Abstract: A line scanning system wherein a multiple element detector array receives radiation from a scanning rotator having mirror surfaces inclined relative to the axis of rotation. Image distorting effects due to inequality of lines which are concurrently scanned, are offset by individually delaying the electric signals which are individually derived from the detector elements; these delays are related to the instantaneous scanning angle. The electrical signals, thus compensated are converted into a corresponding number of separate light beams which are individually applied to corresponding light inputs of a multiple input optical system comprising a configuration of prisms, which are effective to combine the separate input beams into a single output beam composed of coaxially disposed, rotationally symmetric sub-beams.

Abstract: An apparatus for piped conveyance of material. The material to be conveyed is introduced into a conveyor pipe where it is caused to pass through a blocking section located upstream of a location where compressed air is introduced into the conveyor pipe. In the blocking section, which has an increasing through-flow area in the conveying direction, a material plug is formed by the action of compressed air introduced at the downstream end thereof. The plug seals in a direction upstream and is at its downstream end continuously broken up and blown downstream by means of compressed air.

Abstract: In the manufacture of trains of fastening elements for slide fasteners, flowable synthetic polymer resin is injected into gate or runner channels formed in a cavity wheel and extending beneath one edge of a band enclosing cavities of the cavity wheel such that the flowable synthetic polymer resin flows through the channels into the cavities to form fastening elements.

Abstract: In producing a dyeable coating on a metal article, such as a slider on a slide fastener, the article is coated with a powdered solid polymer resin containing active proton acceptor groups, such as amine groups. The powder coating is heated to convert the powder coating into a polymer film which is capable of being dyed by any of a wide variety of dyes to produce a desired color in the polymer film. During the heating, the temperature is maintained below the temperature at which substantially all the active proton acceptor groups would be transformed or rendered inactive.
