Patent number: 4498625Abstract: A unit fuel injector combines an injection nozzle, a fuel pumping unit, and a solenoid valve with a mechanism for precise adjustment of the air gap size in the solenoid. Activation of the solenoid and closing of the spill port in the solenoid valve results in fuel injection from the injection nozzle. Controlling the duration and timing of the solenoid voltage pulse controls the quantity of fuel injected and injection timing, while an adjustment of the size of the solenoid air gap permits fine adjustment of the quantity of fuel injected at a given voltage pulse duration. Adjustment of the air gap size in the solenoid for the unit fuel injector uses a differential thread arrangement. Relative rotation takes place between two pairs of threads so that the accuracy of adjustment is determined by the difference between the pitches of the two pairs of threads.Type: GrantFiled: June 27, 1983Date of Patent: February 12, 1985Assignee: Ford Motor CompanyInventor: Michael M. Schechter

Patent number: 4489293Abstract: A ceramic resonator element having high Q, high dielectric constant, and a low temperature coefficient of resonant frequency is enclosed within a cavity to form a composite microwave resonator having reduced dimensions and weight as compared to a simple cavity resonator. A pair of tuning screws extend into the cavity along orthogonal axes to tune the structure to resonance along these axes at frequencies near the fundamental resonance of the ceramic element. Several such cavities can be formed in a short length of waveguide by the use of transverse partitions at spaced intervals and coupling between cavities can be accomplished by using simple slot, cross or circular irises. In each cavity, a mode-perturbing screw is positioned along an axis 45.degree. from each of the orthogonal tuning screws, such that resonance along either of the orthogonal axes is coupled to excite resonance also along the other.Type: GrantFiled: February 14, 1983Date of Patent: December 18, 1984Assignee: Ford Aerospace & Communications CorporationInventor: Slawomir J.

Patent number: 4483065Abstract: Disclosed is a seal which provides effective hermetic sealing of insulated metallic feedthroughs in metallic containers. The device has particular applicability in the fabrication of pressurized metal/gas battery cells such as those used in spacecraft. A conductive terminus protrudes through a metallic vessel which may be pressurized. It is desired to maintain electrical separation between the terminus and the wall of the vessel by means of a dielectric, which is compressed between the terminus and a metallic boss to provide a hermetic seal. The compressive force is applied radially outwardly by means of drawing a nondeformable pin through a hollow cylindrical barrel constituting the terminus, thereby slightly deforming the barrel and grossly deforming the dielectric. The pin may be either pulled out of the barrel from within the vessel or pushed into the barrel from outside the vessel, but in each case force is applied radially outwardly in a gradual, relatively frictionless fashion.Type: GrantFiled: November 29, 1982Date of Patent: November 20, 1984Assignee: Ford Aerospace & Communications CorporationInventors: Theodore O. Meyer, Gerrit van Ommering

Patent number: 4473796Abstract: This circuit measures both the resistance and the capacitance of the parallel RC circuit that is the equivalent of any substantially non-inductive two-port device. Thus, the circuit can measure any resistance, capacitance, RC network, or diode, including photovoltaic diodes. The invention uses an operational amplifier, an audio A.C. oscillator and a voltage measuring device such as a digital RMS voltmeter. The resulting apparatus is small, inexpensive, accurate, and easy to operate. The resistance is measured with the audio oscillator set for a low frequency (such as 70 Hz); the capacitance is measured when the audio oscillator is set at a high frequency (such as 20 KHz). The resultant values can either be calculated using simple formulas or can be displayed directly using an analog or digital circuit.Type: GrantFiled: June 18, 1982Date of Patent: September 25, 1984Assignee: Ford Aerospace & Communications CorporationInventor: Donald B.
