Abstract: ABSTRACT OF THE DISCLOSURE           Baling apparatus including a baling chamber and a compression ram mounted for reciprocal movement therein and a bale strapping chamber positioned adjacent the baling chamber.  The cycle is started by positioning a strapped bale in the strapping chamber between upper-and lower platform members.  Bale material such as newspapers and cardboard is introduced into the baling chamber and the compression ram is reciprocated to progressively form a bale against one end of the strapped bale in the strapping chamber.  During such bale forming operation the newly formed bale is gradually pushed between the upper and lower platform members to thereby force the strapped bale out from between such platform members on; to a take-away conveyor.  A pair of pivotally mounted gate members are mounted on opposite sides of the baling chamber at the exit thereof.  The take-away conveyor can be tilted to separate the adjacent ends of the unstrapped and strapped bales.  After the strapped bale has been completely pushed from the strapping chamber and separated from the unstrapped bale, the gate members are pivoted to retract position to expose all four sides of the completed but unstrapped bale in the strapping chamber.  A strapping mechanism is then actuated to progressively install a series of horizontal straps tightly around the bale.  When the bale has been completely strapped, the side gates are pivoted back to their closed position and the operation described above is repeated.

Abstract: ABSTRACT OF THE DISCLOSURE         A thermoparticulating tape is disclosed which com-prises a flexible fibrous material, a compound which thermo-particulates at a temperature below 200°C dispersed through-out the flexible fibrous material, and a flexible outer coating over the flexible fibrous material through which the products formed when the compound thermoparticulates can pass.  The tape is best made by dissolving the thermoparticulating compound in a solvent, immersing the fibrous material in the solution, evaporating the solvent, and applying the outer coating to the fibrous material.  An adhesive backing can be applied to the tape if desired.  The tape is placed in an electrical apparatus cooled by a gas stream, in a position exposed to the gas stream.  When overheating occurs the tape darkens and emits particles into the gas stream which are detected by a monitor.

Abstract: DIGITAL SPEECH COMMUNICATION SYSTEM              Abstract of the Disclosure A digital speech communication arrangement includes apparatus for partitioning a speech signal into a plurality of nonuniformly related, preassigned intelligibility contributing subbands.  Each subband portion is digitally encoded after sampling at a rate related to the bandwidth of the subband. The digital codes of the subband are combined and applied to a common communication channel.  A replica of each subband is formed by separating the digital codes, producing a sampled form of each digital coded signal and selecting the subband of the speech signal from said sampled form.  The subbands are combined to reconstruct the speech signal.  Other features include:  aliasing for efficient frequency transposition.

Abstract: Abstract of the Disclosure:         Circuitry for developing a binary number pro-portional to the frequency of an input signal includes a first and second shift register and an adder.  Timing control circuitry establishes a 16 bit computation period and also develops a fixed binary number.  Circuit means are provided for interconnecting the adder and the first register for increasing the content of the register by the fixed binary number once each cycle of the input signal to be measured.  Thereafter the content of the register is reduced by a fixed proportion of its content during each of a plurality of computation periods to cause the register to exponentially decay until the next input cycle is detected whereupon the process is repeated.  At the beginning of each cycle of the input signal the content of the first register is transferred to a second or buffer register where the data may be used to drive a gage or other output device.          The circuitry is particularly useful for processing a relatively low information rate signal such as often found in automotive speed transducers.  The prior art digital circuitry  requires a high information rate transducer in order to achieve a reasonable degree of resolution within a fixed time frame.

Abstract: ABSTRACT OF THE DISCLOSURE        Device for controlling draft in an oil burner furnace by governing an exhaust valve.  The device is provided with automatic, thermally responsive control disposed to increase or decrease the cross-sectional area of the passage at the valve as the temperature at the smoke flue decreases or increases, respectively.  Two sensors cooperate to govern the opening or closing of the valve; one of the sensors operatively transmits the instant temp-erature of the smoke flue, the other the instant temperature of the chimmney wall.  Increased fuel efficiency is obtained during the heating-up and normal operating phase of the furnace.
