    摘要： A corrugated plastic panel is produced by providing a plastic panel corrugation device whereby a plastic material is extruded, a cooled extrusion is formed by passing the extrusion through a cooling roller assembly, a corrugated extrusion is formed by passing the cooled extrusion through a forming roller assembly when the cooled extrusion has reached its impressionable temperature range, a corrugated extrusion is passed through a pulling roller assembly when the corrugated extrusion has reached its hardening temperature range, and a corrugated plastic panel is formed by passing the corrugated extrusion through an extrusion cutting assembly.

    摘要： Methods and apparatus are disclosed for bending mono-axially or bi-axially stretched sheets of a thermoplastically deformable synthetic resin by heating one side of the sheet above the softening temperature of the resin while the temperature on the other side is beneath the softening temperature, whereupon the resin sheet bends by itself or can be bent with forming tools.

    摘要： A tapered sail batten comprises two external generally flat sheets, and an interposed corrugated core sheet, formed of a fiber reinforced synthetic plastic material. The depth of the corrugations in the core sheet increases progressively from end to end of the sheet, and the two external sheets are bonded to the peaks of the corrugations. The batten is elongated and the corrugations are transverse to the length of the batten.

    摘要： Method and apparatus for making tea or coffee for drinking comprising heaping tea in an extractor and subjecting successive areas of the heaped tea to periodic sprinkling during successive intervals of sprinkling, with cold tap water, each followed by intervals of wet-expanding the tea until the tea is substantially completely wet-expanded. The sprinkling intervals are timed to allow the wet-expanding to take place after each sprinkling of a same area and without collapsing of the wet-expanded tea. The tea resulting from the wetting is filtered out while removing air bubbles therefrom. The extractor has a sprinkler continuously driven during the sprinkling period and the filtrate is taken out through a pipe perforated axially extending into a filtrate-receiving container. The filtrate is delivered as a tea drink and may be stored in a glass container or the like for prolonged periods without loss of flavor. Coffee is made in the same apparatus by using powdered coffee sprinkled with cold tap water and wet-expanded, filtered while removing air bubbles therefrom and then stored for delivery as a drink. The extractor has a vacuum pump that controls the flow-rate with the filter of the extracted tea or coffee maintaining the tea leaves or coffee constantly immersed to insure freedom thereof from contact with the air.
