Abstract: A manufacture of uniformly sized doors for the compartments of safe deposit box nests comprises punching the lock nose holes in uniformly oversized door blanks and then using those holes as the reference from which the various operations on the edges and rear faces of the blanks are performed. For the latter purposes the blanks are supported in a vertical position upon special moving workholders which engage and position the blanks by means of reciprocating draw bars which extend through the nose holes. In cooperation with other apparatus, the draw bars releasably clamp the blanks in position while various machine operations are serially performed on the blanks as the workholders pause at successive tool stations.

Abstract: A grain dryer employs an auger assembly featuring a hollow auger shaft through which hot water is circulated to heat the auger flighting and thus the grain. The water emerging from the auger shaft is then used to heat atmospheric air supplied by a blower, which air is then injected into the grain through a set of ports along the auger housing. The injected air entrains moisture expelled from the grain by the hot auger and exits from the auger housing through another set of ports along the latter.

Abstract: A method of breeding yellow dent hybrid seed corn by causing pollination of the silks of an ear other than the top ear of the corn plant with the resulting fertilization of the lower ear. The method is accomplished by causing the ear shoot at the top of the plant to abort before the silks emerge from that shoot, and then allowing a lower ear to produce silks and receive pollen from the male seed parent. Fertilization of the second or lower ear is then accomplished resulting in a corn plant that provides seed (F.sub.1) which will in turn produce a higher yield in the farmer's field. (F is the designation of generations of plants, F.sub.1 being the first filial generation.

Abstract: An implant gun for depositing pellets or the like subcutaneously. The gun includes a hollow needle through which a number of pellets are dispensed from a cartridge that is positioned either inside the needle or in an ante-chamber. The action of the gun is such that the pellets are gently deposited in the tissue as the needle is withdrawn from the cavity formed in the tissue at the time the needle was inserted. This technique practically eliminates any breaking of the fragile pellets and reduces the trauma of their insertion into the tissue. The implant gun also includes a unique ram activating mechanism that frees one of the hands of the operator so that the implanting procedure can be conducted without assistance. The implant gun is also easily adapted for use in implanting single items other than pellets, such as identification tags for animals.

Abstract: A removable bezel grinding attachment for a dop stick holder features a bezel table for support of a cabochon, the table replacing the dop stick of the holder, and means for adjusting the inclination of the table.

Abstract: A safe deposit box nest includes an outer housing into which are assembled a number of sheet metal partitions and shelves to form compartments. In order to eliminate the need for individually fitting each compartment door, each such door is hinged to and strikes against posts formed by extruded members such as aluminum attached to the front of the partitions. To the same end the forward edges of the shelves are disposed between the posts and doors and are folded rearwardly upon themselves and compressd to form shelf edge portions of uniform thickness. Finally, the nest is constructed in a manner which reduces welding to a minimum and helps insure accurate and uniform compartment openings to which the doors are applied.

Abstract: A device for treating swollen surface areas on horses and the like consists of an elongated envelope-like receptacle which is supplied with water. One side of the receptacle is equipped with water outlets and faces the affected area for discharge thereon, the device being supported in position from the body of the animal itself.

Abstract: An attachment for a conventional level-land grain combine which allows the combine to be operated and the grain to be harvested on the slopes of hillsides without excessive buildup of the grain on the low side of the machine. The attachment includes movable doors which vary the size of the opening between the gathering and cutting unit and the feeding and separating unit. By partially closing off the opening on the low side of the machine, more of the grain is fed to the high side thus providing for more even distribution of the grain into the threshing and separating units. Movement of the doors is remotely controlled by the operator according to the slope of the hillside on which the machine is operating.

Abstract: A jig for the cutting of proximal boxes or outline forms in dentistry employs a guide table and paralleling arm. The guide table is located over the teeth by the clamping action of a pair of depending retentive arms which engage the embrasure area between adjacent teeth. The paralleling arm, which receives the dental burr, is swingable over the guide table and the latter and the arms in turn are provided with guide surfaces for determining the location and attitude of the buccal, lingual, axial and cervical walls of a proximal box.

The annular gear has such a special relationship to the weights and gear hub, that the act of clamping the weights in place on the gear hub simultaneously clamps the annular gear in place.

Abstract: A method of hot mix recycling of old asphaltic concrete paving heats the old pavement, after it has been removed and sized, to a temperature below its firing point and heats fresh aggregate to a greater temperature before combining the two and adding new asphalt. The method is embodied in a drum-mixer type of apparatus modified by inserting a smaller drum in the upstream portion of the large drum. The burner fires into the smaller drum into which the fresh aggregate only is introduced while the old mix (plus additional fresh aggregate in certain cases) is introduced into the annular space between the two drums, the fresh aggregate and the old mix being thereafter combined in the large drum, new asphalt added and the mix further heated.

Abstract: An apparatus that facilitates the manufacture of wooden stairs of the type having treads and risers extending between and affixed to side housings or stringers. The apparatus provides multiple, parallel guides for the router used to cut the grooves in the stringers into which are fitted the treads and risers. By using a parallelogram construction for the multiple guides, the apparatus can be quickly adjusted and set to produce almost any size of stairs. An index bar used with the apparatus allows the apparatus to be quickly set for the particular stairs desired so that the grooves for both the treads and risers can be cut quickly and accurately in the stringers. The router is moved along each of the parallel guides to cut the grooves for all of the treads, and then the apparatus is quickly and easily reset and locked into position to set the guides for cutting of the grooves for the risers.
