摘要:
Methods of use of a portable in-bed exercising machine are provided for strengthening and/or strength maintenance of the musculature and ligaments associated with an extremity. The exercise apparatus employs the principles of closed kinetic chain exercise of the extremity in both concentric and eccentric modes and for isometric, isotonic and isokinetic exercise. Each extremity is engaged separately allowing for bilateral, unilateral and reciprocal motion. As exemplified for lower extremities, force is actively applied to the feet with each lower extremity having the force level continuously adjustable from zero force to a force equal to or greater than body-weight The exercise motions and force applications use the same major muscle groups as functional activities such as standing from a chair, climbing stairs walling, jumping and jogging. Vertical support is provided for the lower extremity to stabilize and control the lower extremity motion within safe limits. Back support is provided for the user to exercise in a supine position. Almost any bed may be integrated with the force producing machine to form the exercise apparatus. The methods of use are adaptable to low gravity environments such as space stations, space shuttles, and other space-like environments.

A trading card game (10) includes a first card (212) having only one immovable section (234). The game (10) also includes a second card (314) including a first section (352) and a second section (354). The second section (354) can be slidable relative to the first section (352) so that the second card (314) moves between a first position and a second position. In the first position, a portion of the second section (354) is unexposed to the players. In the second position, the portion of the second section (354) is exposed to the players, and influences the outcome of at least a portion of the game (10).

A fuel nozzle is provided. The fuel nozzle includes a heat shield, a fuel tube and a plurality of support members. The support members are radially interposed between the heat shield and the fuel tube. The support members are preferably cylindrical tubes, thus creating voids or pockets between the heat shield and the fuel tube. The cylindrical tubes are connected to one another at a first end are free at an opposed end. As such, the tubes can move or slide relative to one another. Further, the tubes preferably only contact one another with at most line contacts. The fuel nozzle may also include a tip portion that includes a tip heat shield that extends radially outward from the primary heat shield. The tip heat shield defines a cavity that connects with the central cavity of the heat shield. The fuel tube extends through the tip heat shield.

A power system includes a housing having a base and a handle, a battery; a charge controller, and an inverter. The power system further includes a chimney-like venting system for cooling the power system. The chimney venting system may have at least one opening near said base and at least one opening near said handle.

A modular container for stackably storing and transporting multiple circular saw blades. The container includes multiple storage trays wherein each storage tray is able to hold one or more circular saw blades of varying diameters. The storage trays have graduating annular raised surfaces to hold saw blades securely in place during transport thereby preventing injury to the transporter and protecting the cutting teeth of the circular saw blades from being damaged due to movement within the storage container. Each storage tray horizontally pivots open to allow the user easy access to the circular saw blades stored therein.

This invention makes possible substantially continuous flow of uniformly distributed hydrogen and hydrocarbon liquid across a densely packed catalyst bed to fill substantially the entire volume of a reactor vessel by introducing the fluids as alternate annular rings of gas and liquid (i.e. a mixture of liquid hydrocarbon and a hydrogen-containing gas) at a rate insufficient to levitate or ebullate the catalyst bed. Catalyst are selected by density, shape and size at a design feed rate of liquids and gas to prevent ebullation of the packed bed at the design feed rates. Catalysts are selected by measuring bed expansion, such as in a large pilot plant run, with hydrocarbon, hydrogen, and catalyst at the design pressures and flow velocities. The liquid and gas components of the feed flow into the bed in alternate annular rings across the full area of the bed. At the desired flow rate, such catalyst continually flows in a plug-like manner downwardly through the reactor vessel by introducing fresh catalyst at the top of the catalyst bed by laminarly flowing such catalyst in a liquid stream on a periodic or semicontinuous basis. Catalyst is similarly removed by laminarly flowing catalyst particles in a liquid stream out of the bottom of the catalyst bed. Intake for such flow is out of direct contact with the stream of gas flowing through the bed and the flow path is substantially constant in cross-sectional area and greater in diameter by several times than the diameter of the catalyst particles. The catalyst of this invention produces a plug-flowing substantially packed bed of hydroprocessing catalyst which occupies at least about 75% by volume of the reactor volume.

A parachute assembly includes a canopy, a harness connected to the canopy by lines, the canopy having an apex and a basal perimeter. Envelopes in the canopy defined by a plurality of generally triangular inflatable gussets extend from adjacent the apex to adjacent the basal perimeter and taper outwardly towards the basal perimeter. The assembly includes a source of pressurized gas and flexible conduits connecting the gas source to the gussets. One or more valves for releasing the gas from the source through the conduits to the inflatable envelopes and manually operable valves to release the pressurized gas into the conduits and envelopes to inflate the gussets.
摘要:
A device for the processing of uniquely combined thermally developable, photosensitive layers with illuminating means for imagewise exposing one of the photosensitive layers while it is being heated to development temperature and also exposing with another illuminating means another of the photosensitive layers from the image exposed and developed in the first photosensitive layer, the last exposed layer being developed by the same heating imparted thereto for development of the first exposed layer to obtain an image which can be transferred in the same operation to a receiving medium.
摘要:
A system for controlling an electricity supply to a load comprises at least one battery for storing energy. The system also comprises a controller for determining when to switch between a first mode wherein electricity is supplied to the load from a mains electricity circuit; and a discharging mode wherein electricity is supplied from the battery to the load via the mains electricity circuit. The determining is based on information associated with the electricity supply.
