Title: Wrapping paper for smokeable articles
Inventor: PANGRITZ DR DIRK
IPC: A24D1/02
Filed: 1983-03-18
Abstract: Aluminium oxide fibers are integrated into the fiber structure of a wrapping paper for smokeable articles, more particularly a cigarette paper, so as to obtain a highly uniform fiber structure and hence improved mechanical properties and flow mechanics and, in conjunction therewith, better burning properties. In addition, the catalytic effect of the aluminium oxide in the burning zones influences combustion.
Patent GB-2137083-A (GB)
Title: Builders' trestle and fastening arrangement therefor
Inventor: DALLOW ARTHUR JOHN
IPC: E04G1/32
Filed: 1983-03-28
Abstract: A builders' trestle has a frame supported by legs. Each leg has a vertical portion (1) and the frame has uprights each capable of being in telescopic engagement with a respective portion (1). One of the vertical portion (1) and upright is provided with a slot (3) inclined with respect to the elongate axis, and the other of the vertical portion (1) and upright is provided with a hole which is to be aligned with the slot (3), whereby a fastening member, like a pin, may be inserted into the slot (3) and the hole such that relative axial movement between the frame and legs causes the fastening member to be forced against an inclined edge region defining part of the slot (3) and thus causes the frame to be tightly secured to the legs. Not only does the arrangement of the pin and slot (3) and hole provide a secure fastening, but it obviates the need for a separate fastening system such as a screw bolt which is an additional expense and can damage one of the members. <IMAGE>

Patent GB-2144520-A (GB)
Title: Flow limiting valve
Inventor: JACKSON ALAN DAVID
IPC: F15B13/04
Filed: 1983-08-06
Abstract: In a valve 10, a vent passage 36 in a valve spool 30 immediately downstream of a fluid jet 52 passing across the spool 30 in a metering mode connects to one of the servo chambers 34 which positions the spool 30. The effect of the exiting fluid jet 52 draws some fluid from the vent passage 36 thereby dropping the pressure level in that servo chamber 34 sufficiently to offset certain dynamic forces on the spool 30 and balance the spring forces on the spool 30 with these forces regardless of the flow rate through the valve 10. The valve supplies fluid from a pump 12 to a motor 16 which is driven at a constant speed determined by the size of a restriction 18 irrespective of the other loads 14 on the pump. <IMAGE>

Title: Reaction gas production
Inventor: LANGLITZ KARLHEINZ
IPC: B01J8/02
Filed: 1984-09-13
Abstract: Apparatus for the production of reaction gases, in particular of CO and H2, consists of a vessel which is at least partially filled with a catalyst, for example, of molten pig iron. The gases can be produced in principle from coal and oxygen by providing feed pipes for coal and oxygen as well as other active and reactive substances, such as hydrocarbons. The vessel (1) consists of a vessel bottom (2) which is lined with resistant material (6) and receives the catalyst (3), a cooled metallic top (5), an annular gasket (7) being provided between top (5) and bottom (2) and a gas outlet pipe (8) being connected to the metallic vessel top (5). This is a departure from reaction vessels which are uneconomical to operate, such as steel converters with a 100% lining. As a result, the gas production process become economical from the point of view of construction costs and, in so doing, avoids technical drawbacks such as the high weight and inertia. <IMAGE>

IPC: C08G73/10
Filed: 1986-02-27
Abstract: A 3',3'4',4'- or 2,3,3',4'-biphenyltetracarboxylic acid dianhydride is reacted at not above 80 DEG C in an amide-type organic polar solvent with at least one aromatic diamine having 1,2,3 or 4 phenyl groups in its chain and an -NH2 group on each terminal phenyl at the m-position. The resultant viscous solution of polyamide acid is formed to desired shape, e.g. by casting on a flat plate to form a film, and is heated to up to 150 DEG C to remove some solvent and is imidized by further heating to 350 DEG C or by immersion in a benzene solution of pyridine and acetic anhydride. Preferred solvents boil at 170 DEG C or less, e.g. dimethylacetamide and/or dimethylformamide. The resultant shaped polyimide article has bisphenylimide-aromatic recurring units, and has good colorless transparency without yellow or brown color. It is useful as an oriented film in a liquid crystal display or as a plastics lens.
