Title: Multi-burner gas control apparatus
Inventor: BERLINCOURT DON A
IPC: F23N5/20
Filed: 1990-03-14
Granted: 1996-09-10
Abstract: Gas  control apparatus to regulate the flow of gas to a plurality  of  burners is disclosed.  The apparatus permits a main  gas  solenoid valve to be actuated for a pre-determined period  of  time  allowing the burners to be ignited.  If the burners  are  not ignited within the pre-determined period of time,  the  main  gas  solenoid  valve  is  deactuated.  Even though  a  main  gas solenoid valve is utilized, each burner can  be separately ignited by means of a start signal applied thereto.   After  ignition,  the main gas solenoid valve will remain  actuated  only  if  a flame is present at the ignited burner  and  a  start  signal  is  applied  to  the remaining burners.

Abstract: An object (14) which is to be implanted with ions is enclosed in a container (12).  A plasma (44) is generated in a chamber (26) which is separate from, and opens into the container (12).  The plasma diffuses from the chamber (26) into the container (12) to surround the object (14) with uniform density.  High voltage negative pulses are applied to the object (14), causing the ions to be acceler-ated from the plasma (44) toward, and be implanted into, the object (14).   Line-of-sight communication between a plasma generation source (30) located in the chamber (26) and  the  object  (14)  is  blocked,  thereby  eliminating undesirable effects including heating of the object (14) by the  source  (30)  and  transfer  of thermally  discharged material from the source (30) to the object (14).  Two or more  chambers  (26,34)  may be provided  for  generating independent plasmas (44,46) of different ion species which diffuse into and uniformly mix in the container (12).  The attributes of the different plasmas (44,46) may be individ-ually selected and controlled in the respective chambers (26,34).

Granted: 1995-11-07
Abstract: There is disclosed a method for automatically adjusting a dispensing tip from a surface onto which liquid is to be dispensed, a proper distance that precludes the dispensing stream from puddling up, or from breaking apart.  The method features the formation on the tip of a meniscus of a nominal small volume and advancing the tip and meniscus until the surface is contacted.  The resulting decrease in pressure in the tip is measured, to trigger the tip to stop its advance and to start dispensing.  In circumstances wherein the contacted surface is hydrophobic so as to ideally require a meniscus depth greater than the nominal depth, the tip is retreated from the surface, during dispensing, to the ideal depth.

Granted: 1998-07-21
Abstract: A method of and apparatus for recording information from a master medium onto a slave medium. In one embodiment, digital information on a master medium is reproduced and stored at a first rate, typically at real time, in a first high speed digital storage device such as a magnetic disk drive. The digital information stored in the first storage device, when needed, is transferred at a second rate, much higher than the first, to a second digital storage device in which it is stored until it is scheduled for duplication, at which time the digital information is repeatedly played back at a third rate, much higher than the first rate and slower than the second rate, is converted from digital information into analog information and applied to a duplicating device for recording the analog information onto a slave medium. Because the information stored in the first digital storage device is not directly used in production, the duplicating device can be duplicating information previously transferred from the first storage device to the second at the same time information is being reproduced from a master medium and loaded, in real time, into the first storage device.
