Abstract: Stabilisation of a reduced cop-per catalyst by a) passivating the cat-alyst by passing a gas stream that is free of reducing gases and which contains 0.05 to 0.5 % by volume of oxygen and an amount of carbon dioxide at least twice the amount of oxygen through a bed of the cata-lyst until the catalyst is passivated, the proportion of oxygen in said gas stream and the temperature at which it is fed to the bed being such that the temperature of the catalyst does not rise to above 100°C during said pas-sivation step, and then b) increasing the oxygen content of the gas pass-ing through the bed until the oxygen partial pressure corresponds to that of air at atmospheric pressure. The process may be applied to the stabil-isation of fresh reduced catalysts or to the stabilisation of used, e.g. spent catalysts, before discharge thereof from a reactor.

Abstract: Simple and economical embodiments of a drip-stop resistance assembly for caulking guns incorporating a resistance clip, or alternatively, an elastic grommet or constricted spring. The drip-stop assembly may be used with various manually-operated caulking guns including those with metal enclosures and single piece molded plastic open frames, and with various types of plunger shafts including those with a circular or hexagonal cross-section, or ratchet teeth. The drip-stop assembly includes a resistance clip formed of resilient steel wire or the like, and bent or cast in the form of an annular yoke for encircling the plunger shaft and providing frictional resistance against sliding. The resistance clip may be inserted onto the plunger shaft (from above or below the housing) at various positions along the shaft. A back-plate formed by a conventional washer, or angle-bracket is inserted on the plunger shaft and is spaced from the resistance clip for allowing the latter to frictionally slide a short distance. An elastic grommet and constricted spring are also shown as substitutes for the resistance clip. All of the illustrated drip-stop assemblies provide an initial momentary release feature to terminate the bead of caulk upon initial release of the trigger, reduce blow-back, and prevent inadvertent retraction of the plunger shaft. The assemblies are all simple and inexpensive to manufacture, yet highly effective. Its simplicity allows them to be manufactured OEM or retrofit for minimal additional cost.

Title: Clock free two-dimensional barcode and method for printing and reading the same
Inventor: LOPRESTI DANIEL
IPC: G06K7/00
Filed: 1996-12-04
Granted: 2002-02-12
Abstract: Inventive  two-dimensional  barcodes,  each having encoded  digital  information  in  a  bitmap  representing preferably randomized encoded data bits, are printed onto a  printed  medium.   The  bitmap  may  further  include  a plurality  of  block  identifiers,  spaced  a  predetermined number of encoded data bits apart, which are used to make corrections  for  missing  or  added  data  bits  when  the barcode is decoded.   Upon decoding a barcode printed on the printed media, the digital information is scanned and the  number  of  horizontal  and  vertical  edges  in  each respective column and row of the barcode are determined. An edge is determined by selecting a pixel and determining if the two pixels adjacent to the selected pixel are of different  colors.   After all  of the edges are counted, selected  groups  of  columns  and  rows  are  analyzed  to determine  local  minimas   in  the  number  of  counted horizontal and vertical edges in each selected group which provide the column and row center line for each selected group.   Thereafter,  the  binary  data  located  at  the intersection of each column and row center line are read out  to produce  a  signal  representative  of  the  encoded digital information in the printed barcode.

Title: Increasing the capacity of a cellular radio network
Inventor: AALTO RISTO
IPC: H04W16/12
Filed: 1996-10-11
Granted: 2005-03-22
Abstract: The invention relates to a cellular radio network and a method for increasing traffic carrying capacity in a cellular network. The operating frequency spectrum of the cellular network has been divided in such a way that typically both regular frequencies (A, C, F, I) and super-reuse frequencies (S1, S2, S3, S4) are employed in each cell (BTS 1-4). The regular frequencies use a conventional frequency reuse pattern to provide seamless overall coverage (overlay). A very tight frequency reuse pattern is used for the super-reuse frequencies to provide additional capacity (underlay). The cellular network controls the division of traffic into regular and super-reuse frequencies by means of radio resource allocation at the call set-up phase and later on during the call by means of handover procedures. The cellular network monitors continuously the downlink co-channel interference of each super-reuse frequency in the cell separately for each ongoing call.  The call is handed over from a regular frequency to a super-reuse frequency (HO2) when the co-channel interference level on the super-reuse frequency is sufficiently good, When the co-channel interference level on the super-reuse frequency deteriorates, the call is handed over from the super-reuse frequency back to the regular frequency (HO3).

Abstract: The correction system of this invention simulates a power steering leak which the driver can manually adjust or automatically tune to offset vehicle drift and/or pull generated by road crown, wind, vehicle alignment, and tires during straight ahead driving.  The drift and pull correction system taps into the bypass line of a vehicle's power steering system and can be added to the vehicle as an aftermarket device.  For example, the standard rack or power gear, the power steering pump and reservoir and the steering assembly of the power steering system can be used in combination with the addition of correction lines and correction valves of the steering correction system to correct the vehicle's steering system for "straight ahead driving" without operator assistance.    The magnitude of the drift and/or pull is a direct function of the magnitude of the leak and the back (parasitic) pressure in the system.  The correction system bypasses hydraulic fluid to one side of the power steering piston causing the steering system to input a steer angle change to the wheels until the added steering force generated on the vehicle is adequate to balance the forces and moments generated during straight ahead driving.
