Filed: 1995-10-18
Abstract: Method and apparatus for storing and retrieving routing information in a node of a network, such as an ATM network, are disclosed.  A routing table in each node of the network stores the routing information for each active call connection through the node, for example, identified by a virtual path identifier (VPI) and a virtual channel identifier (VCI). The routing table is indexed by a modified header error control (HEC) value, which may be the actual HEC value associated with a given cell, or a value calculated therefrom.  Upon receipt of an incoming cell at a network node, the modified HEC value is calculated, to access the appropriate entry of the routing table.  The routing table preferably stores a pointer to a memory location, such as a linked list of data structures, storing the actual routing information for each connection. An intermediate node data structure preferably stores the routing information for a particular connection through an intermediate node of the ATM network, while a leaf node data structure preferably stores the routing information for a particular connection associated with a leaf node of the ATM network.  If a data structure in the indicated linked list has a VPI/VCI value matching the VPI/VCI value in the received cell header, the routing information for the next link of the call connection is retrieved, and the cell header information is validated.

Title: High efficiency drive circuit for an active magnetic bearing system
Inventor: MILLER LANCE F
IPC: F16C32/04
Filed: 1995-10-27
Abstract: A plurality of electromagnetics in an array surround a shaft, with current controlled in the coils of the electromagnets to support the shaft at a desired position approximately centered between the electromagnets. Shaft position sensors provide feedback to a control system for modulating the current to the electromagnet coils, which are arranged in pairs on opposite sides of the shaft. A drive circuit for each coil includes first and second switching transistors which connect the coil to the power.supply to transfer a current pulse to the coil. A pair of circulating diodes begin conducting when the transistors turn off, and return power to the supply. A control circuit for the drive circuits interleaves on and off intervals for the coils in the electromagnet pairs so that one coil of the pair is being switched off at about the same time as the other coil of the pair is being switched on. The result is that the energy being returned to the power supply by the off-turning coil is diverted, at least in part, to the on-turning coil, thereby to reduce net current drain from the power supply.

Title: Uv tire protector
Inventor: IAMPEN MARCEL HENRY
IPC: B60C13/04
Filed: 1996-05-14
Abstract: The UV tire protector provides a vacuum molded UV protectant layer ABS shell like cover panel configured to cover the outward facing surface and tread of automobiles, motorhomes, trucks, RV's, airplanes and trailer tires in static use. The shell like cover is maintained in place by a bungi cord positioned across the diameter at the back of the invention, and secured under the axle of the wheel it is attached to so that the cord effectively maintains the cover in place whereby even high winds will not dismember it. The cover extends about the circumference of the tire sidewall and up over covering the tread thus protecting the tire sidewall and tread from the elements and solar UV rays. The design of the tire protector with the cut out portion at the bottom of the tire protector allows for installation without moving the tires either vertically or horizontally from it's supportive position in contact with the ground and allows the tire protectors to be placed inside each other for storage or placement over the spare tire while travelling. The cover is somewhat pliable yet virtually unbreakable; therefore is able to change shape without breaking in the event that the tire loses its air and becomes flat. The tire protector is made of material that can be easily cut if alteration is required to allow the tire protector to fit under skirting that protrudes down over the wheels on some trailers allowing the cover to fit in small clearance levels or on wheels of motorhomes to allow it to fit over the rim of a 19.5 inch rim which may have a rim protrusion beyond the tires edge. The cover is made of an ABS material configured to simulate a tire mounted on a wheel with it's shape, color and design. The color of the ABS is black and molded with a top curvature extending to molded simulated tread around the outside periphery extending about 1 1/2" down the sidewall from the face of the tire protector. Also, on the flat surface from a point at center a designated size for each different size wheel, allows for mylar self adhesive decal consisting of a whitewall ring and a simulated full hub cap or by means of a silk screening process. Within the 5" center of the decal or silk screening process is situated my Registered "Trade Mark", "Sun Buster" in red depicting the diminished sun's bright UV rays.

Abstract: A portable device as disclosed for threshing grain to obtain a sample to be tested, for example, for its moisture content, disease, and protein content.  The grain sampling device includes a housing with a handle enabling the device to be carried, an inlet for sampled grain, a chaff outlet and a collection drawer for the threshed grain kernels. Grain entering the inlet first passes through a declustering device consisting of a first group of stationary, transversely disposed pins and a second plurality of transversely disposed pins that are carried on a rotating first gear wheel. The threshing function is performed between a vertically disposed, stationary surface having a layer of resilient, frictional material, and a second gear wheel disposed in substantially parallel, spaced relation to the stationary surface, and which includes a layer of resilient, frictional material in disk form that defines a movable threshing surface. The space between the two surfaces is adjustable and chosen as a function of the type of grain to be threshed. The threshed grain sample falls into a set of transversely disposed, angular vanes that are continuously reciprocated or shaken to facilitate sifting of the chaff from the grain kernels. A blower emanates a steam of air that passes from below the angular vanes on one side angularly through to the top of the vanes and toward the chaff outlet, carrying the chaff with it for discharge. The grain kernels are of sufficient density to fall through the angular vanes into the collection drawer. A sensor can be disposed in the drawer to determine the moisture content or other parameter of the grain sample.
