Title: Diffusion burner, esp. for tunnel kilns in ceramics industry - uses air of combustion at low pressure, reducing size and cost of air compressors
IPC: F23D14/24
Filed: 1980-06-11
Abstract: Air of combustion is fed through a side inlet into an outer burner tube(I). Inside tube (I) is a coaxial tube (II) through which fuel gas flows into tube (I); and on the outside of tube (II) are helical blades imparting a swirling motion to the air flowing along tube(I). The outlet end of tube (II) is closed, but near the outlet end are numerous radial outlet holes downstream of the blades. The gas outlet holes in tube (II) are pref. aligned in helical rows, where the helices run in the opposite direction to that of the helical blades. The outer edges of the blades are pref. not in contact with the bore of tube (I). The burner can be operated at higher gas pressures but lower air pressures than conventional burners, so smaller air compressors using less energy can be used to reduce costs. For example, this burner can be operated using a gas pressure of 150-200 mbar with an air pressure of only 26 mbar.

Title: Continuous wave radio transmission with automatic balancing - emits measuring signals from centre at critical frequency to establish transit time differences
Inventor: BERGER KURT DIPL ING
IPC: H04H20/67
Filed: 1980-09-22
Abstract: The continuous wave radio transmission system has a number of transmitters and a configuration which balances the differences in transmit time. Transmission is via cable and at different frequencies. They are linked to a transmission centre. The balance occurs automatically. The transmission centre (CC) emits predetermined measuring signals sequentially to the individual continuous wave radio transmitters (TRM1-n). The measuring signals are at a critical frequency as regards the transmit time differences. The time differences established for all the transmission times are used to set the transit times for the individual radio transmitters. This is achieved by inserting all pass filters.

Patent DE-3101978-A1 (DE)
Title: Camping caravan
Inventor: BUSCH FRITZ B
IPC: B60P3/34
Filed: 1981-01-22
Abstract: The invention relates to a camping caravan having curved upper and lower front-end parts which run into one another, straight side walls and a rear wall as well as at least one entry door. The invention has the object of further refining a camping caravan in such a manner that optimum utilisation of space along with the best possible running characteristics are achieved. The solution of the object consists in that the surface of the rear wall is of straight design and in that the entry door is arranged in the rear wall. With these two features, the essential advantage is achieved that an exceptionally favourable flow behaviour during driving is achieved by a rear-wall surface of straight design because the rear wall is used as a breakaway edge for relative winds impinging on the front-end parts and, as a result, a particularly aerodynamic shape is achieved.
