Abstract: Abstract A rivet bucking tool (10) is provided with a damping piston (13) having a skirt (18) thereon in which the shank (25) of a rivet bucking die (23) is freely removably received. This allows easy exchange of the dies (23) for piston recoil adaptation to rivets of different size and material. The area transformation between the shank (25) and the damping piston (13), the skirt (18) thereon, and the preferably airtight frictional fit of the skirt (18) around the shank (25) are utilized   to convert bucking stress into vibration so as to reduce joint recoil of the damping piston (13) and die (23) during bucking. Vibration and recoil are absorbed in the tool housing (11) by compressed air in a damping chamber (42) wherein the pressure is selectively adjustable by a valve (28).

Abstract: Abstract of the Disclosure Public alert and advisory systems for the communication of emergency and/or other information from one or more central locations to a plurality of remote locations, such as, by way of example, information rgarding a nuclear accident and evacuation procedures.  This system utilizes conventional programming stations such as AM, FM or TV stations, central transmitting equipment, with the emergency information being modulated by a second modulation technique differing from the first modulation technique for the ordinary programming so that conventional manually operated programming receivers will not be responsive to the emergency information.  The receivers  of the system however, are responsive to the transmitted emergency information, so as to sound a warning alarm, display codes relating to evacuation or other information and/or receive and present audio information depending upon the specific configuration of the system.          Normally the remote receivers are given recognition codes so that the receiver may be given different emergency information, either on an individual or on a group to group basis.  Fault detection is provided by configuring the remote receivers to automatically provide a fault indication if not periodically reset by the communications link.  A unique telephone link, also disclosed, can be used for reliability testing or for ordinary data communication.  Various embodiments and features are disclosed.

Abstract: ABSTRACT OF THE DISCLOSURE         In a method and an instrument for testing materials on the Eddy current principle, at different frequencies depending on the output signal of a coil system, compensation values are generated which are typical of interfering factors.  These com-pensation values are subsequently superimposed on the output sig-nal in order to remove the influence of the interfering factors on the measurement.  In this manner with a favorable setting of the working point of an amplifier receiving the output values is obtained, an overmodulation avoided, and the dynamic range of the amplifier optimally utilized.  Therefore good measuring re-sults can be obtained even if the percentage of the interfering signals as compared to the detection signal controlling is rela-tively high.

Abstract: Abstract of the Disclosure Apparatus for transferring toner magnetically adhering to magnetic images stored in a magnet image-storage medium to a toner-adherable receiving medium such as paper.          Included is a platen which presses the paper against the storage medium to form regions of contact and noncontact between the paper and storage medium.  A boundary between the two regions is defined by a line of contact.  The apparatus also includes magnets for producing a magnetic field in the paper and storage medium which is asymetrical with respect to the line of contact.  The field is stronger in the region of noncontact than in the region of contact.  In the preferred embodiment, the field originates from a pair of spaced-apart, confronting magnetic poles disposed on a side of the paper opposite from the storage medium.  The apparatus is structured to produce selectively a field in the storage medium having a magnetizing force less than or, alternatively, greater than, the coercivity of the storage medium.

Abstract: C-8392 AN IMPROVED PROCESS FOR CALCIUM HYPOCHLORITE ABSTRACT OF THE DISCLOSURE A process for producing neutral calcium hypochlorite which comprises reacting an aqueous slurry of lime containing insoluble impurities with chlorine in a first crystallizer to form a first slurry of dibasic calcium hypochlorite crystals and insoluble impurities in a calcium chloride mother liquor. The insoluble impurities are separated from the first slurry of dibasic calcium hypochlorite crystals by employing separation means fox classifying solids with respect to particle size. Dibasic calcium hypochlorite crystals are then separated from the calcium chloride mother liquor and admixed with an alkali metal hypochlorite and recycle dibasic calcium hypochlorite crystals in a mixing zone to form a mixing zone slurry. The mixing zone slurry is reacted with chlorine to form a paste of neutral calcium hypochlorite. The paste is separated into a cake of neutral calcium hypo-chlorite and a paste liquor and the cake of neutral calcium hypochlorite recovered. The paste liquor is reacted with lime in a second crystallizer to form a second slurry of dibasic calcium hypochlorite crystals in a mother liquor. The dibasic calcium hypochlorite crystals are separated from dibasic mother liquor and returned to the mixing zone as recycle dibasic calcium hypochlorite. The novel process can employ low quality lime as it effectively removes insoluble impurities The process also efficiently recovers calcium and hypochlorite values from process streams.

Abstract: Abstract of the Disclosure A porous glass optical waveguide preform is formed by depositing a coating of glass particulate material on the lateral surface of a core which may be a porous glass body continuously produced by the axial deposition of glass particles.  The core rotates and moves longitudinally in one direction with respect to two flame hydrolysis burners which emit streams of glass particles having different compositions.          In addition, the two burners reciprocatingly move with respect to a portion of the length of the core.  The speed of each burner varies as it traverses along its path of reciprocating motion.  The thickness of the layer produced by a burner at a given point is inversely related to the speed of the burner as it passes that point. The layers formed by the completion of a single traverse by both burners combine to form a conically-shaped layer, the composition of which varies from the base toward the apex thereof.  The conically-shaped layer, which are adjacently located longitudinally along the preform, combine to form a cylindrically-shaped portion of the preform.
