Abstract: MULTI-FUEL ENGINE CONTROL WITH FUEL CONTROL PARAMETER LOCK            Abstract of the Disclosure A fuel control for an engine using a liquid mixture of two fuels such as gasoline and methanol and derives a fuel control parameter from the output of a fuel composition sensor in a first mode of engine operation and locks the value of the fuel control parameter at the end of the first mode of engine operation for use throughout a second mode of engine operation including closed loop control in response to an air/fuel ratio sensor, as long as the fuel composition does not change more than a predetermined amount during the second mode.  The stable operation of the fuel control in the second mode is thus protected from instabilities introduced by small fluctuations in the fuel composition signal.  In an engine with adaptive learning control, the adaptive learning control mode is reserved for particularly stable modes of engine operation including closed loop stoichiometric control and thus serves well as the second mode of engine operation.

Filed: 1991-03-13
Granted: 1996-02-13
Abstract: Sheet cutting apparatus for severing a rapidly moving web, such as printed paper, into cut sheets in two stages.  In the first stage, spaced cuts are made along a transverse cutting line of the web.  The web is trained between belts which support the cut portions of the web, and the uncut portions of the web are severed to separate sheets.  The sheets are conveyed out of the cutting station and into further apparatus.  Preferably, the belts for supporting the web during the second cutting operation are trained around the knife and anvil rolls which make the cuts.  The purpose of the belts is to prevent the leading edge of the web or a cut sheet from being projected forward of its support, thus tending to become dog-eared or misfed.  The cuts made at the first and second cutting stations can be arranged in various patterns to remedy mis-timing of the respective cutting stations.

IPC: F16C33/20
Filed: 1991-09-27
Granted: 1995-02-07
Abstract: A  track  roller  bearing  having  a floating sleeve between the inner  race  and  outer  race.   The floating sleeve has a self-lubricating  bearing material on its outer surface.  The coeffi-cient  of  friction  of  the  self-lubricating  bearing material increases  as  the  material is worn.  When the self-lubricating bearing  material  coefficient of friction exceeds the coeffici-ent  of  friction  of  the  floating  sleeve  inner surface, the floating  sleeve  will  rotate  with  the outer race until a new unworn  surface  of self-lubricating  bearing  material is pre-sented  to  the load area of the outer race.  This precessing of the  floating sleeve will continue until the entire surface area of   the   self-lubricating   bearing  material  is  worn,  thus extending the track roller bearing life.

Granted: 2002-12-10
Abstract: An electrode is disclosed which is particularly useful as a reference electrode in cathodic protection systems. In any reference electrode or half cell, its continued stability is predominantly dependent on the metal ion concentration around it. In time such ions tend to leach away reducing the stability, effectiveness and life of the electrode. With the present invention such ions in the electrolyte may be replenished by the addition of a concentrated solution of metel salt to a ceramic canister which may include a glaze coating which may have one or more diffusion ports permitting the metal salt solution to leach at a controlled slow rate to the area surrounding the electrode ensuring continued stability and longer effective life for the electrode, The one or more diffusion ports also provide a low resistance current path to or from the lead within to the canister and the surrounding electrolyte.

Title: System and method for image recovery
IPC: H04N9/11
Filed: 1993-03-05
Granted: 1999-03-09
Abstract: A system and method to compensate for effects of a recording  medium  such  as  film  on  image  data  retrieved therefrom.  Red,   green,   blue,   and  infrared  light  is sequentially  transmitted  through  film  having  an  image exposed therein to the system which captures corresponding images. The infrared image maps the location, boundaries and intensities  of  the  media  defects.  The  map  is  employed combinatorially with the other captured images resulting in an image from the film free of the effects of the film defects. In one embodiment the effects of the imperfections are divided out from the red,  green,  blue spectra in an operation  dividing  out  the  infrared  image  data  on a pixel-by-pixel basis. In an alternate embodiment wherein the imperfections substantially prevent transmission of IR light therethrough,   the  IR  image  map  of  the  defects  is nevertheless employed with an automated fill-in algorithm more effectively utilized due to the precision with which the defect boundaries are known.
