Title: Packaging system, esp. for brittle tubes or rods - shrink wraps items compactly to give the package strength and ensure protection against breakage
Inventor: LUENEBERG HARTMUT DR ING
IPC: B65B19/00
Filed: 1977-07-02
Abstract: Tubes or rods cut to the same length, are assembled into a package in which they lie as closely as possible against each other. The ends of this package at least, are enclosed in a wrapper of flexible material (pref. polyethylene) which fix the package at its predetermined density. The package obtained may then be stacked on a pallet with a large number of similar packages and fixed to it by a second wrapper of flexible material. The tubes or rods are of brittle material such as glass or ceramic and the package is pref. rectangular in section. During transport the items are kept as clean as when they were first produced and can be processed further without an intermediate operation. Packing papers and cartons are unnecessary. The packages contain 20% more tubes than the earlier ones of the same size.

Title: Hydraulic power generator working on low head - has hydraulic-pneumatic system to multiply force available at output
Inventor: WALLENDA ENGELBERT
IPC: F03B17/02
Filed: 1978-02-04
Abstract: Water enters a first container through an inlet and leaves it through an outlet having fallen through a small height. This raises a float within the container. The float compresses air against an upper section. This raises the upper section which lifts water into a second container. The water falling into the second container depresses a plunger which compresses air against a lower section. This in turn forces water from the bottom of this container into a third container. The water entering the third container raises a piston whose motion gives a useful mechanical output.

Title: VHF radio receiver with automatic tuning suppression - is operative only when decoded received regional code equals stored regional transmitter code
Inventor: STRAUSS KARL-PETER DIPL ING
IPC: H03J1/00
Filed: 1978-11-23
Abstract: TheThe VHF radio receiver has an extra memory storing the regional codes of transmitters. A regional-code decoder has its output compared with the code stored in the extra memory. This second comparator's output controls a gate between a first comparator and the automatic tuning circuit. The gate only passes a 'stop tuning' signal to the tuning circuit when the stored code is the same as the decoded code. Another memory stores the transmission frequencies of transmitters with regional codings, transmitters with no regional coding but the same broadcasting authority, and transmitters with the same or adjacent geographical locations. This memory is served by a third comparator.

Title: Applying protective coatings to workpieces, esp. to containers - where container is rotated and tilted while partly immersed in coating tank
Inventor: KRUSE KARL-HERMANN ING GRAD
IPC: B05C3/04
Filed: 1979-02-05
Abstract: The workpiece has an open interior, and is lowered into a tank contg. a coating material so the workpiece or container is partly immersed in the material. The container is then rotated, so the material is spread over its entire external and internal surfaces, followed by raising the container and continuing its rotation on a horizontal axis so the material in the container drains back into the tank. The pref. coating plant consists of a pair of overhead rails along which a trolley is driven. Each end of the trolley is fitted with guides for a vertically adjustable holder which projects downwards and ends in a universal joint carrying a U-shaped clamp. The two clamps fit diagonally on the ends of the container and are used to rotate the latter in the tank. The universal joints permit tilting of the container. The coating material may be a paint or a powder. The invention ensures the uniform distribution over the external and internal surfaces of the workpiece.
