Abstract: INFUSION CONTROLLING APPARATUS AND METHOD    Abstract Portable electronic medical apparatus for controlling the flow rate of a fluid for medically treating a patient may receive flow rate information representing sequences of up to 20 flow rates and their durations from an individual and from an electronic data processor, and operate continuously without the presence of an operator for in the range of 40 hours.  Upon the incorporation of an infusion pump into the apparatus, the desired regimen of treatment may be accomplished; and through a keyboard input for the apparatus, an operator may in certain respects modify a regimen which is being carried out.  The apparatus may be used in a method of treatment including:  coupling the apparatus to the processor; providing the apparatus with the flow rate information; decoupling the apparatus and processor; transporting the apparatus to the patient; coupling the apparatus to a supply of the fluid and regulating the flow rate of the fluid according to the information.  It may be similarly used in a method including the providing of an electrical signal representative of a sequence of, e.g., at least 8 discrete fluid flow rates and their durations. The signal may then, if desired, be independent of changes in the condition of the patient during such providing.  Safety features in the apparatus include:  a frequency detector for monitoring the frequency of a clocking signal for the apparatus; the selec-tive testing of output signals of the apparatus, the portable power supply for the apparatus and the frequency detector against stored predetermined standards; and the provision of warning signals to an operator to indicate divergences from such standards. Additionally, fail safe signals for the apparatus are coupled to relay circuitry to interrupt the output of the apparatus if a central processing unit for the apparatus enters undesired modes of operation.

Abstract: ABSTRACT OF THE DISCLOSURE    A wavelength division multiplexed fiber-optic communication system employs a pair of terminal stations, at opposite ends of the fiber-optic link, with the base configuration of each terminal station being the same. In each station a selective coupling arrangement is provided between the source or transmitter devices as well as the receiver devices and the single optical fiber over which the transmissions are to take place so as to effectively make the terminals interchangeable.  For achieving this purpose, each terminal station is comprised of a transmitter or source arrangement that is capable of generating a plurality of wavelengths.  Similarly, each terminal station includes a receiver or detector which is capable of detecting the plurality of wavelengths that are selectively available for transmission or generation by the transmitter or source.  The transmitter or source may comprise a single multiwavelength source such as a dual semiconductor laser generator the control and bias connections for which provide the selectivity for the wavelength of interest.  Similarly, a multiple wavelength sensitive receiver, constituting a single unit, is associated with the multiple wavelength source.  The multiple wavelength transmitter device may also be comprised of a plurality of individual transmitter or source devices the activation of which is selected by controllably switching or engaging the desired source.

Abstract: TEMPERATURE-COMPENSATED EXTENSOMETER    Abstract An extensometer having two spaced-apart mounting bases adapted to be mounted on a load-bearing structure with its axis of sensitivity intersecting the axis along which load-induced strains are generated at 45°.  The extensometer includes a pair of parallel links connecting the mounting bases through respec-tive flexure hinges.  In one embodiment, one of the links is also connected to one of the bases through an intermediate flexure hinge so that the link deforms responsive to relative movement applied between the bases along the axis of sensitiv-ity.  A strain gauge mounted on this link measures the magnitude of the deformation.  In a second embodiment, a strain-instru-mented measurement beam extends between the two links so that it deforms responsive to pivotal movement of the links as the mounting bases move in opposite directions along the axis of sensitivity.  This embodiment of extensometer may be mounted on the load-bearing structure through three or more mounting points.  In order to facilitate mounting of the extensometer on a structure without pre-straining the extensometer, a rigid plate may be connected to the extensometer through a plurality of pins, each of which extends from the plate through the extensometer at each of the mounting points.  The pins terminate in a point and they are biased against the structure by a threaded fastener extending from the plate, through the extensometer, and into the structure.

Abstract: DUPLICATED NETWORK ARRAYS AND CONTROL FACILITIES FOR                   PACKET SWITCHING            Abstract A communication method and packet switching system in which packets comprising logical addresses and voice/data information are communicated through the system by packet switching networks which are interconnected by high speed digital trunks with each of the latter being directly terminated on both ends by trunk controllers. During initial call setup of a particular call, central processors associated with each network in the desired route store the necessary logical to physical address information in the controllers which perform all logical to physical address translations on subsequent packets of the call.  Each network comprises duplicated arrays with each array having stages of switching nodes which are responsive to the physical address associated with a packet by a controller to communicate this packet to a designated subsequent node.  Each trunk controller alternately transmits packets to available ones of the duplicated arrays as the packets are received from the attached trunk. If an array is unavailable for a time interval specified at initialization time by the associated processor, an affected trunk controller detects and transmits this fact to the associated processor via a maintenance message. Each trunk controller provides variable packet buffering and signaling protocols for each of the arrays in order to facilitate the transfer of packets from the arrays to the attached trunk.

ABSTRACT OF THE DISCLOSURE           An auger assembly particularly useful for transporting materials such as fertilizer which can com-pact and plug the auger, includes a slide arrangement mounting the motor, shaft and flight for sliding move-ment relative to the tube so that the end of the flight at the feed end of the tube can be withdrawn into the tube and latched.  The movement is obtained from rever-sing the direction of the drive motor to screw the flight upwardly in the tube which is then latched at the upper position.  The flight and tube can then be emptied of material so that jogging movement caused in transporta-tion does not cause compaction of material against the flight.  A shroud over the upper end of the tube is car-ried by the motor and is slidable therewith.

Abstract: ABSTRACT OF THE DISCLOSURE     Vehicle-borne apparatus for spraying liquid completely around immoveable upstanding objects such as trees or poles.          The apparatus comprises an articulated boom having a pair of normally aligned, linear members.  These members are secured to each other so that during operation the outer member can pivot out of alignment about a vertical axis in a direction opposite to the direction of motion, against the force of biasing means urging that member back to aligned position.  A spray head is rotatably secured  to the front  end of the outer member,  to rotate about a vertical axis at the center of the head.  The head has a plurality of arms with spray nozzles at their ends, radially  and  outwardly  extending  from  its  center.   Adjacent arms form angles of 90° or more with respect to each other and receive between them a portion of the immoveable object.  This device is particularly useful for herbicidal spraying of a line of trees, as in a orchard, enabling spraying completely around the base of such trees from a single pass of a tractor carrying the apparatus along one side of such a row of trees.
