Patent for reinforcing the hinge of an antiskid device. Long studs on heavy foot plates on tires are used to brace the hinges not allowing them to wear down by dragging on the road surface.

Patent for a device that will clean drill bits used for wells without needing to remove them from the ground. Additional aspects of the patent cover fittings and attachments necessary for better operation of the drill bits and the cleaner.

Patent for an improved Compound Air-Compressor by having four cylinders, in pairings of a high pressure and a low pressure cylinders. The air from the low pressure cylinder will be fed to the high pressure cylinder. The pistons will work in succession rather than simultaneously.

Scientific paper issued by the Bureau of Standards over studies conducted on radio fading. As stated in the abstract, "the series of measurements on fading were devoted to studies of fading effects during the sunset period, effects during the solar eclipse of January 24, the fading variations throughout a 24-hour day, and the effects of high transmitting power on fading" (p. 419). This paper includes tables, maps, illustrations, and photographs.

"This report gives the results of the second portion of an investigation in the twenty-foot Propeller Research Tunnel of the National Advisory Committee for Aeronautics, on the cowling and cooling of a "Whirlwind" J-5 radial air-cooled engine. The first portion pertains to tests with a cabin fuselage. This report covers tests with several forms of cowling, including conventional types, individual fairings behind the cylinders, individual hoods over the over the cylinders, and the new N. A. C. A. complete cowling, all on an open cockpit fuselage. Drag tests were also made with a conventional engine nacelle, and with a nacelle having the new complete cowling" (p. 191).

From Summary: "In Technical Report no. 247 of the National Advisory Committee for Aeronautics theoretical formulas are given from which was computed a table for the pressure of air on coming to rest from various speeds, such as those of aircraft and propeller blades. In that report, the table gave incompressible and adiabatic stop pressures of air for even-speed intervals in miles per hour and for some even-speed intervals in knots per hour. Table II of the present report extends the above-mentioned table by including the stop pressures of air for even-speed intervals in miles per hour, feet per-second, knots per hour, kilometers per hour, and meters per second."

Part I gives a general method for finding the steady-flow velocity relative to a body in plane curvilinear motion, whence the pressure is found by Bernoulli's energy principle. Integration of the pressure supplies basic formulas for the zonal forces and moments on the revolving body. Part II, applying this steady-flow method, finds the velocity and pressure at all points of the flow inside and outside an ellipsoid and some of its limiting forms, and graphs those quantities for the latter forms. Part III finds the pressure, and thence the zonal force and moment, on hulls in plane curvilinear flight. Part IV derives general equations for the resultant fluid forces and moments on trisymmetrical bodies moving through a perfect fluid, and in some cases compares the moment values with those found for bodies moving in air. Part V furnishes ready formulas for potential coefficients and inertia coefficients for an ellipsoid and its limiting forms. Thence are derived tables giving numerical values of those coefficients for a comprehensive range of shapes.

This paper present a description of the method employed and results obtained in full-scale turning trials on the rigid airship U. S. S. "Los Angeles". The results of this investigation are not sufficiently comprehensive to permit definite conclusions as to the variation of turning characteristics with changes in speed and rudder angle. They indicate however, that the turning radius compares favorably with that for other large airships, that the radius is independent of the speed, that the position of the point of zero yaw is nearly independent of the rudder angle and air speed, and that a theoretical relation between radius and angle of yaw in a turn gives a close approximation to actuality.

Patent for a new device that improves lawn mower sharpeners, including illustrations. It is a detachable device that attaches directly to the lawn mower and sharpens the blades while in use.

Patent for a nut lock that secures two nuts of a pair within a tubular casing through opposing threading and rotation, where one nut is immobilized and the other remaining adjustable to meet situational need. Illustrations included.

Patent for an instrument to determine a level at widely distant points or determining inclinations and which may be correctly read under conditions where a level cannot be held erect. Also known as hydrostatic leveling, this instrument is comprised of flexibly connected liquid containers that are spaced apart at certain distances.

Patent for a tractor turning mechanism that will allow tractors to turn at any angle up to a right angle by locking one of the driving ground wheels into a pivot point for the other wheels of the tractor.

Patent, including illustration, for "a musical instrument slide and is more particularly designated as a bearing or stocking for a trombone or other similar instruments in which it is desirable to provide a smooth bearing for the slidable part of the instrument" (page 1, lines 9-13).

Patent for a sod cutting and disintegrating machine that has a wheel-supported frame, inclined elevator, plow attached to the elevator, front truck, and disintegrating rollers.

Patent for a hand harvester that contains a plate and cutter to be used for harvesting corn and maize with more ease.

Patent for steam gauge or test cocks that provides a simple and economical gauge cock for steam boilers by which the steam can be readily tested and which is adapted to close the orifice automatically to provide a constructions which will not be disarranged in operation.

Patent for new and useful improvements in electrical testing devices. The invention provides references to innovative changes that allow for improved high-tension coil and armature testing.

Patent for a device to test electrical circuits for faults which is cheaper to manufacture, easier to use, smaller and more durable.

Patent for improvements to piston rings to reduce leakage through piston grooves, rings, and joints.

Patent for a steering attachment that keeps the steering wheels of a motor driven vehicle straight. This device is simple and relatively inexpensive, among other advantages.

Patent for rotary razors that includes a rotating blade that approaches and passes over the skin to avoid cuts or scrapes. The blade on the razor is tilted too far out to cause cuts and scrapes, yet it provides a sufficient shave.

Patent for a machine used in the wet milling process. It allows proportionate distribution of liquids to aide during the thickening process.

Patent for the improvement of the shovel plow. The improvement of the shovel plow allows for the adjustment of the plow height as needed.

Patent for the improvement of existing rail joints by creating a tie or bond at the end of rails to allow them to lock together. The improved rail joint will make the use of bolts and nuts, or other connectors unnecessary when connecting rails.
