Abstract: SWITCHING NETWORK PARTICULARLY FOR                 HIGH VOLTAGE SUPPLY SYSTEMS     Abstract of the Disclosure A switching network has at least four nodes which can be connected in each case via three interruptable cur-rent branches to other ones of the nodes.  These nodes can be connected in at least two partial rings.  In order to retain the redundancy of such a system in the case of an expansion to more than four nodes with negligible equipment expenditure and, at the same time, little space requirement, the partial rings are constructed in such a manner that they do not have a common node in a preferred embodiment.  In this arrangement, each node of a first one of the two par-tial rings can be connected to a node of a second one of the two partial rings and, conversely, each node of this partial ring can be connected to a node of the first partial ring.          The switching network can be advantageously used, in partic-ular, in high-voltage supply systems.

Abstract: MOUNTING OF ELECTRONIC COMPONENTS ON PRINTED CIRCUIT BOARDS       Abstract of the Disclosure Mounting of leaded components on one side of a PCB and surface mounting components on the other side of the PCB creates problems. The pressure of the lead ends projecting through the PCB prevents the use of a mask for applying solder paste for the mounting of the surface mounting components.  Attaching surface mounting components initially by adhesive prior to wave soldering also causes problems.  In the present invention leaded components are inserted and the lead ends crimped.  The board is then turned over, solder paste applied by individual applicator nozzles to the lead ends and to solder pads on the circuit pattern.  The surface mounting components are then positioned with contact areas aligned with the solder pads and the whole reflow soldered.  The process can be repeated for surface mounting components on the same side as the original leaded components, with or without the insertion of further leaded components on the same side as the original surface mounting components.

Abstract: STEPPING MOTOR CONTROL PROCEDURE FOR   VARIABLE RATE, QUASI-CONTINUOUS    INTRAVENOUS ADMINISTRATION     Abstract A control procedure for governing the incremental step operation of a pump stepping motor (74) employed in conjunction with a parenteral fluid metering device (2) is disclosed.  The control procedure enables fluid to be pumped from the metering device (2) in non-pulsatile, essentially continuous fashion by suitably adjusting the stepping motor speed to compensate for the interruption of fluid flow which occurs during the refill phase (Pr) of each pumping cycle (C).  Adjustment of the stepping motor speed also compensates for non-linearities otherwise introduced into the fluid flow as a result of the camming mechanism (76,78) utilized to convert rotary stepping motor movement into rectilinear pumping movement.  Operating power for the stepping motor is conserved by drawing rela-tively large amounts of current through the stepping motor (74) only at the outset of each incremental step while drawing relatively smaller amounts of current through the stepping motor (74) during the remaining interval between incremental steps.

Abstract: Eddy Current Hot Pipe Flaw Detection Abstract An eddy current system and method is discloed for detecting flaws in hot pipe product.  The system in-cludes a detector test head (22) having a heat shield (24) defining a generally cylindrical inner wall through which the pipe passes longitudinally.  The test head includes structure (50, 62, 64) for spirally directing water onto the inside surface without contacting the hot pipe as it passes through the heat shield.  Debris is thereby removed from the space between the shield and the pipe, and the test head is effectively cooled and shielded from the heat of the pipe.  Where the pipe is heated above its Curie temperature, such that the pipe is rendered non-magnetic, no normally required saturation coil is needed to magnetically saturate the pipe for eddy current testing, because the coolant flow-ing over the inner wall cools the test head but does not lower pipe temperature below the Curie point.

Abstract: ABSTRACT OF THE DISCLOSURE         A method for recognizing particular phonemes uses the silence-phoneme and phoneme-phoneme transitions in the voice signal.  The method includes the steps of providing an electrical signal that represents the voice signal and producing, from the electrical signal, a first acoustic parameter signal containing phonemic information of the voice signal.  A transition signal is generated from the phonemic information in the first acoustic parameter signal to indicate the location of a transition in the voice signal.  Meanwhile, the first acoustic parameter signal is stored, and a second acoustic parameter signal is produced from the stored first acoustic parameter signal using the transition signal.  The second acoustic parameter signal contains phonemic information of the voice signal at the transition, and can be compared with known phonemic information to recognize the phonemic information in the voice signal.  An apparatus for performing the method is also disclosed.  The method permits accurate voice recognition without requiring excessive memory capacity because it uses the phonemic information at the transitions of the voice signal rather than at the phonemes themselves.

Abstract: ABSTRACT OF THE DISCLOSURE     An echo-compensating surface acoustic wave interdigital transducer in which the entire length of the end finger of the transducer at each end is connected directly or indirectly to at least one of the bus bars, the end finger extends only partially across the aperture of the transducer, and the space which is colinear with the end finger across the remaining portion of the aperture is not occupied by any surface-acoustic-wave-reflective structure.  The end finger is substantially a quarter of an acoustic wavelength out of phase with the nearest interior finger with respect to an incident wave at the operating frequency of the transducer, so that the acoustic reflections of the end finger and the nearest interior finger are in phase-opposition to each other.  In addition, the end finger spans one half of the transducer aperture, and is arranged to permit unobstructed acoustic reflection from the nearest interior finger over the other half of the aperture at one of the ends of the transducer, so that the resulting phase-opposed reflections are equal in amplitude in order to achieve mutual cancellation.
