Granted: 1995-09-19
Abstract: A self draining door threshold includes a wedge-shaped silicone check valve in communication with a water reservoir on the interior side.  The check valve is normally closed but will yieldably open in response to water pressure which overcomes the resilience of the silicone material and the air pressure on the top wall of the wedge-shaped passageway.  The check valve functions as a seal against incoming air but will open to allow escape of water as needed.  The silicone material seals around foreign material in the valve making it air tight.  The bottom edge of the door includes moisture resistant material having an upwardly extending portion received in a groove.  The exterior side of the door is also covered with moisture resistant material which has inwardly extending portions received in a vertical groove between abutting panels.  A moisture resistant plate extends along the bottom edge of the door and has downwardly extending portions engaging the weather seal on the threshold on the exterior side and a wood portion of the threshold on the interior side.  The plate directs water from the vertical groove outwardly of the door.

Inventor: OZAKI YASUSHI
IPC: B60C23/00
Filed: 1991-10-28
Granted: 2004-02-24
Abstract: This invention relates to a combination of multiple tires disposed adjacently parallel to each other on a single wheel, respective inner spaces of the multiple tires being communicated with each other by way of an airflow piping. The airflow piping comprises a pneumatic pressure control valve which can be opened ar closed due to an air-leaking candition of the multiple tires. When one of the multiple tires leaks air rapidly, the pneumatic pressure of the other normal tire is also decreased, thereby allowing the driver to notice the puncture. If the former leaks air slowly, its air is supplied by the latter, respective pneumatic pressures are going to become equal, thereby the driver can drive for a certain time and be free from any serious accident that may occur when he is unaware of the puncture.

Title: Method of and circuit for synchronizing data
Inventor: SERACK JAMES ARTHUR
IPC: H04L7/00
Filed: 1991-05-07
Granted: 1996-02-06
Abstract: Asynchronous DS-1 data is byte synchronized and converted to the SONET VT1.5 format by storing the DS-1 data in a store (20) from which it is read in dependence upon a gapped clock signal (40) which is produced by gapping a first gapped clock signal (48) with a ratio of 208/193, which is the ratio of VT SPE bits per frame to DS-1 bits per frame. The first gapped clock sig-nal is produced by gapping a VT1.5 synchronous clock signal (46). A frequency difference between the first gapped clock signal and the asynchronous data rate, multiplied in a frequency multiplier (26) by the ratio of 208/193, is monitored by comparing the counts of modulo-208 counters (84, 86), and, independence upon the monitored frequency difference, the gapping of the syn-chronous clock signal is controlled to achieve positive or negative stuffing and hence to compensate for the frequency difference.
