Abstract: The weather parameter display system includes a visual display and at least one weather parameter sensing module positioned inside or outside a building for sensing or measuring and obtaining an indication of a weather parameter. Each weather parameter sensing module has circuitry for receiving a signal, circuitry responsive to the received signal for sensing a weather parameter value and circuitry for transmitting the value of the weather parameter sensed. A remote control is provided having circuitry for causing the sending of a signal which will cause actuation of the weather parameter sensing module to cause a reading to be taken of the value of a weather parameter and to be transmitted. Further there is provided circuitry associated with the visual display for receiving the transmitted weather parameter value signal and for causing the weather parameter value to be displayed on the visual display.

Abstract: The automatic self-filling bird feeder comprises: a container for receiving bird seed, an electrically powered blower mounted in the container and having an air outlet for supplying pressurized air to the interior of the container; a seed filling opening in the container for supplying seed to the container; a cover for the seed filling opening; a tube assembly extending from the container; an enclosed bird feeder housing mounted to the outer end of the tube assembly; circuitry for sensing the level of seed in the seed container; and circuitry responsive to the level of seed sensed in the bird feeder housing for controlling the operation of the electrically powered blower.

Abstract: The plastic extruder assembly is of the type that includes an extruder barrel assembly and an extruder die chamber in the distal end of the extruder barrel assembly. The die chamber has means for receiving and mounting a die assembly therein and the die assembly has die holes extending therethrough to an outer face. A layer of insulating material is provided beneath the outer die face at least in the area of the die holes for inhibiting if not altogether preventing freezing of the plastic in the die holes. Also, radial and circumferential hot oil passageways are provided in the die assembly and the die holes are offset in either a concentric array or a series of spirals.

Abstract: The pelletizer comprises a chamber having a first side and a second side coupled to an extruder. A shaft extends through the first side into the chamber, a rotatable cutter assembly is mounted to the end of the shaft in the chamber and a die assembly is mounted at the second side of the chamber and has a die face facing into the chamber. The cutter assembly is positioned for rotation adjacent the die face. A prime mover is coupled to the shaft for rotating the cutter assembly. Plastic material is extruded through holes in the die assembly into the chamber as the cutter assembly is rotated to cut plastic streams coming out of the die assembly into pellets. A position control assembly automatically controls the position of the cutter assembly adjacent the die face. The cutter assembly has a plurality of cutting blades mounted thereon.

Abstract: The extruder assembly includes a barrel, a screw received within the barrel, a motor drive and transmission connected to one end of the screw for driving same and an extruding die at the other end of the barrel through which material is forced by the screw. The barrel has a slot therein and the assembly further includes a ram feed assembly having two pivotally mounted ram sections positioned on either side of the barrel for forcing molten plastic through the slot into the barrel. The ram sections are pivotable between an upper operating position and a lower exposed position providing easy access to the ram sections for cleaning and maintenance thereof.
