Abstract: A method for fabricating olefin tarpaulins by treating both sides of a base fabric woven from high strength polyester filaments with a coating composition using an extruder followed by compressing the coated polyester fabrics with a calendering roller. The coating composition is obtained by dry-blending or melt-blending LLDPE (linear low density polyethylene) or LDPE (low density polyethylene) in an amount of 15.about.94.5% by weight with an elastomer of ethylene-.alpha.-olefin co-polymer of 5.about.60% by weight which are (i) ethylene propylene rubbers or (ii) co-polymers of ethylene and octene or butene; coloring master batch chip in an amount of 0.5.about.15% by weight obtained by mixing LLDPE or LDPE with pigments or titanium dioxide; and adhesion-preventing master batch chip of 0.about.10% by weight obtained by mixing LLDPE or LDPE with silica or calcium carbonate.

Abstract: A plastic primary pan assembly for use in conjunction with an air conditioning system which includes a C-shaped drain plastic pan, a pan cover having a raised portion disposed around a blow outlet thereof, and an U-shaped supporting bracket having a pair of locking end members and a pair of elongated channels and an elongated aperture being mounted on the fan cover and a motor through a motor plate, whereby the plastic primary pan assembly can be easily associated with and separate from the air conditioning system and easily adjusted to incline the plastic primary pan for draining condensate water through an outlet disposed in the plastic primary pan.

Abstract: Plastic primary pan assembly for use in air conditioning systems which includes a base primary pan containing a pair of blind plates having a pair of semi-cylinders, respectively, to be removed one of them from the base primary pan, a pair of rubber packings, and an assembly plate having a pair of semi-cylinders to be inserted into the base primary pan, after taking out one of the pair of blind plates from the base primary pan, assembling with a base primary pan instead of the blind plate so as to pass a pair of built drain pipe therethrough, whereby the plastic primary pan can easily assemble the base primary pan with the assembly plate, the pair of rubber packings, and the pair of drain pipes.

Abstract: A plastic primary pan assembly for use in conjunction with an air conditioning system, wherein a channeled supporting bracket is utilized to tightly engage and effectively support a plastic pan which includes a drain plastic pan and a plastic support plate which contains a C-shaped circumferential portion and a C-shaped extending portion thereof, the channeled supporting bracket having a plurality of elongated apertures being mounted on a motor and a fan cover, whereby the plastic primary pan assembly can be easily associated with and separate from the air conditioning system and easily adjusted to incline the plastic primary pan for drawing condensate water through an outlet disposed in the plastic primary pan.

Abstract: A plastic primary pan assembly for use in conjunction with an air conditioning system, wherein a channeled supporting bracket is utilized to tightly engage and effectively support a plastic pan which includes a C-shaped circumferential portion having a pair of channels, the channeled supporting bracket having a plurality of elongated apertures being mounted on motor and fan covers which a C-shaped circumferential recess having a pair of rails for smoothly engaging with the plastic pan, whereby the plastic primary pan assembly can be easily associated with and separate from the air conditioning system and easily adjusted to incline the plastic primary pan for drawing condensate water through an outlet disposed in the plastic primary pan.

Abstract: A drainage pan for liquid waste containers which includes a Z-bar suction pump assembled with the wall thereof for draining the liquid waste leaked from a liquid waste container, an overflow drain pipe disposed at the upper portion of the wall thereof for draining liquid waste overflow leaked from the liquid waste container, and a plurality of gradually declining supports disposed on the bottom thereof for supporting a liquid waste container whereby the drainage pan prevents the liquid waste from contaminating humans or the ground.

Abstract: A primary pan assembly adapted to be mounted to the motor of an air conditioning system which comprises a primary pan provided with a drainage hole on at least one side thereof and stud members extending from the bottom thereof, a support bracket disposed to support the primary pan, height-adjustable brackets operatively connected with said support bracket at opposite end portions thereof for varying the height of said height-adjustable brackets relative to each other, said height-adjustable brackets containing apertures for slidably receiving the stud members of said primary pan, and a motor mount bracket for mounting the pan assembly to the motor, said motor mount bracket containing means for mounting the support bracket to said motor mount.
