An interseeder apparatus and method for dry broadcast distribution of seeds in conjunction with a center-pivot irrigation system. The interseeder apparatus comprises a storage container for storing a quantity of dry seed to be interseeded. The storage container is adapted to be mounted on a center-pivot irrigation system. A seed conveying device is employed for conveying the seed in a dry condition from the storage container outwardly from the storage container. A plurality of dispensing stations are positioned along the main water pipe. Each of the dispensing stations has a seed box for containing a quantity of dry seed, a discharge opening, seed delivery device in communication with the seed conveyer device for delivering a quantity of dry seed from the seed conveyer device into the seed box from the seed conveying device; seed metering device for regulating the discharge of seed from the discharge opening of the seed box; and distribution device in communication with the seed box for receiving seed discharged through the discharge opening by the metering device and broadcasting the seed therefrom. Finally, the apparatus has a device for activating the seed metering device and the distribution device, such that upon activation, a quantity of dry seed is discharged from the seed box and delivered to the distribution device for broadcast distribution.

Interseeding apparatus and method

There is disclosed herein a refrigerant container in the form of a bag, or pouch, made from two sheets of multi-layer barrier film material which are heat sealed adjacent their edges to form a closed pouch which has an interior space. The bag may be connected to an access valve provided in a line of a sealed refrigeration system for capturing the refrigerant therefrom. The barrier film material is specially formulated to prevent outward permeation of a refrigerant and to prevent inward permeation of air. A valve system is provided for filling and emptying the bag.

Method and apparatus for recovering refrigerants from home refrigeration

There is disclosed herein a refrigerant container in the form of a bag, or pouch, made from two sheets of multi-layer barrier film material which are heat sealed adjacent their edges to form a closed pouch which has an interior space. The bag may be connected to an access valve provided in a line of a sealed refrigeration system for capturing the refrigerant therefrom. The barrier film material is specially formulated to prevent outward permeation of a refrigerant and to prevent inward permeation of air. A valve stem is provided for filling and emptying the bag.

A method and apparatus for bonding two tubes in a refrigeration sealed system by soldering. The apparatus includes a pair of jaws which are spring biased in the closed position and a pair of handles for opening the jaws against the spring bias force. The jaws include electrodes having arcuate recesses therein which are arranged in opposed facing aligned relationship so that a pair of tubes may be held between the electrodes. One of the pair of tubers to which the method is applied has a flared end with a larger diameter than the other tube. The ends of the tubes are first cleaned by mechanical means and flux is then applied to the end of the smaller tube. The end of the smaller tube is then slid into the flared end of the other tube in telescoping registry and the telescoped ends are clamped between the electrodes. A solder ring is then positioned around the smaller tube into abutting relationship with the flared end of the other tube. Electric current is supplied to the electrodes to heat the telescoped tube ends so that the flux will melt and cause it to further clean the tube ends. The heat will also melt the solder which is then drawn into the interface area between the telescoped tube ends.

Method for repairing a refrigeration sealed system

An improved corrosion-inhibiting system for use in heat pipes operating at relatively high temperatures, such as 300.degree. F. to 500.degree. F. In the illustrated embodiment, a corrosion inhibitor aqueous solution is provided having approximately 1% to 5% by weight sodium chromate. Glass which goes into solution into the sodium chromate at temperature of approximately 300.degree. F. and above is included in the system. The solution of the glass in the sodium chromate solution permits the glass to be carried to the condenser portion of the heat pipe in small solution droplets which are transported by the vaporized fluid so as to be adsorbed in the protective layer on the inner surface of the heat pipe tube. Glass dissolved in the boiling liquid solution is adsorbed on the wall surface in the evaporator portion of the heat pipe. Pyrex glass has been found to provide excellent results in the system.

Method and means for inhibiting corrosion in a heat pipe

An improved wet oxidation process for oxidizing an aqueous dispersion of organic matter under heat and pressure utilizing a manganese oxide containing catalyst. A supported manganese oxide containing catalyst structure is provided.
