摘要:
A priority hydraulic flow diverter control assembly for a refuse collection vehicle hydraulic system provides proper and efficient flow in an auxiliary hydraulic circuit regardless of the primary flow so that refuse cart lifters and the refuse cart operate safely and efficiently. A pressure sequence valve enables the system to operate in the most efficient manner with respect to pressure drop and flow loss. The pressure sequence valve diverts hydraulic fluid flow from the refuse cart lifter circuit into the downstream main hydraulic system when downstream back pressure is low. When back pressure is high, the pressure sequence valve diverts hydraulic fluid flow from the refuse cart lifter circuit into the system tank. This allows all hydraulic operated equipment to operate that their intended speed at high and low system back pressures. A differential pressure sensing valve and flow regulating valves provide a precision flow. Harmful and undesirable vibrations and noise associated with pulses in hydraulic system pressure are reduced using a control orifice located in the valve body. A relief valve ensures that the diverter control assembly is compatible with other manufacturer's products.

The present invention includes a pass transistor that limits current drawn from a circuit without using a series resistor and while drawing minimal current from an external supply. A current mirror of the output current is formed and compared to a reference current. When the output current increases, the mirror current increases proportionally, and when a threshold is crossed, the pass transistor is turned off. The pass transistor is biased from a charge pump that provides a voltage, a current from which a current mirror is drawn that controls the pass transistor.

Disclosed is a method for dislodging a mold from a casting formed within the mold. The mold may be removed from the casting by scoring the mold and applying a force sufficient to cause the mold to fracture and break into pieces. Additionally, the mold may be fractured by either explosive charges placed in the mold pack or by high energy pulsations directed at the mold. Once the mold is fractured and broken into various pieces it may then be dislodged from the casting.

The present invention is directed to polyisocyanate addition compounds which i) are substantially free from isocyanate groups and are prepared from one or more a) polyisocyanate adducts containing uretdione, biuret, allophanate, carbodiimide and/or oxadiazinetrione groups and/or b) NCO prepolymers, ii) contain urethane groups, iii) contain fluorine (calculated as F, AW 19) in an amount of 0.01 to 50% by weight, and iv) contain ethylenically unsaturated groups (calculated as C═C, MW 24) in an amount of 2 to 40% by weight, wherein the preceding percentages are based on the solids content of the polyisocyanate addition compounds and wherein fluorine is incorporated by reacting an isocyanate group with a compound containing two or more carbon atoms, one or more hydroxyl groups and one or more fluorine atoms to form urethane groups and optionally allophanate groups, provided that more than 50 mole % of the groups that chemically incorporate fluorine into the polyisocyanate addition compounds are urethane groups. The present invention also relates to the use of the polyisocyanate addition compounds in coating compositions curable by free radical polymerization.

Methods for predicting the development of sepsis in a subject at risk for developing sepsis are provided. In one method, features in a biomarker profile of the subject are evaluated. The subject is likely to develop sepsis if these features satisfy a particular value set. Methods for predicting the development of a stage of sepsis in a subject at risk for developing a stage of sepsis are provided. In one method, a plurality of features in a biomarker profile of the subject is evaluated. The subject is likely to have the stage of sepsis if these feature values satisfy a particular value set. Methods of diagnosing sepsis in a subject are provided. In one such method, a plurality of features in a biomarker profile of the subject is evaluated. The subject is likely to develop sepsis when the plurality of features satisfies a particular value set.
