Abstract: Porous, modified polyacrylonitrile-containing membranes suitable for ultrafiltration, processes for their preparation and their use Abstract Modified, polyacrylonitrile-containing membranes suitable for ultrafiltration are prepared by reacting polyacrylonitrile or co-polymers of acrylontrile and other ethylenically unsaturated mono-mers with, successively, hydroxylamine, at least difunctional com-pounds, which act as bridge members, e.g. cyanuric chloride, a poly-functional oligomer or polymer, e.g. polyethyleneimine, and, finally, a reactive compound containing at least one ionic group, e.g. an anionic reactive azo dye. The latter compound must be able to react with the polyfunctional oligomer or polymer and is required only if the said polymer does not already itself contain ionic groups. The novel membranes show good mechanical, temperature and pH-stabilities and are suitable, for example for separating salts from organic com-pounds (dyes) or in waste-water treatment.

Abstract: MOLDED ORIFICE PLATE ASSEMBLY    FOR AN INK JET RECORDER AND METHOD OF MANUFACTURE             Abstract of the Disclosure An orifice plate (10) for use in an ink jet recorder is integrally cast with an orifice plate holder (12),  The orifice plate is formed having a flat, tapered bottom portion containing at least one row of orifices and has sidewalls extending outwardly from the bottom portion at acute angles from horizontal.  The orifice plate holder (12) is formed from a castable plastic material which serves as a damping material.  The holder is cast over and around the sidewalls (11) of the orifice plate to define, with the bottom portion of the orifice plate, a portion of an ink supply manifold.  The damping action of the holder isolates the orifice plate (10) from spurious vibrations which could adversely affect the quality of printing from the ink jet recorder.  Only the desired vibration from the stimulation transducer reaches the orifice plate.  The mass and rigidity of the holder confines the traveling wave induced by the transducer to the orifice plate.

Abstract: ABSTRACT         A method and apparatus for effecting objective quality measurements on speech transmission apparatus allows reproduction of the characteristics of the linear part of a system under test, utilizing only the system input and output signals;  these characteristics are used to generate a refe-rence signal, obtained from the input signal to the system, with which to compare the output signal of the system, and thence to obtain an objective quality measure.         This allows elimination of the effects of the linear characteristics, which affect the objective measure-ment without influencing the quality of system performance.

Abstract: ABSTRACT OF THE DISCLOSURE           With end-to-end electrolytic cells, in particular cells for producing aluminum, high investment and operating costs are incurred by the arrangement of the busbars outside the cell.  The magnetic fields produced by the busbars give rise to streaming of the metal in the cell; by providing direct connections between the individual anodes and the electrically connected busbars running along the side of the cell, in a plane just above the anodes, the costs are lowered and the harmful effects of the magnetic fields diminished; a further effect countering the magnetic forces created by the busbars can be achieved by an asymmetric arrangement in which the busbars are at different distances (a,b) from the cathode bar ends or by connecting an unequal number of cathode bar ends to bus-bars on opposite sides of the longitudinal axis of the cell.

Abstract: Abstract of the Disclosure A seamless aluminum container of the type used for beer, soft drinks, edible goods or the like is provided which container is adapted to be manually axially collapsed in a predetermined pattern to a smaller size when its contents are exhausted, the container collapse being accomplished without the need of any apparatus for guiding the container sidewall collapse and without the aid of any mechanical or fluid pressure device.  The container sidewall. is embossed with a number of adjacent rows of similar, shallow, elongate embossments, adjacent embossments of a row being separated by narrow in-crements of the lateral surface.  Rows of sharply angled rib means separate the rows of embossments.  Increments in a row of embossments are each offset peripherally from increments of an adjacent row.  Manual axial forces collapse adjacent rows of embossments about an interposed rib means to form a collapsed container approximately one-fifth the size of the original container.  The device encourages consumers to recycle aluminum, facilitates the storage and transport of aluminum cans to a recycling station, strengthens aluminum cans in a transverse direction permitting thinner aluminum stock to be used, and conserves aluminum and the energy needed to produce aluminum.

Abstract: ABSTRACT OF THE DISCLOSURE    A child-resistant container and closure combination includes a one piece molded closure threadable on a container neck.  When the closure is fully threaded onto the container neck, a pawl, integrally formed on the bottom of the closure skirt, interlocks with a lug projecting from the container neck to prevent rota-tional removal of the closure.  One end of the pawl is integrally attached to the closure by a relatively thin and flexible bridge, and a slot is formed in the closure skirt immediately above the pawl and bridge.  The flexibility provided by the slot and the thin bridge attachment permits the pawl to be manually deflected upwardly to disengage the pawl and lug, thereby permitting rota-tional removal of the closure.

Abstract: Abstract This invention relates to a method for producing a decorative reflective surface covering with improved adhesion of the various layers, having a backing, metallic areas and a transparent top layer, and the product thus produced.  This product is produced by applying an adhesive on the surface of a backing in regular, spaced intervals, bringing a metal face of a film in contact with the adhesive to secure it to the hacking, removing the metal film whereby the areas in contact with the adhesive remain on the backing and then applying a transparent layer to the surface of the backing covering the remaining metallic areas.
