Abstract: The invention relates to a medical instrument having an elongated shaft, a movable tool at a distal end of the shaft, a handle with a movable grip part at a proximal end of the shaft, and a force transmission element which can be moved in the longitudinal direction of the instrument and is operatively connected to the movable grip part and to the tool such that an actuation of the movable grip part is converted into a movement of the tool. The instrument has a spring assembly that is arranged on the handle and has at least one leg spring, which has at least one winding and two legs, and a pin, wherein the at least one winding extends about the pin. When the movable grip part is actuated, a force is applied to at least one of the legs of the leg spring, said force reducing the friction between the winding and the pin such that the leg spring can be rotated about the pin and the force transmission element and the tool can be moved.

Abstract: A vehicle includes a battery housing, a plurality of batteries, and a door step. The battery housing is disposed in a floor area of the vehicle. The batteries are within the battery housing. The door step is located proximate a side of the battery housing. The door step includes an upper running board with a stepping surface and a lower bottom part that is spaced apart from the upper running board and extends parallel to the upper running board to define at least one chamber therebetween. The lower bottom part includes a central weakened area which extends in a longitudinal direction of the vehicle and is configured to permit a center region of the door step to buckle upwards in response to a lateral force greater than a predetermined threshold amount of force.

Abstract: A pipetting head comprises a carrier, at least one attachment held on the carrier and configured to secure at least one pipette tip, and two O-rings retained on the at least one attachment and configured to contact the sealing seat of the at least one pipette tip. The inner diameter of the sealing seat of the at least one pipette tip is smaller than an outer diameter of a respective O-ring where the sealing seat contacts a respective O-ring. The respective O-ring is deformed while the pipette tip is slid onto the at least one attachment to securely clamp the at least one pipette tip. The sealing seat of the at least one pipette tip is dimensioned such that the at least one attachment exerts a force on the pipette tip to deform the at least one pipette tip when it is securely clamped on the at least one attachment.

Abstract: One aspect relates to a method of producing a sleeve for a ring electrode for electrophysiological and neuro-medical applications from a biocompatible metallic tape. Repetitive structures are punched into the tape and each includes at least one surface that is connected by at least one fin to at least one external strip. The at least one external strip connects the repetitive structures to each other on the margin. A sleeve mold is formed from a multiple of the repetitive structures through multiple reforming steps by a reforming technique. The sleeve mold is punched off the such that the sleeve is formed with a first tube-shaped region with a larger diameter and a second tube-shaped region with a smaller diameter. The first region with the larger diameter has a larger external diameter and internal diameter than the second region with the smaller diameter, and the two regions are connected.

Abstract: A system for ascertaining fresh water consumption by an, in particular, commercial dishwasher (1) or a component thereof. The system includes a container (12, 22) for temporarily storing liquids, wherein the container (12, 22) has a liquid inlet (25), which can be flow-connected to a fresh water source if required, and a liquid outlet (23), which can be flow-connected to a freshwater consuming means, in particular a freshwater consuming means of the dishwasher (1), if required. The system further includes at least one pressure sensor (B3, B4) for detecting an, in particular, hydrostatic pressure in the container (12, 22), and an evaluation device which is designed to ascertain a fresh water volume flow into the container (12, 22) depending on at least one output value of the at least one pressure sensor (B3, B4).

Abstract: The invention relates to a dishwasher (100) in the form of a programmable machine for the mechanical basic cleaning of washing stock and to a corresponding method for the cleaning of washing stock. The method according to the invention comprises a cleaning phase, in which a cleaning fluid is sprayed out of a tank (4) in to a treatment chamber (2) through a line system (10) by means of a pump (8) and can flow back from the treatment chamber (2) into the tank (4) by gravity, and a rinsing phase, in which fresh water is sprayed as rinsing fluid in to the treatment chamber (2) through a rinsing-line system (15) by means of a rinsing pump (12) and can flow from the treatment chamber (2) in to the tank (4) by gravity.

Abstract: A mechanical assembly process and device for sheet metal parts (30) are disclosed. The material of the metal sheets is displaced and upset out of a sheet metal plane by a forming energy applied by means of a tool set comprising at least one male die (6) and a female mould (4) fitted with an anvil. The forming energy is generated by impact in the form of short, successive strikes.

Abstract: The invention relates to an apparatus for mechanically joining metal sheets, which lie flat one upon the other, by metal forming, having a tool set comprising at least one punch and one die which bounds a cavity in which the joining operation takes place, it being the case that at least one of these two tool parts can be driven via a driving force, produced by fluid supply, such that the punch displaces sheet-metal material out of a sheet-metal plane, and upsets it, under the action of deformation work, and the driveable tool part has a stop which is moved along with it and limits its penetration depth.

Abstract: A hydraulic ram including a stop system which defines a piston stroke. The stop system may be adjusted and the set position of the stop member may be coarsely read from graduation of a scale member while an adjustment ring has a finely graduated scale.
