Abstract: Prior engine ignition systems for a multicylinder spark ignited engine have been too complex and have incorporated external wiring cables and a plurality of transformer assemblies that placed the individual primary and secondary coils thereof in an external location for better heat dissipation. Thus the cable and transformer assemblies were subject to damage by personnel working on the engine. These problems have been overcome by the engine ignition system (8) including a transformer assembly (10) having an elongate body (68) including a cup portion (70) containing the coils (82, 84), a base portion (72), and a stem portion (74). A conducting core (96) extends through the stem and base portions and a suitable clip (116) connects the core electrically to a spark plug (30) installed in a profiled bore (28) of the cylinder head (24). A position device (130) is provided to positively align and contain the transformer assembly (10) within a valve mechanism compartment (149) defined between the cover (148) and the cylinder head (24), and including a spring member (132) connected to the cup portion (70) and depending guide members (150) formed within the cover (148) that cooperate with each other.

Abstract: An electronic control (31) is provided for a vehicle (10) having an engine (12), a main drive (14) driven by the engine (12), a fluid pump (36) driven by the engine (12) for providing pressurized fluid, and a supplemental drive driven (30) by the pressurized fluid. The electronic control (31) includes a main drive sensor (54) for sensing the speed of the main drive (14) and responsively producing a main drive speed signal. A vehicle speed sensor (64) senses the speed of the vehicle (10) relative to the ground and produces a vehicle ground speed signal. A pressure sensor (74) senses the pressure of the pressurized fluid supplied to the supplemental drive (30) by the pump (36) and responsively produces an actual pressure signal. A processor (52) receives the main drive speed, vehicle ground speed, and actual pressure signals, produces a slip ratio signal responsive to a ratio of the main drive speed and vehicle ground speed signals, produces a desired pressure signal responsive to the slip ratio signal, produces an error signal responsive to a difference between the desired and actual pressure signals, and controls the fluid pressure in the supplemental drive (30) in response to the error signal.

Abstract: An encapsulated piezoelectric solid state motor stack (100, 200) having a plurality of piezoelectric disks interleaved with a plurality of electrodes (102, 202). A first elastomer (220) is used for encapsulating the stack to prevent arc-over. A second elastomer (224) is used for encasing the combination of the encapsulating elastomer and the stack. An elastomer grease (222) is sandwiched between the encapsulating elastomer and the encasing elastomer for reducing friction between the combination and the encasing elastomer. The friction is induced by an axial displacement produced between first and second end sufaces of the stack when the electrodes are biased by a source of electrical potential. The structure also includes a protective housing (104, 204) including a diaphragm (118). The housing (104, 204) cylindrically encases the combination of the stack (102, 202), the encapsulating elastomer (220), the elastomer grease (222) and the encasing elastomer (224), and the one end thereof. The diaphragm (118) is attached to the housing (104 and 114) for encasing the other end of the combination.

Abstract: A gas sampling device (10) includes a dilution tunnel (12) of particularly effective construction that reduces contamination or soiling of the ducting leading to a filter assembly (66) and improves the accuracy of the results. The gas sampling device (10) has a sampling probe (56) disposable in the gas stream (64) of an engine (95) or the like, and a controlled source of clean and pressurized diluent air (36). The dilution tunnel (12) includes an air distribution tube (14) defining a plurality of distribution holes (18) therethrough, a collar (30) defining a first annular chamber (28) about the air distribution tube (14) that is connected to the air source (36), and a porous center tube (48) having a plurality of micron-sized pores (50) connected between the sampling probe (56) and the filter assembly (66). A second annular chamber (47) is defined between both tubes (14, 48), and the diluent air supplied thereto is uniformly passed through the porous center tube (48) to effect good mixing of the exhaust gas and diluent air while providing a boundary layer of diluent air that keeps the center tube (48) clean. An alternate embodiment gas sampling device (10') employing master and slave mass flow controllers (80, 82) is also disclosed.

Abstract: An idler wheel assembly (10) for supporting and guiding an endless track chain assembly of a track-type vehicle includes a spoked idler wheel (11) having a plurality of aligned apertures (20, 22) through the sidewalls (16, 18). A resilient plug assembly (24) is contained within each set of aligned apertures (20, 22). A resilient pad (30) isolates each plug assembly (24) from the idler wheel (11). Conventional spoked idler wheels have a plurality of holes through the sidewalls. These holes collect debris which can damage the idler wheel or other undercarriage components. The subject idler wheel assembly (10) includes resilient plug assemblies (24) to close the apertures (20, 22) and maintain the sound reducing characteristics of the idler wheel assembly (10).

Abstract: Systems for teaching a robot (12) to perform a desired function are useful in many applications. Advantageously, such teach systems may be operated without special training. The subject teach system senses forces and torques being applied to an end effector (16) by an operator. A move signal is created which causes the robot (12) to move the end effector (16) in the direction of the applied force or torque and at a seped being reflective of the magnitude of the applied force or torque. Reference positions are stored in a memory device as the robot (12) moves the end effector (16).

Abstract: In many applications, it is important to measure and display payload weight for a loader vehicle. The subject apparatus and method senses only the hydraulic pressure of a lift cylinder. The payload weight is computed by curve fitting the sensed cylinder pressure to a second order time dependent polynomial and comparing the time dependent polynomial to one of a series of predetermined second order geometric polynomials. The weight computation algorithms used in the payload monitor are applicable to a number of work vehicles having at least one work implement linkage and at least one hydraulic cylinder for modifying the linkage geometry.

Abstract: Conventional tappet retainer assemblies for a fuel injection pump typically include a blind radial passage formed in a tappet. Only one opening in the passage is available for inserting and removing a ball bearing or spring and stop pin which must be held in place before the tappet is inserted in a housing bore. In such an arrangement, the ball bearing or compressed spring and stop pin are prone to pop or fall out before the passage opening is closed by an internal wall of the housing bore. The present invention provides an improved tappet retainer assembly (10) which includes a housing (16), a tappet (18), a stop device (22), and a biasing device (24). The tappet (18) includes an internal passage (44) which allows the stop device (22) and biasing device (24) to be communicated to their final assembled position in the internal passage (44) while the tappet (18) is already inserted in a bore (28) of the housing (16).
