Abstract: An eye wear assembly 10 is provided which includes a film-like, resilient collapsible lens 20 that wraps about the eyes of the wearer W from temple T to temple T. The lens 20 is partially held in place by its left and right wings 30 which include respective left and right temple pads 40. The lens 20 is offset from the face of the wearer W by horizontal pads 60 which increase the wearer's W comfort and provide circulation via two primary vents 70 to allow perspiration to dissipate from the enclosure created between the lens 20 and the wearer's W face. A nose cutout region 90, conforming to the general shape of a typical user's nose N, is provided at the midpoint of the lens 20 at its bottom edge 28. A nose saddle 100, made of soft, resilient foam or rubber-type material, is attached adjacent the nose cutout region 90 on the rear concave surface 24 of the lens 20. The nose saddle 100 conforms to the shape of the nose N of the wearer W.

Abstract: A low or no pollution engine is provided for delivering power for vehicles or other power applications. The engine has an air inlet which collects air from a surrounding environment. At least a portion of the nitrogen in the air is removed using a technique such as liquefaction, pressure swing adsorption or membrane based air separation. The remaining air is primarily oxygen, which is then compressed and routed to a gas generator. The gas generator has an igniter and inputs for the high pressure oxygen and a high pressure hydrogen containing fuel, such as hydrogen or methane. The fuel and oxygen are combusted within the gas generator, forming water and carbon dioxide with carbon containing fuels. Water is also delivered into the gas generator to control a temperature of the combustion products. The combustion products are then expanded through a power generating device, such as a turbine or piston expander to deliver output power for operation of a vehicle or other power uses.

The system 10 includes two support lines or straps 16, 18. Each line 16, 18 has coupling points spaced from each other which removably attach to one of the harnesses 12, 14. The lines 16, 18 preferably link together at cross-over point 26 and then extend back to the same harness 12, 14 that the line 16, 18 first extends from the system 10 includes adjustability providing structures and accessories for optimal use to enhance the basic system 10.

Abstract: A device is provided for cleaning of elongate flexible hoses. The device has a smooth radiused low friction entry fairlead that allows the soiled hose to be readily pulled along a straight line path through the cleaner. After entry, the surface of the hose passes through a set of pliant wiping flaps that closely engage the full circumference of the hose, wiping dirt and debris from its surface as it enters the active cleaning region. In the cleaning region, multi-stream jets of high pressure water blast and scour the moving hose's surface, and the hose exits through a second set of pliant wiping flaps that wipe any adherent water from the hose surface. The active cleaning region, filled with water spray, is maintained at a negative pressure by means of an associated suction system which also sucks out the dirty water and debris. The pliant wiping flaps act as partial pneumatic seals, allowing maintenance of the negative pressure in the cleaning region.

Abstract: A method and apparatus for brewing tea is set forth which utilizes heated water from a boiler 7 of an espresso machine 10. A porta-filter 20 having a brewing chamber 40 therein is attachable to a group head 12 of the espresso machine 10. A drain 38 from the brewing chamber 40 leads to an outlet tube 100. An outlet valve 120 restricts outflow from the brewing chamber to a rate less than inflow of heated water from the boiler 7. This facilitates infusion of the heated water with soluble flavor particles from a brewable substance such as tea leaves T before the heated water is discharged from the brewing chamber 40. The brewing chamber 40 is provided at an enhanced pressure relative to atmospheric pressure to enhance the brewing process within the brewing chamber 40.

Abstract: A disclosed walker is a three sided framework allowing quick connect/disconnect to the frame of a conventional standard wheelchair. The walker is formed with a front and two side assemblies pivotally linked to the front assembly. When the walker is not connected to a wheelchair, the side assemblies and front assemblies pivot and collapse into a “z” pattern forming a flat, compact package. For connection to a wheelchair, the sides assemblies unfold perpendicularly to the front assembly, and are locked into place by a horizontal crossbar. U-shaped securing clips located at the rear ends of the walker's side assemblies, drop over and straddle horizontal frame members of the wheelchair tightly grasping the wheelchair's frame members. The stability of the walker/wheelchair combination is enhanced by outward bends of the front vertical sections of the walker which terminate in swivel caster supports.

