Abstract: ABSTRACT OF THE DISCLOSURE                An apparatus for monitoring the performance of a reverse osmosis water purification system.  The resistivity of the water, and hence its dissolved ionic material concen-tration, is measured at both the inlet and product ports of the system by resistance sensors forming two legs of a wheat-stone bridge.  The bridge is powered by two oppositely phased AC signals.  The output of the bridge drives a phase sensitive null detector which generates a null error signal.  After thresholding, the null error signal actuates a bidirectional meter to indicate the degree of bridge unbalance, as well as to actuate an alarm circuit if the outlet resistance falls below a predetermined value, thereby indicating an unaccept-able degree of purification.                The bridge is balanced by a potentiometer forming a pair of bridge legs on each side of the potentiometer wiper. Thus, when the bridge is balanced, the setting of the potenti-ometer wiper corresponds to a given ratio of inlet resistance to outlet resistance.  This ratio corresponds to the percentage of ionic material in the product water which has been rejected from the inlet water.  The potentiometer dial is calibrated in percent rejection, thereby giving an indication of the per-formance of the reverse osmosic water purification system.           Means are also provided for actuating an alarm when the percent rejection falls below a predetermined value and for reading directly the resistivity, and hence ion concentra-tion, of both inlet and product water.

Abstract: ACOUSTIC WAVE DEVICES INVOLVING PERTURBATION OF ACOUSTIC VELOCITY      BY DIFFUSION OF METALS            Abstract of the Disclosure Acoustic waveguides, acoustic filters and acoustic reflectors are based upon the discovery of increased acoustic wave velocity in materials such as lithium niobate and lithium tantalate into which a metal such as titanium, nickel or chromium has been diffused.          Velocity increases larger than 1 percent have been obtained; and negligible effect on acoustic loss is incurred thereby.  The technique and the resulting devices result in a simpler structure than provided by the metallic strips or the ion beam etched surface regions of prior acoustic devices in which velocity perturbations of comparable magnitude have been desired.

Abstract: Abstract of the Disclosure A process is disclosed for the rapid, continuous and waterless dyeing of textile and plastic materials in which the dyestuff is dissolved, suspended or dispersed in a high boiling solvent, such as glycol or glycol ether, for carrying out the dyeing step per se, after which the dyed textile or plastic ma-terial (after cooling if desired) is subjected to a washing with a low boiling organic liquid such as methanol or ethanol (prefer-ably the former) or a chlorinated hydrocarbon solvent, and sub-sequently dried.  The entire series of operations is carried out under nonaqueous or substantially nonaqueous conditions with the complete or substantially complete recovery and recycling of the used dyestuff, the used high boiling solvent, and the used low boiling organic wash liquid.  In this way the entire operation is conducted in a relatively inexpensive fashion and in a completely or substantially completely closed cyclic system with essentially complete recovery and reuse of the treating liquids so that not only is the cost of the overall operation greatly minimized but also without any need for pollution of natural water resources such as rivers and wells such as has in the past taken place to a more or less serious extent where effluents of a substantially aqueous nature, but containing serious amounts of polluting sub-stances, were discharged into rivers and the like thereby creating environmental problems.         In the case of textile materials such as woven or knitted fabrics, texturizing and heat-setting thereof may be effected simultaneously with the dyeing operation either to a relatively smaller extent due to the natural moisture pickup of the starting textile material, or to a relatively greater [and predetermined) extent by first incorporating in the textile material a still greater amount of a liquid texturizing agent (e.g., water or methanol) in an amount on the order of 10 to 60% by weight.         Finally, one may omit the dyestuff during the last-mentioned procedure and in that way bring about an excellent texturizing and heat-setting, only, of the textile material.

Abstract: A B S T R A C T             A woven fabric made from flat warp and weft tapes of polypropylene, such as is currently used as a primary carpet backing, is subjected to a repeated needling operation which breaks down each warp and weft component into a multiplicity of fibrils. This fibrillation of the warp and weft in the woven fabric produces a marked change in the surface of the fabric from a relatively shiny to a relatively matt finish. The fibrillated fabric may be rendered dyeable to a good coloration (similar to the colour of dyed face yarns of a carpet) either by including a dyeable material in with the polypropylene from which the tapes are originally formed, or by adhering a dyeable coating to the fibrillated fabric. Further repetition of the needling operation reduces the denier of the fibrils still more and produces a generally softer fabric.

Abstract: A SAILING SYSTEM                 Abstract of the Disclosure This invention is directed to a new form of a sailing system for overcoming some of the outstanding deficiencies in conventional sailing systems.  The teachings and practices of this invention lead to a large increase in the propulsive efficiency of sailing systems by reducing the turbulence on the leeward side of the mainsail and, also, allowing a smooth entry for the wind to the leeward side of the mainsail.  This is accomplished by rotating the mainmast and spreader with respect to each other and making it possible to rotate the mainmast with-in the spreader.  The spreader remains, substantially, stationary as it is supported by the boat rigging and not by the mast.          Further, this sailing system employs a soft sail.  The soft sail makes it possible to realize greater propulsive efficiency of the sailing system and the soft sail can move around the mast.

Abstract: ABSTRACT OF THE DISCLOSURE         A hemostatic clip applicator useful in the rapid and automatic application of hemostatic clips for the strangulation of tubular members is disclosed.  The applicator consists of a main body, a clip magazine externally attached to the main body, clip deforming jaws attached to one end of the main body, clip feed means located within the clip magazine, and actuating means attached to the feed means and deforming jaws.  In operation, one of many hemostatic clips stored in the clip magazine is fed into the deforming jaws by the interaction of the actuating means and the feed means.  When the clip is properly located about a tubular member, further actuation of the actuating means results in the deformation of the clip about the tubular member.  Upon further activation of the actuating means, the sequential process of feeding a clip from the magazine and deforming the clip about other tubular members may be rapidly repeated until the supply of clips in the magazine is depleted.
