Granted: 1993-04-01
Abstract: A coupling system for pipes is described, which prevents pipes which are not associated with one another being connected, in that a plug nipple (1-3, 1-6) which is connected to a pipe and a coupling (2-3, 2-6) which is connected to the other pipe are provided, the two of which, when joined together, have a defined overall length which corresponds, for example, precisely to the distance between two holding parts (4, 5) of a holder (3) into which the joined-together coupling elements are inserted with the pipes which are connected via them. All the plug nipples and coupling parts in each case have different individual lengths, so that the overall length of coupling elements which are joined together but which are not associated with one another differs from the predetermined length, as a result of which, for example, insertion of the coupling elements which are connected to one another into the holder becomes impossible.

Title: Arc prevention circuit for a mechanical switch
Inventor: NISHIHIRA THOMAS S
IPC: H02J3/00
Filed: 1997-11-04
Granted: 2001-04-21
Abstract: A device for controlling a switching relay to deliver power to a load. The switching relay selectively couples a hot leg of a utility power supply to the load. The load is coupled to a neutral wire of the utility power supply. The device includes a sensor for detecting whether an area is occupied. If the sensor indicates that the area is occupied and the load is powered off, the device monitors the line voltage for a zero crossing. Upon detecting a zero crossing, an amount of time to a subsequent zero crossing is measured and stored. Then, the device waits the amount of time between zero crossings, less a delay time for closing the contacts of the relay, and initiates a closing of the contacts of the relay.  Similarly, when the sensor detects that the area has not been occupied for a predetermined amount of time and the load is powered on, the line voltage is monitored for a zero crossing and a time to a subsequent zero crossing is measured and stored. Then, the device waits the amount of time between zero crossings, less a delay time for opening the contacts of the relay, and initiates an opening of the contacts of the relay. Accordingly, when the relay contacts actually close or open, the line voltage is at the ground level. Therefore, even if the load has a high in-rush current or high kick-back power, the relay contacts are not likely to be damaged.

Title: Improved process for laser welding car use galvanized steel plates
Inventor: CHEN JIUN
IPC: B23K26/00
Filed: 1998-03-17
Granted: 2000-06-01
Abstract: This invention relates to an improved process for laser welding car use galvanized steel plates using high-power laser. Generally, while laser welding surface-treated, corrosion-resistant steel plates, such as laser welding galvanized steel plates, it is crucial to control the butt gap between steel plates of different thickness, to tightly join the butt faces, and to control the trimming angle between the trimming faces of the steel plates, or will otherwise result in sunk weld path. This invention controls process parameter of laser welding, including pre-determined welding gap, laser incidence angle, laser focal poing location, welding power, and the welding speed, and uses laser energy to melt the molten metal formed from the thicker steel plate, so as to fill the butt gap between two steel plates.  The weld path obtained is wider and a smooth transition is formed between two plates of different thickness. Such a process not only reduces the number of the air holes in the weld path, but also reduces the limitations required in trimming the steel plates.
