Abstract: ABSTRACT          A fixed fluid control system for loading fluids into sealed tanks includes pressure sensing conduits in a mobile vehicle and fixed fluid controls.          In the vehicle are first and second pressure sensing conduits having portions within the sealed tank posi-tioned at the top and bottom of the tank.  The pres-sure sensing conduits have exterior portions to which are detachably coupled additional pressure sense lines.  The additional pressure sensing conduits are coupled to a differential pressure to current conver-ter within the fixed fluid control system.  The con-verter produces a current signal proportional to the pressure difference between the two sense lines.  When this current reaches a predetermined high level, the supply of fluid to the sealed tank is discontinued.

Abstract: Abstract of the Disclosure The invention relates to a device for the burr-free cutting of strip-shaped material, especially made of metal, which has, for each cut, two pairs of circular knives on axis-parallel knife shafts.  The strip-shaped material is cut into by the first pair of circular knives in the first parting step and is severed in the opposite direc-tion by the second pair of circular knives in the second parting step.  The characteristic feature of the invention is that the counter-knives of the two pairs of circular knives are arranged on a common knife shaft so as to rest against one another, and that they consist of an outer rigid, especially metallic, cutting ring and of an inner annular elastomeric hub part.

Abstract: ABSTRACT OF THE DISCLOSURE        A radio ranging system has at least one receiver which receives pulses over a direct path and over a longer delayed path from each of two or more fixed repeater stations.  From the reception times of pulses which have traveled over these paths at different travel times from the fixed stations, a computer calculates the hyperbolic distances separating the passive re-ceiver and the several fixed reference stations.  By interchang-ing the roles of the various fixed stations, the computer com-pares the results of timing calculations of the same distances based on the different sets of data.  From this comparison, the systematic timing errors of the system can be isolated and added or subtracted from the time measuring results, leaving differen-tial time measurements without systematic error.

Abstract: COMPREHENSIVE ENGINE MONITOR AND RECORDER            Abstract of the Disclosure A  comprehensive  turbine  engine  monitoring  and recording system includes an electronics unit which may be engine mounted,  and which contains at least a non-volatile memory and a data-processor,  for use with a remote unit suitable for either cockpit mounting or for accessing by a ground portable unit which may include an additional  data-processor  and  display  and/or  printer units.   Raw input data is supplied to the electronics unit, and this input information may include engine and outside air temperature, torque, engine speed, vibration, altitude and  airspeed data,  for examples.   Exceedance data relative to the operation of the aircraft above pre-defined limits of temperature, torque and speed are recorded,  with the details of each exceedance being permanently stored.  In addition, over-limits levels are segregated and the total time during which the engine is operated within each of the over-limits bands is mea-sured, and is recorded in a non-volatile, electronically alterable memory which  is periodically updated  during operation of the aircraft or upon power loss or termi-nation.  The number of starts, and power cycles are also counted and stored,  and the total running time of the engine is also recorded.  Data required for engine trend monitoring is also automatically recorded so that long term plots and interpretation of engine degradation may be accomplished.  Upon command from the remote unit, information is transferred from the non-volatile memory to any of a number of remote data storage,  or data processing  units,  which  may  include  printer  and/or display units, so that the time at which the turbine has been operated at specific over-temperature levels,  and other important operating data may be readily accessed.
