Abstract: TREATING PULP WITH OXYGEN                 ABSTRACT OF THE DISCLOSURE         A wood pulp slurry is treated with oxygen in a mill with little change to the process or structure of the mill.  No special pressure tanks are required. The consistency of the pulp need not be altered for the treatment step.  It may be treated at the usual process consistency of the pulp; e.g., it may be treated at the usual consistency of the pulp leaving a washer (71') or the subsequent steam mixer (86) without additional dewater-ing or additional dilution.          The oxygen is added into a closed section of the system so that it cannot immediately vent to the atmos-phere.  Alkali should also be present when the oxygen is mixed with the slurry.  The mixing should occur near to the point of oxygen addition.      The oxygen is inserted into the pulp slurry and mixed with the pulp slurry between a pair of washers (71', 91').  The second washer (91') may be a vacuum, pressure or diffusion washer.          The mixing occurs in a relatively small mixer that intensively mixes the slurry and gas.  The mixer has a mixing zone with a swept area of 10,000 to 1,000,000 square meters per metric ton of oven-dry pulp. A preferred range is 25/000 to 150,000 square meters per metric ton of oven-dry pulp and an optimum range of around 65,400 square meters per metric ton of oven-dry pulp.          Specific mixer designs are also disclosed.

Abstract: Abstract The present invention relates to medical polymers and devices made therefrom, and is based on the discovery that certain carboxylate antimicrobial agents can be releasably incorporated into permeable polymers.  The walls of medical devices such as catheters can be fash-ioned from such polymers.  In use, the antimicrobial agent diffuses from the walls to the surface of the device to form an antimicrobial barrier on the surface of the device and a zone of microbial inhibition on tissue surfaces surrounding the device, thereby effectively supplementing the body's own natural microbial barriers where they have been compromised.  The bacterial con-tamination-resistant carboxylate-plus-polymer compositions herein can be used in the manufacture of a wide variety of medical devices, especially urinary catheters, intra-venous catheters, wound dressings, and the like.

Abstract: ELECTRONIC KEYBOARD SYSTEM AND METHOD FOR REPRODUCING SELECTED SYMBOLIC LANGUAGE CHARACTERS            Abstract of the Disclosure A method and apparatus for electronic typing of symbolic language texts is disclosed.  A twelve-key keyboard utilizing a modified four-corner identifier system permits construction of a first shape identifier code utilizing indicia which represent the shape of a character to be reproduced.  Alternatively, a phonetic identifier code uti-lizing a phonetic alphabet can be constructed to represent the character.  The identifier code is used to select one or more characters stored in a data processing system memory, each character selected by the shape identifier code having the same four-corner identifier indicia, and each character selected by the phonetic identifier code having the same phonetic spelling.  Only a limited number of characters can be uniquely identified by either the four-corner system or the phonetic spelling system; for the remainder of the characters, a single set of indicia or a single phonetically spelled word can represent two or more characters, and thus ambiguities exist in the selection process.  If the word to be typed comprises a single character, means are provided for manually disambiguating the characters selected by the indicia code.  If the word consists of two syllables, means are provided automatically to disambiguate the word in ac-cordance with known character pairings.  If more than one such pairing exists for a given identifier code, additional means are provided for manually disambiguating the pairs.     Means are provided for storing and/or displaying the unique character or character pair which results from the selection process.

Abstract: ABSTRACT An improved negative glow discharge hollow cathode device for generating laser radiation. The device comprises a hollow cathode assembly substantially surrounded by an anode envelope having a body section and a pair of end sections, each of the end sections terminating in a radiation transmission member. The metal laser medium is enclosed in the vicinity of the perforations in the cathode such that the metal vapor can be readily introduced into the cathode central region effectively and efficiently. The anode to cathode discharge paths is reduced by the use of an anode screen such that the glow discharge is directed into the cathode central region with a controlled discharge gap for optimum pressure and confined negative glow discharge within the cathode. The metal laser medium, in the form of a metal foil or sheet, is lined adjacent the cathode outer surface and perforated cathode holes in the lower half portion of the cathode. Metal vapor is released into the cathode by evaporation due to sputtering and heating of the discharge, the metal vapor being confined within the cathode by the cataphoretic pumping from the anode screen and recondensation onto the cathode inner surface. An insulation sleeve adjacent the metal foil has one row of equally spaced slots and provides a uniform discharge gap and path along the cathode by aligning the slots with the perforated holes on the upper portion of the cathode.           The anode screen is wrapped around the insulator sleeve and electrically connected to the outer vacuum anode envelope. The glow discharge is maintained from the anode through the slots into the cathode inner space. Since the cathode outer surface is insulated by the sleeve, the discharge is effectively confined.

Abstract: ABSTRACT     A nutating traction drive in which external rolling surfaces on a one-piece biconical body are retained against axially spaced internal ring surfaces at diametrically opposite points of contact by a mechanism acting between a body which is rotatable on the axis of the ring surfaces or a first axis and which carries the biconical body on a second axis inclined with respect to and intersecting the first axis at a point of axes intersection located midway between the ring surfaces and points of contact.  The mechanism includes a pivotal member having a fulcrum point eccentric from the first axis or displaced from a plane containing both the first and second axes so that a torque reaction to rotation of the carrying body by the biconical body results in a force attempting to increase the angle between the first and second axes.  A preloading device acting to rock the pivot member in one direction provides a preload biaz of the rolling surfaces against each other whereas an unloading device operating to swing the pivot member in the opposite direction results in a removal of normal friction force between the engaged rolling surfaces.

Abstract: ABSTRACT IMPROVEMENTS IN OR RELATING TO A METHOD AND APPARATUS FOR PRODUCING MULTI-LAYER EXPANDED FILMS Method and apparatus for forming multi-layer expanded film. A base film extruded by a die (6) is coated, immediately down-stream of the die mouth (5), by a further layer of fluid propelled from a manifold (16) through a metering orifice (19). The combination of manifold and metering orifice is necessary to permit accurate control of the flow rate of the fluid and hence of the thickness of the coating, and the mouth of the die and the metering orifice must be very close so that the base film is as resistant as possible to deflection by the impact of the coating fluid, and so that contact takes place before any substantial expansion has taken place. The downstream end of the resulting multi-layer tubular film is then held closed in known fashion and the closed tube is expanded by air under pressure admitted by an opening (7) in the die (6).

Abstract: ABSTRACT OF THE DISCLOSURE:           Continous monitoring of variations in the concentrations of individual components in gaseous mixtures such as, more particularly, gases released from volcanic vents, is achieved in the field with consistently high precision, namely about 2 ppm, over extended periods of time, while the time lag for detecting a variation is minimized.  On-site measurements are made with a portable apparatus, comprising a sampling probe from which the gas is led to an expansion enclosure maintained at a regulated pressure of about 10-2 to 10-1 millibar.  From this enclosure, the gas is metered by means of a piezoelectric valve into the analysing chamber of a quadrupole mass-spectrometer Several units operating in the field, directly over the volcanic vents, may be connected to a central date processing station, so as to derive useful correlations for predicting future volcanic activity, for monitoring geothermal sources, and for detecting gas-release anomalies for purposes of geophysical exploration.
