  • Patent number: 4090622
    Abstract: A rotary retort furnace wherein the retort is supported for rotation at only one end outside of the heated furnace shell such that the retort is cantilevered into the shell. The rotary retort has a charging door mechanism that cooperates with a skip hoist loading mechanism to provide charges of the parts to be heat treated that are of a uniform size and are introduced into the retort so as to minimize the loss of any controlled atmosphere. The skip hoist loading mechanism has a vibrating feed hopper that dispenses a weight controlled charge into a skip hoist bucket which, after receiving the predetermined charge of parts, is held in a ready position until such time as a cam mechanism controlling the opening and closing of a door on the charge end of the retort causes the door to open and the skip bucket to be moved to a position wherein the parts are dumped into the retort for heat treating.

  • Patent number: 4091317
    Abstract: A variable delay windshield wiper control system is provided in conjunction with a conventional windshield wiper system of an automobile to control the operation wiper drive source and wiper drive mechanism at predetermined variable intervals. The variable delay wiper control system operates independently of the conventional wiper switch and is effective to provide an adjustable delay interval between successive windshield wiper sweeps or reciprocative paths as is desirable during light rain or precipitation conditions.The wiper control system includes a timing circuit which generates variable duration intervals and directly effects operation of the drive source at the end of each of the intervals, and a delay control adjusted by the operator. A control switch is also provided for disabling the variable delay wiper control system and for effecting operation of the timing circuit.

  • Patent number: 4082941
    Abstract: A bag sealer having an electrically heated wire and a pivotally mounted sealing member which is substantially parallel to and normally biased away from the wire. An integral transformer and solenoid are provided for reducing the voltage supplied to the wire and for bringing the sealing member into pressure bearing relationship with the wire. The primary winding of the transformer serves as the solenoid coil while the solenoid armature, upon being closed, completes the transformer. In order to facilitate activating the switch to energize the transformer winding, a lever extends out through the housing. Molded side pieces carry an extruded channel on which is mounted a resilient pressure bar.

  • Patent number: 4079528
    Abstract: A steam iron is provided with a feed valve to supply water to a vaporizing chamber. The feed valve comprises a valve member of metal which is encased in a plastics part, both the valve member and plastics part having a through flow aperture which supplies water to the vaporization chamber in response to operation of a valve stem. The said plastics part is so shaped and arranged that it extends into the vaporization chamber. In this way deposits of lime on the outer surface of the plastics part is avoided and movement of the valve stem in the aperture prevents lime deposits on the stem or in the aperture.
