Abstract: A guide bush for an adjustable length column for chairs, tables or the like is provided, in its inner portion, with a slide bush concentric of a central longitudinal axis for the guidance of a cylindrical housing of a gas spring. The outside wall of the slide bush is provided with spaced ribs for the reception and support, radial to the axis, in an upright tube of the column. The ribs are elastically deformable radially to the central longitudinal axis.

Abstract: The invention relates to a piston pump with a piston received axially displaceably in a pump bore. To improve the aspiration performance of the piston pump. A cuff with a U-shaped annular cross section is provided, the cuff is inserted into the pump bore surrounding the piston, an outer lip forms a diaphragm, which rests against a wall of the pump bore and is acted upon on its outside with ambient pressure through a venting bore. The cuff is part of a fluid storage element, which makes an additional fluid volume available to the piston pump. The diaphragm acted upon by ambient pressure creates a pumping effect, if a fluid pressure in the fluid storage element drops below ambient pressure in an intake stroke of the piston.

Abstract: In order to allow for a timely and reliable recognition of a rollover event of a vehicle, the angular velocities of the vehicle about the yaw axis, the roll axis, and the pitch axis are measured by way of respective rotation rate sensors. A rollover event is signaled as having been detected if an angular velocity exceeds a definable threshold.

Abstract: Granular secondary alkanesulfonate, essentially comprising finely divided, solid sec. alkanesulfonate and an additive. This granular sec. alkanesulfonate is obtained by grinding and mixing coarse sec. alkanesulfonate with an additive. The resulting alkanesulfonate can be used in solid detergent and cleaning product compositions or directly for producing extrudates, pressed articles or compacts.

Abstract: A 90.degree. elbow for pneumatic transport pipes includes a tubular asymmetric cross-sectional expansion at the entrance side, a baffle plate along the outer elbow side and a tubular asymmetric cross-sectional contraction at the exit side of the elbow. The baffle plate is arranged at an angle between about 55.degree. and 65.degree. relative to the incoming flow direction of bulk material. The inner elbow side is defined by a quadrantal pipe shell, with the remaining area being complemented by segments to provide a closed cross section.

Abstract: A plastic sheet, which initially is biaxially stretched above its glass transition temperature and heat-set, is stretched a second time monoaxially or biaxially at temperatures below its glass transition temperature, the stretching ratio in the two directions being in the range from about 0.5 to 10%. The secondary stretching is carried out at temperatures between about 30.degree. C. and 60.degree. C.This sheet which has been stretched twice is integrated into a laminated safety glass comprising a laminate, in which the plastic sheet carrying a function layer is disposed between two polyvinylbutyral sheets which, in turn, are enclosed between glass panes.

Abstract: An undercarriage with a wheel set capable of self-steering independent of the vehicle body is disclosed. The undercarriage contains, in combination with hollow profile wheels in the wheel sets and primary elastic springs in the longitudinal direction, two lever systems which are self-adjusting, independent of each other and are arranged on the longitudinal sides of an undercarriage. The lever systems forcibly couple the axle ends of the wheel sets on the same rail in the longitudinal direction of the undercarriage and are movable only in opposite directions.

Abstract: A novel melting gasifier (7) is disclosed, in which material at least largely comprising metal is melted in a fluidized bed. The latter is maintained by oxygen-containing gas laterally injected through approximately equidistant nozzles in the lower part of the melting gasifier. A carbon carrier and from above the material to be melted are also introduced into the melting gasifier. Over at least part of the fluidized bed height, the gasifier has a horizontal cross-section, which has different dimensions in two directions perpendicular to one another. The nozzles can project by different amounts into the gasifier vessel.

Abstract: A cleaning device for an electrostatic copier of the type having an endless travelling charge carrier provided with a photosensitive surface which is electrostatically chargeable to form a latent image to which toner particles are attracted for subsequent transfer to an image carrier. The cleaning arrangement removes residual toner particles from the surface prior to the next electrostatic charging thereof and is in form of a cleaning cartridge that can be inserted into and removed from the copier in toto. The cartridge has a leading open end and instrumentalities at this end which engage the photosensitive surface of the charge carrier when the cartridge is inserted into the copier. Elastically deformable sealing elements are provided on the cartridge and at least in part bound the open end thereof, yieldingly engaging the photosensitive surface in response to the insertion of the cartridge into the copier.
