摘要： An electric fluid heating device for heating comparatively small amounts of a fluid mdium, particularly for dental purposes, is characterized in that an operable controllable semiconductor, such as a transistor, is used as the heating element. The fluid heating device includes a metallic casing provided with a fluid heating chamber having a fluid inlet and outlet. The semiconductor is seated in a recess in the casing in heat exchange relation with the chamber. A temperature responsive control circuit including a PTC resistor in heat exchange relationship with the chamber is provided for regulating the current flowing through the semiconductor and thus the heat output thereof. The casing is made in two parts to permit a damaged smiconductor to be easily removed and replaced.

摘要： A hand-held instrument is illustrated wherein a counting cycle may be initiated by pressing the active electrode against a tooth to be examined. A digital to analog converter controls a battery operated current source to supply stimulating current pulses whose intensity is linearly increased in steps at the counting rate, independently of the electrical resistance presented by the external current flow path. The counter controls an indicator which displays the successive output current values, and displays the last reading for a predetermined time interval at the end of the counting cycle.

摘要： A percussion instrument suitable for use in dental practice for determining the degree of looseness of teeth has a movably seated ram which is accelerated to a defined velocity by an electromagnetic drive means and is subsequently moved toward a test subject (such as a tooth) in free flight. The electromagnetic means also controls return of the ram to a rest position. The ram is comprised of a non-magnetic section and a section of low magnetic retentivity passing through a magnetic coil. Control electronics supplies current pulses to the coil. The velocity of the ram is detected by a measuring and evaluation unit and is maintained at a constant value after a comparison of a rated value with the actual velocity value. The current feed to the coil is discontinued when the rated velocity is reached.

摘要： The invention relates to a method for producing a piezoelectric actuator in which a metallization paste is applied to a sintered piezoelectric stack and a flexible metal electrode is arranged on top of the paste. In a subsequent baking or firing step, a base metallic coating is formed from the metallization paste, whereby the base coating is permanently connected to the piezoelectric stack and to the flexible metal electrode. Alternatively, the metallization paste can be applied to a green body which is subsequently sintered so that a first layer of a base metallic coating is formed in the sintering step. A metallization paste is applied to the first layer in a similar manner and a flexible metal electrode is arranged thereon, whereby the metal electrode becomes fixed during a second baking step.

摘要： A dental installation for at least one dental handpiece having a compressed air motor drive which is supplied from a compressed air source through a compressed air conduit, and whose rotational speed is variable by means of a control valve controlling the compressed air through the intermediary of a pneumatic installation which, preferably, is constructed in the shape of a foot or pedal switch. In an installation of the above-mentioned type, by means of which there is achievable a technical operational simplification, in addition to one or more handpieces having compressed air motor drives, there is also provided a further handpiece with an electric motor drive. In particular, it becomes feasible to effect a subsequent equipping of a purely pneumatically designed dental apparatus, which only incorporates handpieces having pneumatic drives, with a handpiece having an electric motor drive, without necessitating any significant tampering with the apparatus.

摘要： A separating device which utilizes a centrifuge which is driven by a motor for processing liquids enriched with solids by forcing the solids out of the liquid against a peripheral centrifuge wall as a consequence of centrifugal force characterized that a collecting vessel is the centrifuged container. The collecting vessel or centrifuge chamber has a plurality of axially spaced partitions with concentrically arranged openings to form axially spaced chambers which will collect the solids separated from the liquid as the liquid is discharged from the device. In one embodiment, the collecting vessel and centrifuge chamber are a single molded member. In another embodiment, there are two parts, with one being a container-like part receiving an insert having the parititons.

摘要： Long-term lubrication of highly loaded lubricating areas or surfaces, such as in very high speed medical and/or dental equipment, is obtained by applying a synthetic film, for example composed of poly(fluoroacrylic acid methyl ester) onto the sliding/moving surfaces, along with a polar oil having high lubricity. Anti-microbial agents can be added to the synthetic film. A pre-coat of molybdenum sulfide (MoS.sub.2) can be provided for the synthetic film. Stationary surface abutting the sliding/moving surfaces, such as cages for ball-bearings, preferably composed of a phenol resin, can function as a reservoir for the anti-microbial agents and the oil.
