M sets of N component carriers each are placed in and removed from a component placement region one set at a time in a placement period. An empty carrier set is placed in the region as a full carrier set is removed while each set is displaced to a different one of M component placement heads having a fixed position. Each carrier receives M components. There are N sequentially occurring cycles in a placement period. A carrier of each set simultaneously receives a component in a placement cycle from a different one of the placement heads. Each head places one component at a time in a given position on a carrier in a placement cycle, each head corresponding to a given component type. The M sets of carrier are displaced simultaneously in a given cycle in the same direction in an x,y plane to a component receiving position. A given component type has the same position in each carrier.

Method of placing components on carriers and device for carrying out the

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.

Spray-coating method of window forming in tubular lamp

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.
