Patent GB-2103871-A (GB)
Title: Laser apparatus
Inventor: SHELTON DAVID PETER
IPC: G02F1/37
Filed: 1982-06-23
Abstract: A harmonic frequency of a laser beam is amplified by generating a series of electric fields across the beam, successive fields being directed oppositely. The spacing between the fields is related to the speed of propagation so as to amplify a particular harmonic. Typically this will be the second harmonic so that the amplifier acts as a frequency doubler. The fields can be provided by an array 6 of electrode pairs positioned on opposite sides of the beam 2 with a voltage generator 8 connected across the sets in alternately opposite sequence. The electrode pairs can be contained in a pressure cell 5 having means for varying the pressure therein in order to control the propagation speed. <IMAGE>

Title: Band clamps
Inventor: BREWAEYS PAUL
IPC: A61M16/04
Filed: 1982-07-08
Abstract: An adjustable clamp e.g. for a tracheostomy tube, has a sleeve (20) of deformable material that is slidable along the tube. A collar (27) embraces the sleeve (20), one end of the collar having a central cut-away between two arms (31) and a lateral axle (33) on which is mounted a cam (34).

Patent GB-2108858-A (GB)
Title: Injection apparatus
Inventor: SCHWEISS PETER
IPC: B03D1/14
Filed: 1982-10-20
Abstract: The injector apparatus is of the kind having a constriction which lies, in the flow direction, immediately before a following adjoining mixing section, in which fibrous stock suspension is mixed with air for the purpose of subjecting the suspension to flotation in a flotation tank. The mixing pipe in which the mixing section is disposed has a radial diffusor at its outlet end, and, for a greater flow rate of air, additional air intake bores are disposed therein a short distance in the flow direction after the constriction. A favorable arrangement is achieved if the injector apparatus with the mixing pipe is arranged perpendicularly in a flotation tank, which may have the form of a reclining cylinder. In this case, the froth, like the cleaned suspension, is drawn off on one long side, i.e., a side which extends parallel to the cylinder axis; the extraction opening for the cleaned suspension being provided preferably immediately below the level of the suspension and/or the froth extraction arrangement.

Title: Double glazing units
Inventor: CHERTON YVAN
IPC: E06B3/67
Filed: 1983-08-05
Abstract: A double glazing units is manufactured by securing vitreous sheets 4, 5 in spaced parallel relationship and securing a plastics foil 3 between and spaced from the vitreous sheets 4, 5.

Patent GB-2154614-A (GB)
Title: Densified coatings by application of direct fluid pressure
Inventor: RICKINSON BERNARD ALAN
IPC: F16D69/04
Filed: 1985-02-14
Abstract: By applying a coating layer to a substrate in a manner that avoids significant surface-communicating subsurface porosity, for instance by suitably controlled flame-spraying or plasma-spraying, the coating may be densified and, if required, diffusion bonded to the substrate, by the application of heat and direct isostatic fluid pressure. Single and multiple coatings may be applied and densified and bonded by this method. The method is applicable to the coating of substrates to impart required surface properties and also to the repair or healing of substrates having surface defects, e.g., resulting from mechanical damage. The method enables the production of high-performance friction brake elements by providing the working surfaces of, e.g., a light alloy substrate with a densified wear-resistant surface of required frictional properties.
