Abstract: ABSTRACT OF THE DISCLOSURE.         To improve reliability of recognition of an announcement recognition (AR) signal radiated by a transmitter upon broadcasting an announcement (e.g. traffic information, news, etc.), in the form of AM modulation of a 57  kHz auxiliary subcarrier, in which the subcarrier may also be modulated by other control signals, the subcarrier is filtered in the receiver,  demodulated, and the degree of all modulations, regardless of frequency, on the subcarrier is sensed, and if the modulation changes significantly, for example rises from 60% modulation to 90% modulation (50% change), a switch (4) is activated which inhibits transmission of audio programs from an external source, such as a tape recorder, (5) tuner tuned to another station, or the like, and reproduces the announcement being broadcast; termination of the AR signal, forming the AR modulation on the subcarrier, causes the switch to revert for reproduction of previously controlled audio information.

Abstract: ABSTRACT OF THE DISCLOSURE An improvement is provided in a process and apparatus for in-line slush making, for use in, for example, concrete cooling. The improvement comprises connecting the inlet used to convey liquid such as water to the manifold section of the lance so that its longitudinal axis forms an acute angle with respect to the longitudinal axis of the inlet for introducing a cryogen into the lance. This improvement substantially eliminates failure to properly make slush due to a build-up of ice within the means used to control the flow of cryogen to the system. Additional improvements to the apparatus comprise substantially aligning the sealed head of the manifold with the longitudinal axis of the inlet for conveying the liquid to the lance to eliminate and to prevent freeze-up of the liquid in the dead space found in the "T" lance design of the prior art.

Abstract: VALVE ASSEMBLY                 Abstract of the Disclosure A valve assembly is provided for controlled draining of a liquid accumulated in a closed vessel.  The assembly includes a body member mounted on the vessel and a valve piece adjustably mounted on the body member for movement between open and closed positions.  The body member has a first sec-tion extending into the vessel interior wherein the liquid accumulates, a second section secured to the vessel, and a substantially exposed third section.  The first, second, and third sections are provided with a common primary passage and an independent common secondary passage.  Each passage has one end terminating within the vessel interior and a second end terminating externally of the vessel.  The body member first section is provided with a stationary valve seat disposed in aligned and spaced relation with respect to the primary passage one end.  The valve piece includes an elongated first element slidably and sealingly mounted within the primary passage.  A longitudinally extending bore open at opposite ends is formed in the first section.          One end of the bore engages the valve seat and is closed thereby when the valve piece is in a closed position.  An exposed flange element encompasses the exterior of the first element and is connected thereto.  The flange element is provided with a seal means which sealingly engages and closes off an end of the secondary passage except when the valve piece is in the open position.  The seal means effects a predetermined delay in opening the secondary passage relative to the unsealing of the bore end with respect to the valve seat.

Abstract: ABSTRACT OF THE DISCLOSURE      A pen recorder has a carriage movable across a sheet of print paper and supporting a rotatable drum with a plurality of pen units mounted thereon.  The carriage is movable between a pair of side frames through a print region and a nonprint region.  When the carriage is moved by a stepper motor into abutment against one of the side frames which provides a stopper position, the relationship between the phase of the stepper motor and the position of the carriage is determined.  Each time a print cycle is finished, the carriage is returned to a home position which is at the other end of the nonprint region.  A desired pen unit can be selected by reciprocating the carriage in an interval within the nonprint region, the interval being spaced from a preset number of increments of angular movement of the stepper motor.

Abstract: ABSTRACT OF THE DISCLOSURE      In accordance with an illustrative embodiment of the present invention, a full-bore drill stem testing system includes a lower housing member having a ball valve for opening and closing a flow passage extending axially therethrough and an upper housing member having an open axial bore in communication with said flow passage. Downwardly facing recesses are formed in the wall of the upper housing member laterally offset from the open bore, and each recess receives an electrical contact that is connected with transducer means for sensing variables such as pressure and temperature of well fluids below the ball valve.  Guide slots having orienting surfaces at their lower ends lead upwardly to each recess.  A running tool that is lowered into the upper housing member on electrical wireline has normally retracted arms which carry electrical contacts on their upper ends.  The running tool is actuated upon engagement with a stop shoulder in the upper housing member to cause extension of the arms, whereupon the running tool is shifted upwardly to cause the upper ends of the arms and the contacts thereon to be oriented and guided by the slots into engagement with the contacts in the recesses.  The electrical connections thus made enable surface readout of the downhole measurements as the drill stem test proceeds.

Abstract: ABSTRACT OF THE DISCLOSURE     A pattern processing system associates image input patterns with desired response codes.  The image input is stored in an image buffer as an addressable array of sample values.  An address sequencer provides an address stream containing a plur-ality of interleaved sequences of addresses to the image buffer and to a read/write response memory.  The next address of each sequence provided by the address sequencer is based upon the current address of that sequence and the state of the sample value stored in the image buffer at the location corresponding to the current address.  Once the address sequencer repeats an address in a sequence, that address sequence is in a repetitive address loop as long as the image stored in the image buffer remains constant.  During a training mode, a pattern to be recognized is supplied to the image buffer and a training code representing a desired response is written into the response memory at selected locations that correspond to addresses in the address loop being generated.  During a later recognition mode, when the same pat-tern is supplied to the image buffer, the same address loop is again generated.  The previously stored training codes are read from the response memory.  A response detector forms a histogram of the codes read out during an integration interval.  Based upon this histogram, the response detector provides a response code output representative of the pattern based upon the most frequent code (or codes) read out from the response memory.
