Abstract: The invention relates to a light vehicle such as a golf caddie which includes a body and at least two wheels that are respectively connected to the body by first and second axles. The axles can be pivoted in a first position in which they are tilted against the body and in a second position in which they extend away from the body, where the second position is defined as the driving position of the vehicle. At least one spring acts on the body and on the axles, maintaining the driving position of the axles only by the elastic force thereof, without additional transversal supports and bracing.

Abstract: A system and method for checking electrical contact points of semiconductor devices. One embodiment includes a check system and a method in which, for the checking of electrical contact points of semiconductor devices, a system is provided by which a number of contact points are impacted with a mechanical load.

Abstract: A differential gear system employs stably-oriented orbiting gears to convey drive torque from a drive shaft differentially to a first wheel shaft and to a second wheel shaft. A portion of the drive torque is conveyed to the first wheel shaft, and the remainder of the drive torque is conveyed to the second wheel shaft. The differential gear system uses a first stably-oriented orbiting inner gear to convey torque to the first wheel shaft and a second stably-oriented orbiting inner gear to convey torque to a second wheel shaft. Dual-axis couplings allow the stably-oriented orbiting inner gears to move in a translational, orbital motion, but prevent the inner gears from rotating. Each of the stably-oriented orbiting inner gears has outer teeth, whose surfaces are substantially planar. The outer teeth of the stably-oriented orbiting inner gears mesh with flat-surfaced inner teeth of hollow gears.

Abstract: The invention relates to a mechanical superharger (1) for internal combustion engines for delivaing induction air under an increased pressure and with an increased density in a combustion chamber of the internal combustion engine. The inventive mechanical superchager is comprised of a compressor unit (3) having a compressor impeller for compressing the induction air, of a clutch (2) for connecting the engine crankshaft drive, and of a high ratio gearing (4) for transferring the rotary motion of the engine crankshaft drive to the compressor impeller, whereby the gearing is provided in the form of a circuar sliding gear drive (4).

Abstract: A shear-load chuck which is mounted between two members and has a multi-layer structure for transmitting dynamic loads. The multi-layer shear-load chuck is mounted on one surface of a junction like in the traditional bushing of a shear load chuck. A support basket is arranged correspondingly on both sides of the junction and has an end plate as well as at least one strap-like loop. The end plate forms together with the at least one strap-like loop a closed load system. The support basket is attached to the shear-load chuck on one surface of the junction, while it is attached to the bushing on the other surface of the junction. It is further possible to change the cross-sectional shape of the multi-layer shear-load chuck as well as the structural shape of the strap-like loop.

Abstract: The invention relates to a device for cutting slabs or tiles, comprising a frame which has a support surface for the slabs or tiles and a cutting mechanism which is displaceably mounted on the frame, above the support surface, in order to produce a point of break in the surface of the slab or tile. According to the invention, guiding elements are provided for guiding the cutting mechanism along a curved path while it is displaced on the frame.

Abstract: An installation for filtering drinking water out of contaminated water, which can be used in many different situations, as it consists of a hydrocyclone, a micro filter unit, a unit for reverse osmosis, a mixed bed ion exchange, a re-salting unit, a unit for ozonization, an activated carbon filter and a unit for chlorinization.
