Abstract: A bag filling apparatus attachable to a conveyance comprising a hopper having in connection therewith a plurality of bag filling chutes and including structure to selectively or simultaneously control the openings of the chutes.

Abstract: This invention relates to an interior drainage formed in a channel extrusion for a door frame insert having a combination of glass and screen members wherein the interior of the upper frame structure drains downwardly and the bottom horizontal member of the frame has an interior tiered construction which receives the moisture from above and has mitred corners whereby the respective tiers drain downwardly and underlying the ends of the bottom tier hidden from view are drain passages to the atmosphere.

Abstract: This invention relates to a peristaltic pump structure in which the improvement consists of provision for substantial adjustment in the size of the passage receiving a tube member and in providing for an external control of the positioning of the rollers to determine the desired pressure of passing fluid through the tube member prior to or during the course of the operation of the pump structure.

Abstract: An air cleaning device having a chamber receiving an incoming air stream wherein the improvement consists of the chamber progressively confining the incoming air stream to increase its linear and angular velocity and having an exhaust chamber receiving contaminants and isolating the same from the turbulence of the incoming air stream and a shield adjacent the dome of the device restricting the vertical clearance of the chamber receiving the incoming air stream.

Abstract: This invention relates to a protective circuit which senses and protects a current regulating battery charging circuit against the effects of reverse polarity and short circuiting originating with the battery being charged.

Abstract: A tapered substantially cylindrical housing forming an antenna structure to collect radiation as an emission from a human body and consisting of an antenna, the antenna forming a reflective liner having an upward taper relative to the housing becoming reduced to a small outlet passage in the neck portion of the housing, a sensing plate across the neck portion of the housing above the outlet passage, a shutter pivotal to overlie the outlet passage, a hood having a reflective lining extending upwardly of the housing and providing access to the sensing plate, and both the liner and the hood focus radiation onto the sensing plate.

Abstract: This invention relates to a glazing or insulating bead useable particularly with large commercial type glass building walls wherein the building wall frame structure embodies window frames, each frame has channels to receive a window pane, each channel has a pair of small opposed facing longitudinal sockets at its entrance and the glazing bead herein is particularly adapted to be non-stretchable in being disposed into one of the sockets either by being pulled thereinto or may be pushed laterally thereinto, in either instance, the glazing bead is particularly adapted not to be dislodged by the subsequent installation of a window pane.

Abstract: A broadhead arrow head structure armed with razor type blades spaced thereabout, each of the blades being positioned into a slot, each blade having an underlying forwardly projecting tongue portion, the tongue portions extending into an undercut recess of the slots, and the arrow head structure being threaded into an arrow shaft to lock the blades in operating position.

Abstract: A novel azeotropic mixture of the refrigerants R12, R22 and R142b in which a higher operating temperature and a lower operating pressure are attained than are attainable by any of the refrigerants of the mixture.

Abstract: An electric arc welding machine with a tiltable demountable welding head embodying a snap lock hinge structure providing for a tilted positioning of the welding head or for the ready removal of the tilting head for welding purposes remote from the base supporting structure.

Abstract: A rug and upholstery cleaning apparatus comprising a nozzle embodying a pair of chambers separated by a baffle elevated to provide a passage therebelow, one chamber comprising a suction chamber and the other a cleaning chamber having a jet directing a stream of cleaning fluid to the area of said passage and angled to penetrate and sweep through the pile of the material being cleaned to the depth of the soil therein, the combined action of suction chamber and pressure of the stream of cleaning fluid causing the pile to tend to become erect and aligned, and the suction in a simultaneous action with the injection of cleaning fluid causes the cleaning fluid to have a sweeping action through the pile and the suction withdraws the cleaning fluid with the soil therein to the extent that whereby what is substantially dampness remains in the pile.

Abstract: The method of analysis and corrective adjustment of a human body including scanning the body, and particularly the spinal column area, by an appropriately tuned radiometer to collect and display measured microwave emissions for detection of areas of stress such as may be present in connective tissue, nerve tissue or muscular tissue, the scanning permitting an analysis of subcutaneous microwave emissions from depths up to several centimeters, converting the collected emissions into a visual measured output, comparing the resulting output to a reference representing a normal range of emissions and observing during the application of corrective adjustment, the extent of correction being provided as changes displayed in the collected emissions are compared with the reference of a normal condition and noting through the application of corrective adjustment pressure in several radial directions, the particular radial direction in which the application of pressure secures the maximum reduction in deviation from said

Abstract: An apparatus for cleaning hard surfaces and surface coverings such as rugs and upholstery material, consisting of a tank of cleaning fluid, an outlet line running to a cleaning head, a pump in connection with the outlet line, a vacuum motor with an inlet line recovering cleaning fluid through the cleaning head, filters in the tank in connection with the inlet and outlet lines, a stream cleaning the outlet filter and centrifuging the cleaning fluid in the tank separating out contaminants leaving a body of cleaning fluid substantially free of particulate matter to recycle whereby for example, a tank of six gallons of cleaning fluid can accomplish the effective cleaning effort for which would be required on the order of sixty gallons of uncycled cleaning fluid.

Abstract: A floor covering, as for indoor public walking areas, being made up of sections, each section being substantially rectangular in plan, having a fairly narrow width and being disposed in closely spaced parallel relationship. Coupling members not unlike double hinges connect adjacent sides of the sections, the coupling members being particularly arranged to permit a compact rollup of the sections for cleaning purposes.
