Title: Method for producing nanocapsules with cross-linked protein-based walls, nanocapsules thereby obtained, and cosmetic, pharmaceutical and food compositions using same
Inventor: PERRIER ERIC
IPC: A23L1/00
Filed: 1992-10-27
Abstract: ABSTRACT OF THE DISCLOSURE         A method for producing nanocapsules with cross-linked protein-based walls, comprising preparing emul-sions of said proteins and crosslinking these with a crosslinking agent having reactive groups which react with the reactive groups of said proteins, particularly acylatable groups, to cause an interfaced crosslinking reaction  between  the  proteins  and  the  crosslinking agent, and thereby form capsules with walls based on the proteins crosslinked by the crosslinking agent.  A fine emulsion of said proteins is prepared by adjusting the surface tension of the various liquid phases.  Bio-compatible   and  biodegradable nanocapsules  having improved controlled release are thereby obtained.    Figure 1.

Inventor: CHIKAMICHI SHOICHI
IPC: G03F5/00
Filed: 1994-06-20
Abstract: Mask patterns and thire exposure times are stored in a memory within a controller. The controller transfers the mask pattern to a memory in the liquid crystal controller. The mask pattern stored in the memory is displayed on the matrix liquid crystal display element. The controller transfers the next mask pattern to memory after the elapse of exposure time. By this exposure apparatus, a plurality of mask patterns is exposed on a photosensitive material. The exposure time of each portion of the photosensitive material is adjusted in three or more grades by exposing a plurality of mask patterns sequentially. If the photosensitive material is positive, the film thickness becomes low in a portion which has a long exposure time and high in a portion which has a short exposure time. A combination of a plurality of mask patterns enables the section of the photosensitive material to be formed into a desired shape.

Abstract: A cellular telephone subscriber who wishes directory assist nce services is connected in the conventional manner to an operator who identifies a destination teleptone number desired by the subscriber-As in the prior art, the operator then initiates a call con~~cting the subscriber to the destination telephone number. However, rather than dropping all further involvement with the call, the preferred embodiment of the present invention continually monitors the connection thereby established for a predetermined DTMF signal issued by the customer, such as that obtained by pressing the "*" button. If such a signal is detected, the customer is transferred back to a directory assistance operator, who can then provide whatever further assistance is needed (e.g. redialing a busy number, or providing further directory assistance).      Billing information for the calls originated by the directory assistance operator on the subscriber's behalf is logged in a database at the directory assistance center. This data is thereafter provided to the cellular carrier, permitting it to bill the subscriber for calls originated by the directory assistance operator.

Title: Aircraft anti-icing fluids thickened by associative polymers
Inventor: JENKINS RICHARD D
IPC: C08L71/02
Filed: 1993-05-24
Abstract: An anti-icing fluid suitable for ground treatment of aircraft, being a glycol-based, aqueous solution containing a hydrophobe-bearing, macromonomer-containing polymer thickener in an amount of less than about 5 weight %. Thickening occurs predominantly by association among hydrophobe groups. Thickening may be enhanced by addition of a surfactant or other materials which act as co-thickeners. Use of this thickened fluid does not adversely affect airfoil lift characteristics during takeoff, because the fluid exhibits shear thinning and readily flows off the aircraft surfaces when exposed to wind shear during the air-craft's takeoff run.

Patent CA-2139934-A1 (CA)
Inventor: CHRISTENSEN RONALD J
IPC: C02F1/467
Filed: 1993-07-20
Abstract: Water in a process water system, such as a cooling tower or pulp and paper processing plant, is treated to destroy biological microorganisms by diverting the portion of the water flowing through the system to a side stream. In the side stream, chemicals are added such as halide ions or sodium chlorite. The water is then passed through an electrolysis unit or a UV radiation unit to oxidize the precursor to form an active oxidant. Advantageously, the pH of the side stream can be lowered to significantly improve the oxidization of the halide ions. When a very small portion of the flow rate is passing through the side stream, the acid added does not significantly alter the pH of the entire system. In a preferred embodiment, the acid added is phosphonic acid which acts as an antiscalant. Also included in the present invention is a method to inject oxidant precursors into a process water system through an oxidant generation station.
