Abstract: New nickel-base superalloys with good overall properties, the alloys being particularly adapted for high temperature applications at about 1800.degree. F. to 2000.degree. F., such as for turbine engine or other high temperature, high stress applications, and possessing a complex, multi-component gamma prime Ni.sub.3 Al.sub.1 matrix (not necessarily in the exact 3:1 proportion) in which both the nickel and aluminum atoms are partially replaced by, and/or containing, one or more of the following alloying elements: Cr, Ti, Co, Mo, Ta, W, C, Cb, Be, B, Zr and rare earths, such as for example, mischmetal. The gamma prime Ni.sub.3 Al.sub.1 matrix phase precipitates a delta Ni.sub.1 Al.sub.1 phase (not necessarily in the exact 1:1 proportion) at elevated temperatures (termed herein "inverse precipitation") thus providing critical high temperature strengthening of the matrix. Additionally, the alloy structure contains a fairly large quantity of carbides, some borides and some nitrides.

Abstract: A throttle body assembly comprises a throttle body having an induction passage therein with a pair of rotatively coupled, parallel shafts extending across the induction passage. A pair of blades are affixed to each shaft with each blade comprising a main blade section for selectively restricting the induction passage in accordance with shaft rotation and an auxiliary blade section which presents a curved confronting surface to an adjacent wall portion of the induction passage so as to preclude intrusion of any appreciable amount of induction air between each blade and the corresponding wall portion over the operative rotational range of the shafts.

Abstract: An electronic engine spark timing controller contains a throttle position transducer circuit and an intake manifold vacuum transducer circuit which provide respective signals representing the throttle position and the magnitude of intake manifold vacuum. Each of these two circuits contains a novel configuration of electronic circuit elements to develop an output electrical waveform composed of repetitive pulses each of which has a pulse width representative of the corresponding mechanical input signal which is supplied to the circuit via a transducer in the form of a coil whose inductance is varied in accordance with the mechanical input signal. The coil in each transducer circuit forms a portion of an RL type monostable circuit which exhibits an electrical transient when triggered. Both transducer circuits are triggered from a free-running pulse generator which is set to generate pulses at a fixed frequency.

Abstract: A relay adapter circuit is electrically connected with the existing stop lamp and turn signal lamp systems of a motor vehicle and with the existing lamps on a trailer towed by the motor vehicle. The adapter is especially suited for installation where the vehicle has separate stop and turn signal lamp circuits on each side of the vehicle and the trailer has only a single lamp circuit on each side. The adapter achieves combined stop/turn signal capability in the trailer lamps.

Abstract: In one embodiment, a circuit parameter of a sensor varies in accordance with an input useful in controlling an event associated with operation of an engine, for example, spark timing. The sensor is connected in an input sensing circuit characterized by a first order differential equation exhibiting an exponential transient whose time constant is representative of the circuit parameter, and hence of the input being sensed. A step function input is applied to the sensing circuit to cause the occurrence of an exponential transient, and concurrently a digital counter circuit begins counting clock pulses. The transient is compared against a predetermined reference, and when a predetermined relationship between the reference and the transient is attained, the counter circuit ceases counting pulses. The accumulated count is in the form of a binary word which may be used directly by a digital microprocessor in calculations for controlling the event.

Abstract: A variable inductance transducer for providing, via inductance modulation, an electrical output signal which is representative of a mechanical input signal. The transducer comprises a cylindrical plastic bobbin on which an inductive coil is wound. A pair of electrical terminal receiving sockets for a pair of electrical terminals are formed at one end of the bobbin and a pair of electrical terminals are disposed therein. The ends of the wire forming the coil are soldered to the terminals. A protective enclosure is molded around the coil and the portions of the terminals received in the sockets to enclose the coil and lock the terminals in place in the sockets. A ferrite core is slidably arranged within a central axial bore in the bobbin to vary the inductance of the transducer in accordance with the axial portion of the core.

Abstract: A swirler for a fluid flowmeter comprises a plurality of axially and circumferentially overlapping swirl blades within a flow conduit which impart a swirling motion to fluid passing therethrough. The swirler is constructed of a first element containing selected ones of said blades which are circumferentially non-overlapping and a second element containing the remaining blades which are also circumferentially non-overlapping; the two elements are assembled so as to bring the blades of each element into overlapping relationship with those of the other element.

Abstract: A variable inductance transducer for providing, via inductance modulation, an electrical output signal which is representative of a mechanical input signal. In a preferred embodiment the mechanical input signal is the intake manifold vacuum of an internal combustion engine and the electrical output signal is utilized in an engine spark timing control system to adjust the spark timing in accordance with the intake manifold vacuum. The transducer comprises an actuating mechanism in the form of a vacuum servo which axially positions a ferrite core within a central axial bore of a plastic bobbin on which an inductive coil is wound to thereby vary the inductance of the coil in accordance with the vacuum applied to the servo. The bobbin and coil are enclosed in plastic to form a separate unit which is assembled into the transducer by being controllably lodged within the bore of a molded plastic element forming a portion of the body of the transducer.

Abstract: A speed sensor comprises a pick-up device mounted on the aluminum casing of a vehicle transmission, adjacent an existing ferromagnetic gear inside the transmission casing, which gear rotates in unison with the driven wheels of the vehicle. The pick-up device comprises a permanent magnet and a toroidal ferromagnetic core on which an inductive coil is wound. The permanent magnet and toroidal core are cooperatively arranged with respect to the ferromagnetic gear such that a magnetic circuit is created from the permanent magnet through the toroidal core, through the transmission casing, and through the ferromagnetic transmission gear back through the transmission casing to the permanent magnet. As the gear rotates, the reluctance of the magnetic circuit is varied at a rate representative of the speed of the gear and hence the speed of the vehicle. The speed information is provided across the inductive coil.

Abstract: An automobile engine driven fuel pump operates to cause alternate fuel pumping and fuel vacuum cycles in a fuel pumping chamber and concurrent alternate air vacuum and air pumping cycles respectively in an air pumping chamber and also to maintain a normally closed fuel control valve open in the fuel supply conduit to the pump during the fuel vacuum and air pumping cycles completely independently of the fuel pumping cycles. If the engine stalls, as for example in the event of a collision or automobile roll-over, the pump will stop and the control valve will close to prevent fuel leakage from the supply conduit. Pressure in the supply conduit also urges the control valve to its closed position.
