Abstract: ABSTRACT OF DISCLOSURE         A method and apparatus for monitoring the degradation of oil, particularly crankcase oil.  A first sensor includes creep material positioned under constant stress in thermal contact with the oil to act as an analogue computer as it changes its length in response to temperature and the time at that temperature to register the degradation of oil due to the oil's oxidation.  In addition, a second sensor registers the contam-ination of the oil by adding the number of time the oil is heated but not heated to a high enough predetermined temperature to disperse the water, acids and sludge which contaminate the oil.  When the combination of these outputs reach a predetermined limit, a signal is provided,  This is accomplished by an ap-paratus including a generally U-shaped bracket with a platform movably supported on the bracket for upward movement against a spring.  A rod extends through the platform and is connected to a diaphragm which, in turn, is subjected to oil pressure to move downwardly thereby moving the rod downwardly.  A creep material is supported on the platform and extends upwardly in the direction of the rod to a distal end and is placed under a constant stress by a spring reacting between the distal end and the platform.  The creep material changes in length exponentially when subjected to temperature and time, the operand of the exponent being the base of the natural system of logarithms.          Associated with the platform is a metal member having a pair of gripping tangs engaging the rod so that when the rod moves downwardly and returns after the oil pressure is released it will move the platform upwardly relative to the bracket unless the oil reaches a predetermined temperature at which time the tangs will move away from the rod allowing the rod to freely return upwardly without moving the platform.  When the combination of movement or elongation of the creep material and platform move-upwardly is sufficient that the distal end of the creep material contacts the upper portion of the bracket an electrical signal is provided indicating that the oil is sufficiently degraded to be replaced.

Abstract: ABSTRACT OF THE DISCLOSURE   Disclosed is a time division multiplex system in which frame syn-chronization requires a low transmitting capacity and a high synchronizing security on the one hand and a rapid reaction to synchronization interferences on the other hand.  According to this invention, two synchronized words, each comprising at least six synchronizing bits, are decoded and one synchronized bit each per frame is transmitted in the multiplex signal.  Upon recognition of the two synchronized words, a counter is reset in the unsynchronized state, by which counter a synchronizing signal is produced for controlling an address pick-up.  The synchronizing is monitored by means of one synchronizing word.

Abstract: HIGHWAY CROSSING SYSTEM WITH IMPROVED     MOTION DETECTING APPARATUS                 Abstract of the Disclosure A highway crossing warning system includes a motion detector transmitter and receiver respectively coupled to the track rails adjacent the highway crossing for detect-ing motion of an approaching train.  Wrap-around approach sections initiate operation of the highway crossing warning, but once motion is detected, the motion detector can serve to inhibit the highway crossing warning, after a predeter-mined delay, if motion indication ceases.  To increase the effectiveness of the motion detector, the motion detector transmitter impresses a modulated carrier onto the track rails, wherein the modulation is phase locked to the carrier.          The receiver, tuned to the carrier frequency, detects the modulation, and then determines from the level of demodu-lated signal whether or not approaching motion is detected.          The transmitter employs solid state circuits switched between saturated and off conditions to prevent circuit component failures from masking approach motion.  The ring sustain time period is arranged to provide a minimum con-stant warning time regardless of changes in train velocity, so long as train velocity is maintained above a predeter-mined threshold within a predetermined distance from the crossing.

Abstract: ABSTRACT OF THE DISCLOSURE           A method and means for providing a remote data station with access to the program memory of a stored program common control telecommunications switching system.  The control complex has an input/output port and a modem for interfacing that port with its switching network.  The control has the capability of setting up connections in the network between the modem and a selected trunk.  Incoming connections to the modem are given only limited access to the stored program control, that access for the purpose of analyzing incoming data to detect a predetermined code.  In the event the predetermined code is detected, the incoming connection is taken down, and an outgoing connection established to a distant station by dialing the number of an authorized station which is stored in the program memory.  Full access to the program memory is then allowed, such that full access is provided only to stations whose telephone numbers are stored in the memory of the switching exchange.
