Title: Preparation of transparent artwork - by exposure to actinic light and layer to layer removal of material to form mask
IPC: G03F1/00
Filed: 1976-07-12
Abstract: Transparent artwork is formed by taking a substrate transparent to actinic light and a masking layer translucent to actinic light is formed in the near surface portion of the substrate, and a predetermined topological relief pattern is made by local layer to layer removal of the material on the side of the masking layer, with concurrent measurement of the optical phase difference between light rays passing through the masking layer and transparent portions of the artwork until the geometrical relief of the pattern becomes deep enough to ensure an optical phase difference which is a multiple of 2 phi. Method may be used for preparing artworks employed in photolithography for making thin film and integrated microcircuits. Method ensures high stability of photo lithography using transparent artworks, broadens the range of operating exposures, renders the optical density of masking coatings less critical, and provides for reproducibility of the optical characteristics of artworks.

Title: Generating compound plasma configuration - using pressure chamber for isolation and compression of plasma
IPC: H05H1/02
Filed: 1976-08-13
Abstract: The plasma configuration includes a central toroidal plasma with electrical currents surrounded by a generally ellipsoidal mantle of ionised particles or electrically conducting matter. The methods of forming this compound plasma configuration include the steps of forming a helical ionised path in a gaseous medium and simultaneously discharging a high potential through the ionised path. A helical or heliform current is produced which collapses on itself to produce a toroidal current. An alternative method is to generate a toroidal plasmid, supply magnetic energy to the plasmid, and apply fluid pressure external to the plasmid. The apparatus includes a pressure chamber where the compound plasma configuration can be isolated or compressed.

Used esp. for coating surfaces of concrete, asbestos-cement, plaster, stone, terracotta, marble etc. Also for coating metal (steel) substrates. Smooth adherent, thin coatings may be formed.

Title: Repairing ingot moulds - by the use of a plate welded across crack, with threaded holes on each side of crack providing anchorage
IPC: B23P6/04
Filed: 1976-11-04
Abstract: The repair of ingot moulds involves the formation of two rows of threaded holes in the exterior wall of the mould, each row being formed on opposite sides of a crack or fissure in the mould wall and effectively coinciding with holes formed in a thick plate. Anchoring devices are screw fitted into the threaded holes, the lengths of the anchoring devices being such that their exterior parts or heads project from the surface of the mould and are located in the holes in the plate which is applied against the outer surface of the mould, the holes in the plate being large enough hot only to accommodate the heads but also form a residual cavity. Each cavity is then filled with a metallic material which solidifies to join the plate and the upper part or head of each anchoring device. The repair is quick and relatively simple enabling the mould life to be substantially increased. The repair is also relatively low in cost and its quality is such that it can be used for low capacity ingots with increased repair life.

Title: Electric cable connector with cable gripper - has two shank socket portion whose shanks overlap laterally for cutting into cable insulation
IPC: H01R4/24
Filed: 1977-03-15
Abstract: The telephone cable connector is of solderless type and has a clamp, gripping the conductor, with a socket with two elongated shanks. These are spaced and have two sides in intersecting relationship. The intersections form sufficiently sharp and rigid edges for cutting through the conductor insulation.

Title: Procede et dispositif pour effectuer l'inversion d'une image
IPC: G03G15/10
Filed: 1977-06-27
Abstract: L'invention concerne un procédé et un dispositif pour effectuer l'inversion d'une image. Un révélateur liquide 30 est introduit dans une chambre 22 contenant une surface photo-conductrice 16 portant une image latente d'une pellicule electrophotographique 10, et une plaque métallique 20 parallèle et espacée définissant les deux limites de la chambre. Une forte polarisation continue 26 est appliquée à travers la chambre 22, dont la valeur et la polarité sont suffisantes pour élever les zones du fond de l'image latente à un fort potentiel de charge et réduire les zones très chargées restantes de l'image latente à zéro. La polarité des zones chargées de façon intermédiaire est inversée mais la grandeur relative de leur charge est maintenue. Le révélateur 30 utilisé a une polarité opposée à celle de la polarisation. Quand la révélation est terminée, la polarité est inversée pour entraîner les particules flottant dans le révélateur vers la plaque. L'image obtenue est l'inverse de l'image latente << originale >>. L'invention s'applique notamment à l'électrophotographie.
