IPC: C01F7/473
Filed: 1991-06-24
Abstract: ABSTRACT    The invention relates to crystal growth modification and more particularly, to modification of crystal growth during precipitation of alumina in the Bayer process.  Aluminous ores are digested in a caustic liquor to extract alumina values.  The liquor is subsequently clarified to remove caustic insoluble materials and alumina crystals precipitated from the clarified liquor.  In one aspect of the invention, an effective amount of a polysaccharide or a polysaccharide graft copolymer is added to the liquor after the clarification step and prior to or during the precipitation step.

Title: Piston and process for achieving controlled ignition
Inventor: FAILLA CHARLES C
IPC: F02B1/04
Filed: 1990-01-23
Abstract: A piston for an engine is provided with a reaction chamber (44) communicating with a recessed area (42) of the piston through a restricted continuous slot orifice (46). The fuel undergoes a controlled, cold flame reaction process while in intimate contact with the crown portion (54) of the piston (14). The reaction produces enough radicals to seed subsequent fuel charges to properly condition the charge. The orifice (46) ensures that outward flow of radicals from the reaction chamber is controlled to the extent that they will be maintained in the combustion chamber following an exhaust event of the combustion cycle so they will be available during a subsequent compression stroke of the piston for seeding the subsequent charge. The radical population in the subsequent charge conditions the charge to obtain dependable ignition in a compression ignition engine as well as knock free combustion at relatively lean air to fuel ratios in a spark ignited engine.

Title: Zero-sync-time apparatus for encoding and decoding
Inventor: HOPPES RONALD R
IPC: H04L12/46
Filed: 1991-08-12
Abstract: In a digital data transmission system for transmitting a serial digital data stream between a first unit and a second unit connected to a first and second bus, respectively, a first apparatus interfaces the first bus to a transmission medium and a second apparatus interface the second bus to the transmission medium. The first and second unit and the first and second apparatus each have their own clock circuit. The first and second apparatus each comprise an encoder which outputs the serial digital data stream onto the transmission medium corresponding to serial data received from the first bus during a transmission period of the first bus. The encoder outputs the serial digital data stream onto the transmission medium in a predetermined format during a quiescent period of the first bus. A phase relationship of the serial data and the serial digital data stream outputted at the start of transmission between the quiescent period and the transmission period is established in a single bit time. A decoder decodes the serial digital data stream inputted from the transmission medium to determine the bit value of information. A receiver/transmitter couples the signals between the first bus and the apparatus.

Title: Multi-level sulfide content pulping
Inventor: RYHAM ROLF
IPC: D21C3/02
Filed: 1992-05-22
Abstract: Paper pulp (e.g. kraft pulp or sulfite pulp) is produced utilizing at least two different supplies of cooking liquor (e. g. white liquor), having different percentages of lignin reaction enhancing or carbohydrate degradation slowing chemicals (e.g. one having low sulfide content, and the other high sulfide content). The high sulfide content supply is typically used to impregnate the pulp, while the second supply is used in other cooking stages (whether co-current or countercurrent). At least 60% of the sulfide of the cooking chemicals may be prodded in the first supply. Some of the sulfide in the first supply is desirably provided in the form of polysulfide or elemental sulfur. When about 2% polysulfide on wood is utilized yield is significantly increased. Utilizing multiple chemical (e. g. sulfide) content supplies results in an optimum viscosity/kappa ratio and/or pulp strength properties for the pulp produced.

Title: Method of correcting lateral force variations in a pneumatic tire
Inventor: WILD JOYCE R
IPC: G01M17/02
Filed: 1993-01-28
Abstract: ABSTRACT      A method is provided for correcting excessive lateral force variations in a pneumatic tire.  The method includes the steps of indexing the tire tread into a series of circumferential  increments;  and obtaining a  series  of lateral force measurements corresponding to this series of circumferential increments.  The maximum value max(1) of the lateral force measurements in a first direction and the maximum value max(2) of the lateral force measurements in a second opposite direction are then determined. This determination is followed by a comparison of each of the lateral  force  measurements  with  the  max(2)  value  to determine if it exceeds an acceptable deviation and an independent  comparison  of  each  of  the  lateral  force measurements with the max(1)  value to determine if it exceeds the acceptable deviation. The acceptable deviation may  be  a  preset  constant  value.    Alternatively,  the acceptable deviation may be determined by calculating a PtP value which represents the difference between the max(1) value and the max(2) value; and calculating the acceptable deviation  based  on  the magnitude  of  this  PtP value. Material is removed from a first shoulder region of each increment in which the corresponding force measurement exceeds the acceptable deviation when compared to the max(2)  value;  and material  is  removed  from  a  second shoulder  region  of  each  increment  in  which  the corresponding  lateral  force  measurement  exceeds  the acceptable deviation when compared to the max(1).   447\18894612.20A
