Abstract: A device for controlling the rate at which air is exhausted from a textile drying oven including means for withdrawing gas from the interior of the oven, a heater for heating the withdrawn gas, a catalyst bed for combusting the heated gas, a differential thermocouple for measuring the difference in the temperature between the gas entering the catalyst bed and the gas leaving the catalyst bed and means for varying the rate of exhaust from the oven in response to variations in the temperature difference across the catalyst bed.

Abstract: A device for scrubbing carpets having two angularly oscillating scrubbers with recessed portions arranged so that as the scrubbers angularly oscillate, they scrub overlapping areas but do not collide.

Abstract: A device for sculpturing pile fabrics which have been treated by stiffening the fibers thereof in selected regions. The device includes means for advancing the fabric, a support and a blade which severs the stiffened fibers as they pass over the support but allows the unstiffened fibers to deflect away from the blade.

Abstract: Apparatus for controlling the transfer of a continuous cord including a first roll means, drive means for the first roll means, a second roll means pivotably mounted adjacent the first roll means, position-detecting control means operatively connected to the second roll means and means for changing the speed of the drive means in response to changes in the control means.

Abstract: Apparatus for forming a tire reinforcing belt by positioning continuous cord on a movable support surface in a zigzag pattern including a traversing guide member, drive means for moving the support surface and for traversing the guide member, cam means operatively connecting the drive means and the guide member, and moving means for changing the position of the guide member and the cam means with respect to the support surface.

Abstract: Apparatus for coordinating the transfer of two continuous cords or strips includes a first roll for delivering a first cord or strip, a second roll for delivering a second cord or strip, a drive for the first roll, a drive capable of operating the second roll at speeds different from that of the first roll, and a tension-detecting control arrangement for detecting changes in the tension of the cord or strip being delivered by the first roll and changing the speed of the second roll in response thereto.

Abstract: An endless reinforcement comprising a unitary strip positioned across the width of the reinforcement from one side to the other at an angle to the edges of the reinforcement, the unitary strip including a multiplicity of continuous filaments surrounded and separated by rubber disposed in a contiguous undulating relationship throughout the length of the strip. Also, apparatus for forming a unitary strip including interdigitating gripper means arranged in an oval path, means for advancing the gripper means around the oval path, and means for increasing the degree of interdigitation of the gripper means during a portion of their advancement around the oval path.

Abstract: A powder spreading device comprising a powder storage bin, a foraminous wall discharge area, and within the bin a cylinder of resilient reticulated foam which can be rotated, and which is in pressure contact with said plate is disposed to press and wipe against the foraminous wall discharge area thereby urging the powder through the plate, deposits a uniform layer of powder on a substrate.

Abstract: Cutting apparatus including an anvil portion having a slot therethrough, a rotatable knife portion disposed within the anvil, anvil support means swingable from an operating position to a rest position, positioning means for moving the anvil support means into an operating position and knife actuating means for rotating the knife within the anvil when the anvil is in an operating position.
