Abstract: ABSTRACT OF THE DISCLOSURE     A process for concentrating dilute phosphoric acid, in which dilute phosphoric acid is heated by an indirect heat exchange to a temperature below its boiling point and is subsequently sprayed and directly contacted with hot gases, whereafter water vapor and fluorine compounds are withdrawn with the exhaust gas and the fluorine compounds are removed from the exhaust gas.  The process is characterized in that the dilute phosphoric acid is heated by an indirect heat exchange with heat to be extracted from the absorption system of a sulfuric acid contact process plant, the heated dilute phosphoric acid is sprayed into and phosphoric acid is circu-lated through two successive concentrating stages and in said stages is sprayed and directly contacted with a heated gas mixture consisting of the tail gas of the sulfuric acid contact process plant and of admixed air, the gas mixture is heated by an indirect heat exchange with surplus gas heat of the gases which have left the first contacting stage of the sulfuric acid contact process plant and have partly been converted to SO3 and have not yet entered the high-temperature interstage absorption system, the heated gas mixture is conducted through the first and second concentrating-stages in succession and the exhaust gas is subjected to a plurality of scrubbing stages for removing the fluorine compounds by absorption.          The process of the invention avoids the use of primary energy or steam for producing the hot gases and also enables one to minimize the operating costs as well as the acid fume content of the exhaust gas.

Abstract: AN IMPROVEMENT IN ULTRASONOGRAPHY                   Abstract of the Disclosure A process is disclosed of forming a visible ultrasonographic image in a silver halide emulsion layer.          This is achieved by imagewise exposing the layer to ultra-sonic radiation at an intensity and for a duration sufficient to alter the exposure response of the emulsion layer to electromagnetic radiation, but below that which will produce a latent image in the absence of externally applied electro-magnetic radiation.  The layer is concurrently or sub-sequently exposed to electromagnetic radiation to produce a latent image therein defined by the imagewise ultrasonic radiation exposure.  The element is then photographically processed to produce a visible image in the emulsion layer corresponding to the latent image.

Abstract: OSCILLATING SPRAY DEVICE     ABSTRACT         A fluid dispersal device utilizes the Karman Vortex street phenomenon to cyclically oscillate a fluid stream before issuing the stream in a desired flow pattern.          A chamber includes an inlet and outlet with an obstacle or island disposed therebetween to establish the vortex street.  The vortex street causes the stream to be cyclically swept transversely of its flow direction in a manner largely determined by the size and shape of the obstacle relative to the inlet and outlet, the spacing between the obstacle and the outlet, the outlet area, and the Reynolds number of the stream.          Depending on these factors, the flow pattern of the stream issued from the outlet may be either:  a swept jet, residing wholly in the plane of the device and which breaks up into droplets solely as a result of the cyclic sweeping, the resulting spray pattern forming a line when impinging on a target; or a swept sheet, the sheet being normal to the plane of the device and being swept in the plane of the device, the resulting pattern containing smaller droplets than the swept jet pattern and covering a two-dimensional area when impinging upon a target.

Abstract: Abstract of the Disclosure This invention relates to a method for depositing  a metal in a selected pattern on a surface, which comprises treating the surface with a sensitizing solution comprising at least a reducible salt of a non-noble metal and a radiation-sensitive reducing agent for the salt to form a sensitized surface.  The sensitized surface is exposed to a source of light radiation to reduce the metal salt to a reduced metal salt species. Either or both of the preceding sensitizing or radiation exposing steps is restricted to a selected pattern on the surface to form a catalytic real image capable of directly catalyzing the deposition of a metal thereon from an  electroless metal deposition solution.  The improvement resides in treating the catalytic real image with a stabilizer solution comprising (a) a reducing agent for the non-noble metal ions of said reducible salt, (b) a complexing agent and (c) an accelerator to at least stabilize the catalytic real image.

Abstract: ABSTRACT OF THE DISCLOSURE        A method of producing an acidified meat emulsion product having a pH of 4.5 or below without shorting or breaking the emulsion during or subsequent to its formation.  The acidified product has improved microbial stability and may be thermally processed under conditions less severe than conventional meat emulsion products.  An edible acidulent is incorporated in an emulsified meat mix in an amount sufficient to reduce the pH of the emulsion to 4.5 or below.  The meat emulsion is stabilized to the acid stress, and shorting or breaking of the emulsion prevented, by incorporating an edible hydrocolloid in the meat emulsion.  Greater stability is provided by the addition of a slow release acidulent to the meat emulsion in conjunction with an edible hydrocolloid.  The acidified meat emulsion may be filled into cans and heat processed to provide a commercially sterile, shelf stable product or may be stuffed into casings and cooked to provide a refrigerator or freezer stable sausage or meat loaf product.

Movement of the carriage toward the socket moves the retaining member form a disenganged position in which it is spaced apart from a tool disposed in the socket to an engaged position in which the retaining member abuts the tool and presses it firmly into the socket. As the carriage moves toward the socket, the retaining member rotates relative to the carriage form the disengaged position in which it is disposed at an oblique angle to the central axis of he socket to the engaged position in which it is more closely parallel to the central aixs of the socket.  The pivotal movement of the retaining member enables a major component of the force holding the tool in the socket to be transmitted in a direction which is parallel to the central aixs of the tool to thereby maximized the component of force holding the tool in the socket.
