Patent DE-2321540-A1 (DE)
Title: Conveying mechanism in packaging machine - heat-sealed packages moved step by step
Inventor: VOEGELE GUENTHER
IPC: B65B43/48
Filed: 1973-04-27
Abstract: The packages have projecting heat-sealed joints on the top and bottom faces, lying across the direction of movement through the machine. In known methods of moving the packages, a driving force is applied to these upstanding seams. In the invention the faces of bars fixed to plates act as sprags and prevent the packages moving when the frame with guide bars moves one package width leftwards. A plate now pushes the next package forward. As the frame moves to the right the grip of the plates is sufficient to move the packages under the inclined faces of the sprag bars. By this means the force on the heat seals is decreased avoiding damage and allowing thinner material to be used.

Title: Multichannel direction finder - reception channels are designed for greatest possible dynamic range
Inventor: PFAFF KLAUS DR ING
IPC: G01S3/14
Filed: 1973-09-18
Abstract: Wide range is realised by the possible use of a nonlinear (e.g. logarithmic) output-input characteristic. In the case or signals of extremely short duration, in order to avoid any loss of time, the characteristic data for the bearing are processed with a simulated signal, so that different transmission properties of the channels used are eliminated, and data so obtained are used for reconstruction of the correct result, e.g. the d.f. ellipse in the case of a Watson-Watt direction finder. When the method is used for a Watson-Watt direction finder, signal amplitudes in the two channels, and their phase relations to a third, reference channel, are used for the ellipse description.

Title: Electric storage heater - fully automatic, without mechanical flaps, and temperature controls
Inventor: BENNER GERHARD
IPC: F24H7/04
Filed: 1974-07-31
Abstract: Heater storage core, has inverted U-shaped air guide channels, and warm air chamber below it. The air channel ends open into the chamber, and outlet slits open into the room to be heated. A blower at the side of the heater feeds drawn-in air from the room through a cold air chamber, below a warm chamber, and through pipe entries, passing through the latter, into the inlet end of the air channels. Flap-less apertures between the cold-and warm air sections feed part of the cold air into the warm air chamber. The ratio of flow profiles between cold air chamber, and guide channel ensures that the amount of cold air passing through the flap-less shunt apertures, is controlled dependent upon the static pressure near the lower end of the cold air channel, which changes dependent upon core temperature.
