Abstract: IMPROVED VECTOR KVA METER           ABSTRACT OF THE DISCLOSURE           A meter apparatus for determining Vector VA demand, and other electrical quantities, over a predetermined time period t uses a watthour meter and a Q-hour meter with pulse initiators.  The time period is divided into a plurality of subintervals and the VAh or other quantity is determined for each subinterval .DELTA.t.  Thus  .DELTA.VAh is determined using the relationship   where .DELTA.Wh is the output from the watthour meter and .DELTA.VARh is a value for .DELTA. VAR hours determined generally from the relationship .DELTA. VARh =           where Qh represents Q-hours and 0 represents an angle by which the voltage vectors are rotated for measurement by a Q meter of Q-hours.  The values of .DELTA.VAh for the subintervals in the time period are summed to provide total VAh for the time period, and from which can be calculated the Vector VA demand for the time period.          By making the determination based on relatively short subintervals, the inaccuracies introduced by changing power factor over the time period are reduced or eliminated for all practical purposes.

Abstract: ABSTRACT OF THE DISCLOSURE      A chlorinated rubber having a chlorine content of about 5 through about 50% by weight and a Mooney viscosity (ML1+4 at 100°C) of about 20 through about 150 is presented.        This chlorinated rubber is derived from the chlorination of (i) a copolymer rubber of ethylene and 1-butene having a mol ratio of ethylene/1-butene of about 85/15 through about 95/5 or (ii) a copolymer rubber of ethylene 1-butene and 5-ethylidene-2-norbornene having a mol ratio of ethylene/1--butene of about 85/15 through about 95/5 and a content of the 5-ethylidene-2-norbornene of 20% by weight or less based on the weight of the copolymer.  The incorporation of the chlorinated rubber into a polyvinyl chloride composi-tion results in the remarkable improvement of the impact resistance and flexibility, both at a low temperature, of the polyvinyl chloride.

Abstract: A B S T R A C T         Disclosed is a measurement apparatus for measuring physical quantity, such as temperature, pressure etc., and providing corresponding measurement data suitable for trans-mission to a remote central location.  The physical quantity being measured is first converted to a frequency signal, either directly by an appropriate transducer or by a com-bination of an appropriate transducer and appropriate converter.  Counters are then used to convert the frequency signal to a corresponding digital quantity.  An appropri-ately programmed digital processor is then used to perform processing operations on the digital quantity to derive the measurement data.  In one embodiment, the apparatus includes an optical transceiver for converting the measurement data into corresponding optical signals for transmission via an optical fiber to a central processor.  The optical trans-mission system between the measurement apparatus and the central processor includes provisions for facilitating the detection and diagnosis of failures in the optical compo-nents of the system.  In another embodiment the measurement data is converted to corresponding current signals for transmission via a conducter to a remote central location.

Abstract: Mounting Ring Abstract A mounting ring is suited for installation in an opening in a wall or ceiling to provide support thereat for a device, such as a sensor.  The ring includes an annular frame with a pair of deformable retaining tabs extending therefrom for manual defor-mation into retaining engagement with the inner surface of the wall or ceiling.  Centering tabs may aid in centering the ring about the opening.  One or more antirotation tabs may extend from the frame into the wall or ceiling to prevent rotation of the mounting ring.  One or more support tabs on the frame are sized and positioned to longitudinally support a tubular device extending within the open-ing in the ceiling or wall.  The device may be pro-vided with a complementary supporting surface or shoulder.  Conveniently, the device is rotated about its longitudinal axis to bring its supporting sur-face into supported alignment with that of the mount-ing ring.  Such rotation may also serve, via the mounting ring support tab, to urge the device into engagement with the wall or ceiling.  Detents may be provided on the mounting ring to interact with the device and inhibit rotation of the device out of supported engagement with the mounting ring.

Abstract: TITLE: OXYGEN DELIVERY APPARATUS            ABSTRACT      An apparatus for delivering oxygen to a patient is preferably constructed so as to include an elongated, deformable receptacle having an open side extending along its length, a flexible, "floppy" diaphragm secured at its edge so as to seal off or enclose the open side of the receptacle and a retainer for protecting and for limiting expansion of the diaphragm located along the side of the diaphragm remote from the receptacle. As the apparatus is used, oxygen is constantly delivered to the extremities of the receptacle through appropriate supply lines. On exhalation exhaled gas is forced by the pressure of the breath through a cannula ? preferably a nasal cannula ? into the interior of the receptacle remote from the supply lines. This cannula is used so that gas can flow. This exhaled gas is used to force the diaphragm against the retainer, opening up the interior of the receptacle in an amount such that some of the exhaled gas will be held in the receptacle. This latter gas will gradually be replaced by the oxygen. On inhalation this mixture will be drawn through the cannula into the body as a consequence of the partial vacuum created during inhalation. This will have the effect of collapsing the diaphragm against the interior of the receptacle so as to substantially close off the interior of the receptacle between the cannula and the supply lines.
