Abstract: In order to avoid the specific disadvantages of screwed and welded connections of pipe ends, a plug connection is proposed in which both pipe ends (1, 2) have a collar-like expansion, provided with a bulged section (4), the sections (4) being surrounded externally by a clamping body (14) whose design is matched to these sections with a view to producing a positive closure. Inside the collar-like expansion there is a metallic core pipe (6) which externally - overlapping its end face ends - carries annular sealing elements (7) which are provided in the region of their end face ends which rest on one another with retaining pockets for a curable plastic which is partially forced out of these pockets when external pressure is exerted by means of the clamping body (14) and at the same time fills the central annular space (15) between the bulged sections (4) on the one hand and the clamping body (14) on the other hand. This results in a plug connection which has smooth walls on the inner side, can easily be assembled and is protected against axial thrust in a reliable manner. <IMAGE>

Abstract: A hydraulic drive is shown, with which an electrical power circuit breaker can be operated. A differential piston (2) slides in a drive cylinder (3). One side of the cylinder is subjected to, or relieved from, the pressure fluid for switching on or off via a changeover valve (11). This changeover valve is excited to changeover by a hydraulic control loop. There is at least one switch-off trip device (16, 17) in this control loop. In order to improve the switching-off tripping, particularly in the event of failure or a reduction in the control voltage, an undervoltage trip device (18) with a minimum voltage trip coil (20) is connected in parallel with the existing trip devices. This coil (20) responds in the case of a specific value of the falling control voltage and causes hydraulic switching through of the undervoltage trip device (18). If this directional seat valve does not open completely, there is a hydraulic amplifier stage (21) in the control loop, which quickly opens a hydraulic bypass to the undervoltage trip device (18). <IMAGE>

Abstract: An emergency locking retractor for an automotive seat belt arrangement includes a pivotable plate (48) housed within a retractor housing (10) and pivotably supported thereon, and a pivotable tooth member (46) pivotably supported on the retractor housing. The pivotable plate is biased by means of a coil spring (54) so that the free end thereof comes into contact with a webbing (14) wound onto a belt spool (12). The pivotal tooth member is connected to the pivotable plate by means of a coil spring (56) so that the pivotable tooth member pivots depending upon pivotal movement of the pivotable plate. If essentially the full length of the webbing is drawn out of the retractor housing when the seat belt arrangement is used for fixing a child seat to a vehicular seat, the free end of the pivotable tooth member engages one of teeth (30c) formed on the circumferential wall of a cam wheel (30) which normally rotates with the belt spool in a drawn direction in which the webbing is drawn out of the retractor housing. While the child seat is fixed to the vehicular seat by means of the seat belt arrangement, the free end of the pivotable tooth member remains engaging the one of the teeth independently of operations of a webbing sensor and a vehicular sensor (35), so as to prevent the webbing from being drawn out of the retractor housing.
