Abstract: A cooling vest having a plurality of elongated pocket partitions formed on front side and backside vest portions for containing beads of polyacrylamide material that absorb a liquid, such as water, to form a gel that may be chilled, or frozen, to provide a cooling effect on the upper torso of a human wearer. The cooling effect is facilitated by non-impervious properties of a double layer fabric used in construction of the vest that permit evaporation. The front side portions of the vest also provide surface area upon which to add fashion appeal ornate designs, or on which utility pockets are formed. The vest is further provided with a collar member having a partition for containing polymer material. The upper shoulder blade area of the backside of the vest is divided from the lower lumbar area by a stitching pattern that ornate the backside of the vests and that separates the upper and lower polymer containing partitions.

Abstract: A double backer for curing the web bonding adhesive and drying the corrugated paperboard web utilizes a web holddown apparatus for maintaining the web in intimate drying contact with the lower heating units which does not require the use of a driven holddown belt. The holddown is provided instead by a series of parallel, flexible, closely spaced strips suspended above the web in the heating section and extending in the direction of web travel. Supplemental holddown force may be provided by banks of spring fingers supported above and in contact with the holddown strips on a transverse support rod which may be rotated to vary the amount of supplemental holddown force. Alternately, the holddown strips may comprise continuous cables in which one run of the cables rests upon the moving web to provide the web holddown and a second run includes high friction cable portions which are movable into driving contact with the upper surface of the web to pull it through the heating section, as for initial web thread up.

Abstract: Method and apparatus are disclosed for separting a refrigerant from oil and/or impurities contained in components of a compressor cooling system. When retrofitting a compressor cooling system using a CFC refrigerant into use of a chloride HFC refrigerant, the mineral oil mixed into the CFC refrigerant has to be seperated. It is thereby a problem that the oil is spread in all the components of the system and that existing cleansing technique is not efficient, since it does not cleanse all the components as the technique used involves that some of the components are by-passed. According to the invention these problems are solved by temporarily connecting an oil removal device in series with the compressor cooling system without having to by-pass any components. The compressor cooling system is filled with refrigerant, e.g. R134a.

Abstract: A dryness control circuit for a household clothes dryer including a power supply circuit and a moisture sensing circuit. The power supply circuit converts high voltage AC power into low voltage, DC power. The low voltage, DC power is supplied to the moisture sensing circuit. The moisture sensing circuit includes a moisture sensor having a pair of spaced-apart electrodes, a time delay circuit, an electrostatic discharge attenuation circuit, and a motor controller circuit. The motor controller circuit includes a control hysteresis or dead-band in which operation of a timer motor is unaffected. The time delay circuit includes an RC network which slowly charges and discharges to prevent erroneous dryness or moisture readings, which are sensed by the moisture sensor, from causing the motor controller circuit to improperly actuate or deactuate the timer motor. The electrostatic discharge attenuation circuit negates the deleterious effects of static build up.

Abstract: A chicken manure drying system is placed in a hen house. A platform of the system is disposed underneath a plurality of chicken cages. As chicken manure drops from the chicken cages, it collects on the platform. Drying fans of the system are disposed adjacent to the platform. The drying fans provide a constant flow of air over the chicken manure so as to dry the chicken manure. The plowing apparatus of the system includes a plowing device disposed over the platform. The plowing device is periodically moved across the platform in order to plow the chicken manure. The plowing of the chicken manure exposes more of the chicken manure to air. This exposure facilitates the comprehensive and expeditious drying of the chicken manure. After the chicken manure has been sufficiently dried to serve as fertilizer, the chicken manure is conveyed to a collection site.

Abstract: The generation of volatiles from liquid or solid materials is enhanced and accelerated by exposure to microwave radiation. Normally the energy transfer is effected preferentially toward the liquid or solid materials over the generated gaseous volatiles. Sufficient energy is provided at a selected rate that enhances the generation of volatiles to effect removal as vapor or to produce a pressurized vapor phase. Flow-through separations from a matrix having a microwave-absorbing liquid component are conducted by exposing to microwave radiation to vaporize this component and processing the vapor either by flowing through a selective permeable membrane, or by enclosing the vapor and matrix in a confined space and flowing matrix through a selected separation medium, and recovering residual matrix. These separations are particularly useful in analysis contexts.

F. (93.degree. C.) to 400.degree. F. (205.degree. C.) by a gas flame or other heat source, the adsorption and desorption phases being changed between the zeolites in each cycle by reversing the fluid flow in the conduits. Cooling and heating for a building or other purposes are provided through the condenser and evaporator respectively for the working gas (water) which is desorbed and adsorbed into the zeolites.
