A crimping tool with a housing, a motor, a switch connected to the motor for activating the motor, a pump driven by the motor, a piston driven by the pump, an indenter operably connected to the piston, and a tool head connected to the housing, wherein a workpiece can be disposed between the tool head and the indenter. A current sensor is connected to the motor for sensing current flowing through the motor. A processor receives current data from the current sensor, the processor analyzing the current data to determine completion of a crimping operation and/or an error condition. A display connected to the processor can indicate completion of a crimping operation and/or an error condition.

A pipe component with an outer pipe element and at least one inner pipe element arranged inside the outer pipe element is provided. The outer pipe element is formed as a flexible pipe element with a plurality of projections, in particular corrugations, and/or at least one corrugated portion. On at least one point the outer pipe element and the at least one inner pipe element each have a projection pointing to the outside in a radial direction, wherein the outside of the projection of the at least one inner pipe element at least partly flatly rests against the inside of the projection of the outer pipe element or of another inner pipe element, so that by means of the projections a connection exists between the at least one inner pipe element and the outer pipe element. The invention furthermore relates to a method for manufacturing a pipe component.

A method for crimping a stent with a polymer coating in a humid environment is disclosed.

A working head for a hydraulic power tool. The working head includes a head frame and a first moveable die head configured to move along the working head frame. The first moveable die head is configured to receive a first moveable die comprising a first body length and a second die head is adapted to receive a second die comprising a second body length. At least one of the moveable die or the stationary die comprises an elongated die.

A device head of a hydraulically actuatable tool includes an opposing holder which is integrally formed on the device head and which receives a first tool, and including a second tool that can be moved towards the opposing holder by a hydraulic piston. A cylindrical formation formed integrally with the device head and is provided relative to the hydraulic piston. The device head has an integrally formed toothing recess for the angular fixed, but also changeable, arrangement of a retaining rod.

An in-line portable, handheld hydraulic scissor-type action crimping tool having a handle assembly and a working head assembly is provided. The handle assembly has a tool frame portion and a neck portion. The working head assembly has a pair of jaw members joined so that they are movable relative to each other and held in place by a locking pin. One jaw member has a nest secured to or directly formed into the jaw member. The other jaw member has an indentor secured to or directly formed into the jaw member.

A work head for or of a compression tool includes a compression jaw and an abutment jaw forming an arched abutment surface having a longitudinal extension arched in a hypothetical arc plane orthogonal to an insertion direction of the object into the abutment seat. The longitudinal extension has a first side segment, a second side segment opposite to the first side segment, and an apex segment in the shape of a neck extending between the first side segment and the second side segment, and an abutment width measurable in the insertion direction and orthogonal to the arc plane. The abutment width decreases from a first base width of the first side segment to an apex width of the apex segment. The abutment width decreases from a second base width of the second side segment to the apex width of the apex segment.

A rotary shear valve includes a valve body, a first pair of teeth extending radially from the valve body in a first angular direction, a second pair of teeth extending radially from the valve body in a second angular direction, and a shear seal disc.

A method for producing a multi-layer sliding bearing includes: providing a carrier body with a carrier body connecting surface, a surface structure being formed on the carrier body connecting surface, and the carrier body on the carrier body connecting surface having a carrier body material with a carrier body strength; providing a bearing body with a bearing body connecting surface, the bearing body on the bearing body connecting surface having a bearing body material with a bearing body strength; applying the bearing body to the carrier body, a carrier body connecting surface being turned towards a bearing body connecting surface; pressing the bearing and carrier bodies together, wherein the bearing body, on the bearing body connecting surface, is plastically deformed and forms a positive locking connection with the carrier body connecting surface from the effect of the surface structure of the carrier body connecting surface.
