Abstract: An air inlet and outlet passage module for desiccation is formed in a hollow structure including a frame and two boards. The frame has a frame channel formed between frame sides and a duct cap on an outer side. The duct cap has an opening communicating with the frame channel and is coupled with an air duct to connect a plurality of air inlet and outlet passage modules in series. The duct cap not being coupled is sealed through a lid. The two boards are located at two corresponding sides of the frame and have a plurality of air vents formed thereon to facilitate air ventilation. Each air vent is formed at a diameter smaller than that of a grain to prevent crops from dropping into the module. The invention can be assembled and disassembled, and coupled in series or parallel easily to enhance drying efficiency and reduce energy waste.

Abstract: The present invention is related to a 3D ventilation device for separating body skin from clothes including an elastic meshed fabric, an elastic framework and a fixing device, wherein the 3D elastic framework which supports and holds the elastic meshed fabric, is fixed by the fixing device to locate between the skin and the clothes, so as to form a ventilative chamber for achieving the separation. Here, the elastic framework can be bent to adapt to different body shapes or portions and adjusted to provide most comfortable wearing angle, so that a proper air flowing can be achieved between the skin or the body portion and the clothes, thereby keeping the skin dry.

Abstract: An apparatus and method for reposing and reviving a chemical battery include a single battery unit or a plurality of battery units clustered together. The output voltage of each battery unit is coupled in series or parallel to generate a greater voltage or current output. Every two battery units are isolated by an insulation plastic sheet. All battery units are connected through a serial and a parallel conductive wires to increase current or voltage. Final positive and negative outputs are delivered through a positive output terminal and a negative output terminal. All compound agent materials, the battery insulation film, and the central power collection plate are placed sequentially in a layer manner in a metal case which has an upper side covered by a seal plug.

Abstract: An improved hidden drain outlet structure for sink includes a drain pipe, a drain head screwed to the drain pipe at an upper end thereof and a filter movably screwed to the drain head. The filter may trap and collect external articles and garbage to prevent the drain pipe from clogging, and may be disassembled easily for repairs. The drain head and filter form a double curve-shaped top surface with a converged valley to facilitate water discharging and form a sturdy and safe construction and has aesthetic appearance.

Abstract: An in-line roller skate, which includes a boot, a front wheel frame and a rear wheel frame respectively pivoted to the sole of the boot by rivets and arranged in a line to hold a respective pair of longitudinally aligned wheels, a brake block selectively fastened to the front wheel frame or rear wheel frame, and two elastic blocks respectively mounted in between a respective bottom trough at the sole of the boot and a respective top trough at one of the wheel frames to absorb shocks and to compensate sideways component of force upon turning of the in-line roller skate.

Abstract: A in-line roller skate having a front wheel frame and a rear wheel frame respectively pivoted to the sole of the boot thereof by rivets and arranged in a line to hold a respective pair of longitudinally aligned wheels, a brake pad selectively fastened to the front wheel frame or rear wheel frame, and two ball socket shells respectively mounted in receiving troughs on the wheel frames, the ball socket shells each holding two steel balls in close contact with the sole of the boot, allowing the wheel frames to flex with sole when the roller skate is tilted to change its skating direction. Flanges and notches are respectively provided at the wheel frames and the sole of the boot to act against the ball socket wheels and to limit the deviating angle of the wheel frames.

Abstract: An automatic fluid stopper and fluid stopper mounting spanner including an automatic fluid stopper installed in a fluid outlet pipe and forced by fluid pressure to close the fluid outlet pipe, and a spanner for turning the automatic fluid stopper into or out of the fluid outlet pipe, wherein the automatic fluid stopper includes a threaded annular mounting base threaded into an inner thread on the fluid outlet pipe, a movable valve inserted through the mounting base and forced by fluid pressure to close the fluid passage, an O-ring mounted around the movable valve for sealing the gap between the outside wall of the movable valve and the inside wall of the mounting base, a stop block coupled to the movable valve, and a spring member mounted around the movable valve and retained between the mounting base and the stop block, the stop block being forced backwards to open the movable valve from the fluid passage through the mounting base when a fluid tap is fastened to the fluid outlet pipe, the movable valve being

Abstract: A form panel quick fastener including a clamping plate having an elongated channel base fixedly fastened to a form panel at an outer side and a through hole disposed in the middle of the elongated channel base and aligned with a through hole of the form panel and a barrel raised from the elongated channel base at an inner side around the through hole of the clamping plate; a screw rod inserted through the through hole of the clamping plate and the through hole of the form panel and having a spiral groove around the periphery; and a ball thrust bearing sleeved onto the screw rod and forced into engagement with the barrel of the clamping plate to hold down the screw rod, the ball thrust bearing including a hexagonal head having a center through hole which receives the screw rod, a tubular flange perpendicularly raised from the hexagon head at one side around said center through hole of the hexagon head, a plurality of spiral holes spaced around the tubular flange at different elevations, and a plurality of stee

Abstract: A faucet including a faucet body defining a ball socket between a water intake port and a water output port, a ball valve mounted in the ball socket and retained between two rigid gasket members, a packing nut fastened to the ball socket to hold down the rigid gasket members and the ball valve, and a handle coupled to the ball valve and moved vertically to turn the ball valve between a first position where the water passage between the water intake port and the water output port is stopped by the ball valve, and a second position where the ball valve imparts a water passage in communication between the water intake port and the water output port.

Abstract: An improved faucet generally comprises a housing, a hot water inlet, a cold water inlet, a hot water outlet, a cold water outlet, a hot water pipe, a cold water pipe, a ball valve, and a spout. The ball valve is provided with water passages such that the hot water outlet and cold water outlet can be suitably aligned with the passages of the ball valve. As a result, when the ball valve is rotated in three dimensions, the temperature of the water as well as the volume on the spout can be readily and conveniently controlled.
