Abstract: A clamp with two segments and a process for applying a first clamp segment to a pair of flanges for adjacent fluid flow elements so that the first clamp segment is retained by the pair of flanges after application. Steps including 1) aligning a first flange with a second flange to form the pair of flanges; and 2) elastically deforming the first clamp segment to capture into the first clamp segment an arc of more than 180 degrees of the pair of flanges with the arc being sufficiently more than 180 degrees that after capture of the pair of flanges that the first clamp segment cannot be disengaged from the pair of flanges without application of sufficient force to elastically deform the first clamp segment to expand sufficiently to allow removal of the pair of flanges. Otherwise the first clamp segment is retained.

Abstract: An expandable slide and lock stent comprises a tubular member that can be expanded from a collapsed state to an expanded state. The tubular member can comprise a reversing helical backbone and at least one rail member extending from the helical backbone in a circumferential direction. The backbone can have at least one engagement element that can be configured to receive a rail member to form the tubular member. In some embodiments, the reversing helical backbone can comprise a plurality of discrete segments having a variable profile and/or wave form.

Abstract: A process for the treatment of water or other liquid has a plurality of stationary surfaces on which microorganisms or like biologically active materials are fixed or grown which are contacted alternately with air and the liquid undergoing treatment by raising and lowering the liquid. This leads to purification by biological oxidation and other processes. Apparatus for performing the process comprises a tank containing arrays of plates and a wave generator for generating a wave action of liquid in the tank by means of which the alternate raising and lowering of the liquid is achieved. Beneficially the wavelength of the wave motion is arranged such that the tank length is 1/2, 1 or n times the wavelength where 2.times.n is an integer.

Abstract: Apparatus and a method for aligning the rolling plane of each of the wheels of a car, truck, trailer or other wheeled vehicle to factory specifications and to be parallel to the thrust line of the rearmost wheels. The apparatus comprises various embodiments of an adjustable stationary reference "halo", mountable in concentric relation about a vehicle or trailer, and relative to which individual gauge assemblies mounted to each of the wheels detects each wheel's toe condition and permits the determination of the vehicle or trailer thrust line and the correction of the rear suspension thereto. Wheel mountable caster, camber and king-pin inclination/strut angle detecting assemblies, in turn, permit the detection of each of these respective conditions for each wheel and the correction of each condition in relation to the established thrust line.

Abstract: A method and apparatus for the preparation of thermosetting foam products on a substantially continuous basis, and wherein the products are characterized by uniformity of formulation, dimensional accuracy, and dimensional stability. The invention contemplates the utilization of an extruder which receives raw, partially or fully expanded resin and fillers or additives at inlets thereof, with initial expansion occurring within the confines of the extruder. The initially expanded resin is passed through a first expansion chamber with an intermediate expansion zone therein, with the outlet from the first expansion chamber being modestly constricted. From the first expansion chamber, the partially or fully expanded resinous product is moved through a second expansion chamber wherein the intermediate zone is enlarged, so as to permit substantially full expansion of the resinous material therewithin.

Abstract: Hydrophilic floral display foam blocks are prepared from frothed urea-formaldehyde, and wherein the urea-formaldehyde contains an alkyl-aryl sulfonate, and wherein the alkyl-aryl sulfonate has been exposed to an aqueous solution of a quaternary ammonium salt in an amount sufficient to provide at least equal molar concentrations of the quaternary ammonium salt to the alkyl-aryl sulfonate present in the foam. The urea-formaldehyde foam may also contain quantities of sodium molybdate to enhance the stability and lifetime of cut flowers retained in the foam material. Also, the urea-formaldehyde foam may contain starch to help suppress the free formaldehyde odor and help increase the biodegradability of the cured foam. The resulting foam is hydrophilic in nature, and hence is readily wetted, with the hydrophilic characteristic not adversely affecting the life of cut flowers retained therein.
