Abstract: ABSTRACT   A process and system for combusting a nitrogen-containing fuel to produce low NOX levels in the exhaust emissions. A stream of the fuel mixed with air is combusted in two or more fuel-rich zones having catalytic beds. The stoichiometry of the mixture in each zone is controlled for the particular catalytic material employed so that a minimum of NOX precursors is formed upon combustion in the zones. Additional air is injected into the flow to maintain the predetermined stoichiometry in the downstream zones. The beds of the fuel-rich zones can be comprised of different catalytic materials having different theoretical air proportions at which the NOX precursors are at a minimum. The beds of the fuel-rich zones can also be comprised of the same catalyst material having different minima at which NOX precursors are formed at different theoretical air proportions. A final zone combusts the exhaust products at a stoichiometry of at least 100% theoretical air to substantially complete combustion of fuel. Means can be provided for extracting heat from the flow between the combustion zones.

Abstract: ABSTRACT     Conventional digital modems have not been applicable to pacemaker telemetry systems since their use would require the periodic conversion of analog data to a numerical value prior to transmission.  In contrast, the pulse interval telemetry system of the present invention is capable of transmitting analog data without conversion to a numerical value, and is capable of sequentially transmit-ting both digital and analog data.  This data is individually and serially trans-mitted in either an analog or digital format to a remote receiver.  The apparatus of this invention includes a resonant tank circuit for producing a radio frequen-cy carrier signal.  This tank circuit is operative at periodic intervals deter-mined by the output frequency or period of a variable frequency oscillator (VFO).   Thus, the VFO output modulates the time interval between consecutive pulses of the carrier signal.  Sources of digital and analog information are interfaced to the VFO to vary the VFO output period.  In the digital mode the VFO output is varied to a first preselected period to encode a logic one) and to a second pre-selected period to encode a logic zero.  In the analog mode the VFO output is continuously variable over a limited range about a nominal time period to encode the analog data.  An additional feature of the invention is the use of the VFO output to synchronize the translation of digital data from a parallel format in memory to a serial format suitable for telemetry transmission.

Abstract: S P E C I F I C A T I O N          "Fitments for Containers from which Liquid is Intended to be Withdrawn by a Hollow Needle or Tube"          ABSTRACT OF THE DISCLOSURE            A container provided with a self-sealing closure member, through which a needle may be inserted to withdraw liquid from the container, is fitted with a sterilizing cap.  The space within the upper region of the cap is divided into compartments by partitions, and each of the compartments contains a sterilizing substance. On withdrawal of a dose of liquid from the container a needle is caused to penetrate a weakened region of the cap and to pass through one of the compartments prior to penetrating the closure member and being introduced into the liquid within the container.  After the appropriate dose has been taken up the needle may be withdrawn.  The needle is coated with sterilizing substance both on introduction of the needle into the container and on withdrawal of the needle, and this serves to present contamination of the liquid within the container by the needle as well as infection of the site of injection where the needle is subsequently used to perform an injection. After the needle has been passed through one of the compartments a number of times, it may be passed through another of the compartments which contains fresh sterilizing substance.

Abstract: Abstract A mixture of vinyl plastisol, suspension grade resin and expanded perlite is prepared in a manner such that the particles of perlite are not significantly damaged.  The mixture is placed on a substrate and fused, thereby producing a foam-like material which is usable as a decorative covering.  Alternatively, the mixture can be cast on a release surface and allowed to stand until the majority of the perlite particles have migrated to the top surface, thus leaving a layer of material containing substantially no perlite along the lower surface which interfaces with the release surface.          Upon fusing this stratified mixture and separating the release surface, the fused material is inverted.  The layer of material which contains substantially no perlite becomes the protective surface and the remaining portion of the fused material, which is foam-like in nature, becomes the resilient support.  Such syntactic foams may be used as replacements or substitutes for mechanically frothed of chemically blown foams.

Abstract: ABSTRACT OF THE DISCLOSURE      An intercarrier signal detection circuit for a television receiver sound system comprises a SAW (Surface Acoustic Wave) filter coupled to the output of a tuner, the SAW filter having a response characteristic including two symmetrical lobes cantered about 41.25 MHz and 45.75 MHz respectively.  The signal developed at the output of the SAW filter is applied to an AGC          - controlled IF amplifier and then separated into a 41.25 MHz sound IF component  and a 45,75 MHz picture IF component.  The 41.25 MHz sound IF component is applied to one input of a synchronous detector whose other input is injected with a carrier signal developed by a phase lock loop operated in response to the 45.75 MHz picture IF component.  The synchrunous detector thereby produces a relatively clean 4.5 MHz intercarrier sound signal which is preferably enhanced by causing the injected carrier signal to exhibit a quadrature phase relationship with any 45.75 MHz picture IF remnants characterizing the separated 41.25 MHz sound IF component.  The 45.75 MHz picture IF component and an amplitude limited representation thereof developed by the phase lock loop, are coupled to respective inputs of an additional detector for developing a baseband video signal which is used by an AGC circuit for controlling the gain of the IF amplifier.
