  • Patent number: 4566007
    Abstract: A two-stage, rearrangeable multiconnection switching network for connecting N.sub.1 input channels to n.sub.2 output channels. The network comprises a number of first stage switches and a second stage switch, e.g., rectangular arrays. The second stage switch has n.sub.2 outlets each connected to one of the n.sub.2 output channels. A connection arrangement connects each of the first stage switch inlets to an associated predetermined input channel such that for any group of n.sub.2 of the input channels, there is a group of n.sub.2 of the first stage switches each having one inlet connected to a different one of that group of n.sub.2 of the input channels. The approach is easily extendible to switching networks serving any larger number, N.sub.2, of output channels by adding second stage switches and connecting each additional second stage switch to each first stage switch. In larger networks, the first and second stage switches are themselves replaceable by two-stage networks in accordance with the invention.

  • Patent number: 4527267
    Abstract: A D-bit in an X.25 data packet access protocol flags whether an acknowledgment of packet communication can be local or must be end-to-end. The disclosed method with programmed processing handles the D-bit option by a two-sided memory table that couples the X.25 access protocol and the internal protocol of a packet switching network. The table, called rack.sub.-- perm (for Receive ACKnowledgment PERMission) is set with one entry per data packet sequence number. The rack.sub.-- perm entries are modified by the internal protocol in response to an acknowledgment packet received from the switching network. Checks are made of rack.sub.-- perm by the internal protocol using indices of the access protocol to determine the number of acknowledgment packets permitted to be sent to an originating data terminal equipment.

  • Patent number: 4524440
    Abstract: A fast circuit switching system that establishes a circuit for each packet-sized data communication. Information is conveyed from a number of communications modules in source channels to a number of port controllers and to a network. Information is conveyed from the network to destination channels. Each communications module includes a transmitter that transmits in an associated source channel, circuit setup request signals defining destination channels and also transmits data. Each port controller stores one of a number of status words defining the availability of the destination channels and each of these status words is cycled to each port controller. A port controller responds to one of the circuit setup request signals and to subsequent data, when one of the status words cycled thereto defines as available, a destination channel defined by the circuit setup request signal, by transmitting the circuit setup request signal and the subsequent data to the network.

  • Patent number: 4279032
    Abstract: A method of detecting analog signal degradations in channel bank apparatus. The apparatus interconnects a digital PCM line with a plurality of analog trunks by means of multiplex circuitry and a plurality of channel units each comprising a PCM-to-analog signal receive path and an analog-to-PCM signal transmit path. A plurality of sequences of prescribed PCM test code words, wherein each sequence is amplitude plottable against time into a triangularized waveform cycle, are circulated via a loop-around path bridging the receive and transmit paths of a channel unit.A set of values, each corresponding to a type of analog signal degradation, is derived for each recovered word sequence, based on prescribed amplitude and slope characteristics of its waveform plot, and is averaged over the recovered sequences. If any average characteristic value is not within an expected tolerance of a corresponding prestored expected average value, a defective channel unit indication is displayed.

  • Patent number: 4256100
    Abstract: An anesthesia ventilator is disclosed for controlling the flow of air and/or oxygen through a plurality of binary weighted valves from a fluid regulator source to a bellows assembly. Directly-set minute volume, breath rate and inspiration to expiration ratio controls operate electronic circuitry which adjusts the magnitude of the flow, the tidal volume and the inhalation to exhalation times. The circuitry includes alarm detecting devices for alerting personnel that a patient should be ventilated manually, that a patient is disconnected from the instrument, that control settings exceed specifications for the instrument, that undesired low gas pressure exists and that actual inspiration to expiration is less than that of the control setting. Flow and tidal volume limiting apparatus is provided, together with sigh circuitry and devices for correcting for altitude and gas parameters.

  • Patent number: 4205624
    Abstract: This specification discloses a procedure and facilities for removing animal excretions from rubber particles used as stall bedding material for animals, such as horses. The procedure involves vacuuming the bedding material into a drum container and then wheeling and securing the filled container onto a skip-hoist of the sanitizing equipment. The hoist raises the container and deposits its contents into a holding hopper from which they are fed through a meter at a uniform rate onto an orbiting screener. The orbit movement and orientation of the screener segregates the animal excretions and hay from the rubber particles. The latter are steam cleaned and then fed onto a leaf-type vibrating screener for drying, sanitizing and insecticide spray coating. The sanitized particles are next vibratorily moved off the screener into a collecting drum. Waste extracted from the two screeners is conveyed onto an inclined platform for migration toward a waste collector.

  • Patent number: 4161878
    Abstract: A fluid flowmeter includes a bluff body for producing vortex shedding free of intermittency. The body has at one end a support member for mounting in a conduit and has proximate its downstream surfaces a pair of orifices. A vibratory planar sensor, preferably ferromagnetic, is situated in a sensor chamber within the support member for vibrating in response to received pressure fluctuations. A magnetic detector is situated in proximity to the sensor for producing an electrical signal when the sensor vibrates in response to vortex shedding. Fluid in the conduit, and thus vortex shedding, is coupled from the orifices through a pair of parallel channels, which are in non-fluid-flow communication with one another, to opposite sides of the sensor. In one embodiment, the sensor comprises a diaphragm rigidly mounted along its periphery whereas in another embodiment the sensor comprises a rigid, substantially planar disc vibratorily mounted along its periphery.

  • Patent number: 4162377
    Abstract: A method is disclosed for automatically processing call data from a TSPS (Traffic Service Position System) over CCIS (Common Channel Interoffice Signaling) facilities to a remotely located data base system to verify the entitlement of the caller to bill the call on a credit card, collect and charge-to-a-third number basis. The call data is dialed by the caller and comprises a credit card or station number together with a PIN (Personal Identification Number) used by authorized callers in placing the special service calls. The data base system includes a memory table of authorized numbers to which the calls are charged and billed. The data base transmits CCIS direct signaling verification messages through the signal transfer system to the TSPS signifying the entitlement and nonentitlement of the caller to the call service.

One side (20.3) is depressed to form a plateau (20.5), and a plate (20.6) covers the plateau to form a slot (20.7) into which a lower tread (18.3) of the bracket is inserted. The rectangular aperture is reversed into the base so that a riser (18.4) of the bracket fits into the aperture flush with the base when the lower tread is inserted into the slot. Snap fit means (20.8, 18.5, 18.6) is included on the end portions of the one side (20.3) of the support member to secure the lid therein. A protective coating (20.9) is provided on the inner surface of the other side (20.2) to prevent the outer surface of the lid from being marred.
