An arrangement for determining the axial play between the stator and the rotor of an electric motor, especially of a small-size electric motor, includes resilient elements which mount the respective electric motor on a stationary support for oscillatory movement relative thereto, an electromagnet which causes the electric motor to oscillate in a predetermined path at such a frequency and amplitude that, so long as there is an axial play between the rotor and axial bearings thereof, the rotor will conduct movement not only with, but also relative to, the stator, which results in axial impacts between the rotor and the axial bearing and in a complex motion of the stator which has the effect of the impacts superimposed on the basic motion. The arrangement further includes a sensor which detects the complex motion and generates an electric signal representative thereof. The electric signal may then be compared with a reference signal and, in the event of discrepancy, which is attributable solely to the effects of the axial play and the resulting impacts, a command signal may be issued which controls the operation of an automatic device adjusting the position of one of the bearings toward reduction or elimination of the axial play.

A gas generator has a housing extending along an axis and having a front end and a rear end, a propellant charge in the front end of the housing, and an electrically firable igniter in the housing adjacent the charge. An end fitting fitted to the rear end of the housing is formed as a plug. Electrical contacts exposed at the end fitting and extending therethrough are connected to the igniter.

The invention relates to an implant, a therapeutic agent, the use of micelles, which are formed from both surfactants as well as active substance molecules, and to a micelle. In order to achieve a defined delivery behavior through pores of a diffusion element, the active substance molecules are covered with surfactants.

The invention relates to a depilation apparatus, in which a driving roller (3) and a drive roller (4) are provided with tooth means (5, 6) and form a roller pair, the rollers performing a rotary movement which is directed into the interior of the apparatus at the location where they interengage circumferentially. The driven roller (4) of each roller pair has teeth (5) along its entire circumference but the driving roller (3) has teeth only along part of its circumference, so that the rollers intermesh only during part of a revolution of the driving roller.

A dry shaver comprises a basic unit housing together with a shaver head having a longitudinally extending upper blade and a reciprocatorily drivable longitudinally extending lower blade acting in conjunction therewith. A swinging bridge is secured in the basic unit housing and has a reciprocatory output part for driving the lower blade and a stationary base part provided with an aperture. An electric motor having an essentially-cylindrical housing has one end of the motor housing connected to the stationary base part of the swinging bridge, the drive shaft of the motor extending through the aperture in the base part into the output part of the swinging bridge. An eccentric on the drive shaft drives the output part. A frame-like motor support has a transverse U-shape, one end of such support being connected to the stationary base part of the swinging bridge. The support has two longitudinal sections parallel to the motor drive shaft and partially enclosing the motor housing to form motor bearing surfaces, and a transverse section at its other end to support the other end of the motor housing. Two spring-action tongues are connected to the stationary base part of the swinging bridge respectively adjacent the opposite ends of the shaver head. Two catches are respectively provided at the free ends of the tongues for securing the shaver head. Two shaver-head bearing surfaces are provided on the stationary base part of the swinging bridge respectively adjacent the tongues, the catches pressing the shaver head against such latter bearing surfaces. The swinging bridge, the motor support, the tongues, and the shaver-head bearing surfaces are formed from a plastic as a single-piece component.
摘要:
A cooling arrangement for liquid-cooled internal combustion engines, with the cooling arrangement including a heat exchanger constructed as a radiator for effecting cooling between air and a coolant liquid. The cooling arrangement includes a housing accommodating a thermostat with a mixing chamber, defined in the housing, being connected with a return flow coolant tank. The thermostat is adapted to provide for temperature dependent regulated portions of cooled and uncooled liquid coolant flowing into the mixing chamber. The housing of the thermostat, a bypass connection piece, and an outlet connection of the housing are molded, in one piece to the return flow coolant tank of the heat exchanger. A lid or cover provided with recesses as well as window-like openings formed in a portion of the housing form an inside connection between the return flow coolant tank and the mixing chamber with the connection being controlled by a radiator valve disk of a thermostat insert of the thermostat.
