Title: Improvements in or relating to the manufacture of metal-faced frames
Inventor: JAMES ANTHONY
IPC: A47G1/06
Filed: 1982-11-16
Abstract: A method of manufacturing a rectangular metal-faced picture frame comprises forming from plastics material four elongate frame members 10 each having a longitudinal curved front face 17 formed with a longitudinal recess 22 along one edge thereof, inserting into the recess 22 one longitudinal edge 25 of a metal facing strip 24, pressing the part of the strip extending away from said edge into engagement with the curved face, securing the opposite longitudinal edge 26 of the metal strip to the frame member, mitreing the ends of the metal-faced members, and securing them together in rectangular configuration to form a frame, by securing angled corner elements 27 within grooves 16 in the rear surfaces of the frame members. <IMAGE>
Patent GB-2113122-A (GB)
Title: Centifugal separator
Inventor: MARTIN HENRY WOODS
IPC: F01M1/10
Filed: 1983-01-18
Abstract: A centrifugal separator for separating contaminants from contaminated oil has an outer casing (10, 11) and a rotor (20) within that casing mounted for rotation about a vertical axis. Oil under pressure enters the rotor at one end and at the other end exits through jets (78) into a chamber within the casing which is normally filled with air. As the jets of oil impinge upon the inner wall of the casing, a small amount of air becomes entrained in the oil and as the oil flows to a sump, the air is gradually removed from the interior of the casing. In order to prevent a build-up of oil within the casing, which could interfere with rotation of the rotor (20), air under pressure is supplied to the interior of the casing by means of a float-operated valve member (113) so that while the valve member is normally closed, any increase in the oil level will cause the float (124) to rise with that oil level and thereby open the valve (113) to allow additional air to enter into the interior of the casing.

Title: Underwater buoyancy apparatus venting control
Inventor: BUCKLE BRIAN LEONARD
IPC: B63C11/32
Filed: 1983-09-06
Abstract: For an underwater buoyancy apparatus there is provided a device for venting gas from an expansible gas chamber of the apparatus when the rate of ascent of the buoyancy apparatus exceeds a predetermined velocity. The device has means 24-47 for monitoring the rate of ascent and providing a control signal when the predetermined velocity is exceeded, and a valve 20 controlling the venting of gas from the chamber. The monitoring means has a velocity member 47 which, in the ascent attitude of the device, extends laterally of the direction of ascent and is supported for movement upwardly and downwardly, and is exposed at its upper face to the ambient fluid so that sufficiently rapid ascent causes it to be urged downwardly, against spring loading 44, to decrease pressure in a chamber 41, allowing a piston 38 to move under air pressure. This allows air flow to a chamber 9, producing venting valve movement. <IMAGE>

Title: Exhaust catalytic combustor
Inventor: BERRY MICHAEL GEORGE
IPC: F01N13/02
Filed: 1984-07-11
Abstract: An exhaust combustor is used to boost the waste exhaust gas of an engine to a pre-designed state enabling further use (eg in a heat exchanger or inert gas plant). Connected to the engine exhaust it has an outer shell 21, causing the waste gases to pass through a particulate filter 29 and flash arrestor 31 prior to being injected with fuel 32 and admixed in static mixer 33. Normal exhaust temperature (or burner 28 for rapid warm-up) initiates the oxidisation or combustion process within a highly selective catalyst 34 which utilizes precious metal to gain maximum combustion efficiency at a perferred operating range of 1100 - 1450 DEG C. Where required, air is supplied at 30 for combustion and 35 for increased mass to gain engineered thermal/mass balance. <IMAGE>

Title: Sheet presenter
Inventor: WAKE DAVID EDWARD
IPC: B65H31/30
Filed: 1985-02-21
Abstract: A sheet presenter for use in a cash dispenser, for example, comprises a sheet receiving container pivotally mounted at 8 to a housing for movement between a sheet receiving position (shown) and a present position. The container is biased towards the present position by a weight 11. A latch system is provided for holding the container in the sheet receiving position. A retainer flap (18) retains sheets in the container. Control means such as a microcomputer- controlled solenoid controls operation of the latch system and of the retainer flap (18). The arrangement is such that when a quantity of sheets 21 are present in the container, the control means releases the latch system and selectively controls actuation of the retainer flap (18) so that during clockwise pivotal movement of the container the sheets are either carried to the present position or dropped through a dump opening 23. Selective control of the flap 18 depends on detecting the number of sheets in the container. <IMAGE>

Abstract: A wheel alignment gauge for measuring the toe-in or toe-out alignment of a pair of wheels includes a pair of symmetrical rigid channel members, one supported on each wheel by rubber straps hooked in holes 8 and passing around each wheel. Each member is located such that projections (11, 12) contact the wheel rim to align a reference point pair 14, one of each member, both forward and rearward of the wheel. A measurement of the difference in separation between the forward pair and rearward pair of reference points may be made in selected units. The reference points (14) of a member are arranged to be substantially 57.3 measurement units apart, so that the difference measurement provides a direct reading of toe-in or toe-out in degrees, without recourse to geometrical calculation or angle measurement. <IMAGE>

Title: Improvements in or relating to discharge lamps
Inventor: ROY ASHUTOSH
IPC: H01J61/36
Filed: 1986-07-11
Abstract: A lead wire which comprises at least two parts 14, 15, at least one 15 of these parts being made of HRTD (high recrystallisation temperature doped) molybdenum, is provided for use in an electrode assembly in a fluorescent lamp. The molybdenum contains 200-1200 ppm of silicon, 50-500 ppm of potassium and 0-120 ppm of aluminium. End blackening is a problem with the prior art, but HRTD molybdenum is sufficiently refractory and has a sufficiently high melting point for very little end blackening to occur when the section of an electrode lead wire which supports the electrode 9 is made from it. It also has a higher thermal conductivity than materials previously used and is therefore able to conduct sufficient heat away from the electrode with a reduced size of wire. Manufacturing is made easier because its possible to have a smaller difference in diameter between various parts of the lead wire. <IMAGE>
