Abstract: Prema pronalasku je namenjena za transport čvrstih, tečnih i gasovitih materijala posredstvom nekog fluida (voda, vazduh). Pumpa se sastoji od dovodnog cevovoda (1), unutrašnjeg mlaznika (2), cevovoda (3) za dovod čistog fluida, unutrašnje komore (4) za mešanje, kanala (5) za napajanje svežim materijalom, spoljnjeg mlaznika (6), spoljašnje komore (7) za mešanje komore (8), difuzora (9) i transportnog cevovoda (10). Čist fluid ulazi u unutrašnji mlaznik (2) iz. cevovoda (3) za napajanje čistim fluidom i iz mlaznika ističe velikom brzinom. Mlaz zahvata materijal koji ulazi u unutrašnju komoru (4) za mešanje kroz kanal (5), mesa se sa njim i predaje mu energiju i mešavina velikom brzinom isuče iz spoljašnjeg mlaznika (6) u spoljašnju komoru (7) za mešanje gde se meša sa mešavinom koja cevovodom (1) dolazi do spoljašnje komore (7) za mešanje. Tu se predaje energija mešavini i nakon prolaska elementa (8) i smirivanja u difuzoru (9), mešavina se transportuje cevovodom (10) ka potrošaču ili drugoj mlaznoj pumpi.Otvaranje - zatvaranje unutrašnjeg mlaznika (2) i kanala za napajanje materijalom koji se transportuje ostvaruje se varačem (11), koji je oslonjen na ležajeve (12) koji su od prevelikog habanja zaštićeni čaurama (13) sa raspršivačima.

Abstract: A process for continuous conveying of a fine-grained and/or pulverized solid to two or more target points by a conveying medium, e.g. gas. The solid is charged into a distribution vessel and from there to several target points by respective supply lines each at a desired target flow rate intended for target point. The target flow rate for each target point is divided into at least two partial target flow rates from the distribution vessel via separate partial supply lines. The partial target flow rates are reunited at the respective target points at the latest. To adjust the target flow rate at a target point at a specific level, individual partial supply lines leading to this target point are alternatively kept shut-off or open.

Abstract: ABSTRACT OF THE DISCLOSURE         Perfluorocyclocarbons and emulsions containing emulsified particles of these perfluorocarbons are useful in supporting life as intravascular oxygen and carbon dioxide transport agents.  Stable emulsions of perfluorocarbocyclic derivatives are prepared for use as artificial bloods and perfusates for organs.  Intravenously infused emulsions containing perfluorocyclocarbons such as perfluoro(methylcyclo-hexane), perfluoro(1,3-dimethylcyclohexane), perfluoro(deca-hydronaphthalene), perfluoro(decahydro-1-methylnaphthalene), perfluoro(decahydrodimethylnaphthalene), and the like, serve as intravascular oxygen and carbon dioxide transport agents.          Fluorocarbon liquids are also useful as an external respira-tion media for transporting oxygen-carbon dioxide necessary to support intravascular respiration.  Perfluorocyclocarbons have been found after intravenous emulsion infusion as artificial bloods to collect in the reticuloendothelial system (RES) of the animal body.  However, it has also been found that perfluorocyclocarbon compounds leave the RES of the animal body and certain of these compounds, e.g., perfluoro(decahydronaphthalene), leave the RES at a much faster rate than others.  Furthermore, after the intravenously infused perfluorocyclocarbon emulsions function as artifi-cial bloods, the perfluorocyclocarbons have the capability of leaving the animal body through the tissue, e.g., the lungs and skin.  The invention described herein was made in the course of work under a grant from the Department of Health, Education and Welfare.

Abstract: ABSTRACT OF THE DISCLOSURE         System for transport of sheet material, particularly flexible sheets such as paper or the like.  A continuous belt either of flexible, porous material or solid spaced apart belts is supported at each end by a roller one of which is driven. The conveyor belt extends unsupported between the two rollers.  The rollers and continuous belt are enclosed to the extent possible.  The bottom of the enclosure is provided with a fan for drawing a mass volume flow of air through and around the belt or belts.  The enclosure is not sealed to any of the parts but insures that the major portion of the air volume drawn by the fan passes through the belt system and out through the fan.  This transport system relies on a column of air moving through or around the belt or belts to hold the sheet material positively thereon as it moves.

Abstract: HIGH STABILITY MODULATOR FOR  INSTRUMENT LANDING SYSTEMS ABSTRACT OF THE DISCLOSURE In an instrument landing system for aircraft, the transmitter is required to produce an amplitude modulated signal comprising a carrier wave having side-bands containing the sum of a 90 Hz and a 150 Hz signal as modulation, and to also produce a double sideband, suppressed carrier signal in which the modulation is the difference between the 90 Hz and 150 Hz signals. In the present invention, the 90 Hz and 150 Hz signals are summed to provide a composite modulating signal that is employed to directly modulate the radio fre-quency carrier.  To provide the double sideband signal the carrier is fed to a 180° phase shift network, and the carrier and the network output are alternately delivered to a modulated amplifier stage by an RF switch which is operated with each change in the sign of a dif-ference signal derived from the 90 Hz and 150 Hz signals. Accordingly, the output from the RF switch is a phase-changing carrier that undergoes a phase reversal with each change in the polarity of the difference signal. This phase-changing carrier is modulated with a modulating signal that is the absolute value of the difference sig-nal, and the resultant is the desired double sideband, suppressed carrier output.  A high gain operational ampli-fier in conjunction with an envelope detector in a negative feedback loop is employed with both the AM and the DSB modulators to insure high stability.

Abstract: ABSTRACT OF THE DISCLOSURE          Apparatus and method are provided for concurrently decreasing the cyanide and heavy metal content of an aqueous solution, such as a waste water.          The apparatus comprises an electrochemical cell provided with separate cathode and anode compartments.  Each of the compartments contains a bed of electrically con-ductive particles.  The compartments are separated by an electronically nonconductive foraminous member.          In accordance with the method, an aqueous solution containing cyanide ion and at least one heavy metal in soluble form is passed sequentially through the beds of electrically conductive particles contained in each of two compartments of an electrochemical cell.  A direct electric current is passed between the two compartments making one compartment cathodic and the other anodic.  The heavy metal is deposited upon the particles in the cathodic compartment and the cyanide is oxidized in the anodic compartment.  The aqueous solution having a substantially reduced cyanide and heavy metal content then is discharged from the electrochem-ical cell.

Abstract: ABSTRACT OF THE DISCLOSURE               Apparatus is disclosed for sensing and transmitting the stimulating pulse of an implanted pacemaker over readily available, low-bandwidth transmission media to a remote receiver capable of measuring the pulse width to provide an indication of the condition of the pacemaker energy source, e.g. a battery.  In  particular, the sensing and transmitting apparatus detects the electrical activity, e.g. the EKG, of a patient through attached electrodes and modulates a carrier or tone of a suitable frequency to be transmitted over the low-bandwidth transmission medium to the receiver, along with a pulse signal multiplied by a selected, fixed factor dependent upon the carrier frequency of the signal and the other information to be transmitted to the receiver.  Illus-tratively, a factor in the range of 30-50 is selected where it is desired to transmit the pulse width of the pacemaker stimu-lating pulse along with an EKG, to a receiver to be displayed in a manner to permit evaluation of the EKG and of the width of the stimulating pulse.  Typically, the patient in which the pacemaker is implanted has a transmitter for transmitting the aforementioned data to a receiver located in the doctor's office clinic or hospital, whereby a regular check of the pacemaker's energy source may be made by the patient's doctor.
