Abstract: ABSTRACT           A MOS power-on reset circuit includes Schmitt trigger circuit and an inverter.  The Schmitt trigger circuit comprises first, second, and third depletion transistors serially connected between reference poten-tial and supply voltage.  The first and second depletion transistors are connected at a first junction point, and the second and third depletion transistors are connected at a second junction point.  The gates of the first and second depletion transistors are commonly connected for receiving an input substrate bias voltage.  A enhance-ment transistor is connected between the first junction point and supply voltage.  the gates of the enhancement transistor and the third depletion transistor are com-monly connected to the second junction point, which is the output of the Schmitt trigger circuit and which is coupled to the inveter from which the output voltage is taken.  The transfer characteristic of the circuit exhibits hysteresis, with two triger levels of input substrate bias voltage that differ sufficiently in magnitude that a triggering at one level, accompanied by a fluctuation in input voltage will not cause a spurious triggering at the other level.  Undesired oscillation of the circuit is thereby avoided.

Abstract: Abstract In a vapour burner for liquid fuel there is an electrically heatable gasifyng chamber (1), a passage system (K) concentric therewith for supplying air of combustion, and a burner tube (26) which surrounds a combustion chamber (25) and is bounded at the rear by an annular closure wall (22).  The gasifying chamber (1) is formed substantially by a central gasifying tube (2).  Guide means (19) serve to produce an external annular eddy (31) of combustion gases that extends along the inside (33) of the burner tube (26) rearwardly at least over a section disposed axially in front of the mouth (23) of the passage system (K).  An ionisation measuring electrode (35) placed in the backward flow permits the flame to be accurately detected independently of the flame front which changes with a change in the burner output.  When the burner tube (26) glows, there is automatic re-ignition if the flame blows off.     Fig. 1.

Abstract: HIGH DENSITY CELLULAR MOBILE RADIO COMMUNICATIONS            Abstract In a cellular mobile telecommunication system, a method and apparatus for controlling the process of locating a mobile unit from the cell sites.  When a mobile unit goes beyond the radio range of its associated controlled cell site, that cell site sends a message to nearby cell sites to measure and report the strength of the received signal from that mobile on each of their directional antennas and to report radio channel availability.  These reports are returned to the controlling cell site which compares the received signal strength measurements against stored thresholds.  The controlling cell site generates and transmits to the mobile telecommunications switching office (MTSO) a hand-off request message including a list of candidate hand-off cell sites and directional antennas.  The MTSO then selects an available channel associated with one of the candidate cell sites and antennas and generates a sequence of messages to hand-off communications control from the controlling cell site to a candidate cell site.

Abstract: ABSTRACT    Metal  surfaces are refined,  by the process of the invention, to high levels of smoothness in relatively short periods of time.  A liquid substance is utilized to produce a conversion coating on the surface of the parts being treated, which are agitated, while being continuously wetted by the substance, in a mass finishing unit.  Abrasive action causes the relatively soft coating to be removed from the high points of the surface, while leaving substantially intact the coating on  the  lower  surface  areas,  with  the  coating  being continuously repaired over metal exposed during operation.          Fillage of the finishing unit container ensures efficient agitation and continuous oxygenation of the liquid substance, thereby maintaining a desirable rate of reaction and a high rate of surface leveling.

Abstract: METHOD OF MANUFACTURING PRINTED WIRING BOARDS            BY                       JAMES ALLAN COPPIN     ABSTRACT OF DISCLOSURE          An improved method of manufacturing a printed wiring board having the characteristics of one with a solder mask over bare copper for circuit traces and ground planes.  The method includes the step of electroplating a very thin coating of tin-lead over the circuit traces, ground planes, holes and circuit pads prior to selectively coating only the pads and holes with a relatively thick coating of tin-lead solder plate.  After removing the plating resist which defines the areas for selective solder coating, the board is chemically etched and then mechanically scrubbed to roughen the surface of and reduce the thickness of the thin solder plate.  A solder mask may be applied over circuit traces and ground planes prior to reflowing the thick coating of solder plate. Assembled printed wiring boards may then be wave soldered without wrinkling of the solder mask.

Abstract: TITLE Rotary forming machine having tie bar connection.     ABSTRACT A rotary forming machine assembly including a lower base (12) and a pair of spindle housings (14) including front (16) and rear  (18) walls.   The housings  (14) are movably mounted on the base (12) for movement toward and away from one another.   A tool spindle (20) is rotatably mounted between the front (16) and rear (18) walls of each of the housings (14) for rotation about spaced axes (B) to form a workpiece therebetween.   The invention includes a deflection control  bar   (26)   extending  between  and interconnecting  the  front  walls  (16)  of  the  spindle housings (14).  The control bar (26) limits the distance apart the (B) axes of the tool spindles (20) may move at the front walls  (16)  in response  to the forming of  a workpiece (22) between the tool spindles.  The control bar is  adjustably  supported  on  the  front  walls  16  for selective movement  in  a direction parallel to  a plane intersecting the  axes  (B).  A dual thickness  adjuster member  (118)  includes  a  rectangular  thickness (148) slidably disposed within a rectangular groove (114) formed in the front walls (10) and a trapezoidal thickness (154) slidably  disposed within a  recess  (112)  formed  in  the control  bar.  The  groove  (114)  and  recess  (112)  run perpendicular to the plane intersecting the two axes (B).          An adjustment screw  (138)  passes through a plate  (130) overlying the top edge (116) of the front wall (16) and within  the  rectangular groove  to  threadedly  engage  an aperture  (142)  in the top (144)  of the adjuster member (118).   Adjustment of the screw (138) raises and lowers the  adjuster  member   (118),   wedging   it   against  a complementary interior wall (146) of the recess (112) in the control bar (26) placing the control bar in tension to prevent the axes (B) from moving apart in response to a forming or gear-splining operation being performed on the machine.

Abstract: ABSTRACT The invention relates to the design of gearheads for manipulators which, according to the state of the art, have three axes intersecting at one point.  Through this, however, the danger arises that the gearhead can no longer be controlled in its  extended position.  To avoid this disadvantage, the invention provides for all the axes of the gearhead to be positioned dia-gonally to one another.  Thus the swivelling axis for the rear head piece is never coaxial to the axis of the concentric drive shafts, and that ambiguities in the computer control of the gearhead are thus ruled out.   772-555 str
