Title: Fuel injection nozzle
Inventor: AVDENKO ANATOL
IPC: F02M51/02
Filed: 1990-05-09
Abstract: FUEL INJECTION NOZZLE            Abstract of the disclosure A fuel injection nozzle has a tubular body adapted to receive fuel, a tubular seat member mounted to the body, the seat member having an opening for discharging fuel and a valve seat surrounding the opening, a poppet valve member engageable with the valve seat to interrupt fuel flow through the opening, and an extension spring anchored to the body and to the valve member and biasing the valve member to engage the valve seat.  The extension spring is a helically coiled spring with each coil lying close to the adjacent coils and with the coils at one end overlying an end of the body to anchor the spring to the body and to cause fuel flowing through the nozzle to pass between the coils of the spring; the spring thereby acts as a filter for fuel to be discharged by the nozzle.  The seat member is axially movable relative to the body to adjust the length of the spring and thus the bias on the valve member whereby the desired valve-opening pressure differential may be established.  The body is adapted to receive fuel through a restriction member that limits fuel flow through the opening.  The valve member has a shank with a valve element at one end and a head at the other end, the shank being formed as a pin and the valve element as a ball that is welded to the pin. The coils at the other end of the spring surround the head to anchor the spring to the valve member.  The body is adapted to receive fuel through a plastic fuel line having one end secured about the body and having an integral flange ultra-sonically formed on the other end to facilitate assembly to a source of fuel.  The nozzle is received in a mounting bushing that has a central bore with an annular groove receiving and retaining a locating flange on the nozzle, and that has a plurality of peripheral beads adapted to sealingly secure said nozzle in an engine.

Abstract: ABSTRACT OF THE DISCLOSURE      A method for adjusting a spinning piezoelectric beam of a dual-axis angular rate sensor, in which the spinning piezoelectric beam is excited in a direction at right angles to the lengthwise direction of two piezoelectric sensors and to a rotary shaft; detected voltages of the two piezoelectric sensors are measured by a signal measuring circuit; a bending portion of at least one of the two piezoelectric sensors is ground so that the levels of the two measured signals and the difference therebetween become small; the spinning piezoelectric beam is excited again in the lengthwise direction of the piezoelectric sensors at right angles to the rotary shaft; detected voltages of the two piezoelectric sensors are measured by the signal measuring circuit; and a weight mounted on the free end of at least one of the two piezoelectric sensors is ground so that the levels of the two measured signals and the difference therebetween become small,  Thus, acceleration components applied to the spinning piezoelectric beam, in the detected voltages of the two piezoelectric sensors, are rendered to have the same phase and the same amplitude.  On both sides of each piezoelectric sensor there are formed electrodes which are spaced 1.5 times the thickness of the sensor from support washers.

Abstract: A frequency modulator is formed in a monolithic integrated circuit as a whole.  A direct current signal from a center frequency control circuit and an alternating current signal from a voltage controlled amplifier (VCA) which receives a modulation signal and outputs the alternating current signal are applied to a control input of a voltage controlled oscillator (VCO).          A center frequency (Fo) of the VCO is determined by the direct current signal from the center frequency control circuit and a frequency deviation amount (.DELTA. f) of the VCO is determined by the alternating current signal from the VCA, and therefore, a frequency-modulated signal of Fo +          .DELTA. f can be outputted from the VCO.  The direct current signal from the center frequency control circuit is also applied to a control input of the VCA, and therefore, the center frequency of the VCO as well as an amplitude of the alternating current signal, that is, the frequency deviation amount can be controlled by only the direct current signal.

Title: Electrolytic method for coloring anodized aluminum
Inventor: BENITEZ-GARRIGA ELISEO
IPC: C25D11/22
Filed: 1990-08-17
Abstract: WAX/dpv 1736a ABSTRACT     The invention provides an improved electrolytic process for producing anodized metal substrates such as aluminum or aluminum alloys colored using optical interference effects.  In particular, the invention pertains to a novel electrolytic method of modifying the anodic barrier layer.  The method results in all colors of the visible spectrum Without the need for anodizing in a separate phosphoric acid-based electrolyte.    The modification procedures consists of treating the metal substrate with a sequence of direct and alternating currents. The alternating current is symmetrical, the voltage of the positive half-wave equal to that of the negative half-wave.          A preferred red sequence is direct current, alternating current, direct current.  As a result, metallic oxide is deposited within the enlarged pores to a defined height, thus achieving the decomposition of light and obtaining the different colors of the visible spectrum. The modification step can be performed in the anodizing bath, the electrocoloring bath, or in a specific bath with an acid electrolyte.

Inventor: MECCARIELLO THOMAS V
IPC: H05G1/46

Abstract: The brightness of an X-ray video image during fluorography is maintained at a substantially constant level by a control circuit which varies the X-ray dose in relation to changes in the average brightness of the X-ray image. As the X-ray system approaches the limits of its imaging capability, varying the X-ray dose alone may not yield the desired brightness level. At this point, the gain applied to the video signal is increased to improve the brightness. A linear brightness taper function is used such that, as the level of video gain required to maintain constant brightness increases, the actual video gain increases by a smaller proportional amount. This function results in the brightness of the video image decreasing somewhat as the video gain is required to provide a greater degree of brightness compensation. This reduction in brightness not only provides a visual indication to the image observer that the system is approaching the imaging limits, but also creates an illusion that noise artifacts in the image are not intensifying as the video gain increases.
