Inventor: BUELL KENNETH BARCLAY
IPC: A61F13/15
Filed: 1992-01-28
Granted: 1997-01-28
Abstract: A "zero strain" stretch laminate web exhibiting a non-uniform degree of elasticity, as measured in the direction of elasticization at various points along an axis oriented substantially perpendicular to the direction of elasticization. Improved method and ap-paratus for non-uniformly stretching "zero strain" stretch laminate webs to impart elasti-city thereto in the direction of stretching, at least up to the point of initial stretching are also disclosed. The "zero strain" stretch laminate material (i) is formed of at least two plies of material which are either intermittently or substantially continuously secured to one another along at least a portion of their coextensive surfaces while in a substantially untensioned ("zero strain") condition. One of the plies (4a) is stretchable and elastomer-ic, while the second ply (5, 6) is elongatable, but not necessarily elastomeric. The second ply will, upon stretching of the laminate, be at least to a degree permanently elongated so that, upon release of the applied tensile forces, it will not return to its original undistort-ed configuration. This results in z-direction bulking of the laminate web when the appli-ed tension is released as well as elastic extensibility in the direction of initial stretching, at least up to the point of initial stretching. In a particularly preferred embodiment of the present invention, the mechanical stretching of said laminate web is carried out by pass-ing said laminate web between at least one pair of meshing corrugated rolls (21, 25), the degree of meshing between said corrugated rolls being non-uniform about the periphery of sa?rolls, whereby said laminate web is subjected to non-uniform incremental stretch-ing as it passes therebetween to produce a varying degree of elasticity in the resultant web.

Title: Modification of lignin synthesis in plants
Inventor: BOUDET ALAIN M
IPC: C12N15/53
Filed: 1992-04-27
Granted: 2002-10-15
Abstract: The synthesis of lignin by plants is controlled by transformation of the plant genome with a recombinant gene construct which contains the gene specifying an enzyme critical to the synthesis of a lignin precursor, which gene may be in antisense orien-tation so that it is transcribed to mRNA having a sequence complementary to the equivalent mRNA transcribed from the endoge-nous gene thus leading to suppression of lignin synthesis. If the recombinant gene has the lignin enzyme gene in normal, or "sense" orientation, increased production of the enzyme may occur when the insert is the full length DNA but suppression may occur if only a partial sequence is employed.

Granted: 1997-03-11
Abstract: A  medical ventilator is provided for providing continuous, closed-loop control of the pressure of gas within a patient's  mouth  or  respiratory  tract  in accordance with any selected pressure input waveform. The medical ventilator comprises an adaptive, feedback controller which provides independent control of the inspiratory and expiratory branches of the ventilator, while  continuously  controlling  mouth  pressure.  The digital coefficients of the controller are updated to adjust for variations in the resistance of the patient's respiratory tract resulting from the magnitude of flow of inspiratory gas into the tract and patient-to-patient differences.  Pressure  in  the  expiratory  branch  is controlled by controlling, through a pressure-regulating valve,  the magnitude  of back pressure  applied  to  a diaphragm  valve.  A  venturi  provides  a  reference pressure for the pressure-regulating valve below that of the surrounding atmosphere to enable application  of a negative back pressure to the diaphragm valve.

Title: Double drum waste water screen
Inventor: ZITTEL DAVID R
IPC: B01D33/11
Filed: 1994-09-08
Granted: 2000-02-01
Abstract: An interior wedge wire drum screen is mounted wholly within an exterior drum screen of narrower wedge wire spacing, and both are mounted to a frame and caused to rotate about a common central axis. One and of the outer drum is open and the other is closed by a disc-shaped drum head. The inner drum has an open end which is spaced inward of the open end of the outer drum. The waste water is presented to the surface of the inner drum screen by a waste water infeed which employs a vertical column.  The column extends upwardly of an inlet and has a gradually increasing cross-section for reducing the flaw of velocity of the waste water. A horizontal trough extends along the axis defined by the drums and communicates between the top of the column and a tray. The edges of the tray terminate in weirs which are parallel to the sides of the inner drum. Water flows in a smooth sheet over a weir to impact the sides of the inner screen with low velocity. As the drums rotate the accumulating filtrate is moved by a spiral auger which progresses the filtered material to the open ends of the drums. The material from the inner drum falls to the surface of the outer drum, and is progressed to a waste collection trough.
