Abstract: ABSTRACT OF THE DISCLOSURE    A novel bileaflet mitral heart valve is provided herein, which. in two alternative embodiments, may have symmetrical leaflets or asymmetrical leaflets.  The valve has a stent including a circular base and a pair of upstanding struts separating a pair of arcuately-shaped, depressed, reliefs, each such relief being bounded by a smooth curve interconnecting the struts to the circular base.  A flexible, durable, bicompatible covering. e.g. a pericardial covering, is secured to the stents and provides two opposed moulded, flexible. flappably-movable valve leaflets secured along the smooth curve defining the upper perimeter of the reliefs.  These valve leaflets each are preformed and moulded so that the free margin of the biocompatible leaflets along the free edge of each of the leaflets between the tips of the struts is related to the circumference of the circular base such that, when the valve is in the open position, the cross-sectional area is substantially equal to the inside cross-sectional area of the circular base, and when the valve is in its relaxed and natural closed position, the free edges of the leaflets drop down and sealingly meet in substantially wrinkle-free form at a curve of apposition, preferably in the plane defined by the tip of the struts and the axis of the valve. to provide symmetrical leaflets, and, in one embodiment. may follow the approximate shape of a catenary curve.          The shape of the leaflets in that closed position approximates Abstract of the Disclosure (continued) that of a surface formed by two coapting bubbles under pressure.          That shape is defined by five simultaneous equations as disclosed herein.  The two leaflets may thus approach the configuration of the natural human mitral valve.

Abstract: ABSTRACT OF THE DISCLOSURE         A macro phase detector responds to large phase deviation between a locally generated signal and a reference signal for actuating a successive frequency approximation register to effect major count alteration in a counter for controlling a digital-to-analog converter and, in turn, a voltage controlled oscillator.          Small phase error is detected by a phase detector, averaged, and employed to alter the count in the counter for introducing sensi-tive frequency adjustment.  A second counter is clocked by the phase detector at one half the rate of the first counter and is used to update the first counter each time the phase difference reverses polarity.  Loss of reference signal activates a detector for freezing the count in the counter to maintain frequency and phase within the accuracy of the controlled oscillator.

Abstract: ABSTRACT OF THE DISCLOSURE        A liquid pump is provided and particularly a downhole pump for use in an oil well bore for pumping oil or in a gas well to re-move condensate.  The downhole pump includes a plurality of pump and transfer modules, each of which includes an elongate housing with end couplings and with two internal passages extending there-through.  The pump module further has a bladder extending between the end couplings around the internal passages with the couplings having passages connecting one of the internal passages to space on one side of the bladder.  When fluid, preferably gas, under pressure is supplied to that passage, the bladder forces liquid therein upwardly into the next module.  At the same time, fluid under pressure is exhausted through one of the passages from the space on the opposite side of the bladder of the next pump module, aiding it to receive liquid from the pump module therebelow.  The transfer modules supply the liquid up from a lower pump module to an upper one and connect the fluid passages to enable the fluid to operate the bladders.  The modules have check valves at the lower ends enabling flow of liquid only in the upward direction. However, the check valves have provisions for being opened when fluid under greater than operating pressure is applied thereto to enable liquid in the modules to drain back down through the pump.

Abstract: ABSTRACT OF THE INVENTION A trip signal generator comprises a circuit possessing an inverse time-current characteristic for producing a trip signal in response to the occurrence of overcurrent in an alternating current line. The trip signal is produced after the passage of some time period, which varies inversely with the difference between the absolute magnitude of the overcurrent and a threshold current. The circuit includes a portion which produces pulses at a rate proportional to the difference between the absolute magnitude of the overcurrent in the line and the threshold current. The circuit produces no pulses when the line current is less than or equal to the threshold current. The circuit includes a counter for counting the pulses and for producing the trip signal after the counting of a selected number of pulses. Another portion of the circuit enables the counter when overcurrent is in the line, but resets the counter and prevents its operation when the line current is less than or equal to the threshold current. The counter may include a plurality of selectable outputs, each corresponding to a different count, thereby permitting the length of the delay before the trip signal is generated to be varied by selecting a different one of the outputs. The circuit also may include one or more range selectors for automatically selecting among two or more counter outputs so as to produce the trip signal after the passage of different ranges of time period corresponding to different ranges of overcurrent.

Abstract: IMMUNOASSAY METHODS EMPLOYING PATTERNS FOR THE DETECTION OF SOLUBLE AND CELL SURFACE ANTIGENS          Abstract Methods for determining the presence of antigens or antibodies in an aqueous sample or presence of antigens on the surface of cells.  A preferred embodiment employs fluorescent antigens which compete with the sample antigens for antibody binding sites.  The antibodies are deposited on a support surface means in alternating patterns.  The surface means and fluorescence detector are translocated with respect to each other and a signal generated by the detection of the repeating pattern of fluorescence.  The signal is analyzed by means of a gated integrator responsive to a gate track control means also located on the surface means.  Immunoassay methods having increased sensitivity are thereby obtained.

The container has a heating system for raising a thermal medium to a temperature above the melting point of the plastic residue.  The container can be tilted about a horizontal axis between a horizontal charging position and an upright operating position.  A tank for the thermal medium is arranged to be beneath the container when in the charging position, and is connected to the container such that, when the container is tilted into the operating position, the thermal medium flows into the container and when the container is returned to the charging position the medium flows back into the tank. An overflow establishes the maximum charge level of the thermal medium within the container.  The apparatus can be used primarily for the convenient, energy and time efficient cleaning of extruder screws.

Abstract: ABSTRACT The disclosure describes a method of bonding a sole to a shoe upper by  providing on attaching surfaces of one or both of the sole and shoe upper a layer of adhesive composition comprising a moisture curable poly-urethane formed from a first component comprising a di-isocyanate, and a second component comprising a substan-tially linear hydroxy polyester in proportions to provide a prepolymer having NCO groups available for reaction, and a third component comprising a monofunctional reactant present in an amount sufficient to react with up to 40 mole % of the NCO groups of the product of the prepolymer reaction.  Each layer of adhesive composition is then exposed to airborne moisture to bring about chain exten-sion of the urethane moisture curable polyurethane.  The layer or at least one of the layers of the adhesive composition is heated to bring it to tacky adhesive condition, and the attaching surfaces of the sole and upper are pressed together with the composition between them to form an adhesive bond between the sole and the shoe upper.  The composition used in this method is also disclosed.  This method results in sole attaching in a convenient manner without exposing the shoe upper or sole to excessive conditions of temperature and humidity.
