  • Patent number: 4647336
    Abstract: An assembly for providing support to a component, such as an ultrasonic component, including converters, boosters and horns which are subjected to continuous and repeated impacts and stresses. Such devices generally have integral nodal flanges for support purposes. In this assembly, shock-absorbing means are placed on each side of the nodal flange. A grip ring assembly is then bolted or otherwise removably fastened, together over the shock-absorbing means and nodal flange, compressing the shock-absorbing means. The component is prevented from rotating with respect to the grip ring assembly by pegs which are driven through holes provided in the grip ring assembly and into slots formed lengthwise in the nodal flange. Hence the flange itself, via the shock-absorbing means, absorbs all of the lengthwise force applied to the component by the grip ring assembly, and the pegs are required to absorb none of it.

  • Patent number: 4589060
    Abstract: A microcomputer system and method for controlling the capacity of a refrigeration system are disclosed. The microcomputer system receives electrical input signals indicative of operator selected settings and refrigeration system operating parameters. The microcomputer system processes these input signals to generate a control signal which is a step function of the temperature difference between a desired set point temperature and the sensed temperature of a heat transfer fluid cooled by operation of the refrigeration system. The width of each step of the step function is directly proportional to a selected capacity control response factor. By selecting different capacity control response factors, capacity control of the refrigeration system is tailored to meet specific job requirements of a particular job application for the refrigeration system.

  • Patent number: 4539820
    Abstract: A protective capacity control system and method for controlling the capacity of a refrigeration system are disclosed. The protective capacity control system receives electrical input signals indicative of operator selected settings and refrigeration system operating parameters. These input signals are processed to generate a control signal which is a step function, preferably having two steps, of the temperature difference between a desired set point temperature and the sensed temperature of a heat transfer fluid cooled by operation of the refrigeration system. The capacity of the refrigeration system is reduced at a first effective overall rate to provide capacity control which will reduce hunting by the capacity control system when the sensed temperature of the heat transfer fluid cooled by operation of the refrigeration system is less than a lower limit of a selected temperature deadband relative to the desired set point temperature.

  • Patent number: 4538422
    Abstract: A method and control system are disclosed for minimizing the number of recycle starts of a compressor in a refrigeration system to thereby reduce wear and tear on the mechanical and electrical systems of the refrigeration system thereby prolonging the operating life and improving the reliability of the refrigeration system. The rate at which the refrigeration system compressor's capacity is increased upon the recycle start is greatly reduced compared to a normal, relatively fast rate of increase which is provided when the capacity of the compressor is controlled directly in response to the load placed on the refrigeration system. This prevents the refrigeration system from quickly satisfying a new, increased load placed on the refrigeration system upon a recycle start which will then require a relatively quick shutdown of the refrigeration system compressor due to excess cooling capacity and require a relatively quick subsequent recycle start of the compressor.

  • Patent number: 4535607
    Abstract: A method and control system are disclosed for minimizing the number of recycle starts of a compressor in a refrigeration system to thereby reduce wear and tear on the mechanical and electrical systems of the refrigeration system thereby prolonging the operating life and improving the reliability of the refrigeration system. By limiting the load placed on the refrigeration system upon a recycle start the rate at which the refrigeration system satisfies the load is significantly reduced compared to a normal, relatively fast rate of satisfying the actual load which usually occurs when the capacity of the compressor is controlled directly in response to the actual load placed on the refrigeration system.

  • Patent number: 4531375
    Abstract: A refrigeration system is disclosed having a purge system with means for monitoring operation of the purge system and for taking corrective action in response to excessive purge system operation. Preferably, the monitoring means is a microcomputer control system for monitoring purge pump operation to determine if the purge pump has operated continuously for a period of time greater than a predetermined amount of time. If the purge pump has operated continuously for a period of time greater than the predetermined amount of time, then the microcomputer control system overrides normal purge pump operation and maintains the purge pump inoperative for a selected time period before attempting to resume normal operation. The microcomputer control system counts the number of consecutive times that normal purge pump operation is overridden and totally disables the purge system if the number of consecutive overrides exceeds a preselected number.

  • Patent number: 4514989
    Abstract: A method and control system for protecting an electric motor driven compressor in a refrigeration system are disclosed. The refrigeration system operates to satisfy a load placed on the system and the refrigeration system compressor is turned off when the load is satisfied and the refrigeration system is providing excess capacity. When the compressor is turned off due to excess capacity, current flow to the electric motor driving the compressor is sensed and the refrigeration system is shut down if the sensed current flow is abnormal. In this manner, the compressor and the electric motor driving the compressor are protected against restarting under unfavorable operating conditions which could unduly wear the compressor motor and/or the compressor.
