Abstract: ABSTRACT OF THE DISCLOSURE       Condenser apparatus for removing moisture from the air including a housing for the condenser apparatus, which housing has both a cooling liquid inlet and an air inlet at one end.  Within the housing is a rotatable disc downstream from the liquid inlet so that when the disc is rotated and liquid is impinged upon the disc a cooling liquid droplet cloud is produced.  At the opposite end of the condenser housing from the inlet is an air outlet and a concentrically positioned rotatable blower.  Located between the blower and the rotatable disc is a rotatable water wheel for collecting entrained liquid droplets before they pass into the blower.  Circumferentially around the rotatable water wheel is a liquid pump that removes liquid from the condenser apparatus.  An electric motor is utilized for rotatably driving all of the rotating elements.  An auxiliary liquid discharge outlet from the condenser appa-ratus is arranged to provide an air gap between the liquid inlet and outlet.  The condenser apparatus is utilized particularly in an automatic clothes dryer wherein hot moisture-laden air that has been passed over the fabrics to be dried is introduced into the condenser apparatus which reduces the temperature of the air to condense mois-ture therefrom and then recirculates the air again through the clothes dryer.

Abstract: ARTICLE CONVEYING                    Abstract Record medium containing articles are conveyed between a storage compartment wall, a read/write unit, and back to the storage compartment wall.  A movable accessing mechanism selectively fetches articles (tape-containing cartridges) from the storage compartment wall and inserts same into a horizontally disposed pivotable input apparatus.  The weight of the article in the input apparatus pivots it downwardly to a ver-tical position whereat the article leaves the input apparatus and enters a rotary conveyor.  The rotary conveyor is automatically indexed between input, work, and output positions.  The cartridge is indexed from the input to the work position of the rotary conveyor.          Thereat, a reciprocating rotatable idler shaft moves a spool from the cartridge into a read/write unit for transducing operations.  A single motor drives the con-veyor and reciprocating shaft.  On completion of the data processing operations, the spool is returned to the rotary conveyor, released from the idler shaft, and indexed to an output position.  The cartridge then falls into an output apparatus and is returned to the com-partment wall.

Abstract: ABSTRACT OF THE DISCLOSURE         A gyrocompassing system providing switch means with coarse align and gyrocompass modes of operation. Starting in the coarse align mode, a north bubble sensor output along with an initial vertical error signal output is applied to an east torquer which coarsely levels the east gimbal.  Subsequently, the switch means is placed in the gyrocompass mode and the signal from the north sensor is simultaneously applied to the east gyro and the azimuth gyro loops.  A voltage threshold detector deter-mines whether the signal from the north sensor requires low or high rate azimuth torquing.  If high rate azimuth torquing is required in the azimuth gyro loop, the east gyro loop is either locked or torqued at a high rate.

Abstract: ABSTRACT OF THE DISCLOSURE A liquid quenching system for use with continuous furnaces for heat treating small parts wherein the quenchant is used to both quench and convey the parts. A supply conduit connnects a quench liquid reservoir to a connector between the furnace and a quench chute providing an initial quantity of quench liquid in the quench chute. A feed conduit pumps additional quench liquid into the chute to convey the parts while they are being quenched to a segregating device comprising an inclined, rotating drum having an internal auger flight. The drum permits the return of clean quench liquid to the reservoir and moves the quenched parts substantially dry of quench fluid to a suitable receptacle or further conveying means. A portion of the quench chute forms a trunnion for rotatable support of the receiving end of the drum, the discharge end having a shaft mounted for rotation on the reservoir.

Abstract: Abstract of the Disclosure A method of producing impulse forces or shocks in one direction includes rotatably mounting a number of eccentric weights on a common support so that, prior to rotation thereof, the eccentrics are set in the direction of a desired shock.  The eccentrics are then rotated at different speeds with the ratio of each higher speed to the lowest speed forming a sequence of integers.  The rotation of the eccentrics induces centrifugal forces of de-sired value and a desired shock in one direction occurs in every phase of full revolution of the slowest eccentric weight.  The shock is the sum of the centrifugal forces created by all of the eccentric weights. The shocks or impulses produced can be used to compact various materials or to achieve a pressing effect.  They can be used in vibratory rollers and in mechanisms of a dynamic nature.

Thus, the suction conduit and the return conduit extend through and are both rigidly secured, as by welding, to the detachable cover member.  The respective suction and return conduits are adapted to extend down into the interior of the reservoir tank when the cover member is secured in overlying relation to the cover-receiving opening of the reservoir.  A baffle member is rigidly secured to the normally inner surface of the cover member in a plane substantially perpendicular to the inner surface of the cover to divide the interior of the reservoir into suction and return chambers, the baffle being so constructed as to permit fluid communication between the two chambers.  Each of the respective suction and return con-duits extends from its respective rigid connection to the cover member through the baffle member, each respective conduit being rigidly connected as by welding to the baffle to provide a reinforced construction for the cover subassembly.  A "breather" device is rigidly mounted on the normally outer surface of the cover member and is in gaseous communication with the interior of the upper end of the reservoir to maintain atmospheric pressure above the liquid level in the reservoir tank.  A com-bined fill tube and dip stick holder are also rigidly mounted on the detachable cover member.

Abstract: ABSTRACT OF THE DISCLOSURE Laboratory investigations in vitro of destruction and damage of living cells frequently involve labeling of the tissue cells in question with a radioactive isotope and subsequent dispersion of the cells in a suit-able liquid.  The dispersion is allowed to settle in a test tube, whereby a column of supernatant liquid is formed above precipitated cell particles. The radioactivity of said supernatant is considered a measure of cell destruct-ion and in order to measure the same completely separated from the precipi-tated cell tissue, the total amount or an accurately known fraction of the liquid must be collected, at the same time avoiding any collection of pre-cipitated particles.  In order to secure this it is suggested according to the present invention that an actively absorbing surface of a liquid absorb-ent body is immersed into said amount of liquid in the container with a filter permeable to said liquid, but not to said particles, completely covering said surface, and said amount of liquid is allowed to be completely absorbed by the liquid absorbent body through said filter, which subsequently is separat-ed from said actively absorbing surface before the absorbent body is removed from the container.  Utilising an absorbent body with sufficient absorbing capacity to assure a complete inclusion of the supernatant liquid in said body, with the exclusion of all cell particles by means of said filter, the total leakage of radioactivity from the cells to the liquid may be measured with high reliability by means of a subsequent scintillation counting.
