Abstract: BUILT NONAQUEOUS LIQUID NONIONIC LAUNDRY DETERGENT COMPOSITION        CONTAINING HEXYLENE GLYCOL AND METHOD OF USE               ABSTRACT OF THE DISCLOSURE     The anti-gel and dispersibility properties of a nonaqueous liquid nonionic surfactant laundry detergent composition are improved by the addition of hexylene glycol to the composition. The addition of hexylene glycol reduces the plastic viscosity of the composition with little or no adverse affect on yield stress value of the composition or adverse affect on the physical stability of the composition. The addition of hexylene glycol and propylene carbonate to the nonionic surfactant composition substantially reduces the apparent viscosity of the composition and substantially improves the dispersibility of the composition.

Abstract: PHN11970                                                 12.10.1987 ABSTRACT Device for and method of subtraction imaging with reduction of motion artefacts.     Subtraction images formed by digital subtraction angiography contain artefacts due to the motions of the patient. This motion disturbs the condition imposed for subtraction imaging that only the introduced contrast medium is displaced and that the remainder must remain stationary. For example, when ribs of the patient have moved, due to respiration, between the formation of the first image and the second image, this motion will appear as undesirable information (the extent of the motion of the ribs) in the subtraction image. It is proposed to deform one of the images locally so that the motion of the parts which should remain stationary is compensated for. By subtracting the locally deformed image from the other image, a subtraction image will be obtained which is substantially free from motion artefacts and which contains only the information of the moving contrast medium. To achieve this, a shift vector is determined for various pixels and a reliability criterion is calculated for each direction component of said shift vector.

Granted: 1993-01-05
Abstract: ABSTRACT            An oral composition which is adapted to be dispersed in an aqueous carrier substantially immediately prior to administration comprises a multiplicity of particles comprising an active substance, the parti-cles being combined with one or more gelling or swelling agents capable of forming a viscous medium around the particles in an aqueous carrier as well as being provided with a masking surface layer when dispersed in the aqueous carrier. This serves to mask un-even surfaces on the particles and prevent them from adhering to oral mucosa when the composition is ingested and thus makes it easier to administer large dosages of an active substance. The masking surface layer is preferably provided by an increased viscosity of the viscous medium in the immediate vicinity of the particles relative to the viscosity of the surrounding aqueous carrier.          A ready-to-use composition is prepared by mixing the composition with an aqueous carrier substantially immediately prior to administration of the composition.            KBM/NO/43/PA26152E/07.03.88

Abstract: HYBRID ELECTRONIC RADIO REPEATER                     ABSTRACT      An improved hybrid electronic radio repeater comprising an antenna means for receiving a select, narrow frequency band of radio wave signals, the radio wave signal(s) being transmitted from discrete sources wherein the radio wave signals contain source,  status and control  information.  A radio frequency amplifier means filters and amplifies the radio signals and passes them to a mixing means. The mixing means, including a local oscillator means, combines the radio frequency signals with the local oscillator signals to produce intermediate frequency signals. The intermediate frequency signals are narrow filtered causing tuning by local oscillator tuning means. An intermediate frequency amplifier means detects and amplifies the IF signals and generates a signal strength level indication in response thereto. A control means, the control means being an intelligent unit capable of discerning information and generating responses thereto, monitors the signal strength level indications and also initiates the tuning voltage level of said narrow frequency band local oscillator tuning, for the presence of select radio wave signals, the control means tuning the hybrid radio repeater in response to the presence of the select signals.

Abstract: ABSTRACT        A method for producing a reinforced block material of a crystalline  material such as a metal or the like.     Has enabled the block-like molding of a reinforced material of the crystalline material which has been able to be formed hitherto in fiber-like or film-like shape only by making it amorphous or crystallized in a miniaturised grain structure.          Miniaturising the crystals of the crystalline material intends to reinforce the material by rapidly cooling the material in a molten state, and the same time, by giving large deformation by use of less deformation energy, and together with that, the production procedure is simplified by enabling the molding of the material to a block-like shape to make the lowering of the production cost and to enable the realization of the application to a molded article.
