Abstract: In typical hydrocarbon-contaminated ground water, the level of dissolved oxygen is low due to the high biological oxygen demand. The present invention increases dissolved oxygen levels in the ground water thereby increasing biological activity. The increased biological activity means that more of the dissolved hydrocarbons will be consumed at a greater rate. The instant process and apparatus for remediating dissolved hydrocarbon in ground water involves drawing ambient air down through a tubing and aeration stone into ground water by the vacuum created by a soil vapor extraction (SVE) system thereby increasing the amount of dissolved oxygen in the SVE well and in the ground water resulting in enhanced biodegradation by aerobic microbes.

Abstract: Apparatus and systems for transporting a generally cylindrical package include: (a) a frame including a support device having at least one compressible support member and a pivot device for pivoting the support device about a generally vertical axis, the support device being movable along the generally vertical axis between (1) a first predetermined position spaced apart from and below an outer surface of a generally cylindrical package which is removably telescoped upon a generally horizontal member of a support at a first predetermined location and (2) a second predetermined position in which the compressible support member contacts and supports at least a portion of the outer surface of the generally cylindrical package; and (b) a carriage assembly connected to and supporting the frame, the carriage assembly including a carriage for moving the frame between (1) a first predetermined position proximate the support and (2) a second predetermined position horizontally spaced apart from the first predetermined

Abstract: A dispenser for a container of pipe sealant and the like comprising a dispensing closure for preventing the lateral spread of a compound contained by the container as it is dispensed and having a bristle assembly which prevents removal of the compound after it has been deposited and spread between the threads of a pipe.

Abstract: The specification of the instant invention discloses improvements in methods for making various types of mats of fiberous material. In particular, the improvements relate to methods for making continuous fiber glass strand mats using reciprocating strand feeders and a programmable motion controller to control both the rate of reciprocation and the rate at which strand is deposited from the feeders onto a moving conveyor so as to form mats of uniform density and thickness. Electric servomotors are used to reciprocate the feeders and also deposit strand therefrom. A closed-loop feedback circuit is used to accurately monitor and control the position of the feeders with respect to the conveyor as well as the rate of strand deposition. Methods for using the programmable motion controller described herein can increase the uniformity of needled, resin-impregnated, and uni-directional fiber glass mats.

Abstract: A strand deflector used in the manufacture of continuous strands is shown and described. The deflector comprises a rigid surface which stretches across the width of the mat making machine and which is interposed between the strand feeders located above it and the mat making surface so that the strands fed toward the surface must deflect from the deflector surface before they are collected on the mat making surface. The deflector surface is adjustable in the vertical direction and the angle of deflection with respect to the flow of strand from the feeder may also be changed to any desired value.

Abstract: A fiber glass bushing is described which produces hollow glass fibers from a multiplicity of tips having air tubes centered inside of them. Modules for providing a common header for rows of tubes centered in rows of tips on the bushing bottom are shown along with means to maintain the tubes centered during the running of the bushing.

Abstract: A bushing tip suitable for producing hollow fibers is described which is formed from a centrally disposed gas tube preferably integral with the walls of the tip and constructed such that a gas passage is provided through the tip with at least one glass delivery channel is also provided through the tip and around the gas tube. Means are also provided to connect the gas tube to a suitable gas supply.

Abstract: A flat plate bushing is described which eliminates extensive precious metal use in drain and/or production bushings. The bushing utilizes a novel arrangement of insulation members and support plates that allow the bushing to be electrically heated and a novel method of connecting the bushing to a power source using the bushing face plate as the connection point is also shown.

Abstract: A method and apparatus for forming glass fibers is disclosed. The method of the present invention involves passing a narrow, high velocity air stream horizontally below the bushing to thereby induce and entrain additional air flow from the environment surrounding the bushing into this air stream to flow generally horizontally below the bushing. Suitable apparatus, such as an air amplifier, is employed to produce this desired result.

Abstract: An apparatus for producing glass fibers is disclosed. The apparatus includes means associated with an applicator for moving the glass filaments from the surface of the applicator when waste filaments are being produced such that the glass filaments are brought into contact with the application surface for coating the filaments with a binder and/or size only when production quality strand is being produced. This substantially reduces binder and/or size consumption and prevents the operator of the forming position from coming into physical contact with the binder and/or size coated strand.

Abstract: A method and apparatus for the chopping of glass strands is disclosed. The back-up or cot roller for the chopping blades includes an annular cutting surface or ring which is mounted on an expandable wheel, such as an inflatable wheel. By varying fluid pressure within the inflatable wheel, variations in the resiliency of the cutting surface are realized. This allows for a smoother operation of the chopping system and increases the life of the cutting surface. Further, the expandable wheel around which the cutting surface rides will adapt for variations in the thickness of the annular cutting surface and still give a consistent mesh with the cutting blades. Thus, it is now possible to employ cutting rings having inconsistent inner and outer diameters and to resurface the cutting surface by grinding that portion of the surface which has been partially gouged by the cutting blades to an even surface once again and thus to reuse the cutting ring.
