摘要:
A toothbrush is provided having two housing sections (1, 2) which are pivotable relative to one another, of which a first housing section (1) serves as a handle and accommodates a drive unit (4) for driving a drive shaft (5), and of which a second housing section (2) carries a brush-head (3), which is drivable by the drive shaft, which second housing section (2) is pivotable relative to the drive shaft (5) about a pivot (6). To warn the user against an excessive brushing pressure the toothbrush has a spring device with at least one spring (14) which acts between the second housing section (2) and the drive shaft (5), the second housing section (2) being pivotable relative to the first housing section (1) about the pivot (6) against a pressure exerted by the spring (14) during use of the toothbrush, which spring snaps when a given pressure threshold is exceeded and which pivot is disposed in the second housing section and also forms at least a part of a mechanical coupling between the drive shaft and the second housing section.

An epilator having at least two interchangeable attachments each having a different skin contact surface which defines the position of the skin relative to the epilating member when the attachment is mounted onto the epilator. According to the present system, each attachment has a coupling by which the attachment can be coupled to a driver of the epilator for vibrating the attachment.

The invention relates to an epilator (8) comprising at least two interchangeable attachments (18a, 18b) each having a different skin contact surface (20) which defines the position of the skin relative to the epilating member when the attachment is mounted onto the epilator. According to the invention, each attachment has a coupling means (50) by which the attachment can be coupled to a driving means (48) of the epilator for vibrating the attachment.

This invention relates to methods for controlling a TNI-apparatus (1). One method can measure the actual gas temperature at the outlet of the humidifier (19). One method can determine a set gas temperature (34) of the gas at the outlet of a humidifier (19) of the TNI-apparatus (1) in dependence on an ambient temperature (25) of the TNI-apparatus (1), or a set gas temperature (34) of the gas at the outlet of a humidifier (19) of the TNI-apparatus (1) in dependence on a gas flow (28) in the TNI-apparatus. One method can determine a set gas temperature (34) of the gas at the outlet of a humidifier (19) of the TNI-apparatus (1) in dependence on a comfort value (30) predetermined by a user, or adjust the heating power of a heating wire (26) in a nasal cannula (27) of a TNI-apparatus (1) in such a way that a gas exiting the nasal cannula (27) has approximately the same temperature, which the gas had when it exited a humidifier (19) of the TNI-apparatus (1). In addition, the invention relates to corresponding TNI-apparatus.

In a shaving apparatus (1) comprising a housing (2) and a shaving head (10) with a shaving-head frame (12) and a foil frame (31) at least two helical pressure springs (57, 58) act between the two frames (12, 31) and are each arranged in a circumferentially closed duct (45, 46) provided in one (31) of the two frames (12, 31), which duct also accommodates a piston-like pressure member (47, 48) which projects from the relevant duct (45, 46) and bears against the other one (12) of the two frames (12,31).
摘要:
In a shaving apparatus (1) comprising a housing (2) and a shaving head (10) with a shaving-head frame (12) and a foil frame (31) which can be locked thereto the two transverse side walls (15, 16) of the shaving-head frame (12) are extended relative to the two transverse side walls (35, 36) of the foil frame (31) in a direction towards the housing (2) of the shaving apparatus (1) by a wall extension (61, 62), and on each wall extension (61, 62) a latch (65, 66), which extends substantially in the direction of the wall extension (61, 62), is supported so as to be movable transversely of the wall extension (61, 62) against spring force to provide positive locking of the foil frame (31) in the shaving-head frame (12).
摘要:
The invention relates to a nasal cannula for an anti-snoring apparatus, comprising a forked tube pneumatically connected to apertures, which are embodied and positioned in such a way that air can be administered into the nose of a user via these apertures. The nasal cannula further comprises a heating wire extending in the interior of forked tube in such a way that the heating wire can heat the air supplied through the forked tube. The invention moreover relates to a nosepiece and to a Y-shaped element for nasal cannula including internal radius steps at tube connection points. The invention further relates to a nosepiece and to a Y-shaped element having rounded off transition regions. The invention finally relates to a method for avoiding condensation in nasal cannulas. To this end, the gas is heated as it flows through the tubes of a nasal cannula.
摘要:
In a dry shaving apparatus comprising a shaving head frame (5) detachably fixed to the basic apparatus (1) by at least one resilient latch element (2, 3) and carrying an apertured shear foil (4) and a slidable shutter (6), which serves to optionally cover or expose the apertured shear foil and which, when it is displaced in the direction away from the apertured shear foil, is displaceable into a switching-on position and subsequently into a further position, in which the motor current circuit is interrupted, it is ensured that the latch element cooperating with the shaving head frame is connected to a slide (17, 18), which is displaceable parallel to the direction of displacement of the shutter and cooperates with a spring (22, 23), which attempts to pass the slide and the latch element to the latched position holding the shaving head frame and the shutter, when it is displaced from the switching-on position to the further position, can be positively coupled after the interruption of the motor current circuit with the slide and the slide can be taken along by the shutter, the latch element being moved out of the latched position holding the shaving head frame and the shaving head frame being disengaged.
摘要:
A device for transferring sample vessels carried by a microtiter member to collecting vessels which are carried in cassettes and are dimensioned to accommodate the sample vessels. The device is composed of a table provided with a distributor plate for receiving and supporting the microtiter member and which is provided with openings corresponding in number to the number of sample vessels, each opening being located to lie below a respective one of the sample vessels when the microtiter member is supported by the plate; an intermediate plate disposed below the distributor plate and provided with a plurality of openings equal in number to the openings in the distributor plate and each associated with a respective distributor plate opening; a distributor system extending between the distributor plate and the intermediate plate for transferring a respective sample vessel from each distributor plate opening to its associated intermediate plate opening; and a base plate disposed below the intermediate plate for the orderly accommodation of the cassettes in a manner such that each collecting vessel is located below a respective intermediate plate opening.
