Inventor: C TERRELL ROSS
IPC: C07C43/12
Filed: 1970-11-27
Abstract: Inhalation anaesthetic compsn. contains (a) a life-maintaining amount of oxygen and (b) a cpd. CF2ClOCF2-CHFBr (Ia) or CHF2OCF2cfbrCl (Ib) in an amount suitable for causing anaesthesia. (Ia) and (Ib) are prepd. by chlorinating CH3OCF2CHFBr to give CCl3OCF2CHFBr or CHCl2OCF2CFClBr and fluorinating this to give (Ia) or (Ib).

Title: Filled coating prodn - by precipitating the binder from soln by addition of water
IPC: B05D7/24
Filed: 1970-12-23
Abstract: Coverings for e.g. sport tracks, lining plates, drainage elements, soil-reinforcing coatings etc., produced from granular or fibrous, natural or synthetic fillers and polymeric, synthetic binders are improved by using a binder dissolved in an organic solvent which is completely miscible with water; applying the compsn. layerwise; adding water to precipitate the binder; and removing the solvent-water mixture. The separation of the polymer from the solvent and the removal of the latter occurs easier and more rapidly than by evaporation at ambient temps. The method can be used at temps. down to 0 degrees C.

Title: Filter cleaning system - partic. for porous or sieve type filter aid-coated filter elements
Inventor: TIEDEMANN WOLFGANG OTTO
IPC: B01D37/04
Filed: 1973-08-31
Abstract: Cleaning of the sieve element in a liquid filter of the known type consisting of a container subdivided by a partition into inlet and outlet chambers and having a number of preferably rod-shaped sieve elements installed in the inlet chamber and mounted on the partition, by (a) providing a cushion in the inlet chamber (b) completely shutting-off the feed and discharge from the container, (c) blowing compressed air into the outlet chamber momentarily, so that for a short time liquid flows from this trhough the sieve element into the inlet chamber, thereby causing the filter cake formed during filtration to be released from the sieve element and the air cushion to be compressed by the increased amount of liquid in the inlet chambers, (d) directly there-after releasing the air injected from the outlet chamber, whereby the air cushion in the inlet chamber expands and produces a short term flow of liquid from that chamber into the outlet chamber, which breaks up the filter cake released from the sieve elements. More especially, the steps (a)-(d) are repeated several times. Cleaning of the filter elements can be carried out without discharging liquid from the filter, by a rapid and easily carried out method which can be repeated at closely following times as soon as the flow resistance becomes too great.

Title: Pulsed arc welding power system - with thyristor shunting smoothing choke
Inventor: BOGDANOW GEORGIJ JAKOWLEWITSCH
IPC: B23K9/09
Filed: 1973-11-16
Abstract: The welding current for a pulped arc welding plant is shaped by a rectifier and a choke to level out current pulsations. A thyristor is arranged in parallel to the choke and bypasses this choke is a selected pulsation period of the rectified voltage with a delay. This requires only one source of supply and eliminates the dips in the basic current curve after a pulse has passed. Current, pulse amplitude, and pulse duration can be adjusted separately within the wide limits. The weight, dimensions and cost are much reduced (by 50-80%).
