A way cover section is shaped with a continuous lateral arc by pre-stressing so that its top panel has a radius in its top panel from one side panel of the cover section to the other. A wiper at the leading edge of the cover sections that may also serve as a bumper. The wiper has an elastomeric wiper section at one end and an elastomeric bumper section at the other end, with an intermediate section of a harder and more lubricious material that fits on a rolled over edge of the cover section to which the wiper is attached.

A waste compacting apparatus includes a compactor housing with a vertically reciprocating ram mounted in its upper portion. A waste inlet is provided in the middle portion of the compactor housing for receiving waste, and the received waste is fed into a removable waste receptacle located in the lower portion of the compacting housing. Waste compaction takes place when the vertically reciprocating ram is driven down into the receptacle in the lower portion of the housing. The waste receptacle is horizontally slidable from a first position within the compactor housing, in which compacting takes place, to a second position outside the housing, during which the receptacle is unloaded. A vertically reciprocating sleeve is mounted within the housing, surrounding the ram, and has a waste inlet aperture in its upper portion. The sleeve extends downward from an upper position, in which the housing waste inlet is blocked by the sleeve, to a lower position, in which the waste inlet of the housing and the waste inlet aperture of the sleeve are aligned to permit waste to enter the sleeve and the lower portion of the sleeve extends into the lower portion of the housing within the removable waste receptacle. In this manner the sleeve protects the receptacle as the ram is extended downward to compact the waste within the receptacle. Both the ram and sleeve may be provided with slidably contacting shearing knives, so that any waste trapped between the ram and sleeve will be sheared off and will not jam the compaction apparatus.

A waste disposal system embodies a waste diverter apparatus for receiving waste from a single waste supplying chute and selectably controlling distribution of the waste to a pair of waste outlet chutes. Each of the waste outlet chutes is connected to a waste compactor or other suitable means for waste disposal. The waste diverter apparatus includes a waste diverter housing which has a single waste inlet opening, and a pair of waste outlet openings which connect to the pair of waste outlet chutes. A waste outlet gate is provided for each waste outlet opening, and each gate slides horizontally to open and close its corresponding waste outlet opening. The waste outlet gates are supported in a vee configuration by three parallel horizontal bars; a single lower bar having two slotted tracks to receive the lower edges of both waste outlet gates, and a pair of spaced, horizontal upper support bars, each parallel to the lower bar and each having a single slotted track to receive the upper portion of one waste outlet gate. Each of the waste outlet gates is independently activated by an associated hydraulic driving ram, which is connected to its associated gate by a suitable driving shaft.

A CD or DVD tray made from paperboard is provided. The tray may be made from 100% recycled paperboard and can be 100% recyclable. The design of the tray or holder (used interchangeably throughout) uses the structural geometry of facets, central hole and radial slits to form a hub that achieves the function of securing the CD to the tray. Non-structural paper stock is formed into an effective fastening device whereby the fit of the hub is determined by the geometry of the folded paper. The paper tray of the present invention duplicates the functionality of plastic trays and is compatible with industry auto-loading, while providing the environmental benefits of paper.
摘要:
A low cost, bi-directional manifold air flow sensing device based on sensed temperature differential due to airflow achieves improved sensitivity and frequency response by eliminating the heater element of the conventional sensor topology, and operating the sensor elements at a relatively higher current so that each temperature sensing element heats both itself and the other temperature sensing element. The sensitivity is significantly increased due to the increased current in the sensor elements, and the frequency response is significantly increased due to closer spacing of the sensor elements. With this new topology, the sensor elements are said to be mutually heated. In a particularly advantageous mechanization, the sensing device includes two separate pairs of upstream and downstream sensing elements, and the sensing elements are connected in the four legs of a Wheatstone bridge. The sensitivity is doubled since sensor elements are connected in each of the bridge legs, and performance and cost are improved through the elimination of off-chip bridge components. A simple, low cost, temperature compensation circuit compensates for ambient temperature variations.

A power supply device for providing uninterrupted power for a period of time is disclosed. The power supply device has a controller and a flywheel device. The flywheel device has a housing that contains a flywheel rotor and a motor/generator rotor. The flywheel rotor and the motor/generator rotor are mounted on a common shaft. An active axial magnetic bearing is located to support the shaft for frictionless rotation. The bearing provides support for the shaft, the flywheel rotor and motor/generator rotor. The axial magnetic bearing is attached to the housing and provides, in combination with the motor/generator rotor, a flux path and magnetic field to exert a magnetic force to lift the motor/generator rotor and the shaft on which it is mounted.
