Abstract: Abstract A pneumotachograph including a housing having first and second ports which, during the course of respiration, alternate as input and output ports and which provide a path for generally linear flow of the respiratory bases.  A pair of pitot tubes are di posed along the top of said path and are positioned generally at right angles thereto.  A pair of baffles or flow deflectors are disposed in the path in alignment with the axes of the pitot tubes.  Each of the baffles is positioned at an angle of approximately 45° to the axis of its associated pitot tube and to the path of flow.  The baffles serve to reflect the respiratory gases upwardly toward the pitot tubes but since the pitot tubes are arranged above the baffles gravity prevent. the heavier mucus, water and nongaseous materials from entering the pitot tubes.  Rather, these heavier particles run up to and over the top of the baffle.  The baffles may be held in the flow path by a rigid connection or alternatively, they may be retained there by a resilient connection such that the pitot tube measurement is linearized.            In another embodiment, the baffles may actually be merged into a single baffle thus leaving an annular opening between itself and the housing with the opening of the gap being approximately the same distance as the distance between the pair of tubes.  here the mode of operation is a pressure build-up upstream in proximity to the one tube and then a venturi effect downstream for lower pressure in proximity to the other tube.

Abstract: ABSTRACT OF THE DISCLOSURE         A billing recorder for providing a record of customer usage of electricity has a controller which may include a microprocessor for receiving and processing pulses from an electric meter.  Data from one or more input channels is temporarily stored in random access memory by the controller in data words representative of energy consumed in predetermined time ("demand") intervals.  The accumulated measurement ("event") data and time reference data are transferred to a non-volatile, solid state memory at the end of rel-atively long collection periods which comprise a number of demand intervals. The solid state preferably is energized by the controller only during data transfers.  The entire memory module is removable for processing at a central location, and it is replaced with a new one when it is removed.  During mem-ory replacement, which may occur at most times with minor exception, the processor prepares a special Removal Record and transfers that record to pre-determined locations on the memory module being removed.  The processor also prepares a special Insertion Record for the new module.  The cumulative counts recorded on these special records as well as the normal records estab-lish reliable data continuity.  A field test enables testing of the meter, data inputs and processing circuitry in the field.  Further, the identifica-tion data (I.D.) may be set on the recorder in the field after installation or replacement.  Provisions are made for incorporating various options such as Daylight Savings Time, one or two input channels and operation on 50 or 60 Hz. line frequency.

Abstract: A B S T R A C T     One of the problems commonly associated with needle valves is the danger of the valve coming apart  in response to rotation of the needle valve to the open position. This problem is overcome by the present invention in which a travel body is threadedly mounted in its valve stem passage so as to tighten against the main body of the valve in response to rotation in a first direction and to be  releasable in response to rotation in a second direction. The valve stem is threadedly mounted in the travel       -body for rotation relative to the travel body so as to close the through passage by movement towards the valve seat in response to rotation in said second direction and to open the valve passage in response to rotation in the first direction. A packing lock nut is mounted on the valve stem and adapted to threadedly engage the travel body for rotation in the first direction into locking engagement with the travel body and rotation in the second direction to be released from the travel body. Packing is provided on the valve stem between the travel body in the packing lock nut for scaling the valve stem when the packing lock nut is locked with respect to the travel body.

Abstract: PROGRAMMABLE I/O DEVICE IDENTIFICATION                 Abstract of the Disclosure A computer system having a CPU connected to I/O devices via a channel for setting addresses into the I/O devices by the CPU.  The I/O devices for purposes of control are grouped in types.  To load device addresses or identifiers, the processor sends a type identifier to the I/O devices.  The highest ordered device in terms of priority which does not have an assigned identifier responds by inhibiting all lower ordered devices of its type.  It is then loaded with its unique assigned identi-fier which results in the setting of its status latch. This setting allows the next lowest ordered device to then be assigned and loaded with an identifier by the pro-cessor.  This process continues until all I/O devices of the same type are loaded.  The process is then repeated for each other type of I/O devices.
