    摘要： A system and method for isolating data messages received from subscribers in a CATV system are disclosed. The system includes a spectrum parallel router which receives data messages in the return spectrum of a service line at a service site. A switch at the service site directs data messages to service lines coupled to the site which have destination addresses corresponding to one of the service lines. Data messages not having a destination address corresponding to one of the service lines are provided to a transmitter for transmission to the next higher level of the CATV network over a return cable. Each service site has its own return cable which may be coupled to a distribution hub or a headend. The return cables isolate the data messages of each service site from the data messages sent by the other service sites. At the distribution hub and headend, a switch is provided for each return cable and the switches are coupled to one another. At a distribution hub, data messages having a destination address corresponding to one of the other switches at the hub are routed to the corresponding switch. Messages so received by a switch at a distribution hub are coupled to a transmitter for transmission to the next lower network level coupled to the switch. Destination addresses in data messages not recognized by a switch at a distribution hub are coupled to a return cable for transmission to the next higher level in the network. At the highest level of the network, a headend is provided which includes a switch for each return cable coupled to the headend and each switch at the headend is coupled to the other switches for the routing of data messages as performed at the distribution hub. The system preferably includes frequency stackers and destackers so data messages from each service line may be placed on separate data channels to further enhance message isolation and reduce message traffic in the spectrum of a transmission or return cable.

    摘要： In an auger-type product chiller having an auger including a series of successive flights that form a generally helical structure that, when rotated, moves product through cold water for chilling the product, control elements extending from faces of the flights at a non-zero angle. The control structures prevent "clumping" and packing of poultry product, break up any "clumps" and packs of the product that may develop, and improve product uniformity. In this manner, the advantages of proper agitation, as well as rapid, predictable and even product cooling and moisture introduction, are achieved. Implementations of the control elements include sets of rods extending from the flights at 30.degree. angles from radial lines of affixation to the flights, flat plates extending from the flights at 30.degree. angles from radial lines of affixation to the flights, and sets of rods extending between successive flights near peripheries of the flights.

    摘要： An ultrasonic, transcutaneous blood flow detector. A protective mounting cup is positionable against the skin of a patient for the transfer of ultrasonic energy into and out of the patient's body. The detector utilizes only a single piezoelectric transducer with a first face in juxtaposition with an interior face of the cup. A film of viscous semifluid material is positioned between the transducer first face and the cup's interior face to couple ultrasonic energy between the transducer and the cup. A resilient spring or foam member resiliently biases the transducer first face into engagement with the cup's interior face with the semifluid material therebetween, thus permitting substantially uninhibited deformation of the transducer in response to a drive signal. A transmitter supplies a continuous wave drive signal to the transducer, and a detector circuit operating concurrently therewith detects the Doppler frequency shifted electrical signal generated by the transducer as a result of the Doppler frequency shifted acoustic energy reflected back to the transducer. The transmitter provides the drive signal to the transducer with an output voltage automatically variable in response to loading of the transducer with reflective energy. An amplifier and audio binaurals provide a variable pitch audible tone to the user.

    摘要： A dynamoelectric machine having a quiet cooling system. The system comprises at least twenty-five short chord axially mounted radial blades disposed on a conical hub which is disposed on the rotor of the dynamoelectric machine. The arrangement and number of blades are such that the coolant flow is increased while the pure tone noises are reduced thus increasing cooling and reducing subjective annoyance. A conical shroud encloses the conical hub defining therebetween a conical annulus whose total annular cross-sectional area does not expand to the point where turbulence and flow separation would occur. A bell-mouthed protective grilled inlet is disposed on the conical shroud for conducting a coolant, under the action of the rotating blades, through the bell-mouthed inlet and into the conical annulus. The bell-mouthed inlet and conical annulus together providing a streamlined path for quietly diffusing the coolant into the proximity of surfaces susceptible to heating.
