Title: Dosing device to treat water with soluble disinfectant - in buoyant casing which floats to surface when sufficient disinfectant has been dissolved
IPC: C02F1/68
Filed: 1985-04-04
Abstract: The device is of the type which comprises a casing which is loaded with disinfectant and then immersed in water to be treated. the casing has perforations to allow water to circulate through the case and progressively dissolve the disinfectant. The casing is made now in two sections of which one section has a cavity for loading with disinfectant. This cavity enclosure can be readily provided with perforations to allow water to circulate in contact with the disinfectant. - The second section of the casing comprises a float of which the buoyancy is insufficient to prevent the casing from sinking in water when the first section cavity is fully charged with disinfectant. The buoyancy of the float will however, bring the casing to the surface when a predetermine wt. of disinfectant has been dissolved from the cavity. - Pref. the buoyancy float section employs an air chamber as a float. The casing is made of thermally weldable plastic. The disinfectant cavity enclosure has external lugs. etc. which can easily be cut off to allow water to reach the disinfectant.

Abstract: METHOD FOR THE PURIFICATION OF WASTE WATER                  ABSTRACT OF THE DISCLOSURE  Effluent is removed from water by treating the effluent containing water with an enzyme of a microorganism having an aqueous ambience and/or an enzyme of the type employed in detergent preparations.  Previous analytic studies of the ambience of aqueous environments have shown the presence of enzymes therein.  However, it was heretofore unknown that any of these enzymes could be employed for purifying water.  Micro-organisms which have an aqueous ambience are generally a source of the enzymes within the scope of this invention.  Preferably, microorganisms whose aqueous ambience is polluted are employed for obtaining the enzymes, and particularly preferred enzymes are derived from microorganisms which thrive in the water which is to be purified.  A particularly suitable enzyme is, or instance, obtained from the microorganisms which are employed in conventional activated sludge and trickling filter methods to biologically purify water.  Quite unexpectedly it has been found that enzymes produced by these microorganisms, rather than the microorganisms themselves, may be employed to purify effluent containing water.  The enzyme producing microorganisms within the scope of this invention are not purestrains; they are mixed populations, such as usually occur in bodies of water, particularly in effluent containing water.

Abstract: ABSTRACT OF THE DISCLOSURE         Increased sensitization of liquid crystalline devices utilizing current flow to provide a change in optical characteristics is provided by sandwiching a photoconductive layer between an insulating layer and a liquid crystalline layer wherein all three layers are placed between two electrodes, the thickness ratio of the photoconductive layer to the insulating layer is at least about 10 to 1.  The sandwich device is utilized in an imaging method wherein an electrical potential is applied across said device, a bias or sensitizing light is utilized to bring the device up to the threshold for gain photocurrent and then removed, and wherein a subsequent light is utilized to gate or initiate gain photocurrent.  Alternatively the biasing light may be in imagewise configuration which forms a latent image in which cast the subsequent light can be a uniform exposure which gates the gain photocurrent, thereby developing the latent image.

Uniform initial preload tension can be applied to the key arms by a slotted member which engages the ends of the key arms remote from the cantilever points.  Non-uniform preload tension can be achieved by varying the height of some slots of the slotted member or by varying the height of the key arms at the ends thereof remote from the cantilever points.          Adjustment of the preload tension can be achieved by an eccen-tric positioned adjacent the cantilever points.
