The do-all machine, briefly described, comprises a vehicle frame designed around an underbelly conveyor having crop clearance therebetween, and a pair of opposite hand implement support booms carrying belt conveyors which feed crops laterally onto the underbelly conveyor. The underbelly conveyor moves the crop underneath the frame of the machine to another vehicle following behind the agricultural do-all machine.

Abstract: It has been discovered that refractories at their elevated use temperatures have electrical properties unique to semi-conductors. The electrical conductivity of refractories is changed by altering the defects in the metallic or nonmetallic ions of the refractory lattice, and the purity is controlled to prevent fluxing from occurring at the grain boundaries. The discovery makes possible either the increase or decrease in electrical conductivity of any semi-conducting refractory, since the theory is applicable to both materials wherein the defects occur in the metal ions of the refractory lattice and also to materials wherein the defects occur in the nonmetallic ions of the refractory lattice.

Abstract: A method of making molding compounds and particularly sheet molding compounds in which a novolak is dispersed throughout an inorganic filler and a slight reaction is caused to take insitu with a hydrogen donor that is preferably hexamethylenetetramine to produce a molding compound. In the case of a sheet molding compound, the material is spread out into a thin sheet and inorganic fibers are embedded therein, following which a body-building reaction is initiated to liberate some ammonia. Thereafter, the material is dried and solidified into a solid handleable sheet molding compound.There is also disclosed a method for forming the novolak resin insitu by reaction of the monomers while dispersed throughout the inorganic fillers.

Abstract: A scratch resistant, flame resistant material is made by producing a sheet molding compound of a melamine-aldehyde precondensate, silica, alumina trihydrate, slightly soluble soap, ammonium hydroxide and acid salt catalyst. The sheet molding compound is applied to the surface of a pelt of glass fibers containing a heat curable binder and the composite is bonded together under heat and pressure to cure both binders simultaneously and bond the sheet molding compound to the fiber layer of the pelt.

Abstract: A stove having a combustion chamber surrounded by four sides and a top and having a warm air conduit extending between opposite sides and opening outwardly of at least one of the sides. Where the stove is to utilize natural convection, the conduits open outwardly of both the sides of the enclosure. An opening is provided in the top or bottom of the warm air conduit remote from its outlet or outlets for effecting draft thereto. A preferred embodiment has two such heating conduits at right angles to each other and with an opening therebetween to further increase draft through the conduits. In the case of forced convection, the conduits need only open from one of the sides.

Abstract: Halogen and amine groups attached to silicon are replaced by organocarboxylate groups. The replacement is carried out with the reactants dissolved in pentane. Substantially quantitative yields are obtained, and the reaction can be preceded or followed by other reactions carried out in the pentane media. For example, trichlorosilane is reacted with an olefinic unsaturate containing halogen in a first stage reaction. Thereafter the product of the reaction is reacted with an organic acid so that the chlorines attached to the silicon are then replaced by the organocarboxylate groups in a second stage reaction. The remaining halogen is then replaced by amine in a third stage reaction, all in the pentane media. All this is accomplished without an HCl scavenger.

Abstract: Method of producing plates having an identical configuration of valleys and lugs thereon so that one plate is interchangeable with another. Flat plates are provided with a pair of individual holes at opposite ends of the plate center line. Thereafter one or more valleys are machined in a predetermined spacing and location from one or both of the locating holes, and the process repeated for a plurality of plates. Lugs are produced by matching one plate with another by means of pins inserted into the locating holes, and injecting a hardenable material into the valleys. This hardenable material is bonded to the opposite plate. The machining operation of the valleys is carried out in a manner to produce randomly spaced ridges along the side surfaces of the valleys which form depressions in the side surfaces of the lugs that are cast therefrom. Molds made from the respective pattern plates have valleys with ridges therein which have an interference fit with respect to lugs of a matching mold.
