Abstract: A vial for a dental implant delivery system. The vial includes a clip and a lid that is permanently attached to the body of the vial. The lid disengages from the top of the vial when the body of the vial is squeezed.

Abstract: A self-tapping dental implant includes a body which is substantially covered by a random surface roughening without adversely affecting the cutting edge and thus the amount of torque needed to thread the implant into bone tissue. During the surface treatment process, the cutting edges of the implant are covered with a removable shield. The shield may engage the implant through openings on either side of the cutting edge. The shield is adaptable for use with implants having multiple cutting edges since the shield may include a plurality of arms connected by a base. The shield may be snapped onto the distal end of the implant.

Abstract: A dental positioning guide has two pins connected to a hub section. The pins may be rotated to a plurality of angular positions.

Abstract: The present invention is directed to a novel sustained release matrix and oral dosage form comprising a homogeneous matrix formed from a wet granulation containing an effective amount of a medicament and a polymer blend of hydroxypropyl cellulose and hydroxyethyl cellulose. The present invention also discloses a novel process for making a sustained release oral dosage form comprising wet granulating a medicament with a polymer blend of hydroxypropyl cellulose and hydroxyethyl cellulose to form a homogeneous matrix, wherein the polymer blend is provided in an amount effective to control the release of said medicament, then forming the homogenous matrix into a solid oral dosage form.

Abstract: A hydrostatically releasable coupling assembly for releasably securing a buoyant object to a vessel with a lashing strap. The coupling assembly includes a pair of lashing plates, a cooperative latching mechanism carried by the lashing plates for releasably coupling the lashing plates together and a composite plunger assembly coupled to one of the lashing plates for movement between a release position and a locking position. The plunger assembly has a first diameter portion shaped for release of the latching mechanism for movement from an engaged position to a disengaged position when the plunger assembly is in the release position, and a second diameter portion formed of plastic and shaped to retain the latching mechanism in an engaged position when the plunger assembly is in the locking position.

The finish composition is a liquid at a temperature below about 150.degree. C.

Abstract: A lubricating finish composition suitable for application as a water emulsion to synthetic filaments and synthetic filaments coated with the composition. The composition of the invention comprises:about 60 to about 98.9 weight percent nonionic emulsifier having a melting point less than about 25.degree. C.;about 1 to about 39.9 weight percent lubricant having at least 29 carbon atoms and a melting point less than about 25.degree. C.; andabout 0.1 to about 15 weight percent anionic surfactant.

Abstract: A method of making a screw threaded fastener (1, 10) for fixing cladding to a building includes the steps of applying a mastic covering (5, 15) to a screw threaded portion (4, 13) of the fastener, and applying a non-sticky protective coating (6, 16) to the outside of the mastic covering (5, 15) so as to prevent the fasteners (1, 10) from sticking together during handling and packaging of the same. Preferably the protective coating (6, 16) is as coating of a waxy substance and is applied to the outside of the mastic covering (5, 15) by means of a dipping or spraying process or operation. The fasteners are then easy to use and form a water-tight, moisture and vapor-proof seal with respect to their supports or substrates. The waxy coating (16) may also be applied to the drill point (12) so as to act as a lubricant during driving of the fastener.

Abstract: A high efficiency/low nitric oxide emission gas turbine engine includes an interchanger for cooling a compressed air side stream which is used for cooling the turbine section. The heated fuel is then mixed with steam for injection into a combustor, thereby reducing nitric oxide emissions, while preventing condensation during mixing. Where water is used for injection instead of steam, both the fuel and water are preheated by interchange with the hot compressed gas stream. Preheating the fuel and/or water prevents steam condensate or water from entering the combustor, and does so using heat available within the gas turbine cycle thereby increasing overall turbine efficiency. In addition, utilizing a fuel/air interchanger reduces the size of the heat exchanger and the need for other auxiliary equipment, reducing costs while increasing turbine efficiency.

Abstract: Venom immunotherapy is a highly effective treatment for bee sting sensitive individuals. Treated individuals and those naturally exposed to repeated bee stings, such as beekeepers have been shown to develop anti bee venom anti-idiotypic antibodies. These antibodies can be isolated, monoclonal anti-bee venom antibodies can be generated and used in a diagnostic kit to evaluate whether or not an affected individual has developed effective immunity and to evaluate an individual's risk of sensitivity.

Abstract: A polyamide yarn having on the surface of the polyamide yarn a hydrophobic organic ester dip penetration regulator having a melting point greater than 27.degree. C. and convertible by conventional means into a tire cord having low stiffness and high air permeability and a process for making polymeric tire yarns is disclosed.

Abstract: It is known for colored plastics caps to be pushed by a customer onto heads of metal screws, after the screws have been secured to sheets of colored cladding or roofing. It is also known for the caps to be molded around the screw heads by a manufacturer. In the present invention, a screw/cap assembly is formed by bonding an initially separate cap onto the head of a screw by means of an adhesive, such as an epoxy resin sufficiently strong to allow the screw to be driven while the cap is in place. The intention is that the manufacturer would maintain stocks of the caps and stocks of the screws of different types, and only secure predetermined caps onto the heads of predetermined screws in response to specific orders from customers.

Abstract: A slide mechanism for providing non-binding adjustment of the spacing between the components of an elongated structural member such as the vertical and horizontal frame members of a door or window frame for accommodating different buck widths during installation. The slide mechanism comprises a channel member and a tongue member adapted to slideably engage one another in loosely fitting relation to preclude binding during width adjustment. Each frame member is preferably provided with at least two such sliding mechanisms of which preferably one provides a dimpled channel member for assuring precise transverse registry of the frame components. By dimpling only one such channel member, a degree of non-binding angular or rotational motion between frame components is provided to facilitate easy installation.

Abstract: A spring pivot joint comprises two face plates with heavy serrations or ribs between them, both sandwiched between Belville springs or spring washers, the washers being held in a strongly stressed condition by a hollow rivet. The face plates have integral wings or tabs extending radially beyond the washers for attachment to the companion mannequin parts to be jointed. Since the rivets are hollow, a simple rod can extend through a plurality of them to hold them in coaxial alignment while being attached to the jointed mannequin parts.
