Abstract: Zinc and lead are separated together out of dust derived from a gas-cleaning installation in iron or steel making by a flotation-separation treatment. In order economically to provide a good separation of these metals and to leave a residue which is re-usable in an ore-preparation process in the iron and steel industry, the flotation-separation treatment is at a pH of 7 to 9 and is effective to achieve a separation, according to size of the dust particles, of a floated component in which the zinc and lead are concentrated and a non-floated component which is suitable for re-use.

Abstract: A tooth cleaning device for optimal tooth cleaning comprises, on a U-shaped carrier (109), tufts of bristles (180), which are placed against the tooth using pressure bubbles (149) under equal cleaning pressure on both sides. With this arrangement the tufts of bristles (180) are fitted to individually self-positioning rocker arms (174, 178'), in order to also engage in the spaces between the teeth, which are difficult to access. With the aid of a further pressure bubble arrangement (147) using phase-shifted pulsating pressurization, with reference to the pressure-generating bubbles (149), a wiping movement of the tufts of bristles (180) with cleaning pressure is generated in the direction from the gum towards the crown of the tooth, in counter-direction without bearing pressure on the tooth.

Abstract: The deflection of a light beam in two mutually perpendicular directions ensues by rotating two spindles which are hinged to a single deflection mirror and whose axes reside perpendicular to one another. The first spindle is hinged to the deflection mirror via a fork joint such that the trunnion axis of said fork joint and the axis of the first spindle are perpendicular to one another. The second spindle is hinged to the deflection mirror via a turning arm and a dog secured to the backside of the deflection mirror. So that the two spindles can be turned independently of one another, the dog is guided in the turning arm so as to be freely pivotable around the axis of the first spindle. The dog is preferably guided in a slot of the turning arm. Apparatus equipped with only a single deflection mirror for the deflection of a light beam in two mutually perpendicular directions are usefully employed in laser labeling.

Abstract: Seizable connection-associated switching devices emit processing requests for incoming information to a central sequential logic system. Processing requests differ on the basis of different urgency degrees which are defined by type of appertaining, connection-associated switching devices. A limit value is set in an occupation non-acceptance device based on the measure of the momentary sequential logic system load. The processing request are rejected (or accepted) by way of a comparison of the respective urgency value to the limit value which is carried out by way of the occupation non-acceptance device, being rejected (or accepted) when the urgency value is lower (or greater) than the limited value. Connection-associated switching devices having the same urgency degree are combined in different urgency groups having different urgency subvalues on the basis of their addresses. Acceptance, as well as rejection, of seizures by the occupation non-acceptance device is also carried out according to these urgency subvalues whose mutual prioritization is cyclically interchanged in uniform time intervals.
