Title: A scaffolding module and method of erecting same
Inventor: PRESTON JOHN CLEMENT
IPC: E04G1/34
Filed: 1985-09-19
Abstract: Scaffolding module comprising one or more substantially planar frames (3, 15) to receive building materials; each frame (3, 15) is supported, in use, in a substantially horizontal position by four substantially parallel support members (2) and each frame (3, 15) and the support members (2) are pivotable relative to each other. Hence, the module (1) can be folded between a reduced volume storage configuration in which each frame (3, 15) lies alongside the support members (2) and an operational configuration in which each frame (3, 15) extends substantially perpendicularly to the support members (2). A method of erecting scaffolding using the described modules is also disclosed.

Patent WO-9100986-A1 (WO)
Title: Flow detection
Inventor: TASSICKER PHILIP G
IPC: G01P13/00
Filed: 1990-07-10
Abstract: A fluent material flow detector detecting a threshold flow rate rather than a quantitative value. Movement of a magnetic material (31) and a detector (33) sensitive to magnetic field changes determines whether flow is occurring. A threshold value determines whether a certain flow condition is deemed to be flow or not. Circuitry enables the flow detector to be used in a variety of process control applications.
Patent WO-9103682-A1 (WO)
Inventor: COWLING IAN ROLFE
IPC: E06B9/28
Filed: 1990-09-07
Abstract: There is provided illuminating apparatus including an illuminating channel (10) defined between an incident surface (11), an emergent surface (12), an upper surface (13) and a lower surface (14). The upper surface (13) includes end portions (15) which may be adhered to the lower end portions (16) of an adjacent illuminating channel. The portion of the upper surface (13) between the end portions (15) comprises a steeply inclined outer portion (17), a horizontal central portion (20) and a shallow inner inclined portion (21). Light entering the incident face (31) at a low angle of incidence is reflected by total internal reflection in turn from the lower outer surface (32) of a first cavity (33), the central portion of the upper surface (34) of a second cavity (35), and then the inner lower surface (36) of the first cavity (33) before emerging from the emergent face (37). Light entering the incident face (31) at a medium angle of incidence is refracted at the incident face to a lower angle of refraction such that most incident light is reflected from locations distributed along the upper surface (40) of the cavity (41). Light entering the incident face (31) at a high angle of incidence is refracted to a lower angle such that most incident light falls on the outer end of the upper surface (42) of the cavity (43), such that the light rays are deflected through an angle sufficient for them to emerge from the emergent face (37) diffused and approximately perpendicular to the latter.

Abstract: L'invention concerne un appareil mélangeur utilisé avec un récipient centré autour de l'axe longitudinal. Ledit mélangeur présente un corps lame formé le long de l'axe de tête central. Ledit corps lame présente une première extrémité, une seconde extrémité espacée de la première extrémité le long de l'axe de tête, et un passage s'étendant entre la première et la seconde extrémité. Ledit passage défile de la première extrémité vers la seconde extrémité. La surface extérieure du corps lame définit un diamètre de lame interne ID sur la seconde extrémité et un diamètre de lame externe OD sur la première extrémité. Le corps lame est positionné à l'intérieur du récipient et est coaxial à celui-ci. Un excentrique Scotch, relié de manière fonctionnelle au corps lame par une tige, fait bouger de manière longitudinale réciproque le corps lame sur une course S, pendant une durée T calculée pour chaque course. L'efficacité de mélange est améliorée, lorsque le mélangeur fonctionne grâce à un ensemble de paramètres fonctionnels définis par l'équation : 80 = 0.36 x OD2/ID2 x S/T = 550, lorsque OD, ID et S sont exprimés en pouces, et T est exprimé en minutes.

Abstract: SUBMERSIBLE VACUUM CLEANER                        ABSTRACT         The invention provides a self-contained cordless electric pool and spa vacuum cleaner which is easily maneuverable over both flat and highly contoured underwater surfaces.  A pump impeller, powered by an electric motor, is used to draw water through a compact filter cartridge.  The efficiency of the filter cartridge allows for the use of a small motor and small battery which, in turn, result in the small size of the vacuum cleaner.  All electrical components are enclosed in a watertight chamber so as to allow the entire cleaner to be submerged under water.

IPC: G01N33/48
Filed: 1989-11-29
Abstract: A device for separating mononuclear cells from blood includes a collection tube, a first layer of a liquid density gradient material placed in the tube, a second layer of a gel-like substance placed in the tube and situated above the first layer, a porous foam member placed in the tube and situated above and in contact with the second layer of gel-like substance, and a third layer of a Newtonian gel-like substance placed in the tube above the porous foam member.  The gel-like substance of the second layer has a lower specific gravity than that of the liquid density gradient material of the first layer so that it floats on top of the first layer.  The gel-like substance of the second layer becomes less viscous when heated such that it is absorbed by the porous foam member and forms a hydraulic barrier between the liquid density gradient material of the first layer and a blood sample placed in the collection tube.
