A method for cleaning a microporous, water-wettable, alcohol-insoluble, polyamide membrane used for cold beer filtration using a dilute, alkaline solution which is non-destructive to the membrane and the filtration equipment and which removes and/or de-absorbs and otherwise renders loaded proteins, polysaccharides and other biomolecules flushable from the membrane with water.

An induction melting vessel (10) comprises a refractory crucible (12) having an open top end (14) and a closed bottom end (16), with a substantially continuous side wall (20). A substantially continuous metallic shell (22) surrounds and generally conforms to the side wall (20) and extends for at least a majority of the height of the side wall from the bottom end to the top end. The shell has a bot...

"METHOD FOR TREATING AQEOUS STREAMS CONTAINING UNDESIRED AMOUNTS OF CYANIDE" A cyanide-containing aqueous stream is treated to reduce the cyanide concentration by oxidation of cyanide using oxygen as the oxidizing agent under mild reaction conditions in the presence of a metal chelate catalyst. Especiallyeffective chelates are metal phthalocyanines, particularly where the metal is vanadium or a me...

A cooking appliance has a heater for cooking, and a switch which generating an operational signal. The cooking appliance automatically turns off the heater a predetermined time after a last pressed switch, i.e., automatic power off function. A caution lamp indicates that the heater will automatically be turned off a minute prior to the automatic power off function. 14

The invention concerns an improvement to be introduced to continuous casting machines for thin flat parts (as in Fig. 1) in order to minimise the problems of containing the liquid metal due to wear, caused by reciprocating contact, of the contact surfaces between counter-rotating rollers 1 and 2 and corresponding side plates 5 and 6. The improvement consists in the fact that, at least in the areas...

In continuous metal casting machines for products of low thickness, a new dispenser of liquid metal into the ingot mould is introduced comprising a channel extending longitudinally inside the ingot mould and having a number of holes in the bottom. In this way non-uniform metal flow and temperature in the ingot mould and the consequent surface defects are reduced.

A device for full field sampling of endocervical cellular material of the squamo-columnar junction, the uterine cervix and the vaginal forks using a new design of two- lobed spatula for the purpose of preparing cytological preparations (Pap test) for the monitoring of cancer in women.
