Abstract: A cable joining assembly (20) for easily joining push-pull and torsional cables by a hand assembly operation and without the use of tools is disclosed as comprising a first conduit section (22) and a second conduit section (26). First and second slide wires (24, 28) are relatively movable within respective first and second conduit sections (22, 24). A snap-together mechanism (30) joins the sectins as the relative movement of the first and second slide wires (24, 28) is affixed with respect to the first and second conduits (22, 26) respectively and by joining the first and second conduit sections (22, 24) simultaneously connecting the first and second slide wires (24, 28). Unfixing the relative movement of the slide wires (24, 28) with respect to the conduits (22, 26) allows the slide wires (24, 28) to be movable together and transmit forces thereby within the formed composite conduit.
Abstract: A coupling (10) is disclosed for joining together a first tube (12) and a second tube (14) to form a continuous fluid passageway. The first tube (12) has a mount (20) a predetermined distance from its end (18) and the second tube (14) has a return bend on its end (36). Second tube (14) telescopically fits over first tube (12). A cage (22) having inclined locking tabs (30) is mounted by mount (20) externally of first tube (12). Locking tabs (30) cam to allow the return bend (36) of second tube (14) to pass the locking tabs (30). Tabs (30) return to their at rest inclination after the return bend (36) passes, to trap the return bend (36) between the locking tabs (30) and mount (18), thereby locking the first and second tubes (12,14) against disconnection and providing a visible connection to allow verification of the connection.
Abstract: This specification is directed to a UV-base ceramic paint composition and a method of forming a glass sheet with a UV-base ceramic paint thereon. The method has the following steps. A UV-base ceramic paint is applied to the glass sheet. The UV-base ceramic paint includes selected ceramic paint components along with, as a new component thereof, finely divided zinc metal powder. The glass sheet is subjected to UV radiation and then heated to a temperature which softens the glass sheet sufficiently so that the glass sheet can be formed. The glass sheet and the ceramic paint thereon are engaged with a fiberglass covered forming die to form the heated glass sheet to a desired shape. The forming die is removed from engagement with the glass sheet. The finely divided zinc metal powder addition to the ceramic paint is credited with being effective to prevent sticking of any of the ceramic paint to the forming die. The glass sheet is cooled to obtain a formed glass sheet with a ceramic paint thereon.

The front and rear tape drives 46 and 48 are routed through front and rear tape channels 66 and 68.
Abstract: The invention relates to an internal combustion engine wherein two intake tracts 12, 14 balanced for equal air flow, lead to each intake valve and both tracts have outer sections which open on to the same side face of the engine, the inner sections of the tracts having axes which lie in a common plane containing the axis of the valve and the inner sections of the tracts being substantially symmetrical about the valve axis.
Abstract: A mechanism is described for achieving variable lift of a valve of an internal combustion engine having an overhead camshaft disposed above the valves. The mechanism comprises two levers both pivoted about fixed fulcrums and a coupling member which is movable along overlapping arms of the two levers to vary the mechanical advantage and thereby vary the valve lift in dependence upon the position of the coupling member.
Abstract: A repetitive spark distributorless ignition system stops ignition current before the complete discharge of magnetic energy in the ignition coil supplying the spark plug. The ignition coil is then recharged so an additional spark can be applied to the spark plug.
Abstract: Stall current levels are determined according to measured peak currents occurring immediately after the energization of a motor. By utilizing a fractional value of the determined peak current value, the stall current is determined each time the motor is energized to compensate for variations in current flowing in a motor at different ambient temperatures.

Abstract: A valve train for an overhead camshaft type engine includes a finger follower lever type rocker arm assembly. The lever is of lightweight stamped construction containing a pocket or recess in which is received a precision molded plastic bearing cup. The cup has a smoothly polished bearing surface for slidably receiving an axleless roller that is contained laterally within the insert and is rotated by the engine driven cam located above the roller for pivotally moving the lever to actuate the engine valves. The inclusion of the pocket in the lever assures lubrication of the parts at all times since it will collect and retain lubricant or engine oil during engine operation so that even during a lengthy shutdown, upon restart, the elements will be fully lubricated.
Abstract: A hybrid air charge calculation system for an internal combustion engine in which the air charge is obtained by using either the mass airflow sensor readings or the engine speed and throttle angle information. A decision logic selects either means based on the engine speed, throttle angle, and the mass airflow rate.
Abstract: A throttle valve for an internal combustion engine in which a flow path is defined between a central core and a tube having a resiliently flexible wall, which tube separates the flow path from an adjacent working fluid chamber, whereby changes in the pressure within the chamber cause deformation to the tube wall resulting in changes in the tube cross-section between a wide open throttle position and a valve closed position, the flexible wall tube being designed to take up a valve closed position when the pressures on its opposite sides are equal, with the flexible wall tube being uniformly cylindrical in its relaxed state.
