Abstract: A hydraulic control device for a closed type kneader, including a sealing surface pressure applying circuit for applying a sealing surface pressure to a sealing device for sealing a rotor accommodated in a kneading chamber, a drop door driving circuit for controlling an opening and closing operation of a drop door for closing a bottom surface of the kneading chamber, and a power circuit for supplying a pressure oil to the sealing surface pressure applying circuit and the drop door driving circuit. The sealing surface pressure applying circuit is connected to a pressure oil supply line in the drop door driving circuit for a closed condition of the drop door. Accordingly, when the application of the sealing surface pressure is unnecessary, that is, when the drop door is opened, the sealing surface pressure is prevented from being applied to the sealing device, thereby extending the life of the sealing device.

Abstract: In order to apply "hot melt" adhesives to thin plastic film labels for glass containers without distorting the labels, a "hot melt" adhesive which is thixotropic is melted at 350.degree. F. and is continuously worked to maintain its viscosity at a fairly low level while being cooled to about 110.degree. F., at which time it is applied to the label. The label is applied to the glass bottle and the resultant labeled bottle will have the property of being able to withstand pasteurization temperatures, as well as refrigeration temperatures, without having the label separate from the bottle.

Abstract: A water-wet polymer is extruded through a die plate. Free water formed by extruding action at the die plate is atomized and/or evaporated into an air stream. The die plate assembly discharges the rubber/moisture into a closely adjacent cone/funnel-receiver openly surrounding the die plate, and connecting to and discharging into a lesser diameter conveying tube. The die plate and surrounding funnel are enclosed by a chamber so that air, input tangentially into the enclosure, provides a swirling vortex air flow at the die plate assisting in severing and stripping rubber particles from the die plate.
