Patent DE-4402946-A1 (DE)
Inventor: HAGEN HEINZ WIESNER
IPC: B62D55/21
Filed: 1994-02-01
Abstract: In hinge chains with rubber bearings (5), in which rubberized tubular steel bushings are used as bearings for track pins (20), the bolt ends are normally provided with threaded studs to allow the steel bushings (10) to be braced immovably by screw nuts against one another and against the track pins (20). In order to lengthen the useful life of the rubber bearing (5) and to reduce maintenance, a rubberized expanding bushing (10) with at least one dividing joint (11) is proposed instead of a tubular bushing. The internal diameter (25) of the bushing (10) which is forced in is les than the diameter (27) of the track pin (20). The inserted track pin (20) expands the bushing (10) which is forced into the chain link (1). The track pin (20) is braced inside the bushing (10) and secured along its length by friction and around its periphery by friction and/or positive engagement. No screw joints are needed for bracing the bushing (10) and use of the threaded portion of the screw joint increases the rubber bearing-surface. This improves the useful life of the rubber bearing and reduces maintenance.

Patent DE-4418279-A1 (DE)
Title: Gas and particle separator assembly forming flow zones of different direction and intensity
IPC: A47L9/16
Filed: 1994-05-26
Abstract: A virtual phase-selective valve separates liquid and solid gas-borne particles from a mass of moving air within an assembly maintained at low-pressure by a suction device. Separation occurs within the margin zones of a complex ring-shaped rotating spiral of air achieved by the synergy of shaped components in a particular sequence.  Cuff-shaped flow vanes (1; 1-1; 2-1; 3) are so arranged that the air flow is subjected to no static (3; 1-3; 2-3; 3) pressure difference (3; 4) thus eliminating mechanical oscillation and acting as a virtual valve between two different flow zones of different direction and intensity (4;4) and (5;1). Further that the upper section (4; 1-4; 2) incorporates a symmetrically-charged (2; 1a + 2; 1b) centrifuge which ejects (2; 3) gas suspensions by means of the centrifugal force in the upper mass of rotating air (2;2). The ejected particles then descend down the inner face (4; 1-4; 2-4; 3) of the conical narrowing (4; 2) cuff under the influence of gravity. The guidance baffles (4; 1-4; 2-4) are so dimensioned that the gas-borne solid and liquid constituents (2; 3) are accelerated to emerge from the cuff without their helical motion generating an imbalance on the baffles (4; 1-4; 2-4; 3). The particles therefore reach the second flow zone (5; 2) and separate.

Title: Supply apparatus
Inventor: PRILLER R
IPC: H05B41/28
Filed: 1981-04-14
Abstract: In an apparatus for the supply of a direct current charge comprising, in the circuit for charging a charge inductance (L4), a main transistor (V6) operating as a switch, a protection capacitor (C17) in parallel with the main transistor reduces the losses caused by the switching of the state passing to the locked state, the discharge of the capacitor being delayed by a protection inductance. For remagnetizing said protection inductance, a free rating diode is used of which the short but high return current increases the losses caused by the switching of the locked state to the passing state. In order to eliminate such disadvantage, the protection inductance is arranged outside the charge circuit and its energy is used for additionally charging the charge capacitors (C8, C9) of an additional rectifier (G2).
