  • Total security time-delay circuit
    Patent number: 4559460
    Abstract: A total security time-delay circuit useful in railway communications, for example, provides a series of output pulses after a specific minimum interval in response to a direct voltage applied to an input of the circuit, the minimum interval being maintained even in the event of circuit component malfunctions. A pulse generator connected to the circuit input provides a series of pulses to control a first contact breaker which switches the primary winding of a transformer to partially discharge a capacitor which is series-connected to the primary winding. The capacitor charges through a resistive network of a transformer secondary winding circuit which includes a second contact breaker having a control terminal connected to the transformer secondary winding and operable to provide output pulses when the capacitor discharge reaches a sufficient intensity.

  • Method and apparatus for determination of the state of an all-or-none modulated alternating signal in a perturbed environment
    Patent number: 4555791
    Abstract: The state of an all-or-none modulated useful signal subjected to a perturbed environment is determined, on reception, through the use of non-modulated reference signals subjected to the same environment. The reference signals have respective frequencies neighboring that of the useful signal and the same initial amplitude so that all of the signals are attenuated in the same manner by environmental perturbations. By comparing against a threshold reference value the differences between the respective amplitudes of the received reference signals and the amplitude of the received useful signal, the "all" and "none" states of the useful signal are accurately determined irrespective of the effect of perturbed environment on the amplitude of the useful signal.

  • Control apparatus for back-driving computer memory and forcing execution of idle loop program in external memory
    Patent number: 4554630
    Abstract: This apparatus controls the execution and content of computer programs in equipment containing a computer by causing the transfer of program data elements, including computer instructions, with a memory of the apparatus. The selection of data for transfer is effected either by the computer, operating in a normal manner, or by the apparatus, which may shift data selection between these two selection options so that the computer ceases selection of data constituting one program and begins selecting data of another program. While data elements are being transferred with the computer, other elements of the memory are available for examination and modification such that new programs, the content of which may depend on the results of prior program execution, can be loaded, executed, and examined without interrupting, delaying, halting, or otherwise disturbing the instruction flow of the computer equipment.

  • Machine to apply a screwing or unscrewing torque
    Patent number: 4545269
    Abstract: A machine to apply screwing and unscrewing torque to successive drilling shafts employs upper and lower claws, one of which is fixed and the other of which rotates through a limited angular range. Each claw comprises a pair of right-angle branches extending oppositely from a base and terminating in spaced relation to provide a permanent opening at one side of the claw opposite to the base. Each claw has a jaw comprising three gripping elements positioned essentially at the vertices of an equilateral triangle, one gripping element being fixed to the base and the other gripping elements being movably mounted on the branches at opposite sides of the opening. One claw comprises a pair of parts relatively movable vertically to form a viewing opening when the machine is not applying torque.

  • Electron beam irradiating process for rendering rough or topographically irregular surface substrates smooth; and coated substrates produced thereby
    Patent number: 4537811
    Abstract: This disclosure involves a novel process for instantaneous electron-beam curing of very thin low viscosity, solventless coatings upon rough, irregular or textured surfaces of a substrate, such as paper or the like, that, through rather critical timing and energy adjustment procedures, causes the coating firmly to adhere to the surface before the coating can conform to the roughness or texture contour, and thereby providing a solidified very smooth outer surface for the substrate that is particularly useful for metalization and other finished layerings.

  • Method and means for installing a cable within a conduit
    Patent number: 4529172
    Abstract: This method is intended to permit installing of a cable of considerable length within a conduit, by means of a hauling line, under the most favorable possible conditions, so as to eliminate friction between the cable and the inner surface of the conduit, and, specifically, with reduction of tractive force to be applied to the cable. In accordance with the present invention, the aforementioned method consists of attaching the cable to a hauling line, according to its full length, at locations whose positions are to be determined in relation to resistance to tension affecting sections of the cable demarcated in this manner, so that, with the cable possessing some slackness, none of the sections of said cable shall be affected by stress affecting the preceding section, and so that tractive force shall be distributed along successive sections of the cable while it is being installed.
