Abstract: AUTOMATIC FRAMING IN TIME DIVISION MULTIPLEXER    Abstract A method and apparatus are described for automatically generating the frame that is used in a bit-interleaved time division multiplexer (TDM).  The apparatus comprises a microprocessor, two random access memories in which are stored the channel select signals, means for determining the transmission frequencies of each channel and a computer program which is stored in the memory of the computer for calculating the distribution of the channel select signals in the frame.  With such a system, the frame can be reconfigured in about thirty seconds.           Two random access memories are preferably used for the storage of the channel select signals.  While the signals stored in one memory are being used to generate the actual frame, a new set of channel select signals can be stored in the other memory.  After such an updated frame is written in the second memory, the task of generating the channel select signals can be switched from the first memory to the second memory without loss of any data from any of the data channels.

Abstract: ABSTRACT OF THE DISCLOSURE        Human monoclonal antibody reagents for specific therapeutic and diagnostic use against such diseases as hepatitis, rabies and tetanus can be prepared from human peripheral blood lymphocytes especially selected for their capability to bind to a selected antigen. The selected lymphocytes are infected with Epstein Barr Virus and after culture are cloned by limiting dilution on irradiated feeder layers of autologous human mononuclear cells in the presence of T cell growth factor.  Clones producing the antibody to the selected antigen are recovered and grown in bulk culture and the desired reagent prepared therefrom.          Clones thus produced may be fused with thioguanine-resistant ouabain-resistant human myeloma cell lines so as to produce a hybridoma which is more stable, which has a higher cloning efficiency, and which produces more antibody.

Abstract: Abstract of the Disclosure Photographic assemblages, elements, receiv-ing elements and cover sheets comprise a combination of two timing layers and a neutralizing layer for use with negative-working silver halide emulsions and positive-working redox dye-releasers.  The outermost timing layer has a negative temperature coefficient and has a development accelerator associated there-with to increase the development of the silver halide emulsion at low temperatures.  The timing layer next to the neutralizing layer has a greater penetration time by the alkaline processing composition as that the neutralizing layer is permeated only after silver halide development has been substantially completed. The temperature latitude of the system is thereby increased.

Abstract: COMBINE SPEED CONTROL                   ABSTRACT OF THE DISCLOSURE A ground speed control for an agricultural combine driven by a turbocharged engine through a variable transmission continuously monitors a plurality of speed and load parameters of the combine and engine, identifies the controlling parameter representing the limiting capacity in the harvesting process as field conditions change, and varies combine ground speed in response to such controlling parameter to maximize the harvest cutting rate.  Sensors monitor ground speed, boost pressure and engine speed parameters and convert them to electrical signals which are compared to boost pressure and ground speed setpoint signals selected by the operator and to a fixed engine speed setpoint signal to derive error signals for such parameters.  Voltage level sensitive OR-means and AND means establish deadbands for the error signals having upper and lower limits on opposite sides of the corresponding setpoint signals.  The OR-means generates a speed decrease signal to decrease the transmission drive ratio and slow down the combine when any positive error signal is beyond its upper deadband limit.  The AND-means generates a speed increase signal to increase the transmission drive ratio when both boost pressure and ground speed negative error signals are beyond their lower deadband limits.  The speed increase and speed decrease signals are modulated by a rate of response signal which is a function of the magnitude of the parameter error signals so that the control both identifies and responds to the controlling parameter which has the greatest error and also responds at a rate which is a function of the magnitude of such error.
