Abstract: ABSTRACT OF THE DISCLOSURE      A power amplifier circuit is mainly composed of an amplifier including an input transistor, a driving transistor and a power amplifying transistor.  This power amplifying transistor is connected at its output end to an output trans-former the secondary winding of which is connected to a first adjusting means for adjusting an output impedance of the power amplifying transistor.  A second adjusting means, which is interlocked with the first adjusting means, is provided on the current path of the driving transistor to adjust the value of an emitter resistance of the driving transistor, and the biasing voltage of the power amplifying transistor is obtained from the current path of the driving transistor, thus the power consumption of this circuit being reduced by the adjustment of the first and second adjusting means.

Abstract: Abstract of the Disclosure This is a rotary loader system having one or more load frames mounted to travel around a central pivot post.          Each frame has a load support preferably two fork arms ex-tending radially out and curved in like a gear or sprocket tooth profile to mesh between transverse end pedestals de-fining a load berth on a vehicle running on a way or track past the loader with a change in elevation therebetween to transfer a load thereto or from according to the direction of movement. The way can curve to an arc centered at the pivot as it passes to hold alignment as the forks are lifted or lowered or as the vehicle  is lifted or lowered relatively in transversing this arc on the way past the loader, or the way can be straight and the load support arms have cradles or dolly mountable on the fork to turn when fingers thereon en-gage the side of the vehicle to align with the vehicle for transfer.  The vehicle can have side couplers which engage behind the forward fork arm on its inner curve to gradually accelerate the loader into alignment for transfer or the loader can be started to mesh its fork between the pedestals.          After transfer the loader is pushed away from the car  by the side coupler or the loader pushes the vehicle and turns out therefrom.  The loader can transfer between a transport vehicle such as a railway train and storage dollies.  Dollies preferably transfer with the loader tangentially so the loader can run nonstop in a circle to load or unload a train selectively nonstop.  Wheels supporting the loader can be on legs that swing in a  vertical plane through the pivot axis.      These wheels are grooved to follow a circular track concentric about the pivot and can be switched between concentric tracks having reverse slopes to transfer to or from the vehicle in either direction. The loader can be vehicle mounted or have a stationary pivot and can transfer cargo or passenger con-tainers, dollies,  or pallets for loads such as autos, semitrail-ers, buses of passengers, freight etc.

Abstract: ERROR MONITORING IN DIGITAL    TRANSMISSION SYSTEMS            Abstract Errors in digital transmission are monitored by employing a cyclical-redundancy-check (CRC). In a transmitter, a CRC code word having a predetermined number of bits is generated from a block of bits of a presently transmitted time division multiplexed signal.  The code word bits are then inserted into predetermined bit positions of the next subsequent block of bits of the XTDM signal.  In a receiver, bits of a presently received time division multiplexed signal are compared to bits of a CRC code word generated from the last previously received block of bits to indicate errors in transmission.  In a specific example, a 6-bit CRC code word is employed and the code word bits are inserted into predetermined framing bit positions.

Abstract: ABSTRACT OF THE DISCLOSURE          A process for curing bacon to produce bacon containing no more than 5 ppb of nitrosamines and protected against botulinum growth.  The process utilizes a two-step or two-stage pumping technique.  The first pumping solution is a generally conventional pickle or curing composition except that there has been added a viable culture of a process-surviving bacteria capable of producing an edible acid such as lactic acid.  The second solution contains an edible chemical acidulant for rapidly and effectively lowering the pH of the treated bacon.          The overall effect of the improved process is to provide a cured bacon with markedly reduced nitrite concentrations and also resistant to the development of toxins from botulinum during the storage of the cured bacon.

Abstract: Abstract of the Disclosure:     In an SS (spread spectrum) modem, a high-pass filter (81) for rejecting a low frequency component including an information signal received by demodulation, produces an SS signal component modified by a PN (pseudo noise) code sequence used for the demodulation.          A multiplier (82) substantially regenerates the SS signal component.          Band division may be resorted to, in which case an input filter (161) selects a partial band SS signal for the demodulation.          A transit filter (164) rejects the partial band SS signal.  An SS signal is sent to a destination modem through one of output filters (162) selected for the destination modem.  Each generator (67, 71) may generate a PN code sequence given by a product of PN codes, one having a frame period equal to an integral multiple (unity allowed) of the PN clock period of another.  Each partial band may be about 1/5 of the entire frequency band of the PN code sequence.  A center portion of the band may be used in transmitting a narrow-band synchronizing signal.  In a band division network, the highest partial band may be used for an SS (multiplex) signal and other partial bands, collectively for a baseband TDM signal.     [Fig. 15]
