Abstract: ABSTRACT      Stick and stud welding apparatus which utilizes a microprocessor and related RAMs, ROMs and peripheral inter-face devices to control the weldinq parameters.  The ideal desired weld current and weld cycles in the case of stud welding can be selected depending upon the mode of opera-tion and/or stud conditions.  The program for the micro-processor instructs the microprocessor to periodically compare the actual welding current to the ideal current, compute the difference and alter the phase firing time of an SCR bridge to compensate or adjust the weldinq current to the ideal current.  In the case of stud welding mode, the program further instructs the microprocessor to reference the selected number of cycles, compute the total energy delivered across the stud and workpiece gap from actual current, welding terminal voltage and time and enlarge the number of actual weld cycles to a given per-centage of that initially selected to provide a total energy input to the stud as selected.  In the stud mode, the pilot arc current and cycles may likewise be selected and controlled.  Such parameters as pilot arc current, pilot arc cycles, main welding current, main welding current cycles, total enerqy, weldinq terminal voltage and error occurrence are displayed visually by means of lights and/or written printout.

Abstract: STRUT MOUNTED MULTIPLE STATIC TUBE     ABSTRACT OF THE DISCLOSURE A strut mounted multiple static tube providing, as shown, multiple separate static pressure measuring systems and using one probe with separate sets of pressure sensing ports for each system.  The probe is designed to have a surface configuration which provides substantially identical static pressure conditions at each set of sensing ports while the axial length of the barrel portion of the sensing probe is maintained at a minimum and the pressure effects from the adjacent structures such as the strut are compensated for.  The structure includes a barrel portion of the probe having a surface annular wave pattern with sections of different diameters which causes large, uniform changes in the pressure pattern along the probe to provide areas of both positive and negative pressure levels for aerodynamic compensation.  The positions for the ports for the separate systems are selected from a pressure profile of the probe so the ports are located at desired pressure areas.

Abstract: ABSTRACT OF THE DISCLOSURE         A method of modulation and demodulation of data converts data words of four bits to converted data words of twelve bits according to a normal coding scheme in which successive marks or "1" bits are separated by at least five spaces or "0" bits.  At least two consecutive four-bit data words are furnished to a logic device that detects whether the last "1" bit of one converted data word corresponding thereto according to the normal coding scheme will be less than five bits from the first "1" bit in the next converted data word, and provides appropriate key bits; and converted data words are selectively provided according to the normal coding scheme and according to an alternate coding scheme in response to such key bits, so that in the modulated data, the "1" bits are always separated from each other by at least five "0" bits.  For demodulation, a logic device provides a discrimination bit depending upon whether the converted data words have been modulated according to the normal or the alternate coding scheme, and a selector responsive to the discriminator bit selects data words according to the normal coding scheme and according to the alternate coding scheme.          The apparatus for modulating data preferably includes an addressable ROM as a coding device.

Abstract: UNIVERSAL CAPPING MACHINE           ABSTRACT OF THE DISCLOSURE         This relates to a capper for applying closures to containers.  In a packer's plant there is frequently a necessity to modify a capper so as to apply closures to containers of different diameters and different heights with the closures also being different in diameters, thick-nesses, etc.  In the past, the cappers have been provided with change parts and are in a certain degree adjustable so that a capper can be modified to accept a range of con-tainer diameters and heights and closure sizes.  However, shut-down time has continued to be an important factor.          Further, final adjustment of the capper after modification has been a problem.  There has been provided a universal capper which is provided with height and width adjustments for both containers and closures and all of these adjust-ments may be made while the machine is operating so as to obtain minute adjustments.  The changeover time is no longer a factor with the universal capper.  This abstract forms no part of the specification of this application and is not to be construed as limiting the claims of the appli-cation.

Abstract: ABSTRACT DISC-PLAYING AROMA GENERATOR A disc-playing aroma generator whose appearance and function are analogous to those of a phono disc record player, the user when playing a selected aromatic disc enjoying an olfactory rather than an auditory experience. Each aromatic disc houses a supply of a liquid fragrance whereby when the disc is inserted in the player, an aromatic vapor is then discharged into the atmosphere. The disc is formed by a circular sheet of absorbent material impregnated with the liquid fragrance and sandwiched between a pair of annular plastic films which are peripherally joined to create a central zone exposing the impregnated sheet. In the player, heated air under positive pressure is forced through the central zone to volatilize the liquid to produce a vapor which is discharged through vents in the casing of the player. The aromatic disc is packaged in a transparent sleeve having circular spindle labels on both sides thereof which overlie the central zone to impart thereto the appearance of a conventional phone record and serving to identify the fragrance.
