Abstract: A fiber includes a base having a surface to be impacted by a fluid wave for propelling the fiber forward and a body having a trailing end connected to the base, a leading free end, and a spiral shape causing the fluid wave to rotate the fiber. A locking system causes the fiber to engage and hold at least one other fiber being propelled and rotated by the fluid wave.

Abstract: A flux-focused, shaped permanent magnet includes a body of magnetic material having multiple surface contouring to form a reduced flux side with convex surfaces and an increased flux side with concave surfaces. The surfaces develop high and low resistance external flux paths creating focused asymmetric flux fields. A magnetic unit having the shaped permanent magnet and a magnetic flux attracter or two shaped permanent magnets interconnected by two segmented permanent magnets and a kinetic device having a stationary stator ring, a rotor disc rotating within the stator ring and a multiplicity of the magnetic units on the stator ring and the rotor disc, are also provided.

Abstract: A high-efficiency water heater dip tube includes a wall having orifices formed therein for conducting an outflow of relatively colder water from the dip tube into relatively hotter water in an interior of a water heater. The orifices have a size, number, shape, pattern and location for at least minimizing turbulence, for reducing admixing near the tube, for diluting, equalizing and blending efflux flow and for reducing outflow force and speed. A method for reducing turbulence in water heaters includes providing a dip tube including a wall having orifices formed therein, conducting an outflow of relatively colder water from the dip tube into relatively hotter water in an interior of the water heater, and selecting a size, number, shape, pattern and location of the orifices for at least minimizing turbulence, reducing admixing near the tube, diluting, equalizing and blending efflux flow and reducing outflow force and speed.

Abstract: A biopsy needle has a forward needle opening that can be closed off with a trap door. The trap door is pivotally mounted to a flat top surface inside the needle opening. As the needle is extracted, a forward blade of the trap door cuts into the biopsy tissue and the trap door pivots about a pivot axis extending transversely to a longitudinal direction of the needle. The trap door is configured to match a contour of the top surface and an adjacent curve of the needle opening to maintain the needle substantially open when the trap door is in the open position and to close the forward needle opening when the trap door is in the closed position and the biopsy tissue specimen is entrapped inside the needle.

Abstract: An orthopedic sandal or shoe to be worn intermittently with and to correct the effects of high heel shoe wear, includes a body with upper and lower surfaces. The upper surface provides equalized pressure support without concentration on the heel or balls of the foot and without arch support. A traction system provides first toe traction without foot rotation relative to the upper surface. A foot securing system is disposed at the upper surface. A heel support at the upper surface interacts with the foot securing system to eliminate toe gripping and strain. A descending slope or dome may be provided at the upper surface to support, spread and downwardly deflect the toes to reverse dorsal-flexing. An elevated forefoot angulation may be provided at the upper surface to stretch the plantar fascia and Achilles tendon. A rocker bottom may be provided only under the toe area of the lower surface.

Abstract: A method for producing a hammer lock includes the steps of forming a hammer lock base having a threaded recess formed therein, a thumb grip and a hammer blocking rail for blocking an actuation of a hammer, forming a threaded shaft having a head for receiving a key for turning the threaded shaft and threading the threaded shaft into the threaded recess. The thread shaft is capable of being moved out of the threaded recess and extending below a surface of the hammer lock base. A method for engaging a hammer lock and a hammer lock to be inserted in a gun are also provided.

Abstract: A motorcycle towing device includes a substantially vertical member and a substantially horizontal member being interconnected for supporting a motorcycle wheel. A support column is pivotably and releasably mounted on at least one of the members, such as with a removable hinge pin passing through holes in the support column and in brackets on the support column. A draw bar is connected to the support column for insertion into a receiver mounted on a vehicle and at least one shim is disposed between the draw bar and the receiver.

Abstract: A firearm suppressor includes a housing to be mounted to a firearm. The housing defines a lumen therein for receiving gases from the firearm. At least one stripper member is disposed in the lumen for engaging and deflecting the gases. At least one one-way flow element is disposed downstream of the at least one stripper member in gas flow direction for permitting a one-way flow of the gases. At least one decompression chamber is disposed downstream of the at least one one-way flow element for reducing energy in the gases. At least one vent valve is disposed downstream of the at least one decompression chamber for expelling the gases into the atmosphere. A mounting system and a mounting method are also provided.
