Abstract: The bark stripper blade has at least one sharp edge (6) formed by leading (7) and trailing (8) surfaces on a base plate (8). The leading face is reinforced with an anti-abrasion layer (16) which is harder than the material of the base plate and has a regular thickness of between about 0.2 and 1 mm. The anti-abrasion layer is made from a mixture of tungsten carbine granules with a grain size of 40 - 160 microns, bound in a metal alloy of Ni/Cr/B/Si with a hardness of between 40 and 60 HRC. It is applied by powder in a laser beam, which partially melts the material and ensures its adhesion to the base plate. The base plate is made from steel.

Abstract: A portable net (10) has an erected configuration for practicing golf or the like by stopping the flight of a golf ball (22) and returning it to a selected location and a folded configuration for storage or transport.  The portable net (10) has an elastic frame (12) that forms a base (11) and a net support section (13). A net (18) is connected to the net support section (13) of the frame (12) so that the net (18) is extended away from the base (11) in the erected configuration. The net (18) is arranged to stop the flight of a golf ball (22) that is incident thereon. A fabric (26) is connected between the net (18) and the base (11) so that projectile that has impinged upon the net (18) falls to the fabric (26) and then rolls to the front portion of the portable net (10).  The frame is configured such that a person may put the frame (12) into a folded configuration by deforming the first and second frame members (14, 16) into a plurality of generally concentric rings. A retainer such as a strap (134) is provided for selectively retaining the frame (12) in the folded configuration. The frame (12) is formed such that elastic forces in the frame spontaneously move the frame (12) to the erected configuration when the retainer (134) is not engaged to retain the frame (12) in the storage configuration.

Title: Steering, tensing and driving a revolving casting belt using an exit-pulley drum for achieving all three functions
Inventor: DYKES CHARLES D
IPC: B22D11/06
Filed: 1998-02-27
Granted: 2011-02-15
Abstract: Steering, tensioning and driving a revolving metallic casting belt in continuous casting machines wherein the belt travels along a generally straight casting plane P. Two two-axis robotic mechanisms are positioned at opposite ends of an exit-pulley drum, each including a "floating" housing carrying a bearing rotatably supporting a journal at the respective drum end. A drive connected to one of the journals rotates the drum for revolving the belt. The robotic mechanisms adjustably position opposite ends of a rotating drum in X--X plane parallel with plane P for tensioning the belt and in Y--Y plane perpendicular to plane P for steering the revolving belt. These robotic mechanisms are controlled to operate in any of several modes: (1) "Walking-tilt" steering keeps the belt much closer to an exiting product than prior art, the belt being flatter and in better contact with the product for improving casting speed and quality. Diode (2) provides a "virtual squaring shaft" causing a drum to simulate being constrained by a rigid mechanical squaring shaft for synchronizing downstream movements of both drum ends for regularizing tension fully across a"cylindrical" casting belt. In modes (3), (4) and (5) the rigidity of the virtual squaring shaft may be "softened," or re-zeroed or eliminated, to accommodate small "frustro-conical" errors in belt manufacture.  Moreover, even a small error in built-in length dimensions of a belt carriage may effectively be canceled by mode adjustments which effectively "twist" the virtual squaring shaft.

Abstract: The present invention is directed to a novel adjustable diameter hair curler which is extremely lightweight, portable, and suitable for travel. The novel adjustable curler includes a sheet (10) of a flexible material such as a plastic or fabric or backing material. The sheet (10) has a first planar side (14) and a second planar side (18) opposite said first planar side. Attached to the first side (14) of the sheet (10) is an array of hook-type elements (12) from a hook and loop type fastening system such as VELCRO® brand hook and loop fasteners available from VELCRO Industries of Manchester, New Hampshire. The hook-type elements (12) are generally arrayed over the bulk of the first side (14). Attached to at least a portion of the second side (18) are loop-type fasteners (16) or a material which will stick to the hook-type fasteners (12). By rolling the sheet (10) to form a cylinder so that a portion of the sheet overlaps another portion of the sheet, the hook and loop fasteners (14, 16) may interact to hold the cylinder's shape with relative ease and complete adjustability of cylinder diameter. Lock-in of the shape may be accomplished easily with a single hand.  For storage, the sheets (10) may be completely flattened for storage or transport in a very minimal volume. ®

Title: Method for unlicensed band port to autonomously determine interference threshold and power level
Inventor: NOERPEL ANTHONY R
IPC: H04B1/04
Filed: 1996-03-27
Granted: 2001-08-07
Abstract: Radio ports (RPs) in an unlicensed personal communications system adaptively, autonomously set their interference threshold and/or transmission power levels. This may be done by the RP measuring the signal level on each of the available channels and then setting the interference threshold and/or power level according to these measurements. In a preferred method (600), the interference threshold is determined by measuring the signal level on each channel (604), ranking the channels in order of measured signal level, and using these rankings to determined the threshold (606). The transmission power level may be set with reference to the adaptive interference threshold level. This level is determined by using the system and FCC power limitations and current conditions to provide a satisfactory transmission level.

Title: Controlled detachment stents
Inventor: RICHTER JACOB
IPC: A61F2/82
Filed: 1999-09-03
Granted: 2009-11-24
Abstract: A stent is provided with specific "designated detachment" points or zones, such that after the stent is deployed, the stress applied on the stent will cause the stent to detach at these designated detachment points or zones. When the detachment occurs completely around the circumference of the stent, the stent separates into stent segments, each able to move with the vessel independently of the other stent segments. The components at the designated detachment zones may have a cross-sectional area sufficiently low so that the components will detach under the stress placed on the stent after implantation. Alternatively or additionally, the components at the designated detachment zones may be made of a material that is sufficiently weaker so that the components will detach under the stress placed on the stent after implantation. The stent may have a lower number of components at the designated detachment zones than in the stent segments.
