Abstract: An actuating mechanism for a vacuum-type interrupter with a contact spring. The actuating mechanism of a vacuum-type interrupter has a pivotally positioned two-armed lever and a spring which holds the contact force ready and which engages with the lever. The two-armed lever is guided with limited displacement in a bearing in a direction which runs approximately parallel to the actuation direction of the interrupter. While enabling, the two-armed lever pivots about a bearing bolt around the end of the bolt guiding until the contact elements engage each other. The further pivoting of the lever takes place around a linkage assembly between the two-armed lever and the actuating impact rod. The two-armed lever can be formed from two parallel split levers with a clearance such that the spring can engage between the split levers. The actuating mechanism is suitable for one or multiple vacuum circuit breakers, e.g., for use in gas insulated switchgear.

Abstract: Four shafts fitted with eccentric weights are arranged as four parallel lines with one pair placed immediately above the other pair and the ends of each are fitted with a notched driving roller. A double-notched belt driven by a motor passes alternatively under and above the rollers for the first pair of shafts, around a return, and above and under the rollers for the second pair of shafts. Idler rollers are associated with each shaft to ensure that the belt moves properly. By means of a slide, the motor and the return can be moved laterally in relation to the shaft lines, thereby permitting the continuous adjustment of the relative position of the eccentric weights for each pair of shafts. Therefore, the level of the resulting force of vibration is adjustable to between a maximum value and a zero value.

Abstract: In the case of a drive for a male-die-side ejector slidably disposed in a slide of a mechanical metal-forming press having an angle lever which is pivotably disposed at the slide, one leg of the lever acting upon the end of the ejector facing way from the male die and the other leg thereof being acted upon by a control cam which is driven in a timed manner and being held in contact with this control cam, a free adjustability of the moving characteristics of the ejector is achieved in that the control cam is provided at a control carriage which is slidable in a guide fixed at the frame in parallel to the moving direction of the slide, and at which a control connecting rod is applied in a bearing, this control connecting rod, at one end, being disposed eccentrically on a shaft serving also as the drive of the slide.

Abstract: An improved ball screw assembly is disclosed in which a return tube has a pair of minor legs which enter into two ends of the internal helical groove within a nut to return ball bearings between the two ends. Apertures are formed within the nut such that the return tube can be mounted as a one-piece item by moving it perpendicular to the central axis of the screw into the two apertures. The apertures are formed by removing all material which would normally be radially outward of the minor legs, and would prevent mounting of the return tube by moving it perpendicular to the axis of the screw. Due to this improved arrangement between the return tube and the nut, a one-piece return tube can be utilized which contacts the end of the helical groove at an angle parallel to the helix angle and tangent to the helical groove at the ends.

Abstract: In a screw and nut driving device with low internal friction, e.g. a ball nut mechanism, irreversibility is effected in a simple and efficient manner when the nut is rotatably driven and enclosed by an annular space in which a helical spring is arranged in such a manner that its ends are acted upon by the driving force from the external driving source, thus that the spring can rotate freely in the space. When the external driving source is disconnected and the nut, due to axial load is subjected to a torque, the ends of the spring are acted upon thus that the spring is deformed to friction locking against a non-rotating surface, whereby the nut is prevented from rotation.

Abstract: A wobble device is provided including a circular platform, a structure for pivoting the platform to achieve a wobbling movement, a shaft transverse to and positioned in a center of the platform, a moveable carriage rotatably attached through an arm to the shaft, a roller structure for moving the carriage on an upper surface of the platform, and a support frame below the platform. A forcing structure attached to a plurality of extension members downwardly directs the platform tilting an end of the platform toward the support frame. As the platform inclines towards the forcing structure, the carriage also begins to rotate. Once in motion, only a minimum amount of electrical energy is needed to maintain the wobble. As the carriage rotates, it turns a spur gear system attached to the center shaft. This rotational movement is then transferred through the gear mechanism to an armature of an electrical generator fastened to the platform upper surface.

Abstract: A gear arrangement includes a first gear wheel 10 having a section 12 with missing teeth. A second gear wheel 14 is arranged to mesh with the first gear wheel 10. The first tooth 16 on the first gear wheel 10 to engage with the second gear wheel 14 (following the missing teeth section 12) is resiliently movable inwardly within a radial slot 18 to withdraw when engaging an opposing tooth 22. A spring 20 urges the tooth 16 outwardly to one side of the opposing tooth 22 and into a gap on that side of the opposing tooth 22, so as to align the first and second gear wheels. Such a gear arrangement has particular use in a geared value setting mechanism provided on a print drum shaft of a postage meter.

Abstract: A pretensioned cable transmits power along a first support member (link) from a rotary actuator to a rotating output joint, typically an output pulley fixed to a second link arm but rotatable in a coupling between the first and second links. A reducer, typically two sets of coupled idler pulleys of different diameter, is mounted at a point removed from the actuator, and preferably as close as possible to the output joint. An axially split spool mounted on the actuator output wraps the outgoing and returning cable sections on different halves of the spool in opposite directions to provide pretensioning of the cable in the entire cable circuit at one point. The links and pulleys of the transmission are long and narrow. This high aspect ratio provides a compact configuration that is conductive to whole arm manipulations where any exterior surface of the links can engage an object.
