摘要： Apparatus for melting and dispensing thermoplastic material including a hopper for receiving solid thermoplastic material, a flow-through grid melter secured to the bottom of the hopper and a heated reservoir mounted beneath the grid melter. The reservoir has a bottom discharge opening through which molten thermoplastic material is supplied to a pump. To control the temperature of molten material supplied to the pump, there is a deflector shield over the bottom discharge opening of the reservoir. This shield has downwardly and outwardly sloping top surfaces operable to force molten material falling onto the shield to flow outwardly over the top surface of the shield and then downwardly and inwardly over the top surface of the bottom wall of the reservoir before flowing into the outlet opening of the reservoir. To input desired temperatures for the grid and reservoir into the apparatus and to read out temperature data, there is a control console mounted atop the housing of the apparatus. This console is pivotally and vertically adjustable and facilitates operator interface with the apparatus.

摘要： A method and apparatus for dispensing a foamable, pressurized solution of a gas and a high viscosity polymeric material in a manner which produces a foamed bead having a hollow core. Initial foaming occurs in a nozzle through which the solution is dispensed to atmosphere, at a core of the bead. Subsequent foaming of of the bead exteriorly of the core occurs outside the nozzle, and results in an extruded, foamed bead of high viscosity polymeric material having a tubular shape and particularly suitable for form-in-place gasket applications.

摘要： A dispenser which prevents dripping and drooling of liquid material upon shut off of the dispenser, especially during intermittent dispensing operations. The first embodiment includes a nozzle body and nozzle fitting which include liquid flow passageways and together form an air passageway which communicates with a discharge passageway upstream of the discharge end of the nozzle fitting. Exhaust air from the dispenser is directed into the air passageway such that excess liquid material is blown out of the discharge passageway and off of the discharge end of the nozzle fitting immediately upon shut off of the dispenser. A second embodiment incorporates this anti-drip and anti-drool feature directly into the valve and valve stem of the dispenser by providing the air passageway through the valve and valve stem.

摘要： A solar-powered parking space barrier block is configured as a one-piece molded housing of a high strength, transparent plastic material in which a photovoltaic solar panel and a DC energy storage module are inclosed. A pair of white light LED lamps provide end panel marker illumination, two yellow light LED lamps provide hazard warning illumination and a rechargeable supercapacitor storage module provides operating power. A power control circuit enables use of the solar panel as a photosensor to automatically energize the LED lamps when ambient skylight falls below a predetermined safe visibility level, and removes operating power from the LED lamps when ambient skylight rises above a predetermined safe visibility level.
