Abstract: ABSTRACT       A real time geophysical survey system and method.  The system  comprises  a  base  station,  one  or  more  data acquisition  vehicles,  and  one  or  more  fixed  reference stations.  The base station is provided with a positioning system,  suitable  survey  instrumentation,  a  computer,  and radio   communication   equipment.   The   data   acquisition vehicles are each provided with a positioning transponder, a positioning display,  suitable  survey  instrumentation,  and radio   communication   equipment.   During  a  survey,   by periodically polling each vehicle's positioning transponder, the base station positioning system tracks the position of each vehicle with respect to both the base station and the fixed  reference  stations.  Data  regarding  each vehicle's position are then provided to the base station computer, and the  base  station  transmits  signals  to  the  positioning display aboard each vehicle so as to guide the vehicle along a preselected  survey  pattern.  As  the  survey progresses, data   representing   geophysical   measurements   taken   by instrumentation carried by  each vehicle  are  periodically transmitted to the base station computer.  Such data  are then  correlated  in  real  time  with  the  position of  the vehicle and with data collected at the base site, and then output for evaluation by the base station computer.

Abstract: ABSTRACT OF THE DISCLOSURE A pipe belling apparatus is disclosed which includes an elongated frame to support all of the operating components.  A pressure chamber is reciprocal upon frame supported rails between an initial position and a belling position for continuous plastic pipe belling operations.  Within the pressure chamber is supported a shaped mandrel to impress a desired hub or bell shape in one previously heated end of a length of pipe.  Transverse pipe clamps are carried upon the frame forwardly of the pressure chamber to secure one end of the length of pipe in concentric alignment with the mandrel. When the pressure chamber and the mandrel are urged along the rails to the belling position, the mandrel will be inserted into the heated end of the pipe and a resilient, planar gasket will seal the forward end of the pressure chamber against the pipe clamps and against the pipe itself.          When the forward seal has been made up, fluid pressurizing forces are introduced into the pressure chamber to uniformly press the pipe end peripherally about the mandrel to precisely form the desired bell shape.          After a sufficient period of time has elapsed to properly form the bell shape, the seal is broken, the pressure chamber and mandrel are reciprocated to their initial positions, the pipe clamps are opened and the pipe with the bell shape is withdrawn from the apparatus.

Abstract: Labeling Apparatus Abstract An apparatus and method for applying tubular labels to a product container at a labeling station including a reciprocally movable labeling assembly.  The assembly is adjustably secured to carriage that it mounted for reciprocating movement at the labeling station.  A drive system including a drive cam defining an asymetrical profile is operativley coupled to the carriage by a lever arrangement including a cam follower driven by the drive cam.  The profile of the drive cam is config-ured to have a steep rise and a gradual drop so that the average speed at which the labeling assembly is driven through a label applying strobe is substantially less than the speed at which the assembly is driven through a return stroke thus reducing the stress applied to the label as it is installed.  A fluid pressure oper-ated actuator pressurized to a first predetermined pres-sure exerts a biasing force on the lever to urge the cam follower into contact with the drive cam.  A sensor monitors the contact between the follower and cam and de-energizes the drive system and arrests rotation of the drive cam in the event loss of contact between the follower and the cam is sensed.  The fluid pressure operated actuator can also be pressurized to a second predetermined pressure in order to drive the carriage to a retracted position.  An indexing cam is co-driven with the carriage drive cam and operates a bottle advan-cing mechanism in synchronization with the labeling assembly.

Abstract: ABSTRACT OF THE DISCLOSURE      Disclosed is a structure having two highly and similarly doped,  e.g.,  P+ type,  regions  embedded in close juxtaposition in a trench-isolated N type silicon mesa which contains the novel feature of N+ channel stops embedded in the N type mesa between the P type regions.  The  channel  stops  are  self-aligned  to  the walls of trench to arrest charge leakage between the P type regions due to parasitic transistor action along the trench wall. The P type regions may constitute two resistors, the emitter and collector of a lateral PNP transistor,  etc.  The  dopant  concentration in  the channel stops is about one to two orders of magnitude higher than that in the N type silicon.     Disclosed  too  is  a  process  of  forming  channel stops which starts with a, for example, N type silicon substrate having on the surface thereof an insulator trench mask defining the region of silicon where an isolation trench is desired.  A blockout mask having an opening  in  correspondence  with  the  portion  of  the would-be silicon mesa where a channel stop is desired is  formed.   N  type  dopant  is  introduced  into  the exposed silicon followed by an anneal step to laterally diffuse the dopant into the silicon body. The exposed silicon is etched forming a deep trench which delin-eates silicon mesa having at a section of the peripher-al portion thereof a shallow and highly N doped region. Upon forming a pair of highly P doped regions on either side of the shallow highly N doped region, the latter functions as a channel stop to arrest charge leakage between the P doped regions due to parasitic FET action at the trench walls.

Abstract: ABSTRACT    An apparatus for detecting the concentration of certain analytes, including hydrocarbons, in a liquid medium, is disclosed.          The apparatus uses a planar or "open" capacitor containing an active layer.  In response to selected analyte in the liquid medium, the active layer causes capacitance to decrease with increasing analyte concentration.  The capacitance decreases because higher dielectric water molecules are displaced from a region of the capacitor's electric field.  For certain hydrocarbon analytes having high Henry's Law constants, the active layer causes bubbles to nucleate in the liquid medium on the surface of the active layer.  Bubble formation displaces water molecules and decreases capacitance.
