Abstract: ABSTRACT OF THE DISCLOSURE An elastic detergent bar of improved elevated temperature stability and method of making same, the improved stability permitting better shape retention on storage at temperatures somewhat higher than normal, includes an amphoteric synthetic organic detergent in mixture with an anionic synthetic organic detergent, gelatin, water and insoluble gas in very small bubble form distributed throughout the bar.  The bars are substantially form-retaining during storage and although they wear away during use, substantially retain their initial forms and elasticities for major proportions of their useful lives.  Compared to similar bars in which the insoluble gas, such as air, is not present, the invented bars are stable at higher storage temperatures, e g., 5 to 10°C. higher, making them commercially much more acceptable. Additionally, the elastic detergent bars are resistant to breakage during shipment and use, exhibit less surface tackiness than similar control bars, are very easily molded to finely figured and detailed shapes and of course, because of their lower density, float.

Abstract: MIXING VALVE ANTI-SCALD APPARATUS                      ABSTRACT OF THE DISCLOSURE    Anti-scald apparatus for inclusion on a water mixing valve of the type commonly used in showers.  The apparatus permits normal manual operation of the valve from an off position, through intermediate positions that allow mixtures of various proportions of hot and cold water to pass through the valve and toward the maximum temperature hot water position. However, the valve cannot be adjusted to reach this maximum temperature position without the performance of a positive, manual procedure by the valve operator, thereby reducing the possibility of accidental or inad-vertent scalding.  Stop means carried by the valve operating handle and easily accessible to the valve operator cooperate with a fixed stop on the valve to preclude valve adjustment beyond a predetermined high temper ature setting until the stop means manually are disengaged.  The stop means automatically will be repositioned in an operative position when the valve is adjusted to cooler water temperature settings than the setting at which the stop means and fixed stop become engaged.

Abstract: Abstract of the Disclosure A process is provided for the production of a coating composition con-taining microcapsules having a hydrophilic core for use in the manufacture of pressure-sensitive carbonless transfer papers comprising the following steps. A hydrophilic emulsion component is prepared by dispersing at least one chromo-genic material being soluble in the hydrophilic liquid.  A hydrophobic emulsion component is prepared by dispersing an emulsifier in a radiation curable hydro-phobic liquid.  A first wall-forming material and a second wall-forming materialare added to the hydrophobic emulsion component, with mixing.  The first and second wall-forming materials are soluble in the hydrophobic emulsion component,and the first wall-forming material is reactive with the second wall-forming material to form a polymeric capsule wall.  The resultant polymeric capsule wallis substantially insoluble in the hydrophilic and the hydrophobic emulsion com-ponents.  The hydrophobic emulsion component is mixed together with the hydro-philic emulsion component to form an emulsion containing droplets of the hydro-philic emulsion component dispersed in the hydrophobic emulsion component.  Mixing is maintained for a period of time sufficient to allow the first and second wall-forming materials to react to form a dispersion of microcapsules in the hydro-phobic emulsion component.  The formed microcapsules have capsule walls substan-tially impermeable to the hydrophobic and the hydrophilic emulsion components. Pressure-sensitive carbonless transfer paper may be produced by applying the dispersion of the microcapsules prepared as above to a substrate, and curingthe dispersion by subjecting the dispersion on the substrate to radiation for a period of time  sufficient to cure the radiation curable hydrophobic liquid, thereby producing a tack-free, resinous film on the substrate.

Abstract: ABSTRACT OF THE DISCLOSURE            In the illustrative embodiments of the invention disclosed, autostereoscopic pictures are produced by taking a series of two-dimensional views of an object field and pro- . jecting them in an enlarger onto lenticular print film. Adjustable-focus and fixed-focus cameras are provided for taking the two-dimensional views, either simultaneously or sequentially, in a manner which automatically accounts for the effect of variation of the camera-to-object distance on the configuration of the enlarger-lenticular print film system, thereby allowing the parameters of the enlarger-print film system to be held constant.  The number of enlarging lenses employed may correspond to the number of two-dimensional views to be projected, by virtue of which the stereoscopic picture may be composed in a single projection step, or a single en-larging lens may be used to project the two-dimensional views in sequence.  As another feature of the invention, substantially uninterrupted and non-overlapping lineiform image bands of high image quality are formed on all areas of the lenticular film by scanning the projected images from each two-dimensional view over a predetermined distance along the photosensitive surface.

Abstract: ABSTRACT     A method of manufacturing leaky coaxial cables having an array of apertures in the conductive outer layer. The total area of the apertures is a predetermined fraction of the surface area of the cable.  A pair of strip conductors of particular widths are selected and wound around the inner conductor and dielectric at predetermined pitch angles. This provides apertures having a total area which is a predetermined fraction of the surface area of the cable, a predetermined shape and being of a predetermined number per unit length.  By varying the pitch angle during winding the distribution of apertures and hence the coupling of the cable can be varied.  By testing short sections of cables of different geometry a coupling function and an attenuation function can be calculated to provide data for winding cables with desired characteristics.

Abstract: ABSTRACT The present invention relates to the connection of in-sulated electric wires, and it pertains more precisely to a terminal and a connection block for electrically connecting two insulated wires without prestripping them.  Prior art connecting devices that operate without prestripping are usually in the form of a flat spring, cut in a U shaped the branches of which define a slot.  In such devices, the insulated wire to be connected is introduced at the end of the slot adjacent the free ends of the branches.  This type of device has a disadvantage since the perforation of the insula-tion is made where the deformation of the branches is the easiest. The self-stripping connecting device of the present invention is constituted by a flat spring including a portion forming a U, the branches of which are elastically biased one against the other, and an opening to allow the introduction of the insulated wire at the end of the slot adjacent the base of the U.  Additionally a connecting block is disclosed which comprises an insulating box having at least one bore for receiving an insulated wire, and a movable element having a connecting device and being movable from a first position in which an inserting opening of the connect-ing device is in line with the bore, toward a second position in which the end of the slot remote from the opening is in line with the bore.
