Abstract: ABSTRACT OF THE DISCOSURE         Tap water is ozonized, using an electro-lytic cell provided with a solid electrolyte, by first dividing the freshwater stream into a main-stream and a sidestream and only feeding the latter via a water-softening unit to the electrolytic cell. The ozonized sidestream is recombined with the main-stream in the mixer.  The fractional rate of water of the sidestream is advantageously 0.5 to 3% by volume of that of the freshwater stream.

Abstract: BIVENTRICULAR CIRCULATORY  ASSIST SYSTEM        A biventricular circulatory support system for a human patient is described.  A mechanical first pump for assuming at least a part of the pumping load of the patient's left ventricle is implanted in the patient. A second pump for assuming at least a part of the pumping load of the patient's right ventricle is also implanted.  The second pump includes a surgically prepared skeletal muscle pedicle with nerves and blood supply substantially intact.  The muscle pedicle is applied directly to the right ventrical or is applied to an artificial pump sac.  Electrical signals are applied to the first and second pumps as appropriate to cause pumping action in a predetermined relationship.

Abstract: ABSTRACT            The invention concerns a process for the production of coarse scrubbing aggregates of TiO2 particles by vapour phase oxidation of titanium tetrachloride, the particle aggregates of sizes above 0.15 mm being separated from the TiO2 fines by the wet route on a moved screen, calcined and returned to the process. In a preferred embodiment of the process, the titanium dioxide prior to calcination is admixed with 0.01 to 0.3 % by weight alkaline hydroxides (related to anhydrous TiO2), hard particle aggregates of sizes between 0.2 and 2.0 mm being generated that are returned to the hot reaction mixture and used for the prevention of deposit formation on the surfaces of the heat exchanger.          The process can be carried through in such a way that the quantities of coarse scrubbing TiO2 aggregates per unit of time consumed by abrasion and newly formed by sintering are equal, their percentages in recycling TiO2 thus remaining constant which simplifies the TiO2 production process.

Abstract: NOVEL CARBON FIBRILS, METHOD FOR PRODUCING SAME, AND COMPOSITION CONTAINING SAME          AABSTRACT OF THE DISCLOSURE          This invention concerns a discrete carbon fibril char-acterized by a substantially constant diameter between about 3.5 and about 70 nanometers, length greater than about 5  times the  diameter and less than about 100 times the diameter, an outer region of multiple essen-tially continuous layers of ordered carbon atoms and a distinct inner core region.  The invention further con-cerns a plurality of such fibrils.          The fibrils of this invention may be produced by con-tacting for  an appropriate  period of  time and at a suitable pressure a suitable metal-containing particle with a suitable gaseous, carbon-containing compound, at a temperature between about 850°C and 1200°C.  or by treating  discrete  carbon fibrils, characterized by a length  greater  than  about  100  times  the diameter. Carbon fibrils may  also be  continuously  produced by continuously contacting for  an appropriate period of time at suitable conditions.          Another aspect of the invention concerns a composition of matter comprising a carbon fiber or a carbon plate and a plurality of fibrils.          Carbon fibrils and compositions of matter  comprising carbon fibrils are useful in composites having a matrix of e.g., an organic polymer, an inorganic polymer or a metal.   In specific embodiments,  the fibrils or the compositions  of  matter  may  be  used  to  reinforce  a structural  material,  to  enhance  the  electrical  or thermal  conductivity  of  a material,  to increase the surface area of  an electrode  or capacitor plate,  to provide  a  support  for  a  catalyst,  or  to  shield an object from electromagnetic radiation.

Abstract: ABSTRACT OF THE DISCLOSURE:           The present invention is concerned with an intermittent aeration type biological treatment process, wherein waste water is caused to flow into an tank, and an aeration step and a stop of aeration step are alternately repeated in the tank so as to treat the waste water and a system therefor.  Values of concentrations of dissolved oxygen during the aeration step of the waste water in the tank are continuously measured by a measuring device provided in the tank.  Deficient values of dissolved oxygen and dissolved oxygen variation values at predetermined time intervals are calculated from the values thus measured, the deficient values and variation values are integrated and processed by an calculating - integrating unit to calculate an oxygen requirement value for the activated sludge in the current aeration step, and a aeration time duration for the succeeding step is obtained from the value of this oxygen requirement value, to thereby control the operating time durations of the aeration device.  By use of the process and the system, wasteful operating energy can be eliminated and satisfactory treated water can be obtained constantly.

Title: Circuit for preventing lock-out of high priority requests to a system controller

Abstract: 52003004               28 August 1986               "PATENT"     ABSTRACT OF THE INVENTION       Lock-out of pending higher high priority requests to a system controller is prevented by a circuit which comprises a counter element for counting the number of times the pending higher high priority request is not granted access.  The counting results in a count value which is temporarily stored in the counter element.  A compare element compares the count value to a predetermined value, the predetermined value being a predetermined number of times the data processing system will permit bypassing the pending higher high priority request.  A control signal is outputted from the compare element when the count value is equal to the predetermined value and is coupled to each port to inhibit any further request for access from the equipment from being accepted by the system controller.  The circuit also includes a latch element for maintaining the control signal when it is determined that a subsequent high priority request which is granted access is not the highest high priority request, the control signal being maintained until all pending high priority requests have been granted access.

Abstract: ABSTRACT            The present invention relates to a method and apparatus for the  continuous  discharge  of  water  from  suspension, especially from fibrous pulp, whereby pulp is caused to thicken without having the water to be removed through a thick uncontrollably gathered fiber mat.   In accordance with the invention the suspension to be thickened is fed into a filtering chamber, the suspension equalizing the consistency differences, the liquid is continuously removed from the suspension and the thickness of the fiber mat being  formed  on  the  filter  surface  is  controlled  by subjecting said mat to shear stresses.  The above described method is realized by an apparatus, in which at lest one of the co-operating surfaces, the filtering surface (8) and its counter surface (10), is provided with means (12) for non-mechanically limiting the thickness of a fiber mat on the filtering surface, whereby a uncontrolled formation of a fiber mat on the filtering surface (8) is prevented.

Abstract: ABSTRACT A  method  for  producing  a  metallic  interface  suitable  for overlaying Consists of exposing the area of an alloy combination to be overlayed  to  a  temperature above  its  lower critical  until  an element reduced zone arises.   This element reduced zone more easily accepts  element  diffusion  that  takes  place  during  overlaying. Accordingly, an  improved interface,  one that is more ductile and less prone to cracking, is produced.
