Title: Beer pump simulating hand pump
Inventor: REDFORD ALAN HARRY
IPC: B67D1/12
Filed: 1991-03-18
Abstract: A pump (1) is provided which simulates old fashion hand beer pumps creating the impression that beer is being drawn by hand. The resistive force is provided by a sealed cylinder (11) containing a piston (10) so that the force, against which a drawing stroke is made, is provided by a mixture of water and glycerine flowing past a narrow annulus of the piston (10) in the cylinder (11). Because water and the glycerine is relatively viscous the tolerances on the piston (10) and cylinder (11) are relaxed. A valve arrangement is provided in the piston (10) so as to permit the glycerine and water to flow relatively easily past the piston (10) on the return stroke. The cylinder (11) is supported on a resiliently deformable support (40), which is a cylindrical spring, such that on activation the complete arrangement is displaced so as to activate by bolt (14A) a valve (14) external to the cylinder (11) through which valve (14) beer flows; e.g. under carbon dioxide pressure. <IMAGE>

Abstract: An absorbent article (1), such as a napkin or pad for catamenial or incontinence purposes includes a liquid permeable sheet, a liquid impermeable antileakage sheet (3), and a liquid retentive absorbent element interposed therebetween, to form a generally elongate absorbent body. A pair of fixing elements (5) normally integral with the sheets, extend laterally outwardly from each side of the body, each of the fixing elements carrying, at least on its back surface, an adhesive area (6). The fixing elements (5) are movable between a first position in which they are extended laterally from the body and a second position in which they are folded back against the body and in which the adhesive areas (6) are adhered to a portion of the back surface of the body (which may itself be adhesive or non-adhesive). The nature of the portion and of the adhesive area is such that a backing release paper is not required. Second elongate adhesive areas may also be provided on the body. In use, the back surface of the article is applied to the inside of the crotch portion of a pair of briefs and the fixing elements are folded around the edges of the briefs and fastened to the outside surface by means of the adhesive areas (6). <IMAGE>

Title: Pig parlour coaxial fans mix fresh and recirculated air
Inventor: O'GORMAN PATRICK JOSEPH
IPC: F24F7/02
Filed: 1991-10-22
Abstract: An environment control system for a pig parlour (1) is described. The control system is to achieve strictly controlled uniform ventilation temperature distribution for weaned pigs. An external air inlet fan 8 is mounted co-axially with and above a recirculation fan 9 so that external and recirculated air streams impinge on each other, mix and spread out in a diffused manner transversely in radial directions from the fans. The mixed air is heated by a heater 10 required and is drawn down into the parlour by the action of the recirculation fan. A baffle plate 11 helps to assist in mixing of the air. The recirculation fan 9 is controlled accorded to external air temperature so that it reaches a maximum output for relatively low external temperatures for maximum mixing when cold air is being drawn in and minimum mixing when warm air is being drawn in. <IMAGE>

Title: Flame monitoring apparatus and method
Inventor: GLASSBY BRIAN
IPC: F23N5/08
Filed: 1991-11-12
Abstract: An apparatus and method are provided for discriminating between flames from different fuel sources. Such an apparatus and method may be used in multiburner installations to discriminate between flames from oil and flames from pulverised fuel. In the apparatus and method, a characteristic of the variation of the amplitude of flicker of radiation from the system with flicker frequency is detected. Although there is no particular frequency peculiar to one source of fuel, by which flames from that source of fuel can be identified, it is possible to make use of the different spectra of flicker frequencies produced in different burner operating conditions to discriminate between flames from different sources of fuel. <IMAGE>

