Abstract: Abstract A unique cheese results from combining milled curds typical of cheddar cheese and stirred curds typical of a soft cheese, such as mozzarella. The curds from two cheese vats are combined by pumping a liquid mixture of the stirred curd and whey over a drained loose mass of milled curds. The consolidated curds are then stirred together and salted to simultaneously terminate their fermentation processes. The blended curd mass is molded, pressed and aged similar to cheddar cheese. The resulting cheese has a unique flavor, resembling that of cheddar cheese, and a unique consistency, resembling that of its stirred curd cheese component. A specific example is a mixture containing discrete zones of 60% whole milk cheddar cheese and 40% part skim mozzarella cheese, by volume.

Abstract: DATA PROCESSING SYSTEM WITH CPU REGISTER TO REGISTER DATA TRANSFERS OVERLAPPED WITH DATA TRANSFER TO AND FROM MAIN STORAGE                 Abstract The present invention is directed to a conven-tional data processing system having a CPU and at least one external unit such as the main storage unit acquiring data from or providing data to the CPU and I/O bus for the transfer of data between the CPU and the external unit.  The apparatus of the present invention provides for transfers to and from this external unit, e.g., main storage being overlapped with a register to register data transfer routinely carried out in the CPU to implement various CPU operations and computation functions.  The CPU in-cludes apparatus for transferring data to or from said external unit over the I/O bus during syn-chronized time cycles.  The CPU also includes local storage apparatus which comprise a plurality of registers as well as expedients for transferring data from register to register.  Control apparatus con-trols the register to register data transfer so that such transfers are conducted during time cycles coincident with the transfer of data to or from the external storage unit.  Thus, the register to regis-ter data transfers within the CPU are overlapped with the data transfers over the I/O bus to main storage. The data transfers to and from main storage are generally considerably longer that the simpler register to register data transfer.  The apparatus may be operated so that several register to register transfers may take place during the time required for a transfer of data to or from the external storage unit.  The present invention further includes means for dynamically determining data dependencies between the register to register transfers and the I/O bus transfers.

Abstract: ABSTRACT OF THE DISCLOSURE            A filter wall constructed separately from the frame member  is  clamped in a clamping slot,  to which toward the outside edge of the filter plate a widened sealing slot in a shoulder of the support is connected.  A projecting edge of the filter wall extends into the latter slot with the shoulder overlapping, the filter wall having an annular flange directed to the outside.  The seal is arranged in the sealing slot and has a U-shaped cross section with  two  arms  extending  inwardly,  whose arms enclose and seal both sides of the annular flange and which seals the support on one side and the frame member on the other side.  The spacing between the seal and the joint  is sufficient that upon  release of the closing pressure of the filter press, without disengaging it, the frame member  can be moved sufficiently far from the support that the pressurizable chamber is unsealed at the seal in the sealing slot.

Abstract: Abstract of the Disclosure:     In a predictive encoder for use particularly in a conference television system, a signal processing unit is used in producing a prediction signal and comprises three prediction circuits (22, 23, 31) and a selection circuit (24) coupled to the prediction circuits.  The prediction circuits are for prodicing an inframe, an interframe, and a background prediction signals, respec-tively.  Those signals are produced by processing an original signal at instants which precede a current instant and are different from one another.  The selection circuit is for selecting one of the inframe, the inter-frame, and the background prediction signals.  Therefore, it is possible to produce the prediction signal suitably predictive of the original signal.  The signal processing circuit serves equally well in a predictive decoder.
