Abstract: Self relieving seals of this invention comprise an elastomeric seal body having a first sealing surface and a second sealing surface for contact with respective drill bit sealing surfaces. The seal includes a pair of external surfaces that each extend along the seal body between the first and second sealing surfaces. The seal includes one or more relief ports that are disposed through the seal body and that have openings through each of the seal body external surfaces. The relief port can be specially configured, e.g., have different diameter sections of constant or variable dimensions, to provide a degree of control over pressure equalization through the seal body when the seal is loaded within the drill bit. The seal may include an element, e.g., solid, tubular, or porous, disposed within the relief port to provide a further desired degree of control over pressure equalization through the seal when the seal is loaded within the drill bit.

Abstract: Truss assemblies of this invention comprise elongate chord elements having opposed first and second axial ends. Brace elements are used to orient and connect together the chord elements in a desired spatial orientation and have a plate structure. The brace elements comprise chord receiving openings disposed therethrough that are sized to accommodate placement of a respective chord element therein, and that are positioned to provide the desired spatial orientation between the chord elements. The chord element receiving openings and define a portion of the brace element that surrounds the chord element disposed within the opening. A connector is rotatably attached to an end of the chord elements to facilitate attaching the truss assemblies together for the purpose of forming a desired truss system.

Abstract: A pressure capsule embedded in a pacemaker lead to monitor intracardiac chamber pressure is described. This pressure monitor capsule provides highly accurate pressure readings while insuring a high integrity seal against bodily fluids and tissue growth. The capsule is intended to be embedded into a pacemaker cardiac lead or a catheter with the distal (Tip) isolation diaphragm sensing pressure, coupling the pressure through an air column to a protected sensing MEMS device and providing a secure fluid seal to the lead walls. The proximal (Back) end of the capsule provides the electrical interface through the lead to the pacemaker pulse generator.

Abstract: Elastomer-modified Epoxy-polysiloxane compositions of this invention are prepared by combining a silicone intermediate, with an epoxy resin, an elastomeric resinous intermediate, a polyfunctional amine, an optional organometallic catalyst, and optional fillers, pigments, and processing agents. The composition is prepared using a sufficient amount of water to promote hydrolysis of the polysiloxane and the polycondensation of the silanols produced by such hydrolysis. In its cured form, the epoxy-polysiloxane composition exists as a uniformly dispersed arrangement of linear epoxy chain fragments that are cross-linked with a continuous polysiloxane polymer chain, wherein either or both of the epoxy and/or polysiloxane polymers are elastomer modified to provide coatings and floorings having significantly improved properties of impact resistance, flexibility, crack resistance, and abrasion resistance with compared to conventional epoxy systems.

Abstract: A window assembly for a public transportation vehicle that permits rapid removal and replacement is disclosed. The vehicle has a sidewall with a window opening. One or more frame members are attached within the window opening. The frame members are adapted to comprise one or more apertures. One or more retainers are adhesively attached to the inner surface and towards the outer periphery of a piece of glazing. The retainers have protrusions that can extend through the apertures in the frame members and engage therewith when the piece of glazing is positioned adjacent to the window opening. Removable fasteners can be attached to the protrusions so as to detachably secure the piece of glazing and the retainers to the frame members. This allows easy removal and replacement of the piece of glazing from the window opening of the sidewall of the vehicle.

Abstract: A device to mix and extrude various ingredients including pastas, pastries, baked goods, hors d'oeuvres, and cookies. The device includes novel measuring, mixing and extrusion arrangements including: an automatic measuring cup; a way to continuously mix and extrude ingredients without intervening cleanings; a mixing and extrusion feed for handling different consistencies of ingredients; an integrated automatic cutter; motor cooling and extruded ingredient drying; as well as various safety devices.

Abstract: An electrophoresis apparatus is generally disclosed for sequentially analyzing a single sample or multiple samples having one or more analytes in high or low concentrations. The apparatus comprises a relatively large-bore transport capillary which intersects with a plurality of small-bore separation capillaries. Analyte concentrators, having antibody-specific (or related affinity) chemistries, are stationed at the respective intersections of the transport capillary and separation capillaries to bind one or more analytes of interest. The apparatus allows the performance of two or more dimensions for the optimal separation of analytes.

Abstract: A method of forming a printable media sheet construction, including: (a) cutting cross-direction lines through a cardstock web; (b) after step (a), laminating a plurality of strips to the web; and (c) after step (b), cutting machine-direction lines through the web and to the strips on the opposite side of the web.

Abstract: An improved method for cleaning and sterilizing medical and dental instruments (16) employs the use of a banding device (10) to segregate and hold together medical or dental instruments (16) after use in a particular procedure. The banded instruments (16) are then cleaned and sterilized. This method essentially eliminates the time and effort formerly required when unsegregated instruments were mixed with other instruments for cleaning and sterilization and then stored according to the particular procedure for which they are intended and/or according to the intended particular user thereof.
