The invention is a dust feed device for delivery of a uniform supply of dust for long periods of time to an aerosolizing means for production of a dust suspension. The device utilizes at least two tandem containers having spiral brushes within the containers which transport the dust from a supply to the aerosolizer means.

A method of vitrifying soil at or below a soil surface location. Two or more conductive electrodes are inserted into the soil for heating of the soil mass between them to a temperature above its melting temperature. Materials in the soil, such as buried waste, can thereby be effectively immobilized.

A radioactive hot cell access hole decontamination machine is disclosed. A mobile housing has an opening large enough to encircle the access hole and has a shielding door, with a door opening and closing mechanism, for uncovering and covering the opening. The housing contains a shaft which has an apparatus for rotating the shaft and a device for independently translating the shaft from the housing through the opening and access hole into the hot cell chamber. A properly sized cylindrical pig containing wire brushes and cloth or other disks, with an arrangement for releasably attaching it to the end of the shaft, circumferentially cleans the access hole wall of radioactive contamination and thereafter detaches from the shaft to fall into the hot cell chamber.

Coal (or other carbonaceous matter, such as biomass) is converted into a product gas that is substantially free from hydrocarbons. The coal is fed into a solar reactor, and solar energy is directed into the reactor onto coal char, creating a gasification front and a pyrolysis front. A gasification zone is produced well above the coal level within the reactor. A pyrolysis zone is produced immediately above the coal level. Steam, injected into the reactor adjacent to the gasification zone, reacts with char to generate product gases. Solar energy supplies the energy for the endothermic steam-char reaction. The hot product gases flow from the gasification zone to the pyrolysis zone to generate hot char. Gases are withdrawn from the pyrolysis zone and reinjected into the region of the reactor adjacent the gasification zone. This eliminates hydrocarbons in the gas by steam reformation on the hot char. The product gas is withdrawn from a region of the reactor between the gasification zone and the pyrolysis zone. The product gas will be free of tar and other hydrocarbons, and thus be suitable for use in many processes.

Patent for filling bottles with "two liquids and introducing them into the bottle at the same time under pressure" (lines 17-18), specifically for "carbonated beverages" (lines 12-13).

Patent for an improved attachment for the lathe to grind cylinders of different sizes

Patent for the development of a drill bit "specially designed for the purpose of obtaining samples of the formation through which the drill bit is passing" (lines 14-16).

Patent for an improved electric switch that is used to energize electric lights for various purposes and for use in connection with a signaling system. This switch will permit the energization of any one of the lights separately or all lights simultaneously.

Patent for a fiber cleaning device, which removes "the outer fleshy or non-fibrous tissues covering the fibers" (lines 19-21) for varieties of fleshy plants.

Patent for a new device that secures chairs to the floor and is easily detachable so the chairs can be moved when necessary.

Patent for a new and improved nut-locking device to securely lock fish plates to rail ends.

Patent for a spring wheel. Gebhardt describes the wheel as "an improvement... to provide resilient spokes which are connected to the hub and felly of the wheel in a manner to take up vibration and shocks imparted to the wheel in traveling or passing over obstructions and rough roads (p. 1, lines 8-15)." The patent also adds provisions for easy removal of spokes and a sectional felly and hub.

Patent for a tool to cover a portion of barbed wire fence allowing one to cross over or through without harm, composed of three or more telescoping metal tubes.

Patent for a window shade hanger device which allows for the shade to be placed at multiple stations by sliding and covering any portion of the window desired instead of a stationary shade mount.

Patent for a railway car replacer, which is used to derail vehicles as well as for, "restoring derailed railway vehicles to the track."

Patent for a cotton picking machine. An improvement on the cotton picking machine that uses a pair of picking drums with attached picking fingers.

Patent for a fan actuating mechanism. Attempts to improve upon fans by using a spring to provide maximum speed at minimum cost.

Patent "relates to improvement in wash basins, tubs, sinks, trays, and the like and especially with reference to the provision of improved means for flushing the waste pipe or duct thereof and for preventing overflow in the case the supply of faucet or faucets should be left running..."

Patent for a new type of motor. The aim of this new type of motor is to use head and cold to expand and contract the bar used to apply power.

Patent for improvements in parcel carriers for bicycles in which the parcel carriers can attach/detach easily and is adaptable to different types of bicycle handlebars; includes illustration.
