Abstract: APPARATUS AND METHOD FOR SHORT-ARC WELDING                 Abstract In a short circuiting arc welding apparatus and method wherein a continuously fed welding wire alternates between an arcing condition during which the wire is spaced from the molten pool of the workpiece and a short circuit condition during which the melted metal on the end of the welding wire is in contact with the molten metal pool and thereafter transfer to the workpiece by a necking action breaking the melted metal from the wire, there is provided an improvement including providing a first high inductance current control circuit for continuously directing a low level, arc sustain-ing, backgroung current between the welding wire and She workpiece and providing, a second current control circuit for controlling current flow during the arcing condition of the process. This second current control circuit includes time delay means for causing the initiating, arc at the start of the arcing condition to have an area determined primarily by the background current for a preselected time during which the molten metal on the tip of the welding wire and in the molten metal pool are drawn, by surface tension, to the wire and pool respectively, is essentially quelled and means for then passing a high current pulse through the arc between she wire and pool with a preselected energy for melting a relatively constant volume of metal on the end of the wire and space from the pool. This high energy pulse is near the start of the arcing condition and terminates generally be-fore the mid-point of the arcing condition so that the wire is first melted and then driven into the molten metal pool after the pool has essentially quelled or become quiescent.

Abstract: MULTIPLEXED ADDRESS CONTROL IN A TDM COMMUNICATION SYSTEM         ABSTRACT OF THE DISCLOSURE    A  message communication system employing  one or  more centralized  communication  stations  transmitting  messages through  Earth  orbit relay satellites to  mobile  receivers utilizing  Time  Division  Multiplexed  (TDM)  communication signals  having signal time frames divided into a series  of transmission  channels.   A  predetermined  number  of   the channels  are  designated  as  address  channels  with   the remainder   being  used  for  data  transfer.    Information transmitted on the address channels is used by receivers  to determine   both   the  presence  of  a  message   and   its corresponding   data  transmission  channel.   Each   system receiver  scans, and tracks only the  communication  signal address channels until a message addressed to that  receiver is  detected,  at which time the selected  receiver  changes channels to the designated data channel for reception of the message.   Thus,  demodulation of the  entire  communication signal  is  not required and processing time  and  power  is reduced for the typical waiting condition when messages  are not being received.  While a message is being received  only a  portion  of the communication signal  need  be  received, demodulated  and  decoded. The  decoded  message  is  then displayed  on  a display screen or similar  device  for  the recipient.     [2536MPA4.All]

Abstract: This invention relates to an enzyme assay for qunatita-tive analysis of biochemical substances using NAD(P)-NAD(P)H system and utilizing hydrogen peroxide, in which isocitric acid, metal ions and isocitrate dehydrogenase are previously added to a test sample, thereby consuming the endogenous  substances that interfere the analysis, and at the same time regenerating NAD(P)H reduced.  The isocitrate dehydrogenase is then inactivated by addition of a chelating agent, an enzyme or substrate that generates hydrogen peroxide as reaction product is added simultaneously  or thereafter, and the amount of hydrogen peroxide thus formed is measured.    Biochemical substances that generate hydrogen peroxide as reaction product can be correctly analyzed by this method with no adverse effect of endogenous substances because these interfering substances have been removed prior to measurement.

Title: High pressure diaphragm pump
Inventor: WILLIAMS JAMES F
IPC: F04B43/06
Filed: 1989-06-30
Granted: 1992-07-07
Abstract: ABSTRACT     A diaphragm pump especially suited for use in a high pressure application.  The pump is devised to replenish any hydraulic fluid lost from a motor chamber, especially that fluid forced past the seals circumscribing a reciprocating plunger that is partially inserted into the motor chamber and is used as a means to alternately generate and release the high pressures that must be generated in the motor chamber to overcome the opposing high pressures existing in a pumping chamber containing a transient fluid.  The motor chamber and the pumping chamber are separated by a diaphragm that is displaced according to the pressures in the motor chamber and the pumping chamber.  Whenever the pressure generated in the motor chamber is such that the pressure in the pumping chamber is overcome, the pumping chamber shrinks in size and the transient fluid is expelled from the pumping chamber.  Whenever the pressure in the motor chamber is released, the pumping chamber increases in size and the transient fluid is drawn into the pumping chamber.

Granted: 2001-02-20
Abstract: The invention provides new methods and apparatus for the deposition of materials on substrates by the use of a D.C. glow discharge, sometimes also called a plasma discharge. A precursor gas (or gases), which is a decomposable compound of the required material, is introduced at low pressure (10-500 milliTor) into an enclosure containing two spaced parallel cathode electrodes and an intermediate parallel anode electrode, preferably midway between the two cathodes. Upon the application of a suitable positive potential to the anode a deposition plasma is generated in the space on both sides of the anode, primarily it is believed by electrons that oscillate back and forth through the anode, giving an increased free path for collisions and rendering the dissociation process more efficient. The plasma of charged and neutral radicals moves to the cathodes both by charge attraction and by diffusion, giving high quality films at increased deposition rates, higher possible discharge current densities, lower gas pressures with consequent gas economy and safety, improved film adhesion, and greater independence of these parameters from one another than has been possible with the prior art processes. To avoid encroachment of the plasma on the cathodes and substrates supplementary cathode electrodes may be interposed between the first-mentioned cathodes and the anode close to the former, so that the plasma is confined between the supplementary cathodes.
