Title: Aldehyde production from alkylaromatics using molten nitrate salt catalyst
Inventor: PENNINGTON B TIMOTHY
IPC: C07C45/36
Filed: 1989-09-29
Granted: 1993-07-20
Abstract: ABSTRACT     The invention is concerned with a process for producing aldehydes and, more specifically a process employing a vapor phase reaction in the presence of a molten nitrate salt catalyst.  An alkylaromatic compound having from 7 to 22 carbon atomes per molecule, or mixture thereof, is reacted with an oxygen-containing gas, the alkylaromatic compound and the oxygen-containing gas being gaseous reactants.  The reaction is carried out by contacting the gaseous reactants with a bath, stream, spray or mist of at least one molten nitrate salt catalyst, the catalyst being present in an amount sufficient to absorb any heat generated during the reaction while maintaining an essentially constant reaction temperature, the reaction being conducted at a reaction temperature of between about 135°C and about 600°C and a reaction pressure of between about 1 and about 50 atmospheres to produce the aldehyde or mixture of aldehydes.

Abstract: An improved, solvent-free, two-stage transesterification process for preparing, from a polyol and fatty acid esters of an easily removable alcohol highly esterified polyol fatty acid polyesters having reduced levels of difatty ketones and beta-ketoesters is disclosed. These reduced levels of difatty ketones/beta-ketoesters are achieved by controlling the level of generated alcohol in the liquid phase of the reaction mixture and heating the reaction mixture to certain temperatures during the second stage of this improved process. Other optional reaction conditions, such as keeping the molar ratio of fatty acid esters to polyol within a specified range and reducing the level of basic catalyst, can also be used during the second stage reaction to further reduce the level of difatty ketones and/or beta-ketoesters.

Abstract: A method of highly efficiently separating preferably low contents of gaseous mercury from a gas mixture, where the gas mixture is caused to contact a solid sorbent consisting of powdered calcium hydroxide, which in an atmosphere containing hydrogen chloride is to a certain part converted to calcium chloride. The temperature of the gas mixture is between 350 DEG  K. and 550 DEG  K. The contact between the gas and the sorbent preferably takes place in a fluidized bed, whereafter the sorbent is separated in a dust separator. The method is suitable for use at the separation of mercury occurring in flue gases, for example from refuse incinerators or in mercury-containing gases from process industries. At experiments with flue gas from a refuse incinerator the mercury content was reduced from 200 to 5  mu g of gaseous mercury/cubic meter flue gas.

Title: Method and means of shortening memory fetch time
Inventor: CHAN SHIU K
IPC: G06F12/06
Filed: 1991-06-07
Granted: 1996-04-16
Abstract: Speeds  up  computer  memory  system  operations  by providing a memory fetch cycle that is shorter than the memory store cycle.  To do this, the invention changes the timing of the recovery part of the fetch operation in the semiconductor memory chips of the memory.  Each chip has at least one dynamic random access memory array (DRAM) and a small high speed cache memory (SRAM) on the chip.  The system memory controller recognizes the fetch or store state  of  a  memory  request  in  generating  a  DRAM subrow-address timing signal  (RAS)  and a cache address timing  signal  (CAS)  for  enabling  the  accessing  and addressing of bits in the SRAM and the recovery in the DRAM.  The invention controls RAS to start DRAM recovery for a fetch cycle near the start of fetching of data from the SRAMs on the chips, but controls RAS to not start DRAM recovery for a store cycle until SRAM data storing is done.   The  clocks  on the  chips  contain circuits  that enable  fetching  of  data  from  the  SRAMs  during  DRAM recovery,  but that prevent DRAM recovery from starting until data storing in the SRAMs is complete.
