Abstract: The instrument (10) for handling a dental part (50), for example, a male part, extends in a longitudinal axis (11) between a handling end (10c) and a connecting end (10a) for connection to the dental part (50). The connecting end (10a) has a receiving opening for receiving the head (51) of the dental part (50), which is laterally open, so that the connecting end (10a) and the dental part (50) can be connected by displacing them relative to one another transversely to the longitudinal axis (11). The male part (50) includes a head end having at least one protrusion, (53a) with which a stop (17b) that is formed on the instrument (10) can be contacted for transferring a torque generated on the instrument.

Abstract: The female part for forming a releasable connection to a male part (50) that is configured to be fastened in a mouth includes a housing (20), which is configured to be fastened to a dental prosthesis, an insert (1), which is insertable into the housing and rotatable with respect to the housing and in which a portion (51) of the male part can be accommodated, and an adjusting mechanism that is formed in the housing and on the insert and that cause a change in the diameter of the insert when the insert is rotated with respect to the housing. At least one protrusion (5b, 5c) and at least one recess are provided to form the adjusting mechanism. The female part has a locking mechanism, which is formed on the housing and in the insert for defining discretely arranged locking positions, wherein the insert is compressed more in at least one locking position than in at least one other locking position.

Abstract: A bulb is adapted to fit over a light-emitting diode emitting a light of a first hue. The bulb is composed of a light-transmitting material and defines an inner cavity. The bulb includes a color-converting insert that is positioned in the inner cavity. The color-converting insert is also composed of a light-transmitting material and includes a light color-converting material. The light-emitting diode emits light of the first hue into the color-converting insert, which converts the light of the first hue into light of a desired hue, which is then emitted into the bulb and ultimately observed over a light-emitting surface of the bulb.

Abstract: A method for an up-down converter which is based on a buck converter during the current down-conversion phase (?2, ?3 and ?5, ?6, respectively) of the coil (L1) supplies an output (B) with a relatively high output voltage (UB), where UB>Uin. The down-conversion phase of the coil current (IL1) comprises at least two different down-conversion phases (?2, ?3 and ?5, ?6, respectively). A method for an up-down converter, which converter is based on a boost converter, supplies during the current up-conversion phase (?7, and ?10, respectively) of the coil (L2) an output (D) which has a relatively low output voltage (UD) with power, where UD>Uin. The up-conversion phase of the coil current (IL2) comprises at least two different current reduction phases (?7, ?8 and ?10, ?11, respectively).
