Title: Quick open-quick close full port valve and seals
Inventor: PATACEANO NICOLAS
IPC: F16K5/04
Filed: 1995-01-25
Abstract: The  QUICK  OPEN-QUICK  CLOSE FULL PORT VALVE AND SEALS referred in this disclosure as "QO-QC" is disclosed for use to control the ON/OFF flow of fluids where FAST ACTION is necessary to open or close a large valve for safety reasons or to produce intentionally the phenomenon known  as  the WATERHAMMER. To achieve  the fast action, the "QO-QC" valve divides the full port area into several smaller areas arranged in slots  with  solid section  between the slots on a pair of superimposed concentric discs or domes and/or a pair of concentric cylinders. One disc or dome of the pair of discs or domes and/or one cylinder of the pair of cylinders is  fixed and  the other is rotable. The width of the slots and the solid sections between the slots are selected with such dimensions that by  rotating  a fraction  of  360  degrees turn, the rotable disc or dome and/or rotable cylinder the slots cut into them can be aligned with the  slots  in  the fixed disc or dome and/or cylinder to provide a passage for the fluid to flow through the slots, or can be misaligned, meaning that the slots in the rotable disc or dome and/or cylinder are over the solid  surface  of the  other  disc  or  dome and/or cylinder and the fluid is stopped from flowing. Also the total area of the slots is selected to be equal to the port area required and the valve can be open or closed by a rotation  of a selected number of degrees. There  are several construction features incorporated in the QO-QC valve which makes it to be different from other valves controlling the flow of fluids. The special features of the QO-QC valves and the reason for them are: 1. Because of the  many  port  openings  special  seals, named  in  this disclosure "CUP AND SAUCER TYPE SEALS", have to be provided; the "CUP" of the seals fits around the opening in the rotable disc or dome and/ or  cylinder  and the "SAUCER" is exposed on the inlet side. When the pressure increases, the SAUCER presses the cup inward and the sealing ability over the fixed disc or dome and/or cylinder is  improved. The seals  are  also  flexible  and  when the pressure is reduce over the saucer, caused by the minimum openings for the fluid to pass through, or a "pilot opening", the pressure of the cup over the solid area  is reduced to facilitate the rotation of the rotable parts. 2. Because  it  is  manly designed for large size port areas, the ON/OFF mechanism which turns the rotable disc or  dome  and/or  cylinder  is attached  to the perimeter of the rotable disc or dome or cylinder of the valve, not in their centre; 3. Because of the speed with which the valve closes, it  is  recommended that  the  QO-QC  valve to be used with pressure attenuators or surge suppressors; for this reason, the  valve  housing  is provided  with fittings for mounting pressure attenuators/surge suppressors, such as "Full Energy Release Gate" type.

IPC: G01N27/403
Filed: 1995-06-12
Abstract: A pH measuring electrode includes a probe having two lumens with adjacent first ends. An exposed sensor electrode is secured to the end of one of the lumens. A conductor leads through the first lumen from the sensor electrode for connection to a meter for indicating pH. An electrical reference, for example a fibrous thread extends along the second lumen and is electrically connected to the meter. A porous plug closes the end of the second lumen adjacent the sensor electrode and is electrically connected to the thread. When the thread is saturated with an electrolyte it acts as a salt bridge that can be connected to a reference half cell in the system. The close spacing of the bridge and the sensor electrode is desirable to ensure a quick response and to minimize drift. A chamber may be secured to the tube, with the reference thread extending into the chamber. For use, the chamber and the thread carrying lumen are filled with an electrolytic gel. To provide adequate shelf life, this gel may be injected shortly before use through an access port provided in the chamber for that purpose.

Title: Method for cryptographic authentication of transmitted messages using pseudorandom numbers
Inventor: KOOPMAN PHILIP J JR
IPC: E05B49/00
Filed: 1994-06-29
Abstract: An automobile door lock receiver module (30) and a plurality of keychain fob transmitter units (16) contain identification numbers, secret initial values, and secret feedback masks so as to authenticate encrypted messages from any of the assigned fobs, indicative of commands registered by closing switches on the fob. Each fob is a synchronized with the receiving module by means of a truly random number concatenated with a secret initial value and encrypted, through a linear feedback shift register or other operations. A second secret initial value is encrypted and command bits are exclusive ORed into the low order bit positions; the two encrypted numbers are concatenated and encrypted to form a key word which is transmitted with the fob ID. Synchronization includes decrypting to recover the truly random number and the secret initial value concatenated therewith; the truly random number is compared with previously received random numbers in order to avoid copying of recently transmitted synchronization commands. Successive lock-related commands utilize the number encrypted from the truly random number and the second secret initial value as starting values, employing pseudo random number of encryption iterations. A half-second delay between responses mitigates gaining access through numerical trials. An authenticated panic alarm command operates the headlights and horn of the vehicle but does not alter the synchronization.
