Abstract: The present invention provides improved elevator door hatches. The elevator door hatches drop open into the elevator cab and slide at a desirable angle just underneath the elevator cab ceiling, without extending too far or too low into the interior cab space. The elevator door hatches are able to accommodate light fixtures and cabling installed into the elevator door hatches without disconnecting when the door hatches are slid underneath the elevator cab ceiling in the open position. The door hatch also allows for the drop ceiling to be mounted closer to the canopy, which increases the usable height of the elevator cab.

Abstract: A bedding insecticide composition for safely exterminating bed bugs is provided. The bedding insecticide composition includes vinegar, liquid dish soap, rubbing alcohol, peppermint extract, rosemary oil, geranium oil, and ground arbol chili seeds. In a preferred embodiment, the bedding insecticide composition is placed within a spray bottle, wherein the composition is applied to a surface containing a bed bug infestation. Once applied, the insecticide composition effectively rids the surface of any bed bugs. The bedding insecticide composition includes environmentally friendly ingredients allowing the composition to be safely used within a home. Alternatively, the bedding insecticide composition may be used on vegetation for exterminating parasitic insects.

Abstract: A dental hygiene device includes a toothbrush and a dental floss dispenser. The dental floss is stored in the handle of the dental hygiene device and is wound without a spool to decrease the diameter of the handle and allow the handle to fit within a conventional toothbrush holder. The dental hygiene device can also be used to aid in flossing, eliminating the need to use insert two fingers into a user's mouth in order to floss. After flossing, the floss can be severed by using a floss cutter disposed on the handle of the device.

Abstract: The invention relates to an apparatus for continuous digestion of wood chip comprising an upright generally cylindrical vessel having a top end and a bottom end. The top end of the cylindrical vessel is adapted to receive wood chips mixed with a cooking liquor to be treated therein. A first conduit is integrally attached at a first location positioned between the top and bottom ends of the vessel for selectively extracting a first quantity of cooking liquor from the vessel. The first location is positioned upstream of a second location within the vessel where the cooking liquor being at substantially full cooking temperature. A second conduit is integrally attached at a third location positioned downstream from the first and second locations of the vessel.

Abstract: One aspect of this invention relates to a method and digester for reducing the deposition of calcium-based scale in a wood chip digester including extraction from the digester of first and second quantities of cooking liquor having respective first and second calcium concentrations, treating the extracted cooking liquors to produce a cooking liquor having a calcium concentration less that the calcium concentration of the either of the first and second extracted cooking liquors, and, reintroducing the treated cooking liquor to the digester. Another aspect of this invention relates to a method and digester in which through put through the digester is increased by the continuous addition of process liquor into the digester preferably at an upper region of the digester.

Abstract: A level sensor and fuel pump assembly insertable through an access hole of a fuel tank so that an elongated fuel pump is disposed substantially completely within the fuel tank, and so that a flange of the assembly covers the hole and is engaged sealably to the wall of the fuel tank. The fuel level sensor has an arm which projects generally laterally when in a biased operating position from the elongated fuel pump to a float at a distal end. During insertion of the fully pre-assembled fuel sensor and pump assembly through the access hole of the fuel tank, the fuel level sensor is pivoted from the biased operating position to a collapsed position by an external force thus pivoting the fuel level sensor generally parallel, and closely orientated, to the fuel pump. This temporary orientation permits insertion of the fuel pump assembly through the relatively small access hole of the tank.

Abstract: An electric fuel pump module includes a fuel pump driven by an electric motor. The motor has an armature provided with a commutator having a flat face. Brushes engage the flat face of the commutator to supply current to the armature. A groove in the flat face of the commutator provides relief preventing fuel from becoming trapped between the brush and the commutator face. The groove extends in a circular loop around the axis of rotation of the armature and may be centered on or laterally offset from the axis of rotation.

Abstract: A bypass system for a diesel engine having a turbocharger, a bypass conduit, a valve and a controller which cooperate to bypass a portion of the combustion air compressed by the turbocharger bypassed to a turbine portion of the turbocharger or to the atmosphere, a controller containing maps based on empirical fixed point data specific to the engine, turbocharger and bypass system responds to signals indicative of changes in atmospheric pressure, inlet manifold pressure and engine speed to control the valve and prevent the turbocharger from surging.

Abstract: A fuel filter for the inlet of a fuel pump having upper and lower wall portions each constructed of a material with a plurality of openings. The lower wall portion has a greater total thickness and/or a smaller average opening size than the upper wall portion to provide more effective filtration of the fuel drawn into the fuel pump through the lower wall of the filter. The filter also causes a greater resistance to fuel flow through the lower wall thereby increasing the rate of fuel drawn through the upper wall of the filter.

Abstract: A centrifugal fuel pump with a baffle disposed between a fuel inlet and an impeller of the pump. The baffle overlies the inlet opening and substantially prevents the impeller from producing a backflow of fuel through the inlet. The baffle also directs incoming fuel into a generally circumferential flow into the channel of the pump through which fuel is moved and its pressure increased by the rotating impeller. This improves the efficiency and maximum capacity of the pump.
