Abstract: The invention relates to a method of regulating the tar content of precooked anodes intended for the production of aluminum by electrolysis, to an optimum level Bm corresponding to the maximum dry density of the anodes, which utilizes measurements on crude anodes emerging from compaction and without awaiting the results of the cooking process. The method comprises the following repeatedly carrying out of the following sequence of steps: (a) forming a carbonaceous paste containing, by weight, an initial tar content Bo %; (b) forming a number n of anodes from the initial carbonaceous paste, and determining mean dry density by measuring their height H and weight P when they emerge from compaction; (c) forming a further carbonaceous paste containing tar content,  gamma (Bo+xo) % where xo is greater or less than zero; (d) forming a number m of anodes from the second carbonaceous paste and determining the mean dry density gamma (Bo+xo) of the m anodes when they emerge from compaction; (e) comparing  gamma (Bo+xo) with  gamma (Bo), and regulating the tar content of the carbonaceous paste such that: if  gamma (Bo+xo)> gamma (Bo), then Bo+xo is changed by a value x=xo, of the same sign as the preceding increment. If  gamma (Bo+xo) is < gamma (Bo), then Bo+xo is changed by a value x=(-xo).

IPC: H02M7/21

Granted: 1996-03-12
Abstract: In a switching regulator which is operable in response to an input a.c. voltage to produce an output d.c. voltage and which comprises a main transformer having primary and secondary windings for primary and secondary circuits, respectively, the primary circuit is formed by a series connection of the primary winding and a switching transistor selectively turned on and off at a high frequency of, for example, several hundreds of kHz while the secondary circuit comprises a series connection of a saturable reactor, a diode, and an output capacitor connected in parallel to a load.  The saturable reactor exhibits high and low impedances when the diode is put into nonconductive and conductive states, respectively, and serves to reduce a switching loss resulting from interception of a voltage and a current.  A frequency control circuit is connected between the output capacitor and the switching transistor to put the transistor into the on-state and the off-state at the high frequency with a time interval of the off-state kept unchanged and with a time interval of the on-state varied.

Title: Serial data rate detection systems

IPC: H04L25/02
Filed: 1990-09-20
Granted: 1996-03-05
Abstract: A  system  and  method  are  described  for  bit  rate detection in a serial data communication system,  the system  employing  a  data  rate prompt  of  a  pair  of opposite value data bits which follow a series of idle bits.  In a first embodiment a receiving port employs a clocked delay element and a set of data clock rates, each data clock rate being a multiple N of one of a set of established bit transmission rates, ranging from a highest expected bit rate to a  lowest expected bit rate.   The  bit  rate  detection  method  comprises: clocking the delay element at the highest data clock rate, upon the sensing of one of the opposite value data rate prompt bits at the delay element, to step the value of the sensed bit into the delay element.  After a  predetermined number  of  data  clock  pulses  have stepped the value of the sensed bit into the delay element, the system compares the bit value at an input to  the  delay element  and  the bit  value  in  a  bit position  of  the  delay  element.   If  the  comparison indicates an equality of bit values, the delay element is  clocked  at  a  lower  data  clock  rate  until  the comparing step indicates an inequality of bit values. At this point, the bit rate has been determined.      Another embodiment is also described wherein a pair of counters are substituted for the delay element.

Abstract: METHOD OF CLUTCH-TO-CLUTCH CLOSED THROTTLE   DOWNSHIFT IN AN AUTOMATIC TRANSMISSION            ABSTRACT OF THE DISCLOSURE          In an automatic transmission, clutch-to-clutch closed throttle downshifting is controlled by filling the on-coming clutch at a maximum pressure command for a set period while commanding the off-going clutch pressure to a low value and exhausting the off-going clutch before the end of the fill period.  At the end of the fill period the on-coming pressure is set to an initial value and then ramped up until turbine speed is pulled up due to off-going clutch slippage.  Then a closed-loop profile control period starts wherein the slip of the on-coming clutch is measured and controlled to a slip profile.   When synchronization of the on-coming clutch is detected, maximum pressure is commanded.  If the throttle is opened during the downshift, the algorithm reverts to a powered downshift algorithm if the off-going clutch still has pressure or to an open-loop ramp control of the on-coming clutch if the off-going clutch has been exhausted.
