Abstract: A method of incorporating drugs into an implantable medical device. In one variation, water insoluble drugs are used to form crystals within the porous structure of the device. Upon implantation, the drug crystals dissolve slowly and release the drug into the surrounding tissue. In one example, a water insoluble drug is crystallized within the pores of an ePTFE vascular graft.

Abstract: An orbital downhole separator for separating well fluids into constituents of different specific gravities. Specifically, it is designed to separate water from oil or gas. The apparatus comprises a housing with a rotating member therein driven by a motor in the housing. Well fluid flows through the rotating member and is subjected to centrifugal force to separate the components. A flow conditioner is used to facilitate separation. The invention includes several different versions of the flow conditioner including an impeller, a stator and controllers for controlling the speed of the motor in response to signals related to the amount of petroleum in the water.

Abstract: A storage rack vibration isolator for a storage rack system installed on a floor comprising a first mounting plate connectable to the storage rack system, a second mounting plate connectable to the floor. An elastomeric component extending between these mounting plates and is operatively attached to them so that during seismic events the first and second mounting plates remain attached to the elastomeric component as the elastomeric component is placed in shear while the first and second mounting plates are able to move in planes substantially parallel to each other. The elastomeric component comprises at least one elastomeric member made of material that is capable of absorbing and dissipating the energy of ground movement imparted to the storage rack system during seismic events, while the material enables the storage rack system to move a sufficient distance relative to the floor to lower the natural frequency of the storage rack system in at least one horizontal direction.

Abstract: A storage rack system to be installed on a floor has a plurality of columns, is more flexible in a down aisle dimension than it is in a cross aisle dimension, and has at least a first column and a second column adjacent one another in the cross aisle dimension. A storage rack vibration isolator for use with this storage rack system comprises at least one seismic vibration absorption and dissipation structure constructed to be located primarily between the first and second columns to reduce the storage rack system's natural frequency in at least the cross aisle dimension. The seismic vibration absorption and dissipation structure includes a first member connectable to the storage rack system and a second member connectable to the floor. At least one column support assembly is mountable to at least the first and second columns to enable them to move with respect to the floor. A structure limits the movement of the first and second columns to substantially the cross aisle dimension.

Abstract: A downhole fluid flow control device (188) and method for minimizing erosion are disclosed. The downhole fluid flow control device (188) includes a downhole surface (190) subjectable to an erosive stress (196, 198) which may be a moving fluid or an erosive agent, for example. A shape memory alloy (192) is integrated with the downhole surface (190) in order to provide erosion resistance by reversibly transforming from an austenitic phase (194) to a martensitic phase (200) in response to the application of the erosive stress (196, 198). Further, the shape memory alloy (192) reversibly transforms from the martensitic phase (200) to the austenitic phase (192) in response to the presence of sufficient heat.

Abstract: An appliance isolating the forces generated by the appliance from a support surface for a predetermined range of motion of the appliance.

Abstract: A vibration based power generator. In a described embodiment, an electrical power generating system includes a vibrating assembly which vibrates in response to fluid flow across the vibrating assembly. A generator generates electrical power in response to displacement of the vibrating assembly.

Abstract: In one embodiment, the present invention provides an apparatus for creating pulsating fluid flow, including an inlet into which fluid flows and a chamber having an upstream end and a downstream end. The chamber is defined by a pair of outwardly-projecting sidewalls, and the inlet is disposed at the upstream end of the chamber. This particular embodiment further includes at least two feedback passages with opposed entrances at the downstream end of the chamber and opposed exits at the upstream end of the chamber, near where the chamber joins the inlet. At least one feedback outlet leaves each of the feedback passages. A feedback cavity is disposed at the downstream end of the chamber. At least one exit flowline having an exit port leaves the at least one feedback outlet.

Abstract: A games apparatus for use in the game of "keno" includes an enclosure which is rotatable about two perpendicular axes. The enclosure consists of two spaced chambers lying along one of the axes with the chambers being connected by a passage which will allow objects contained within the chambers to pass between the chambers. Upon rotation of the enclosure about the two axes, the objects are arranged randomly so that a random sample of the objects may be selected from the enclosure.

Abstract: A steering system for a guided vehicle comprises a coupling device for coing the steering axle actuating linkage both to a detector for guiding the vehicle along a guidance reference member and to a steering gear, the coupling device comprising first and second elements respectively mechanically linked to the steering gear and the detector and mounted for movement along first and second guide bars, each element being movable between first and second positions on its guide bar, the guide bars being so coupled to the actuating linkage that an element in the first position transmits movement to the actuating linkage and in the second position is ineffective to transmit such movement.
