Title: Plasma arc transfer controller
Inventor: TRAXLER JOHN C
IPC: B23K9/095
Filed: 1990-02-08
Abstract: ABSTRACT OF THE DISCLOSURE        The invention comprises a power transfer circuit for a plasma torch for smoothly and linearly transferring the plasma arc from the nozzle of the torch to a workpiece as cutting operation commences and vice versa as cutting operation is completed. The invention includes a switching transistor for alternately providing power to the nozzle of the workpiece and a freewheeling diode coupled between the workpiece and the power source.  The transistor is responsive to the voltage differential between the workpiece and the nozzle for transferring the plasma arc therebetween.  Below a specified voltage differential, the transistor is turned off such that all power is delivered to the workpiece.  Above a specified upper voltage differential, the transistor is turned on and all power is delivered to the nozzle.  Between the specified upper and lower voltage differentials, the transistor switches at a specified frequency, the duty cycle of the transistor (i.e., the period of each cycle during which the transistor is turned on) increasing as the voltage differential increases.  In a further aspect of the invention, the level of power output is ramped from a first level to a second level as the voltage differential between the nozzle and the workpiece crosses through a third specified voltage threshold.   3085m

Abstract: A Coriolis mass flow rate meter for measuring the mass flow rate of material flowing through a conduit. The flow meter includes at least one flow tube (12 and 14) through which the material to be measured passes. The flow tube is vibrated at its natural frequency so that the concurrent flow of material through the vibrating tube produces a displacement of the tube with the magnitude of the displacement being dependent upon the magnitude of the generated Coriolis forces and the mass flow rate of the measured material.  The phase of the displacement of the flow tube is measured using optical fiber sensors (170L and 170R) comprising at least one loop of optical fiber which is flexed by the displacement of the flow tube.  This flexing of the fiber causes a corresponding change in its optical conductivity  and  a  corresponding  change  in  the intensity of the light transmitted through the fiber from a light signal source (160) to a signal detector (192L and 192R).  The modulated light signal received by the optical signal detector is converted to an electrical signal which is processed to generate the mass flow rate and other information for the flowing material.   A feedback circuit (201)  for the light signal source monitors the average intensity of the light received by the signal detector and controls the drive signal  (202)  applied to the light source to maintain the average intensity of the light signal received by the detector at a predetermined initial intensity.

Abstract: The security for a person in a domicile, premise, or dwelling, is increased in the effectiveness thereof, by utilizing a remotely accessible security controlled audio link, which provides a hands free telephone answering system, that operates without the utilization of any conventional telephone located in the domicile.  In a normal mode of this audio link, the telephone of a domicile is used in a conventional manner.  However, when a telephone in the domicile is not answered within a time period of a designated number of rings, then the remotely accessible security controlled audio link operates to answer the incoming call by, in effect, functioning in an equivalent way, to lift up a conventional receiver, without the conventional receiver ever being raised.  Thereafter, if a correct pulse tone entry code is entered by a person at a remote location, within a limited time period, telephone voice communications can begin and will continue between a person in or near the domicile and a person at a remote telephone location, thereby expanding the security available for a person in and around a domicile.  Also if an alarm signal is initiated by a person in and around a domicile, then an alarm mode is established.  Thereafter the remotely accessible security controlled audio link operates to bypass the privacy security features thereof, by eliminating the functions of both the ring counting delays and correct pulse tone entry codes, and instead functions to quickly establish telephone communications, while in this alarm mode of operations.

Abstract: CRYSTALLIZATION ENHANCEMENT OF POLYOLEFINS          ABSTRACT  Polymer compositions having  a  first and  second portion  selected  from  polypropylenes,  polyethylenes, propylene-ethylene copolymers and mixtures thereof having enhanced  crystallization  properties  and  a  method  for producing the same are disclosed.   Antioxidant is mixed with  the  first  portion,  0.01  to 1.25  wt  %,  of  the composition which is then irradiated to a dosage of 5-30 Mrads  of  ionizing  radiation  in  air  to  induce  cross linking. The irradiated first portion is then blended with the  non-irradiated  second  portion.    The  cross-linked polymer is believed to provide nucleation sites for the initiation   of   crystallization,   thereby   enhancing crystallization of the polymer as evidenced by elevated DSC freeze points.  Crystallization of the polyolefin is enhanced without any detrimental effects on hexane  or xylene extractability of the polymer and without degrading the composition to any appreciable extent.

Abstract: Effective control of impedance values in integrated circuit applications is achieved with an integrated circuit transistor whose size is digitally controlled. The digitally controlled size is achieved, for example, with a parallel interconnection of MOS transistors. In one application, the digitally controlled transistor serves as a controlled impedance connected to an output terminal of an integrated circuit. In that application, a number of transistors are enabled with control signals, and the collection of enabled transistors is responsive to the input signal that normally is applied to a conventional transistor. In another application, where the digitally controlled transistor serves as a controlled impedance at the input of a circuit, only the control signals that enable transistors and thereby determine the effective developed impedance are employed. In still another application, the digital control of the transistor's size is employed to controlthe speed or power consumption of the effective transistor. Such control is exercised to erase the manufacturing variability of the integrated circuit. Alternatively, such control is exercised as part of a feedback control of the operational characteristics of the entire circuit. In the feedback control application, the digital signals that control the transistor's size are obtainedfrom an assessment of the circuit's operation. In the manufacturing variability control application, the digital signals that control the transistor's size are obtained from a measure of the integrated circuit's paramenters relative to a reference element.
