Title: Matchbox handling system - transporting boxes with long sides across and including a buffer section
Inventor: ANDERSSON NILS OLOF BIRGER
IPC: B31B13/00
Filed: 1979-04-26
Abstract: In a handling system for the inner and outer boxes of matchboxes the long sides of both boxes are aligned transversely to the direction of transport. The boxes are taken along a production line which is partly designed as a buffer section. They are taken to the filling machine in one or two pairs of transport lines. The new system is labour saving and saves floor space required at the filling machine for buffering purposes. Specifically the boxes from the inner box machine and the outer box machine travel on the path sections with their long sides transversely to the direction of motion. A distribution directs the two paths into four paths for a buffer which takes the boxes in a descending zigzag path by a jet stream.

Title: Liq. cooled resistor with inner spindle - has cavity closed on one side at coolant outlet and fitted with liq. tight gas valve
Inventor: WAEDT GUENTER
IPC: H01C1/082
Filed: 1979-11-28
Abstract: The resistor consists of a hollow body (1) coated with a resistance layer (2). The body houses a spindle (3) in the form of a hollow body, whose cavity is opened downwards and closed at the top end by a gas valve (11), hermetically tight in relation to the liquid coolant. Between the hollow body and the spindle is a passage (14) for the coolant through-flow. The lower end of the passage is connected to the coolant inlet branch (4) while the upper end is connected to the coolant outlet (5). The spindle cavity (8) is completely filled with the coolant. In the case of coolant supply, the coolant in the passage is heated and the heat transmitted by the spindle body to the coolant in the cavity. Should the coolant in the passage evaporate, the vapour passes through the gas valve into the cavity and provides a pressure equalisation between the passage and the cavity. In this manner, the cooling effect is maintained for a certain period, if the coolant supply has failed.
