Abstract: FUEL INJECTOR              ABSTRACT OF THE DISCLOSURE    This disclosure relates to a unit-type fuel injector for an internal combustion engine such as a reciprocating piston internal combustion engine.  The injector includes an injector body forming a plunger bore, and a plunger that reciprocates in the bore.  A fuel supply passage and a drain passage are formed in the body, and a fuel injection chamber is formed at the lower end of the plunger bore.  A feed hole connects the chamber with the supply passage, and a scavange passage connects the supply and drain passages.  During a retracted plunger, or fuel metering, portion of the injector cycle, the plunger opens the feed hole and closes the scavange passage, and during a down plunger, or scavenging, portion of the injector cycle, the plunger closes the feed hole and opens the scavange passage.  An annular groove is formed between injector parts and surrounds the chamber, and the groove collects leakage.  A restricted bleed hole connects the groove with the low pressure drain and removes the leakage.  The feed hole is at an end of the supply passage, and the incoming fuel flows in a direct path through the supply passage and feed hole to the injection chamber.

Abstract: Title Method and System for Reproducing Identification Characters Abstract of the Disclosure A method and system are described for producing identification characters that are both man and machine readable.  The identification characters, such as those on a patient's I.D. bracelet or an inventory control tag, are scanned with an optical character reader.  The character information obtained from the reader, or other input source, is processed and used to control the reproduction of the identification characters using a dot matrix printer.  The readability of the characters is enhanced by using thermal paper and increasing the heat applied by the dot matrix printer to (1) enlarge the area of the dots and (2) increase their optical absorbance.  The increased area and absorbance produces an apparent solid line character which is more easily readable by an optical character reader.

Abstract: A B S T R A C T            A method for recovering high-grade, preferably sulphur-free fuel from bituminous or pyrobituminous mineral-fuel materials, such as coal, oil shale and alum shale, said method comprising finely-dividing the raw material and dividing said material into at least one fuel concentrate and a residual product which is bound to a durable agglomerate form by means of a binder. The method is charac-terized in that the raw material, subsequent to finely-dividing the same to a sufficient particle size physically, is divided into a high-grade, preferably sulphur-free mineral fuel concentrate containing a given quantity of ash-forming minerals adjusted relative to the con-tent of ash-forming minerals of the raw material, and into a residual product comprising substantial ash-forming minerals. A binder for hydraulically binding the residual product to a durable agglomerate is produced from the fuel concentrate by combusting the same while using the fuel content of said concentrate.

Abstract: ABSTRACT OF THE DISCLOSURE      A method of controlling strip temperatures of two joined metal strips of dissimilar gauges but requiring essentially the same heat treatment temperatures, is described.  The normal processing temperature is higher than the temperature to which it is desired to heat the webs.  The higher processlng tempera-ture is reduced to a lower temperature in response to a change in the gauge of the webs passing through the chamber in which the webs are heat treated.  This lower temperature is such that the heavier gauge web will not be underheated and the lighter gauge web will not be overheated.  The line speed at which the juncture of the webs passes through the chamber will simultaneously be lowered in correlated relation to the reduc-tion of the temperature within the heat treatment chamber unitl such time as the juncture passes from the chamber so that the processing conditions of time and temperature can be readjusted to accommodate heat treatment of the new web.

The p-n junctions comprise a plurality of separate regions which extend a distance into a semiconductor body from a surface thereof and have a conductivity type opposed to that of the body.  A region of the same conductivity type as that of the body extends a further distance into the body and is composed of sub-regions which overlap one another in the direction parallel to the surface of the body.  The elements so formed have a more uniform avalanche gain and, because of the overlap of the sub-regions of first conductivity type, the likelihood of electric breakdown at the surface is reduced and the electrical isolation between the elements is increased.  Moreover, because of the proximity of the adjacent elements the likelihood of breakdown at the junction edges is reduced.
