Abstract: A unit for processing microbiological samples has a conveyor for transporting samples, for example in microtitre plates. At a processing station, samples for processing are transferred in their sample containers from the transport device to a processing device, which can have several processing areas, of which only one is ever in a processing position. A manipulating device is associated with the processing position. A magazine dispenses sample containers for processing. An incubator accumulates and discharges sample containers using transport and storage arrangements with coupleable conveyors on multiple levels.

Abstract: A method of applying a longitudinally extending coating of a reflecting or luminescent material in a tubular lamp by means of a nozzle which travels along the longitudinal axis of the lamp envelope. A plurality of spraying jets are so disposed that the suspension or solution, lands on a portion of the envelope immediately adjacent to the slot to be formed.

Abstract: The invention relates to a method of manufacturing a tubular lamp envelope for a fluorescent lamp in which a glass tube is softened by heating, bent around abending jig by means of bending members and then cooled until the material of the tube has solidified. During the solidification the tube assumes a horizontal position and the cooperation of the bending members with the tube is interrupted.
