Abstract: FLUID RELAY APPARATUS        Abstract A control valve includes a single diaphragm as a common wall between an input signal chamber having an input port and an output chamber having a central supply port and an exhaust orifice.  The orifice has a seating face parallel to and spaced from the diaphragm.  A spring-loaded ball valve unit in the supply passage is aligned with an operator moving with the diaphragm.  An increasing input signal first moves the diaphragm to close the exhaust orifice and thereafter moves the operator to open the supply valve.  Pressure builds in the output chamber, tending to return the diaphragm and close the supply valve until the output and pilot pressure are balanced.  The supply valve then closes. As the exhaust is sealed off, this effectively seals the output chamber.  If the signal decreases, the diaphragm uncovers the exhaust orifice until a new balanced state is created.  In high flow capacity systems a multiplicity of exhaust orifices are employed to match exhaust and supply flow capacity while maintaining minimal leakage.

Abstract: ABSTRACT OF THE DISCLOSURE      This invention relates to improvements in fluid flow control systems for partneral administration of medical fluids. Prior art control systems are generally adaptable for only a single type of output device and are often deficient in their regulating accurately over a wide range of flow rates.  The present invention overcomes these deficiencies by providing an apparatus and method for improved accuracy of parenteral administration of medical fluids.  The inven-tion includes producing a pulse train of variable frequency and pulse width from a digital pulse generation and control system, the frequency and pulse width of the pulses in the pulse train being selected and controlled by the system to establish drop flow rates with digital precision over an extremely wide dynamic range.  The invention pro-vides for  monitoring the pulse train driving an output control device used in administration of the fluids, in order to detect a abnormal operation of he administration system.  The monitoring involves searching for a first pulse width in a prescribed sequence and searching for a second pulse width in the prescribed sequence dif-ferent from the first pulse width to provide an alarm indication. Duty cycle limitation, appropriate to the particular operating characteristics of the electromechanical output device utilized, is implemented to avoid inducing run-away free flow conditions. Addi-tionally, appropriate alarms respond to system malfunctions to alert medical personnel.

Abstract: Abstract of the Disclosure An improved process is provided for making a precipi-tated cellulose product wherein cellulose is dissolved in a sol-vent containing both a tertiary amine N-oxide solvent and water and precipitated therefrom with water or other non-solvent fox cellulose.  The water content of the solution may be adjusted to any level of up to about 29% by weight, preferably between 1.4% and 29% by weight.  Also, in practicing the invention, the amount of water included in the solvent is decreased substantially linearly as the amount of cellulose to be di solved increases.          A solution substantially free from undissolved cellulose and solid tertiary amine N-oxide which is adapted to be spun, ex-truded or molded at a temperature below the melting point of the tertiary amine N-oxide can be prepared with a tertiary amine N-oxide solvent which contains water as contemplated by the inven-tion.  Preferably, N,N,N-triethylamine N-oxide or a tertiary amine N-oxide having a cyclic or pseudo-cyclic molecular struc-ture is mixed with water to form the solvent for cellulose.

Abstract: DIGITAL PHASE DETECTOR AND METHOD     ABSTRACT OF THE DISCLOSURE     A digital phase detector includes a hard limiter which transforms an incoming signal of known-frequency into a binary signal at the same frequency.  A reference generator produces two binary references at the signal frequency, one reference shifted 90° in phase with respect to the other. The binary signal is exclusive-ORed with each reference and the exclusive-OR outputs therefrom control two counters, the counters thereby registering counts analogous to trigono-metric functions of the signal phase angle. A phase modulated clock drives the counters, the phase modulation feature per-mitting a correction factor to be incorporated in order to cancel the error introduced by the quantized nature of the digital computations involved.

The lower rigid section has a casing extending from a preset base on the marine bottom to a point just below the zone of turbulence which exists near the surface of the water.  A variable-buoyant buoy having a curved upper surface and a central passage there-through is mounted on the upper end of the casing to support the casing in a substantially vertical position when the casing is in position on the preset base.  A remotely actuated connector assembly is provided on the lower end of the casing for connecting the casing to the preset base.  A plurality of conduits are run through the passage in the buoy and through guide means in the casing and are remotely connected to mating conduits on the base.
