摘要： A flow controlling system having a viscosity sensitive means for producing a simulated fluid pressure which varies in correspondence with a fluid pressure at a predetermined portion of a fluid flow circuit on the basis of the viscosity of the fluid flowing through the circuit, and a pressure regulating means, that is responsive to changes in the simulated pressure, for maintaining a predetermined pressure at that predetermined portion of the fluid flow circuit. In particular, in a preferred embodiment of the invention, the flow controlling system is utilized in an engine timing control tappet system of the type having at least one expansible tappet for controlling timing of a fuel injector using oil that is supplied by a pump to an engine lubrication circuit.

摘要： A viscosity sensitive, pressure divider arrangement for use as part of an engine timing control tappet system where that system includes a block oil pressure supply, hydromechanical control valve and an oil sump, the pressure divider arrangement including an inlet chamber, a divider chamber and an exit chamber. The inlet chamber is connected to the divider chamber by means of a first connecting conduit having a relatively short length. The outlet side of the divider chamber is connected with the exit chamber by means of a second connecting conduit which has a length substantially longer than the length of the first connecting conduit. Additionally, the divider chamber includes a pressure-assist outlet aperture which is in flow communication with the hydromechanical control valve. The viscosity of oil flowing into the pressure divider arrangement will be acted upon by the combination of connecting conduits wherein the first connecting conduit is less viscosity sensitive than is the second connecting conduit. Consequently, a controlling pressure will be created within the divider chamber and this controlling (assist) pressure is communicated to the hydromechanical control valve and influences the switch point of that control valve.
摘要翻译：一种粘度敏感的分压器装置，用作发动机正时控制挺杆系统的一部分，其中该系统包括块油压力供应器，液压机械控制阀和油底壳，该分压器装置包括入口室，分隔器室和出口室。入口室通过具有相对较短长度的第一连接导管连接到分隔器室。分隔室的出口侧通过第二连接管道与出口室相连，第二连接导管的长度基本上长于第一连接导管的长度。此外，分隔器室包括与液压机械控制阀流动连通的压力辅助出口孔。流入分压装置的油的粘度将通过连接导管的组合而起作用，其中第一连接导管比第二连接导管的粘度敏感性低。因此，在分隔器室内将产生控制压力，并且该控制（辅助）压力传递到液压机械控制阀并影响该控制阀的切换点。

摘要： The present disclosure provides a microelectromechanical systems (MEMS) igniter which is an ignition safety device (ISD) in a small, low-cost, low-power, and highly reliable design. The MEMS igniter provides both out-of-line safety and an ignition mechanism for a rocket motor. The igniter is initially held in a safe, out-of-line position with respect to a propellant. Upon receiving appropriate arm and fire commands and sensing the correct environment, MEMS mechanisms move an ignition component into alignment and the device can function.

摘要： A liquid separator to extract liquid, usually water, from a water-solid mixture. The liquid separator has a housing with an inlet and an outlet separated by a liquid extraction chamber. The housing sidewalls defining the extraction chamber are porous, and are preferably comprised as a plurality of spaced apart rails or slats. The spacing between the rails provides a porosity for extraction of water. The rails are movable inwardly and outwardly relative to the housing in order to vary the volume of the extraction chamber. Bias means are provided that normally bias the rails inwardly of the chamber. A water-solids mixture is pumped through the chamber and tends to expand the chamber against the force of the biasing means. The combination of effects upon the subject mixture is to cause water extraction through both the squeezing by the slats and the friction occassioned by the dewatering of the subject mixture.

摘要： A handling system to move material and particularly manure from a collection area to a holding or storage station. The manure handling system includes a manure pump assembly having a hopper mounted over a pump housing which defines a triangularly shaped pumping chamber. An outlet valve located at the end of the chamber is urged closed by a rubber spring internally connected in the chamber. A triangular ram or piston shaped to conform to the shape of the chamber reciprocates in the pumping chamber to push manure delivered from the hopper past the outlet valve to a discharge pipe leading to a holding station. Means are provided for heating the discharge pipe and the pumping chamber, thus to permit year-round and above-ground use of the system.

摘要： A reactor for hydrolytic splitting of cellulose under high pressure and heat has an inlet and outlet each with a cross-sectional area smaller than the cross-sectional area of the reactor. The pressure and heat in the reactor forms a cellulose plug within the inlet and the outlet. The inlet plug stops cellulose from escaping out the inlet. Cellulose begins to breakdown under heat, pressure, and if required an acid or a lubricant. The outlet plug slows downstream movement of cooking cellulose. Cellulose may be pre-treated by the addition of water, a weak acid, a lubricant, or a combination of the foregoing. The outer surface of the plug cooks faster than the inner core of the plug, becomes a liquefied slurry, and slides faster towards the outlet than the inner core.
