Title: Adaptive radio reception aerial system - has main reflector aerial and several reference radiators producing minimum sensitivity in noise source directions
Inventor: REITZIG RAFAEL DR
IPC: H01Q3/26
Filed: 1976-11-04
Abstract: The aerial system minimises noise interference signals originating from discrete directions. It consists of a number of radiators arranged in a group, and of a correlation an feed-back network for each radiator direction, controlling amplitudes and phases in the radiator group. These networks are provided between individual signal receiving radiators on one hand, and an output combining the signals on the other. One of the radiators is a sharply focussed scanning reflector aerial. The other radiators are reference radiators whose number corresponds to that of suppressable interference sources. The adaptive correlation and feedback network correlates only the levels of secondary lobes of the reflector aerial with the level of one or several reference aerials so that the resultant secondary lobe characteristic of the reflector aerial is so modified, that a level minimum appears in the direction(s) of noise sources.

Title: Sliding fire wall door for conveyor - has conveyor section passing through wall swung clear automatically as door closes
Inventor: STEINICKE ECKHARD
IPC: B65G43/00
Filed: 1978-04-11
Abstract: The opening in a fire wall through which a conveyor passes is sealed by a sliding fire door. the part of the conveyor which lies in the path of the fire door is detachable and is mounted on a lever arm which enables the detachable element to be swung away from the opening when the fire door is closed. The fire door and the element lever arm are mechanically linked together so that a movement of the fire door causes the rotating movement of the conveying element lever. The fire door consequently operates the lever so that the reliable removal of the conveying element is guaranteed. If the fire door is mounted vertically above its closed position, the downward movement of the fire door can be used to drive the conveyor element lever. The device guarantees a fire proof seal of an opening in a fire wall through which a conveyor passes whilst ensuring that the displaced conveyor element is accurately returned to its operating position when the fire door is opened.
