Granted: 1991-04-16
Abstract: WIND-RESISTANT OUTDOOR HEATING APPLIANCE                 A B S T R A C T     An outdoor heating appliance includes a top struc-ture having a top surface, a stationary airfoil, and exhaust openings for flue products.  The operation of the heating appliance is rendered wind resistant by generating with the stationary airfoil, in a region above the top surface and in response to wind, an air pressure lower than an air pressure of that wind, and by locating the exhaust openings in that region, whereby the flue products axe exhausted from the outdoor heating appliance by the wind.  An inlet opening may be provided below the top surface at the airfoil for receiving part of the wind, in order to sustain combustion and generate inside the heating appliance positive pressure toward the exhaust openings by guiding air from the received part of the wind through a channel to a burner in the heating appliance.

Granted: 1992-01-14
Abstract: "PROCESS FOR PURIFICATION OF A GAS STREAM BY A NITROGEN SCRUBBING" In a process proposed for purification of a gas stream at elevated pressure by nitrogen scrubbing, the gas stream to be purified and the nitrogen scrubbing stream are initially cooled to low temperatures. The gas stream is then scrubbed with liquid nitrogen and the purified gas stream is mixed with cooled, high-pressure nitrogen to form a mixture in which nitrogen accumulates partly as a liquid phase. The mixture thus formed is then heated and the liquid nitrogen contained therein is evaporated. Prior to scrubbing, either the nitrogen scrubbing stream itself or a partial stream of the nitrogen scrubbing stream or another process stream under a pressure lower than the working pressure of the nitrogen scrubbing step is at least partly condensed and then pumped to a higher pressure. The condensation of this low-pressure stream provides a reduction in the temperature difference at the cold end of the heat exchangers upstream of the scrubbing step resulting in the reduction of the energy requirements of the process.

Title: Drag reducing device for multi-truck shipment when mounted
Inventor: WILEY NATHANIEL C JR
IPC: B62D35/00
Filed: 1987-10-29
Granted: 1992-05-26
Abstract: ABSTRACT      The rooftop drag reducing device comprises a top and a bottom and may be mounted to the cab of trucks for semi-trailers at the factory.  The device may then be conveniently collapsed with the top fitting inside the bottom when multiple trucks are shipped with the second and third truck, for example, having their front wheels mounted to the fifth wheel of the truck in front of them.  Since the drag reducing device has had its height reduced it will pass under low bridges.  The device is initially integrally molded in one piece and cut into the top and bottom portions along a oblique cut line step.  The top may be left connected to the bottom at the front to form a living hinge.  Alternatively, a piano hinge may be used to connect the top and bottom portions at the front thereof.  Bolts along the sides are used to hold the top in its upright position.  These bolts pass through stepped side flanges which strengthen the device.  The rear of the top is closed to form a rigid box-like structure to resist sway.  Trim tabs may be integrally molded into the top at its rear.  Each trim tab is preferably only cut out three quarters around its perimeter so that it remains mounted at the front thereof to the top by a living hinge of molded material.  The device may be mounted to the roofs of truck cabs by conventional brackets or by means of bolts through an integral horizontally disposed flange around its lower periphery.

Abstract: Abstract of the Disclosure An apparatus  for metering,  measuring,  or dosing flowing media.   A distribution slide valve is disposed in a housing between an inlet and an outlet.  A metering piston is disposed in a chamber of the housing and divides the chamber into a first and  a second metering chamber.   The two end positions of the slide valve alternately connect the metering chambers to the inlet or outlet.          Transfer passages are disposed on the periphery of the  slide valve  for  selective  connection of connecting passages to the inlet, the outlet, and the metering chambers.  A transverse connection of the slide valve connects a central control channel thereof to the  inlet via a  first one of the transfer passages in either of the end positions of the  slide valve.   Each end of the  latter is associated with a hydraulic control chamber into which the control channel opens.   Relief passages connect the control chambers to the outlet.   A piston rod connected to the metering piston extends axially displaceably through the larger diameter control channel, with the slide valve being axially movable relative to the piston rod.   Sealing elements are disposed on the piston rod, with the control channel being adapted to be alternately sealed off relative to one or the other of the control chambers via these sealing elements.

Title: Hidden line removal method with modified depth buffer
Inventor: GONZALEZ-LOPEZ JORGE
IPC: G06T15/40
Filed: 1988-08-04
Granted: 1992-10-20
Abstract: HIDDEN LINE REMOVAL METHOD WITH MODIFIED DEPTH BUFFER Abstract of the Disclosure Polygon vertex data is processed in three steps to create a graphics display without hidden lines and without gaps in the displayed lines. The technique permits the processing of triangles rather than polygons having four or more sides. In the first step, the Z values for the display points for the visible edges of the polygons are identified and assigned a reserved value ZCLOSE in a frame buffer. In the second step, the polygons are tessellated into triangles and the Z values for the display points on the triangles are computed and each depth buffer storage location is updated so as to contain the value of points closest to the viewpoint while the frame buffer is written with a background color. In the final step, the Z values for the display points of the polygon edges are again computed and compared-with the corresponding Z values in the depth buffer. The depth buffer is updated with the computed values if the stored value is equal to ZCLOSE or if the computed value represents a position closer to the viewpoint than the stored value and the frame buffer is then written with a foreground color for the display point in question.

Abstract: ABSTRACT OF THE DISCLOSURE:     The invention concerns a process and an equipment for pretreatment of cellulosic chip-formed raw-material by impregnation.  In the process,  first a vacuum treatment is carried out withou preceeding moistening treatment,  and as soon as possible after the vacuum treatment penetration, is carried out with a solution of chemicals or with water at the atmospheric or a higher solution pressure.  In this way the fiber cavities can be filled optimally, which promotes a uniform and adequate diffusion of the solution into the fiber walls significantly.  The process can be carried out, e.g.,  in a device which comprises a tank for the treatment of the raw-material and therein a feed opening for the solution as well as an opening for removal of the raw-material,  which opening communicates preferably with a reception tank,  where the atmospheric or a higher pressure prevails.
