Abstract: A process for the treatment of glass to modify various properties thereof. The process comprises the steps of applying a coating of at least one metal, preferably by vapor deposition, onto the surface of a SiO.sub.2 containing glass. The coated glass is thereafter heated to a temperature sufficient to cause the metal to migrate from the surface of the glass into the glass without any residue or coating remaining on the surface of the glass.

Abstract: A fluid-cooled smoking device includes a housing for containing a liquid coolant, and a tubular member projecting into the housing for supporting a smoking bowl-ash receptacle assembly disposed upon and with the tubular member. Concentric tubular members within the ash receptacle portion of the assembly define a serpentine flow path whereby the smoke and fumes to be inhaled are initially air-cooled, and subsequently, the air-cooled smoke and fumes pass into the liquid coolant so as to be liquid-cooled prior to reaching the smoker. The ash receptacle accumulates burnt tobaccos and ash deposits and prevents the same from entering the liquid coolant whereby the latter remains clean for extended periods of time.

Abstract: Compositions useful for the repair of depressed cutaneous scars comprising at least one fibrin stabilizer and plasma in an amount to provide sufficient fibrin within a cavity formed under the scar. The fibrin stabilizer or a mixture thereof is present in an amount effective to maintain the fibrin within the cavity and thereby cause the build-up of collagen within the cavity. A preferred composition comprises pulverized absorbable gelatin sponge and aminocaproic acid, or derivatives thereof, with plasma being used in combination thereof or permitted to flow naturally into the cavity immediately after the formation thereof. Methods for repairing depressed cutaneous scars including the step of introducing said compositions intradermally beneath the scar are also disclosed.

Abstract: A cyclone structure is provided for use in controlling the flow of two fluid streams to create a localized inward radial flow. The structure includes a chamber having a side wall disposed concentrically about a longitudinal axis and having first and second transverse end walls attached to respective ends of the side wall. A discharge tube is mounted in the first end wall concentrically about this axis and projects into the chamber. First and second inlets are provided adjacent the respective end walls and means is provided to move fluid under pressure into these inlets and into the chamber. The fluid enters the chamber in two distinct fluid paths moving vortically about the axis in the same direction of rotation, and the respective energy flow rates of fluid in these paths are comparable. The paths are generally vortical within the chamber and progress axially towards one another before combining where they meet to create the localized inward radial flow.

Abstract: Various dialkylammonium-2,4-dichlorophenoxyacetates having the formula ##STR1## wherein R.sub.1 and R.sub. 2 are radicals each selected from the group consisting of methyl and ethyl, are useful as plant growth regulators. Mono-substituted alkylamines are not suitable for processing into compounds of this invention. The compounds of the invention exhibit excellent water solubility characteristics and possess an exceptionally high and unexpected degree of effectiveness as a general weed killer on lawns, pasture lands, ponds, lakes, canals, ditches, etc. Methods of using and preparing these compounds are disclosed.

Abstract: A method of producing an atmosphere suitable for plant growth and providing an atmosphere comprising the steps of supplying hot flue gases, cooling the flue gases to condense the water vapor contained therein, allowing said condensed water vapor and the flue gases to remain in intimate admixture for a time period sufficient for the condensed water vapor to absorb at least a portion of the flue gases and promote inter-reaction, spraying the condensed water vapor within a substantially enclosed chamber, and passing the non-absorbed portion of the flue gases through said chamber at a relatively low velocity. There is also disclosed an apparatus adapted to carry out the method of the present invention.

Abstract: A tubular structural member is inserted in a ground or soil formation by drilling the formation ahead of a cutting edge on the member proper and bringing the member to perform a combined rotary and axial movement so that the cutting edge is driven into the drilled zone. An apparatus for practicing the method comprises a drilling machine having a feed device, a cutting edge at one end of the structural member and a means for rotating and axially displacing the member.
