Abstract: ABSTRACT A radio broadcasting system with code signaling where-in a multiplex signal frequency-modulated on a main carrier is transmitted at the transmitter side. The multiplex signal con-tains an audio frequency information and, in the case of stereo transmission, a stereo information signal modulated on a sup-pressed sub-carrier and a stereo pilot, which serves for de-modulating the stereo information signal, whose frequency is loc-ated between the frequency spectra of the audio frequency in-formation signal and of the modulated stereo information signal. The multiplex signal also contains a binary code signal which is modulated on a further sub-carrier located outside the frequency spectra of the audio frequency information signal and having an amplitude which causes the main carrier to deviate for not more than 1 KHz. The further  sub-carrier is a harmonic of a sub-harmonic of the stereo pilot not coinciding with a harmonic of the stereo pilot and is derived at the transmitter side form the same frequency source as the stereo pilot. The code signal is binary phase modulated on this sub-carrier.

Title: Small dimension low frequency folded exponential horn  loudspeaker with unitary sound path and loudspeaker system including same
Inventor: KLIPSCH PAUL W
IPC: H04R3/14
Filed: 1978-06-01
Granted: 1981-03-31
Abstract: Abstract of the Disclosure A small dimension low frequency loudspeaker has a folded exponential horn which provides a unitary curved sound path from an electroacoustic transducer at the throat of the horn to a volume into which sound is radiated at the mouth of the horn.  The length of the horn is such that, at an exponential rate of expansion between the throat and the mouth, the mouth, when it is bounded by at least one planar surface, such as a floor, a ceiling, and/or walls of a room, has adequate area to enable reproduction of low audible frequencies.  An illustrative embodiment of the low frequency loudspeaker has an effective low end cut-off frequency of 55 Hz.  A loudspeaker system, including a low frequency loudspeaker as well as midrange and high frequency loudspeakers and an LC crossover network, is also disclosed.  The LC crossover network includes an autotransformer which not only serves as a component to determine a crossover frequency but which also boosts the electrical signal that is input to the electroacoustic transducer of a less efficient loudspeaker.  The autotransformer increases the output of the less efficient loud-speaker and accommodates its use with more efficient loudspeakers so that the overall loudspeaker system operates at optimum effi-ciency.  An illustrative embodiment of the loudspeaker system affords 108 dB SPL output at one meter with one watt input which corresponds to about 20% overall efficiency.  The smoothness of amplitude response over the range of audible frequencies that is necessary for high fidelity sound reproduction is improved by inclusion of peaking circuits in the LC crossover network of the loudspeaker system to enhance amplitude response in the regions of crossover frequencies.  Side wings are additionally provided to eliminate cavities at the sides of the loudspeaker system which would otherwise cause deterioration of smoothness of amplitude response.

Abstract: PRONGED VIBRATOR     ABSTRACT         A vibrator with attached prongs which achieves the breakup of compacted materials in structures similar to silos, grain elevators and railroad cars is set forth.  Attached to the pronged vibrator is a cable which allows the vibrator to be lowered into the structure where breakup is to be accomplished.       The vibrator is housed within a shell of dimensions applicable to the particular use.  Secured to the vibrator shell are a multiple of prongs.  The vibrator when in operation not only causes the sphere to vibrate, but also the attached prongs.  The vibrator is capable of imparting varying frequencies to the compacted materials and may be adjusted to reach the natural frequency of the compacted material.  Thus, where the vibrator comes into contact with the compacted material, breakup is achieved both by the physical action of the prongs and also achieving the natural frequency of the material which in and of itself causes breakup.

Abstract: ABSTRACT Method and apparatus for improving contour repro-duction particularly of thin lines and serifs for engraving rastered printing forms, where the engraving of the cups arranged in a printing screen is carried out by electromag-netic engraving means which is controlled by a raster signal. The image pattern to be reproduced is scanned point-by-point and line-by-line by opto-electrical scanning means with a resolution higher in the scanning direction than that of the printing screen and the image signal obtained is converted point-by-point into digital image values.  Based on the higher resolution additional intermediate image values are obtained between the principal image values which are produced with the frequency of the raster signal.  The principal image values and the intermediate image values are converted back into an analog image signal in the sequence of their creation, said image signal being superimposed on the raster signal with a time relationship to the amplitude values of the raster signal which determine the moments for the engraving of the cups by the engraving tool of said engraving means.  Thus, for a contour in the image pattern to be reproduced, two partial steps of the image signal are produced during a particular time interval rather than a single larger step (prior art).  The first partial step, corresponding to the intermediate image value of the contour, is superimposed onto the raster signal prior to said amplitude value of the raster signal and the second partial step, corresponding to the principal image value of the contour, is superimposed onto said amplitude value of said raster signal.  Whereby the cups representing a contour on the printing form are shifted toward the high level of density of the contour, thus, the contour is improved.

Abstract: LIMITED FLOAT SEAT CONSTRUCTION FOR      EXPANDING GATE VALVE            Robert J. Diehl Vivian, Louisiana Robert C. Houlgrave Houston, Texas Abstract of the Disclosure A limited float or controlled float seat assembly for a gate valve with a transversely expandable gate assembly has generally L-shaped annular seat retainers fixed in recesses around the valve inlet and outlet flow passageways and generally L-shaped annular seat members mounted in a complementary relation within each of the seat retainers. The seat retainers each have an inturned lip opposite to and spaced from the end of the recess. The inturned lips form limit stops for the seat members. The seat members have an outturned lip which contacts the inturned lip of the seat retainer thereby limiting movement of the seat member when the seat member moves to an extended position. The combined amount of float for both seat members is less than the total expansion of the gate assembly from a collapsed position to an expanded position where it seals with the seat members so that drag of the seat members on the gate assembly is minimized.

Abstract: LOCK MECHANISM     Abstract of the Disclosure There is disclosed a lock mechanism including a casing adapted to be mounted to a door or door frame.  The lock mecha-nism has been designed to take up a minimum amount of space and thus is accommodatable in a relatively shallow casing structure.          Said lock mechanism includes a latch bolt pivotally mounted for movement between a first position wherein a portion thereof extends from said casing and a second retracted position, asso-ciated with the latch bolt in a deadlock, also pivotally mounted and movable between a blocking position wherein said deadlock will prevent retraction of the latch bolt from its first position, and a non-blocking position wherein said latch bolt is free to move to said retracted position, with biasing means urging said deadlock toward said blocking position.  To control the opera-tion of the deadlock, a deadlock trigger is mounted to said casing and is movable between an extended position wherein a portion of said trigger extends from said casing, and a re-tracted position.  A deadlock position lever provides the opera-tional connection between said trigger and the deadlock, said lever being pivotally mounted with respect to said casing, and including a first end portion operatively associated with said deadlock trigger, and a second end portion operatively asso-ciated with said deadlock, such that when said trigger is in the extended position, said deadlock lever will be biased to a position wherein said second end portion will effect movement of said deadlock to said non-blocking position with respect to the latch bolt, with movement of said trigger to the retracted position, freeing said deadlock for movement to the blocking position.
