Abstract: An exercise apparatus is provided for enabling reciprocating motion of the user's legs or feet while the user remains generally stationary. The apparatus includes a stationary frame, a first longitudinal rail supported, at least partially, by the frame, and a second longitudinal rail also supported, at least partially, by the frame and in generally parallel relation with the first rail. The apparatus further includes a first foot carriage assembly movably engageable along the first rail, a second foot carriage assembly movably engageable along the second rail, and an inertia drive assembly disposed proximate the first and second rails. The inertia drive assembly includes a first continuous belt that is engageable with the first carriage assembly such that movable operation of the first carriage assembly drives the inertia drive assembly, and a second continuous belt engageable with the second carriage assembly such that movable operation of the second carriage assembly also drives the inertia drive assembly.

Abstract: Low volume desiccant dehumidifiers, such as dehumidifiers used for the processing of resin pellets, which provide high dehumidification performance, simplified mechanical arrangement and high reliability in a desiccant dryer optimally suited for low volume applications.

Abstract: Light apparatus includes a translucent housing with a light source disposed within the housing, and a switch extends to the outside of the housing for actuating the light. The light is battery powered, and preferably blinds to provide an intermittent flashing light for alerting persons as to the whereabouts of the user of the lamp. A hook, snap, or the like may be used to secure the light apparatus to a pet's collar.

Abstract: Coffee filter selector apparatus includes a housing having a continuous length of adhesive material for contacting a coffee filter and for removing the contacted coffee filter from a stack of nested coffee filters. The adhesive material is manually wound from a supply reel over an idler wheel, which extends out of the housing and onto a takeup reel. The takeup reel includes outer peripheral notches for a ratcheting system and for allowing a predetermined linear length of adhesive to be advanced from the supply reel onto the takeup reel.

Abstract: Sun tea adapter apparatus includes a relatively long cylinder for holding tea bags and having mesh sides and bottom and adapted to be inserted into a plastic carton, such as one gallon plastic milk cartons, to allow the plastic carton to be used for making sun tea. The adapter includes a top portion above the mesh cylinder, which substantially duplicates the top of the milk carton to enable the milk carton cap to be placed onto the top of the adapter. A second embodiment utilizes a wider mouthed plastic jar which may be specifically designed for the making of sun tea.

Abstract: Electrical commutator and brush apparatus for a bicycle lighting system includes a dielectric disc having a conductive layer secured thereto and adapted to be secured to the spokes of a bicycle. Electrical contact with the commutator disc to supply electrical power is made by a spring contact brush secured to the axle of the bicycle wheel. Electrical power is taken from the disc by electrical connectors making contact with integral elements on the outer periphery of the disc.

Abstract: A three-dimensional network of rigid, porous hollow filament of inorganic material is provided which has high flux capability in treating fluid for separation purposes. The network is made by coating a continuous combustible core with a paste of the inorganic material, fabricating the resultant coated core into the network, followed by firing the coated core to burn off the core and sinter the coating to rigid porous hollow filament.

Abstract: Signal lights secured to front and rear bicycle wheels are connected to the frame of the bicycle for one electrical conductor and to a conductive plate secured to a nonconductive disc which is in turn secured to a wheel. A brush makes electrical contact with the conductive plate, and a conductor extends from the brush to a source of electrical power.

Abstract: A mouthpiece regulator for an underwater breathing apparatus utilizes a unitary valve member to perform both inhalation pressure sensing and inlet valve functions. The valve member includes a hollow stem that projects into an inlet chamber in the regulator housing. The stem end cooperates with a valve seat to function as an inlet valve. The valve member also has a wide flange at the other end of the stem. The flange divides the regulator interior chamber into two regions, one communicating with the mouthpiece, the other communicating via ports with the ambient environment. During inhalation the environmental air or water pressure exerted on the flange causes the inlet valve to open, supplying air to the mouthpiece via the hollow stem. At the end of inhalation, increased mouthpiece pressure and a bias spring together cause the unitary valve member to close the inlet valve. Exhaled gases are expelled via a flap valve covering exhaust openings through the flange.
