Title: Machine for wet-treatment of slivers - enclosed between porous endless belts to prevent roller-lap formation
Inventor: LUEHRMANN THEO DIPL ING
IPC: D06B3/02
Filed: 1980-03-17
Abstract: Equipment for the wet-treatment of slivers comprises a multi-section tubular conduit containing a series of positively driven guide rollers, through which the sliver is passes against a counter-current of treatment liquor. The sliver is sandwiched between two porous, endless belts, of such a width as to surround the sliver and prevent it making direct contact with the guide rollers. From the outlet of the machine, the belts are diverted back to the inlet, via adjustable tensioning rollers. This arrangement eliminates the formation of fibrous laps around the guide rollers, which require frequent stoppages for clearing. The machine is smaller, and consumes less energy, than existing machines, and can be run almost continuously without interruption due to accumulations of loose fibre.

Patent DE-3045684-A1 (DE)
Inventor: SOMMER WALFRIED
IPC: H01Q5/40
Filed: 1980-12-04
Abstract: Directional antenna system for short and ultra short waves of which the elements (1, 2, 3) are tuned without a tuning device such as a series or parallel resonance circuit. The system is tuned by the fact that the imaginery inductive component of a radiation element (1) too long at a certain frequency is coupled by spacial approach with the imaginery capacitive component of a too short radiation element (2), those two components compensating mutually. Hence, the system is adapted to the impedance of the conductor by an additional conductor (10) which further makes accessible other frequency ranges such as for example 7 MHz.

Title: Measurement of asphalt concrete road surface temp. - by measuring temp. of air sucked through surface layer
Inventor: SESTOPALOV ALEKSANDR A
IPC: G01K1/16
Filed: 1980-12-10
Abstract: The method for measuring the temp. of an asphalt concrete road surface involves measuring the temp. of air which is used as a heat carrier to accurately transfer the measured temp. The arrangement contains a system enabling simplification in terms of operation and construction. Before the temp. is measured the air is filtered through the road surface. This is achieved by vacuum cleaning a section of the surface which is isolated from its surroundings. Air is passed through a hollow thermally insulated chamber (1) by a suction device (11) mounted in the top of the chamber. The suction device contains an impeller wheel (12) in the neck of the chamber. An alternative suction device is a piston vacuum pump.
