Abstract: IMPROVED ARRANGEMENT AND METHOD FOR ESTABLISHING        RADIO COMMUNICATION IN A SYSTEM                 ABSTRACT OF THE DISCLOSURE        Communication between a first radio transmitter and receiver and a second radio transmitter and receiver is provided by a system repeater.  An arrangement for each radio transmitter and receiver in the system establishes communication on a radio frequency channel selected from a plurality of such channels.  When an arrangement is in an idle or receiver mode, it causes the associated receiver to search the channels for a predetermined group tone or tones assigned to each receiver.  When the predetermined group tone or tones are received on a channel, the arrangement enables the associated tran-smitter and receiver on that channel.  When an arrangement is in a call originate or transmit mode, it causes the associated receiver to search for an idle or unused channel.  When an idle channel is found, the arrangement enables the associated transmitter and receiver on that channel, and causes the transmitter to transmit a busy tone and the predetermined group tone or tones so as to enable the other transmitters and receivers of the predetermined group on that same channel.

Abstract: "GROUND ROLLING FORWARDLY-DIRECTED ROTARY BALER"            ABSTRACT OF THE DISCLOSURE A twine assembly is provided in a rotary baler wherein fibrous material is formed into a cylindrical bale by rolling the bale along a support surface.  The twine assembly is automatically actuated by the bale once the bale has reached a predetermined size.  Rotatable means are provided which, on contacting the rotating surface of the bale, are themselves rotated to pay out twine in front of the sale.  The twine becomes trapped between the rotating bale and the support surface and thus wraps the bale through one or more rotations of the bale.

Abstract: Abstract of the Disclosure A heat exchange system is provided which transfers the heat from a fluid discharged from a device that utilizes a heated fluid, to fresh fluid in order to increase the tem-perature of the fresh fluid prior to feeding it into a heating tank.  Thus, less energy is required to heat the fluid in the heating tank prior to its introduction into the device which utilizes heated fluid.  After the heat has been exchanged, the discharged fluid is then expelled from the system.  A fluid trap controls the fluid level in the heat exchanger to assure maximum heat transfer capability.  An antisiphon valve is provided in the fresh fluid input of the heat exchange coil in order to prevent discharged fluid from contaminating the fresh fluid sources in the event of a rupture in the heat exchange coil.  The fluid trap is provided with a pressure activated gate valve which deactivates the fluid trap in the event that the fresh fluid intake pressure decreases below a predetermined level, and thus further prevents contamination of the fresh input fluid by the discharged fluid.

Abstract: ZERO ROTATION AND ZERO TORQUE DETECTOR AND METHOD FOR AN AC ELECTRIC MOTOR DRIVE                     ABSTRACT OF THE DISCLOSURE            A substantially zero rotation and substantially zero torque detector and method for an AC electric motor drive system is disclosed. The drive system includes an AC electric motor producing a rotation in response to an outgoing signal, e.g., drive current, of variable magnitude and frequency An actual rotation signal is generated and is proportional to the rotation of the AC electric motor or to the frequency of the outgoing signal. A rotation reference signal proportional to a desired level of rotation is established. A rotation difference signal representative of any reference between the rotation reference signal and the actual rotational signal is generated. A torque command signal is provided as a function of the rotation difference signal and is used to produce a frequency control signal and a current control signal. Alternatively, the torque command signal is generated proportional to a desired level of torque when the drive system utilizes a desired torque level as opposed to a desired rotation level. The outgoing signal, for example, the drive current is supplied to the motor at a frequency controlled in response to the frequency control signal and at a magnitude varied in accordance with the current control signal. In the case of a device system utilizing a desired level of rotation, the substantially zero rotation and substantially zero torque detector and method furnishes an idle control signal when the torque command signal and at least two of the rotation reference signal, the actual rotation signal, and the rotation difference signal are less than respect predetermined values. Alternatively, in  the case of a drive system utilizing a desired level of torque, the substantially zero rotation and substantially zero torque detector and method furnishes an idle control signal ABSTRACT OF THE DISCLOSURE (continued) when the actual rotation signal and the torque reference signal are less than respective predetermined values.  In either case, the idle control signal is effective to control an operation parameter or function of the drive system and indicates when the drive system is in the substantially zero rotation and substantially zero torque mode.
