A susceptor-impregnated thermoplastic foam is molded by heating the susceptor-impregnated thermoplastic foam, preferably by induction; imprinting an object against the foam; and allowing the foam to cool into a hardened form conformed to the object.

Apparatus for manufacturing heat sealed products from high temperature film materials exhibiting superior barrier properties, such as films made from LCP resin. The apparatus has in relevant part a first compression member having a heating element that is capable of being continuously or intermittently heated to a temperature of about 300.degree. C. (c. 575.degree. F.) backed by a layer of material capable of supporting the heating element, a second compression member that opposes the first compression member and having an electrically conductive tubular sealing element, capable of being flash-heated by means of a pulse of electric current to a temperature of about 425.degree. C. (c. 800.degree. F.) and immediately flash-cooled to room temperature or below by means of forcing vortex-chilled coolant fluid through the tubular lumen, backed by a layer of material capable of supporting the sealing element, and two floating sheets or tapes of high-temperature release material disposed therebetween.

An acoustic enclosure (10) has interconnected sound reducing panels forming a substantially rectangular structure which is configured to house a computer printer. Each side (12,14) panel is a multiple strata panel having an outer polymeric stratum (26), a multiple channel intermediate thermoplastic stratum (28) and an inner open celled acoustic material stratum (30). The rear and bottom panels (16, 18) are multiple stratum panels, having multiple channel intermediate thermoplastic stratum (46) which is sandwiched between inner and outer polyurethane foam strata (44,48). An adhesive material (42) is provided for bonding the outer stratum to the intermediate stratum and the intermediate stratum to the inner stratum for each of the panels. An angle member (62) affixed to the intermediate stratum is provided for joining adjacent panels of the enclosure. A rigid thermoplastic hinged cover (22) having a uniform bend (52) is provided for closing the enclosure.

Impulse sealing apparatus having a forced cooling cycle following the impulse heating cycle, and comprising in combination, a vortex tube which converts a source of compressed gas at ambient temperature into a cold gas stream, a heat exchanger cooled by the cold gas stream generated by the vortex tube, a second source of pressurized ambient temperature gas communicating with the heat exchanger and cooled thereby, and means for removing the second source gas stream from the heat exchanger and communicating with the impulse sealer for supplying chilled gas thereto.

Impulse sealing apparatus

A method for making irrigation conduits comprises the steps of perforating a first sheet of plastic film by repetitively forming rows of holes in the cross-machine direction, positioning a fabric strip over the holes, positioning a second sheet of plastic film under the first, sealing the fabric strips and the sheets of plastic film together by forming a plurality of fused seals running in the machine direction, and slitting the seals lengthwise to separate the resulting conduits.
