Title: Large fuel tank level measurement device - has guide bush carrying folding floats sliding on vertical rotor
Inventor: SCHOESE WERNER
IPC: G01F23/68
Filed: 1979-10-12
Abstract: A device for measuring fluid level in large containers is esp. suitable for fuel dump tanks. A float with a central guide bush slides over approximately the entire possible fluid height of the tank on a rotor. The float position is converted into an electrical signal. It is easier and quicker to mount than conventional devices which require two operators to fit and remove. The improvement is achieved using fixings which do not significantly increase the production costs. The float consists of a number of float bodies distributed about the periphery of the guide bush to which they are linked. With a vertical tube position the float bodies hang down parallel to the longitudinal pipe axis when not immersed. When they are immersed they assume a horizontal position. The float bodies are each filled with a gas which is lighter than air.

Title: Playback device for recording discs - has probe with radial slide for automatic access to specified tracks
Inventor: KRAUSE FRANZ-EBERHARD DIPL ING
IPC: G11B27/30
Filed: 1980-06-27
Abstract: The device is esp. useful for image or sound recording discs and enables selection of individual tracks which are provided with addresses. The difference between a probe address (P) supplied from a probe (6) which is situated at any point on the track (21) and a desired address (x) is determined. The probe is moved radially by a distance corresp. to the difference (x-P) and then re-engaged. The direction of movement of the probe (6) can depend on the sign of the difference (x-P). The distance of the calculated radial movement as can deviate by a constant amount from the difference (x-P) such that the probe (6) is replaced onto the disc (1) shortly before the desired address (x). The signal play-back channel (8,10,11) is released when the probe (6) has reached the desired address (x). The play-back of a track is switched off by means of an identified reference character.

Title: Landing damper for parachute loads - has self erecting airbags with limited flow vent valves
Inventor: NOEHREN HUBERT
IPC: B64D1/14
Filed: 1980-06-28
Abstract: The parachute load landing damper has a self erecting airbag (14) under the load, to extend while the load is falling. On striking the ground air is expelled from the airbag via limited flow valves (25), through which the original air filling is taken during falling. A main damper (14) under the main part of the load and smaller dampers (15) under the edges, or wings, of the load provide maximum protection. The system does not require any gas bottles for inflation. A ballasted bottom in each airbag and an internal spring ensures simple erection. The dampers are fitted to aircraft dropped loads as well as recovery systems for spacecraft.

Title: Combined cigarette tip with water filter
Inventor: ZAJONZ ARNOLD
IPC: A24F1/30
Filed: 1981-01-22
Abstract: The combined cigarette tip with water filter filters the harmful substances contained in cigarette smoke in a natural way in the filter water. It can be designed in various sizes and shapes. The filter water can, if required, also be replaced by another liquid. In the exemplary embodiment illustrated in the accompanying drawing, the cigarette (item 1) is inserted into the filter body (item 2), whilst the filter tube (item 3) projects into the (possibly removable) filter base (item 4). The mouthpiece (item 5) adjoins the filter body. The normal enjoyment of smoking is further increased by the additional attraction of the rythmic bubbling of the water bubbles in the filter. <IMAGE>
