A hydraulic unit for slip-controlled braking systems has a plurality of receiving holes for transport devices associated with a plurality of hydraulic circuits bundled into groups, wherein the receiving holes are disposed at a distance from each in parallel with the upper side and a drive shaft having eccentrics located at the plane spacing for driving the transport devices. In order to provide a compromise optimized for manufacturing a small, convenient hydraulic unit, it is proposed that three theoretical planes (E1, E2, E3) are arranged in parallel to the upper side, each receiving two V-shaped receiving holes for transport devices disposed at an angle to each other, and that the drive shaft includes three separate eccentrics for driving the transport devices.

A card connector into and from which a memory card is detachably inserted and removed, includes contacts each adapted to contact a connection portion of the memory card, and a housing for arranging and holding the contacts and having an inserting opening for inserting the memory card. The housing includes two side walls, a rear wall, and a lower wall contiguous to these side and rear walls to form the inserting opening for the memory card by these walls. A shell is arranged on the side of the housing opposite from the lower wall, and an elastically deformable tray is arranged on the lower wall so as to be slidable with the aid of a tray restraining plate. The card connector is miniaturized and lighter, more compact and simple in construction and is easy to remove a memory card.

A height-adjustable support for semitrailers, having a stationary outer support tube, an inner support tube, which is arranged in a longitudinally displaceable manner therein, and a gearbox output shaft, on which is seated in a rotationally fixed manner a bevel wheel of relatively small diameter which belongs to a bevel wheel gear stage which drives the spindle drive for the purpose of displacing the inner support tube, the drive shaft being hollow at least in its end region opposite the drive side or having a hollow extension fitted thereon.

Known apparatuses for pumping fuel have at least two suction jet pumps, which each have one drive nozzle and one collection conduit and mixing conduit located downstream of the drive nozzle. A disadvantage is that the parallel suction jet pumps require a large amount of installation space, are embodied very massively, and therefore require a large amount of injection-molding compound for their manufacture. In the apparatus of the invention, the production costs and the required installation space for the suction jet pumps are reduced. According to the invention, the drive nozzles are surrounded by a single collection conduit, narrowing conically in the flow direction and located upstream of the mixing conduits.

A vibration reduction apparatus for use with a hammer tool having a hammer piston is disclosed. The hammer piston is caused to reciprocate in the cylinder by rotation of a gear wheel and crank drive. A cam is mounted around the gear wheel, a counterweight surrounds the piston cylinder, and a cam follower is provided on the counterweight. The cam follower on the counterweight is urged into contact with the cam by a biasing element. The external profile of the cam is such that rotation of the gear wheel causes oscillation of the counterweight in antiphase to motion of the hammer piston to counteract vibrations produced by operation of the hammer action of the tool. A mechanism is provided to deactivate the vibration reduction apparatus when the hammer action of the tool is deactivated.

The beverage frothing device comprises a first beverage passageway comprised of: a first beverage suction chamber (13) in communication with a first beverage suction duct (17) and a first steam inlet duct (21), wherein the first beverage suction duct is configured for communication with a beverage container; an air inlet port (27A); a frothing arrangement for mixing beverage delivered through the first beverage suction duct (17) with air from the air inlet port (27A) and producing frothed beverage; a first beverage dispensing spout (31), wherefrom frothed beverage is dispensed. The beverage frothing device further comprises a second beverage passageway comprised of a second beverage suction chamber (15) in communication with a second beverage suction duct (19) and a second steam inlet duct (23), wherein the second beverage suction duct is configured for communication with the beverage container. A steam feeding arrangement is further provided, which is configured for dispensing steam selectively to the first steam delivery duct (21), for producing frothed beverage, or to the second steam delivery duct (23) for producing hot, unfrothed beverage.
