Abstract: A hydraulic control system is provided including a fluid reservoir, a variable displacement pump having a fluid input in fluid communication with the reservoir and having a fluid output, and a fluid actuated displacement control mechanism for controlling the displacement of the pump. A control valve is placed in fluid communication with the fluid output of the variable displacement pump and with the reservoir and is adapted to control the flow of fluid to a fluid actuated device. The control valve includes means for developing a control pressure signal. A sensor valve is placed in fluid communication with the control pressure signal, the displacement control mechanism, and the reservoir for placing the control pressure signal in fluid communication with the displacement control mechanism or for placing the displacement control mechanism in fluid communication with the reservoir, in response to the magnitude of the pressure control signal, thereby controlling the displacement of the pump in response to the magnitude of the pressure control signal. The control valve includes a plurality of plungers for controlling the flow of fluid between a central passageway, a supply manifold, service ports, and an exhaust manifold. Each of the plungers includes a plurality of metering notches for providing the only continuous flow path through the central passageway between the inlet and the exhaust port when the plungers are between a neutral position and an operating position. The fluid actuated displacement control mechanism is mechanically connected to the pump for controlling its displacement. The mechanism is provided with a fluid passage for placing the mechanism in fluid communication with the pump drain. The fluid passage includes a flow restriction which varies in response to the position of the mechanism.

Abstract: A centrifuge includes a power exchange rotor of efficient design which is provided with at least one channel member for guiding the flow of material therethrough from a first end exposed to a source of the material, which is a feed source in a rotor used as a feed accelerator and is material discharging from the bowl treating zone in a rotor used in power recovery. The channel is so formed as to change the direction of flow of the material at least about 90 degrees as it flows therein to a discharge outlet at the other end and is spaced from the rotor axis less than the maximum radius of the bowl in the area of the treating zone. The rotor is mounted for rotation at a rate such that the tangential velocity of the channel ends is substantially less than that of the bowl treating zone. Combined with the rotor is a means for directing transfer of the material between one of the channel ends and the annular pool in the bowl treating zone, approximately tangentially to the surface of the annular pool, while maintaining the kinetic energy of the material substantially unchanged. The rotor used as a feed accelerator is connected to a source of power for rotating it which may include a rotor used for power recovery. The rotor used for power recovery is connected to a means for deriving power from energy imparted to the rotor by the material, which means may be the centrifuge motor shaft or the bowl or other component driven thereby or an electric generator.

Abstract: A compressed-air pile-driver, especially for axially insertable tools, including a ram arranged in a housing. The interior of the housing is divided by the ram respectively into an upper compression or expansion chamber and a lower compression or expansion chamber, which can each be alternately connected to a compressed-air source via air connection pipes and a control valve, with each having an air-outlet orifice opened alternately by the ram. In the upper expansion chamber, a pressure chamber, into which the upper air connection pipe of the upper expansion chamber opens, is divided off by an intermediate plate which is approximately parallel to the end face of the ram. Located in the intermediate plate is at least one orifice which connects the pressure chamber to the upper expansion chamber, and which is closed in a leak-proof manner by the ram in its upper dead-center position, the ram additionally being retained firmly in its upper dead-center position by a retaining device. Only when a pressure overcoming the retaining force of the retaining device is built up in the air-inlet orifice is the ram thrown explosively downwards, absorbing high energy in the course of short acceleration paths. The housing of the compressed-air pile-driver is injection-molded from plastic, preferably polycarbonate resins, in order to save weight and cost.

Abstract: At the defibring/refining of cellulose-containing material, for example in the form of chips, it was found that the design of the refiner members, between which the processing takes place, the so-called refiner disc segments (Fig. 1), is of great importance for the properties of the resulting pulp and the consumption of energy at the processing. A refiner member is a plane disc, in which grooves are provided in such a manner, that between the grooves so-called bars are formed, which conventionally are formed with plane surfaces (10). According to the invention, these bar surfaces (13) have a slightly concave design with a deflection d (Fig. 3).

Abstract: The invention concerns a noise limiter, specially designed for high gas speeds, such as, for example, the exhaust from a jet engine.Current noise limiters have limitations in their noise reduction capabilities.  Furthermore they emit contaminants with the exhaust gases and also allow large amounts of energy to go to waste.The invention solves these problems by passing the exhaust gases into an inner perforated chamber (2) where the total area of the holes is considerably larger than the inlet tube's (1) cross section, and where this chamber is surrounded by an outer chamber (3) connected to the outlet (4), and filled with pieces of heat resistant material.<IMAGE>
