Abstract: The invention includes a compositon of matter comprising a heavy oil having dispersed therein surface modified solid wherein said surface modified solids comprise solids having adsorbed thereon air oxidized polar hydrocarbons from said heavy oil and wherein said surface modified solids have a diameter of about 10 microns or less and a method for preparing the same.

Abstract: A night lamp includes a lamp that is fitted to a lamp holder, on the lamp holder and in front of the lamp is installed a semi-transparent obstructing plate, in the front of the lamp holder is a light sensitive resistor, in the rear of the lamp holder is a plug that can be inserted into a household power supply socket, the light sensitive resistor on the lamp holder will sense the outside light source, so that it will automatically light on the lamp on the lamp holder; characterized in that at the rear of the lamp holder is a cylinder, on the bottom of its inside are a center contact point and a ring contact point, inside the cylinder is a turning disc, on the turning disc are two conductive pins, the two conductive pins are respectively in contact with the center contact point and the ring contact point; on the bottom side in the cylinder is a jutted point, on the bottom of the turning disc are no less than four equally spaced positioning holes, the jutted point will be accommodated in one of the positioning

Abstract: A safety faucet including a handle having an opening, a safety sliding block received in the opening on the handle, a casing, and a valve device mounted within the casing, the valve device including a cap fastened to the casing, a valve stem having one covered end with a water stopper and the other end extended out of a hole on the cap and pivotally secured to the handle, and a spring mounted around the valve stem and disposed inside the casing, when the safety sliding block is pressed with the handle to engage projecting plates of the block against the top cap, the valve stem and the water stopper can be lifted by the handle to open the water passage through the casing.

Abstract: A vacuum ejector includes an air ejector connected to a vacuum pump by a tube and controlled by a control switch to withdraw air from a food container. The air ejector includes a cap for covering the food container, a plug fastened to the cap by a screw joint, a valve received within a top recess on the cap and coupled to the plug to control the air passage between the food container and the vacuum pump, and a connector detachably connected between the plug and the tube being connected to the vacuum pump. The vacuum effect can be achieved quickly and conveniently for keeping the food fresh or for other vacuum treatment.

Abstract: A heat sealing apparatus includes a top recess on the base, and an arched hole on one side of the rear of top recess; the cover includes a notch on the rear side thereof corresponding to the arched hole of the top recess on the base; a clip is received within the top recess on the base, including a fastened guide tube that comprises a front and a rear end respectively extended out of the clip, the rear end of guide tube being inserted into the arched hole on the base and connected to a vacuum ejector; in operation, the plastic bag first be sealed with a small opening unsealed, then the clip with suction pipe is moved out of the heat sealing apparatus, inserts the guide tube into the small opening of the plastic bag and clamps the bag for suction operation; after suction, the clip with the plastic bag is moved back to the sealing unit and the small opening of the plastic bag is completely sealed.

Abstract: The present invention relates to an improved faucet structure which is changing the conventional manner of vertical, up-and-down, spiral control of turning on and off water flow into the novel manner of plane rotary control, the entire opening and closing of the faucet can be achieved via rotating about 90.degree. thereof. Therefore, the operation is much more convenient and laborsaving as well as durable and practical than ever before since the rubber washer subject to more even force is uneasy to be damaged.

Abstract: Parisons are injection molded using a cooled cavity and a relatively hot core pin to prevent the formation of residual internal stress in or near the inner surface of the parison. The parison is promptly transferred while still hot from the injection mold to a temperature conditioning station to provide a desired temperature distribution and the temperature conditioned parison is highly molecularly biaxially oriented as it is blow molded.

Abstract: Parisons for use in making blow molded highly molecularly oriented plastic bottles are injection molded using a cooled cavity and a relatively hot core pin to prevent the formation of residual internal stress in or near the surface of the parison. The pin is maintained at a temperature above the glass transition temperature of the resin to reduce the formation of cracks when the parison is subsequently blow molded in the orientation temperature range.
