  • Patent number: 4138676
    Abstract: A method and device for increasing security with respect to transmission faults in an information-transmission system, particularly for the railroad field, in which an interrogation device and a passive response device are movable relative to one another, and the interrogation device transmits an interrogation signal, which can be periodically swept through a predetermined frequency band, preferably in the microwave range, and which during a read operation, receives during several periods from the passive response device, a frequency-selectively reflected interrogation signal, in accordance with a k-digit information item to be transmitted, which signal forms the response signal, with the response signals being suitably identified and one of a series thereof, preferably that with the least errors therein, being suitably through-connected for subsequent utilization, in which not only is the response signal with the fewest errors utilized, but of the signals having the same minimum number of errors, that respon

  • Patent number: 4138610
    Abstract: In the illustrated embodiment, a series of detectors subject to additive errors in measurement due to high voltage variations is provided with a reference channel having a detector or an equivalent component which is not exposed to the radiation, but which is responsive to high voltage fluctuations. The output from the reference channel during each measurement cycle is supplied to multiplier circuitry which receives from each channel as a second input a stored constant representing the deviation in sensitivity of the channel detector as compared to the reference detector or equivalent. The output from the multiplier is combined with the measured value from such channel by means of a subtractor circuit so as to correct the output from the channel for the errors introduced by fluctuations in the high voltage supply.

  • Patent number: 4138679
    Abstract: A circuit is provided for synchronizing the oscillation U.sub.o of a pulsed oscillator with a reference oscillation U.sub.m of comparatively small amplitude. The reference oscillation is coupled into the oscillator and a phase control loop is provided in which a phase discriminator compares the phase relationship of both oscillations and provides a resulting control voltage for controlling an adjustable reactance for the frequency change of the pulsed oscillator during the leading edge of the pulse. A phase shifter, adjustable up to 180.degree., is connected between the oscillator and the phase discriminator. The output of the phase discriminator, which is highly resistive, is connected in a low-resistance manner to the adjustable reactance by way of an impedance converter, such as an emitter follower or a multi-stage wide-band amplifier.

  • Patent number: 4138331
    Abstract: A method of incinerating toilet waste comprising applying combustion heat in substantially the manner of applying heat to the bottom of a cooking pot under and to and through the bottom of a heat permeable upwardly opening receptacle containing the waste and thereby effecting substantial boiling and incineration of the waste, supplying preheated air into the receptacle, and compelling vapor and products of combustion generated by the combustion heat to pass from the receptacle into a combustion zone under the receptacle and through the combustion heat and into an after burner flue leading from the combustion chamber. An aesthetically desirable and sanitary masking foam may be applied to the surface of accumulated toilet waste in the receptacle prior to boiling and incineration.

  • Patent number: 4137736
    Abstract: An agitator for a vertical axis automatic clothes washing machine has an upper, auger portion which is rotatable in one direction about the vertical axis. A lower portion of the agitator oscillates in two directions. The lower portion has a skirt and carries radially-extending vanes on an upper surface thereof. A plurality of crescent-shaped, lobe-like lifting cams project outwardly and upwardly from a periphery of the skirt. Fabric articles contacted by the cam surfaces as the lower portion of the agitator oscillates to and fro during clothes washing are continuously lifted at the lower, outer portion of the wash basket and urged along a desired toroidal rollover path. The effective, high density washing action provided permits use of less hot water, rinse water, and detergent than in previously known agitation devices, and allows use of a small machine container for normal wash loads.

  • Patent number: 4137737
    Abstract: An agitator for a vertical-axis automatic clothes washing machine has a plurality of circumferentially spaced apart vanes extending upwardly from a skirt adapted to overlie the bottom wall of a tub or receptacle. A corresponding plurality of lobe-like cams projects outwardly and upwardly from at or near the periphery of the skirt in the alternate spaces between the vanes. Each cam extends approximately 5 to 15.degree. upwardly from the horizontal and is geometrically defined by two edges forming a segment of the surface of a cone co-axial with the agitator. The inner edge of each cam has the radius of the circular perimeter of the agitator skirt with which the edge is co-linear; the upper edge either has a somewhat smaller radius in a crescent-shaped configuration or has an irregular, double-lobe configuration.
