Title: Process for preparing glyoxylic acid/dialkyl aminomethylphosphonate mixtures
Inventor: ANTON DAVID LEROY
IPC: C12P13/04
Filed: 1994-05-20
Abstract: The invention provides a process for producing mixtures of glyoxylate and a dialkyl aminomethylphosphonate and the subsequent production of N-(phosphonomethyl)glycine, also known as glyphosate. The process comprises preparing in situ a mixture of glyoxylate and a dialkyl aminomethylphosphonate (DEAMPA) by enzymatically reacting glycolic acid (glycolate) and oxygen in an aqueous solution in the presence of a dialkyl aminomethylphosphonate and catalysts consisting of glycolate oxidase and catalase. The resulting mixture can be hydrogenated and then subjected to hydrolysis to produce N-(phosphonomethyl)glycine, a post-emergent phytotoxicant and herbicide.

Title: Flexible meshing type gear device with a passing tooth profile
Inventor: ISHIKAWA SHOICHI
IPC: F16H1/32
Filed: 1995-04-14
Abstract: A meshing type gear device having improved strength and wear resistance and more particularly improved tooth surface wear resistance. Inca meshing type gear device (1), spur gears are used for both a rigid internal gear (2) and a flexible external gear (3), and the number of teeth of the flexible gear (3) is made greater by two than that of the rigid internal gear (2). The tooth profile of the flexible external gear (3) is made convex and the shape thereof is that of a curve AC obtained by subjecting a gear tooth portion (curve portion between A and B), which, at the moving path L that the external gear describes relative to the internal gear, as determined by rack approximation, is convex relative to the internal gear, to similarity transformation at a reduction ratio using the limiting point A of the contact between the two gears on the path as the origin, while the tooth profile of the rigid internal gear is made concave and the shape thereof is that of a curve AD obtained by subjecting the same portion convex relative to the internal gear at the moving path to similarity transformation at an enlargement ratio (1 + .lambda.) using the limiting point A as the origin, whereby the meshing of the two gears maintains continuous contact and is of the passing type. With this configuration, it is possible to greatly enhance the retention of a lubricating oil film between the tooth surfaces and to markedly improve the permissible delivered torque of the flexible meshing type gear device based on tooth surface wear.

Title: Optical disc system
Inventor: CRUPPER RANDOLPH SCOTT
IPC: G11B7/125
Filed: 1996-01-18
Abstract: An optical disc system including a focusing mechanism and a tracking mechanism, wherein the mechanisms are controlled by feedback loops having electronic circuits for generating a servo error signals. The error signals are communicated in the feedback loop for effecting corrections of the focusing mechanism and the tracking mechanism. The optical disc system is provided with digital lead/lag compensation circuit assembly including a servo loop having servo loop transfer function and an error signal. The circuit assembly includes a motor or actuator having a mechanical resonance frequency being less than a predetermined sampling frequency and a compensation circuit for stabilizing the servo loop. The error signal of the servo loop is sampled at the pre-determined sampling frequency. Normalization of the error signals to the information signal occurs during sampling. The compensation circuit has a compensation transfer function including a single lead and a complex lag for producing a notch filter with a notch. The compensation transfer function is formulated so that the notch occurs at approximately one half the predetermined sampling frequency thereby reducing amplitude of the mechanical resonance frequency in the servo loop transfer function. The optical disc system also includes a mechanical isolator for vibration isolation and accommodation of thermal expansion, an oscillator with a tank circuit having an increased resistance, an improved focus capture system, and means for identifying blank sectors in a storage medium.

Title: Treatment of filtrates in peroxide bleaching of pulp
Inventor: STROMBERG C BERTIL
IPC: D21C9/02
Filed: 1996-02-28
Abstract: Cellulose (paper) pulp is bleached by first washing it in a first washing stage using a first wash liquid, passing the pulp from the first washing stage to a peroxide bleaching stage (either unpressurized or at superatmospheric pressure), after the peroxide bleaching stage washing the cellulose pulp in a second washing stage using a second wash liquid and producing a filtrate, and then treating the filtrate and bringing the filtrate to the first washing stage to be used as the wash liquid in it.  The filtrate is treated by bringing it into intimate contact with an oxidizing gas to oxidize contaminants in it.  The method typically includes an ozone bleaching stage either before or after the peroxide stage, in which ozone containing gas is used to bleach the pulp and produces an off gas containing residual amounts of ozone (typically in an oxygen carrier gas).  This off gas with residual ozone (which may be supplemented by ozone from a low cost ozone generator) is preferably used as the oxidizing gas for the filtrate, and can be used to remove odors from other pulp mill fluid streams.  The filtrate may be treated in a vertical tank having a gas sparger at the bottom in which case the oxidizing gas is introduced into the vertical tank through the gas sparger, and the tank is maintained at either atmospheric or superatmospheric pressure.  Alternatively a gas scrubber, or other conventional gas-liquid contactor, can be used to treat the filtrate.

Patent CA-2176481-A1 (CA)
Inventor: ABOU-RACHED ROGER GEORGES
IPC: E04C5/18
Filed: 1994-01-07
Abstract: An earthquake, fire and wind resistant pre-fabricated building panel comprises aplurality of frame members (150, 152-155). The frame members are connected together to form a frame lying in a frame plane, the frame defining a perimeter of the panel, the perimeter bounding an interior portion of the panel. At least some of the frame members are biased inwardly, generally in the frame panel, towards the interior portion of the panel. A first solidified castable substance (270) is cast in the interior portion of the frame, between the frame members. A three-dimensional structure such as a house is formed by connecting the panels together. The connections absorb and distribute seismic forces to the entire three-dimensional structure and the biased frame members act to absorb residual seismic forces reaching the individual panels. The castable substance and biased frame members permit the panel to withstand both positive and negative loading and render the panel fire resistant.
Patent CA-2177428-A1 (CA)
Inventor: MARSDEN JAMES GARFIELD
IPC: F27D1/16
Filed: 1996-05-27
Abstract: The present invention discloses novel nitrogen-hydrogen based atmospheres for sintering steel components in continuous furnaces with consistent quality and properties while prolonging the life of the wire mesh belts, reducing maintenance costs, and improving furnace productivity. Specifically, it discloses the use of a controlled amount of an oxidizing agent such as moisture, carbon dioxide, nitrous oxide, or mixtures thereof along with nitrogen-hydrogen atmospheres to (1) sinter steel components with consistent quality and properties, (2) prolong life of wire mesh belts, (3) reduce downtime and maintenance costs, and (4) reduce the formation of soot in the furnace. The use of a controlled amount of an oxidizing agent has been unexpectedly found to form a protective and adherent oxide layer on the belt material, eliminate complete reduction of the belt material in the heating zone of the furnace, and prevent sticking of sintered components on the belt material, all of which are responsible for significantly increasing belt life by reducing (1) erosion of the belt material caused by cyclic oxidation in the preheating zone of the furnace or in the ambient atmosphere outside the furnace and reduction in the high heating zone of the furnace, (2) embrittlement of belt material caused by the formation of metal carbides and nitrides, and (3) degradation of belt material by splashing of foreign material from parts being processed onto the belt. The amount of an oxidizing agent added to the nitrogen-hydrogen atmospheres to pre-condition belt material prior to its use for sintering and to sinter steel components is controlled in such a way that atmospheres become oxidizing to the belt material but reducing to steel components being sintered, specifically in the high heating and cooling zones of continuous furnaces.
