Abstract: A method for distilling a fluid which is useful, for instance, in eliminating salt from brackish and/or sea water includes percolating films on plates with multiple effects having several evaporating zones and condensation zones. The evaporation zones (EVAP) and the condensation zones (COND) are vertically arranged. The liquid to be distilled emerges in the top part of the evaporation zone (EVAP). The vapors produced in the evaporation zone (EVAP) are horizontally transferred into the condensation zone (COND) through a communicating connection. The condensed liquid percolates vertically along the walls of the condensation zone and is evacuated from the lower part of the condensation zone. A distilling plant is also provided for implementing the distilling method, and includes plural cascades made up of elementary cells alternatingly assembled in thermal series.

Abstract: Enzyme-containing polymers are prepared by an anhydrous process of direct reaction of an enzyme in organic solution with crosslinking organic compounds having terminal reactive groups. In a first step, the enzyme is reacted in an organic solvent with a bifunctional monomer such as p-phenylene diisocyanate, 4-methyl-m-phenylene diisocyanate or 4,4'-methylenebisphenyl diisocyanate, and in a second step a bifunctional amine such as N-phenylethylenediamine, 1,6-diaminohexane, N,N'-diethyl-ethylenediamine or 1,4-diaminobutane is added. The enzyme-containing polymers are used as catalysts in chemical reactions such as acylation or enantioselective acylation of alcohols.

Abstract: A snack dispenser consists of a series of tiers stacked to resemble a wedding cake. Each tier includes a trough divided into slots. A snack may be placed into each slot. The front of each slot is transparent. The troughs or trays are mounted on a rotatable carousel. The carousel is covered with a backshell and a transparent front shell. The front shell has transparent doors therein. By inserting a proper amount of money and aligning the carousel so that the desired snack is beneath a door; the door may be opened and the customer may withdraw his snack from that slot. The opening of the door blocks the rotation of the carousel, blocks the opening of the remaining doors, and also resets or cancels the credit of the coins inserted. When the single door is closed again, all doors will be blocked so that a person can not again open a door until proper coins are inserted. To service the dispenser the front shell is removed. A segment of all tiers is removed. All segments are removed and collapsed from stacked position to flat position. Replenished flat segments are removed from a box, telescoped, and placed on the dispenser. The removed flat segments are placed in the box and the front shell replaced.

Abstract: A color image is printed onto a first substrate, which acts as an intermediate medium, using lithography, intaglio, gravure, relief printing or other printing process which uses plates. The image is subsequently transferred from the intermediate medium to a final substrate, which may be a textile of natural fabric, such as cotton. Bonding and/or crosslinking of the color images are provided by the reaction between compounds selected from each of two chemical groups. The first group comprises compounds with functional groups capable of reacting with active hydrogen, such as isocyanate or epoxy groups. The second group comprises compounds with functional groups containing active hydrogen, or compounds with functional groups containing active hydrogen after a conversion process. The functional groups of one or both reactive chemical groups are protected either by chemical blocking with blocking agents or by physical barrier such as encapsulating agents. The blocking agents are removed by the application of heat during the transfer of the image from the first substrate to the final substrate.

Abstract: Det er vist en væsketrykkdrevet, høyfrekvent perkusjonshammer for boring i harde formasjoner. Perkusjonshammerens hammerstempel (20) har en langsgående relativt stor boring (41) som gir minimal strømningsmotstand for en borevæske gjennom boringen (41) under hammerstempelets (20) returslag. Boringen (41) er lukkbar i oppstrømsretningen av en ventilplugg (23) som følger hammerstempelet (20) under slaget. Ventilpluggen (23) er styrt av en relativt lang og slank ventilstamme (49) som mekanisk er i stand til å stoppe ventilpluggen (23) ved om lag 75 % av hammerstempelets (20) fulle slaglengde og skiller den fra en setetetning (40). Dermed åpner boringen slik at borevæsken kan strømme gjennom, og ventilstammens (49) iboende strekkfjæregenskaper returnerer ventilpluggen (23) så raskt at det blir god gjennomstrømning under hammerstempelets (20) retur.
