Title: Circuit arrangement for protection of the semiconductor switches while switching a mains converter bridge, which feeds energy back into an electrical mains system, in a DC intermediate-circuit converter
Inventor: FRICKE ERNST-DIETRICH DIPL ING
IPC: H02M5/27
Filed: 1993-06-29
Granted: 1994-12-22
Abstract: It is intended to specify a circuit arrangement for protection of the semiconductor switches during switching of a mains-commutated mains converter bridge (1.2) which feeds energy back into the mains (L1, L2, L3) and effectively protects the semiconductor switches both against overvoltages and against overcurrents, at a low cost and in an operationally reliable manner. The mains converter bridge (1.2) which feeds energy back into the mains is operated, without any circulating currents, with a second mains converter bridge (1.1) in a DC intermediate-circuit converter which is operated in the four-quadrant mode. The second mains converter bridge (1.1) is connected in parallel, but in the opposite polarity to said first mains converter bridge (1.2), is mains-commutated and draws energy from the mains. In the case of the DC intermediate-circuit converter, an intermediate-circuit capacitor (3), which is connected to the terminals of a self-commutated converter on the load side, is connected via at least one intermediate-circuit inductor (5.1, 5.2) to the two mains converter bridges (1.1, 1.2). According to the invention, that output of the two mains converter bridges (1.1, 1.2) which is on the intermediate circuit side is bridged (shorted) by a short-circuiting thyristor (2.1) which switches on in the event of an overvoltage and/or in the event of an overcurrent (Id) flowing via those terminals of the mains converter bridges (1.1, 1.2) which are on the intermediate circuit side. A load-relief diode (2.2), which is connected in the opposite polarity to the operating polarity of the intermediate-circuit capacitor (3), is connected in parallel with said intermediate-circuit capacitor (3). When the short-circuiting thyristor (2.1) is triggered, the [lacuna] by the intermediate-circuit capacitor (3) and the ... stores Original abstract incomplete. <IMAGE>

Abstract: Thin-walled fibre composite rods 4, 6 are interconnected coaxially by a thin-walled fibre-composite sleeve 16 adhered thereto, the sleeve having an axial slit and comprising an inner layer 20 of unidirectional fibres, a layer thereover of unidirectional fibres which extend at an angle greater than 20 DEG  to the rod axis, and an outer fibrous woven tube 18 laminated over the sleeve 16 and the adjacent regions of rods 4, 6. The rigidity of inner layer 20 substantially corresponds to that of the fibre layer of rods 4, 6. The sleeve may be produced by removing foamed core material 8 from a length of rod, cutting the axial slit, and bending the sleeve 16 open so that the inner layer 20 breaks in the region opposite the axial slit. Alternatively, the rods 4, 6 may be wound or pultruded, and the inner layer 20 may be a fibrous braided tube with the fibres at less than 15 DEG  to the rod axis. <IMAGE>

Title: System for adjusting boot lid on vehicles
Inventor: SCHMID DIETER DIPL ING
IPC: E05D7/00
Filed: 1994-12-09
Granted: 1995-11-23
Abstract: The hollow bearing pin (12) of the bearing block is formed by a straight tubular section. A pair of adjustment devices each having a swivel mounted adjustment lever (18) temporarily adjusts the position of the swivel axis (40) of the boot lid. The swivel axis of the levers runs parallel to the swivel axis (40) of the lid. It is fixed against the force of the compensating spring (7). The lever arm (46) between bearing eye (11) on the hinge side and swivel bearing (27) on lever side can be lengthened or shortened by separate movement. The adjustment devices engage partly movable and partly form-locking outside on the bearing eyes (11) of the hinge arms (4) so that swivel movement between adjustment lever (18) and hinge arm (4) and rotation about the longitudinal axis of the lever (18) are possible but relative height displacement between bearing eye and end of lever facing same is prevented.
