Abstract: Improved apparatus for heat-treating gelatin capsules containing a medicament to cause heat-seal of the telescoped cap and body wall portions thereof, the apparatus comprising a housing defining an elongate generally cylindrical passageway sloping downwardly from inlet to outlet for receiving and discharging capsules passing therethrough, a capsule conveyor comprising an elongate rotatable shaft mounted on the longitudinal cylindrical axis of the passageway for rotation and carrying a plurality of generally circular conveyor plates, each plate supportably mounted in spaced relation along the shaft and having extending ramp portions communicating with the top surface of the next adjacent plate in the direction of the housing passageway outlet to define a generally Archimedean screw-shaped path for passage of gelatin capsules through the housing passageway from inlet to outlet, air-distributing means comprising an elongate manifold attached to the housing having a first section communicating with the passageway

Abstract: Improved method and apparatus for use in sealing gelatin capsules filled with medicinal ingredients wherein each capsule has a generally cylindrical cap and body arranged with the side wall of the body telescopically within the side wall of the cap to contain the medicament therein comprising an economical and compact wetting device for automatically conveying filled capsules from a capsule-filling machine by pneumatic pressure conveyance through one or more passageways to a wetting location where each capsule is maintained in a generally cap-upright position and metered amounts of a wetting liquid are applied to side wall portions of the body of the capsule adjacent the seam of the cap and body to pass by capillary action into the space between the overlapping cap and body side walls, and the capsules are released from wetting positions in the passageways for further pneumatic conveyance to a point of heat treatment for final sealing of the body and cap portions of the capsule to prevent their separation and

Abstract: According to this invention a razor pack adapted to hold a plurality of razors of substantially identical configuration has a plastic sleeve, which is formed to cover aligned razor heads, the sides of the heads, and a portion of the bottom of the razor. The individual razor units are inserted in the sleeve and the sleeve is attached to a card having a raised rear portion forming an abutment for the back of the sleeve and a closed front portion forming a stop for the razor handles.

Abstract: Foam capsules with telescopically engaged body and cap portions, also known as hard shell capsules, having a special wall structure, obtained by a microdispersion of a gas in a gelatin solution.The capsule body and cap portions are formed by dipmolding the film-forming mixture obtained by a microdispersion of the gas in a gelatin solution; optionally with the inclusion of a plasticizer and/or coloring agent, and/or flavoring agent, and/or foam stabilizer, and/or gelatin extender.By a suitable choice of the gas proportion in the capsule wall and its micronization level, it is possible, within certain limits, to control the capsule wall disintegration speed and its opacity. In addition, inclusion of gas bubbles into the capsule wall lowers the gelatin content for a foam capsule and provides energy saving during the process due to a faster drying of the wall, thereby providing lower cost prices for the production of pharmaceutically acceptable capsules.

Abstract: According to this invention a blade assembly is created featuring pivotally mounted first and second blades with pivot and subsequent change the span of each blade in response to the amount of shaving force generated by the user.

Abstract: This invention relates to a razor blade assembly and particularly to a cap for blade assembly in which a rectangular shaving aid has been attached by means of deformable positioning means extending upward from the cap.

Abstract: Anhydrous emulsion with an oil phase (o) and a hydrophilic phase (p) of water-soluble, but anhydrous liquids, particularly as a filler matrix for medicinal preparations in capsules, which on the one hand does not attack the capsule wall and on the other permits an excellent active agent release.

Abstract: A razor cartridge having a shaving aid secured frictionally to a face-engaging surface of the cartridge including method of manufacture.

Abstract: According to this invention, a pivotally mounted cartridge is provided having pivotal attachment means at or near either end of the cartridge and arcuate cam means which replace the V-shaped cam to provide a pivoting razor wherein the biasing forces are essentially even throughout the arc of the pivot. The balancing of biasing forces result in maintaining the cartridge orientation relative to the face after the initial orientation has been established.

Abstract: A method of securing a strip of solid shaving aid to a face-engaging surface of a disposable razor cartridge.

Abstract: Capsules and other shaped products formed from a moldable starch composition in an injection molding device is disclosed in the present invention. The composition comprising starch having a molecular mass range of 10,000 to 20,000,000 Dalton, and a water content range from 5 to 30% by weight. The starch contains about 0 to 100% of amylose, and about 100 to 0% of amylo-pectin.

Abstract: A moldable hydrophilic polymer composition, preferably gelatin, for use in an injection molding device preferably controlled with a microprocessor. The composition has a molecular mass range of 10,000 to 2,000,000 Dalton or a molecular mass range of 10,000 to 2,000,000 and 10,000,000 to 20,000,000 Dalton. The composition has a water content range from 5 to 25% percent by weight.

Abstract: Single piece capsules, produced, filled and sealed in a single operation, also known as soft shell capsules, having a special foam wall structure, obtained by a microdispersion of a gas in an aqueous mixture of dry gelatin and one or more plasticizers.The capsules are formed by processing, on soft shell capsule manufacturing machines, foamed ribbons, cast from a film forming mixture obtained by a microdispersion of a gas in an aqueous mixture of gelatin and one or more plasticizers; optionally with the inclusion of a coloring agent, an opacifying agent, a foam stabilizer, a gelatin extender, a preservative, a flavoring agent, a sweetening agent, or a drug.By a suitable choice of the gas proportion in the capsule wall and its microdispersion level, it is possible, within certain limits, to control the capsule wall disintegration speed and its opacity.

Abstract: A microscope has a support structure which comprises a base, an upright portion, a cross-head and an objective-turret assembly mounted on an underside of the cross-head. The cross-head is mounted on the upright portion and contains principal components for forming an image. The upright portion and the cross-head define a generally planar division therebetween, whereby a generally planar gas-tight seal can be provided between the upright portion and cross-head. This enables the upright portion and the base to be disposed in a gas-tight chamber while the cross-head is located outside the chamber.
