Abstract: An offset cantilevered support leg for a height adjustable desk which resists lateral forces is provided. Each support leg is connected to the underside of the desk top at the lateral ends thereof by an L-shaped bracket. A primary support arm provides the cantilevered support for the desk top while a secondary support arm, angularly offset from and generally oriented perpendicularly with respect to the primary support arm, provides support against lateral forces directed against the legs. By orienting each of the respective support arms of the L-shaped bracket with the rear corners of the work surface, the legs provide adequate support against vertical and horizontal loading while maximizing the available space underneath the desk, and thus eliminating the need for a horizontal stretcher between the cantilevered support leg.

Abstract: Non-hazardous organic waste material is introduced into a slagging combustor where it is burned. The burning produces exhaust gases and a slag of molten, inorganic ash which is removed from the combustor. The exhaust gases are treated to cool and dry the gases and to remove a major portion of particulate matter contained therein. A portion of the treated exhaust gases is mixed with a source of concentrated oxygen in a proportion that results in mixed gases having an oxygen concentration of at least 30% by volume. The mixed gases are introduced into the combustor to support the burning of the waste material. Another portion of the treated exhaust gases is further treated to recover the carbon dioxide therefrom.

Abstract: A thawing indication marker for frozen food is disclosed for determining whether or not a frozen food has been thawed. It comprises a tube of an elastic transparent resin, the tube being bent at its center to form two separate containers. One container contains a colored gel-like liquid prepared from an edible starch and food color and the other container contains a gel-like liquid also prepared from an edible starch and food color which is different from the first food color. The marker is used by straightening the bent portion and applying it to frozen food. If the food undergoes thawing, as a result of being subjected to a temperature above the freezing point of water, the gels become less viscous and can intermingle. By virtue of the color difference, one can observe whether or not any intermingling of the two different colored gels has occurred and therefore, whether or not the food stuff has been subjected to non-thawing conditions.

Abstract: A variable valve actuation (VVA) apparatus is disclosed. The VVA apparatus can keep an engine cylinder valve closed. Rotating a camshaft in timed relation with a crankshaft of the engine causes an eccentric crank cam to move a link or crank arm, thereby causing one end of a rocker arm to reciprocate. This causes the other end of the rocker arm to reciprocate. The reciprocating motion of the other end of the rocker arm is transmitted via a link to a valve operating (VO) cam, thereby causing the VO cam to pivot to push a valve lifter for opening the associated cylinder valve. An eccentric circular cam, fixed to a control rod, supports the rocker arm for rotation relative thereto in such a manner that rotation of the control rod causes a pivot center of the rocker arm to move, thereby changing position of the VO cam relative to the valve lifter. The change in the position of the VO cam causes its valve lift diagram to change.

Abstract: A method for bypassing a controlled quantity of airflow around a throttle body of an internal combustion engine of a motor vehicle during periods of sudden deceleration of the vehicle. The method makes use of a bypass valve having an input end in communication with an air inlet of a throttle body of the engine and an outlet in communication with an air inlet of the intake manifold of the engine. When sudden closing of the throttle is sensed, or when the throttle is closed, the bypass valve is opened to a degree sufficient to enable an additional quantity of air to flow therethrough and into the inlet of the intake manifold. The invention significantly reduces the drop in engine rpm experienced during sudden deceleration of the vehicle, to thereby substantially reduce or eliminate powertrain vibration that results during sudden deceleration.

Abstract: The invention is directed to a method and an arrangement for controlling an operating variable of a motor vehicle. A friction-burdened actuator assembly, which influences the operating variable, is actuated via a drive signal. This drive signal is formed on the basis of a desired value of the operating variable. The drive signal is additionally changed in response to a desired change of the operating variable to transfer the actuator assembly out of a steady state condition preferably so as to effect an actual change of the operating variable. In this way, the static friction of the actuator assembly, which is in opposition to the change of the operating variable, is overcome. Furthermore, the drive signal can be additionally changed in the sense of a reduction of the change of the operating variable when the operating variable approaches the desired value thereof.

Abstract: A heat exchanger that is connected to a diesel engine's exhaust system in a manner that forces the hot exhaust gases to pass directly through an internal heat exchange chamber. This is accomplished by placing a heat exchanger unit within the body of the air filter canister which is typically installed externally on a truck. This heat exchanger is then connected at its lower end to the primary exhaust system of the truck by means of section of exhaust tubing and at its upper end to a secondary exhaust pipe. Thus, when the hot exhaust gases enter the heat exchanger within the air cleaner, the exchanger is rapidly heated up which serves to heat the air passing through the filter canister prior to its entering the engine. This heated air not only speeds up the warm up process of the engine but also increases the operating efficiency of cold diesel engine because the burning properties of diesel fuel are enhanced at higher temperatures.
