Abstract: A magnetic holder for holding a non-magnetic sheet against a magnetically attractive surface contains a body having a first end and a second end, an upper surface and a lower surface. The body is formed from a first material having a first co-efficient of friction. The lower surface has a first portion and a second portion. The first portion is joined to the second portion at a fulcrum line that defines an obtuse angle between the first portion and the second portion for preventing the first and second portions from engaging the magnetically attractive surface simultaneously. A magnet member is disposed on the second portion for magnetically coupling the holder to the magnetically attractive surface. A first gripping member is disposed on the second portion for frictionally gripping the non-magnetic sheet.

Abstract: A carbon fiber bicycle crank includes an axle lug, having a portion for receiving a crank axle. A foam core is coupled to the axle lug during a first molding process. A pedal engaging lug is coupled to the foam core after the completion of the first molding process, and a carbon fiber composite material exoskeleton is coupled to and disposed exteriorly of the axle lug, foam core and pedal lug.

Abstract: An anesthesia delivery device can be coupled to a ventilation system. The device includes an inspiratory gas line having a machine end and a patient end. The machine end can be fluidly coupled to the ventilation system, and the patient end can be received within the naris of the patient. A face mask having a dome portion can cover the patient's nose without covering the patient's mouth and defines an inside air space between the patient's nose and the dome portion, and an outside air space exterior of the dome portion. A vent allows gas to pass between the inside and outside air spaces. An exhaust port can be fluidly coupled to the exhaust gas output. The exhaust port and vent can cooperatively exert a negative pressure on the outside air space for preventing inspiratory gas from entering the outside air space.

Abstract: In accordance with the present invention a hobbyist-useable apparatus and method for fabricating decoratively shaped writing instruments is disclosed. The apparatus for fabricating decoratively shaped writing instruments having a casing includes a heater unit and a shaper unit. The heater unit includes a heat source, and a heating compartment having an opening for inserting and removing the writing instrument casing. The heat source provides heat to the heating compartment. The shaper unit includes a platform having an elongated slot, an exterior mold assembly attachable to the platform and moveable in the elongated slot; an exterior shaping surface coupled to the exterior mold assembly; and an interior mold insert having an interior shaping surface. The interior mold insert is attachable to the platform such that the movement of the exterior mold assembly in the elongated slot moves the exterior shaping surface towards and away from the interior shaping surface.

Abstract: A non-tracheal ventilation tube includes a multi-lumen tube shaft having a proximal end and a distal end, a proximal cuff and a distal cuff. The multi-lumen tube shaft is separated into a ventilation channel extending from a proximal ventilation opening to a distal ventilation opening, a suction channel extending from a proximal suction opening to a distal suction opening, and an inflation channel. The proximal cuff is attached to the tube shaft and is connected to the inflation channel for inflation and deflation. The distal cuff is attached to the tube shaft on the distal side of the proximal cuff and is connected to the inflation channel for inflation and deflation. The proximal suction opening and the proximal ventilation opening are located on the proximal side of the proximal cuff. The distal suction opening is located on the distal side of the distal cuff. The distal ventilation opening is located between the proximal cuff and the distal cuff.

Abstract: A unilimb breathing circuit has a proximal end coupling member, a distal end coupling member, an expiratory tube extending between the proximal and distal end coupling members, and an inspiratory tube extending between the proximal and distal end coupling members. The expiratory tube is a corrugated expiratory tube that is expandable between a fully compressed rest position, and a fully expanded rest position, and has a plurality of intermediate rest positions. At the plurality of intermediate rest positions, the expiratory tube is capable of maintaining its rest length without the exertion of an external force. The inspiratory tube is a corrugated inspiratory tube having a length that is variable between a fully compressed rest position and a fully expanded rest position, and includes a plurality of intermediate rest positions between the fully expanded rest position and the fully compressed rest position.

Abstract: A valve is provided for use in a domestic water re-circulation system The valve has a unitary body member that includes an upstream end and an upstream portion disposed adjacent to the upstream end. The body member also includes a downstream end and a downstream portion disposed adjacent to the downstream end; and a middle portion disposed between the upstream portion and the downstream portion. A radially outwardly facing outer wall and a radially upwardly facing inner wall exist. The radially inner facing wall defines an axially extending passageway extending between the upstream end and the downstream end, and through the upstream portion, middle portion and downstream portion of the body. The axially extending passageway includes a corresponding upstream end, a downstream end, an upstream portion, a middle portion and a downstream portion. The body further includes a radially extending controller port and a radially extending flow limiter port in fluid communication with the axially extending passageway.

Abstract: A bicycle wheel includes a tire engaging portion located at the outward perimeter of the wheel, an inner portion located radially inward from the tire engaging portion A pair of air engaging side surfaces extend radially between the inner portion and the tire engaging portion forming the sides of the wheel. The air engaging side surfaces contain a plurality of surface features designed to create a turbulent boundary layer when the wheel travels through air to reduce aerodynamic drag on the wheel.

Abstract: A fiber resin plastic (FRP) based bicycle rim includes an FRP body and a metal tire receiving ring. The FRP body has first and second side surfaces, an annular outer edge surface, and an annular inner edge surface. The annular inner edge surface includes at least two spoke receiving ports for receiving and supportively coupling at least two spokes to the FRP body. The metal tire receiving ring is coupled to the FRP body and is disposed radially outwardly of the FRP body. The tire receiving ring includes first and second, generally parallel continuous braking surfaces.

Abstract: According to the present invention, a vehicle monitoring and maintenance device capable of being connected to a diagnostic port of a vehicle is provided. The monitoring and maintenance device comprises a hand holdable, data acquisition and transfer device. The data acquisition and transfer device includes a first data link connectable to a diagnostic port of a vehicle for retrieving diagnostic data from the vehicle; and a second data link connectable to a global computer network communicable device. The data acquisition and transfer device also includes a processor and memory unit capable of retrieving unprocessed diagnostic data containing error codes from the vehicle via the first data link, storing unprocessed diagnostic data for a limited time, and transferring the unprocessed data to the global computer network communicable device, to the second data link.
