Abstract: ABSTRACT OF THE DISCLOSURE    "FLUID FLOW CONTROL PROCESS AND APPARATUS"    The invention is concerned with controlling fluid delivery by a fluid dispensing system in which fluid is dispensed from a container, through a delivery tube, under the control of a flow controller or peristaltic pump and, particularly, with the control of the rate of fluid delivery to a patient by an intravenous infusion system utilizing a standard administration set.  The control apparatus continually monitors the weight loss of the fluid container, as fluid is dispensed, and produced data identifying the actual fluid delivery rate.  It compares this data with a signal identifying the selected delivery rate and provides for adjustment of the flow controller or pump so as to conform the actual delivery rate to the selected rate.  Because weight signals for computing the actual delivery rate are not immediately available upon initiation of a dispensing operation, the selected rate signal is initially processed by the apparatus to produce data for setting the flow controller or pump speed to a valve nominally corresponding to the selected delivery rate so that the the actual delivery rate is controlled as accurately as possible from the start of the dispensing operation.

Abstract: BLOOD TREATING AGENT                  ABSTRACT OF THE DISCLOSURE         The present invention provides (1) a blood-treating material containing a lipopolysaccharide derived from cell walls of Gram-negative bacteria and immobilized by an insoluble carrier containing an amino group and/or a carboxyl group, and (2) a process for producing the blood-treating material in which a condensing agent is reacted with a mixture of the lipopolysacchar-ide and the insoluble carrier.  Lipopolysaccharides have been known to exhibit antitumor effects against malignant tumors.          However, they have not been used safely, since their fatal doses are very close to the minimum effective doses in the treatment of such tumors.  The present invention makes it possible to reduce the lethal toxicity of the abovementioned lipopolysacchar-ides and provide a therapy for cancer, because the unique blood-treating material disclosed herein not only has antitumor effects similar to those of the lipopolysaccharides derived from the cell walls of Gram-negative bacteria but no fatal effects are observed at antitumor effective dosage levels.

Abstract: ABSTRACT OF THE DISCLOSURE:         A device for the uptake, transportation and recovery of cell material present in body fluids, cell-fixing liquids, and mixtures of body fluids and cell-fixing liquids, and also for the transfer of the recovered cell materials to microscope slides.  The device comprises a vessel with an inlet and an outlet;  a removable fiber element is arranged, flush with the wall, in the outlet, and comprises fibers which are insoluble in body fluids and cell-fixing liquids and which are arranged lengthwise in the direction of the long axis of the vessel with the formation of through capillaries, such that the capillaries have a smaller diameter than the diameter of the cells.          The vessel can be liquid-tightly and gas-tightly closed.    Preferably, the fibers of the fiber element are crimped and/or texturized fibers and/or hollow fibers.  In contrast to conventional devices and methods for the recovery of cells from cell-fixing liquids, in which the cells must be caused to sediment or settle and a long time is required, the separation of cells and cell-fixing liquids takes place in a very short time with the device according to this invention. Apart from this, the recovered cells can be directly transferred to microscope slides.

Abstract: ABSTRACT OF To DISCLOSURE     An aquatic surface projectile for recreation and/or exercise use either individually or in team play.  The aquatic device is manually propelled by throwing so as to skim along the surface of a body of water in a smooth skimming action and not by skipping or tumbling.  The lower surface of the projectile is preferably an inverted frusto-conical shape, with shape variables including the inner radius, the outer radius, and the altitude angle. The lower surface shape produces a positive, nose-up attitude and hydrodynamics lift to reduce drag for enhancing range and velocity of the projectile while providing smooth skimming on the water surface.  In addition to the projectile shape considerations, the projectile is also made relatively lightweight to provide enhanced skimming action and to prevent undesired skipping and tumbling of the projectile.

Abstract: Abstract There is disclosed a domestic satellite communication system, including a demand assignment central earth station which controls the frequency assign-ment of voice communication satellite channels in correspondence to the occur-rence of calls, which discriminates a subscriber earth station-to-subscriber earth station call and which is connected to a central switching system for carrying out a voice switching operation, and a plurality of subscriber earth stations each of which accommodates at least one voice communication terminal. Each of the subscriber earth stations comprises:  indication means for indicating that a call discriminated at the central earth station is the one for a sub-scriber earth station-to-subscriber earth station; means for monitoring a communication continuity state at the voice communication terminals; and means for periodically transmitting an out-of-band signal to a voice communication satellite channel which is assigned by the central earth station while the monitoring means detects the communication continuity state and the indication means indicates the subscriber earth station-to-subscriber earth station call. The central earth station comprises:  means for demodulating the out-of-band signal transmitted from the subscriber earth station; means for receiving the out-of-band signal which has been demodulated by the demodulating means; means for monitoring the communication continuity state between the subscriber earth stations by periodically reading out the output of the receiving means; and means for making a tuned frequency of the demodulating means coincide with a frequency assigned to the voice communication between the subscriber earth stations.  The subscriber earth station-to-subscriber earth station call is thus connected through one satellite link.

Abstract: ABSTRACT OF THE DISCLOSURE     A pressure-reduction device  forms  part  of   a quick coupling  in  the  first  and/or second part of said coupling. The part of the coupling concered thus comprises a first valve member equipped with a valve body being ei-ther fixed or capable of linear displacement by means of which a first passageway for the fluid is able to be opened and closed. The device includes a second valve member ar-ranged  in  said valve body comprising a ball capable of being caused to bear against a seat by means of a spring member arranged in a recess in the valve body. Said ball is raised against  the effect of said spring member when the first and second parts of the coupling are connected together.  In so doing the ball opens a second passageway for said  fluid before actuation of  the first passageway takes place,  thereby creating a pressure-reduction effect in the part of the coupling concerned  thanks to a small quantity of the fluid being diverted from the inside of the part of the coupling via the second passageway. The spring member acts upon the spherical member via a power transmission member.  The latter is guided by the wall of the   recess   and/or   by the inside   and/or  outside of the  spring member.  The  power  transmission member  is  so arranged as to permit the flow of fluid to pass into the recess during the aforementioned process of being diverted.

Abstract: FRACTIONALLY SPACED EQUALIZATION USING  NYQUIST-RATE COEFFICIENT UPDATING     Abstract A fractionally spaced adaptive equalizer is disclosed wherein the coefficients are updated synchronously by an integral -T error circuit and alternately by a fractional -T error circuit.  This arrangement features a single unique minimum for the adaptive structure thereby preventing the coefficient drift to very large values so coefficient tap leakage is not required to minimize coefficient values.  The adaptive characteristic is well suited for linearly dispersive channels, such as exhibited during terrestrial radio transmission during tropospheric multipath propagation.          The inventive principles are broadly applicable to any of the well known algorithms for adapting digital filters.  A configuration of fractionally spaced equalizers provides the benefits of Nyquist-rate coefficient updating for a dual rail quadrature amplitude modulated signal application.
