Abstract:
A tensioning device (1) for belt or chain drives comprising a tension arm (3) which carries a tension roller (4) on one end and is mounted at a second end for rotating together with a shaft (6) in a housing (2) while being resiliently supported on the housing (2) by a torsion spring (16), the tensioning device (1) further comprising a friction disk (10) which is rigidly connected to the shaft (6) or the tension arm (3), a friction lining (15,24,27) being arranged between a friction surface (10a) of the friction disk (10) and an axial contact surface (14) of the housing (2), characterized in that the contact surface (14) comprises a means (23,25,28) which engages the friction lining (15,24,27) by positive and/or force engagement and prevents any rotation of said friction lining (15,24,27) with respect to the contact surface (14).
Abstract:
The invention relates to a device for recognizing the impact site (29, 37) of a charge carrier beam on a target. This device has two position-sensitive detectors (22, 23) above the target which have a given distance from each other and from the target and on which via imaging systems (24, 25) the impact site (29, 37) of the charge carrier beam is imaged by means of X-rays. The output signals of these detectors (22, 23) are placed on a special evaluation device which determines all three spatial coordinates of the impact site (29, 37) of the charge carrier beam.
Abstract:
A color image sensor having a plurality of sensor elements arranged in a two-dimensional array, wherein the sensor elements each include an optical filter whose transmission behavior is electrically adjustable, and wherein the color image sensor includes a control for controlling the optical filters.
Abstract:
A surgical lamp includes a lamp body having at least one light source, wherein at least one bundle of light is emitted from the lamp body, a focusing device disposed in the lamp body for focusing the at least one bundle of light, and an operating device that is directly or indirectly connected to the focusing device and is configured to be covered by a sterilizable cover, where the operating device is configured to detect a predetermined motion sequence of an operator in a contactless manner and control the focusing device as a result of the predetermined motion sequence.
Abstract:
The invention is directed to a bristle for a toothbrush, said bristle being comprised of a plastic monofilament, with the preferably cloverleaf-shaped bristle body having several longitudinal ribs arranged in star shape and projecting laterally from a core section of the bristle body. The invention is also directed to a brush head for an electric toothbrush having at least one bristle tuft with at least one such bristle as well as to an electric toothbrush having such a brush head. According to the invention, the bristle of the type initially referred to is configured to be self-fanning in such a manner that the cleaning forces acting on the bristles during normal brushing cause the bristle to split open at its free end. As a result, the need to use complex splitting methods and corresponding splitting machines in the manufacture of the toothbrush can be obviated.
Abstract:
In a method for adjusting a brake system of a vehicle, braking power is automatically built up in the event of a collision. The automatic buildup of the braking power may be terminated by a defined driver response when the actuation of a driving pedal of the vehicle at a defined intensity and for a minimum period of time is maintained by the driver.
Abstract:
The present invention relates to a method for producing a brush head for a toothbrush head in which the bristle tufts that are already fixed to a bristle support of the brush head are cut at the free ends thereof such that a desired tuft end contour is generated. According to the invention, at least one bristle tuft is bent away at least in parts and held in a bent-away position while the tuft end contour of this at least one and/or of another bristle tuft is cut.
Abstract:
A lift and pivot device for a cover of a furnace including a guide housing having a base plate, a rotatably mounted slide roller, and a vertical opening; a lift pin that can be lifted and lowered inside the vertical opening; a lift cylinder for lifting and lowering the lift pin, the lift cylinder being articulated to the lift pin at one end as well as articulated and rotatably connected to the base plate at the other end; and a guide frame for carrying the cover. The guide frame includes a support arm, wherein an upper end of the support arm is equipped for connection to the cover and includes a lift nose having a lift eye which is in engagement with an end of the lift pin facing away from the lift cylinder. The support arm at the other end thereof has a slide plate.
Abstract:
A personal hygiene device is disclosed. The device includes a toothbrush; and a display for displaying interactive representations, which are controllable from the display by means of a control device. The control device includes a game controller for controlling a video game on the display and an information controller for making information available on the display, such that a switching device operable by a switching key located on at least the toothbrush or the display is provided for switching between the game presentation generated by the game controller and the information presentation generated by the information controller.
