US Patent:

20110056579, Mar 10, 2011
Filed:

Sep 4, 2009
Appl. No.:

12/584457
Inventors:

Lincoln Tsai - El Monte CA, US
Benn Tsai - El Monte CA, US
International Classification:

F16L 55/11
F16L 55/18
F16K 17/40
US Classification:

138 89, 138 97, 137 6823, 137 6827
Abstract:

A temporary sealer for pipe repair and construction includes a sealing head, and a breakable film. The sealing head has a tubular shape and a size and shape corresponding to an inner diameter of a pipe. The breakable film is formed at the sealing face of the sealing head, wherein the breakable film forms a water barrier for temporarily restricting a flow of water passing through the sealing head within the pipe when the sealing head is slid into the pipe. The breakable film is inevitably torn apart in responsive to a predetermined water pressure for enabling the water flow passing through the sealing head within the pipe. Therefore, it not only provides a way to efficiently block the water flow when the water pipe needs construction, but also provides an apparatus involving the flow system when the water pipe system is finished with construction.

Appl. No.:

13/815532
Inventors:

Linclon Tsai - El Monte CA, US
Benn Tsai - El Monte CA, US
Jian Hua Cai - Nanchang City, CN
Robert Ponticelli, JR. - Oxnard CA, US
International Classification:

E05B 27/00
E05B 15/00
US Classification:

70491, 70344
Abstract:

A lock includes a lock sleeve, a lock body is disposed in the lock sleeve in a free rotating manner, a lock assembly, an actuating member, and an actuation key. The lock body includes a lock rotor coaxially and rotatably disposed within the lock sleeve, and a lock core coaxially and rotatably disposed within the lock rotor and defined a keyway at the lock core. The lock assembly normally locks the lock core with the lock rotor in such a manner that the lock body is free to rotate within the lock sleeve. The actuation key is slidably inserted into the keyway of the lock core to unlock the key lock unit, wherein when the lock assembly is unlocked by the actuation key, the lock core is rotated within the lock rotor to drive the actuating member to rotate and to longitudinally move for actuating a latch assembly.
