Title: Hot air balloon burners
Inventor: COLEMAN JAMES DAVID
IPC: F23D11/44
Filed: 1989-11-08
Abstract: A balloon burner makes use of the Coanda effect.

Title: Electrolytic colouring of anodized aluminium
Inventor: PATEL PINAKIN
IPC: C25D11/12
Filed: 1990-11-05
Abstract: A process for providing a variety of light to medium colours of anodised aluminium or aluminium alloys comprises the steps of anodising an aluminium or aluminium alloy workpiece in an aqueous strong acid electrolyte solution by application of direct current to form on the workpiece a porous anodic oxide film having a thickness of at least about 3 microns; subjecting the resulting anodised workpiece to alternating current in an aqueous strong acid eg. sulphuric acid electrolyte solution comprising an organic carboxylic acid containing at least one reactive group bound to the carbon atom in the alpha-position which is a hydroxy, amino, keto or carboxyl group eg. glycolic acid; and electrolytically colouring the workpiece. In a preferred embodiment resulting in deepened colour tones, including those in the blue to blue-gray range, one or more currentless "waiting periods" are maintained at various stages of the process. In another embodiment, improved colour uniformity is obtained by subjecting the workpiece prior to electrolytic colouring to a direct current pre-treatment step. The resulting electrolytically coloured aluminium or aluminium alloy is particularly useful for architectural product.

Patent GB-2246432-A (GB)
Title: Testing filter media
Inventor: PALL DAVID BORIS
IPC: G01N33/49
Filed: 1991-08-07
Abstract: A fibrous filter medium is subjected to grafting of hydroxyethyl, hydroxyethyl methocrylate and carboxylic acid groups thereto, in order to present anionic groups in the fibre surfaces and thereby enhance its ability to remove leucocytes from blood plasma without depleting the platelets. The efficiency of the medium to do this is tested by passing an aqueous solution of cationic dye therethrough. The dye is initially adsorbed from the solution, but eventually the emerging liquid turns from colourless to coloured as the medium saturates. The quantity of solution passed before this happens gives a measure of the efficiency.

Title: A method of preventing the buildup of deposits of plastics material in a chokedand rifled barrel of an air,gas or spring gun.
Inventor: EARL HUGH EDWARD
IPC: F42B7/10
Filed: 1992-08-11
Abstract: A pellet for use in the method has a metal head portion (1) and plastics tail portion (2). Maximum diameter portions (21, 22) on the tail portion (2) ensure that the pellet has low frictional losses as it passes along the bore of the gun barrel. Because the gun barrel bore has a choke, i.e. it tapers at its muzzle end, some of the tail portion (2) will be turned into swarf by the choke and will become stuck in the rifling. The head portion (1) has a metal maximum diameter portion (11) in order to clear from the rifling in the choke any swarf left by the previous pellet, without generating unwanted frictional losses in the unchoked part of the bore by imparting spin to the pellet by projecting into the rifling. <IMAGE>

Title: Measuring the volume of void(s) in structures
Inventor: BRETTEN DAVID CHARLES
IPC: G01F17/00
Filed: 1993-04-23
Abstract: In a method of measuring the volume of void(s) within an artificial or natural structure, compressed gas is applied to the void(s) until a preset pressure is attained; the natural leakage rate from the void(s) is determined; a further leakage path with a known leakage rate may then be opened; the supply of gas to the void(s) is terminated and the time taken for the pressure in the void(s) to drop to a preset value, at a known leakage rate, is recorded; and that time is compared with prerecorded data to indicate the volume of the void(s). A method is also disclosed in which an elevated pressure is to be maintained in the void(s), and the elevated pressure constitutes the preset value.
Patent GB-2268420-A (GB)
Title: Liquid treatment apparatus
Inventor: THOMAS NEALE
IPC: F03D9/00
Filed: 1993-07-05
Abstract: Liquid treatment apparatus has a cylindrical tank (1) over which is co-axially mounted a VAWT (3) which drives aerator tubes (10, 13) through liquid in the tank. These tubes have apertures (15) on their trailing sides (14) and either project above the liquid surface, their upper ends being open, or are totally immersed and communicate via ducts to a common central passage which projects above that surface. As the tubes are traversed through the liquid, air is drawn into them and escapes as bubbles through the apertures. The tubes may be directly attached to the rotor (6), or they may be carried by subsidiary rotors (7), planetary to the main rotor (6). The drive from the VAWT (3) may use the liquid in the tank (1) as part of a fluid transmission, or there may be a mechanical slip device between VAWT and the tubes. <IMAGE>

Title: Laminated interconnect tape
Inventor: MCGEARY MICHAEL LAWRENCE
IPC: H01L23/495
Filed: 1993-12-17
Abstract: A flexible laminated interconnect tape is suitable for use as an electrical interconnecting medium between electronic components and between bonding pads of integrated circuit die and IC packaging bond pads. The tape may be used as a modification to existing TAB (tape automated bonding) tape technology, or as a substitute to wire bond technology. The flexible laminated tape comprises a plurality of conductor layers (40)(a - y) eg of Al, each separated from adjacent conductor layers by a polymeric insulating layer (42)(a - z). The tape offers improvement to bonding processes by simplification of the requirement to create compatible metallurgies at the bond sites. By using vacuum deposition techniques to form the electrical conductor a wider range of materials (and characteristics) is made available for electrical interconnect. Benefits may also follow in the high-frequency signal transmission between interconnected components by reducing "skin effect" attenuation; this laminated tape could be regarded as an evolution of Litzendraht Wire. <IMAGE>
