Title: Pull through element for pipes - consists of two ring gauges to measure alignment direction and twist
Inventor: REUSCH RUDOLF
IPC: G01B11/00
Filed: 1973-10-18
Abstract: The ring gauges are mounted at a distance from each other on a cylindrical sleeve, and are radially slotted. A cone is provided at each end of the sleeve for the gaude dia. adjustment. A collimator fills the space inside the sleeve. After each movement step optical marks on the collimator front and rear ends are made coincide by an optical point outside the tube. The ring gauges are connected with each other and with a traction cable, so that the cable traction reduces their dia. and makes possible their passage through the tube. When the cable is slack, the gauge rings press on the tube inner wall. Each gauge ring forms a unit together with its expanding sleeve and a closed annular strip. The two strips are connected by two pairs of straps hinged on a semiconductor bow to which the cable is attached.

Title: Coke oven charging gases extraction - by attacking telescopic section tube to gas offtake pipe after cover removal
Inventor: HOELTER HEINZ
IPC: C10B27/04
Filed: 1974-10-17
Abstract: The coal charging car for coke ovens of the horizontal chamber type is fitted with 4-6 pipes for each charging hole. The suction pipes are not attached directly to the charging holes but a telescopic pipe is connected to the gas ascension pipe of the oven from which a cover has been removed. The exhausted gases are passed to a combustion chamber and a water spray system. This eliminates the extraction of coal and coal dust from the charging holes which led to considerable coal losses. The new system is less complicated and saves the costly charging hole seals. It prevents contamination of the header by coal dust, if the gases are extracted through the collecting main.

Title: Image reproduction - by the use of laser beam on a polymeric material
Inventor: DUNKLEY ROWLAND ARTHUR GEORGE
IPC: G03F7/00
Filed: 1975-02-20
Abstract: Production of an image for use in a printing process by the known technique of scanning a film material, particularly a plastic film, with a laser beam, which is modulated in accordance with an electric signal derived by scanning an image to be reproduced, the plastic material and the output of the laser beam being such that an illustration of the image to be reproduced, is formed on the surface of the plastic film by the heat of the laser beam, but incorporating the novel feature whereby the surface of the film is treated with a material which only adheres to the laser-heated parts of the surface, and thereby makes the optical density of the heated parts of the film differ from the density of the unheated parts. The process is non-photographic and makes a dark room superfluous for introducing the film into the reproducing apparatus and for its subsequent development.
