Abstract: ABSTRACT OF THE DISCLOSURE       A digital waveform generating apparatus includes a key assignor selecting a frequency of a signal to be generated, a number-setting circuit for generating a first data word cor-responding to the selected frequency, a first memory for storing said first data word, a second memory for storing a second data word, an accumulator for accumulating the first data word onto the second data word stored in the second memory, so that the second data word stored in the second memory after accumulating represents the sum of the second data word immediately prior thereto added with said first data word, a waveform memory, preferably an ROM, for storing predetermined waveform data and for generating a waveform data output signal, and a control circuit for controlling such accumulating and progressively addressing the waveform memory in accordance with the stored second data word at the time of a timing signal.  Preferably, the number-setting circuit generates a plurality of the first data words corresponding to at least one corresponding frequency, the first and second memories have a plurality of channels storing the first data word and the second data words  to be added with the first data words, and the control circuit operates in a time-sharing fashion.  To avoid folded errors in the output signal, the waveform memory can include a plurality of data banks each storing waveform data corresponding to a predetermined portion of the frequency range of the apparatus, and the control circuit operates to select an appropriate data bank corresponding to the selected frequency.

Abstract: ABSTRACT OF THE DISCLOSURE          Disclosed is a signal detector including a bank of digitally synthesized narrowband filters all having the same shape of frequency response and differing only in center frequency and which are imple-mented by time domain data processing.  The invention is comprised of: a signal conditioner, an envelope weighting computer, a Fourier trans-form processor and a post-detection processor.  Resulting therefrom is a bank of 16 contiguous narrowband filters having high selectivity along with a corresponding bank of envelope detectors of wide dynamic range which incorporates center frequency acquisition and tracking.          Following detection, a matched filter capability is included to provide correlation and data regeneration so that coded FSK data burst signals can be extracted in real time from noise, interference, and jamming signals which would otherwise affect signal detection.

Abstract: (Case No. 59-3) ABSTRACT    A hydraulic tensioning device and arrangement which maintains a predetermined amount of tensioning force on an end-less drive belt of the vehicle accessories drive system.  A hydraulically actuated piston applies a predetermined force to one of the vehicle accessories which is pivotally mounted with respect to the engine to tension the drive belt which is drivingly con-nected to this vehicle accessory.  A self-contained hydraulic fluid supply and pump assembly is mounted in a fixed position on the vehicle engine and has a fluid pressure line connected to the piston for hydraulic actuation of the piston.  An idler pulley is rotatably mounted on the fluid supply and pump assembly and is engaged with and driven by the drive belt for actuating the pump to supply hydraulic fluid from the fluid supply to the piston. A coil spring mounted within the piston cylinder applies a portion of the tensioning force on the belt tensioning accessory with the major portion of the tensioning force being applied hydraulically. Check valves regulate the amount of hydraulic force which is applied to the piston and ultimately to the belt by controlling the flow of hydraulic fluid to and from the piston.

Abstract: TURNER-l HIGH CAPACITY ELASTIC STORE HAVING     CONTINUOUSLY VARIABLE DELAY                 Abstract A commutator-type data store is serially connected to a variable length shift register.  Data is first written in the commutator store at the incoming varying line rate.  A predetermined time later, the stored bits are read out from the commutator-type store and stored in the shift register at a given rate.  Finally, the shift register data is read out at a constant predetermined rate.  The length of the shift register is controlled by a counter.  The phase relationship between the commutator write and read cycles is monitored by logic circuitry within the control unit.  If this phase relationship has increased by a preselected amount, the commutator readout rate is increased along with the length of the shift register. Alternatively, if the phase relationship has decreased by a preselected amount, the commutator store readout rate is decreased along with a decrease of the shift register length.

Abstract: "REEL ASSEMBLY FOR SWATH PICK-UP HEADERS OF COMBINES" ABSTRACT OF THE DISCLOSURE           Many present day combines utilize a swath pick-up header instead of the cutter bar component.  When picking up swaths of crop such as flax, oats, faba beans or the like, which are relatively slippery, the swath often tends to ride above the pick-up fingers and not enter the combine but to build up above the feed auger.  Also chaff and fine straw tends to build up at each end of the transverse feed auger all of which often chokes the entrance and prevents effi-cient feeding of the swath to the combine threshing compon-ent or concave.  The present device eliminates these faults by providing a rotatable beater assembly situated above the pick-up and forwardly of the transverse feed auger with the lower periphery thereof being preferably slightly below and in advance of the feed auger thus forcing the swath down-wardly and into engagement with the feed auger and prevent-ing overriding from taking place.
