Patent CA-2091962-A1 (CA)
Title: Clock synchronization system
Inventor: WITSAMAN MARK L
IPC: G04G7/02
Filed: 1993-03-18
Abstract: CLOCK SYNCHRONIZATION SYSTEM       Abstract of the Disclosure A clock synchronization system for synchronizing the performance of a number of clocks (46) so that they run parallel with a reference clock is disclosed. Each clock of this synchronization system includes a counter (52) that indicates the current time and that is sequentially incremented by a counter advance signal applied thereto. A time counter controller (54) both initializes the counter andgenerates the clocking signal that controls the advancement of the counter. The time counter controller further monitors the time indicated by the counter and compares it to a reference-time signal received from a reference clock. Based onthe comparison, the time counter controller selectively reinitializes the counter and adjusts the rate at which the clocking signal is applied to the counter so as to ensure that the counter advances at a rate equal to the rate at which the reference clock advances. In some versions of the invention, the comparison of the reference-time signal to the actual clock counter time is made at a maintenance operation point(58) remote from the clock. In these versions of the invention, the maintenance operation point reports the difference in the two times back to the time countercontroller, which, in turn, makes the appropriate adjustments to the counter and to the clocking signal.

Title: Arc detection system
Inventor: RAGSDALE CHARLES W
IPC: H01T15/00
Filed: 1993-04-14
Abstract: An arc detector for detecting electrical arcs across a break in a line carrying a current in an electrical system. Normally, the line carries current, but when the line is broken, current doesn't flow until an arc occurs across the break.  The arc detector detects the break using a current sensor for measuring the current, a filter for filtering out unwanted frequencies, an amplifier for amplifying the remaining frequencies into a substantially square wave, a counter for counting square wave transitions, and a latch to hold a detection signal at an output node when the counter counts a preset number of square wave transitions without being reset by a reset switch or a periodic oscillator.

Abstract: Un système de radiotéléphone réduit le brouillage par le bruit durant le transfert en rendant silencieux la trajectoire audio d'un récepteur employé dans une station de base cible (135). Après la réception d'un message de demande de transfert, une station de base cible (135) rend silencieuse la trajectoire audio cible et détermine si la trajectoire audio cible a été validée par un signal de brouillage non voulu ayant une tonalité SAT commune. Si la trajectoire audio cible a été validée par un signal de brouillage ayant une tonalité SAT commune, la station de base cible (135) utilisera cette tonalité SAT et l'indication de l'intensité du signal reçu (RSSI) de la transmission voulue de l'abonné (125) pour valider la trajectoire audio cible.  Dès qu'il y a un SAT et un RSSI et que la bonne trajectoire audio cible est validée, l'abonné transmet de la station de base source (130) à la station de base cible (135) sans qu'un tiers subisse une salve sonore désagréable.

Patent CA-2111784-A1 (CA)
Inventor: BOK HENDRIK F
IPC: H01L21/306
Filed: 1993-12-17
Abstract: Cleaning methods and apparatus for removing particulate materials from the surfaces of objects are disclosed.  Megasonic vibrations are utilized to cause a liquid cleaning fluid in a first reservoir to rise above the upper end of the first reservoir, contact the surface of the object to be cleaned and flow over a weir at the upper end of the first reservoir into a second reservoir.  The methods and apparatus are useful to remove small particles, e.g. having a particle size of less than about 1 micron, from flat or curved planar surfaces.  The methods and apparatus can be integrated with subsequent processing steps, e.g. applying thin film coatings, without intermediate handling of the objects.

Title: Door Closer
Inventor: FAYNGERSH ZAKHARY
IPC: E05F3/12
Filed: 1993-12-23
Abstract: A door closer (20) is attachable to a door (24) and includes a cylinder (36) which forms a chamber (44) in which a piston element (50) is movable to move fluid from the chamber to a reservoir (82) upon opening of the door.  After the door (24) has been opened to a position, for example, of ninety-five to one hundred degrees, continued opening of the door causes the fluid to be compressed within the chamber (44) and to be directed only through a back check valve (95) to the reservoir (82).  This results in the development of an adjustable "back check" condition to provide a counterforce to the continued opening of the door.  A passageway (150) is formed in cylinder (36) to allow fluid to flow relatively freely from chamber (44) to reservoir (82) until an inward end (56) of piston element (50) has travelled a prescribed distance "x." This prescribed distance of travel represents the opening of door (24) to ninety-five to one hundred degrees from the door's normally closed position.

Abstract: Provided is a method for removing residual sulfur from a hydrotreated naphtha feedstock (1). The process comprises contacting the naphtha feedstock (1) with a first solid sulfur sorbent (2) comprising a metal on a support to thereby form a first effluent. The effluent is then contacted with a sulfur conversion catalyst in reactor (6) comprising a Group VIII metal in the presence of hydrogen, with the resulting effluent being contacted with a second solid sulfur sorbent (7) containing a Group IA or IIA metal, to thereby lower the sulfur content of the feedstock to less than 10 ppb, and to as low as 1 ppb or less. The feedstock can then the safely used with highly sulfur sensitive zeolitic reforming catalysts without adversely affecting the useful life of the catalyst.
