Title: Decolorization of glycosides
Inventor: MCDANIEL ROBERT S JR
IPC: C07H1/06
Filed: 1988-04-18
Granted: 1992-05-26
Abstract: ABSTRACT      This invention relates to a process for reducing the color of a glycoside composition, which process comprises contacting a glycoside composition containing colored humins having conjugated unsaturation with hydrogen or a source of hydrogen under hydrogenation conditions for a sufficient time to decrease the color thereof and there-after recovering the glycoside composition of reduced color.  Hydrogenation may be carried out by use of an alkali metal aluminum hydride such as lithium aluminum hydride or an alkali metal borohydride, such as sodium borohydride, or by means of catalytic hydrogenation, using a catalyst of nickel, platinum or palladium.  The color reduced glycoside is useful as a surfactant for incorporation into a detergent product as a non-ionic surfactant.

Granted: 1993-03-23
Abstract: VAPOR/LIQUID CONTACT DEVICE                        ABSTRACT           An effectively rectangular vapor/liquid contact tray, for utilization in frctionation columns, towers, and the like, for effecting distillation, fractionation, rectifiction, absorption, and refining of various liquid materials such as petroleum, chemical and alcohol solutions.  Provisions are made in the contact tray to reduce the magnitude of vapor-pressure drop between successive contact chambers as well as to provide a positive and more effective vapor/liquid contact.  This result is effected through the employment of a series of mutually spaced parallel baffles.  They are arranged transverse to and submerged in fluid flow, this to take advantage of the advancing liquid's kinetic energy and resulting recirculation zones associated with the baffles and upstream from the outlet weir of the contact tray. Vapor admittance apertures are provided proximate the downstream surfaces of the baffles, through the contact tray, so as to assure positive vapor/liquid contact and to take advantage of low pressure conditions thereat.

Title: Spray boom height adjustment
Inventor: RICHARDSON DELMAR J
IPC: A01M7/00
Filed: 1988-06-10
Granted: 1992-09-08
Abstract: SPRAY BOOM HEIGHT ADJUSTMENT         ABSTRACT OF THE DISCLOSURE          A spray boom  assembly  has  an elongate boom carrier  supported  on walking  axles near  its opposite ends.   Each of the walking axles consists of a pair of parallelogram  linkages  extending  respectively  to  the front and back of the boom carrier.   The parallelogram linkages are linked by an hydraulic cylinder or actuator that can be extended to rotate the parallelogram linkages downwards about their pivotal connections to the boom carrier.   This raises the boom carrier without changing its  orientation.   Thus,  the  boom spray pipe  can  be connected directly to the boom carrier to be raised and lowered with it.  No adjustment of the nozzle orientation is necessary when the boom height is changed.   Another parallelogram linkage arrangement is used to connect the centre  of  the boom carrier to a towing vehicle.   In preferred embodiments,  the boom is made in two parts that are pivotally connected to a common central boom carrier support.   The boom can then be shifted from a field spraying position to a transport position simply by unlatching the boom parts from their spraying positions and driving the towing vehicle forwards.  The walking axles  are pivotally mounted  on  the  boom carrier  for pivotal movement around vertical axis.  This movement is controlled by hydraulic cylinder so that in the transport position,  the walking axles are generally in line with the respective boom sections.

Abstract: ABSTRACT OF THE DISCLOSURE    A novel bowden-cable window lift is provided herein,  for displacing a window pane in a motor vehicle.   The window lift includes  first and second guide rails and first and second drive plates, each such drive plate holding a window pane guided in sliding but geometrically-locking manner at the guide rails.  The drive plates are actuated by a bowden cable displacing the window pane.    The  first  drive  plate is equipped both with  height adjustment means and with independent lateral adjustment means.          The height adjustment means includes an eccentric stud mounted in adjustable and lockable manner to the first drive plate and sliding at the first guide rail and supporting the window pane by means of fastener plates, thereby to set a height of the window pane.  The lateral adjustment means for the lateral displacement of the window pane  includes  an  elongated  slot  in  the  first  drive  plate essentially perpendicular to the direction of displacement of the window pane and within which the eccentric stud glides laterally, thereby  to  allow  a  lateral  displacement  of  the  window  pane transversely to the first drive plate and to the first guide rail guiding  the  first  drive  plate.    To  compensate  for  lack  of parallelism of the guide rails due to the assembly of the window lift, adjustment means are mounted on at least one drive plate, so that the pane can be tipped in its plane.  The adjustment means also allows lateral displacement of the pane relative to the guide rail which guides the drive plate.

Abstract: Low viscosity polymer polyols having high styrene/acrylonitrile ratios and good stability may be achieved by the use of a base polyol having a molecular weight higher than 4000, for example, from 4000 to 6500 and a high molecular weight (HMW) dispersant. The dispersant polyol may range from 1 to 20 wt.%, but may be less than 5 wt.% of the total polyol component of the polymer polyol. The HMW dispersant should have a molecular weight higher than about 6000. Preferably, a semi-batch reactor is used, and a relatively high concentration of the HMW dispersant is initially charged to the reactor, relative to the portion of base polyol. Monomer ratios of styrene to acrylonitrile of 85/15 may be achieved with this method.

Title: Feed forward linear amplifier
Inventor: MYER ROBERT E
IPC: H03F1/32
Filed: 1989-08-24
Granted: 1992-02-04
Abstract: A FEED FORWARD LINEAR AMPLIFIER Abstract A feed forward circuit receives an input signal having at least one carrier therein in a prescribed frequency range. The input signal is applied to a first circuit path having a power amplifier that produces an output signal with a distortion component and to a second circuit path that delays the input signal without distortion. The output signal of the first circuit path is combined with the output signal of the second circuit path to form a signal representative of the distortion component of the first circuit path output signal and the distortion component representative signal is subtracted from the output signal of the first circuit path to cancel the distortion component therein. The prescribed frequency range of the first circuit path output is scanned to detect a carrier signal and the amplitude and phase of the signal in the first circuit path is modified to minimize the magnitude of the detected carrier in the distortion representative signal.
