Title: Serving constant bit rate traffic in a broadband data switch
Inventor: PUNJ VIKRAM
IPC: H04L12/56
Filed: 1991-05-30
Abstract: Abstract This invention relates to a method and apparatus for transmitting constant and variable bit rate traffic in a broadband ISDN switch. Data from constant bit rate sources such as television cameras is entered into a group of queues. Each member of the group for queuing data of a different band of bit rates. Data is transmitted from these queues with highest priority from the queue storing data of the highest band of bit rates. If the longest enqueued entity of data in one of the other queues has been enqueued for more than a prespecified period, its priority is increased. Analytic studies have shown that use of three queues for constant bit rate traffic and a fourth queue for variable bit rate traffic allows a high occupancy in the output channels to be maintained with a negligible number of data entities excessively delayed.

Patent CA-2055831-A1 (CA)
IPC: H03H21/00
Filed: 1991-11-19
Abstract: A method of preventing divergent behavior of a recursively adjusted adaptive filter and an adaptive filter to which the method is applied are disclosed.  The adaptive filter is adjusted by alternately carrying out two kinds of corrections during respective correction terms.  In the first correction term, each tap gain in the adaptive filter is corrected through a recursive correction algorithm.  In the second correction term, a new tap gain is produced by multiplying the current tap gain by a constant which is predetermined so as to suppress divergent tendency in recursively corrected values of each tap gain.  Therefore, operations to make recursively corrected values of each tap gain converge and operations to suppress divergent tendencies in the recursively corrected values of each tap gain are executed alternately.

Abstract: Disclosed is a galvanized steel sheet which has a tensile strength of not less than 80 kgf/mm2 and a yield ratio of not more than 60%, and which is applicable to members of an automobile body, particularly those requiring strength.  By appropriately controlling the amounts of C within the range of 0.08-0.20 wt%, Mn within the range of 1.5-3.5 wt%, Al within the range of 0.01-0.1 wt%, P 0.01 wt% or less, S 0.01 wt% or less, and one or both of Ti and Nb within the range of 0.01-0.1 wt%, the structure of the steel sheet is formed into a dual-phase structure having a second phase structure.  The steel sheet is recrystallization-annealed, galvanized while it is maintained at a temperature range near 500°C, and then is cooled.  By controlling the rate of cooling the steel sheet, the second phase structure generated is prevented from hardening more than necessary.          The galvanized high-strength steel sheet has a low yield ratio and excellent stretch-flanging properties.

Abstract: : PROCEDE D'OPTIMISATION DE LA CHARGE D'UNE BATTERIE D'ACCUMULATEURS, ET DISPOSITIFS POUR LA MISE EN OEUVRE DE CE PROCEDE. L'invention concerne un procédé permettant de charger une batterie d'accumulateurs selon un régime de charge pour compenser une décharge vers un circuit extérieur ou selon un régime de maintien pour compenser l'auto-décharge de la batterie. Il consiste à : - déterminer (23) la capacité de la batterie à la charge, en fonction de la température (Tb) de la batterie, cette capacité à la charge se réduisant et devenant inférieure à la capacité de référence lorsque la température augmente pendant une période de charge; - calculer (25) le bilan de la quantité d'électricité reçue par la batterie et de la quantité fournie par la batterie à un circuit extérieur; - décider (31) de passer du régime de maintien au régime de charge, chaque fois que le bilan est inférieur à la capacité à la charge. Ainsi la charge d'une batterie peut être amenés à sa valeur optimale, en plusieurs périodes de charge séparées par des périodes de régime de maintien, si les conditions de la batterie, notamment sa température, améliorent sa capacité à la charge. Le procédé est autoadaptif aux caractéristiques de charge de la batterie sans pour autant provoquer une surcharge systématique à la fin de chaque cycle de charge. Application aux alimentations secourues par des batteries d'accumulateurs. FIGURE A PUBLIER : Figure 2.

Title: Telescoping frostproofing sleeve expandable to frost depths of area
Inventor: BERGEY MICHAEL J
IPC: F16L25/10
Filed: 1992-03-18
Abstract: Abstract of the disclosure A sleeve covering to surround a vent pipe which is to be buried and inserted into and connected to a T-fitting trap of a sanitary sewer system is described which sleeve covering will prevent the frost or frozen earth from heaving the pipe which it surrounds.  The repeating sleeve covering is basically a number ofhollow vertical sections or  coupling members, generally cylindrical in shape, whose inside diameter of the bottom portion of each is slightly greater than thepipe which it surrounds.  Vertical movement of the sleeve sections or coupling members (one or more or all) is possible without causing any vertical movement of the pipe that the sections surround. Also, because of the particular exteriorshape (frusto-conical) of the top portion of each section, the exterior forces exerted upon same by the earth when it freezes actually tends to force the sleeve sections downward rather than upward.  Also, because the sleeve covering is madeup of a number of coupling members, the heaving forces exerted by the earth can he restricted to act upon an individual sleeve section and/or to act upon only alimited few such sleeve sections rather than upon the entire sleeve covering. The invention also includes a novel and greatly improved method of connecting the vent pipe to the T-fitting trap of the sewer system.
