摘要： An equipment stand, in particular for dental implements, which consists of a carrier possessing holders for the dental implements or instruments. A stand which extends in a vertical direction, concurrently forms the carrier possessing the implement holders, so as to thereby eliminate a separate component as a carrier in the form of a cross-bar, and consequently avoids a complex construction. Furthermore, through a superimposed arrangement of the implement holders there is afforded a good overview of the implements which are located in the holders.

摘要： A dental handpiece, encompassing a gripping sleeve and a head sleeve which is bent relative to the longitudinal axis of the gripping sleeve, as well as a drive shaft which is supported within the handpiece and which drives a treating implement arranged in a head at the free end of the head sleeve. The drive shaft is transversely divided in the region of the bending location, wherein the two drive shaft parts are in interengagement through the intermediary of a follower or engaging device, and wherein a planetary ball gear drive is interposed in the driven drive shaft part. While retaining the planetary ball gear drive which acts as safeguard against overloads, it is possible, without an exchange of the complete handpiece, to effect in a rapid and simple manner a transition to working with a certain head which is selected from a large number of heads.

摘要： A circuit arrangement for controlling the action of an adjusting device, in particular of a patient chair, which comprises, as target value indicator, a digital-analog converter (1) and, as actual value indicator controllable by the adjusting device, a potentiometer (2), which receives an equalized feed voltage which serves to operate the digital-analog converter, and which is connected via a branch (13) to a comparator unit (12), whose other input is connected to output (8) of the digital-analog converter (1), and which controls the adjusting device (31, 32, 33). According to this circuit design, the digital-analog converter (1), and the potentiometer (2), form a Wheatstone bridge of which one diagonal is supplied with a single feed voltage, while the other diagonal contains the comparator unit (12).

摘要： A dental treatment apparatus having a plurality of dental instruments which are adapted to be deposited and releasably retained in an instrument holding device. The dentist is a position to store for the individual treatment instruments operating data of his own selection which will constitute fixed values. The treatment instrument will begin with these fixed values when taken into operation. However, the dentist can deviate from the fixed values and vary the operating data. The fixed values, as well as the varied operating data can be read off by the dentist on a display arrangement. After termination of the treatment, the treating instrument upon again being placed in operation commences at the stored fixed value. A data converter provides that the operating data are indicated on the display arrangement. It is possible to call up, by means of a single selecting sequence, the sets of data informations typical for treatments by all instruments which are to be employed.

摘要： A dental handpiece having a drive arrangement which provides for different speeds to be imparted to a dental tool. The drive arrangement comprises a planetary gear arrangement and a transmission member adapted for intercoupling to provide the different speeds at an output drive shaft for the dental tool. Interengagement means comprising axial slots are provided on the planetary gear arrangement, and a counter-engagement means including balls having segments which protrude from the transmission are provided to engage the interengagement axial slots to transmit the different speeds from a drive motor to the dental tool.

摘要： A turbine insert for insertion into a head-housing of a turbine elbow for dental use includes a rotatable axle which has a plurality of turbine blades disposed thereon. One of the axle-ends is adapted to receive a dental tool and a threaded cap may be attached to the head-housing. Support means are provided for receiving the rotatable axis, and the other axle-end is rotatably supported in the threaded cap through the support means. A protective sleeve which surrounds the turbine blades is formed with an opening for the passage of compressed air for driving the turbine, and at least partially surrounds and rotatably supports the dental-tool receiving axle-end through the support means.

摘要： A dental handpiece adapted for having a tool inserted into a rotationally drivable hollow shaft mounted in the nose of a straight handpiece or a head of an angle handpiece. At the end of the hollow shaft there is a radial annular flange which covers an annular bearing gap between the housing and the shaft at the end from which the tool projects. The annular flange abuts against a sealing ring which bears against the housing, and the sealing ring is completely covered by the annular flange. Between the sealing ring and the housing there is mounted a compression spring acting in the axial direction of the shaft.
