Title: Method and apparatus for dissociating ions by electron impact
Inventor: VESTAL MARVIN L
IPC: H01J49/14
Filed: 1987-10-14
Granted: 1990-12-04
Abstract: TITLE: METHOD AND APPARATUS FOR DISSOCIATING             IONS BY ELECTRON IMPACT                  ABSTRACT OF THE DISCLOSURE         Improved methods and apparatus suitable for use in mass spectrometry are provided for dissociating ions by achieving electronic excitation of the ions using electrons.    In MS-MS applications, ion dissociation is induced by electron impact on an ion beam after the beam has exited a first mass analyzer, and before the beam enters a second analyzer.  An efficient method for dissociating ions is achieved by providing a low velocity ion beam traveling substantially along the axis of an RF excited multipole field, and intersecting sheet electron beams traveling transverse to the axis of the field.          When used in the analysis of high molecular weight, nonvolatile molecules, the teachings of the present invention yield the extensive and reproducible fragmentation characteristics generally associated with electron ionization of lower mass, volatile molecules.  The methods and apparatus of the present invention may therefore be used in conjunction with mass spectrometry to qualitatively and quantitatively analyze a significantly greater quantity of samples.  The techniques of the present invention are also well suited for dissociating high-mass, even-electron ions produced by thermospray and other soft ionization techniques.

Title: Laser temperature controller
Inventor: KOLLANYI MIKLOS J
IPC: H01S5/024
Filed: 1987-11-19
Granted: 1991-11-12
Abstract: LASER TEMPERATURE CONTROLLER  ABSTRACT OF THE INVENTION A laser temperature controller is disclosed for controlling the temperature of a laser device.  The controller includes a bridge circuit connected to a thermistor device which is mounted on the laser package.  The bridge circuit generates error signals representing a need for cooling or heating as the operating temperature of the laser rises or falls about a set threshold.  A voltage conversion circuit converts the error signals to a positive or negative polarity voltage,  The output of the voltage conversion circuit is applied to a pair of operational amplifiers which input the voltage and compare it to a set reference voltage.  When cooling is required a first amplifier provides a biasing voltage to a transistor when a set threshold is exceeded.  The associated transistor switches drive current to a thermoelectric device mounted on the laser package thereby, cooling the laser.  Similarly, when heating is required a second amplifier and transistor switches current of an opposite polarity to the thermoelectric device, which heats the laser.  The output signal from the voltage conversion circuit is also applied to a laser temperature alarm circuit which provides a visual indication and an alarm signal to a controller interface when a set threshold of laser temperature is exceeded.

Granted: 1992-11-24
Abstract: "IMPROVED ARC WELDING SYSTEM"                Abstract of the Disclosure An improved electronic welding station is disclosed. The welding station provides for an improved arc striking capability by providing a higher arc striking voltage and a large arc striking current and, once the arc is struck, automatically switches over to preselected parameters for conducting the welding operation. Also disclosed are a method for preventing transistor failure due to loads which tend to cause a very large instantaneous current flow and an apparatus for protecting the driver circuit and the remaining output transistors in the event that one of the output transistors should suffer a collector-to-base short. The welding station also describes a method of operating the cooling fan at a speed commensurate with the cooling requirements and periodically reversing the voltage to the cooling fan so as to extend the operating lifetime of the fan brushes. The welding station also has several shutdown circuits which protect the components of the welding station in the event of cooling fan failure or excessive heating of the weld station. The welding station also provides for a shutdown period for cooling off in the event that the maximum allowable instantaneous current is exceeded.

Abstract: ABSTRACT OF THE DISCLOSURE An electromagnetic contactor is taught having an E-shaped movable  magnetic  armature  and  a  complementary E-shaped  permanent  magnet.   The  outboard  legs of  the E-shaped members abut at closure.  Each of the central legs of  the  complementary  magnetic  members  have  significant magnetic material  removed from the face thereof leaving complementary abutting nipples or protrusions which mate or make with each other as the outer legs make or mate with each other.  The total reluctance of the magnetic system when in the abutted state is significantly lower than if the air-gap material had not been removed.  This allows the kickout  spring  to  operate effectively  to  separate  the magnets at an appropriate time.  The lower  the magnetic reluctance the higher the residual magnetism and the more difficult it is for the kickout spring  to  separate  the magnetic members and thus the contacts of the contactor during an opening operation.  The central nipple portions or protrusions abut against each other to prevent longitu-dinal movement of one magnetic central leg member relative to  the  other.   This  reduces  wear  and noise.   This  is particularly important when the magnets are maintained in the closed state by the utilization of an assisting HOLD pulse which is continuously supplied to the electromagnet.

Title: Method of measuring quantity of heat applied to optical fiber
Inventor: ONODERA TSUTOMU
IPC: G01K11/00
Filed: 1988-12-13
Granted: 1993-04-27
Abstract: Abstract of the Disclosure In a method of measuring a quantity of heat, the distance between the position of an end of an exposed fiber portion before heating and the position of the end after heating is measured, and the quantity of heat applied to the end of the exposed fiber portion is calculated based on the distance.  When heat is applied to an end of an exposed fiber portion, the end is fused and is rounded due to surface tension.  For this reason, the position of the end of the exposed fiber portion retracts from the position it occupied before heating by the volume required for rounding the end.  This retraction amount corresponds to a quantity of heat applied to the end of the exposed fiber portion.  There-fore, by measuring the retraction amount, the quantity of heat applied to the ends of the exposed fiber portion can be quantitatively measured.

Abstract: ABSTRACT OF THE DISCLOSURE An attachment for supersonic thermal spray equipment by which inert shield gas is directed radially outwardly about the central core of a supersonic, particle-carrying flame to isolate the same from ambient atmosphere.  The shield gas is injected tangentially against the inner sur-face of a constraining tube attached to and extending from the discharge end of the thermal spray gun nozzle, causing the shield gas to assume a helical flow path which per-sists until after it exits the tube and impacts the work piece.  A process using the shielding apparatus with a high-velocity, thermal spray gun and employing oxygen and hydrogen as gases of combustion and inert gas to introduce metal powder, having a narrow particle size distribution and low oxygen content, into the high-velocity combustion gases, produces significantly improved, high-density, low-oxide metal coatings on a substrate.
