Abstract: A corona discharge reactor which has a central electrode in the form of a metal rod with radial projections and a cylindrical outer electrode surrounding the inner electrode.

Abstract: An electric heater includes an electric heating coil that extends above the sidewalls of an air flow channel. The coil is formed in sections that extend transversely to the channel and are spaced by the width of a coil section to allow two heaters to be arranged face to face for shipping. This arrangement is very efficient because one of the heaters provides protection to the coil of the other of the heaters to reduce packaging costs.

Abstract: A heating device, such as a heating coil for use in apparatus to be heated, has a removable flexible strip carrier which enables the coil, already supported on ceramic insulators and carried by brackets, to be readily installed in the apparatus. The disposable or reusable strip carrier is notched for supporting the insulators and is easily removed after installation of the device.

Abstract: An electric heater incorporating simple support structure therefor. A frame is insulated from an electric resistance heater coil by insulator supports mounted within beam members of the frame. The supports incorporate structural features enabling the use of simplified supporting beams. The support insulators include additional structural features for retaining the resistance wire in place and for simplified engagement therewith. The insulators may project on both sides of the support beams and retain heater wires in two planes. The support insulators further provide an integrated structure easily fabricated and simply assembled to the frame.

Abstract: A heater assembly includes a housing which both channels air flowing around a heating element and provides support structure for the elements holding the heating element. In one embodiment, a lower U-shaped channel has recesses in opposed sidewalls to engage down-turned ends of holding elements. A second U-shaped channel is attached to form a hollow duct open at opposite ends. In a second embodiment, a U-shaped channel is made of flexible material so that the spacing between opposed sidewalls may be varied. A holding element is secured between the sidewalls by separating the sidewalls to allow insertion of the holding means.

Abstract: A class of 2-substituted benzisothiazolones carrying a nitrogen-containing heterocyclic ring are effective in inhibiting platelet aggregation and are therefore of value in the prophylactic and therapeutic treatment of thrombotic diseases.

Abstract: Pharmaceutical compositions having hypolipidaemic and/or hypoglycaemic activity, contain a substituted (4-carboxyphenoxy) phenyl alkane derivative.

Abstract: Allyloxy benzoic acid derivatives have hypolipidaemic activity, compositions for controlling or reducing serum lipid level in mammals, novel substituted phenoxy and phenylthio allyl compounds and administration of the compositions to mammals in need thereof.

Abstract: Pharmaceutical compositions having hypolipidaemic and/or hypoglycaemic activity, contain a substituted (4-carboxyphenoxy) phenyl alkane derivative.

Abstract: A method of and apparatus for manufacturing stock material from which bags or other containers may be formed is disclosed. A folded plastic film is fed from a stock roll onto a plurality of carrier rollers which support the film in a horizontal position. Simultaneously, a separate closure strip is fed from a second stock roll through a guide block which aligns the strip with a sealing station, the two halves of the closure strip being pressed together to maintain proper alignment. The upper ply of the folded plastic film is fed into the heat sealing apparatus at the sealing station, the edge of the upper ply being aligned with one edge of the closure, and the film and the closure strip are fed continuously through the sealing station where they are welded together. The lower ply of the film web is folded downwardly so that it bypasses the sealing station.

Abstract: A plastic container is provided with a plastic bead seal at the junction of the interlocking fastener and the side edges of the container. The plastic bead seal acts as a barrier to the passage of fluids or contaminating bacteria through the fastener at this junction. A method and apparatus are provided for flowing plastic under heat and pressure into and across the junction to form the bead seal barrier.
