Abstract: Abstract of the Disclosure A method of producing layer-like clad metal materials is disclosed.  The layer-like clad metal material is produced by applying at least one organic substance selected from the group consisting of phenolic resin, amino resin, epoxy resin, polyamide resin, acrylic resin, polyester resin and vinyl acetate resin, on a surface of a metallic core material having at its surface substantially no oxide film to form a coating film having a thickness of 50 to 3,000 µm, placing said core material in a casting mold, pouring a molten metal having the same or different composi-tion around said core material into said mold by a bottom pouring process to form a clad metal ingot, subjecting said ingot to slab rolling or forging to form an intermediate product, and then subjecting said intermediate product to a hot working and, if necessary, a cold working.

Abstract: 47,288 TRACTION MOTOR CURRENT CONTROL APPARATUS     ABSTRACT OF THE DISCLOSURE         A direct current motor power controlling chopper apparatus is disclosed which determines the operational speed of one or more traction motors propelling a passenger vehicle along a track.  The speed of the motor is estab-lished by changing the ON and OFF conduction ratio or duty cycle relationship of a thyristor switch device to determine the field current and the armature voltage of that motor.          The present apparatus can provide a greater controlled range of motor speeds including a lower minimum OFF operation and a full ON capability.  In addition, the present apparatus provides greater reliability due to less thermal stress on the thyristor switch devices and fewer circuit elements required to provide an improved motor current control operation.

Abstract: ABSTRACT OF THE DISCLOSURE There is disclosed a fiber optic waveguide which is particularly suited for infrared radiation transmission at extended wavelengths.  The core of the waveguide is fabricated from heavy ionic compounds selected from metal halides in order to achieve such extended infrared transparency.  While it is impossible to prepare these materials into optical fibers using conventional fiber drawing techniques, the present invention teaches how such materials may be prepared into optical fibers using an extrusion process at elevated temperatures and high pressures.

Abstract: ABSTRACT OF THE DISCLOSURE           The invention relates to a synchro drive system which includes a synchro unit having stator windings and an energized rotor.  Data, indicative of the desired position of the synchro unit, is generated and applied to a comparator to com-pare the actual position of the synchro unit with the data.  A switching selectively interconnects the stator windings of the synchro unit.  The switch is controlled by comparator to effect interconnections that drive the rotor in a direction to reduce the difference between the actual position and the data.

Abstract: ABSTRACT OF THE DISCLOSURE      For use in an automatic electric battery charger, a charge controller which monitors the rate of rise of battery voltage, and terminates the charge when the rate of rise falls below a pre-determined value, typically 11 mV per cell in 45 minutes for a lead-acid battery.  The battery voltage is monitored by combining with it a ramp signal which changes, in the opposite sense to the rise in battery voltage, at a rate just sufficient to offset a rise in battery voltage of the said predetermined value.  In the preferred embodiment, the combining step is performed by a summing amplifier, and a bias signal is also fed to the summing amplifier; this bias signal is shifted, in one direction only, to hold the output of the amplifier between narrow limits as long as the rate of rise of battery voltage is greater than the predetermined value. As soon as the rate of rise of battery voltage is no longer sufficient to offset the ramp signal, the amplifier output shifts outside the said limits, and this shift is used to terminate the charge.

Abstract: ABSTRACT OF THE DISCLOSURE A tube fitting assembly is disclosed wherein a ductile metal tube is forced into first and second orifices within a fitting   The tube is closely received within the first orifice and the second orifice is larger so that the axial force on the tube axially contracts the tube to form a radially expanded bead on the tube substantially filling the second orifice   This establishes a fluid tight seal between the tube and the fitting and also retains the tube in the fitting.  An annular deformable seal member is also provided between an outer surface of the tube and an inner surface of the fitting and this seal may be a rubber-like O-ring or a composition material which is more yieldably than the material of the tube and fitting, may be set up from a liquid or plastic sealant material, or may be a deformable wall of the fitting   The force used to axially contract and radially expand portions of the tube is also utilized to compress the deformable seal between an outer surface of the tube and an inner surface of the fitting to make doubly sure of good fluid-tight seal.  The tube fitting assembly is thus able to withstand higher pressures, suddenly applied pressures, corrosive fluids, and extreme and rapid changes in temperature, with only a negligible number of failures of the assemblies.