Title: Pressure acturated and fired well perforating apparatus
Inventor: RICLES THOMAS DANIEL
IPC: E21B43/1185
Filed: 1992-02-06
Abstract: A firing apparatus for use with a tubing-conveyed perforating apparatus is disclosed. Wellbore pressure in a chamber 51 applies an upward force to a first piston 7 connected by a shearable coupling 10 to a firing piston 11. At a predetermined pressure the coupling 10 shears, allowing the first piston 7 to move upward. The first piston moves upward until the end of its integral rod 41 clears seals 21. This allows the pressure in chamber 51 to act on the firing piston 11 which is forced downward by the pressure, firing the perforating apparatus. <IMAGE>

Title: Coated bricks and the like.
Inventor: JONES DAVID WILLIAM
IPC: B05D5/06
Filed: 1992-07-03
Abstract: In manufacturing bricks or the like (particularly concrete bricks), one or more areas of a face of each brick are sprayed (by nozzles 22-24) with a pigmented composition and then that face of each brick is sprayed (by nozzles 32) with a second composition which contains no (or substantially less) pigment. The first spray forms dark marks over the areas sprayed and the second spray causes the boundaries of these marks to diffuse.

Title: A check valve assembly
Inventor: MARSHALL PAUL STEPHEN
IPC: F16K15/06
Filed: 1992-10-15
Abstract: A check valve assembly comprises a two-part housing (21, 22) in which are located two non-return valve inserts (2, 3) which are disposed in series along the axis of the housing. Each of the valve inserts (2, 3) comprises a fixed unit (8, 9, 10) which abuts a portion of the housing (1) and an axially displaceable member (6) which is spring-biassed to engage a valve seat (11) formed by a portion (10) of the fixed unit (8, 9, 10). The valve inserts (2, 3) are spaced from one another and retained in position within the housing by means of an annular spacer (4) which abuts at least one of the fixed units (8, 9, 10) of the two valve inserts (2, 3) in opposition to its abutment of the housing. Preferably, the spacer (4) can slide axially with respect to the housing so that when liquid is flowing through the valve, pressure on the spacer (4) forces it to slide into contact with the fixed unit of the downstream valve insert (3) in opposition to its abutment of the housing. Alternatively the spacer (4) is resilient and abuts the fixed units of both valve inserts (2, 3) in opposition to their abutment of the housing. <IMAGE>

Title: Strip casting
Inventor: FOLDER WILLIAM JOHN
IPC: B22D11/06
Filed: 1992-10-23
Abstract: In a method for casting metal strip in which molten metal is introduced into the nip of a pair of parallel casting rollers 16 via a tundish (18) and metal delivery nozzle (19) to produce a solidified strip, a clean head end of the strip (20) is formed by temporarily increasing the spring of the casting rollers to form a transverse bulge (103) across the width of the strip comprising a pocket of molten metal between two solidified metal shells (105) which defines a line of weakness across the width of the strip. The strip separates at the line of weakness under the weight of the leading strip portion 20a to form a clean head end for the following strip which can then be taken directly to a coiler. <IMAGE>

Title: Device for monitoring the surrounding space in real time for detecting and tracking possible enemy missiles
Inventor: COHEN JEAN-PIERRE DAVID
IPC: G06T5/00
Filed: 1990-11-30
Abstract: A device is disclosed for analyzing the surrounding space portion and for delivering periodically, at a sufficiently rapid rate, an image thereof in the form of a plurality of pixels. An extraction circuit (2) extracts, from said pixels, those which satisfy a first criterion usually satisfied by any pixel representative of a possible enemy missile, and delivers to a processing means (3) information relative to pixels of the environment of each of said extracted pixels. The processing circuit (3) processes the pixels thus extracted and their respective environment so as to determine whether they satisfy additional criteria usually satisfied by any pixel and its environment, represntative of a possible enemy missile, for deciding which extracted pixels are representative of an enemy missile. The extraction circuit comprises (Fig 6 not shown) a sequentially accessed image memory into different locations of which a plurality of values (intensity, contrast etc) are written due to their different times of arrival at the store as a result of processing delays, and a transfer circuit which reads out those values via a buffer location when transfer to the processor means is required.
