  • Patent number: 5139081
    Abstract: This invention discloses an extremely simple chemical heat pump system utilizing the chemical reaction heat of a perfectly reversible chemical disassociation reaction system wherein one gaseous compound is involved in the reversible reaction. The present system can realize a large coefficient of performance over a very attractive temperature range and level for general use, by absence of any phase transition. Reaction kinetics of the system are excellent since only one reversible non-flammable gaseous compound is involved in the chemical heat pump system. The system can be provided with a computer controlled system for changing the restriction value of the expansion valve. The system utilizes jet ejectors in combination with the compressor in the same or different loops to reduce the capacity requirements on the compressor.

  • Patent number: 5107729
    Abstract: A torque multiplying wrench having a jaw at one end and an adaptor at the other end for receiving torque input. The wrench employs a rotatable shaft extending the length of the wrench with bevel gears at the proximate end to engage the input adaptor and a bevel gear arrangement at the distal end to transfer torque from the shaft to the jaw which is toothed. The bevel gear arrangement at the distal end of the wrench employs a pair of shafts engaged at one end to said rotatable shaft through bevel gears. The shafts fan out to opposite sides of the jaw and employ worm gears to transmit the output torque to the jaw. The worm gears are especially designed to increase the number of teeth engaged with the jaw in order to reduce the load on individual teeth.

  • Patent number: 5079417
    Abstract: A failsafe or self-monitoring sensing edge for an overhead door comprising a channel mounted on the bottom edge of the door having a pair of downwardly extending arms which are spaced. An outer covering of soft material is attached to said channel for enclosing the arms. The covering supports within a rigid member extending upwardly through said arms terminating in an actuating member. On one end of the channel is a light source and the other end is a photoswitch. When the covering is depressed upwardly as a result of an obstacle in the path of the door, the actuating member blocks the light beam and the photoswitch gives off a signal which can be used to terminate or reverse motion of the door.
