Abstract: "METHOD AND APPARATUS FOR ANALYSIS"    ABSTRACT OF DISCLOSURE           This invention relates to a method and to apparatus for chemical and biochemical analyses which employ an energy-transmissive core and may employ one or more sheaths which selectively absorb, react with, and/or filter an analyte or a product of an analyte.  The core is transmissive to a chosen energy carrier and it has an inlet end and an outlet end.          Between these ends it has an extended length.  The passage of energy through the core is modified by reason of events which occur in one or more of the sheaths or in the case where no sheath is employed, by reason of events which occur in an ambient fluid.  The resulting modification of the transmitted energy is a measure of such events which in turn are a measure of the analyte.  The energy may be any of several types of energy which can be transmitted through the core from end to end and which is susceptible to modification by reactions in the sheath or sheaths or ambient fluid.  The energy may be electromagnetic, electrical or sonic.  In the method aspect of the invention a permeable core may be used which is bare, i.e. without a sheath, and exposed directly to an environment, e.g. the air or an industrial fluid.

Abstract: MULTI-DIRECTIONAL CURSOR MOTION                 ABSTRACT OF THE INVENTION      Operator keystrokes are processed in a text processor system to move a cursor on a display screen in either a vertical or horizontal direction or both without limitation as to the location of text.   keystroke data is processed under  the control of programs  stored  in a random access memory.  For a cursor motion, the random access memory of the system is structured to include a text storage buffer and a display control block both interconnected to an applications program and a display access method program.  Data is stored in the text storage buffer in an unformatted configuration and the programs equate a contextual cursor address with a spatial cursor position.   After running the display access method  program  in  accordance  with  application  program commands, a  refresh  buffer  provides  display  signals  to visually present by means of the display screen a cursor at an identified position in text.

Abstract: ABSTRACT A device for the continuous dewatering of a fibrous material web, preferably in the form of a double screen paper making machine, has in the preferred embodiment two endless screens, namely a lower screen and an upper screen.  The lower screen upon which the paper web is formed, runs together with the upper screen onto the lower area of a dewatering roll located within the loop defined by the upper screen.  The two screens run around the lower rising quadrant of the dewatering roll and down from this and wrap around the upper area of a support roll that is arranged within the lower screen loop. The roll cover of the dewatering roll has recesses that pick up water in the wrap around area of the two screens and throws this off behind the run off point of the screens from the roll cover into the interior of the web loop of the upper screen.  In the direction of movement of the web behind the support roller, there is a trap container for the water that is thrown off.  This has a cover that is curved upwards and extends counter to the direction of movement of the screen into the wedge shaped gap that is located between the dewatering roll and the screens.  The trap container is divided into two chambers, these extending transversely to the direction of movement to the screens and each having a side outlet channel.  The majority of water thrown off from the fibrous web passes in dense streams through the upper screen and along the cover wall into a main chamber where the streams are diverted into the direc-tion of the outlet channel with the help of guide blades.  A minor portion of the water thrown off passes through the upper screen as a mist carried into the other chamber.

Abstract: ABSTRACT OF THE DISCLOSURE A roller used as a press or calender roller in a paper machine is compensated for deflection and end-loaded.  The roller has a stationary axle with spaced opposite ends at which the roller is loaded and a cylindrical shell rotatably mounted on the axle.  The axle has a magnetic core portion within the shell having pole shoes spaced from the shell by air gaps and magnetiz-ing coils of electrical conductors thereon at corresponding ones of the pole shoes.  The coils produce a manetomotive force and are positioned in a manner whereby magnetic flux passing throught the air gaps between the pole shoes and the shell creates a compensating force field between the shell and the magnetic core.          The roller has an inner part of the shell consisting of a stack of sheets of magnetically well-conductive material separated from each other by electrical insulation thereby reducing eddy current losses.

Abstract: ABSTRACT OF THE DISCLOSURE    A CO2 supply system for a carbonator includes a CO2 cylinder containing a combination of liquid carbon dioxide and gaseous carbon dioxide under pressure at approximately 900 p.s.i.g., an openable end including a valve element disposed in an elongated extension of that end, an adaptor socket for receiving the elongated extension and supporting the cylinder, a pressure regulator connected to the adaptor and a hose coupling the same to a carbonator tank and an elongated tube extending from the open end of the cylinder toward a closed end thereof and terminating at a position spaced from the closed end.  The elongated tube is open at both ends to permit the flow of liquid or gas therethrough, depending on the orientation of the CO2 cylinder.  In order to dispense CO2 gas to a carbonator, the CO2 cylinder is disposed with its open end down and plugged into the adaptor socket.  In this position, CO2 gas is present in the head space of the CO2 cylinder adjacent the closed end thereof. Accordingly, this CO2 gas will flow through the elongated tube out through the open end of the container and the pressure regulator to the carbonator tank.  However, if the CO2 cylinder is inverted with the closed end on the bottom and the open end on the top, the liquid and gaseous phases within the cylinder will be reversed, permitting only liquid to be dispensed from the CO2 cylinder.  Thus, the CO2 cylinder of the present invention will operate satisfactorily to dispense CO2 gas only with the open end on the bottom and plugged into the adaptor socket.
