Abstract: There is now provided a beverage bottling plant for filling bottles with a liquid beverage filling material in a beverage bottling plant, and a cleaning device with a pair of nozzles transversely disposed with respect to one another for introduction of cleaning medium into a stream of air and for introduction a stream of air into a cleaning medium.

Abstract: The present invention is a protective rotatable enclosure for the sensitive internal electrical and mechanical components of a surveillance camera scanner system that is particularly suited for deployment in an inverted position. The invention includes a sloped mounting base with an optional annular lip, a stepped relationship between the mounting base and the rotary spindle, and at least one O-ring seal. The invention also has the ability to set and adjust the limits of the scanning arc(s) of the scanner enclosure through the use of one or more fixed-position magnetically operable electronic sensors located inside the enclosure which are triggered by one or more external magnetic actuators adjustably deployed on the rotatable enclosure.

Abstract: A method and apparatus for the carbonization of polyacrylonitrile (PAN) precursor fibers. The apparatus comprises a furnace, or series of furnaces in side-by-side arrangement. Each furnace includes a heater, an air inlet and an air diffusion plate. The fiber is located in the furnace above the air diffuser plate, such that heated air is evenly dispersed over the fibers. The method generally comprises the steps of heat treating the PAN precursor in an oxidizing environment to stabilize the fiber, and then further heat treating the stabilized fiber in an oxidizing environment to carbonize the stabilized fiber. The method can be carried out in a single furnace, or can be carried out in a series of furnaces in a continuous process.

Abstract: Photoresist formulations for forming relief structures from highly heat-resistant polyimide polymers, containing in an organic solvent in essence at least(a) one polyamide ester prepolymer carrying photopolymerizable radicals(b) a radiation-reactive copolymerizable unsaturated compound(c) a photosensitizer(d) a photoinitiator(e) a leuco dye, exhibit enhanced photosensitivity if they contain as the photoinitiator a compound of the type of the N-azidosulphonylarylmaleimides and as leuco dye a compound of the type of the triarylmethanes.

Abstract: Perdeuterated methacrylates of a high degree of deuteration can be obtained by a process for the preparation of perdeuterated methacrylates from hexadeuteroacetone by conversion into the corresponding cyanohydrin, subsequent elimination of water, hydrolysis of the cyano group and esterification with perdeuterated alkanols, the conversion of hexadeuteroacetone into the cyanohydrin being effected by reaction with trimethylsilyl cyanide to give 1,3-hexadeutero-2-(trimethylsiloxy)-2-cyano-propane and subsequent hydrolytic elimination of the trimethylsilyl group.
