Title: Railway track elastic mounting - uses second intermediate component which is of different elasticity from first component
IPC: E01B9/62
Filed: 1985-12-16
Abstract: The elastic mounting system is for a railway track on a support. An intermediate elastic component is inserted between the support and the base so as to give an antivibration effect and resist subsidence under a set load. - A second elastic component of a different degree of elasticity is for antivibration effect under a second set load. When the rail is under the first load, all the intermediate components are brought into use, while when under the second only the second one is in use.

Abstract: HIGH SURFACE AREA VALVE METAL POWDER                  Abstract of the Disclosure Solid particles of potassium fluotantalate are tho-roughly dried and then coated with molten form sodium reducing agent, the coating being accomplished under temperature condi-tions controlled to remain below a temperature which will ini-tiate the exothermic reduction reaction between these materials.          After completion of the coating, the charge of premixed double salt and reducing agent is then heated through the temperature at which the exothermic reduction reaction is initiated.  The initiation of the exothermic reaction causes a rapid tempera-ture rise.  Over 90% of the tantalum values of the salt charge are formed as elemental tantalum in particle form in the course of the exothermically driven temperature rise.  The charge temperature is then stabilized in the range of 700°-1100°C, held for a time at this elevated temperature and then slowly cooled.  During the temperature rise, tantalum metal particles nucleate throughout the mass of the premixed charge to form a coherent skeletal structure.  This skeleton resists settling as the temperature is raised above the melting temperature of the salt mass, and a substantially homogeneous distribution of tantalum values throughout the reduction charge is formed and maintained.  Tantalum metal particles, so formed are highly structured and can be separated as a high yield of high sur-face area - high capacitance tantalum powder.

Abstract: METHOD AND APPARATUS FOR CONTROLLING THE      RISETIME OF A DIGITAL MAGNETIC RECORDING WAVEFORM                            ABSTRACT Discrete magnetization areas on a magnetizable medium are switched by a magnetic field formed by current pulses through a magnetic head winding having relatively slow leading edge risetimes.  The current rise-time may be derived from conventional voltage pulses by alternately gating positive and negative timing circuits which control current flow.  Passive circuit elements may also control the leading and trailing edge timing.

Abstract: WINDSHIELD WIPER CONTROL CIRCUIT Abstract of the Disclosure: A windshield wiper control circuit which provides continuous and pulse wiping modes and which includes a wash unit override through which the washer unit may be energized while the wiper is operating in either mode.  The drive motor energizing circuit is completed through the contacts of an electrical relay, the operating coil of which may be grounded through three separate circuits including, respectively, the contacts of a selector switch and a manual wash cycle switch in parallel, a transistor Darlington pair, and two normally closed contacts which are operated by the drive motor to the electrical circuit open condition when the wiper is in the inner wipe or "home" position.  When the selector switch is operated to the Run position, the relay operating coil and drive motor are continuously energized to operate the wiper in the continuous mode and when operated to the Pulse posi-tion, the selector switch ground is removed from the relay operating coil and ground therefor is provided through the transistor Darlington pair which are triggered conductive at spaced intervals by a pulse control timing circuit coupled thereto to operate the wiper in the pulse mode.  When the manual wash cycle switch is operated to the Wash position while the wipers are off or in either operating mode, the washer unit is immediately activated to deliver wash fluid to the windshield during a wash cycle.  In addition, the wiper motor is immedi-ately reactivated to an operating condition.  At the conclusion of the wash fluid delivery cycle, additional drying wipes are provided and then the unit automatically returns to its pre-vious operating mode.

Abstract: ACTIVE HYBRID SIDETONE PRODUCING CIRCUITRY        FOR SIDETONELESS TELEPHONE            Abstract of the Disclosure A line circuit for a four-wire sidetoneless telephone is disclosed for use in a time division multiplex (TDM) communication system.  The line circuit comprises circuitry for interfacing two-wire transmit and two-wire receive paths with transmit and receive operational amplifiers of a TDM active hybrid.  Time division switches connect the amplifiers to respective transmit and receive TDM buses in time slots occurring in repetitive cycles and for exchanging communication signals on the buses.  A sample/hold capacitor is arranged for storing a sample of a communication signal obtained from the receive bus via a time division switch.  A resistor network couples an output signal from the transmit amplifier to an inverting input of the receive amplifier for cancelling a predetermined portion of the sampled signal applied to a noninverting input of the same amplifier from the sample/hold capacitor and for thereby providing a sidetone signal to the two-wire receive path.

Adams CAMBERING ATTACHMENT FOR TRUSS ASSEMBLY               JIG USING CANTED ROLLER PRESS                 Abstract of the Disclosure Joist trusses, having generally parallel upper and lower chord members, are necessarily manufactured with a camber and pre-ferably upon an assembly jig having a longitudinally disposed, mov-able, endless belt-like support surface for supporting precut wooden members arranged into the shape of a joist truss.  Clamping devices, mounted upon the support surface, hold the precut members in place and spiked, metal gusset plates are placed at opposite sides of each joint of the truss.  Two pairs of opposing, transversely-disposed rolls, arranged as roller presses, are locat-ed at one end of the  support surface, with a first pair of rolls being positioned to receive both the support surface and the assem-bled truss thereon, so as to partially impale the gusset plate spikes into the members.  The second pair of rolls are positioned beyond the support surface to tightly press the gusset plates against the sides of the truss as it passes through these rollers.          The second pair of rolls are skewed, or angled from a normal trans-verse axial position to impart a predetermined camber into a truss as it moves through these rolls.     :
