  • Patent number: 6125642
    Abstract: This oil level control device is for a refrigeration system, the control device being attached between the compressor and the oil supply. The control device includes a housing having an inlet communicating with the oil supply and an outlet communicating with a compressor sump; and a solenoid valve controlling flow from the oil supply into the compressor sump. A sensing chamber having a fixed probe providing a proximity detection system detects the oil level in the sump and responds to a change in the complex permittivity of the oil as the oil level rises and falls to generate a signal that controls the supply of oil to maintain the oil level in the compressor. Circuitry is provided having an input connected to the output of the sensor and an output connected to the solenoid valve.

  • Patent number: 6026746
    Abstract: In offset presses in which the printing cylinder is provided with a tensioning spindle or reel rod the printing plate usually has a hooked edge which is inserted in a gap in the printing cylinder. The printing plate is then wrapped around the plate cylinder for insertion in the spindle within the plate cylinder. The tensioning spindle carries a slot for receiving an end of the printing plate. After insertion of the plate end in this receiving slot partial rotation of the spindle tightens the printing plate. A substantial amount of skill is required to fix a printing plate on a printing cylinder. It is not easy to align the gap in the printing cylinder with the slot in the tensioning spindle. Two hands are usually required. Herein the tensioning spindle end shaft carries a pinion capable of moving a rack associated with it when the tensioning spindle is partially rotated. A spring is installed to oppose the rack movement.

An entertainer needs to be able to almost instantly adjust the height of his microphone. The stand herein includes a height adjusting means which operates more quickly. It includes telescopically related outer and inner members, and also means for readily locking the upper inner member within the lower outer member.
