Abstract: ABSTRACT         Devices are known for measuring .alpha.-radiation produced by airborne particles, but in these devices the detectors are upstream of a filter used to collect the particles which means that the detectors are subject to dirt buildup from airborne particles.  The present invention avoids this problem in that the detector is on the downstream side of the filter.  The device includes a chamber into which air is sucked through the filter covering one end of the chamber.  The filter is of a type through which .alpha.-particles may penetrate.  The .alpha.-particles are detected by a scintillation screen and photodetector at the other end of the chamber.

Abstract: ENVIRONMENTAL CUT-OFF FOR DEEP EXCAVATIONS               ABSTRACT OF THE DISCLOSURE        High density polyethylene sheets are installed in panel forms to form an impervious barrier to fluid flow particularly corrosive contaminates and pollutants.  A slit is excavated in the earth under a bentonite slurry to the required depth.  A relatively thick, nigh density poly-ethylene sheet is placed in the trench and connected to two high density polyethylene pipes or channel members, the width of which, in the direction transverse to the direc-tion of the wall, is the width of the trench.  The panel length typically will be 15 to 30 feet.  Once the high den-sity polyethylene panel is installed, the slurry is dis-placed on both sides by a backfill material that can be a soil-bentonite, cement-bentonite or concrete.  A secondary panel section intermediate two previously formed primary panels is made using a secondary panel of high density poly-ethylene similarly constructed but using smaller diameter pipe or channel members than the primary panel pipes.  This panel is then lifted and the two smaller pipes or channels lowered into the primary panel pipes or channels with the high density polyethylene panel extending between through two slots or openings in facing primary panel pipe or channel elements.  A non-shrinking grout is then pumped into the pipe connection to form a tight joint.

Abstract: Abstract of the Disclosure A  transmission path  is monitored for its suit-ability  for  transmission of digital  data by trans-mitting over the transmission path a video test signal which includes a horizontal sync pulse and at least one half-cycle of a generally sinusoidal pulse occur-ring at a predetermined time after the sync pulse, the generally sinusoidal pulses being inverted in alter-nate  lines  or  alternate  fields  of  the  video  test signal.  The signal received at the other end of the transmission path is displayed on an oscilloscope-type CRT  device having  its horizontal sweep triggered by the horizontal sync pulse,  so as to superimpose the alternate generally sinusoidal pulses. The configura-tion of the generally eye-shaped area resulting from such superimposition depends on the suitability of the transmission path for transmission of digital data.

Abstract: Abstract The present invention provides a communications system that  improves  upon  the  availability  of  communications paths  between  devices  and  simplifies  the  connectivity requirements to communicate data and control information to and from a remote station.  System nodes are provided which are disposed along a time multiplex network signal stream.   The nodes serve to interface remote stations to the network signal stream and may also switch information to different stations  connected to the same node.   The nodes are operative to allocate a variable bandwidth of the network signal stream for data communications between devices connected to different nodes.   The nodes include switching devices  that may be configured to accommodate stations that operate at different speeds.  Allocation of bandwidth  may  be  dynamically  varied  such  that  system resources  are  not  unnecessarily  diverted.   Control  of bandwidth  allocation  and  internal  switching within  the node is accomplished via control information communicated to and from the node.   Such control  information may be contained within the network signal stream and decoded by the node  or  communicated  to  the node  via  a  dedicated control communications line.   Control information may be encoded into the signal stream communicated between the system node and the remote station.   Thus, communication of data and control signals between the stations and the system node does not require complex wiring.  Accordingly, individual stations may be more conveniently located.
