A round-shank bit for a coal cutting machine or the like, having a bit head and a bit shank, wherein the bit head has a bit tip, maintained by a base element in a receptacle of the bit head. Starting at the base element, the bit tip tapers in a direction toward the free end of the bit tip, wherein the base element forms a maximum diameter of the bit tip, and wherein the bit tip has recesses on its outer contour. In order to assure good rotational behavior over the entire length of the operating time, the base element has the recesses on an outer circumference forming the maximum diameter.

An oral care implement including a handle and a head with a tongue cleanser. The tongue cleanser has at least one ridge which is at least as wide as it is high. In one preferred construction, the ridges are shaped so as to define a concave surface facing generally toward the handle. The ridges also preferably include aligned segments from front to back that are oriented at different angular positions.

An athletic shoe, with a sole and a shoe upper, connected thereto, which surrounds the front of the foot, the ankle region and the heel region of the foot. The shoe is able to be collapsed down to a low height for packing, without negatively affecting the ability of the shoe to hold the wearers foot in an optimal manner in use. This ability is achieved the shoe upper being provided with an incision in the heel region, running at least nearly in a direction perpendicular to the sole, whereby the parts of the shoe upper, on both sides of the incision can be folded or turned inwards down toward the sole.

An implant for use in ankle arthroplasty is provided. The implant includes a first member for cooperation with the tibia and a second member for cooperation with the talus. The second member is operably associated with the first member. The implant also includes a third member rigidly removably connectable to the second member. The third member includes a portion of the third member for attachment to the calcaneous. The third member is adapted to provide for a first position in the calcaneous when said third member is in a first relative position with respect to the second member is adapted to provide for a second position in the calcaneous when the third member is in a second relative position with respect to the second member.

An exercise treadmill is disclosed. The treadmill can be constructed with no obstructing front rails, with one or more side rails, and/or with a structural flat or ramped surface at the front allowing the user to exercise with unconstrained motion. The treadmill can further include one or more accommodations to help the user stay safe, remain longitudinally centered, and/or adjust speed with controls built into the treadmill, or automatically based on body position relative to sensors built into the side rails. The treadmill belt may be motor driven, or be user driven and dynamically moderated by resistance. The treadmill configuration can be utilized to provide a virtualized exercise experience for the user.

A lift-type turbine comprising at least three blades at circumferentially spaced positions is supported for rotation about a vertical axis. Each blade has an airfoil shape to generate a torque about the axis responsive to wind across the blades. A support comprising cables under tension is connected between adjacent ones of the blades to extend generally circumferentially about the turbine. Accordingly a minimum number of parts form the structure of the blades while minimizing the drag produced during rotation thereof due to the support members lying in a common circumferential path. The tension of the support members can support the blades in a pre-stressed condition to optimize the shape and performance thereof.

An inventive self-aligning blade joint structure is provided to facilitate assembly and clamping of wind turbine blade sections carried on a transporter. The blade joint structure includes alignment pins on one end bulkhead of a blade body section at the joint and complimentary female bushings on a bulkhead of an adjacent blade body section to permit fine alignment of the joint. The blade joint structure also includes through holes in the end bulkheads for the adjacent blade body sections to permit clamping of the sections in preparation for application of adhesive bonding to the joint. A pair of male scarfed surfaces of spar caps extend from one blade section into the second blade section and engage female scarfed surfaces of spar caps formed in the second blade section and recessed from the joint. An inventive method is provided to utilize the self-aligning blade joint structure for assembly of the blade sections.

Systems and methods for disposing and supporting a solar panel array are disclosed. The embodiments comprise various combinations of cables, support columns, and pod constructions in which to support solar panels. The solar panels can incorporate single or dual tracking capabilities to enhance sunlight capture. The embodiments encourage dual land use in which installation of the systems minimizes disruption of the underlying ground. Supplemental power may be provided by vertical axis windmills integrated with the columns. Special installations of the system can include systems mounted over structures such as parking lots, roads and aqueducts. Simplified support systems with a minimum number of structural elements can be used to create effective support for solar panel arrays of varying size and shapes. These simplified systems minimize material requirements and labor for installation of the systems.

A stent includes a cylindrical frame consisting of a series of helical winds containing a pattern of alternating zigzag bends. The frame may be made of resilient wire or from a piece of laser cut hypo tubing by placing the stent over a notched portion of a pusher catheter member, and retained on the pusher catheter member by a release wire threaded through the pusher catheter member and over the stent. The stent may also be deployed by placing the stent over a pusher catheter member having opposing notched portions, and retaining the stent and pusher catheter member in a delivery catheter, which can be withdrawn when stent reaches the site to be treated to release the stent.

A cellular system comprising at least one moving non-stationary base station for enabling cellular communication between at least two mobile stations in a geographic area that lacks adequate cellular coverage by at least one stationary base station.

The present application describes a coaxial guide coil catheter device to be placed inside of a standard cardiovascular guide catheter for facilitating extra support in the coronary artery when advancing interventional cardiology devices such as balloon catheters and stent delivery systems. This device is passed through the main lumen of a standard guide catheter so that the tip of the coaxial guide coil device is extended past the tip of the guide catheter and into the coronary artery. The proximal portion of the coaxial guide coil will remain within the guide catheter. The device improves the ability of the guide catheter to remain seated in the coronary ostium during interventional procedures.

A litter-free pet waste collection system providing a sanitary, easy to clean and aesthetically pleasing unit for receiving household pet waste without utilizing granular or pelleted litter, comprising a base, a diverting tray having a sloped bottom surface and an aperture therein for draining liquid waste, a perimeter wall section for containing waste, a support tray and grill lined with a permeable, non-absorbent material for supporting the animal in the unit while allowing liquid waste to flow through to the diverting tray, and a removable covered liquid waste receptacle housed in the base and aligned under the diverting tray aperture whereby liquid waste is easily disposed of and odor is effectively contained.
