Abstract: A fluidized process which comprises contacting a hydrocarbon feedstock with a fluidized particulate solid in a contacting zone wherein carbonaceous deposits accumulate on the solid and the solid becomes spent and wherein the carbonaceous deposits are burned from the spent solid to produce a regenerated solid; removing a stream of the fluidized spent solid and entrained hydrocarbons from the contacting zone; introducing the fluidized spent solid/entrained hydrocarbon stream and a stream of hot regenerated solid into a lower portion of a zone; introducing a stream of a fluid stripping medium, e.g, water and/or steam into the lower portion of the stripping zone to contact the spent sold therein; passing a stream of the spent solid mixed with the stripping medium and the hot regenerated solid upwardly in the stripping zone to an upper portion thereof under dilute phase stripping conditions; separating the spent solid from the hydrocarbons and stripping medium in a separation zone connected to the upper portion of the stripping zone; passing a fluidized stream of separated solid from the separation zone to the regeneration zone wherein said carbonaceous deposits are burned therefrom to produce a regenerated solid for return to the reaction zone; removing a stream containing vaporized separated hydrocarbons and stripping medium from the separation zone; separating the vaporized separated stripping medium from the hydrocarbons; recycling the separated stripping medium to the stripping zone.  The process also contemplates introducing the medium into a lower portion of a dilute phase zone to cool the solid.

Inventor: VOLLENWEIDER JUERG
IPC: B65B9/02
Filed: 1996-04-11
Abstract: By using the method according to the invention sample bags (12) are produced from webs (1') of film material by forming longitudinal seams (6') and transverse seams (6) and by filling the bags between forming successive transverse seams (6). The sample bags made with the inventive method can, compared to corresponding bags produced according to the state of the art, be further processed more safely and with less problems in automatic processes even at high processing speeds. Such an automatic process is e.g. inserting sample bags into or attaching them to printed products. The conditioning of the sample bags for such further processing substantially consists of a stabilizing of form and is achieved in that the sample bags are subjected to an additional forming step and/or in that they are equipped with an additional forming element. The sample bags produced according to the invention can be handled individually or as a web much more easily because they have a defined form which does not substantially change when being handled. They can be stacked to stacks or bundles, be gripped individually and be further processed with known means.

Title: Arrangement for Queuing a Call to the Best Split
Inventor: FLOCKHART ANDREW DEREK
IPC: H04Q3/545
Filed: 1996-08-14
Abstract: A call-center ACD switch (105) is modified to respond to an arriving call by determining, for those splits (110-111, 106-109) that could handle the call, the present values of a parameter that defines what is a best split for handling the call, determining from those present values which one of the splits is the best split for handling the call, and then enqueuing the call in the call queue of the best split. Alternatively, the call-center ACD switch is modified to respond to a call that overflows the call queue (130) of its primary agent split (110) by determining which one of the backup splits (111, 106-109) in which call center (143-145) is the best backup split for the call, and enqueuing the call in the call queue of the best backup split. Any desirable criterion or criteria may be used to determine which split is best for the call. A preferred criterion is queue waiting time: the best split is the one whose call queue offers the shortest in-queue waiting time. The waiting time may be either the real estimated waiting time (EWT), or the EWT weighted for other factors (WEWT) -- the cost of facilities involved in connecting the call to the split's corresponding queue, for example, or a desire to retain the call for the preferred split unless its waiting time can be improved elsewhere by a predetermined minimum amount. A queuing control function (207) is implemented as an an administratively-programmable executable script, and it directs the ACD switch to obtain, for each call, the EWTs of the splits, to weight these EWTs in order to obtain the corresponding WEWTs, to compare the WEWTs with each other in order to find the split with the shortest WEWT (the best backup split), and then to enqueue the call in the queue of this best split.

Abstract: Herein disclosed are a method and an apparatus for supplying an electrical energy to a pair of discharge electrodes  spaced  apart  from  each  other  to  cause  an electric  discharge  in  a  gap  between  the  discharge electrodes.  There  are  firstly  provided  an  alternating voltage  generator  for  generating,  as  the  electrical energy, an alternating voltage having a frequency, and a capacitor  connected  to  the  discharge  electrodes  in series.  The alternating voltage generator has a series resonant  frequency.  The  alternating  voltage  of  the alternating voltage generator is applied to the discharge electrodes through the capacitor.  The frequency of the alternating voltage is set approximately to the series resonant frequency of the alternating voltage generator to cause a dielectric breakdown in and allow an electric discharge current to flow through the gap between the discharge electrodes.   Alternatively,  the  frequency of the alternating voltage may be approximated to the series resonant frequency of the alternating voltage generator, for  example,  from a  frequency higher than  the  series resonant frequency.
