Patent DE-1924527-A1 (DE)
Title: Separating paint and water
IPC: C02F9/00
Filed: 1969-05-14
Abstract: Intensive mixing by air-injection of a paint-containing water which has been treated with a coagulating agent causes the formation of a paint-foam which can be separated from the water by overflowing. The process is particularly suited for the wash water after electro-painting processes, which normally contains 0.1 to 0.3% of paint in water. After treatment with coagulation agents the paint articles are still difficult to separate. This process separates the paint into another phase which can easily be separated without needing a long retention time. If necessary the water can be further purified by passing through a coke filter before discharge.

Patent DE-2008442-A1 (DE)
Title: Polyvinyl butyral sheets with roughened surfaces
IPC: B29C59/04
Filed: 1970-02-24
Abstract: The surfaces of plasticized polyvinyl-butyral are roughened simultaneously by passage through a cold bath between rubber coated rolls at a temperature of between (t +5) degrees adn 140 degrees, pref. 85-100 degrees C, where t is the minimum temperature at which the sheet can be embossed between calendar rolls.

Title: Load cell load suspension device - has wire guide ropes to prevent horizontal displacement giving erroneous readings
Inventor: FISCHER KARL
IPC: G01G3/12
Filed: 1973-08-20

Title: Computer memory unit for data and instructions - has multi-section memory in which information can be selectively recorded
Inventor: JANAK MILOSLAV DIPL ING
IPC: G06F12/04
Filed: 1973-12-08
Abstract: A circuit is used for the transfer of data from a memory to a computer unit, in which the memory is controlled by addresses, and the information is fed in and extracted n bytes. The memory may be split into 2n blocks and during the recording process the last n bit places of the last address byte is fed to a decoder (DC) by means of which all or only a single one of the blocks is selected, and in reading out the data the last n bit places are used to control a multiplexer to select the addressed contents of all the blocks or a selected block. The arrangement facilitates the use of a single memory for data and instructions having very different word-lengths.
