Abstract: SAWMILL  APPARATUS     Abstract of the Disclosure A log is moved forwardly in a longitudinal path through a saw while engaged between a pusher dog and a hold-back dog.  The dogs are supported respectively by a pair of endless carriers which are parallel and adjacent to each other on one side of the log path.  The log is scanned and rotationally oriented before being engaged by simultaneous forward movement of the pusher dog and rearward movement of the holdback dog. Forward movement carries the log first to a chipper head and then to a guide surface which engages the face cut by the chipper head for stabilizing the log during sawing.

Abstract: DATA COMPRESSOR                  ABSTRACT OF THE DISCLOSURE   A data compressor with a plurality of serially connected shift registers compressing digital signals received from a data lift for transfer to a storage device which operates at a slower rate than the data lift generates digital signals. The data compressor eliminates from the data stream one of the frequently generated digital signals or a closely related group thereof and substitutes an address of the next digital signal which is not of the group being eliminated. Further, the data compressor eliminates trains of redundant signals which are longer than a certain minimum number of signals and substitutes a count which represents the number of redundant signals within each train therefor. The data compressor also inserts control markers into the data stream to identify the redundancy counts and the addresses which have been inserted therein. A logic sequencer controller is provided within the video data compressor controlling the elimination of data from the data stream and the insertion of the control markers, addresses and redundancy count therein.

The method provides for delivering brine or the like to a plurality of liquid directing nozzles at a pressure of about 21.1 kg/cm2(300 psi) and distributing the liquid onto the frozen water from the nozzles as coherent laminar streams having a turbulent outer boundary layer. The streams of liquid are directed at an incident angle of between about one to 5 degrees to the layer of frozen water. Preferably, the streams of liquid are also directed at a heading which defines an acute angle with the direction of movement of the nozzles. The apparatus, which is adapted to be mounted on a truck or other ground vehicle, includes a liquid storage tank, a high pressure liquid pump, a distribution header having a plurality of nozzles connected thereto and conduits interconnecting the foregoing. A nozzle support undercarriage supports the header and nozzles beneath the truck above the frozen water surface. The header is adjustable on the undercarriage to correctly orient the nozzles.

Abstract: ABSTRACT       An alarm system in which local transmitters emit sub-stantially pure acoustic signals for at least a predetermined minimum interval.  The receiver includes a microphone and amplifier for transducing the acoustic signals into electrical signals.  These electrical signals pass through two bandpass stages, the second being a phase locked loop circuit.  An RC timing network is connected to the second bandpass circuit.          After about 7500 cycles of the electrical signal have been received an "alarm received" signal occurs.  The "alarm received" signal is applied to the triggering input of a free-running pulse generator which supplies pulse trains to a counter and is itself halted when the counter reaches a first intermediate state.  A second "alarm received" signal is required to restart the free-running puIse generator and thus advance the counter beyond said first intermediate state.          Thereafter, when the counter reaches a second intermediate state, the occurrence of the corresponding second intermedi-ate state signal actuates a suitable alarm signal to warn of intrusion or some other hazardous condition.

Abstract: RCA 73,018 Abstract A synchronization signal separator circuit is provided for separating the synchronizing signal components of a composite video signal.  A composite video signal containing negatively-directed synchronizing pulse compo-nents is coupled to one input of a differential amplifier comprising two transistors of one conductivity type, and to the base electrode of a peak detector charging tran-sistor of opposite conductivity type.  The charging transistor charges a peak detecting capacitor to a reference level which establishes the slicing level of the sync separator.  The base-to-emitter voltage of the charging transistor offsets the slicing level by one Vbe relative to the sync pulse tips, thereby ensuring that the slicing level is offset from the sync tip level.  The peak detecting capacitor is coupled to a second input of the differential amplifier, where the slicing level is compared with the composite video signal for separation of the sync pulses.  A current source resistor is also provided, which is the sole source of charging current for the peak detecting capacitor between sync pulse intervals.  The charging current allows the slicing level to vary so as to follow changes in video signal level.  A sync separator recovery circuit is provided which is keyed to cause the slicing level to change rapidly in response to sudden changes in signal level.

The solvent, which has a lower boiling point than the temperature at which the hot water is maintained, boils off from the polymer product, solvent and water composition and leaves the d???red, finely divided, polymer product admixed in the water phase.
