A material and method for producing mesostructured materials with multiple functionalities that are independently adjustable and collectively optimizable is provided. The method uses a series of discrete synthesis steps under otherwise mutually incompatible conditions, e.g., from acidic, alkaline, and/or non-aqueous solutions, allows different functionalities to be introduced to the materials and optimized. To illustrate the method, cubic mesoporous silica films were prepared from strongly acidic solutions that were separately functionalized under highly alkaline conditions to incorporate hydrophilic aluminosilica moieties and under non-aqueous conditions to introduce perfluorosulfonic-acid surface groups.

Molecular optimization of multiply-functionalized mesostructured materials

An adapter for coupling a pair of pipe elements through an opening formed in a wall includes a flange mounted thereon. The flange is pivotable relative to the adapter, whereby the flange automatically compensates a non-uniform thickness of the opening.

An auxiliary energy source is connected to the manually operated lift head of a vacuum lift system for connection of an accessory. Thus, electrical or compressed air energy is made conveniently available to power a load rotating accessory, a clamp, or the like, preferably by means of feeding a conduit line coaxially within the flexible tubing of the lift system. This is particularly useful to prevent interference or disarray of an auxiliary line that must be manipulated in tandem with the lift head, and is operable with rotary type lift systems that permit 360 degree rotation of the lift head.

This invention provides improved body length adjustment value structure for a vacuum powered lifting system of the type that embodies a variable length lifting body responsive to the differential of pressure inside that body with atmospheric pressure to resolve critical manual control problems. Thus control is provided by proportional movement of a control member over a substantially linear range producing a smooth progressive movement of the lifting mechanism. This permits non-critical lowering and release of a work load object by unskilled operators. Thus, an air injection valve with an air release port, is positioned within the lifting body having an elongated slot operable over a control range proportionately change the body length by release of a progressively increasing flow of air into the body to increase air pressure and body length over the critical range of lowering and releasing the work load object in response to a corresponding substantially linear movement of the control member. Variable adjustment value structure establishes a known upper lift limit by control of the length of the body both under loaded and unloaded conditions, and provisions are made to keep a vacuum responsive work object grasping mechanism continuously operable.

A hydrotherapy fitting assembly is provided, featuring: an axial nozzle socket and a nozzle therein, receiving an axial flow of water and air, and projecting them in admixture from the housing as a jet stream; the nozzle comprising two pieces threadably and fixedly linked together for pivoting and rotating movement together in the socket; a cylindrical housing piece defining a central chamber; a cylindrical plug valve piece having an axial water inlet at one end an axial water outlet at the other end, threadably mounted in the control chamber, and movable axially on the threads in the central chamber of the cylindrical housing between limiting positions extending across and closing off the side water inlets, and fully exposing and opening the side water inlets, with intermediate positions partially exposing and opening the side water inlets; and leaving the air inlet exposed and open in both limiting positions of the valve; and constraining water flow therethrough first in an axial direction, then in a direction at an angle thereto, and then again an axial direction, and thereby in an S-curved path; the cylindrical plug valve piece having a nozzle portion defining the axial water jet outlet of the plug valve piece and projecting mixed air and water from the nozzle mixing chamber.
