Title: Ultrasonic medical device operating in a transverse mode
Inventor: RABINER ROBERT A
IPC: A61B17/50
Filed: 2000-09-29
Granted: 2004-08-26
Abstract: An ultrasonic medical device comprises an ultrasonic vibration generator that generates vibration along its longitudinal axis. The ultrasonic vibration is transmitted through an ultrasonic coupler and a series of transformer sections that amplify the ultrasonic vibration. A flexible member is coupled to the distal end of the transformer sections, and is thus supplied with a longitudinal vibration at its base by the transformer sections. The flexible member is designed so that it converts the longitudinal vibration into a standing wave that runs along the length of the flexible member. The standing wave produces a series of nodes and anti-nodes along the length of the flexible member. Each of the anti-nodes produces cavitation in fluids in contact with the probe. The cavitation of the fluids causes destruction of adjacent tissue. In this manner, the entire length of the flexible member becomes a working surface that may be utilized for destroying tissue.

Abstract: A banding machine provides for a controlled intermittent flow of a tubular web or sleeve of thin plastic material from a storage reel, over a tensioning arm and guiding rollers onto a group of machine elements which first open the tube somewhat, stop the flow of material, slice the tube transversely, and pass the cut segment of web over a floating mandrel to form it into the shape of a container positioned below it, while continuing the flow of tubing from the reel down onto the same group of elements to form the next band.  The open segment of band is now placed over the container automatically to complete the banding operation.

Title: Method for batch cleaving semiconductor wafers and for coating the cleaved facets
Inventor: BROOM RONALD F
IPC: H01L21/301
Filed: 1991-05-24
Granted: 1993-09-21
Abstract: ABSTRACT   A method for cleaving semiconductor wafers, or segments thereof, which comprises placing the wafer (11), provided with scribe lines (15) defining the planes where cleaving is to take place, inbetween a pair of flexible transport bands (12, 13) and guiding it around a curved, large radius surface (21) therebyapplying a bending moment. With a moment of sufficient magnitude, individual bars (22) are broken off the wafer as this is advanced, the bars having front- and rear-end facets. On cleaving, each bar, while still pressed against the curved surface, is automatically separated whereby mutual damage of the facets of neighbouring bars is prevented. For further handling, e.g. for the transport of the bars to an evaporation station for passivation layer deposition, provisions are made to keep the bars separated. Cleaving and the subsequent passivation coating can be carried out in-situ in a vacuum system to prevent facet contamination prior to applying the passivation.

Granted: 1994-11-08
Abstract: ABSTRACT    A pedal mechanism for a human propulsion vehicle such as a bicycle wherein the length of each of the pedal arm is increased during the power stroke and decreased during the return stroke of the rotation cycle. It comprises a pair of sun gears rigidly attached to the frame of the vehicle, each meshed to an adjacent planetary gear of identical diameter. A lever,  radially projecting from each of the planetary gears, generate the alternative movement of the corresponding pedal arm. The levers also change the angular orientation of the pedal arms by moving them toward the power stroke zone, forcing the pedals arm to stay as long as possible in power stroke, thus giving the pedal mechanism no dead point. This pedal mechanism is very suitable for bicycle, especially mountain bicycles and racing bicycles where high power and efficiency are crucial.

Granted: 2003-11-11
Abstract: To repair or join sections of a metal article, matching metal powder is sintered in the solid state to form a porous structure in the joint. A layer of matching powder, modified to incorporate melting point depressants such as boron and silicon is subse-quently added to the surface of the sintered region.

Title: Multiple implement hitch and steerable wheel assembly therefor
Inventor: SNYDER MICHAEL DUANE
IPC: A01B59/04
Filed: 1993-03-31
Granted: 1996-06-04
Abstract: Hitch structure for connecting first and second implements for operation side-by-side in the field, and one directly behind the other for transport.  A freely rockable swing hitch has a forward end connected to one side of the first implement frame for pivoting less than 180° about an upright axis located inwardly from the side.  A latch on the swing hitch mates with a frame-mounted rear bracket to secure the hitch in the transport position.  The same latch secures the swing hitch to a bracket on the forward towing hitch when the swing hitch and towing hitch are in the field-working position.  A sliding tubular member and two-position latch selectively secure the towing hitch in either a central transport position or an offset field-working position.  Both latches have release levers for changing from one position to the other, and the latches automatically lock in the new position when the desired positon is attained.  A steering mechanism located on the caster wheel assembly of the trailing implement and operable from the tractor cab guides the second implement as the swing hitch pivots during conversions.
