Abstract: A system for sequential tubular administration of first and second fluids including a first reservoir to contain a first solution, e.g., a solution of medication; a second reservoir having less capacity than the volume of solution in the first reservoir with an overflow chamber. The two reservoirs are in communication with each other, and both are provided with valved solution discharge lines, the entrance to which is provided with a ball float valve. The two discharge lines meet at a wye connection having an infusion feed assembly at an outer free end of same. With a first solution in the first reservoir and with both reservoirs closed to the atmosphere, second solution, e.g., I.V. solution may be fed into the second reservoir which displaces air therefrom into the first reservoir to assist in feeding solution from the first reservoir.

Abstract: An improved temperature-responsive wall ventilator construction comprising a housing having side walls defining an air flow passageway, a plurality of louvers disposed in said passageway and operatively attached to opposed side walls of the housing for pivotal movement to control the flow of air through the passageway. A temperature-responsive bimetallic coil spring located in the passageway and in an opening through one of the louvers controls pivotal movement of the louvers in the passageway to regulate the flow of air therethrough. One end of the coil spring is mounted directly to a face of one of the louvers, and the other end portion of the coil spring extends into an opening in a side wall of the housing to serve as sole pivotal support for one end of the louver. Temperature changes cause expansion and contraction of the spring which causes corresponding pivotal movement of the louver.

Abstract: A method for producing graphic or mathematical boundary information, in the form of graphs and the like, and the use of such information, for more accurately predicting the acidity and alkalinity of water drainage from rock types which may be subjected to weathering conditions in earth moving operations.Selected rock samples of particular rock types collected from a geographic location of interest are subjected to oxidation and leaching for a predetermined period of time to simulate natural weathering conditions to which the rock types may be exposed. The leachates from each rock sample are chemically analyzed by titration with standard acid and base solutions to selected end points to obtain their acidity or alkalinity concentrations, and these concentrations are differentiated for the particular rock sample to obtain a net acidity or alkalinity value for the rock sample.

Abstract: Static tow inverting apparatus for inverting the overlap of overlapping layers of a continuous length filamentary tow band of textile material deposited onto the surface of a moving conveyor in relaxed condition for treatment, such as in the thermal heat setting treatment of a band of tow which has been subjected to a mechanical crimping operation. The tow inverter comprises a pair of stationary plates which are disposed above the surface of a moving conveyor to receive a continuous length of tow in a plurality of overlapping layers thereon. The opposed surfaces of the spaced plates define a downwardly curving passageway for gravitational conveyance of the overlapping layers of tow through a reversing direction of movement to deposit the same on the surface of the moving conveyor with preceding layers of tow overlying succeeding layers of tow in the direction of movement on the conveyor.

Abstract: A process for recording and projecting a three-dimensional visual scene onto a receiving surface from which the scene may be viewed in stereopsis by the unaided human eye. The scene is recorded from right and left view positions laterally separated by a distance of no more than about one inch, and groups of recorded right and recorded left views are alternately projected onto a receiving surface in sequence such that the visual duration of each group varies from a minimum to a maximum time which is generally proportional to the distance of the nearest non-moving object of special regard in the scene from the recording positions and is approximately equal to the visio-psychological suppression rate of the human eyes.

Abstract: A corn buttering device for applying a coating of butter or butter substitute to an ear of corn comprising a pan for containing a heated liquid and a receptacle mounted in the pan for containing liquid butter. The pan is provided with a cover which has a recessed upper surface for receiving and supporting an ear of corn therein. The recess in the cover is provided with an elongate slot which communicates with the butter receptacle when the cover is moved downwardly to tilt the receptacle and cause butter to pour through the recess slot and contact an ear of corn. The recess slot is normally closed by a movable wall member which is displaced from the slot during downward movement of the cover on the pan. The cover containing an ear of corn therein is maintained in an upper position on the pan until manually displaced to a lowermost position for applying butter to the corn.

Abstract: A device is disclosed for tensioning a running length of textile yarn. The device contains a yarn passageway made up of three sections, each section having a progressively larger diameter from the inlet end of the device. A small diameter section at the entrance end of the device has a seat adjacent the inner end thereof which receives a spherical element. The medium diameter section surrounds the seat and retains the spherical element therein. The larger diameter section of the passageway is sufficiently large to enable pressurized air to pass around the spherical element without forcing the element out the end of the passageway. The wall adjacent the junction of the large and medium diameter sections is tapered so as to permit ready return of the spherical element to the medium diameter section to reside on the seat. Mounting means are also provided for securing the device to a yarn handling machine.
