Abstract: A method of permanently mounting bristles on a handle to form a brush, and a brush having bristles which extend preselected, irregular distances from the brush handle. First ends of bristles of substantially equal length are contacted against an insert element or a receiving body having a contour corresponding with the preselected, irregular distances. The insert element is heated to soften the bristle first ends or the receiving body, and then the insert element is cooled to harden the softened one of the bristle first ends and the receiving body, fastening the bristle first ends to the insert element. The insert element is fastened in a receptacle in the brush handle. As a result, the bristles extend from the brush handle with the corresponding contour. The several steps may be performed in various sequences.

Abstract: A method and device for enabling oscillating drive of at least one tooth cleaning element in a tooth cleaning device which includes a drive unit and motion transmitters acting between the drive unit and the at least one tooth cleaning element. A rotary motion, derived from the rotary motion of the drive unit, is converted and one of the motion transmitters in a vicinity of at least one tooth cleaning element into a cyclic linear motion directed at an angle to an axis of the rotary motion of the drive unit and transmitted to the cleaning element.

Abstract: Watertight transducer for measuring the contraction of the uterus with a transducer casing, wich has on its underside a diaphragm made from a soft material, such as e.g. elastomeric plastic. The transfer of the uterine contractions takes place from the diaphragm for a ram to a dynamometer. The interior of the transducer is vented by means of a ventilating hose, whose opening to the external air is remote from the transducer, in order to avoid measuring errors as a result of temperature fluctuations.

Abstract: A clamping contact connection is provided for contacting a fetal scalp electrode, which is fixable to the head of the fetus by means of a tubular insertion, aid with a leg plate fittable to the expectant mother. The clamping contact connection comprises a first contact element, which is at least partly wedge-shaped or tapers and has at least two outer contact faces, and a second contact element openable on its front end and which has at least two openable jaws with inner contact faces. During contacting, the jaws of the second contact element engage round at least the wedge-shaped or tapering area of the first contact element. Additional holding elements prevent the unintentional separation of the clamping contact connection. The connection permits an easy manufacture of the individual elements, good cleaning, safe and rapid connection and also separation of the contact elements, as well as adequate protection against accidental, incorrect mains connection.

Abstract: An automatic toothbrush to optimally clean at least two sides of a tooth or a row of teeth comprising a cleaning head with a substantially U-shaped support to which are mounted clusters of bristles. The clusters of bristles are mounted on self-positioning pivoting levers of the U-shaped support in order to clean even little accessible tooth locations. Using at least one mechanical and/or electromagnetic drive means, control is made possible of a phase-shifted, impulsive motion of the support relative to the automatic toothbrush and of the pivoting levers with the cleaning bristles relative to the support to implement a cleaning or wiping action by the clusters of bristles from the gum to the tooth crown while, in the opposite direction, the motion takes place with at least reduced pressure applied to the teeth.

Abstract: In a can changer device, empty cans are fed to a reserve position A and full cans are transported from a collection position C into a delivery position G by means of an apparatus for moving spinning cans. The can moving apparatus comprises drive means containing rails and a carriage movable thereon and having pivotably mounted arms. The arms are pivotable from a substantially vertical position, and specifically, to one side into a substantially horizontal position for entraining and moving the empty cans and, as to one arm of such arms, into the opposite substantially horizontal position for entraining and moving the full can. The carriage is movable to-and-fro by means of a toothed belt between a deflection or reversing head and a drive head, respectively between the locations or positions H and L. During operation, the can changer device itself moves the filled can from the position B towards the position C and the empty can from the position A into the position B.

Abstract: A pulse generator is used to emit a pulse train of specific frequency while two pick-ups--one adjacent a circumferential array of control lugs on the rotor and the other adjacent the blades--emit start counting and stop counting pulses. The number of pulses generated by an external pulse generator are counted during the time interval for the passage of two lugs past a pick-up and the time interval for the passage of two adjacent blades past a pick-up for each revolution of the rotor. A quotient is then obtained from the two pulse numbers for each revolution and the difference between the maximum and minimum values of the quotients obtained during continued rotation is determined. If the difference exceeds a preset critical value, an activity signal is generated, for example to set off an alarm.
