  • Digital frequency deviation meter
    Patent number: 4236110
    Abstract: A digital frequency deviation meter for measuring the deviation of an FM signal from a center frequency is disclosed. An incoming FM signal is applied to a counter which is cycled through a series of sequential nonambiguous cyclical states. A storage memory, actuated at a center frequency produced by a timer, is provided for storing information about the present and immediately preceding sampled states of the counter. Operating synchronously with the timer is a detector that responds to the differences in magnitude and direction between the present and immediately preceding sampled states of the counter and generates a pulse when a state difference is detected. A frequency counter counts the pulses which are output at a rate proportional to the frequency deviation. To maintain the timer at center frequency a phase lock loop is provided.

  • Dosimeter for measuring gaseous contaminants
    Patent number: 4235097
    Abstract: A personal dosimeter for measuring the time-average concentration of a gaseous contaminant in the atmosphere in a manner substantially independent of atmospheric motion relative to the dosimeter is provided. The dosimeter comprises a detector substance capable of chemically or physically combining with the gaseous contaminant disposed tightly between two substantially flat members, at least one of which has a plurality of through-and-through channels. The members have corresponding, meshing shapes such that the channels provide the only communication between the atmosphere and the detector substance, allowing the gaseous contaminant to diffuse through the channels.

  • Double acting hub-to-shaft clamp connection
    Patent number: 4235573
    Abstract: To permit accurate centering by means of compression rings which are pressed against conical surfaces of a tubular element inserted in the hub, and a sleeve with conical surfaces placed on the shaft, the compression rings are formed with axial centering ring extensions which, at their inner and outer surfaces engaging the hub, and the shaft, respectively, are bowed or curved in cross-section to be, for example, at least approximately part-spherical. Sequential tightening of bolts to draw the compression rings together and the respective conical surfaces over each other thus will not result in misalignment of the compression rings, or tilted or slanted bindings thereof with respect to the hub, or shaft, respectively, but insure accurate positioning of the compression rings, with the centering extensions around the shaft and within the hub.

  • Method for distortion-free still picture reproduction with magnetic video tape
    Patent number: 4236185
    Abstract: A method for distortion-free still picture reproduction from magnetic video tape slant tracks wherein the tracks are recorded and scanned without any guard band therebetween by means of two video heads which rotate in a common plane with different azimuth angles. During still picture recording, two adjacent slant tracks are continuously or repetitively scanned by two rotating video hands which have different azimuth angles with one head displaced axially by one slant track width with respect to the other. During still mode reproduction, the two adjacent slant tracks are continuously scanned by mechanically deflecting the two rotating video heads by way of plungers following a ring.
