    Abstract: A high speed optical scanning system using a circular array of concave reflectors (34, 35) on a reading disc (30) which appears in conjunction with a strip mirror (26) to achieve horizontal scanning is claimed. Such horizontal scanning can be combined with a framing mirror (20) to achieve orthogonal scanning. The system can operate in a "read" mode for scanning a scene or in a "write" mode to create a picture, or can do both modes simultaneously.

    Abstract: The present invention provides an aqueous composition and process for electrodepositing a layer of a ductile, strongly adhering, adsorptive and/or absorptive zinc coating or zinc coating comprising silicon and phosphorous on a metal substrate. The electrodeposition composition is prepared by reacting metallic silicon and zinc with phosphoric acid and an alkali metal hydroxide in the ratio of between 0,4 and 1,3 moles of alkali metal hydroxide per mole of phosphorus acid, and adjusting the solution to a pH of 1 or higher after completion of the reaction. The coating is deposited on the metal substrate by electrodeposition and comprises about 70 to 99,5% by weight of zinc, and about 0,1 to 10% by weight of silicon, and about 0,5 to 20% by weight of phosphorus. The resulting Zn/Si/P coating improves the resistance of the metal substrate to corrosion, wear, galling, stress corrosion cracking and cracking during mechanical forming operations. While essentially all metals of industrial importance may be coated, this process is especially important for ferrous metals, steels, stainless steels, copper, aluminium, chromium and titanium.

    Abstract: In the measurement of the optical transmittance of a sample, a beam which is split from a source of illumination is . directed through the sample and then redirected back through the sample. The redirected beam and a reference beam which is also split from the source of illumination are alternately applied to a photodetector. Both the sample beam and the reference beam pass through a monochromator prior to application to the photodetector. The output of the photodetector is processed by an electronic circuit and applied to a computer. Data representative of the two beams can be compared in order to provide an indication of the amount of light the sample transmits at certain optical wavelengths.
