Abstract: CONTROLLER FOR A DUAL DRUG DELIVERY SYSTEM                 ABSTRACT OF THE DISCLOSURE         A system for controlling the flow of intravenous fluids to a patient provides for the sequential administration of two different intravenous fluids at independently preselected drop rates.  The system includes a primary administration set associ-ated with a first fluid container, a secondary administration set associated with a second fluid container, and a controller having a control valve operatively associated with both adminis-tration sets to control the fluid flow rare through the particular administration set in use.  The system further comprises a con-nector means in the primary administration set, upstream from the control valves for joining the secondary administration set to the primary administration set.  A one-way valve, disposed in the primary administration set upstream from the connector means, prevents fluid flow through the one-way valve whenever hydro-static pressure in the secondary set is greater than the hydro-static pressure in the primary set. Drop sensors, operatively associated with drip chambers in each of the administration sets, are electrically connected with the controller to monitor and sense whether there is fluid flow in the particular system.  The controller also includes a pinching device which is activated to pinch IV tubing in the secondary set when the controller either senses no flow rate through the secondary set or senses a suffi-cient flow rate in the primary set.  This pinching action causes an instantaneous reversal of the hydrostatic pressure differential at the one-way valve and permits immediate fluid flow from the first fluid container at a controlled rate through the primary administration set to the patient.

Abstract: PHOTODETECTOR WITH ISOLATED AVALANCHE REGION                ABSTRACT OF THE DISCLOSURE         The invention relates to an avalanche photo-detector having a charge-multiplication region which is spatially separated from the detector surfaces.  This photodetector includes an absorptive region, a first region overlying the absorptive region and having a higher concentration zone and a surrounding peripheral zone and a second region overlying the first region.  The high electric field in the avalanche region is then restricted to the higher conductivity central zone thereby reducing the electric field at the detector surfaces when a reverse-bias voltage sufficient to produce avalanche multiplication is applied to the detector.

Abstract: ABSTRACT OF THE DISCLOSURE A multi-channel electronic waveform recorder for storing sampled waveform data and time of occurrence, information, i.e. a "time-tag", for each stored sample, is disclosed. Specifically, each channel of the waveform recorder converts a previously stored digital sample of a recorded waveform into an analog value, compares this value to the current value of the input signal, generates an analog difference signal in response to this comparison, and stores a digital sample substantially equivalent to the current value of the input signal whenever the magnitude of the difference signal exceeds a predetermined amount.

Abstract: BEARING RING OR THE LIKE WITH SET SCREW              ABSTRACT OF THE DISCLOSURE      The invention contemplates an improved set-screw shaft mounting for a machine element such as the inner race ring of an antifriction bearing.  Tolerances are closely controlled for both the set-screw threads and the tapped-hole threads, for the case of set-screw threads which are yieldable in the context of an interference (i.e., friction-fit) to the tapped hole, the interference being such as to occasion a friction torque which is but a small fraction of the conven-tional maximum comfortable torque of wrench appli-cation by a machinist, using a conventional wrench, such as an Allen wrench.  The low friction torque enables the machinist to know precisely when the set screw intercepts the shaft into which it is driven, and he can then know that his manually applied maximum torque will be serving essentially only the intended purpose of clamping to the shaft.          Extended running life is realized for bearings thus mounted, as compared to conventional set-screw clamping.

Abstract: IMPROVED EPOXIDATION PROCESS PROVIDING LOW OLEFIN OLIGOMER BY-PRODUCT FORMATION                        (D#80,314-F) ABSTRACT OF THE DISCLOSURE         A method of preparing an epoxide compound by re-acting an olefinically unsaturated compound with an organic hydroperoxide in the presence of a molybdenum catalyst is described.  The amount of alkylene oligomer by-products in the crude reactor effluent is routinely 10 ppm or less.  In the case where propylene oxide is made, this translates to about 40 ppm or less on a "pure propylene oxide" basis.  The very small amount of alkylene oligomer by-product can be left in the alkylene oxide product thus avoiding a costly dis-tillation step.  The reaction should be conducted at a temp-erature between about 90 and 140°C, preferably 100 to 130°C.          Preferably, the mole ratio of olefinically unsaturated com-pound to organic hydroperoxide is 0.9:1 to 3.0:1.  It was surprisingly discovered that the method of this invention works much better with t-butyl hydroperoxide as the organic hydroperoxide than with other hydroperoxides such as cumene hydroperoxide.

Abstract: PRODUCTION OF EPOXY PHOSPHATES                       ABSTRACT        A process of producing a water dispersible epoxy phosphate-solvent mixture is disclosed which comprises heating the solvent with orthophosphoric acid to reaction temperature together with additional water so that the total amount of water is sufficient to hydrolyze at least about 50% of the oxirane functionality in the polyepoxide which is used, slowly adding a resinous polyepoxide to this heated mixture so that reaction with phosphoric acid and hydrolysis of the oxirane groups will occur simultaneously to minimize the concentration of oxirane functionality in the reaction mixture as the reaction proceeds, thus minimizing epoxy-epoxy reactions which tend to increase the molecular weight of the epoxy phosphate which is formed, and then adding volatile amine to destroy any remaining oxirane functionality and to neutralize the epoxy phosphate to provide a water dispersible epoxy phosphate-solvent mixture.
