Patent DE-2722882-A1 (DE)
Title: Compressive and tensile muscle training device - has endless cord around telescopic tube which houses compression spring
IPC: A63B21/00
Filed: 1977-05-20
Abstract: The muscle exerciser, which provides compressive and tensile training, consists of a hollow tube that locates a compression coil spring on each end. Each spring is contained in a sleeve which slides over the outside of the main tube. An internal step on the sleeve is retained by the flared tube end so that the tube and the sleeves remain assembled. A rope which surrounds both end sleeves can be pulled away from the tube, thus compressing the springs by applying a tensile force. By pushing the two end knobs together, compressive exercises are possible.

Title: Flameless atomic absorption spectroscopy calibration - evaporates and precipitates specimen on internal wall of cooled graphite tube by gas flow
Inventor: HUBER BERNHARD WERNER
IPC: G01N1/40
Filed: 1977-06-04
Abstract: In the flameless atomic absorption spectroscopy calibration process, an unknown substance is analysed in a graphite tube. The effect of the automation of other substances which will absorb the same spectral lines has been considerably reduced. The specimen is evaporated and precipitated on the internal wall of a graphite tube maintained at a lower temp. The sample is placed in a melting crucible (26) and heated to a temp. at which the unknown substance is volatile. The graphite tube (38) is held below this temp. A protective gas current is passed through the crucible and then conducted through the graphite tube to effect the precipitation.

Title: Air supply system to working positions - counteracts setting alterations by altering supply to traffic areas
Inventor: SCHROEDER DIETRICH ING GRAD
IPC: F24F7/10
Filed: 1979-05-02
Abstract: The system keeps the set air supply to individual working positions constant, particularly in a large office. A first system, typically a false ceiling, supplies air to the traffic areas and a second one to the working positions, the supply to each of the latter being individually adjustable from them. Both systems are supplied from a common source in a quantity independent of these individual settings. Any alteration in the quantity delivered to individual working positions is counterbalanced by one in that supplied by the first system.
