Title: Priming valve and priming circuit for impeller pumps
Inventor: TEBBY STEPHEN WALKER
IPC: F04D9/00
Filed: 1983-02-14
Abstract: Passageway 1 connects the outlet side of an impeller pump to the valve body 2 which is then connected via passageway 3 to an air evacuating device. Valve rod 4 carries valve disc 5 which is biassed open by spring 8 to provide an open passageway during the priming process when the transported fluid is air but which closes on completion of the priming process when the transported fluid is water or a liquid. Pump outlet pressure maintains the priming valve in the closed position until such time as the impeller pump either stops pumping or loses its prime. <IMAGE>

Title: Filter and Method for Obtaining Blood Plasma Samples
Inventor: VINCENT MONTY E
IPC: A61B10/02
Filed: 1984-03-12
Abstract: The filter is for use during hemodialysis and is of the cross-flow type having a blood flow chamber 45 through which the blood flows and a plasma chamber 46 separated from the blood flow chamber by a filter medium 32 which enables the passage of the plasma therethrough while blocking the passage of the red cells of the blood, the plasma chamber having a volume not exceeding about 2 milliliters. In the preferred use the plasma chamber is filled with saline solution except when a plasma sample is taken at which time the saline solution is first withdrawn and then the plasma sample is withdrawn through a sealable opening 38, after which the plasma chamber is again filled with saline solution whereupon plasma in the plasma chamber flows back through the filter medium into the blood flowing through the flow chamber. The filter and method enable accurate periodic analysis of the patient's blood plasma without any loss of red cells to the patient and with minimal loss of plasma. <IMAGE>

Title: Improved dump trailer
Inventor: BETTS NEIL ROBERT
IPC: B60P1/16
Filed: 1984-09-26
Abstract: A high discharge scow-back dump trailer is characterised by the feature that the scow chute embodies a flap 17 and there are rams 22 which, when operated, and with the trailer body 11 raised by rams 16 through at least part of its available arc of swing for discharge, will selectively open and close the flap 17 so that grain or other material carried by the trailer will be largely or wholly discharged through the chute opening created when the flap is opened. The flap comprises adjacent flap sections each opening and closing around the beams 14 which extend longitudinally of the trailer chute and the major floor tray of the body.

Title: Karman vortex flowmeters
Inventor: MIYOSHI NORIOMI
IPC: F02M69/48
Filed: 1985-02-05
Abstract: A vortex detector has an oscillatory plate 9 which can oscillate, in response to conveyed vortex pressure changes, pivotally about an axis along which extend torsional bands 10a, 10b, supporting the plate 9 in a frame 11 formed in unitary fashion with the plate 9 and torsional bands. Means are provided for tensioning the torsional bands and for damping their torsional movements. The fundamental oscillation frequency defined by the moment of inertia of the oscillatory plate 9 and the torsional spring constant of the bands 10a, 10b, is made substantially equal to the lowest vortex frequency to be measured, by appropriate selection of the length and width of the bands and the dimension of the oscillatory plate and other characteristics. Hence sensitivity at low flow velocities increases and excessively large displacement amplitudes prevented at high flow velocities. <IMAGE>

Title: Roll damping in a watercraft
Inventor: JONES CLIVE
IPC: B63B39/03
Filed: 1985-11-18
Abstract: A watercraft is provided in its hull (10) with a plurality of spaced apart transverse roll resistance ducts (12), each of which rises from each side of the hull towards the plane (13) of symmetry of the hull to form an air pocket chamber (18). A baffle plate (20) is positioned in each duct (12) in the plane (13) to restrict water flow, but permit air flow, between the duct halves on either side of the plane. The arrangement of the ducts (12) is such that water entering a duct from either side of the hull (10) under the action of a beam swell exerts a downward force on the rising base wall (16) of the relevant duct half and also displaces air in the chamber (18) from that duct half to the other duct half. The mentioned downward force, combined with the shift in the centre of buoyancy produced by the air displacement, creates a couple resisting roll of the hull with the swell. <IMAGE>

Title: Emergency escape breathing apparatus
Inventor: KUGLER SIMON
IPC: A62B7/00
Filed: 1986-04-17
Abstract: In emergency escape breathing apparatus air or other breathable gas is supplied to the interior of a hood 1 which envelopes the head of a wearer. A half mask 5 mounted near a visor part of the hood 1 engages the nose and mouth of the wearer so that the gases breathed by the wearer are inhaled from and exhaled to the interior of the half mask 5. Gases pass between the interior of the half mask 5 and the interior of the hood 1 during both inhalation and exhalation, but, when the pressure within the half mask rises during the latter part of the exhalation, an exhale valve 8 mounted within the half mask opens and allows the exhaled gases containing the major part of the carbon dioxide to be expelled into the surrounding atmosphere. Preferably the walls of the half mask 5 are formed of a porous material such as open cell foamed plastics material. <IMAGE>

Patent GB-2181643-A (GB)
Title: Aerated baths
Inventor: LEWIS ROBERT
IPC: A61H33/02
Filed: 1986-10-20
Abstract: Air is blown into a bath through inlet ports which are at the ends of air-supply tubes. A little hot water is fed into the air stream to compensate, at least partially, for heat-losses. The invention provides apparatus for preventing unpleasant fluctuations in the hot water supply to the air-supply tubes. The apparatus has a chamber (22) with an air inlet (5) and outlet fitments (1) attached to the air-supply tubes. The airflow rotates a rotor (17) provided with fan blades (21). Hot water entering the chamber through inlet holes (9), from a reservoir supplied through an inlet fitment (7), falls on the rotor and, thus being subjected to rotary forces, is propelled outwards and is distributed around the chamber. A mixture of air and drops of water passes from the chamber into the air-supply tubes. The rotor may be motor-driven, or it may be omitted, in which case the air is introduced tangentially into the chamber to subject the water to rotary forces. <IMAGE>