Abstract: Deck joist flashing 10 is provided which includes a top wall 20 extending between lateral edges 22 spaced apart by a width similar to a width of a joist J to be protected from coming into contact with water. Side walls 30 extend down from the lateral edges 22 of the top wall 20. Bottom edges 34 of each side wall 30 include a beveled wall 40 extending therefrom. Each beveled wall 40 extends diagonally away from the bottom edges 34 of the side wall 30 to a tip 44. The tips 44 of the two beveled walls 40 are spaced further from each other than the lateral edges 22 of the top wall 20 so that the tips 44 are spaced away from sides of the joist J by the flashing 10. In this way, water is directed away from surfaces of the joist J to preserve the joist J from deterioration associated with contact with water.

Abstract: A nozzle is provided which includes a nozzle body having a proximal end and an insertion end and defining an inlet orifice at the proximal end thereof and an outlet orifice at the insertion end thereof. The nozzle body is adapted to be attached at the proximal end thereof to an opening of a container and to be inserted at the insertion end thereof into an opening of a receiving vessel for dispensing a first fluid from the container into the receiving vessel from the inlet orifice to the outlet orifice thereof. The nozzle further includes a venting device connected to the nozzle body and defining a vent discharge opening for venting a second fluid from the receiving vessel into the container through the vent discharge opening such that the second fluid is vented through the vent discharge opening of the venting device without traversing the first fluid in the container substantially during an entire time for a dispensing of the first fluid from the container into the receiving vessel.

At least a portion of the nitrogen in the air is removed using a technique such as liquefaction, pressure swing adsorption or membrane based air separation. The remaining gas is primarily oxygen, which is then compressed and routed to a gas generator. The gas generator has an igniter and inputs for the high pressure oxygen and a high pressure hydrogen-containing fuel, such as hydrogen, methane or a light alcohol. The fuel and oxygen are combusted within the gas generator, forming water and carbon dioxide with carbon containing fuels. Water is also delivered into the gas generator to control the temperature of the combustion products. The combustion products are then expanded through a power generating device, such as a turbine or piston expander to deliver output power for operation of a vehicle or other power uses.

Abstract: An implant assembly 10 is provided for surgical implantation into an intervertebral space S, such as for stabilization of vertebrae V adjacent the intervertebral space S during a spinal fusion procedure. The implant assembly 10 includes a primary segment 20 separate from a secondary segment 60. These segments 20, 60 are elongate and of sufficiently small cross-section that they can be implanted posteriorly in a minimally invasive manner. The segments 20, 60 preferably have a rectangular cross-section so that they can be inserted on a side into the intervertebral space S and then rotated into a maximum height orientation to widen the intervertebral space S. The segments 20, 60 interlock together at an intersection there between. The primary segment 20 preferably includes a tunnel 30 and the secondary segment 60 preferably includes a neck 70 with the tunnel 30 and neck 70 sized complementally so that the segments 20, 60 stabilize each other where they intersect with the neck 70 within the tunnel 30.

A second embodiment of the ladder has a primary weight-bearing strap with loops projecting from one side, this second embodiment being adapted to being folded in half for hoisting heavier loads.

Abstract: A system is provided for controlling a rate at which a treatment fluid is introduced into a main stream to be treated so that a selected characteristic of the main stream matches a set point for the selected characteristic. A pilot stream is diverted from the main stream. The pilot stream is treated with a known amount of the treatment fluid and is analyzed to determine if the selected characteristic matches the set point for the selected characteristic. If the set point for the selected characteristic is matched in the pilot stream, a related amount of treatment fluid is introduced into the main stream. If analysis of the pilot stream indicates that the level of the selected characteristic is above or below the set point, the rate at which the treatment fluid is injected into the pilot stream and the main stream is appropriately adjusted to cause the selected characteristic in the pilot stream and the main stream to more closely match the set point for the selected characteristic.
