Abstract: A PLANAR NARROW-STRIPE LASER WITH IMPROVED CHARGE CARRIER CONFINEMENT            Abstract of the Disclosure Double heterostructure lasers which use a narrow stripe contact exhibit linear characteristics with a low lasing threshold current making them very suitable for fiber optic communication systems. Linearity and low threshold currents are achieved if the carrier current injected into the device is confined to a narrow region of the active layer.  To further confine the current a p-type diffusion is performed to produce a relatively low conductivity path between the contact stripe and the lasing region of the active layer.  Ideally the diffusion front extends to within 0.5 microns of the active layer.  In order to achieve this, a p-type double heterostructure second confining layer of 0.5 microns or less is grown immediately adjacent to the active layer and an n-type blocking layer is grown on the second confining layer. By diffusing the p-type dopant through the n-type blocking layer the diffusion front can be accurately monitored using a scanning electron microscope.  As soon as the diffusion front merges with the p-type second confining layer then it can be concluded that it is within 0.5 microns of the active layer.          Moreover the pn junction between the second confining layer and the blocking layer is reverse biased in use and so provides further charge carrier confinement in comparison with the conventional wholly p-type second confining layer which is usually of the order of 1.5 µm thick.                            -i-

Abstract: Dynamic Low Tire Detection System Abstract A dynamic low tire pressure detection system for detecting the presence of a low tire mounted on a structural member of an aircraft, such as a bogie beam or nose axle, includes a pair of inclinometers mounted on the  structural  member  and  adapted  to  sense  the  bend therein.  The signals from the inclinometers are combined to generate signals representing the weight carried by the structural member.  When the aircraft is moving, the weight signal is analyzed to determine whether particular frequency components are present therein.  The amplitude of these frequency components are modified by a gain fac-tor dependent upon a reference amplitude and are added to develop a tire  pressure signal.  The tire pressure sig-nal  is  compared  against  a  trip  setting  to  determine whether the tire pressure is within acceptable limits. If the tire pressure is outside of the range of accept-able tire pressures, a signal is generated to warn of a potentially dangerous condition to the aircraft operating personnel.

Abstract: ABSTRACT OF THE DISCLOSURE           A microcomputer is used in the invention for the control of the ignition function of an ignition system of an i.c. engine.  The limitation of r.p.m. of the engine at high r.p.m. is brought about by an acurately developed procedure of delayed ignition in two steps.  The control of ignition timing is carried out by means of timer pulses between reference points, whereby the number of pulses between such points constitutes an address of a position in the ROM of the computer, where a reference number of the ignition time is stored.  A delayed ignition can be programmed in the memory so that the ignition characteristic gets the shape shown in the Figure.  In manufacturing of a great assortment of engines several demands for limitation of maximum r.p.m. can be fulfilled in that the microcomputer has a spacing for storing several characteristics.  The selection of a particular characteristic for a sort of engine is made by establishing permanent connections (or disconnections) in separate inputs of the computer which reads the combination and choses the corresponding characteristic.

Abstract: The fuel system of a diesel powered vehicle is kept free of wax blockages during cold weather by a mixing unit which is submerged in the fuel tank and furnishes to the fuel pump a waxing resistant supply stream comprising a warm fraction derived from the excess fuel by-passed by the engine injectors and a cold fraction derived from the stored fuel in the tank. The unit delivers to the pump a controlled portion of the excess fuel whose size depends upon the rate of flow, so that the supply stream contains substantially all of the excess fuel when the engine is operating at full throttle, but contains only a selected fraction of the excess fuel when the engine is idling. The balance of the excess fuel available at idle is discharged into the tank. The mixer requires no thermostatic element or other moving parts, can be installed without structural modification of the tank, and keeps the system free of wax blockages without overheating the fuel oil. An improved fuel system incorporating the mixer embodies a heat exchanger for the excess fuel returned to the mixer, and a selector valve which is used to terminate the heat exchanging and mixing functions in the warmer seasons of the year. BACKGROUND OF THE INVENTION Diesel power plants for locomotives and trucks include a fuel system which supplies the engine injectors with fuel at

Abstract: CUTTER CONFIGURATION FOR A GAGE-TO-SHOULDER   TRANSITION AND FACE PATTERN            Abstract of the Disclosure Shortening of the bit life  and  premature  failure of cutting elements on a rotating bit near or at the gage of the bit can be avoided by disposition of the cutting elements at or below a key level on the shoulder-to-gage transition.  A first tooth is placed on the shoulder of a rotating bit at the key level.  The key level  is defined  as  that  point  on  the  shoulder  of  the rotating bit at which a tooth extends radially from the axis of the  rotating  bit  by  a  distance  substantially  equal  to  the diameter of the bore drilled by the rotating bit as also defined by the gage diameter of the rotating bit.   Below the key level the teeth are set on the pads in a staggered pattern that serve to  increase effective cutting  element concentration.

Abstract: Abstract of the Disclosure:  A mixture which is azeo-tropic or which behaves almost azeotropically and is difficult to separate by distillation, is separated into two pure or substantially pure fractions by distillation, by adding a further component, using a procedure which is similar to extractive distillation and is carried out in a distillation column, a section of which is divided into a feed part and a take off part by means of a separating unit which is effective in the longitudinal direction and completely or partially prevents cross-mixing of liquid streams and/or vapor streams.  In this process, the azeo-tropic mixture is fed as bleed streams to the feed part and to the take off part, in each case at or near the top, and one of the two pure or substantially pure fractions is removed as a top product from the distillation column while the other is removed as a side product from the take off part.
