Abstract: Microorganisms or enzymes are immobilized by using polyvinyl alcohol to form beads containing a microorganism or an enzyme. An aqueous solution of about 10 to about 20 wt % polyvinyl alcohol containing a microorganism or an enzyme is reacted with an aqueous solution of about 3 wt % to saturated boric acid for a period of about 10 minutes to about two hours to form gelled spherical beads. The beads are then hardened by treatment with an aqueous solution of about 3 to about 20 wt % phosphoric acid or phosphate for at least 30 minutes. Preferably, the polyvinyl alcohol has a degree of polymerization of about 1000 to about 3000 and a degree of saponification of about 70 to about 99 mol %. In an alternative embodiment, the boric acid solution can contain the phosphoric acid or phosphate. The microorganism can be an acclimatized activated sludge microorganism from agricultural or industrial waste water. The beads can be used for removing inorganic nitrogen and organic carbon in waste water treatment or in processes for making biochemical products.

Abstract: An improved packing means for sealing water holes in molds includes a first and second pressure elements having flanks on both sides and holding therebetween a steel ring. A first and second rubber rings are respectively provided next to the first and second pressure elements. The first rubber ring, the first pressure element, the steel ring, the second pressure element and the second rubber ring are respectively fitted onto a threaded rod portion of a main seat. The packing means further includes a locking seat having an internally threaded rod at one end thereof and an upper end provided with a slot or Phillips head at the other end thereof. The locking seat is locked onto the threaded rod portion of the main seat by means of a slotted or Phillips head screwdriver. Upon tightening, the first and second rubber pressure elements will press against the first and second rubber rings to stretch them outwardly and the steel ring to expand and be positioned in place. The first and second rubber rings may be fitted into the water holes of mold to effectively stop the entrance of water.

Abstract: An improved coupling for an air hose of a diver's jacket includes an outer sleeve with one end fitted onto one end of the air hose, the outer sleeve having an inner tube with multiple annular teeth locked therein, such that the air hose is tightly clamped therebetween. The other end of the outer sleeve is connected to a coupling which has a restriction ring and multiple steel balls provided at one end thereof. The coupling may be speedily connected to a fastening element of the air hose. The coupling accommodates an air intake element one end of which has multiple intake holes circumferentially provided thereon and a groove for receiving an oil ring, the other end of which is a raised stop portion. The air intake element may urge against an inner rim of the coupling by means of the oil ring due to the action of the spring prior to connecting the coupling with the fastening element, so that the inner wall of the coupling and the oil ring may block the intake holes. The fastening element has a pushing portion which may push the air intake element to displace out of the coupling to expose the intake holes to allow air through the air hose when the coupling is connected to the fastening element.
