Patent CA-2089314-A1 (CA)
Title: Arc discharge lamp containing mechanism for extinguishing arc at end-of-life
Inventor: PAI ROBERT Y
IPC: H01J61/70
Filed: 1993-02-11
Abstract: ABSTRACT     An  arc  discharge  lamp  having  an  end-of-life structure   and   including   a   light-transmissive envelope having a tubular-shaped main body and  a press seal disposed at each end of the main body. An  electrode  filament  having  a  pair  of  ends  is located in each end of the envelope.  Each electrode filament end is in a contiguous relationship with an inside surface of the lamp envelope.  When one of the    electrode    filaments    is  depleted    of electron-emissive material, increased heating of the electrode filament caused by an increase in cathode fall voltage, produces a localized hot spot on the internal  surface of the envelope.   This  localized heating causes a puncture in the lamp envelope and evacuation  of  the  lamp.    The  introduction  of external atmosphere into the lamp extinguishes the arc discharge and renders the lamp inoperable.

Title: Methods of conditioning fluid in an electronically-controlled unit injector for starting
Inventor: AUSMAN THOMAS G
IPC: F02M59/46
Filed: 1991-12-23
Abstract: Herein are disclosed methods of conditioning fluid, such as damping fluid, in an electronically-controlled unit injector (18) in order to facilitate quick starting of an engine (12). Fluid normally used to dampen the motion of an electrical actuator assembly (36) of the unit injector (18) can remain in the actuator assembly (36) after the engine (12) is stopped. If too much fluid remains and cools off in the actuator assembly (36), quick starting of a cold engine may be hindered. Each of the above methods expels and/or heats up at least a portion of the remaining fluid in the actuator assembly (36) while the engine (12) is at rest and thereby enables quicker response of the actuator assembly (36) when the engine (12) is started. Such quicker response improves the fuel injection delivery capability and timing accuracy of the unit injector (18) during engine startup.

Abstract: MULTIPIECE GIMBAL                 ABSTRACT OF THE DISCLOSURE        A  gimbal  (22)  with three critical dimensions is    prepared   by   separately   fabricating   three components  of  the  gimbal (22), and then joining the components  on  tooling.    The  steps  of  the method include  fabricating  a  base ring platform (50) while maintaining  a platform height critical dimension, and fabricating  two  brackets (56), while maintaining the bracket pivot  bore  height  as a critical dimension. The  gimbal  (22)  is completed by assembling the base ring  platform  (50)  and  the  two brackets (56) on a tool  base  with  an arbor extending between the pivot bores  (26)  on the brackets (56), while maintaining a bracket  separation  critical  dimension,  and rigidly fixing   the  two  brackets  (56)  to  the  base  ring platform   (50)   with locating  pins  (64).    Three critical   gimbal  dimensions  are  thereby  obtained, while    reducing   the   cost   and   complexity   of fabrication.

A spindle has a front end that is provided with a tap and that extends through the gate and into the guide channel. An end seat is disposed adjacent to the rear end of the machine base and is formed with an axial passage that is aligned axially with the spindle. The end seat has a front end that is provided with a rotatable chuck. A push rod is extended into the guide channel via the open front end so as to push the nut blank toward the spindle and so as to push the spindle to extend into the chuck in order to enable the latter to clamp releasably and drive rotatably the spindle to commence threading of the nut blank. The push rod is retracted from the guide channel after threading of the nut blank to produce a formed nut has been accomplished. A push pin is employed so as to push the spindle away from the chuck and cause movement of the formed nut from the spindle to the push pin, and is retracted into the axial passage so as to remove the formed nut therefrom.

Filed: 1994-06-22
Abstract: In a fluid valuing system, binary fluid control lines are connected in parallel between a common fluid inlet and a common fluid outlet. Each line has a binary valve and a metering orifice for passing a predetermined rate of fluid flow. The rates are in a geometric progression in factors of two. An analog fluid control line is connected in parallel with the binary lines, and has a continuously adjustable flow rate regulator for passing any selected rate of fluid flow up to a maximum at least equal to the largest increment of rate change in the binary lines. The regulator is formed of a miniature solid state device. A controller sets each binary valve open or closed, and sets the regulator for a selected flow rate, such that cooperative settings provide for a smoothly variable rate of total fluid flow.
