Abstract: A method of making a biodegradable non-polluting product includes grinding an agricultural fibrous material to form a particulate material; preparing a binder by mixing formaldehyde with carboxymethyl cellulose and polyvinylalcohol; mixing the particulate material with a stearate and a sulfate to form a first mixture; adding the binder and water to the first mixture to form a second mixture; and forming the second mixture into the non-polluting product. The fibrous material may be an agricultural fibrous waste material. The products made by the method contain no toxic material.

Abstract: An agricultural solid waste composition contains 81-90% by weight of a powdered agricultural solid waste, 9-15% by weight of water, and 1-4% by weight of a binder. The binder contains 85-95% by weight of a gel material, 2-7% by weight of a sulfate, 2-7% by weight of a stearate, and 0.5-2% by weight of a skin forming agent. The skin forming agent contains 75-85% by weight of the gel material, 6-10% by weight of calcium chloride, and 9-15% by weight of alum.

Abstract: A dual-chamber safety hypodermic syringe. The syringe includes a barrel having a medicine chamber, a needle chamber, and a guide hole connected between the chambers. The needle assembly is moved in and out of the needle chamber between the extended position where an inlet on a neck of the needle assembly is disposed in communication with the guide hole for enabling liquid medicine to be squeezed out from the medicine chamber through the needle cannula of the needle assembly, and the received position where the needle assembly is safely received inside the needle chamber and kept from sight.

Abstract: A method of making a non-polluting product includes the steps of: (a) obtaining an agricultural fibrous waste material; (b) drying the fibrous waste material; (c) grinding the fibrous waste material to form a powder; (d) mixing the powder with a binder in a mixer to form a mixture, the binder including polyglycol, cellulose and formaldehyde; and (e) forming the mixture into the product. The product produced by the method is a non-polluting inexpensive product since agricultural waste, which is recycled, can decompose naturally without leaving any toxic residue.

Abstract: A capped container is disclosed, which includes a container body, a nozzle, a cap, and retainer means provided between the inside wall of the cap and the shoulder or nozzle tip of the nozzle for enabling the nozzle to be press-fitted first into the cap and then fastened to the opening of the container body with the cap. When holding the cap to aim the nozzle at the opening of the container body, the punch of an automatic machine is pressed on the top of the cap to force the nozzle into engagement with the opening of the container body without causing damage to the nozzle.
