Abstract: ABSTRACT OF THE DISCLOSURE         This method of making 5,6-dihydro-2-methyl-N-phenyl-1,4-oxathiin-3-carboxamide is based on the use of an oxathiolane, namely, 2-methyl-N-phenyl-1,3-oxathiolane-2-acetamide, which may be formed by condensing 2-mercap-toethanol with acetoacetanilide under acidic conditions in a solvent medium (aromatic hydrocarbon, chlorinated hydrocarbon or alkyl ester of an aliphatic acid).  The said oxathiolane, with or without purification, is reacted with hydrogen peroxide in water or in a water-organic solvent mixture under basic conditions in the presence of a catalytic amount of a metal compound such as sodium tungstate to form 2-methyl-N-phenyl-1,3-oxathiolane-2-acetamide 3-oxide.  The said oxathiolane oxide, while dissolved in a chlorinated hydrocarbon or an alkyl ester of an aliphatic carboxylic acid, or while suspended in an aromatic hydrocarbon, is subjected to a ring expansion reaction by heating under acidic conditions in the presence of a catalytic quantity of a quaternary ammonium salt to form 5,6-dihydro-2-methyl-N-phenyl-1,4-oxathiin-3-carboxa-mide with evolution of water.  The product is a known bactericide and fungicide.

Abstract: ABSTRACT OF THE DISCLOSURE           This invention relates generally to improvements in fluid flow control systems for parenteral administration of medical liquids. Positive pressure infusion pumps of the syringe type are known. However, since a portion of each of operating cycle with such syringe type pumps is concerned with filling the syringe, rather than delivering fluid to the patient in a pumping mode, the accuracy of such devices tends to fall off, particularly at very high flow rates, where the fill stroke period is of significantly large duration relative to the pump str? ? period.          The present invention overcomes this deficiency by providing a system for fluid flow control utilizing a syringe pump operated by a stepping motor to repetitively fill and empty a syringe cartridge over a plurality of operational cycles of successive fill stroke and pump stroke periods.  The stepping motor is driven by electrical drive pulses from a digital pulse generation and control system.  Means are provided for maintaining a proportional relationship between the pre-selected pumping rate and the actual fluid flow pumping rate over each complete cycle of successive fill and pump strokes, the motor drive pulse frequency  during each pump stroke is automatically increased to compensate for the time lost during each fill stroke. A detection device is provided which responds to the lack of motor rotation within a defined period.

Abstract: ABSTRACT OF THE DISCLOSURE      A data acquisition system utilizing a microcomputer and incorporating a plurality of monitors each adapted to produce an electrical signal indicative of a physical con-dition of apparatus to be monitored.  The electrical signals are fed via multiplexing equipment and analog-to-digital converters into the microcomputer which is equipped with print-out means.  The system is such that the level of any one or all of the signals from the respective monitors can be printed out as well as a change in the condition of any signal.  Means are incorporated into the computer for calculating and printing the trend (i.e., the slope of a plot of signal amplitude versus time) of a succession of stored signals from any monitor which would indicate a probable malfunction of a device being monitored and the probable time to failure.  In the case where the signals from the monitors comprise vibration signals, the system performs an automatic frequency spectrum analysis whenever a probable or actual malfunction is detected.

Abstract: PARISON HANDLING ASSEMBLIES & METHODS FOR HANDLING PARISONS                    ABSTRACT OF THE DISCLOSURE 164.085-164.088 A parison handling assembly receives tubular plastic parisons from a random bulk storage, orients the parisons, and feeds the parisons in a controlled manner to one or more blow molding machines. Parisons are stored in the random bulk storage and fed at a controlled rate by a metering apparatus to a parison orienter which orients the parisons into a closely grouped arrangement wherein the parisons are both upright and side-by-side. The parisons are fed from the parison orienter to a parison escapement mechanism which holds the parisons temporarily. The escapement mechanism is actuated to release parisons into a parison transporter depending on the production demands of the individual blow-molding machines. Released parisons, from the parison escapement mechanism, move along the parison transporter to be pushed axially into stuffer tubes. The stuffer tubes hold the parisons in properly oriented, end-to-end relationship for delivery to the actual loading station of the blow-molding machine.

Abstract: ARTICULATION FOR LEGS OF DOLLS           ABSTRACT OF THE DISCLOSURE             The disclosure relates to an articulation for legs of dolls, especially those with hollow bodies, made up of two halves which are bonded together permanently.  The lower end of the body is closed by a horizontal plane and defines an opening in said plane into which the upper ends of two equal legs are tightly fitted.  A cylinder-like axle is provided at the front edge of the opening, while the sides and rear edges of the opening follow the contour of the legs.  The upper end of each leg is bent forward and has an internal radius equal to the axle in the opening, so the legs are hooked on the axle thus being able to turn forward and downward, while the external curvature of the upper ends of the legs is also concentric to the above-mentioned axle, so they move against curved guides located on the inside of the doll's body.  These guides also serve as support for the legs and prevent them from being incorrectly inserted in the doll's body.

Abstract: ABSTRACT OF THE DISCLOSURE A current limiting circuit interrupter includes two parallel pivoting contact arms carrying contacts at the ends thereof.  The upper contact arm is pivoted upon a carriage which is in turn pivotally mounted upon a mechanism frame.  A latch rod is movably secured in arcuate slots in the sides of the mechanism frame.  When the circuit in terrupter is in the closed circuit position, a pair of springs connected between the latch rod and the carriage urges the latch rod against a reaction surface of the upper contact arm to provide contact closing pressure.  Upon occurrence of severe overload current conditions, the upper contact arm pivots upon the carriage, moving the latch rod within the arcuate slots to release the contact closing pressure, allowing the springs to move the latch rod against a latching surface of the upper contact arm to latch the upper contact arm in the open circuit position.
