Abstract: ABSTRACT      A self-referencing self-oscillating power converter is disclosed.  The power converter operates in the flyback switch mode to convert a high voltage DC power source to low voltage regulated power supply voltages applied to a load.  Energy is stored in a primary winding of a power transformer during energy store cycles by causing a current to flow in the primary winding.  This current is interrupted and the stored energy is delivered across the transformer to the load during an energy transfer cycle. The converter includes means for sensing the current in the primary winding at low voltage potentials, and for controlling the duration of each energy store cycle in response to the level of current in the primary winding to deliver the power required to drive the load at the regulated voltages.

Abstract: ABSTRACT OF THE INVENTION         A multi-lead  component  manipulator  for  the assembly of circuit boards has optical and tactile feedback systems and includes at least two and preferably three symmetric assemblies radially disposed about a component gripper assembly.  Each symmetric assembly has a movable lead guide means for engaging a component lead and align-ing the same for circuit board insertion.  The guide means are  adapted  for  independent  arcuate  and radial motion reflective of the optical feedback system and the gripper assembly is capable of axial movement for the acquisition and insertion of components.  The tactile feedback system controls  component  insertion.   The  manipulator  in  an alternative  embodiment  has  fixed  guide  means  disposed above  the movable  guide means.  The  fixed guide means orient the component leads for acquisition by the movable guide means.

Abstract: ABSTRACT OF THE DISCLOSURE     A novel method for preparing a ground-meat sample for compositional analysis and an apparatus for performing the method are disclosed.  The meat is spread into a layer having a predetermined thickness.  A first portion of the layer is isolated from the remainder.  The iso-lated first portion is then urged into an elongated, hol-low member having an axis, an open end, and a resistive end movable along the axis relative to the open end. The isolated first portion and the resistive end are urged together so as to produce a substantially air void-free isolate out of the first portion.  A subsequent portion of the layer is isolated from the remainder and urged into the hollow member and against the isolate in the hollow member thereby causing the resistive end and the isolate engaging the resistive end to move axially through the hollow member.  The hollow member is repeatedly filled with subsequent layer portions, in the manner described immediately above, until the hollow member is predeterminedly filled with the ground meat thereby pro-ducing an analyzable meat sample.

Plural control grid electrodes are arranged between the display segments and the cathodes in corresponding relation to the display segments.  A common accelerating electrode is disposed between the display segments and the control grid electrodes.  The voltage applied to each control grid electrode is controllable for electron emission from the cathodes so as to render each display segment corresponding to each control grid electrode selectively luminous for display.  Furthermore, a separator surrounds each display segment end it is supplied with the above anode voltage so that a diffusion lens is formed which allows the electron beam from the cathode to be spread laterally and radiated to the entire surface of the display segment to be rendered luminous.

Abstract: ABSTRACT        The base part of an emergency running ring manufactured from an elastomer material changes into two upwardly inclined, outwardly directed support pieces having a high load capacity.   The support pieces enclose a drop-base, groove-shaped annular channel and have a stepped outer flank.  At least one annular groove filled directly or indirectly with a lubricant and closed by sealing lips communicating with the annular channel through at least one sealing lip forming the load end of the associated lever-like support piece.  In intact pneumatic tires the sealing lips are held in the closed position on account of the nip pressure prevailing in the base part and, if necessary, through additionally inserted expanding fillers, but with the onset of the emergency running are opened by the wheel load acting on the support pieces, whereby the lubricant is released and reaches the contiguous surfaces between the pneumatic tire and the emergency running ring for lubrication.     This emergency running ring is characterized above all by the fact that it has a low weight and offers the defective pneumatic tire a wide support surface.  In addition, its outwardly directed support pieces advantageously support the flanks of the pneumatic tire when they are subjected to the effect of transverse forces when cornering.  This emergency running ring is particularly suited for assembly in tubeless pneumatic tires for heavy road vehicles having two-part or multipart flat-base or steep shoulder rims of a large width.

Abstract: TITLE               A TECHNIQUE FOR SCALING CHARACTERS IN                    A STROKE-VECTOR DISPLAY SYSTEM            ABSTRACT OF THE DISCLOSURE        A technique is disclosed for use in an electronic raster-scan display system, for generating characters of variable size using a stroke-vector technique.  An incoming data signal defines the type of character to be displayed, the horizontal X and vertical Y character field dimensions, the character drawing point, and any character rota-tion or reflection.  Using that part of the data signal that defines the character type as a memory address, a character microprogram is retrieved containing a stroke-vector character mask and a stroke resolution factor representing the number x of horizontal stroke-vectors in a straight line and the number y of vertical stroke-vectors in a straight line that are used by said character mask to represent said character within a normali-zed character field.  To scale the size of the stroke-vectors the hori-zontal length stroke-vector attribute DX-LENGTH is forming by taking the quotient X/x, and the vertical length stroke-vector attribute DY-LENGTH is forming by taking the quotient Y/y.  Then the DX-LENGTH attribute and the DY-LENGTH attribute are converted from the display screen coordinate system to a virtual screen coordinate system having a greater resolution than the physical screen coordinate system.  One or both length attri-butes can be applied to each stroke-vector.  At this point the character image having the proper size exists in the virtual screen coordinate system.  To convert it back to the actual display screen coordinate system the size attributes DX-LENGTH and DY-LENGTH are divided down by the proper factor.  Lastly a logical pel may be generated and added to the individual stroke-vectors before the connected stroke-vectors are projected onto the display screen at the character drawing point.

Abstract: ABSTRACT OF THE DISCLOSURE    A quick release valve for releasing the locomotive auto-matic brake independently of the train brakes when an AB/D type freight brake control valve is used on the locomotive.  A release valve normally establishes a fluid control passage between the control valve and a relay valve that controls the locomotive brake pressure.  When a quick release is made, the release valve is actuated to interrupt this fluid control passage and exhaust the relay valve portion of the passage to release the brakes.  At the same time, a dissipation valve is effective to exhaust auxiliary reservoir pressure.    If the quick release is made of a service application, the exhaust of auxiliary reservoir pressure will cause the control valve to exhaust the control valve portion of the control line and thereby prevent an automatic reapplication of the automatic brake following termination of the quick release function.  The exhaust of control line pressure also causes the dissipation valve to reset to terminate further exhaust of auxiliary reser-voir pressure, which is thus available in the event a further application of the automatic brake is desired.    If the quick release is made of an emergency application, the exhaust of auxiliary reservoir pressure will have no influ-ence on the control valve, since the brake pipe pressure will be completely exhausted, thus assuring a reapplication of the emer-gency brake following termination of the quick release operation.
