Patent EP-0127077-A2 (EP)
Title: A rotatable drill bit
Inventor: GRAPPENDORF RICHARD H
IPC: E21B10/26
Filed: 1984-05-17
Abstract: Shortening of the bit life and premature failure of cutting elements (88,70) on a rotating bit (32) near or at the gage (64) of the bit (32) can be avoided by disposition of the cutting elements (88) at or below a key level (72) on the shoulder-to-gage transition. A first tooth is placed on the shoulder of a rotating bit at the key level (72). The key level (72) is defined as that point on the shoulder (62) of the rotating bit (32) at which a tooth (74) extends radially from the axis (54) of the rotating bit (32) by a distance substantially equal to the diameter of the bore drilled by the rotating bit (32) as also defined by the gage (64) diameter of the rotating bit (32). Below the key level (72) the teeth (74) are set on the pads in a staggered pattern that serve to increase effective cutting element concentration. The staggered pattern is repeated within a pad and between pads in selected areas. Distinguishable cutting elements are alternated within the pattern.

Abstract: A process is disclosed for recovering fats and oils from oil fruits and oil seeds, wherein the oil fruits and oil seeds are cleaned, immediately thereafter pressed cold in a screw press without prior mechanical conditioning, and then extracted. In this process, the extraction is effected immediately after pressing by treating the oil fruits and oil seeds with countercurrently flowing carbon dioxide, ethane, ethene and/or propane at a temperature of from 40 DEG  to 110 DEG  C. and at a pressure of from 250 to 750 bar, for a time period of from 0.5 to 2.5 hours, with the solvent ratio lying between 5 and 30 kg solvent per 1 kg pressed cake. The separation of the extracted fats and oils from the separated solvent phase is effected by pressure reduction and/or temperature change. The invention also includes an apparatus for implementing the process.

Abstract: A new reactor for the production of carbon black, a new method for the production of carbon black, and a new carbon black are disclosed. The carbon blacks are characterized by a surface area preferably in the range of 70 to 150 m 2 jg and "G" values of either less than 1.20 or greater than 1.85, corresponding to very narrow or very broad aggregate size distributions, respectively. The reactor is preferably for axial flow of combustion gases and is characterized by serial arrangement of a cylindrical combustion zone, a frustoconical converging zone, a throat, an abrupt diverging zone and a cylindrical pyrolysis zone. In certain apsects of the invention, the combustion gases are formed by combusting low BTU fuel and forcing these gases through the throat at a velocity approaching Mach 1. In one method of carbon black production, the feedstock is introduced into the converging zone. In another method, it is introduced as a spray. In other methods, the feedstock is introduced with upstream or downstream velocity components.

Abstract: O A sheet carrying an image stored therein is scanned by a light beam emitted by a light source. Light which is obtained by the scanning of the sheet and which carries the image is detected by use of a photomultiplier. When the level of output current of the photomultiplier becomes higher than a predetermined standard level, the intensity of the light beam is decreased so that the level of the output current of the photomultiplier does not exceed the predetermined standard level, thereby preventing the photomultiplier from being broken by light of high intensity.

Abstract: A device for delivering flavor utilizing a flavor carrier in powdered form. A preferred embodiment of the system may resemble a conventional cigarette, and includes an overwrap defining a path of airflow through the device, a chamber containing particulate matter, and a means for entraining the particulate matter in the airflow. The overwrap may be a tube, resembling a conventional cigarette in appearance, feel, and draft. A means for entraining the particulate matter may be an intake flow limiter having a passage therein which causes a thin stream of high-velocity air to impinge upon the particulate matter, entraining it in the airflow. Alternately, the entraining means may be a series of baffles or similar components which produce a turbulent airflow, thus entraining the particulate matter. Output means are also provided for eliminating stoppages and for delivering the airflow, with particulate matter entrained therein, to the user.

Abstract: An endoscope sheath having a flexible tube surrounding the elongated core of an endoscope. The flexible tube has a transparent window near its distal end positioned in front of the viewing window of the endoscope. Channels for taking biopsies, injecting air or injecting water to wash the window of the sheath may extend along the endoscope, either inside or outside the sheath. Where the channels are positioned inside the sheath, they may be inserted in a longitudinal groove formed in the endoscope core. The protective sheath may be used with either end-viewing endoscopes or side-viewing endoscopes. In the latter case, the channel for taking biopsies extends through an elongated elastomeric membrance so that a catheter through the biopsy channel may be moved longitudinally by manipulation of an elevator. The protective sheath may be installed by rolling the elastomeric tube into an annular configuration and then unrolling the tube over the core of the endoscope. Alternatively, the tube may be inflated in its unrolled configuration to expand the tube and allow it to be easily slipped onto the endoscope core. A variety of specialized endoscopes may be created by using protective sheaths having a variety of special purpose medical instruments mounted at the end of a biopsy channel and operated through the channel.

Abstract: A phthalic anhydride product having a particle configuration made up of a mixture of spheroids, needle-like crystals, and amorphous particles is produced by feeding molten phthalic anhydride at a temperature between 131° and 155° into a spray nozzle in a closed cycle congealing chamber. The molten phthalic anhydride is discharged from the spray nozzle into a co-current or counter-current flow of inert gas at a temperature between -10° and 70°C, in order to congeal the product, which is then removed and transferred to a hopper or other storage means. For nozzle orifices having a diameter from 1 to 4 mm, discharge pressures of between 10 and 300 pounds per square inch are employed. in an especially preferred embodiment, the needle-like crystalline configurations are disjoined from the spheroids, thereby increasing the bulk density of the product, which in all embodiments exhibits the combination of superior flowability and more rapid dissolution, when compared with prior art products.

Abstract: An addition correction term (lat) is added to a feedback control term (Ifb) when an internal combustion engine is idling, a control valve (30) is under feedback control, and an automatic transmission is in drive range (D range).The addition correction term (lat) is calculated by multiplying a predetermined constant value (lato) by at least one of the correction coefficients which are decided based on RPM and temperature of the engine and vehicle speed. A learnt value (Pbref) is calculated based on an intake manifold (33) pressure when an internal combustion engine is in idling condition, the control valve (30) is under feedback control, and an automatic transmission is in disengagement condition, for example, neutral range (N range). When the automatic transmission is turned into D range, an existing manifold pressure is detected and the addition correction term (lat) is calculated based on an difference between the learnt value and the detected manifold pressure.
