Abstract: ABSTRACT OF THE DISCLOSURE         The disclosure herein provides a circuit which can be connected to data lines coming into a multiplexer at a remote location where those data lines are multiplexed or information otherwise concentrated for transmittal to a central location; the circuitry has associated with it a unique telephone number which, when dialed by someone at the central facility, connects the data monitor to the central facility via the telephone lines; each of the data lines is associated with a unique coded number so that, when that number is entered into the interrogating telephone by a touch-tone pad, dial or the like, the data monitor decodes the signal and operates a relay associated with the identified line to couple that line to an audio buss; the information on the audio buss is then applied to the telephone line and transmitted back to the remote station where it can be monitored and any problem diagnosed.

Abstract: Abstract A flexible joint for a conduit transporting fluid under pressure includes a pair of spaced rigid rings. An annular flexible element is disposed between and sealingly engaging the rings so as to define a pair of annular exposed side surfaces on the element. One side surface is exposed to pressurized fluid flowing through the conduit, thereby creating a pressure differential across the flexible element between its side surfaces. To resist the load that results from the pressure differential, the flexible element in-corporates a body of elastomer that has a thickness between the rings which decreases from the one side surface of the element to the other side surface. The flexible element can thus resiliently accommodate relative motion between the rings, while providing a fluid-tight, pressure-resistant seal.

Abstract: Abstract of the Disclosure A machine for forming concrete slabs by a continuous process without using conventional casting forms.  This requires that the consistency of the concrete mix be such that the concrete will be self-supporting before it has hardened.

The machine includes a carriage that is advanced by winch and cable along a track over a flat surface.  A portion of the carriage coacts with the first surface to form a mold cavity, and concrete mix from a hopper mounted on the carriage is delivered to the cavity by a novel feed and packaging arrangement. Vibration means are associated with the mold cavity to con-solidate the concrete mix and improve its flow.

Abstract: ABSTRACT OF THE DISCLOSURE         A method of measuring a filling level in a container or the height of loose material over a storage surface, comprises transmitting and recording a sound pulse having a duration at least as long as a pulse which travels to the lowermost level of the material, recording the echo of the sound pulse from the actual material filling level, and measuring, as a measure of the filling level, the time interval between the end of the transmitted pulse and the end of the echo pulse.  A device for measuring the height of the filling material on a surface, comprises an electroacoustic trans-mitting  transducer excited by an electric pulse generator and having a receiving transducer whose output is connected to an electrical time measuring device.  The transmitting transducer and the receiving transducer are mounted over the surface of the material being added thereon and a control circuit of the measuring device is adjusted so that it starts measuring the time at the end of the transmitted pulse and stops at the end of the echo pulse.

Abstract: ABSTRACT         The method of treating open-celled polyurethane  foam by the application of a modifying ingredient, such as a dye, pigment, color stablizer or fire retardant, for example, wherein the method comprises the steps of (a) applying an excess of a liquid solution or dispersion of the modifying ingredient to a mass of the foam, (b) removing most of the excess of the liquid by squeezing the mass, (c) passing a gas, the temperature of which is between 350°F. and 500°F., through the material for a period of time sufficient (1) to raise the temperature of the polyurethane mass to a point at which the polyurethane will absorb the modifying ingredient, and (2) to vaporize the liquid present in  the solution or dispersion, the period of time being insufficient to cause charring of the polyurethane, thereby accelerating the absorption of the modifying ingredient into the polyurethane, so as to permanently incorporate the modifying ingredient into the foam, and (d) allowing the mass to cool.  The gas is chosen so as to be inert with respect to the foam, the modifying ingredient, and the liquid.

Abstract: IMPROVED SKID CONTROL SYSTEM        Abstract of the Disclosure:  A skid control system is provided for use with a vehicle having a pair of spaced apart wheels and having a braking system for applying braking forces to the wheels. A brake control circuit responds to a skid signal obtained from any one of a plurality of in-cipient detector circuits to act upon the braking system to release the braking forces. A delayed skid signal is provided whenever the difference in wheel speeds of the two wheels exceeds a given amount. A delayed skid signal is also provided if the average wheel speed of the two wheels de-creases at a rate greater than a desired decreasing rate. If both wheels decelerate, a skid signal is provided upon sensing that the faster wheel is decelerating at a rate greater than a reference rate. As the wheels spin-up toward an ideal velocity for a braked vehicle, an accelera-tion detector serves to insure wheel roll up on low friction surfaces. If the wheels spin up at an acceleration greater than an acceleration level, the acceleration detector output is inhibited. If the acceleration is less than the preceed-ing level and more than a second level, a skid signal is provided. Also, as the wheels spin-up to a desired velocity, braking forces are restored when the rate of acceleration declines below second acceleration level. Monitoring circuits are provided for monitoring various operations of the skid control system and deactivate when the operation is not within prescribed limits.

Abstract: DIGITAL TONE DECODER SYSTEM                         ABSTRACT      The digital tone decoder system includes a phase locked loop which receives an input tone signal, which may be accompanied by noise, and produces a replica of the input signal from which the noise has been filtered.  The tone signal operates a gate to pass clock pulses from a reference oscillator into a counter for precisely N cycles of the tone signal.  The counter provides digital period information of the tone signal which is compared with period (frequency) information of the tone or tone sequence to which the detector system is to respond provided by an address code element.  A logic control circuit is activated when lock is acquired by the loop, and this control circuit initiates operation of the other parts of the system and produces the detector output.  The clock pulse oscillator also provides system timing and alert tone signals.  The detector is capable of decoding and identifying any N-tone signal sequence or group of sequernces by use of the required address code element or elements, with the logic control circuit providing the appropriate timing.
