An acoustic emission transducer (20) is acoustically coupled to the conductor rod (14), and the transducer (20) detects any acoustic emissions and converts them into an electrical signal. A signal processor (22) processes the electrical signals to give an electrical output signal which is a measure of the load applied. The electrical output signal is supplied to a recorder (24) and/or a display (26). The acoustic emission load cell is suitable for use in monitoring the load applied to railway line tracks by locomotives or rolling stock. Other suitable acoustically noisy materials may be used for the load cell. <IMAGE>

Abstract: Cross-linked labelled antibody conjugates are described which have at least one non-disulphide interchain bridge. The bridge may be the residue of a homo- or hereofunctional cross-linking reagent, and is located away from the antigen binding domains of the antibody. The antibody conjugates have an enhanced binding capacity and in vivo have good blood clearance and, in the presence of a tumour high tumour: blood and tumour: bone ratios. The conjugates are of use in the diagnosis and therapy of e.g. tumours and may be prepared by reaction of a cross-linking reagent with an antibody.
