Patent EP-0209261-A2 (EP)
Inventor: NAJJAR MITRI SALIM
IPC: C01B3/38
Filed: 1986-06-19
Abstract: Synthesis gas is produced by the partial oxidation of a feedstock comprising petroleum coke and/or heavy liquid hydrocarbonaceous fuel containing sulfur and having an ash that contains nickel, vanadium and silicon. An iron-containing additive is introduced into the reaction zone along with the feed. In low silicon feedstocks, the additive combines with at least a portion of the nickel constituents and sulfur found in the feedstock to produce a liquid phase washing agent that collects and transports at least a portion of the vanadium-containing oxide laths and spinels and other ash components out of the reaction zone. A minor amount of an additional material selected from the group of elements consisting of magnesium, chromium and mixtures thereof is optionally included in the iron-containing additive. The iron-containing additive may be uniformly dispersed in petroleum coke having a nickel and vanadium-containing ash. By this method, molten slag having a reduced viscosity and containing the nickel-­and vanadium-containing impurities from the feedstock are readily removed from the gas generator at a lower tempera­ture. Further, the life of the refractory lining is extended. With higher silicon feedstocks, an iron and calcium-containing additive is used. Separate portions of the additive (i) generate the liquid phase washing agent and (ii) combine with a portion of the nickel, calcium and silicon to generate a liquid oxide-silicate phase that fluxes e.g. dissolves substantially all of the remaining portion of said vanadium-containing oxide laths and spinels and other ash components.

Abstract: Disclosed is a Complementary Cascoded Logic (C²L) Circuit which performs the AND-INVERT (AI) (or NAND) function. The AND function is implemented with input PNP transistors (T1, T2, T3) and the invert function is implemented with a first NPN transistor (T4). An inverted NPN transistor (T5) serves as a current source for the first NPN. A first low voltage Schottky diode (D3) is serially connected between the emitter of the first NPN transistor (T4) and the emitter of the inverted NPN current source transistor (T5). The first Schottky diode (D3) precludes, under certain conditions, simultaneous conduction of the first NPN transistor (T4) and the inverted transistor (T5). Oppositely poled second and third low voltage Schottky diodes (D1, D2) are utilized via an emitter follower output (T6) to provide an output voltage swing of V R  ± V F , where V R  is a reference voltage and V F  is the potential drop across a Schottky diode. The low power high speed logic circuit (C²L) has particular utility in redundant circuit applications.

Abstract: The present specification discloses a disc brake (1) for use on a commercial vehicle. Traditionally drum brakes have been used on the light to medium weight range of commercial vehicles, one disadvantage of conventional hydraulically actuated disc brakes (1) lying in their unsuitability for the provision for a parking/emergency brake, primarily due to the bulk of such extraneous items. 
     The present invention provides a disc brake (1) having a brake actuation mechanism (7) which is movable axially by brake applying means (3) mounted in a part of the disc brake (1). The brake applying means (3) has an axis of actuation (Y) which extends in the same general direction as the axis (Y) along which the brake actuator (7) moves to apply the brake (1). This construction leads to a compact overall design wherein the brake applying means (3) is part of the brake (1) itself.

Abstract: A device for determining the depth of anaesthesia of a patient, includes means (1) for measuring on a body part (2) an optical parameter, such as transmission or reflection, which is influcenced by the circulation of the blood through this part of the patient's body, and to produce an electric signal which varies in accordance therewith. This signal is related to the heart frequency of the patient and shows a maximum amplitudes and minimum amplitudes which are related respectively to the systolic and diastolic blood-­pressure of the patient. The signal is applied to signal processing circuits (3) which determine the variation of the period of the signal (Δ (R-R)) and the variation of the pressure values, e.g. maximum amplitude (Δ P<sub>max</sub>) or minimum amplitude (Δ P<sub>min</sub>) or the difference between its maximum and minimum amplitudes (Δ (P<sub>max</sub>-P<sub>min</sub>)).A magnitude (K) which is proportional to the variation of the period of the signal or is preferably proportional to the ratio between the variation of the period of the signal and the variation of the pressure values is presented as a measurement of the depth to which the patient has been anaesthetized.

Abstract: In accordance with an embodiment of the present invention, a substantially rigid, multi-well, self-pipetting device for use in chemical, immunochemical and microorganism analysis is provided. The device includes a substantially rigid, substantially planar frame having, in operational orientation, a front face, a back face, a top edge and a bottom edge. A plurality of test wells are disposed within the device between the front face and the back face, usually in a linear array. A filling manifold is located within the device. The filling manifold is in fluid communication with each of the test wells through a filling passageway. A docking port is provided in the device which is adapted for receiving a reservoir holding a fluid specimen. The docking port is disposed on a peripheral surface of the device. The docking port is in fluid communication with the filling manifold through a filling port and a filling channel disposed within the device. With the device in its operational orientation, the test wells, filling channel, filling manifold and filling port are located at a level lower than the surface of the fluid in the reservoir. 
     The device has a vent control system, also in fluid communication with the test wells, which is comprised of one or more vent manifolds, and/or valves to a vent manifold, and/or one or more vent holes or other passages to the ambient atmosphere. These vent holes, if present, are temporarily closed by a film or other means. With the device in its operational position, the vent manifold and/or vent holes of the   vent control system are positioned higher than the surface of the fluid in the reservoir. The test wells are connected to the filling manifold and the vent control system according to the filling sequence. The reservoir is also connected to the vent control system through a vent port and a vent channel. The fluid specimen in the reservoir therefore flows down to the filling manifold by gravity and fills the test wells vented to the reservoir or to the ambient atmosphere.

