Abstract: A semi-trailer landing gear, in particular to support trailers, with a support element which includes an outer sleeve and an inner sleeve and which can be displaced in a telescopic manner in relation to the height. The outer sleeve includes a securing flange which can be applied to a vehicle. The aim of the invention is to develop a semi-trailer landing gear which is economical to produce and can also withstand high loads. The aim is achieved by virtue of the fact that the outer sleeve and the securing flange are made of a single piece of flat steel by edge rolling.

At least the inner sleeve has a wall plate joined to two adjacent side walls with welding seams that improve the bending stiffness of the support jack. The welding seams can be located inside or outside either of the sleeves. Such a support jack can be located on the lower side of any vehicle.

Abstract: A fluid operated linear drive in which on the outer periphery of a centering portion (24) fitting in a housing tube (4) at least one housing cover (5) has an annular groove (28) accommodating an annular seal (32). The outer flank (36), which is on the side of the housing tube (3), of the annular groove (28) is a component of cap part (42), which is coaxially mounted on the centering portion (24) and fixed on the housing cover (5). This division into two parts facilitates production of a flash-free annular groove (28) without fettling.

Abstract: A support jack for supporting semitrailers including a vertically telescopically displaceable supporting device having an outer sleeve and an inner sleeve. A spindle nut has projections and contact elements for being positively detachably connected to the sleeves. The projections interact with openings of the inner sleeve for fixing the spindle nut in the direction of the longitudinal axis of the support jack. The contact elements interact with an inner side of the outer sleeve for fixing the spindle nut in the direction of rotation about the longitudinal axis. A method of assembling a support jack is also described, in which the spindle nut is connected detachably to the inner sleeve by at least one translatory and one rotary joining movement or at least two translatory joining movements.

Abstract: A semitrailer landing gear, particularly for supporting trailers, including a supporting element, which can be telescopically displaced in the height thereof and which has an outer sleeve and an inner sleeve, the outer sleeve having a fastening flange for placing on a vehicle. The aim of the invention is to develop semitrailer landing gears with a reduced weight as well as with favorable manufacturing costs. To this end, the invention provides that at least one lateral wall of the outer sleeve and/or of the inner sleeve is provided with an angled wall section extending in an axial direction.

Abstract: An actuator or servo device comprises an actuator member adapted to move linearly in the motion space of an actuator housing, a microwave position detecting device for detecting the position of the actuator member in the motion space, the actuator member being capable of producing a pressure wave acting on the position detecting device on approaching the position detecting device and a high frequency microwave antenna arrangement for emitting and receiving microwaves, which are at least partially reflected by the actuator member. The actuator device includes dielectric guard cover means, arranged in front of the microwave antenna arrangement. For mechanically uncoupling the guard cover means from the microwave antenna arrangement between the guard cover means and the microwave antenna arrangement a clearance is maintained to allow deformation of the guard cover means thereinto owing to pressure waves.

Abstract: The invention relates to antimicrobial preparations which comprise octenidine dihydrochloride in liposomes. The invention additionally relates to a process for manufacturing the preparations and to the use of phospholipids for manufacturing antimicrobial preparations which comprise octenidine dihydrochloride. The preparations show a low cytoxicity.

Abstract: The invention describes an arrangement of lubricating grease inside the housing of a gear unit with rotatable components, particularly the gear unit of a jack. It also describes a grease pouch for receiving lubricating grease and a method for lubricating the gear unit with lubricating grease. Since the gear units are often not transported in their installed position, oil that has separated from the lubricating grease may leak from any gearbox openings. Thus, one of the objects of the invention was to provide an arrangement of lubricating grease in the housing of a gear unit, which on the one hand provides lubrication of the gear unit so that it is ready for operation in its delivery condition and on the other hand effectively prevents the oil separated from the lubricating grease from leaking prior to initial startup. This object is attained by enclosing the lubricating grease within at least one grease pouch prior to initial startup of the gear unit.

Abstract: A support jack, in particular for supporting semitrailers, includes a vertically telescopically displaceable supporting element having an outer sleeve and an inner sleeve, each sleeve having a rectangular cross-section with four sidewalls in each case. At least one sidewall at least of the inner sleeve has an additional wall plate. Another alternative proposes that at least one sidewall at least of the inner sleeve consists of a wall plate which the two adjacent sidewalls are fixed. An arrangement of such a support jack on the lower side of a vehicle is also described.

The gear shift also has a free floating gear between two shift positions and can be shifted very conveniently.

Abstract: A piston for a fluid operated power cylinder has two mutually coaxial sealing lips axially extending away from each other and being able to radially yield, for sealing engagement with the piston running face of the power cylinder and adjacent to at least one piston end side an elastic buffer body serving for shock absorbing in the end of stroke position of the piston, said body having an impact face facing away from the piston. At least at one piston end face the sealing lip itself constitutes the buffer body and has the impact face at its end, groove-like recesses being formed on the inner periphery of the sealing lip with a distribution in the peripheral direction, such recesses opening toward said impact face.
