Abstract: Abstract of the Disclosure This invention relates to apparatus for the detection of acoustic impact frequencies, characteristic of bearing assembly failure during operation, which modulate an acoustic carrier frequency band.    This apparatus allows for on-site or field application with high-level of ambient noise such as are present in railroad yards.    This apparatus allows for early detection of such failures, so that a repair may be made before damaging heat build-up or catastrophic bearing failure occurs.          Additionally, with sufficient early warning in railroad applications, a train may continue running to a railyard for convenient shop repair rather than expensive field repair.

Abstract: ABSTRACT             The present invention is a leaky cable which can be used as an antenna or as an intruder detector sensor either buried in a single trench or above ground and which substantially reduces sensitivity variations due to the environment.  This is effected by substantially blocking egression of the electric field from the cable but allowing magnetic fields to escape, and by substantially slowing the velocity of and attenuating the externally propagating electromagnetic field.  In the preferred embodiment, the leaky coaxial cable is comprised of an inner conductor, a dielectric surrounding the inner conductor, a first external shield having low series impedance at VHF frequencies surrounding the dielectric, means for coupling a magnetic field through the first external shield, a second external shield surrounding the first external shield having high series impedance relative to series impedance of the first external shield and means for limiting VHF conduction current between the shields, which effectively causes separation of the internal and external propagation fields of the cables.  The external shields are arranged so that the first external low series impedance shield does not short circuit the second external high series impedance shield, thus separating the internal and external propagating fields of the cable.  One way to achieve this result is to place a thin semiconductive or insulating sheath between the two shields.  A second way is to ensure that the skin depths at VHF in the two shields are adequate to effectively separate the two signals.  The external signal, propagating on the outside of the second external shield and the internal signal propagating on the first external shield are effectively separated thereby.

Abstract: ABSTRACT OF THE DISCLOSURE        A method and apparatus for compressing fibrous material into dense bales having uniform size, shape and weight.  Weighed longitudinally extended charges of material having a predetermined transverse dimensional profile are individually loaded into a compression chamber defined by side plates and first and second movable end platens.  A long-stroke small-diameter hydraulic piston pushes the first end platen against the charge toward the second end platen, partially compressing the charge.  The first end platen is then latched in a fixed position at full stroke while the second end platen, via a short-stroke large-diameter hydraulic piston, applies a further compressive force to the charge against the first end platen.  The resulting fully compressed charge is pushed out of the compression chamber, bound loosely while still fully compressed, then released, whereupon the bale longi-tudinally expands into the bindings to a predetermined length.  As the large-diameter piston retracts to begin the subsequent compression cycle, hydraulic oil is routed therefrom to other hydraulic cylinders to effect retrac-tion thereof, thereby lessening demand on the hydraulic pump, saving energy and reducing cycle time.

Title: Television tuning system allowing rapid response to user initiated commands
Inventor: RICHARDS ROGER L
IPC: H03J1/00
Filed: 1989-04-13
Granted: 1992-06-16
Abstract: RCA 85,002 Abstract The operation of a tuner of a television receiver for tuning nonstandard, as well as standard, frequency RF television signals, requiring a relatively long time for completion, is partitioned into a number of shorter duration sections or "slices" which are individually time-multiplexed with other control operations under the control of a microprocessor.  This allows the microprocessor to more frequently respond to new user initiated commands than otherwise possible.  An interrupt subroutine of the stored program under which the microprocessor operates establishes time delays, required for the tuning system to settle before new operations are performed, outside the main control loop including the user command processing and tuner control subroutines so as not to slow the response of the microprocessor to user commands.

Abstract: ABSTRACT      A data encoder is set to an initial condition by encoding preliminary symbols.  The encoder is then used to encode the data to generate ECC symbols.  The data and the generated ECC symbols are then recorded on a disk as code words.  Thereafter, when a data code word is read it is again encoded in the initialized encoder to generate new ECC symbols.  If the data read from the disk is one or more symbols out of synchronization, errors due to the initial condition will be found.   The locations of the errors due to mis-synchronization will be in symbols corresponding to the initial condition, that is, in the preliminary symbols and beyond the boundary of the code word data, indicating the synchronization error.  Alternatively, the locations of errors due to defects in the disk or misinterpretation of the data signal are within the code word data.  Thus a mis-synchronization of one of more full symbols can be readily detected.
