Abstract:
There is disclosed a sealing bush as well as a hydraulic unit fitted with said sealing bush and a check valve. The sealing bush is made of plastic and has, on an end face, a preferably conical elevation that can be brought into sealing contact with a bearing shoulder.
Abstract:
A spectrum analysis engine (SAGE) that comprises a spectrum analyzer component, a signal detector component, a universal signal synchronizer component and a snapshot buffer component. The spectrum analyzer component generates data representing a real-time spectrogram of a bandwidth of radio frequency (RF) spectrum. The signal detector detects signal pulses in the frequency band and outputs pulse event information entries output, which include the start time, duration, power, center frequency and bandwidth of each detected pulse. The signal detector also provides pulse trigger outputs which may be used to enable/disable the collection of information by the spectrum analyzer and the snapshot buffer components. An alternative pulse detection module is provided that tracks signal pulses by comparing peak data from successive FFT cycles with existing signal pulse data that is derived from comparing peak data for prior FFT cycles. Peaks for new FFT cycles are matched to data associated with signal pulses determined to be occurring over many FFT intervals.
Abstract:
A knock-down portable partition system has cover panels supported on a post and beam framework designed for quick and easy on-site manual assembly. The framework includes at least two vertical posts and at least two structural beams rigidly, yet detachably interconnecting the vertical posts. Connectors secure the beams to the posts, such that the partition system can be assembled and disassembled manually. The partition system may include utility troughs shaped to retain wires, cabling, etc. therein to provide power and/or communication to the system. The utility troughs have opposite ends shaped to be detachably mounted to the posts.

Abstract:
A folding table is provided with a foldable leg structure. The legs fold between a first working position and a second stored position. As the legs move towards the stored position, a pair of wheels associated with the legs structure are moved into operative position, enabling the table top to be rolled easily to storage.
Abstract:
Disclosed is a 2/2 directional seal valve with direct control comprising a housing and a seat piston installed, i.e., located, in leakproof and slidable manner in the housing. The piston has a conical surface which acts together with a seating surface located in the housing to open and close a passageway for passing pressure medium therethrough. A closing spring is also provided. One end of the closing spring bears against the housing and another end of the closing spring bears against the seat piston. In order to achieve a valve of this type which, while functioning in a leakage-free manner, has a low weight and is especially suitable for use in aircraft hydraulics. The seat piston comprises a high-strength carbon-fiber-reinforced plastic and the housing comprises light metal or a light metal alloy.
Abstract:
A flow limiting throttle element for restricting the flow of a fluid guided in a delivery line, including a pressure-tight housing having a first bore hole portion, a second bore hole portion adjoining the first bore hole portion and two coaxially arranged working connections. A substantially cylindrical piston is arranged in the first bore hole portion of the housing so as to be freely axially displaceable therein, the first bore hole portion having a length that is at least 50% of the piston length. Overflow ducts are arranged in an outer surface area of the piston and the second bore hole portion of the housing has a cylindrical recess which communicates with the overflow ducts and transits into a first one of the working connections. The first working connection having an inner diameter smaller than that of the second bore hole portion. Additionally, a connection nipple is sealingly arranged in the first working connection, and has an annular end face which is situated in the housing so as to project into a region of the cylindrical recess and form a sealing fit with a first end face of the piston which faces the nipple end face. A first continuous slot is arranged on the first end face of the piston so as to continuously communicate with the cylindrical recess of the second bore hole portion without regard to the axial position of the piston.
