  • Patent number: 4147303
    Abstract: A heat-saving attachment in the nature of a jacket surrounding the smoke pipe of a furnace located in a basement or other relatively unheated space. Air is drawn from the unheated space or other area into the annular space between the jacket and smoke pipe, absorbing heat from the exterior of the pipe as it is directed through laterally disposed baffle means within the annular space from whence it is directed through a warm air duct to a space to be heated. Electrical controls may be provided to establish predetermined time delays between turning on and off of the furnace burner and respective on and off controls of an intake fan for drawing air from the unheated space into the jacket.

  • Patent number: 4147306
    Abstract: Foam is produced when a reservoir is deformed by squeezing. When pressure is applied to the reservoir, a flexible washer seals a vent passage while liquid is forced up through a tube, a ball valve and outwardly through a radially slotted member, while air passes through orifices in the washer and along the outside of the slotted member to mix with the liquid. The mixture is then discharged when pressure is released, the valve is sealed and suction pulls the washer away from the vent to allow air back into the reservoir.

  • Patent number: 4147311
    Abstract: A method for feeding a yarn to a textile machine selectively under conditions of positive and capstan feed. The method comprises wrapping multiple turns of yarn around a feed wheel and a smooth, straight-sided upstanding member alongside the feed wheel and inclined to the rotary axis of the feed wheel, and driving the feed wheel by frictional contact with a flexible tape that extends over only a part of the axial extent of the feed wheel. The positive feed mode is established by passing the yarn repeatedly through the nip of the tape and feed wheel. The capstan feed mode is established by feeding the yarn away from the nip. In either mode, separation of successive turns of yarn is achieved by the upstanding member, and when guiding the yarn from one mode to the other there is an axial movement of the yarn turns over the upstanding member to obtain free and unobstructed re-positioning of those turns on the said member.
