Abstract: A kind of highly nondiaphanous nonowoven laminate consists of a inner black nontransparent lamina of non-thermoplastic long staple fibers and two outer laminae of thermoplastic fiber. It is processed through heating, press and bonding of the three laminae of fiber web together. Therefore, it possesses the properties of high nondiaphaneity, wrinkle resistance, good appearance and touch to hands and is very suitable for uses as screens, cover cloth and other non-transparent piece-goods.

Abstract: A knockdown indoor golf training course, which includes a teeing ground unit having a ball return gutter for guiding a golf ball back to a ball chamber and an elongated strip mechanism for guiding a golf ball to roll down to the ball chamber through the ball return gutter, and a counting net unit foldably mounted on the back side of the teeing ground unit to incorporate with a nested holder through several wire channels which extend from the various holes made on the net for counting the score and identifying the hole on the net a golf ball is driven in.

Abstract: A double hook-bolt unit lock includes a lock barrel having a revolving rod connected thereto to cause a cam wheel assembly to move simultaneously so as to drive the stop keys of a stop frame assembly away from the upper notched portion of a brake frame assembly and to let the cam wheel assembly move the brake frame assembly rectilinearly via a lower notched portion of the frame assembly. By means of the push force from L-shaped guide slots of the side plates of a lockcasing and the guidance of oblique guide slots of a brake frame assembly, the two L-shaped bolts which are movably connected to the brake frame assembly are driven to smoothly into respective locking positions to lock the door.

Abstract: A double hook-bolt mortise lock includes a cam form tumbler plate assembly comprised of a plurality of cam form tumbler plates driven by the steps of a key to define a space passage for passing therethrough of the key into a brake notch to further drive the cross bar of a main brake frame to move from one stop hole to the other. During movement of the main brake frame, an auxiliary brake frame is carried by means of two idle gears to make a rectilinear motion toward or against the main brake frame so as to drive the gears of two hook bolts to rotate, by means of the rack portions of the main and auxiliary brake frame, to further let the two hook bolts lock up with or lock from a striking plate.

Abstract: An injection cooling tower includes an injection tubular element having an elongated slit made thereon along axial direction through which a pressure forced hot liquid flow induced from outside is ejected to form into a continuous screen of high velocity liquid flow rapidly toward a diffuser wherein the kinetic energy of the continuous screen of high velocity liquid flow is converted into a pressure energy to result in a negative pressure to suck in cooled air current from outside so as to let the cooled air current mix with the continuous screen of high velocity hot liquid flow to start a heat exchanging process. The heat absorbed air current is further exhausted out of the tower through the top exhaust outlet where a mist eliminator is set, while the cooled liquid flow is guided by a turning vane to run into a bottom water storage tank from which the water is pumped by a water pump for further application.
