Abstract: ACTIVE ATTENUATION OF NOISE IN A CLOSED STRUCTURE            Abstract This invention is directed to a system for the active acoustic attenuation of noise produced in the interior of an enclosure by a source of noise which in one aspect comprises input sensing operable to sense the source noise to be atten-uated, cancelling news adapted to produce noise 180° out of phase with the source noise and error sensing means operable to sense the acoustic summation of the source noise and the noise produced by the cancelling means. The input sensing means, cancelling means and error sensing means are each preferably disposed at or immediately adjacent an area of high acoustic pressure within the enclosure.  The system further includes a second input sensing means disposed adjacent the source of noise, a second cancelling means adapted to introduce noise 180° out of phase with the source noise at a location at or immediately adjacent the enclosure wall and second error sensing means disposed in the interior of the enclosure.  Each set of input sensing means, cancelling means and error sensing means are adapted to be connected to an electronic controller means operable to process signals from the input sensing means, produce outputs to drive the cancelling means for the introduc-tion of cancelling sound waves into the enclosure for combina-tion with the source sound waves, and then adjust such outputs based on signals received from the error sensing means.

Abstract: ABSTRACT OF THE DISCLOSURE          There is disclosed a process for the polymerization of a non-air-curing mono-ethylenically unsaturated free-radical polymerizable monomer in which an oxidative prepolymerizate is incorporated into the monomer.  The prepolymerizate is an oxidatively polymerizable compound in which there are at least two unsaturations which are each .beta.,.gamma. to oxygen or sulfur which is employed in an amount of 1 - 200 parts by weight of the prepolymerizate per mole of non-air-curing monomer, and is of the formula   where R1 is a radical characterized by a molecular weight less than about 2000, obtained by removal of active hydrogen from an active hydrogen compound selected from the group consisting of water, alcohols, thiols, carboxylic acids, carboxylic amides, and amines, where the functionality of R1 is n, and is in the range of 1 to 10, where R2 is selected from the group consisting of hydrogen and C1 to C10 organic radicals, where E is a moiety containing a radical having an activated olefinic unsaturation .beta.,.gamma. to the activating group and is present in sufficient amount to provide a  .beta.,.gamma. -unsaturation equivalent of less than about 250, where m is the average number of E moieties in the n segments of the structure and where the product of m and n is in the range of about 4 to about 60.  Compositions are also disclosed of the oxidative prepolymerizate described above together with the polymerizable monomer.  The resulting products formed after polymerization have a wide field of utility in adhesives, moldings, casting operations and the like.  With the present development, since the oxidative prepolymerizate and the monomer copolymerize, varying of the properties of the final product can be readily achieved.

Abstract: ELECTRONIC CONTROL SYSTEM FOR A CARDIAC PROSTHESIS       ABSTRACT        An electronic control system for controlling the operation of a cardiac prosthesis is disclosed. The cardiac prosthesis includes domi-nant and subordinate ventricles which receive blood in response to body requirements and an actuation device coupled to the ventricles for ejecting blood from the ventricles. The electronic control system includes sensing devices to determine the volume of blood in the ven-tricles as a function of time. A control device, which in the pre-ferred embodiment is a programmed microcomputer, includes a clock controller which first determines the filling flow rates of the ventricles from the volume information from the sensing devices. The ventricle with the greatest filling flow rate is selected as the dominant ventri-cle. The clock controller then adjusts the heart rate of the cardiac prosthesis as a function of the filling flow rate of the dominant ven-tricle to allow just enough time for the dominant ventricle to fill completely. The control device further includes first and second ejection rate controllers which generate control signals to adjust the ejection rates of the dominant and subordinate ventricles in accordance with the adjusted heart rate so the dominant and subordinate ventricles can eject all blood in the time allowed by the adjusted heart rate.          The control signals are supplied to pump motors to control the opera-tion of pump motors which in turn drive the actuation device to eject blood from the ventricles.

Abstract: ABSTRACT     A wide variety of drinks and foods, such as fruit wine, herb tea, a medical decoction, yogurt, fermented soy-beans and hot-spring eggs, are produced by heating the raw materials to a temperature of about 60°C to 100°C in a vessel, and holding that temperature for a specific length of time, i.e. 3-24 hours for maturation.  When producing drinks, it is effective to subject them to a weak vibration, wave motion, forced convection, or stirring force.  The method enables the quick production of any desired food or drink in any desired quantity without causing any appreciable reduction in the alcoholic content of, for example, fruit wine.
