Abstract: There is provided novel pharmaceutical compositions containing tyloxapol as the active ingredient. These formulations comprise tyloxapol at concentrations above 0.125%, preferably from about 0.25% to about 5.0%. In addition, the invention encompasses pharmaceutical compositions having reduced hypertonicity which compositions comprise tyloxapol in pharmaceutically acceptable solutions without significant concentrations of hypertonic agents or other active ingredients NaHCO.sub.3, or active phospholipids, such as DPPC. The less hypertonic formulations allow one to derive all the benefits of the active ingredient tyloxapol, such as its reduced toxicity and enhanced half-life, while avoiding or reducing side effects, such as bronchospasms, associated with the various hypertonic agents or other active ingredient agents.

Abstract: A radome structure has an outer first layer of a fiber-reinforced composite material of quartz fibers in a noncrystalline cured oligomeric cyanate ester pre-polymer. A second layer of a syntactic foam underlies and is bonded to the first layer. A third layer of the same fiber-reinforced composite material (although possibly of different thickness) underlies and is bonded to the second layer. A fourth layer of the syntactic foam underlies and is bonded to the third layer. A fifth layer of the same fiber-reinforced composite material (preferably of the same thickness as the first layer) underlies and is bonded to the fourth layer. The structure is formed by layup of the first layer inside a female mold, and successively shaping the remaining layers and tacking them to each preceding layer. The shell produced in this manner can be joined to conforming shells.

Abstract: An apparatus and method for winding tissue webs into a parent roll includes a rotatable reel drum having a flexible outer shell for engaging a web of tissue paper against a reel spool. A deflection sensor is mounted adjacent to the inner surface of the outer shell for measuring the amount of deflection of the flexible outer shell caused by the paper roll. The amount of deflection is related to the pressure at the nip point and, by moving the reel spool and flexible reel drum away from each other as the diameter of the paper roll increases, the pressure can be controlled at a desired level. Accordingly, a predetermined light nip pressure can be applied to the roll as the tissue web is wound thereon and large parent rolls of high bulk tissue can be manufactured with desired properties when unwound.

Abstract: Microwave devices incorporate at least one photosensitive baffle that is selectively illuminated changing the baffle's electronic characteristic from being transparent to being reflective of microwave energy. The baffle serves as a gate, tuning element, reflector and the like. Various forms of photosensitive baffles and microwave devices are presented.

Abstract: A bioreactor, in particular for a microgravity, comprising at least one cell culture chamber, an oxygen supply and an agitator for a cell culture. In particular, the chamber includes two housing elements (1, 2) having a first (1', 9) and a second (2', 9') wall region, as well as a first (3) and a second (4) separating element extending from respectively the first (1', 9) and the second (2', 9') wall regions in the direction respectively of the second (2', 9') and the first (1', 9) wall regions. The separating region or regions of the separating elements has (have) a height (h) less than the distance (D) between the first (1', 9) and the second (2', 9') wall regions. The agitator includes a first and second devices (7) for moving the two housing elements (1, 2) with respect to each other.

Abstract: An arrangement (10) for mounting a lens for axial movement comprises a housing (12) defining an axially extending bearing surface (14) and a lens carriage (16) including least three circumferentially spaced bearings (20, 21, 22) in contact with the bearing surface (14) and permitting axial movement of the carriage (16) relative to the housing (12). One of the bearings (20) is biassed towards the bearing surface (14). In use, the arrangement (10) maintains a three-point contact between the lens carriage (16) and the bearing surface (14) despite geometrical variations in the surface.

Abstract: A method of manufacturing multi-ply tubular containers for food products is provided including the steps of advancing a continuous body ply formed of paperboard towards a shaping mandrel and advancing a continuous polymeric liner ply adjacent to one surface of the paperboard body ply. The polymeric liner ply includes a moisture barrier layer and an adhesive layer defining one surface of the liner ply, wherein the adhesive layer includes a polymeric adhesive which is activated at a predetermined activation temperature. The body ply is heated to a temperature above the activation temperature of the adhesive, and the body ply and the liner ply are then passed in face-to-face contact through a nip to adhere the liner ply to the body ply. The body ply and liner ply are then wrapped around a shaping mandrel to create the tubular container.

Each of the bags in the pack have front and rear walls integrally joined at their sides and secured together at their bottoms and define an open mouth portion at the top of the walls. A detaching central tab is formed at the top of each of the bag walls and each has an aperture therein for mounting the tabs on the rack retaining device.

Abstract: A sterile, pyrogen-free fluid replacement solution for intravenous infusion is disclosed that consists essentially of a physiologically acceptable sodium salt, a physiologically acceptable potassium salt, an osmolality control agent, and, optionally, a component selected from the group consisting of a physiologically acceptable calcium salt and a physiologically acceptable magnesium salt.

Abstract: A cosmetic container for a cosmetic, such as lipstick, which permits the cosmetic to be extended and retracted for application and which permits a low swivel torque, which operates smoothly, and which substantially minimizes or prevents "push-back". The container includes a uniquely configured lug which cooperates with a helical channel of a tubular sleeve to prevent push-back which is defined as unwanted movement of the lipstick within the container caused by downward axial force which results when the lipstick is applied. According to one embodiment, the lug includes an end surface portion having a compound surface wherein one portion thereof is parallel to the longitudinal axis and another portion thereof is positioned at an acute angle to the longitudinal axis. The compound surface also includes a line of intersection defining the portions which is, itself, angularly positioned relative to a plane normal to the longitudinal axis.

Abstract: In a crack arresting structure the crack arresting feature is located in the transition from one thickness to another, or a region of increased thickness can be intentionally introduced for the purpose of inhibiting crack growth propagation. The crack arresting feature comprises two different structural configurations. These structures include a thickness transition region where a portion of the structure is plastically deformed at or immediately adjacent to the thickness transition region. Alternatively, an overhang is provided where an appendage to the thicker part extends back over the thinner part at a thickness transition region. A high strength fiber or wire, preferably of non-constant cross-section may be inserted into a gap underneath the overhang and held in place by crimping due to plastic deformation. Fiber or wire reinforced interface may be adhesively bonded into place prior to or in lieu of deformation or crimping.

Abstract: A cosmetic container having an inner sleeve and cosmetic carrier which cooperate to provide requisite torque and prevent angular movement therebetween. The cosmetic carrier includes a plurality of radially outwardly extending, vertical ribs and the inner sleeve includes a plurality of radially inwardly extending, vertical ribs. The cosmetic carrier is positioned within the inner sleeve wherein the ribs of one member cooperate with the ribs of the other. When the inner sleeve is rotated so as to extend or retract the cosmetic carrier, the inwardly extending ribs of the inner sleeve engage the outwardly extending ribs of the cosmetic carrier. When the cosmetic carrier is fully extended or fully retracted, the inwardly extending ribs of the inner sleeve and the outwardly extending ribs of the carrier are disengaged.
