Abstract: A B S T R A CT An infusion system for administering multiple infusates at individually programmable rates, volumes, and sequences in any order from any one or more of plural fluid input ports through a patient output port and into the circulatory system of a patient. Infusates may be either continuously or time sequentially administered, and infusates may be either intermittently administered at selectively regular intervals or in time overlap to administer a dilution. Various error conditions are automatically detected and alarms generated in the event ofconflicts between infusates, to identify times of no infusions, and to identify system malfunctions. The system is selectively operable, among others, in a priming mode, a maintenance mode, a normal-on mode, and a manual override mode. The system is operative to adapt actual to desired flow rates in normal operation. All fluids now through a unitary disposable cassette without making any other system contact. Air bubbles in the fluid line are automatically detected and disposed of. Fluid pressures are monitored and system operation adjusted as a function of such pressures. Infusates may be administered from syringes as well as from standard bag or bottle containers. Infusate from a selected input port may be controllably pumped into a syringe for unsticking the syringe plunger, The system is selectively operable to adjust total fluid volume and rate to below preselected values for patients whose total fluid intake must be restricted. The system is operable to maintain an accurate record of total infusion history.

Abstract: ABSTRACT OF THE DISCLOSURE           A novel device to be used in performing chest exercises is disclosed.  It comprises two interconnected levers to which standard weight plates may be attached.  A torsional spring provides resistance to the bringing together of the free ends of the levers.  To use the device, a person, after affixing suitable weight plates to the device, lies on his back and grips the levers near their free ends.  He then pushes the device upwardly in a bench-press type motion, and forces his hands together against the resistance of the spring.  The novel U-shaped frame is of use in other standard exercises such as squatting movement, calf raises, bent over bows, and shrugs.

Abstract: ABSTRACT:     An opto-matrix touch input device which samples and compares beam readings is taught. Briefly stated, phototransistor readings (Q) which sample ambient light as well as light from an associated light emitting diode (CR) are compared with preset values. if the readings from the phototransistor are below a certain level, then the phototransistor/LED pair are flagged as bad. If the readings are within preset limits, yet below nominal values, then the phototransistor/LED pair are flagged as indicating a marginal beam. In this manner a trouble report may be generated for the purpose of repair or investigation as well as providing a vehicle for keeping a history of the opto-matrix frame condition and thereby a method of early fault detection.

Abstract: Abstract In a system for generating a vector representation of a waveform on a cathode ray tube screen, the minimum and maximum magnitudes of an analog waveform acquired during each of successive measurement periods are stored in a random access memory, with the minimum and maximum signal values for each measurement period being stored in arbitrary order.  The minimum and maximum signal values within each measurement period are then time sequenced by selectively comparing the minimum and maximum values obtained during each such measurement period with the values obtained during preceding and/or succeeding periods.  Also according to these selected maximum and minimum comparisons, the maximums obtained during selected measurement periods are decremented by a selected amount while minimums obtained during selected periods are incremented by a selected amount.  The waveform is then reproduced utilizing these ordered and selectively altered minimums and maximums to establish the coordinates on the screen of a sequence of vectors representing the waveform.

Abstract: ENVIRONMENTAL CUT-OFF FOR DEEP EXCAVATIONS                  ABSTRACT OF THE DISCLOSURE        High density polyethylene sheets are installed in panel forms to form an impervious barrier to fluid flow particularly corrosive contaminates and pollutants.  A slit is excavated in the earth under a bentonite slurry to the required depth.  A relatively thick, high density poly-ethylene sheet is placed in the trench and connected to two high density polyethylene pipes or channel members, the with of which, in the direction transverse to the direc-tion of the wall, is the width of the trench.  The panel length typically will be 15 to 30 feet.  Once the high den-sity polyethylene panel is installed, the slurry is dis-placed on both sides by a backfill material that can be a soil-bentonite, cement-bentonite or concrete.  A secondary panel section intermediate two previously formed primary panels is made using a secondary panel of high density poly-ethylene similarly constructed but using smaller diameter pipe or channel members than the primary panel pipes.  This panel is then lifted and the two smaller pipes or channels lowered into the primary panel pipes or channels with the high density polyethylene panel extending between through two slots or openings in facing primary panel pipe or channel elements.  A non-shrinking grout is then pumped into the pipe connection to form a tight joint.

Abstract: Abstract of the Disclosure Variable Leverage Recoil Mechanism Recoil spring mechanisms are useful, for example, in relieving excessive tension in the track of track-type vehicles.  Because the idler wheels recoil in a one to-one relationship against a recoil spring, the tension in the track still increases drastically from when recoil first starts to full recoil.  The subject variable leverage recoil mechanism has the idler wheel mounting bracket and first and second links arranged such that equal increments of movement of the idler wheel from a normal operating position toward a recoiled position results in progressively decreasing increments of compression of the recoil spring.  This results in the idler wheel having a progressivley increasing mechanical advantage over the recoil spring when the idler wheel move toward a recoiled position.
