Abstract: A disk brake for vehicles, especially for utility vehicles, comprising brake shoes, an application on both sides of the brake disk which applies one of the brake shoes, and a force transmitting device to transmit application force to the brake shoe on the other side of the disk brake. The force transmitting device is shaped like a fully enclosed frame, which absorbs the application forces. A modular element of the force transmitting device enables brake mechanism to be premounted and improves structural rigidity.

Abstract: A brake disk for road vehicles has a brake caliper engaging about a brake disk of a vehicle wheel to be braked. A clamping unit upon which an actuation cylinder can act is provided on one side of the brake disk and which itself acts against at least one pressure member. In order to withstand the braking forces in a manner free from sealing problems, the caliper is constructed in one part such that the clamping unit is mounted in a section of the caliper which is substantially closed on all sides. When the caliper is moved away from the brake disk, the clamping unit can be introduced, in the form of a preassembled unit into the caliper through the opening therein facing the brake disk. When the clamping unit has been introduced, the opening in the brake caliper facing the brake disk is closed by a closure plate penetrated by the pressure member of the clamping unit.

Abstract: Replace the abstract in the instant application with the following abstract: A compressor has a reciprocating piston operating in a working area to compress the working medium, a drive unit for the reciprocating movement of the piston, and an intake and discharge device for supplying and expelling the working medium. The liner, in which the piston reciprocates, is manufactured as one piece with a valve plate. Further, the slider crank mechanism used to drive the piston is provided as a drive unit. As a result, the size of the compressor can be substantially reduced, virtually vibration-free motion is achieved, and the compressor reliability is appreciably enhanced.

Abstract: A process for producing a brake disc (1) for a disc brake is disclosed; in said process two separating regions (3.sub.1, 3.sub.2) are provided in a one-piece, circular brake disc (1). Said separating regions divide the brake disc (1) into two parts (1a, 1b), whereupon a fastening device (2.sub.1, 2.sub.2), which encompasses the separating region, is designed in each separating region (3.sub.1, 3.sub.2); and finally the brake disc (1) is broken apart into two parts (1a, 1b) in the separating regions (3.sub.1, 3.sub.2). Thus, a brake disc that is easier to mount and to exchange is provided.

Abstract: The invention relates to a self-propelling branch remover with the aid of which relatively large branches on trees, but even whole trees, can be gripped and capped.For this purpose, either so-called felling saws have previously been used, which were attached to the front end of a hydraulic crane and gripped the trunk with claws and sawed it off using a pivotable capping saw. The other solution was that of a worker who was lifted in a lifting basket up to the relevant place and carried out the work there manually using a saw. In both cases, the sawn-off parts dropped down in an uncontrolled manner since even the felling saws did indeed hold the piece tight, but could not hold it in the original position since they could not be used to transmit a torque to the crane arm. The attachment was effected by means of two universal joints.In the present case, this is prevented in that a connection between the felling saw unit and the machine frame is selected, which can absorb both bending forces and torques.

Abstract: An application device for a compressed-air-operated disc brake with a turn lever, an eccentric and two parallel male-threaded adjusting spindles, each of which acts via a pressure member on a brake pad and which are coupled together rotationally fixed via a synchronising device, in which an axially movable adjusting device is arranged to be integral in rotation in at least one adjusting spindle and, at every actuation of the turn lever, exerts an adjusting torque on the appropriate adjusting spindle which the synchronising device transmits to an adjuster or an actuator in the other adjusting spindle. The synchronising device is a shaft running in the region of the axis of the eccentric having a bevel gear on each face which meshes with a corresponding bevel gear of the adjusting device or the actuator.

Abstract: A pneumatically operated disk brake having a caliper actuated by an application through a traverse member which is displaceably guided with respect to the brake disk, at least one adjusting spindle is adjustably screwed to the traverse member and an adjusting device acts upon the adjusting spindle to maintain a desired ventilating play. A device is provided which prevents any rotating of the threaded spindle up to a specified torque. For a two spindle device the synchronization device can be locked in the released condition of the brake. Another solution is to provide on each adjusting spindle its brake-disk-side end a frontal toothing which engages in a corresponding frontal countertoothing of its pressure piece.

Abstract: A pneumatically operated disk brake wherein a ball socket bearing at the connection of a lever arm to a compressed air cylinder's plunger arm of a caliper includes a slide bearing between the ball and the socket of the ball socket bearing whose sliding surface, consists of at least 70% by volume polyvinylidenefluoride, at least 10% by volume polytetrafluoro ethylene and a remainder of lead.

Abstract: A process for the manufacturing of a bearing seat for a half-shell bearing in a metal part, in which the metal part is produced by a forging or casting operation with the simultaneous construction of a half-shell-shaped recess whose diameter is slightly smaller than that of the half-shell bearing. Then the recess is machined by a non-cutting process until the diameter of the recess corresponds to that of the half-shell bearing. This process is distinguished by very low costs and can also be used in limited space conditions.

Abstract: A pneumatically operated sliding-caliper disk brake wherein the sliding-caliper is mounted to two fixed guide members by two guide bearings having elastomer bearing bushings of different length bearing surfaces for displacement in the axial direction of the brake disk. The longer elastomer bearing bushing is dimensioned such that a transition fit exists to the its guide member, while the shorter elastomer guide bushing is dimensioned to have a defined play to its guide member.

Abstract: The disk brake with a caliper (2) reaching over a brake disk (1) exhibits on one side a clamping mechanism. The clamping mechanism includes a cam lever (4), which can be rotated around an axis parallel to the plane of the brake disk and interacts preferably by way of a traverse (6) with one or two adjusting spindles (7, 8), against which a brake lining (10) is braced. The two adjusting spindles (7 and 8) are coupled by means of a toothed belt (12). Into a recess of the one adjusting spindle (7) projects a rotating drive (14), which can be driven by the cam lever (4) and during the application stroke causes the adjusting spindle (7) and thus by way of the toothed belt (12) also the adjusting spindle (8) to be screwed in the direction of approach to the brake disk (1). The rotating drive (14) includes a one-way revolving coupling and a torque limiting coupling, thus preventing a screw connection of the adjusting spindles (7 and 8) during the fixed brake stroke and the release stroke.

Abstract: Cap members are placed at the lower end of the perforated bottom spool sleeve and at the top end of the perforated top spool sleeve of a series of package-containing spools mounted at a perforated tube or sword. The cap members prevent, during treatment of the package-containing spools with a suitable treatment fluid or agent like, for example, a dyeing or bleaching fluid, the escape of such treatment fluid at each of the connecting locations between the perforated sleeve of the bottom spool and a base plate as well as between the perforated sleeve of the top spool and a chuck-type or clamping closure member. The end portions of the perforated sleeves are constructed such that no treatment fluid can escape at the connecting locations between the perforated sleeves of adjacent spools in the series of package-containing spools mounted at the associated perforated tube.
