Title: Water treatment system
Inventor: WHITE HAROLD R
IPC: C02F1/52
Filed: 1988-11-28
Granted: 1994-06-28
Abstract: ABSTRACT OF THE DISCLOSURE A method and apparatus for the removal or reduction of inorganic contaminants, hardness, radionuclides, organic contaminants, odor, turbidity, discoloration, and objectionable taste from water, subjects the water to lime-phosphate softening, aeration, sedimentation, filtration and ion exchange in an automatic cycle especially suited for home and small commercial usage.  The raw water, such as well water, is first subjected to a cold lime softening and aeration treatment, then to a phosphate treatment followed by settling and filtering.  The thus treated water is supplied to a pressurized tank feeding a conventional ion exchange water softening unit as the water is tapped for use.  No heat input is needed but the treated water can be heated as desired for use.  An electrical control system regulates the water and chemicals input, agitation, aeration, the time of chemical treatment in successive stages and the maintenance of a desired head pressure for the treated water.  The apparatus is compact, fully automatic in operation, low in cost and is well suited for use in private homes.

Abstract: Abstract Of The Disclosure An optical fiber coupler is formed by providing a glass tube having a longitudinal aperture.  Two contiguous carbon tubes are disposed within the longitudinal aperture which is thereafter collapsed thereon.  A glass capillary tube is formed by removing the carbon tubes.  The tube can be stretched, overcoated with additional glass, and again stretched to form a precision capillary tube which is severed into coupler-length tubes.  Two optical fibers, which are shorter in length than the aperture of a coupler-length tube, are centered in that aperture.  The midregion of the resultant assembly is heated and collapsed about central portions of the fibers.  The central region of the resultant coupler preform is heated and drawn to reduce the diameter thereof.  The end regions of the aperture, which are not diminished in size by the aforementioned processing, function as receptacles into which optical fibers can be inserted to make connection to the coupler.

Date Jun. 9, 1983.A self-retaining post of a plastic material, such as PVC, for use as a roadside marking post, a traffic sign post, a lamp post, or for other comparable uses in road traffic environments, has a channel-shaped bending zone with substantially arcuate cross-section and with the convex side facing the on-coming traffic. The cross-sectional area of the bending zone increases progressively towards the lower end, whereby the flaring-out zone formed upon bending of the post will be larger below than above the line of bending. The greater inherent resiliency of the material below than above the line of bending will cause the post to bend back into an upright position after having been hit by a vehicle. Certain embodiments of the posts are manufactured by diagonally splitting lengths of extrusion-molded plastic tubing, forming two identically shaped posts from each tube length.

Abstract: A process of manufacturing a roll of continuous synthetic thermoplastic film consisting of extruded flat film or of extruded blow-formed and flattened tubular film in which the thickness of the film is measured over the width of the film. Any striplike portion which deviates in thickness from a means thickness of the film is adjusted. The temperatures of juxtaposed temperature control sectors or the width of those portions of the slot die or of the annular die from which said striplike portions have been extruded are adjustable. When a striplike longitudinal portion having a relatively large thickness is detected in the film, the film is subsequently extruded to have a corresponding portion which has a relatively small thickness within specified thickness limits and for a length such that the two portions as superimposed in the roll have an average thickness approximately equal to the mean film thickness.

Abstract: Methods and compositions are provided for preparing stabilized interferons and for combining stabilized interferon with cigarettes. Special domains of the interferon molecule are recognized by methods which are described. A means for constructing these domains by recombinant DNA technology is detailed. A method for stabilizing natural interferons is also described. A process for combining the stabilized interferon with cigarettes is presented. The combination of interferons and cigarettes is synergistic, especially because interferon effects are magnified at elevated temperatures and because interferon has a preferential effect on tumor cells, but for other reasons as well. The process is not obvious and will be beneficial to a large segment of mankind; those who use tobacco products.

Abstract: An overload protection mechanism for a plough beam (3). The plough beam (3) carrying a plough body (6) is retained in ploughing position by means of a flexible, power-exerting device comprising a fluid pressure operated piston cylinder (11, 11', 12, 12'), the piston rod (12) thereof being coupled to the front end of a strut (10) anchored (9) at the rear end of the plough beam (3). However, plough beam (3) carrying plough body (6) may leave the ploughing position when the plough body (6) hits an obstacle (8) positioned in the soil and capable of being passed by the plough body (6) through a rotation of the plough beam (3) at the front end thereof, cooperating with the plough beam carrier (4) through a hinge device (16, 16'), the plough beam (3) thereafter being brought to retake the position corresponding to the ploughing position of the plough body (6). In order to achieve a protected positioning of the piston cylinder (11, 11', 12, 12') and, simultaneously, secure that the strut (10) at all times will be subjected to a tensile strain as plain as possible and minimum bending load, the piston cylinder (11, 11', 12, 12') is mounted in the plough beam carrier (4) by means of a universal joint (13, 14, 15).
