Title: Stress-grading timber
IPC: G01N3/20
Filed: 1980-02-01
Abstract: A method of stress-grading timber involves continuously moving a length of timber and stressing the moving length by applying a transverse load thereto. The length is supported by two supports between which the load is applied and the load causes a deflection of the timber length. The load and/or deflection are measured and the moving length is stressed differently by thereafter applying a different load to the timber length at the same position while supported in the same fashion to obtain a different deflection. The different load and/or deflection are measured and the original load and original deflection are related to the different load and different deflection to grade the timber. <IMAGE>

Title: Solvent etc. resistant surface modified containers
IPC: C08J7/04
Filed: 1980-12-15
Abstract: The present application relates to enclosure members e.g. bottles consisting essentially of solid, non- aromatic polymers that have a linear carbon to carbon backbone structure and having a plurality of free hydrogen atoms attached to the carbon atoms with a permeability to wet solvents and fuels of less than 1/7, optionally less than 1/40 of the permeability of untreated enclosure members having a thickness of 1 mm. Said low permeability is brought about by first sulphonating at least the inner surface with sulphur trioxide, washing with water and then treating with an aqueous solution containing ferrous sulphate and phenanthroline both in a concentration of at least 0.05 wt% at 20 DEG C. An iron/phenanthroline complex is formed on the surface, associated with the sulphonate groups.

Title: Piezo-electric ceramic couplers
Inventor: SCOTT KENNETH CLIVE
IPC: H01L41/257
Filed: 1982-01-14
Abstract: Piezo-electric ceramic couplers are manufactured by a method including screen or otherwise selectively printing or plating spaced-apart electrodes (2, 3, 4, 5) on opposite faces of an unpolarised piezo-electric ceramic body (1) and bonding them thereto. The electrodes are aligned in pairs (2, 3 and 4, 5). The body is heated to near its Curie temperature, a polarising voltage is applied between the electrodes of a pair and then the body is allowed to cool to well below its Curie temperature whilst still applying a polarising voltage between the electrodes of each pair. Thus the body is polarised only under the electrodes and the region (6) between the electrodes is of relatively high resistivity and is unpolarised. This enables small dimensions but relatively high dielectric strengths to be achieved between the electrode pairs. <IMAGE>

Title: Removal of spoil from mines
Inventor: ROSS JOHN STERRY HAWLEY
IPC: E21F13/04
Filed: 1982-03-09
Abstract: A water-filled installation for the removal of spoil from mines comprises an upflow pipe 2. Vessels containing spoil and air rise up the upflow pipe under their buoyancy.

Title: Device for fixing heat-exchanger plates to their carrying pipes
Inventor: BODAI IMRE
IPC: B21D53/08
Filed: 1983-09-26
Abstract: The device according to the invention fixes heat-exchanger fins (2) onto carrying pipes (1) without using any binding material in such a manner that the material of the flange of the heat-exchanger fin is fixed onto the carrying pipe by applying a proper pressure. The pressure to the flange is applied by means of a slit bush (3), whose external surface is cone-shaped and by means of a surrounding sleeve (4) whose internal surface is cone-shaped. The sleeve (4) is connected to a device for sliding the sleeve axially over the bush (3). Because of the conical shapes, the axial sliding of the sleeve (4) over the brush (3) causes the latter to constrict, thereby pressing the flange of fin (2) against the pipe (1). By applying properly selected compressive forces, the material of the flange is deformed on the carrying pipe (1), thereby establishing a bond between the flange and the pipe similar to a metallic bond. <IMAGE>
