Granted: 1996-07-09
Abstract: A high density surface emitting semiconductor LED array comprises disordered regions extending through a second confinement layer, an active layer and partially extending through a first confinement layer to define light emitting areas therebetween the disordered regions. Individual contacts on the second confinement layer aligned with each emitting area inject current through the layers to a contact on a substrate causing emission of light from the active layer through the surface of the exposed first confinement layer in the substrate. The second confinement layer can be replaced with a DBR to form an enhanced LED array. Both confinement layers can be replaced with DBRs to form a laser array. A refractive semiconductor layer, fresnel lenses or a micro lens array can be used to optically modify the surface emitted light.

Title: Process for removing condensable components from gas streams
Inventor: WIJMANS JOHANNES G
IPC: B01D53/22
Filed: 1990-11-07
Granted: 2000-08-08
Abstract: A process for treating a gas stream to remove or recover a condensable component. The process involves a condensation step and a membrane concentration step. The condensation step may be followed by the membrane step, or vice versa. The process can be designed to yield only two product streams: one, the condensed liquid (5), ready for use, reuse of discard, and two, a residue gas stream (8), which in most cases will be clean enough for direct discharge or reuse. This result is achieved by recycling other streams within the process. Recovery of 90 % or more of the condensable component can be achieved. The process offers substantial energy savings compared with condensation alone.

IPC: F16K15/03
Filed: 1992-07-22
Granted: 1994-11-01
Abstract: A top-entry check valve has a valve chamber containing a seat, cage, disc and utilizes a spring retainer to prevent movement of the seat, cage and disc in the downstream direction.  A removable bonnet covers an access opening the valve chamber.  The seat and cage are a unitary structure for ease in replacing the seat and cage.  An annular shoulder in the valve body prevents movement of the seat, cage and disc in the upstream direction.   The spring retainer is secured in the valve body by engagement with a lug in the valve body, the unitary seat and cage, the access opening in the valve body and the bonnet.  Removal of the bonnet allows access to the valve chamber for replacement of the seat, cage, disc or spring retainer.

Abstract: An improvement over a prior art mobile hydraulic conveyor apparatus which is mounted on the rear end of a truck for both vertical and lateral pivoting, as well as vertical storage for transport to different locations. The apparatus is moved vertically by a block and tackle arrangement under hydraulic control. Lateral pivoting is achieved by activation of a pair of hydraulic cylinders which act on the conveyor apparatus to shift the apparatus laterally about a pivot axis extending centrally through a turret connected to the conveyor apparatus and mounted on a turret holder which in turn is pivotally mounted on the rear end of the truck. The turret holder includes a c-ring which is mounted in a circumferential groove formed on the turret. The conveyor apparatus includes two pivotally connected trays which support a hydraulically driven belt which transports material dispersed from the truck to a selected location. During transport the trays may be pivoted upwardly in a folded position by providing hydraulic power to the block and tackle arrangement. The rear end of the truck includes a slidable panel which is hydraulically lifted to enable material carried by the truck to flow onto the conveyor apparatus. The trays may be moved from a folded position to an unfolded position by links connected to the trays actuated by at least one hydraulic cylinder connected to one of the trays and to the links.

Title: Truncated tissue factor and fviia or fvii activator for blood coagulation
Inventor: MORRISSEY JAMES H
IPC: G01N33/68
Filed: 1993-05-12
Granted: 2008-01-15
Abstract: It has been discovered that it is possible to administer truncated tissue factor, not having the transmembrane region, (tTF) in combination with factor VIIa (FVIIa) or an activator of endogenous factor VII to treat bleeding disorders such as those resulting from hemophilia or cirrhosis of the liver. The tTF is administered to produce up to 10 pg tTF/ml of plasma. The FVIIa or FVII activator is administered to produce levels of between 40 ng VIIa/ml and 700 ng FVIIa/ml of plasma.  The effective dosages of both tTF and VIIa/factor VII  activator are significantly and surprisingly less than the administration of either alone to stop bleeding. Examples demonstrate safety and efficacy in normal and hemophilic dogs.
