Abstract: Abstract of the Disclosure The initialization and preparation procedure described involves particularly ultrasonic test equipment for ultrasonic inspection of welding seams of pipes while passing through a production line.  A dummy is used off line to determine suitable distances and orientation of test heads and to acquire relevant transit time and amplitude data.  A standard is then used to obtain additional reference data to be related to the dummy test data.  After the test heads are installed in the production line test stand, tests are repeated with the standard to obtain now the needed test reference data in conjunction with the previously related data.  This way, looking windows for flaw echos as well as sensitivity data for the subsequent tests are accurately and reproducibly predetermined.

Abstract: AN OXYGEN MONITOR AND WARNING DEVICE FOR AN AIRCRAFT BREATHING SYSTEM                    ABSTRACT OF THE DISCLOSURE In an aircraft breathing system a sensor assembly for monitoring the concentration of oxygen in a source of breathable fluid supplied to a recipient.  The sensor assembly has a housing with a chamber therein connected by a conduit to the source of breathable fluid.  A restricted orifice member in the conduit allows a sample of the breathable fluid to continually flow into the chamber while an exit port in the housing allows the sample of breathable fluid to flow to the surrounding environment.  A sensor responsive to the partial pressure of oxygen is connected to the chamber.  The sensor in response to the partial pressure of the oxygen produces an operational signal.  The operational signal activates an indicator to provide the recipient with a reading of the concentration of oxygen in the breathable fluid.  An aneroid fixed to the housing has a face that engages a seat surrounding the exit port. Whenever the aircraft is above a predetermined altitude to establish a constant absolute pressure for the sample in the chamber.  This constant absolute pressure stabilizes the operation of the sensor and thereby maintains a uniform indication of the percentage of oxygen in the breathable fluid above the predetermined altitude.

Abstract: ABSTRACT OF THE DISCLOSURE A data processing system having a host processor, a host memory, a host memory management unit and an input/output bus and further including a separate input/output (I/O) processor with its own local memory for handling the transfer of data between I/O devices on its own I/O processor I/O bus and the host main memory.  The I/O processor has the capability of directly ac-cessing main memory via the host standard data channel.  The I/O processor has the capability of interrupting the host processor operation in a special way (by a "micro-interrupt" process) such that the host processor thereby re-allocates the contents of a selected memory allocation unit (MAP) of the host memory management unit faster than using standard interrupt routines.  Such re-allocation then permits the I/O processor to transfer data directly to and from the host main memory via the re-allocated memory management unit without the need for further processing by the host processor, the I/O processor pro-viding a suitable identification of the selected MAP which is to be re-allo-cated.  The system further prevents access to the host memory by any other I/O processor while a first I/O processor is performing a read-modify-write operation with respect to the host memory.
