    Abstract: A cylindrical body having a curved nose at one end and a flat base at the other end is connected to a disc of smaller diameter, with the disc being centered coincident with the longitudinal axis of the body and being spaced axially from the base thereof. This assembly, when aligned axially at midstream of a flowing fluid with the nose pointed upstream, generates a downstream wake in which the fluid traces an unsteady, irregular flow pattern, oscillatory in nature but with random, unpredictable variations and extinctions in the amplitude and frequency thereof. Modification of the assembly by an additional element of structure which splits or obstructs the fluid flow at or downstream from the space between the base and disc stabilizes the wake flow pattern into a fixed plane of strong oscillations the amplitude and frequency of which are readily measured. The frequency of the stabilized oscillations varies directly with the volumetric velocity of the fluid flow over a considerable range of velocities, whereby the modified assembly constitutes a simpler, linear, no-moving parts, digital-output flowmeter by which the fluid flow velocity can be readily measured with high precision.

    Abstract: The concentration of particles suspended in a fluid, having a refractive index which differs from that of the fluid, is accomplished using polarized light. The degree of depolarization of the incident light indicates the concentration of the particles in the fluid. While maintaining a constant observation angle, the distance between the light source unit and the detector unit is varied thus changing the focal point of the system. In this manner, suspended particle concentrations at varying distances from the light source and detector unit are obtained.

    Abstract: This invention comprises china or ceramic sanitary ware such as toilets, lavatories, bidets, and urinals, and similar articles which are made from materials having at least two contrasting colors and may be provided with an appearance resembling natural stone or marble. The invention also includes the process and apparatus for making such articles. Two or more ceramic wareforming slips of different colors are combined into a unitary stream but not completely blended when poured into the cavity of a moisture-absorbing mold. Special pouring and filling techniques are employed to facilitate the approximate repetition of a design in the formed article for those who desire to be able to repeat a particular design. Where desired, pouring and blending may also be controlled so as to avoid initial contact between the unitary slip stream and the visible or marketing surface of the mold forming the finished product where a product of a particular appearance is desired. This results in a natural stone or marblelike appearance of the finished product, and the particular design can be generally repeated in subsequent articles. Pouring may also be controlled so as to contact the marketing surface where such marbilized appearance is desired. For those who desire variation from product to product, this can be accomplished by varying color and slip compositions and by mold manipulation.

    Abstract: A folding partition consisting of a pair of acoustical assemblies or sides which combine the acoustical properties of sound absorption and sound transmission loss, and include a flexible blanket of sound absorbent fiberglass sandwiched between an inner vinyl lining and an outer fabric and a plurality of metal panels are attached to the inner side of the vinyl lining. The outer fabric is provided with a multiplicity of perforations for admitting sound into the fiberglass blanket where it is absorbed, while the metal panels further reduce the sound which passes through the fiberglass and further prevent it from passing through the closure.

    Abstract: Method for detecting optically active organic particles suspended in a fluid, including water, air or a vacuum, by measuring circular dichroic absorption. The method comprising the steps of alternately transmitting right circularly polarized light and left circularly polarized light through the fluid being analyzed whereby the circularly polarized light is scattered by the particulate matter in the sample. The scattered radiation is analyzed by separating the circularly polarized components in the resulting scattered light and measuring the intensity of the resulting scattered light components. The circular dichroic absorption in the scattered lights is represented by the ratio of the component intensity of when starting with right circularly polarized light to that of the intensity when starting with left circularly polarized light.

    Abstract: An adjustable shower head for the distribution of liquids having a control for regulating the flow of the spray. The shower head is constructed so that the forward pressure of the liquid on the shower head nozzle does not cause relative movement of the shower head parts. A piston-type of arrangement is employed wherein no fluid pressure is developed which acts on the adjusting mechanism.
