Abstract: An spring apparatus for use with an automatic swinging door closure system wherein the system includes a motor linked to a door via a gear train and a drive arm, the train including a plurality of gears including a first gear adjacent the motor, the motor driving the gears to move the door in either a clockwise or counter-clockwise direction and the apparatus for driving the gears in the direction opposite motor direction when motor power is cut off, the apparatus including a spring mounted within a housing which is linkable to the first gear in a first orientation to cause clockwise door movement and is linkable to the first gear in a second orientation to cause counter-clockwise door movement, the apparatus is easily modifiable so as to be configured in either of the first or second orientations and also includes a tension adjusting mechanism for adjusting spring tension.

Abstract: Antimicrobial compositions comprising at least two antimicrobial agents exhibit reduced MIC values relative to the MIC for the agents making up the combination when measured alone. The compositions are useful as therapeutic agents such as in oral hygiene products.

Abstract: The present invention is embodied in an ink well assembly for use with a transfer pad or tampon printing machine having a image plate. The ink well assembly of the present invention includes an ink reservoir for holding ink, a receiving area for securing the image plate in a sealed relationship with the ink, a plurality of adjusters for securely urging the image plate within the receiving area, and a plurality of fasteners unexposed to the ink. The unexposed fasteners secure component parts without exposing the fasteners to the ink to allow easy set up, cleaning, disassembly and reassembly, elimination of ink leaks, and incorporation with the pad printing machine without significant machine downtime.

Abstract: A bracket is provided that is rigid and can be attached to a solid surface. The bracket allows a vinyl fence post to be fitted over and locked in place thus avoiding the necessity of pouring concrete into the post to provide a rigid post. The bracket has a base plate with bolts or anchor bolts that connects to a solid surface, an elongated member extends up from the base plate and has a cross-section to provide a sliding fit within a fence post. An expansion mechanism is provided at the top of the longitudinal member with tapered sides extending from within the longitudinal member to a larger cross-section than within the longitudinal member, and a tensioning bolt between the expansion basket and the bracket to force the expansion basket within the longitudinal member and expand the bracket to grip a fence post positioned over the longitudinal member.

Abstract: A microcapsule for use in degrading a hydrocarbon comprising a core material, a coating material, and at least one microorganism capable of degrading said hydrocarbon, said core material comprising a lipophilic material containing nutrients necessary for the sustenance of said microorganism, said coating material being water-insoluble, and said capsule having a density such that said microcapsule is kept in close proximity to said hydrocarbon to be degraded whens said microcapsule is applied thereto; and the method of using the microcapsule to degrade hydrocarbons.

Abstract: A biodegradable composition comprising a polymer matrix having distributed substantially uniformly therethrough hollow sphere-like inclusions or microcapsules, said polymer matrix consisting essentially of a water-soluble polymer/polymer-compatible salt complex with said salt present in an amount sufficient to render said polymer insoluble in water and products made by shaping such composition.

Abstract: A trailer for attachment to a two-wheeled vehicle. The trailer has a relatively low center of gravity and a single pivoting trailing wheel.

Abstract: A O.sub.2 /CO.sub.2 /pH compound gas probe comprising a single optical waveguide and a method for making the same. The optical waveguide carries light signals at different wavelengths for monitoring oxygen concentration, carbon dioxide concentration, and pH levels. The probe is designed so that light signals used to monitor carbon dioxide concentration are optically prevented from impinging on the sensor used to monitor the pH level.

Abstract: A cable terminating cabinet for terminating optical waveguide cables contains an array of optical waveguide connectors one side of each connector having a pigtail fiber attached to it, the pigtail fibers being spliced to waveguides of a cable terminated at the cabinet. Waveguides terminating at the other side of the connector are taken to electro-optic units where optical signals within the fibers are converted into corresponding electrical signals. The cabinets find application either at a central office cable terminating frame or in a test access unit at a location remote from the central office. The connectors are mounted in a panel which is exposed when a front cover of the cabinet is removed, the panel being pivoted about a vertically orientated hinge to expose a stacked set of splice organizing trays at the rear of the cabinet. Ready access is therefore possible to both the connector panel and the splice organizing trays.

Abstract: The present invention is directed to a device (50) for providing filtration of air. The device includes a body (70) and a cover (72) with each having endless mating structure (76) and (78) which may be welded together thereby mechanically pinching a flat sheet filter media (74) and holding it in place. The cut edge of the filter media (74) is encapsulated. The filter media (74) is held outwardly from bottom (92) of body (70) by gussets (90) to provide sufficient area for air to pass through. Inlet openings (110) are provided between top (94) and endless mating structure (78) in a fashion which allows top (94) to be attached to a flat wall of a sealed housing of a type used for disk drive systems.

Abstract: Forming an encapsulated splice region between cable ends in which the splices formed by connecting conductors together are laid onto the jacket of a cable and are sealed from one another. A layer of resilient tape is wrapped around the cable and over the sealing material to seat it tightly onto conductors leading to the splices. A molded encapsulation is then formed around the splice region and the resilient tape, still in resilient condition holds the tight seal onto the conductors and prevents moisture from within the cables from reaching the splices.

Abstract: A method of forming a molded encapsulation around a sealed spliced region between two cables in which the cables pass through a mold with the splice region in the mold cavity and correctly centered before molding. To allow for the centering operation to be performed, apertures are provided in the mold. Hook members are passed through the apertures. These hook members are caused to engage both inner and outer mold surfaces and they also engage tie means at two circumferentially spaced positions around the splice region to centralize the region within the cavity. The mold is then filled with molten material and the hooks removed from the apertures with the material still molten. Hook removal may take place either when the cavity is completely filled or after sufficient molten material has entered the mold to hold the splice region in fixed position. The method is applicable to low pressure molding, i.e. below 100 psi and preferably below 50 psi.

Abstract: A packaged optical fiber splice is held in a retainer formed by two pairs of cantilever members having inwardly facing ribs at their top edges. The members of a pair are spaced so that after pushing a packaged splice between the ribs, deforming the members slightly, the packaged splice is freely positioned between the cantilever members which are at least substantially stress free. The splice is retained by the ribs. A slot in the base of the retainer provides a seating for the lower edge of the splice and restrains the splice against longitudinal movement. A plurality of retainers are provided in an organizing tray.
