Title: Gas filter bags back flushed with moving nozzle - with regulated return to filtering state to prevent shaking of bags
Inventor: MARGRAF ADOLF DIPL ING
IPC: B01D50/00
Filed: 1974-07-17
Abstract: A gas filter with inward flow through the filter bags has a back-flushing air nozzle (elongated nozzle) which travels to each filter bag in turn and is used to inject a pulse of compressed air into the bag, thus inflating it and blowing off the dust from the outside. This nozzle can be connected alternately to the air blower, and to the clean gas side, to draw the filter bag back onto its internal supporting frame. The duct connecting the nozzle to the clean gas side is of much smaller cross-section than the duct connecting the blower to the nozzle. The flap-valve which effects the change-over can be used for regulating the pressurised period and suction period for the nozzle quite independently of each other.

Title: Drying method for programmed dish washing machine - uses heating air circulated inside, then mixed with cold air after final wash
Inventor: SCHAEFER ERHARD
IPC: A47L15/48
Filed: 1974-08-23
Abstract: The programmed dish washing machine is operated so that after the main washing stage, the contents are rinsed with cold water and washing fluid and is then heated by radiation or convection for a sufficient time for the dishes to be dried, not by the residual heat of the dishes. During this heating stage, the air inside the chamber is circulated by e.g. a blower, and this air may also be mixed with fresh air, admitted through flaps. This air is passed over a cooling surface e.g. curtain of cold water, during which time the heating is interrupted. The heating air supply is controlled in proportion to time, temperature and/or humidity.

Title: PCM transmission system using codewords for difference values - has each codeword used for at least two successive difference values
Inventor: LIPPMANN REINER DIPL ING
IPC: H04L1/00
Filed: 1974-12-30
Abstract: The transmission system uses binary codewords for representing difference values, at least each two successive difference values transmitted using a common codeword. The classification of the codewords for the possible combinations of difference values is such that a bit error in a codeword gives a combination of difference values of the sum of which differs from that of the correct combination of values. Pref. to reduce errors the combinations of difference values are converted into different combinations, to which the codewords correspond, with a free codeword selected so that upon an error in the codeword of a frequently used combination the free codeword is obtained, which indicates the frequently used combination.

Title: Oil contaminated ground treatment - by mixing with hot water in screw feed drum and separating in settling basin
Inventor: HEIDENREICH PAUL
IPC: B03B9/02
Filed: 1975-07-16
Abstract: Earth which has been badly contaminated by fuel oil is washed with hot water at 60-90 degrees C and a solvent by mixing it in a screw conveyor drum, followed by separating from the cleaning medium, containing the contaminants, in a settling basin. Dissolved oil and other soluble contaminants are recovered by filtering, centrifuging, precipitation or neutralisation. The process creates less difficulties than the provision of special waste disposal dumps which are subject to clean water regulations. Combustion leaves many pollutants in the residue andis an expensive method of disposal.
