Abstract: CONTINUOUSLY ADAPTIVE PHASE LOCKED LOOP               SYNTHESIZER           Abstract Of the Invention A continuously adaptive phase locked loop synthesizer is disclosed in which error correction pulses from a phase detector are separated into narrow pulse width and wide pulse width pulses. The wide pulse width pulses are coupled to the loop filter to enable a rapid charge of the loop filter. The narrow pulse width pulses are filtered by a narrow bandwidth filter to provide a VCO control Voltage on a control line connected to the output of the loop filter before being applied to the loop filter thus enabling a slow charge of the loop filter. The narrow bandwidth filter is decoupled from the control line but referenced to the control line voltage.

Abstract: Each unit number of coins to be stacked and wrapped are centrifugally aligned on a rimmed turntable and fed in a row along a horizontal coin guideway to a stacking position, where the successive coins are stacked by a toothed stacking wheel capable of placing each new coin under the preceding one.  Thus the coins are stacked on, rather than under, the plane of the coin guideway with a view to the reduction of the vertical dimension of the machine to a minimum.  Disposed around the stack of coins thus formed are a set of parallel wrapping rolls at least one of which is displaceable for rotatably engaging the coin stack between itself and the other wrapping rolls. With the forced rotation of the wrapping rolls together with the coin stack, a piece of wrapper strip is wound around the latter, and the side edges of the wrapper strip are folded against the opposite ends of the stack.  The wrapped stack of coins is ejected downwardly.

Abstract: A headbox apparatus is disclosed for ejecting stock in a forming section of a papermaking machine.  The apparatus includes an enclosure for the stock, the enclosure having an inlet and an outlet such that the stock flows from the inlet to the outlet.  The headbox also includes a device for selectively controlling the flow of stock ejected through the outlet.  The device includes a profiling roof having an upstream and a downstream end.  The upstream end of the profiling roof is pivotally secured to the enclosure and the downstream end defines a slice lip.  A plurality of adjusters extend from the enclosure to adjacent to the downstream end of the profiling roof for selectively pivoting the profiling roof relative to the enclosure.  The profiling roof has a first and a second face with the first face guiding the flow towards the outlet.  The second face is towards the adjusters and defines a plurality of spaced slots with each slot extending parallel to the flow from the downstream end towards the upstream end of the profiling roof.  The arrangement being such that in use of the apparatus, the adjusters selectively flex the profiling roof normal to the flow for controlling the profile of the ejected stock while maintaining the machine directional stiffness of the profiling roof.

Abstract: An ultrasonic imaging agent is produced by a continuous sonication processing of an aqueous solution of heat-denaturable biocompatible protein. The solution is carefully preheated to a temperature of incipient protein denaturation without forming insolubilized protein. A gaseous fluid, preferably air, is added to the solution. In the sonication, the air-containing solution is foamed, increasing the formation and concentration of microbubbles, and the solution is further heated to insolubilize a portion of the protein, thereby encapsulating the microbubbles and forming particulate microspheres.

Abstract: A mechanism for the removal of incombustible residues from an incineration plant includes a slag shaft, a slag tank positioned under a mouth of the slag shaft and filled with water extending up to the mouth of the shaft. The incombustible residues dropping from the incineration plant furnace grate through the slag shaft collect in the slag tank and are discharged therefrom by a pusher plate via an upwardly sloping discharge path. The pusher plate is in operative connection with two thrust piston drives via two thrust rods and two rocking levers. The joint connecting the thrust rod with the rocking lever is arranged in such a way that it is not immersed in the water bath either in the rear position of the pusher plate or in the discharge position of the pusher plate. Through the direct coupling to the joint, the thrust rod and the rocking lever can operate in the same vertical plane, so that no additional moments are exerted on the rocking shaft. This leads to a longer life for the lint and also to increased operational reliability and easier maintenance.

Title: Electronically controlled prosthetic knee
Inventor: DEFFENBAUGH BRUCE W
IPC: A61F2/60
Filed: 2001-01-22
Granted: 2005-04-14
Abstract: The present invention relates to a variable-torque magnetorheologically actuated prosthetic knee which utilizes a plurality of interspersed and alternating rotors and stators to shear magnetorheological fluid in gaps formed therebetween. Advantageously, by operating in the “shear mode” there is substantially no or negligible fluid pressure buildup or change. Moreover, the multiple MR fluid gaps or flux interfaces desirably allow for the production of a large torque at low speed—eliminating the need for a transmission—and also for a wide dynamic torque range. One embodiment of the invention allows the rotors and/or stators to close the gaps therebetween to create a frictional torque component, thereby forming a “hybrid” braking system which provides a total torque or damping which is a combination of viscous torque and frictional torque.
