Abstract: Disclosed here is a novelly designed sandal whose vamp or sole can be changed. If there are many so designed vamps and soles, then many times new sandals can be composed by the interchange among the vamps and soles. For example, 5 different pairs of vamps and 2 different pairs of soles, then 10 different pairs of sandals can be made. The sandal can also be further changed by changing the binding, welt or side element with different color, type, etc.

Where an installation comprises several structures, the invention may also be used to control the wake from the more upstream, thus diminishing buffetting of the more downstream.

Abstract: Apparatus is disclosed which provides automatic height control for the header of a multi-row crop harvester. The crop processing header has a series of row dividers hinge mounted along its front edge. Under at least two of the row dividers is a ground engaging wheel which causes the leading edge of each to float up and down as the terrain changes. Servo actuating sensors mounted between the divider and the header respond to changes in the angle of attack therebetween. The servo system actuates hydraulic valves allowing oil pressure to automatically raise and lower the header. This means of height control maintains the cutter bar or ear stripper plates a predetermined distance above ground regardless of changes in terrain.

The baling chamber is normally closed at one end by a movable end wall and the drive means for the ram connects this end wall with the ram so that the end wall is held in closed position as the ram compresses material between it and the end wall.

Abstract: In a method of making carbon or graphite yarn, a bundle of single ply precursor yarns is knit into an elongated fabric to facilitate subsequent processing of the yarns. The elongated fabric is pretreated to facilitate carbonization thereof such as by being advanced in the direction of elongation thereof through a cleaning process. Thereafter the yarns remain in the form of the fabric to facilitate processing thereof through at least a carbonization step. The carbonization step may be accomplished by winding the elongated fabric onto skeins to a desired extent and then severing the fabric, following which the skeins are disposed in a carbonizing oven to at least partially carbonize the yarns. Thereafter, the fabric length on each skein may be deknitted, and the resulting bundle of single ply yarns is twisted to form a multi-ply yarn which is then fired to substantially raise the percentage of carbon in the yarns and then graphitized.

Abstract: This invention relates to a process for the efficient production of power by the oxidation of carbonaceous or hydrocarbon fuels with minimal pollution of the atmosphere. In one of its more specific aspects, this object is accomplished by partial oxidation of the hydrocarbon or other carbon-containing fuels to produce a fuel gas, followed by partial oxidation of this fuel gas and finally complete combustion of the gaseous products of the second partial oxidation with the generation of power in stages following each of the oxidation steps such that the stack gas discharged to the atmosphere is low in oxides of nitrogen and is substantially free from sulfur compounds. The process is particularly suitable for use with sulfur-containing petroleum residua, shale oils and the like.
