Abstract: 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 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, particu-larly at vary high flow rates, where the fill stroke period is of signifi-cantly large duration relative to the pump stroke 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 rela-tionship between the preselected 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.

Abstract: ABSTRACT OF THE DISCLOSURE     A cap for a molded plastic container has a cover section and a seating section which are provided with a tear strip for obtaining drinking or pouring access to the contents of the container without removal of the cap. The cover section has a centrally raised portion and a portion which slopes downwardly and radially outward from the centrally raised portion and terminates in a circumferentially extending seating portion. The latter includes an outer, downwardly extending skirt which embraces the upper end of the container, Two parallel slots extend part way up from the edge of the skirt and terminate in a groove which extends to the edge of the cover section and then follows the surface of the cover section in a generally radial direction to form a tear strip having a continuous, wedge-shaped configuration. The two parallel slots form a tab for grasping the tear strip with the fingers. Because of the shape of the cover section, a twisting motion of the wrist easily tears away the wedge-shaped section along the lines of the groove to provide access to the contents of the container without the need for removing the cap. A fulcrum to enhance tearing action is established by a raised circumferential ridge of the cap against which the container is seated and another fulcrum is established at the juncture of a wall portion of the cap seating section with the sloping portion of the cover section.

Abstract: ABSTRACT An accumulator structure for use in a hydraulic control system for controlling an hydraulic motor utilized to engage a friction device in a transmission including an accumulator piston mounted in a housing, a source of fluid pressure, a valve connected between the source and the motor.  A first conduit connects the valve and motor, the first conduit including a fluid restriction, and a second conduit connects the valve and the accumulator.  A third conduit is provided between the accumulator and the first conduit.  The accumulator includes a counter-bored portion defining together with a reduced land portion on said piston, a passage which connects the second conduit to the third conduit when the piston is in the inactive position to provide a rapid fluid fill of the motor initially.  The land on the piston blocks the connection between the second and third conduits when the piston is moving between the inactive and fully "stroked" positions, and a flow path is provided in the accumulator to connect the second conduit to the third conduit again when the piston reaches its fully "stroked" position whereby in case of a leak of pressure at the servomotor, the connection between the second and third conduits will provide sufficient fluid flow to prevent a pressure drop at the hydraulic motor caused by the restriction in the first conduit under the leak condition such that sufficient engaging force is maintained to prevent slipping of the friction device.

Abstract: ABSTRACT OF THE DISCLOSURE           A facsimile reproduction system is disclosed.  The system utilizes a laser beam at the transmission station to scan across an image to be reproduced through an acousto-optic modulator (AOM) cell.  The laser beam is reflected off the image onto photo detector cells to generate electrical signals analagous to tonal variation in the image.  A laser beam at the receiver station is also provided to sensitize a sheet of sensitized paper to produce a facsimile of the image.  The intensity of the receiving station laser beam is modulated in accordance with the photo detector electrical signals by applying the signals to an rf carrier which then is applied to an AOM cell positioned between the laser and sensitized paper.  Both the transmission and reception laser beams are rapidly deflected by modulating the frequency of the rf carrier driving the respective AOM cells so that the intensity of the effective scanning profile (perpendicular to the direction of scan) is constant across the entire width of the scan line for both transmission and reception and is close to the ideal profile.
