Abstract: ABSTRACT          A   fuel   injection   control   system   utilizes   a microprocessor  to calculate  and generate  one  or more  logic control   signals   that   determine   the   duration   of   the energization time of intermittently energized electromagnetic fuel  injectors. The microprocessor  has a number of  inputs which  are  indicative  of  engine operation,  such  as  intake manifold vacuum, engine crankshaft position and speed, engine operating temperature, and perhaps less important parameters. During  engine  cranking  most  of  these  parameters  are  not available.  The invention overcomes this problem with the use of  an  analog  computer  that  shares  circuitry  used  by  the microprocessor when the microprocessor is either in a default mode of operation or when the engine is being cranked.

Abstract: APPLICATION NO.  :  366,681 APPLICANT        : Johann D. Rittberg 13975 - 94 (A) Ave., Surrey, B. C., Canada, V3V 1N3.          TITLE            : ROTARY ENGINE OR PUMP                            ABSTRACT      The invention is concerned with an internal combustion engine.  The combustion of fuel happens without interruption and is similar to a turbine engine.  The engine comprises of motor, compressor and pumps for fuel and oil.  The rotors - which do not actually "rotate" but slide in a circular motion within the constraints of two guideshafts - in the motor, compressor and pumps are always of the same structure.          This is the basis of the invention.  The structure consists of a smaller inner arc structure and a larger outer arc structure.  Each arc structure is com-posed of two or more different sized arcs.  The two ends of the arc structure do not meet, but the sum of the angles of all the arcs making up the structure equals 360°.  The inner and outer arc structures are joined at the ends and form, with the space between them, an independant rotor.    Within the rotor and between the two arc structures, the driveshaft is aligned triangularly to the two guideshafts.          All three shafts have cams of identical eccentric radii.  The interior of the housing has the same form as the rotor but is larger by the eccentric radius of the cams.  The rotor is totally independant of any moving guidewalls or drive gears, Because of the arc structure, the movement of the rotor and the flow of gases or fluids is: enclosed, unlike a turbine; uninterrupted, unlike a piston engine; and free of inter-ferences and heavy guidewalls, unlike some previous inventions.

Abstract: METHOD FOR ACHIEVING IDEAL IMPURITY     BASE PROFILE IN A TRANSISTOR                      ABSTRACT            A method for making a transistor having base, collector, and emitter regions, where the impurity doping profile of the intrinsic and extrinsic base regions can closely approximate that which is ideal for the transistor.  The extrinsic and intrinsic base regions are formed in separate steps, where the extrinsic base region is formed first, followed by formation of the intrinsic base region.  The portion of the extrinsic base region located over the area where the intrinsic base region is to be formed is removed, leaving an opening through which both the emitter and the intrinsic base regions are formed.  Thus, the effect of the step in which the extrinsic base region is formed is removed prior to formation of the intrinsic base region.  Further-more the extrinsic base region is protected during formation of the intrinsic base region.  This technique can be applied to processes using either ion implantation or diffusion to form the emitter and base regions of the transistor.

Abstract: ABRASIVE BRUSHES AND METHODS OF MAKING SAME               Abstract Of The Disclosure An elongate, abrasive strip element is produced by winding an abrasive monofilament, or bundles thereof, back and forth in a zigzag pattern from side to side of the strip, and chain stitching together adjacent transverse sections of the  mono-filament, or bundles therof.  The resultant strip is easily rolled or coiled about a transverse axis, but resists bending about a longitudinal axis, whereby it can be manipulated readily to form brush faces of various configurations.  The warp yarns which are used to produce the chain stitches may be produced on a knitting machine which can be cammed to vary the number of stitches between adjacent-transverse strands of the monofilament wefts, thereby selectively to vary the density of the brush faces produced from the strips, and also to vary the configuration of the abrasive strip itself (i.e to produce it in linear form, circular, truncated-conical, etc.).  The linear form of the strip may be severed medially of its edges to form two, identical bristle strips, each of which may be wound in convolute form, for example, and may be embedded at one side (e.g. by molding) in an elastomeric base to form a disc type brush.  Other brush con-configurations are also disclosed.

Abstract: CLOSED PRESSURE ACTUATED SYSTEM       FOR PLACEMENT BUCK                   ABSTRACT A placement bucket for placing material such as concrete in forms by manipulation of clam shell gates in response to action of a power cylinder makes use of a hydraulic fluid system which prevents opening the gates of a full or partially full bucket of material unless there is a sufficient reserve of pressure and fluid volume to make certain of closing the gates at any time. The system is provided with a precharged fluid supply under pressure into which additional fluid is diverted when generated in a master cylinder by lifting a piston against the weight of the bucket and its contents. A sequence valve prevents flow of fluid to the power cylinder until an optimum amount of fluid pressure and volume is reached.   An auxiliary direction valve in a fluid return line can be manipulated to temporarily block return flow of fluid from the exhaust side of the power cylinder to a reservoir, in that way to temporarily fix the partially of full open position of the gates.

Abstract: ABSTRACT          A method of pulsed direct current (DC) arc welding is disclosed wherein special pulses of positive direct current are used to weld together work pieces.  The special pulses increase the magnitude of the current flowing across the arc gap to a peak value which can provide sufficient power to melt the work pieces and which is of sufficient magnitude that a power flow is pro-vided which is capable of dissipating oxides on the surfaces of the work pieces during the time interval in which the increase in current flow occurs.  Thus, the special DC pulses are capable of dissipating difficult to reduce oxides which may be present on the surfaces of the work pieces without using a flux as required in certain prior arc welding processes.  Also, the method ac-cording to the present invention is especially useful for flux-less arc welding of aluminum, particularly thin wall aluminum tubing used in making heat exchangers for air conditioning systems, for which conventional alternating current (AC) and DC arc welding techniques are not particularly suitable.  Further, the method according to the present invention has the advantage of precise power control to work pieces, a feature not easily or readily attained by many conventional arc welding techniques.

Abstract: MONITORABLE BONE GROWTH STIMULATOR              Abstract of the Disclosure There is disclosed an implantable bone growth stimulator whose direct-current output can be monitored.          Rather than to interrogate the device, e.g., by using a control magnet as in the heart pacer art, the device continuously transmits pulses of electromagnetic energy at a rate proportional to the current being delivered.          The continuous transmission expends no more than about five percent of the total power.  Instead of using an electrode lead as an antenna for radiating the pulses, a separate coil inside the device is utilized so that the therapeutic current itself is in no way affected by the pulse transmission.  Effective transmission is achieved despite the fact that the device is hermetically sealed in a titanium case.  Also included is an electronic switch for drastically limiting power drawn from the battery until implantation takes place, in order to provide an extended shelf life.
