Abstract:
A shower head assembly includes a first shower head connected to a pipe and a three-way member is connected to the pipe. The three-way member communicates with the pipe, the first shower head and a hose which is connected to a second shower head. A tube is fixedly received in the three-way member and in communication between two paths respectively which are in communication with the first shower head and the hose. A rod is movably inserted in the tube and has two seal members on two ends thereof. A control mechanism is connected to the handle of the second shower head and able to cause the change of water pressure to move the rod such that the user can operate the control mechanism on the handle of the second shower head to control the water flow.
Abstract:
A low profile collector and seal assembly for sealing the open end of a container of an electrochemical cell and providing venting of pressurized gases. An electrochemical cell has a can with a closed bottom end and an open top end, positive and negative electrodes disposed in the can, and a collector and seal assembly disposed in the open top end of the can for closing the open top end of the can. The collector and seal assembly includes a current collector and an annular seal that move relative to each other from a sealed position to a vented position when the internal cell pressure reaches a pressure threshold to vent pressurized gases.
Abstract:
A sectional computer housing includes a plurality of frame posts and a plurality of sectional panels molded using aluminum extrusion. Each of the frame posts is provided with a screw groove at one side thereof and a track at two adjacent sides to the side having the screw groove, respectively. Each of the sectional panel having a turtledove tail-shaped protruding seat at one end thereof and a track at the other end thereof. A plurality of sectional panels is similarly fastened to one another using the protruding seats and the tracks at one side thereof for forming side, top or bottom panels. Outermost protruding seats and the tracks are coordinated with the tracks of the frame posts, and further positioned by longitudinally penetrating screws through the sectional panels and into the screw grooves of the frame posts, thereby assembling into a computer housing having any desired dimensions.
