Abstract: A connection arrangement for axially securing a shaft-hub connection includes a shaft, a hub, and a securing device. The hub has an inner stop surface for the shaft formed by a recess and has an outer groove for axially positioning the securing device. The securing device has an axially extending sleeve-shaped part at least partly surrounding the circumference of the hub and has a radial collar at least partly engaging behind the annular end surface of the hub. The sleeve-shaped part is surrounded by a tensioning strap. A holding socket region offset radially inwards surrounds the expanded outer groove of the hub coaxially in the assembled state and can be locked in the expanded outer groove of the hub by the tensioning strap. The radial collar of the holding socket rests against an axial securing ring of the shaft in the locked state.

Abstract: A connection arrangement for axially securing a shaft-hub connection includes a shaft and a hub with an inner stop surface for the shaft and an outer groove for axially positioning a securing device. The securing device has an axially extending sleeve-shaped part and a radial collar. The sleeve-shaped part at least partly surrounds the circumference of the hub, and the radial collar at least partly engages behind the annular end surface of the hub. The inner stop surface for the shaft in the housing is formed by a recess. The securing device includes a radially deformable holding socket, the axially extending sleeve-shaped part of which is surrounded by a tensioning strap.

Abstract: The invention relates to a device (1, 1?) for the rotationally fixed connection of a drive-effective pin (3) of a gearbox to an articulated body (2) of a drive coupling of a drive shaft. In order to allow cost-effective and compact production and in order to simplify assembly and disassembly, the invention provides for the pin (3) and the articulated body (2) of the drive coupling to have respective mutually corresponding external axial toothings (11) and internal axial toothings (8) which are able to mesh with one another, and for an axial securing of the articulated body (2) and the pin (3) to be made possible by an axially displaceable bushing (12) arranged on the pin (3), which bushing (12) can be attached to a connecting portion (4) of the articulated body (2).

Abstract: An interlocking assembly system and method including an interlocking member (100) configured for insertion into a slot (22) of a tube (20), which is in turn connectable to a bracket (10). In use, slats or other pieces may be inserted into the trailing end of the interlocking member (100) and tube (20) to provide a more stable and easier to assemble structure. Applications include fencing, privacy screens, awnings, lourvre or balustrades.

Abstract: A homokinetic displacement joint for longitudinal shafts of motor vehicles, has an outer and inner joint body having ball raceways, a cage between the joint bodies, and balls provided in the individual pairs of ball raceways. The balls are guided in the cage and the ball raceways are provided in alternating sequence, alternately rising to the right and left, to form slanted, spatially arranged ball raceways in the assembled state of the joint bodies. The individual ball raceways possess a track slant angle ? 8 and an incline angle ?? 9 that are determined, relative to one another, by the ratio ?:??=5:3.

Abstract: A longitudinal shaft for use in motor vehicles consists of a tubular part having joints on both ends, corresponding to a differential side and a transmission side. There is a differential shaft and a transmission shaft accommodated on the two ends. The two joints are disposed in accommodation regions provided on the two ends of the tubular part by way of their outer hubs in a torque-proof manner. The joints are configured as a displacement joint or as a fixed joint, which can be disposed in the tubular part of the longitudinal shaft in the combination of two displacement joints, one displacement joint and one fixed joint, or two fixed joints with displacement.

Abstract: A vibrato apparatus (10) for a stringed instrument (11), the instrument having a body (12) and a neck (13) extending from the body, the apparatus comprising, tuning elements (16) on the neck and a bridge member on the body (12) to demarcate a string plane and a vibrating portion of the strings which extend in a longitudinal direction in the string plane. The vibrato apparatus (10) is secured on and is pivotal about a pivot axis which is essentially parallel to but distanced from the string plane and transversely oriented in the longitudinal direction. A plurality of vertically pivoting rocker arms (34) each securing the body end (15) of a respective string and operably secured to a lever which is resistibly secured to a spring and to the vibrato member. A slug tuning element (36) allows for vertical adjustments of the plurality of rocker arms (34) so that by varying a lever moment of the lever the plurality of rocker arms are each selectively moved thereby altering the tuning of the strings.

Abstract: A trim tab which is attached to the transom of a boat and which has a hydraulic ram which can adjust the angle that the trim tab assumes with respect to the surface of the water. In addition, the body of the tab is hydrodynamically shaped to provide very little drag.

Abstract: An ultrasonic transducer assembly having three layers. The front and back layers are made of piezoelectric materials, and are acoustically matched by the intermediate layer. The back layer functions as an ultrasound transmitter, and the front layer functions both as a transmission matching layer and as an ultrasound receiver. During reception, by delaying the signal which is generated by the front layer so that it is in phase with a signal which appears across the back layer and then adding them together, the back layer also functions to enhance the received signal.
