Abstract: A calender roll wherein a stationary shaft is spacedly surrounded by a cylindrical shell and carries a row of bearing elements which are movable by pairs of cylinder and piston units and have convex surfaces formed with pairs of fluid-filled pockets adjacent to the internal surface of the shell. Each pocket receives pressurized hydraulic fluid from the cylinder chamber of a different unit, and the cylinder and piston units for each bearing element are adjacent to each other, as considered in the circumferential direction of the shell. Those portions of the pockets which are remotest from a symmetry plane including the axis of the shell and extending between the pockets of each pair are bounded by arcuate lands. The lands which extend circumferentially of the shell are parallel to each other, and the pockets of each pair are separated from each other by a land which is halved by the symmetry plane. The bearing elements are separated from each other by narrow gaps extending circumferentially of the shell and bounded by parallel side faces of the respective bearing elements. The magnitude of forces acting upon the internal surface of the shell is substantial in the regions of the gaps and increases gradually toward the central portions of the bearing elements, as considered in the axial direction of the shell.

Abstract: Each tamping unit of the tamping machine has a gantry (6) which is inclinable transversely to the track and in which the tool holder (3) is mounted for vertical movement. The amplitude of the downward movement of the tool holder (3) is regulated by a device (16 to 21) controlled by a command level corresponding to the depth of tamping desired. In order to correct the differences (E) between the depth of tamping reached and that desired which are caused by the inlination of the gantry (6), the command level is lowered by a distance substantially equal to the differences by a correction device comprising a mechanical feeler (25) for detecting the inclination of the gantry (6) and a mechanical connection (26, 34) connecting the said feeler to the sensitive member (16) of the regulating device in order to vary the zero thereof. In a variant, this correction device is formed of an electronic circuit which permits the cancelling of the differences (E).

Abstract: A tool for stripping surface layers from elongate objects includes an elongate frame, a jaw means which extends along the frame and which is pivotally mounted in the frame and a leg which also extends along the frame and which is pivotally mounted in the frame. When the leg is pivoted towards the frame, the leg is arranged to swing the jaw means towards the frame, via a camming arrangement, against the action of a restoring means. At one end of the tool, the frame and the jaw means have mutually facing clamping surfaces, and a stripping knife means which is arranged between the frame and the jaw means for movement therealong from a starting position adjacent the clamping surfaces. The stripping knife means includes two carriers for a respective one of two stripping knives which are arranged to be brought together by means of the jaw means and which extend transversely relative to the frame. The leg extends from the location at which it is connected to the frame for pivotal movement of the leg, substantially to the region of the part of the jaw means provided with clamping surface adjacent the aforementioned one end of the tool, thereby to cover at least the upper side of the jaw means remote from the frame.

Abstract: In a vehicle seat for at least two people consisting of an understructure with supports and bars connecting the latter on which at least two seat surface parts are arranged with backrest parts hinged thereto, at least one seat surface part being mounted on the bars so as to be transversely displaceable and fixable, in particular for omnibuses, a technical problem consists in the requirement to design such seats for installation in the vehicle both on the right hand side and on the left hand side since the seat surface part which is on the window side in each case does not need to be displaced transversely. Due to the measure that the bars (19) are of straight-line construction with regard to their height above the upright surface (10) of the seat (14) and both seat surface parts (15, 16) are mounted via the bars so as to be displaceable thereon in principally the same manner, the advantage is achieved that essentially symmetrical vehicle seats are produced which can be installed both on the right hand side and on the left hand side and only the production of a single understructure is required. In this case, the bars (19) can be constructed, in particular, as rails and the seat surface parts (15, 16) can be installed so as to be displaceable thereon by means of sliding elements (30a) gripping around the rails, the sliding elements of one seat surface part being arranged, joined together in the manner of a frame, preferably in an integral frame unit (26, 27). <IMAGE>

One end of the motion generator unit (8, 8A, 8B) is fixed to a supporting structure (9) and the opposite end thereof is fixed to said striking member (6). The motion generator unit (8, 8A, 8B) is surrounded by a magnetic coil (10, 10A, 10B) for applying a variable magnetic field to the motion generator unit, said magnetic field being variable in dependence of current supply to the coil. The current supply is controlled by using control means for controlling the supply of current to the coil in accordance with a predetermined programme in order to achieve a desired striking movement.

Abstract: A cartridge (36) contains a filtration and additive medium body incorporated in a circulation conduit (37) to pick up particles of diret, hair, etc., and to emit a soluble disinfectant or similar. The cartridge can be encased, at least partly, by a rough filter grid (38), and can also add a softener and/or a perfume to the bath water. The cartridge is used to close a pair of contact spring (39) which serves to maintain closed a power circuit to a magnet valve, so that the valve is held open, allowing throughflow of bath water. It is partially soluble in water, and having dissolved to a predetermined extent it is moved by a spring, causing the contact springs to open, breaking the power circuit, and stopping bath water flow. A storage box placed on the bottom of the bath contains a motor driven water pump and air fan, and a suction device for starting the pump if the latter is not self-aspirating. A bottom part, mattress-like in formation, is thin, flat and flexible, and contains individual air and water hoses for distribution to the bath water.
