Patent GB-2164490-A (GB)
Title: An electron gun assembly for colour CRT
Inventor: MORRELL ALBERT MAXWELL
IPC: H01J29/50
Filed: 1985-11-06
Abstract: The assembly (Fig. 3) has a trio of inline cathodes (21), a first grid (G1, 23) positioned adjacent the cathodes and a second grid (G2, 25) positioned between the first grid and a first focussing electrode (G3, 27). Each grid and electrode has a trio of inline apertures aligned with the cathodes. A common, assymmetric focussing lens is, in use, established between the first focussing electrode (G3) and a second focussing electrode (G4, 29). The lens has a maximum transverse dimension in a first direction parallel to the plane of the inline apertures greater than its maximum transverse dimension in a second orthogonal direction. In order that the cross-section of each electron beam has a greater dimension in the first direction than in the second direction at the beam- entrance of the lens, there is a slotted structure (Fig. 7, 68) associated with said first (23) grid interposing a rectangular slot (68) between each aperture (64) of the first grid and the aligned aperture of the second grid. The long dimension of the rectangle is in the second direction in the first grid (23). <IMAGE>

Title: Dry hose liquid fuel delivery system
Inventor: HEIDT JOHN
IPC: B67D7/38
Filed: 1986-05-20
Abstract: A meter measuring system fitted to a road tanker A for the transport and delivery of liquids with low viscosity stored at atmospheric pressure comprises a pump P, a gas extractor Pg, and a meter C with an empty hose reel Hr. The hose I is emptied automatically by utilising the gases vented from the gas extractor. The empty hose has means of which a part, at least, is located at the hose reel gun; said part can be an electrical switch. The switch, when operated, will activate a solenoid which controls a valve, said valve when operated permitting the supply of a fluid (preferably pressurised air) to a rotary actuator which, in turn, will cause angular movement of its output shaft such as will cause closure of the flow-regulating valve to whose stem the rotary actuator is connected. Either the road tanker or the gun may have the solenoid/rotary actuator/flow-regulating valve mounted thereon. <IMAGE>

Title: Dispensing container
Inventor: DRUMMOND DESMOND CHARLES
IPC: B65D1/32
Filed: 1986-06-16
Abstract: A dispensing container comprises two main portions 11, 15 hinged together and a bellows portion 22 extending from the hinge 21 between the main portions and providing communication between the two main portions. When the two main portions are pressed together to compress the bellows portion, the interior volume of the container decreases and contents can be forced out of an outlet 13 which may be an adjustable spraying nozzle 14. The two main portions and the bellows portion may be moulded, by injection or blow moulding, in one piece and the container may be shaped at 12 and 16 to be held between the fingers and thumb for ease of application of pressure to squeeze the container. A special design of bellows is preferred with central element of the bellows portion stopping short of the hinge for better compression of the bellows portion, (see Fig. 6).

Abstract: In a pressure control valve including a hollow body 4 containing two chambers 27,28 each communicating with a respective port 2,1, a valve member 21 is slidably mounted within the valve body 4 so as to be movable towards and away from a position at which it closes a chamber intercommunication orifice 3, and a spring 41 urges the valve member in the latter direction. Passage means 36 enables fluid pressure from one chamber to impinge against each of two opposite sides of the valve member 21, and the arrangement is such that the area of impingement at each side is substantially the same when the valve member 21 closes the orifice 3 but is different when the orifice is open. As shown the body 4 is formed to two telescoping parts 5,6. In a second embodiment the valve member is supported by a diaphragm (159, Fig. 3) held between body parts (143,144) and a non-return valve is provided at the inlet (101). In a third embodiment an O-ring (235, Figs. 4-6) carried by the valve member assists in initial opening by preventing rapid exhaust into chamber 27. <IMAGE>

Title: Removing debris from electrostatographic surfaces
Inventor: THOMPSON PHILIP ROGER
IPC: G03G21/10
Filed: 1987-05-06
Abstract: An electrostatographic copier has a transfer zone at which a toner image is transferred from a moving member, e.g. belt (3) to a copy sheet, and a cleaner blade (5) for removing residual toner from the belt after image transfer. A trap (25) is provided to collect paper fibres and other debris from the belt after the transfer zone and before reaching the blade (5).

Title: Sound level meter
Inventor: OGBORNE JOHN
IPC: G01H3/12
Filed: 1989-03-10
Abstract: A portable, battery operated sound level meter is intended for use by musicians, particularly string or wind players and singers, for the purpose of improving bow or breath control.

Title: Hose coupling
Inventor: CARRICK NEVILLE
IPC: F16L33/22
Filed: 1989-04-19
Abstract: A hose coupling comprising a sleeve 3 having a first part 4 an external diameter corresponding to the internal diameter of the side of hose 2 to be fitted, the sleeve 3 having at an opposite end a second part 6 with a smaller external diameter, the two diameters being joined by a conical surface portion forming a third part 7 of the sleeve, the said second part 6 carrying a screw threaded region 8 upon which an internally-threaded ferrule 9 is located, the arrangement being such that rotation of the ferrule 9 serves to move an internally-tapered ring 12 in a longitudinal direction such that the tapered surface of the ring 12 will exert a clamping action with respect to the sleeve third part 7 in order to compress an end portion of the hose 2. This gives a coupling which can be fitted without making an increase in the hose external diameter and it thus enables the hose to be stored easily on a hose reel. <IMAGE>

IPC: B65B55/02
Filed: 1990-01-08
Abstract: The machine includes a sterile tunnel 1, a tunnel discharge channel 5 which is provided a cup-retaining means 12, a lifting plunger 15, and a transfer mechanism 16, the lifting plunger 15 being raised to the limited extent required to dispose a cup in the discharge channel retaining means so that the discharge channel 5 will be closed by the cup until this cup is extracted from the discharge channel by the transfer mechanism (16) and a subsequent cup at the same time is lifted into the discharge channel by the lifting plunger. This enables the pressure of the sterile air in the sterile tunnel to be kept substantially uniform and at the same time eliminates or minimises the danger of the germs being introduced into the discharge channel (5) and/or the sterile tunnel (1) via the lifting plunger. The consumption of sterile air is also considerably reduced. …<IMAGE>…
