Patent DE-2433116-A1 (DE)
Title: Lightweight rudder shaft for boat - with box cross section and internal rib reinforced flanges
Inventor: HARTMANN JAN DIPL ING
IPC: B63H25/38
Filed: 1974-07-10
Abstract: The rudder shaft is made up of a metal box section with square profile, which is reinforced by a pattern of internal ribs. The attachment bolt holes are provided by captive nuts welded between ribs at the upper and lower ends of the shaft. The ribs provide a secure mounting for the upper and lower fitting flanges.

Title: Reverse osmosis to separate tartar from wine - as filtered crystals from cooled osmotic concentrate
Inventor: RHEIN OTTO
IPC: C12G1/12
Filed: 1974-08-12
Abstract: Accelerated crystallisation process in which a solution is passed by a pump to one or more reverse osmosis modules in which a concentrate of super-satd. soln. is separated from a permeate. The concentrate enters a crystalliser to form crystals which are deposited in a filter from which filtrate flows on to be re-united with the permeate. If desired, the crystallisation can be further accelerated by diffusing a fluid of minute bubbles of inert gas, e.g. nitrogen, through the supersatd. soln.; alternatively, the supersatd. soln. can be subjected via immersed electrodes to an alternating current at about 50 to about 200 hertz. Accelerated crystal sepn. from a soln. esp. the removal of tartar as crystals from wine or other tartar-producing drinks. Rapid elimination of tartar in a continuous process which has no adverse effect on the flavour, appearance or other quality of a wine.

Title: Binder for incidently released aggressive liquids or oils - contg. granulated foundry pumice and slaked lime
Inventor: FUELLING WERNER
IPC: B01J19/06
Filed: 1974-11-22
Abstract: Binder for aggressive liquids (esp. acids) or oils incidentally spread on roads, industrial premises, etc., consists of foundry pumice sintered at 600-700 degrees C (pref. 675 degrees C) having a particle size of 0.5-3.5 mm, and contg. 5 wt. % of slaked lime.

Title: Unit monitoring system for cable TV equipment - has release of information from monitors determined by shared clock signal
Inventor: SCHUMANN ALFRED
IPC: H04B17/40
Filed: 1975-05-21
Abstract: The unit monitoring system, for vable television equipment, is capable of monitoring the operations of an almost unlimited number of units, e.g. amplifiers, and has monitors assigned to each unit to generate signals describing that unit's condition. All these monitors (9) transmit their condition information sequentially to the central control (2, 3) using the same carrier frequency. The release of information from the monitors is determined by a shared clock signal, and each monitor contains a pulse counter and a receiver for the synchronising clock signals from the central control. When the counter reaches a state corresponding specifically to that monitor, then that monitor releases its information.

Title: Fail safe extraction for sump fuel tank - with hollow sump and angled fuel drain into sump
Inventor: ANHEGGER SIGMUND
IPC: B60K15/077
Filed: 1975-09-05
Abstract: The bottom of the fuel tank has a hollow sump made from two identical half shells (8, 12) welded together at the seam to form a hollow shape. This is set into a hole in the tank bottom and sealed.
