Title: Test method for stud welding pistol using electric arc - ensures that welding current pulse occurs while stud is lifted off workpiece
Inventor: NETZSCH HERMANN
IPC: B23K9/20
Filed: 1978-01-03
Abstract: At the start of the test procedure, an electric starting signal (S1) is fed to a timer and, when the stud is pressed against a test piece, a second signal (S2) is generated and also fed to the timer, which measures and displays the time interval between the two signals. When testing pistols without a welding procedure, S1 is pref. obtd. by switching off the electromagnet used to lift the stud off the test piece, whereas S2 is obtd. when the stud is pressed onto the test piece by a spring. When the test method is used during welding operations, S1 is obtd. when the welding current exceeds a threshold value; whereas S2 is obtd. when the stud enters the molten weld pool on the workpiece. Optimum adjustment of arc welding current and time during stud welding is obtd.

Title: Isolated HT voltage and current meter - uses photoelectric or high tension harmonic charged rechargeable supply battery
Inventor: SCHRAEDER ALFONS DIPL ING
IPC: G01R15/22
Filed: 1978-07-06

Title: Sampling device for granular material - uses successive separation stages to reduce size of final sample
Inventor: KNAPPE RUDOLF
IPC: G01N1/20
Filed: 1979-12-24
Abstract: The device comprises a multi-stage rotary sample distributor, each individual stage comprising a number of funnels with the excess material from each stage forwarded on. The outermost of each of two interfitting funnels in each stage has its outlet (14) fed to an adjustable vibratory conveyor (300) which supplies it to the rotary input device (326) for the subsequent stage. The device is used for granular material with a particle size of between 0.1 and 4 mm and allows the size of sample required to be reduced relative to a sampling device without separation by a ratio of 100:1.5. The size of the final sample depends on the number of successive stages employed its composition corresponding exactly to that of the material stream being sampled, without undesirable separation of the different particle sizes.

Title: Variable pitch aircraft propeller - has blade roots turned by flyweight operated cam drive
Inventor: WANITSCHEK HERBERT
IPC: B64C11/34
Filed: 1980-01-08
Abstract: The automatic pitch control for an airscrew has the blade roots mounted in swivel bearings in the hub and coupled to drive cams by angled slots and drive levers. The cams are driven by flyweights (3) or are cut on the flyweights themselves. The blades start to feather as the speed increases to limit the torque. The flyweights operate against return springs so that the blades (1) are set a maximum pitch for startinq. As the aircraft gains speed the screw can turn faster with less drag. The device can be applied to model aircraft and is simple to make. It reduces fuel use and noise at lower, starting speeds, and saves fuel at high speed flight.