Abstract: A centrifugal compressor (11) has a diffuser (28) with fixed vane geometry which provides a significantly increased operating range, as compared to conventional fixed geometry diffusers, by developing what appear to be flow-accelerating stall bubbles (46) in a throat of the diffuser (28) that forestall the onset of surge in the portion of the operating range near and approaching the surge point. The stall bubbles (46) are created by fixing the suction sides (40) of the vanes (31), relative to the flow impinging upon their leading edges, at angles slightly more radially inclined than is conventional, thereby creating higher than normal angles of incidence with the flow delivered by the impeller (18) of the compressor (11).

Abstract: Low loss semiconductor waveguides for supporting propagation of optical signals over a wide range of wavelengths are achieved by growing at least two epitaxial layers (12,13) of dopant material contiguous along a major surface of each layer to form a heterointerface  (14) therebetween. At least one (12) of the epitaxial layers (12,13) includes a sufficient concentration of semiconductor material to cause strain via lattice mismatch substantially at and near the heterointerface (14). The strain induces a change in refractive index such that the heterointerface (14) exhibits a substantially higher refractive index than a portion of each epitaxial layer (12,13) proximate to the heterointerface. The resulting waveguide is capable of supporting propagation of optical signals substantially along the heterointerface (14). 
     In one example, contiguous epitaxial layers of InP (13) and InGaP (12) form a waveguide for optical signals at wavelengths greater than 0.93 µ m . The concentration of Ga in the InGaP epitaxial layer (12) is varied from 10¹⁸ to 10²⁰ cm ⁻³ to increase the refractive index difference between the heterointerface (14) and the immediate surrounding layers (12,13).

Abstract: A latch assembly having a latch body (12) adapted to be coupled to a generally fixed support, such as a chassis unit, wall or post. The latch body (12) has a groove (44) for removably receiving a retained pin (14) which is adapted to be mounted on a movable structural member to be latched, such as a door, support arm, gate or the like. The latch body (12) further includes a latch pin (16) which is spring biased into engagement with the retained pin (14) when the retained pin is received in the groove (44) of the latch body. The inter-engagement of the retained pin (14) and latch pin (16) is such that the retained pin is restricted against movement in three mutually perpendicular directions, namely the x, y and z directions. The retained pin (14) has a pair of spaced, cylindrical parts (48) on opposite sides of a pair of bevelled parts (49,50) which converge toward each other to an annular junction (51) therebetween. The latch pin has a conical end portion (39) for engaging the bevelled parts (49,50) of the retained pin to resist axial movement of the retained pin in the z direction. The engagement of the cylindrical parts (48) of the retained pin (14) with the surfaces of the latch body (12) defining the groove (44) resists movement of the retained pin in a pair of mutually perpendicular directions, namely the x and y directions.

Abstract: An active paper drop mechanism (20) for ink-jet printers is provided. The mechanism comprises a pair of opposed, movable rail members (22) associated with opposed walls (14) of a horizontally-disposed output collection tray (12) for receiving sheets (10) of printed media. 
     In particular, each rail member is provided with return spring (26) that act to maintain the rails in a closed position. In that position, the rails support a sheet of the print medium during the printing opera­tion, thus giving the ink on the previously printed-on sheet (10′) time to dry. 
     The rails are provided with a wing member (32) and are pivotally secured (38) in the floor of the output tray, with the pivot point spaced inwardly from the wing member. Downward pressure against the wing member thus causes the rail to rotate outward from its closed position, into a recess (24) provided in the side of the output tray. This provides sufficient clearance for the sheet to drop into the output stack. Upon release of the downward pressure, the spring causes the rail member to return to its original closed position.

Abstract: In a method for plating one side of a woven fabric sheet, a backing layer is applied to one side of the sheet. The sheet and backing layer are wetted in an electrolytic solution containing metallic ions to be deposited on one side of the fabric sheet only. Air bubbles trapped in interstices of the fabric weave and beneath the backing sheet prevent the electrolytic solution from soaking through the fabric sheet. Electrodes bond the metal ions on the wetted fabric thereto. The backing sheet is then removed. The resulting fabric is coated only on one side and the interstices are not filled in by plating material. The fabric is useful as the outermost layer in a composite laminate for an aircraft skin.
