Patent DE-2526826-A1 (DE)
Title: Deodorising of vegetable oils by sepn. of components fractionally - from vapour stream using water injection to cause progressive temp. drops
Inventor: SCHUMACHER HEINZ
IPC: C11B3/14
Filed: 1975-06-16
Abstract: Process described is for separating entrained components of differing boiling pts. from a gaseous mixture of them. A vapour such as steam is used as the entrainment agent. The gas mixture is passed through a series of separators in each of which a controlled temp. drop is induced by injection of water as a spray. The extent of the temp. drop is controlled by metering the water flow. Pref in a first separator of drop of 50 degrees C from 170 degrees to 120 degrees C occurs. In a second separator a 60 degrees C drop from 120 degrees to 60 degrees C is made. Used for deodorising edible oils, where valuable fatty acids are present in the entrained vapours. Existing processes have the problem of high installation cost and unsatisfactory separation. In some instances on neutralisation, fatty acids are present in the soaps so formed. The system described permits separation into a pure and impure fractions with pure water vapour as the final product. this being fed to a barometric condenser system.

Title: Electrically operated pot scourer for saucepans etc - comprises oscillating cleaning head attached to fixed rigid or flexible spindle
Inventor: NIDA FREDERICK CHARLES VON
IPC: A47L17/04
Filed: 1975-07-25
Abstract: The motorised pot scourer comprises an electric motor (8) mounted on a holder (20) and has a rotating output shaft coupled with the spindle (7) of a cleaning head (6) by means of lever and transmission gearing (9, 10) which sets the cleaning head in vibration. The cleaning head spindle (7) can be basically rigid and is mounted on the holder (20) so that when the latter is fixed the spindle projects downwards to support the cleaning head (6) at the lower end although it is possible for the spindle to be flexible and provided with a handle to allow the cleaning head to be guided manually round the inside of the pans etc. To protect the saucepans etc and to provide for effective removal of burnt-on deposits it is preferable for the cleaning head to be driven in either oscillation or alternate rotation to prevent excessive centrifugal forces developing.

Title: Electronic gaming dice with delayed indication - has extra key to allow delay to be reduced or eliminated when desired
Inventor: PETERREINS MANFRED RUDOLF
IPC: A63F9/04
Filed: 1975-10-15
Abstract: The original design was meant to eliminate the possibility of cheating. The player pressed a switched to start a six-position electronic ring counter and to sound a signal. Releasing the switch initiated a delay, only at the end of which was the result displayed. It is now found that the delay can seem to dissociate the player's action too strongly from its result. An extra key is added to the circuit, to make it possible to terminate the delay prematurely, but possibly after a brief min. time. The new key can be cominbed in one unit with the player's switch.
