Title: Cylindrical foundation support drivable into ground with removable helix
Inventor: HOLDEMAN MAYNARD L
IPC: E02D7/22
Filed: 1991-07-19
Abstract: ABSTRACT A  combined  foundation  earth  anchor  and installation  unit  includes  a  cylindrical  foundation support which is open at opposite ends and adapted to at least  partially  be  embedded  in  the  ground,  an installation drive component removably positioned within the support and provided with an  element extending longitudinally  through  the  support  and  projecting outwardly from one end thereof,  and a connector for releasably coupling the installation drive component to the support, so that upon rotational movement of the drive component, the support is rotated therewith.  The installation drive component includes a drive helix on the end of the element which projects outwardly from one end of  the  support,  so that upon application of a rotational force to the assembled foundation support and drive component, while a downward force is applied to such assembly, the drive helix causes the support and drive assembly to be pulled  into the ground.   The installation  drive  component  element  which  extends outwardly from one end of the support has a guide structure  which  is  engagable  with  the  support  for maintaining axial alignment between the support and the drive  component  during  installation.     The  guide structure cooperates with the drive helix to cause the foundation and drive component assembly to be drawn into the ground during the application of rotational force to the support and drive component assembly.   When the support has been driven into the ground to the desired level, the drive component may be disconnected from the support and removed by reverse rotation thereof, leaving the foundation support in the ground.  A method of at least  partially  embedding an  open-ended  cylindrical earth anchor in the ground is also disclosed.

Title: Pager with automatic detection of insertion into holster
Inventor: PANTHER GYLES
IPC: G08B3/10
Filed: 1991-11-12
Abstract: Abstract A holster for a radio pager contains a vibrator which can be driven by the matching radio when the pager is inserted into the holster.  The pager and holster have matching electrical contacts which are made when the pager is inserted into the holster.  The pager contains means to sense the connection of the vibrator motor and to convey this data to an internal microcontroller.  The microcontroller has the capability to alter the mode of alert from vibrate to an alternate alert mode such  as audible alert, according to the preselected choice of the user, under control of the vibrator sense signal.  The vibrator sense circuit output is also used by the microcontroller to invert the display, to provide for on-belt reading of a front faced alpha-numeric pager.  The use of a mechanical detection mechanism is also described for pager holster configurations in which the vibrator is contained in the pager.

Abstract: A halftone screen pattern generation system for computing halftone screened images with rotated screens including multiple angle and ruling combinations, including irrational tangent angles, is disclosed.  A screen pattern is generated by storing a plurality of  strips  from  an  ideal  angled  screen  pattern,  and  then concatenating  a  sequence  comprising a  selected  order  of  the plurality of strips in a sequence.  The error between the actual generated screen and ideal desired screen is computed.   Each subsequent strip is selected from the plurality of strips so as to reduce the accumulated error.  In one embodiment, a screen pattern is generated by storing one strip of an ideal angled screen pattern, and then concatenating a selected sequence comprising the strip and substrips of the strip.   In accordance with another aspect of the present invention, the measure of error between the actual generated screen and the ideal angled screen is the length of a vector in a transformed UV space between the actual screen sample point and the idealized screen sample point.  The error is determined by vector addition of the accumulated error, from strip to strip, which is added to the present error contribution from the present strip.

Abstract: Fluxing compositions containing compounds that generate acids upon photoinitiation from a light source such as Hg/Xe ultraviolet (UV) light sources are described. The acids clean oxides from the printed circuit boards (PCBs) under assembly and then volatilize with little or no need for a cleaning step, or cleaning only with water. The compounds that release an oxide removing agent, sometimes called a "photoacid" include metal and organic onium salts and furyl compounds bearing a carbonyl group. Such fluxing compositions can be used mixed with typical solder formulations. such as lead/tin solders, or applied topically thereto; both techniques permit the assembly of PCBs more easily and with high quality bonds.
