Abstract: A method of manufacturing opening tabs for containers comprises providing sheet material, from which tabs are to be formed, with locating apertures. The sheet material is located within a printing machine and printed information is applied to the sheet material at predetermined locations. The pre-printed sheet material is then located on a forming machine and opening tabs are formed in the location of the pre-printed information and applied to can opening ends.

Abstract: A field installable device for a conventional heating and air conditioning system (HVAC) is provided which operates a blower fan in conjunction with a standard thermostat. Presently, HVAC systems operate in four modes: heating, cooling, off and fan "on". The device includes a multi-pole, multi-speed motor and a control operatively connected between the thermostat and the motor. With the fan switch in the "on" position and heating or cooling called for, the control causes the blower to operate at a high speed, which may be different for heating or cooling. When the pre-selected temperature is reached the particular thermal operation (i.e., heating or cooling) is stopped. The control switches the motor to a speed substantially slower than the operating condition speed to provide continuing air circulation until the thermostat again calls for thermal operation. With the switch in "auto" position, the blower operates similarly to present systems.

Abstract: A fiber filling system features a picking device for separating clumped fiber, that feeds to an air and fiber circulation chamber. The circulation chamber aerates and fluffs the separated fiber into a fibrous billow, which is then discharged to a stuffing chute. A stuffable article, such as a toy, pillow, or furniture cushion casing is attached to the chute and is filled with the fibrous billow in a metered amount.
