Title: Photoelectrophoretic imaging system
IPC: G03G17/04
Filed: 1969-02-20
Abstract: Photo-electrophoretic imaging process comprises contacting the surface of a transparent electrode with a suspension of electrically photosensitive particles in an insulating liquid having immersed therein at least one coronode, and exposing the suspension through the electrode where the latter contacts the surface while moving the electrode past the coronode thus forming an image of the photosensitive particles on the electrode. The coronode(s) may be in the form of a needle, a knife edge or a wire. In a first embodiment, the transparent electrode is in the form of a rotatable drum inside of which are positioned a lamp and an original to be copied to effect exposure of the suspension, the lower part of the drum contacts a suspension containing 3 knife-edge coronodes the drum is rotated through the suspension so that there is formed thereon an image which is then transferred to a web, and the drum cleaned. In an alternative embodiment, the electrode is in the form of an endless belt to which is attached on its surface an original to be copied the belt and original are passed through 3 imaging stations each comprising a lamp, a colour filter, a suspension containing particles complementary to the colour of the filter, and a knife-edge coronode, so that there is formed on the belt a multi-colour image which is transferred to a web.

Title: Thin film metallization processes for microcircuits
IPC: H01L49/02
Filed: 1970-07-20
Abstract: Selective anodic oxidation is employed to pattern thin metallic films in the fabrication of printed circuit boards and integrated microcircuits to provide "inlaid" metallization geometry and thereby eliminate the need for selective etching of metal films.

Title: Apparatus for separation of waste material from a moulded article
IPC: B29C45/00
Filed: 1976-09-16
Abstract: A method of and apparatus for separating off waste material from a moulded article in the production of hollow articles of thermoplastics material by a blowing process in a multi-part mould involves pinching together regions of a partly-made article during closure of the mould parts around it and once a satisfactory weld seam has been created at the pinch regions then increasing the closure speed of the mould parts. Control of the mould closure speed may be effected by open loop control or by automatic control, and may be made dependent on time and/or on displacement of the mould parts. The increased final closure speed can with advantage be equal to the mould closure speed at which the mould parts are moved up to the beginning of the pinching process.
