Abstract: A clamp for clamping heater assemblies onto cylindrical bodies such as injection molding nozzles that require heating. The clamp includes a mandrel that slips over the nozzle, and has a heater wound on the exterior. The mandrel has a longitudinal slit that will permit the bore of the mandrel to be reduced in size when a lateral width of the slit is reduced. The mandrel carries outwardly facing cam surfaces, and an overlying sleeve has inwardly facing cam surfaces which mate, and upon relative longitudinal movement, the cam surfaces cause the lateral width of the slit to reduce and clamp the mandrel onto the nozzle. The clamping can be effected by differential movement due to differences in thermal expansion of the mandrel and the sleeve, or by mechanical movement of the sleeve relative to the mandrel to obtain the cam action.

Abstract: A pellet mill includes a conditioning section which mixes dry material, moisture in the form of water, and heat provided by a hot air system for the creation of a mash suitable for pelleting without the use of steam. The hot air section inputs heat by utilizing a blower which pressurizes air across a heat exchanger and into a plenum which interconnects an air duct with the conditioner. Moisture is input to the conditioner with a hot water system which modulates the flow of water and temperature of the water as it is sprayed onto the dry material. An automatic controller controls the process in accordance with temperature measurements made at various points in the pellet mill to select a desired operating temperature or in accordance with other control parameters previously developed.

Abstract: A method of shaping a soap bar comprising the steps of obtaining a soap bar, placing the bar in a microwave oven, energizing the oven with sufficient power and time to soften the bar, and forming the softened bar into a desired shape and size.

Abstract: This transfer nozzle consists of a nozzle body with a disk type cylindrical center part (21) and two axial nozzle cones (22,23). On a part of their height the nozzle cones (22, 23) are embraced by a sleeve-like collar (25, 26) and within the collars there are several axial passage openings (27, 28). A radial passage opening (30) through the center part (21) serves to receive a heating cartridge. The nozzle body (21, 22, 23) is supported by means of the outermost portions of the two collars (25, 26) on the one hand in the supporting basket (2) and on the other hand in the tool part (5), so that little heat can be lost to the cooled machine parts. The nozzle cavity (11) forms an air cushion around the center part (21) which also has a heat-insulating effect. Such a transfer nozzle has a low structural height and can keep the molding material warm from within, and by the axial arrangement of two nozzle cones the material is ejected with each molding.

Abstract: An apparatus for compacting a solid waste material includes a hollow cylindrical body having a charging inlet for charging the solid waste material therethrough into the hollow cylindrical body, a heating portion for heating the solid waste material in the hollow cylindrical body, and a discharging outlet for discharging the solid waste material from the hollow cylindrical body; a rotatable shaft disposed in the hollow cylindrical body and having a helical screw blade thereon, the screw blade and an inner wall surface of the hollow cylindrical body being spaced from each other with a clearance provided therebetween for allowing the solid waste material in the hollow cylindrical body to form a bridge therein; a support for radially movably supporting an end of the rotatable shaft; a prime mover coupled to the end of the rotatable shaft through the support; and an outlet nozzle coupled to the discharging outlet for compressing the solid waste material discharged from the discharging outlet.

Abstract: The thermoplastic shotshell reconditioning tool includes an elongated member having a front conductive tip portion adapted to be heated to a high temperature sufficient to melt the thermoplastic material of the shotshell tubular portion. A reduced diameter portion of the member is disposed rearwardly of the tip portion to retard axial heat transfer toward a rear handle portion. A generally cylindrical shell conditioning portion is disposed immediately rearwardly of the reduced diameter portion for receiving the heated mouth portion of the melted shell tubular portion to permit it to cool as the heated tip portion advances axially toward the base end portion of the shotshell. The outer surface of the tip portion is heated with a blow torch to a high temperature in the range of 250.degree. F. and 350.degree. F. The heated tip portion is manually inserted into snug contact with the crimped mouth portion of the expended shotshell to melt it for reshaping purposes.
