    摘要: The invention is a method for rebuilding grey cast iron ingot moulds that have a cavity erroded therein and the concept is to fill the cavity with cast iron from a tubular wire supply by electric arc deposit at a rate such that the heat supplied by the electric arc deposit is sufficient to prevent chilling of the cast iron that is deposited whereby on cooling the cavity is filled with substantially graphitic cast iron.

    摘要: A hand-held personal cleaning device is provided for allowing users with limited upper body mobility to clean hard to reach areas after using the restroom. The device comprises a handle having a grip, a working end having a grasping means, and a rigid curved tube secured therebetween. A first button disposed on the inside of the handle grip allows a user to open and close the grasping means located at the working end. The grasping means is used to retain and release a tissue loofah. A second button is located on the underside of the handle and may be used to disburse liquid from a reservoir within the handle onto the tissue loofah. A user may then maneuver the device and use the loofah to wipe his or her hard to reach areas. The loofah may then be disposed of by depressing the trigger button again, releasing the loofah for disposal down a drain or in a waste basket.

    摘要: A sensing system for use in a garage or other similar enclosure having an automatic door operator for automatically opening a garage door responsive to a lack of sufficient oxygen therein including a gas detector located within the enclosure responsive to actuate a detection relay which in turn will close a normally open detection switch, the closing of the detection switch will normally cause operation of the door operator to allow oxygen to enter into the enclosure through the door opening, the detection switch being located in a door opening control circuit which includes therein a first limit switch which is open whenever the door is open in order to prevent actuation of the door operator when the door is already open, the door opening control circuit also including a delay clock and delay switch which will be normally closed to allow operation of the door operator, this system also including a time delay circuit with a second limit switch therein which is adapted to be normally open and to close only when the door is open, in this manner the second limit switch which will close when the door opens will cause actuation of the delay clock which will open the delay switch to prevent operation of the door opener for 5 minutes after the door has been opened and then closed, this system may also include a sensing lamp to be lighted whenever the gas detector is actively monitoring and also to alternatively include a detection indicator lamp which is adapted to be lighted responsive to the emitting of an electrical signal by the gas detector, the door opening control circuit in this configuration will cause opening of the door by actuation of the door operator whenever the gas detection means senses a low level of oxygen in the environment of the enclosure assuming that the door is not already in the open position.
