The invention relates to a subassembly for a brake actuator which is provided for an electromechanically operated parking brake. The subassembly comprises a drive device and gear device for generating and transmitting a torque to a brake device and a fixing element which secures the arrangement of the gear device relative to the drive device, an internal-toothed wheel of the gear device being integrated in the fixing element.

A compact, modular dosing pump system that is capable of microdose and macrodose volume flow rates, reduces or eliminates the need for additional flow control components such as temperature and pressure sensors, and utilizes a wider operational flow range than existing systems while maintaining the level of accuracy and precision exhibited by conventional dosing pump systems is provided. The dosing pump utilizes a pump and flow circuit, and a control system may be used to deliver a range of fluid volumes. The flow circuit utilizes a networked system of fluid paths and valves to route fluid through the dosing pump system in response to a pressure differential between fluid inlet and fluid outlet ports, while the controller monitors and controls the operation of the system.

A wear part (5) for detachable mounting on a supporting part in an impact-type multi-action crusher is at least partly manufactured by hot isostatic pressing. The wear part (5) has a body (19) for mounting of the wear part (5) on the supporting part and a crushing layer (20) which is attached to the body (19) and which is adapted to be brought, during operation of the crusher, into repeated contact with a raw material that is to be crushed. The body (19) is made of a substance which is easy to machine to narrow tolerances, and the crushing layer (20) is made of a material (27, 28) of high abrasive resistance. In a method of manufacturing the above wear part (5), the following steps are carried out: introducing at least one powder material (27, 28) into a capsule, degassing and sealing the capsule, subjecting the material (27, 28) in the capsule to hot isostatic pressing to form a crushing layer (20), and then after treatment of the wear part (5).

A core material-including organic core board or inorganic sintered board 1 having a plurality of band-shaped conductor patterns 2 formed on its front and rear surfaces is sliced in a direction crossing the band-shaped conductor patterns 2. End portions of the band-shaped conductor patterns 2 exposed on each of cut surfaces of the core board 1 are connected to one another by bridging conductor patterns formed on the cut surfaces. In this manner, at least one helical coil is provided. The inner diameter of the helical coil can be kept constant while coil pitch accuracy can be kept good.

Disclosed is a process for producing a substantially shell-shaped component, from substantially carbon-fiber-reinforced synthetic material having at least one local reinforcing zone and at least one stiffening element, in particular a fuselage shell, a wing shell, a vertical stabilizer shell or horizontal stabilizer shell of an aircraft or the like. The process according to the invention comprises the following steps:

• • arranging at least one doubler which has already been cured, on an at most partially cured shell skin to form the local reinforcing zone,
  • applying at least one stiffening element which has already been cured, and
  • placing at least one at most partially cured connecting angle bracket against the at least one stiffening element at least in the region of the at least one doubler, and
  • curing the shell skin and the connecting angle bracket.

Joining apparatus for joining joining elements onto workpieces, comprising a joining element holding device, which is configured to radially hold a joining element, and comprising a loading pin arrangement, which is configured to slide a joining element axially into a holding position in the joining element holding device, and/or to axially support the joining element during a joining process, wherein the loading pin arrangement has a loading pin, which is slidable by means of a loading pin actuator arrangement in the direction of the joining element holding device. The loading pin arrangement is here designed to variably establish a loading pin stroke of the loading pin between at least two stages, so that in a first stage the loading pin is displaceable less far in the direction of the joining element holding device than in a second stage.

Method for producing a resistive heating element by coating a substrate with an electrically insulating material from the gaseous phase, depositing an electrically conducting material from the gaseous phase onto the layer of insulating material deposited onto the substrate, wherein the layer of conducting material deposited onto the layer of insulating material is subsequently partially mechanically removed thereby forming at least one conductor path. The substrate is machined before depositing the insulating material thereby forming at least one recess provided for receiving the conductor path. The layers of insulating material and conducting material are deposited onto the mechanically processed substrate. Finally, the layer of conducting material is evenly removed until at least the conducting material has been completely removed from the elevated regions of the substrate delimiting the recess of the conductor path, thereby forming the conductor path. The invention also concerns a resistive heating element produced in this fashion.

The invention relates to a wedge drive for converting a vertical pressing force, including at least one slider bed, one slider wedge, and one driver; to provide a movable coupling of the slider wedge in the slider bed, at least one bearing lug is provided; the bearing lug reaches through at least one bearing opening in a side wall of the slider bed from the outside and engages in a recess in the slider wedge; the slider wedge is supported on the bearing lug and the bearing lug is supported on a wall delimiting the bearing opening.
