Patent DE-2413009-A1 (DE)
Title: Filtering compensation of fundamental wave - is for irregular measurable variables caused by measurement process
Inventor: HEIDER HANS-JUERGEN
IPC: G01R17/00
Filed: 1974-03-18
Abstract: Several cascaded series-resonant circuits are stagger-tuned in their resonant range, so that the resulting filter curve shows the required bandwidth. Known combinations of series and parallel-resonant circuits are used for the filter. The width of the filter curve at otherwise identical attenuation behaviour with respect to the measurement signal spectrum is changed. Therefore, the disadvantages of the attenuation constant of the fundamental wave from the variation of the motor speed of the measuring machine are prevented. The frequency increment of the resonant range of several filters is known as stagger-tuned filter.

Title: Machine tool setting jig - has guide piece accommodating spring loaded mandrel and feeler needles in line
Inventor: STEINKE HERMANN O
IPC: B23Q17/22
Filed: 1974-09-20
Abstract: The jig enables the positioning of a machine spindle to be carried out in relation to marking-out lines on workpieces movable in two directions once clamped, and lockable in position. It is inserted in the machine spindle so that a line passing through the spindle axis and its two centre points automatically swings towards the marking-outline, reducing the acute angle between them to nil until they coincide. This setting operation is then repeated in a direction at right angles or inclined to the first one, whereupon the intersection is centre-punched or pilot drilled. The jig comprises a guide piece with three or more parallel apertures in line with each other. The larger central aperture acts as a bearing for the rotary positioning mandrel with centre point, which slides against spring action.

Title: Beverage can weakened opening - has wedge opening split open by pressure on sides closable again under elasticity
Inventor: GROSS GUENTHER H
Filed: 1975-06-27
Abstract: A small metal container such as a beer can (1) has a wedge shaped cross section. The flat top face (5) of the can forms a straight edge (6) with an inclined face (4) which is located on the thin end of the wedge. The edge (6) is perpendicular to the vertical walls (9) of the container. The metal can is produced by drawing process and the cover (2) is rolled on after filling. The metal thickness along the edge (6) is weakened so that it fails when a tensile stress is applied to it. This stress is produced by pressing the two adjacent parallel container walls together between two fingers until the can splits open. By releasing the clamping force, the elasticity of the metal returns the can to its original shape so that the gap along edge (6) is closed again.

Title: Gas turbine jet engine with outer combustion chamber - has auxiliary nozzles and combustion chamber between compressor and turbine
Inventor: VESTER GERHARD
IPC: F02C7/08
Filed: 1975-09-08
Abstract: Engine has an annular combustion chamber (2) surrounding the inner tube which contains the moving parts.
