Abstract: Abstract of the Disclosure An enclosed finishing vat for cheese making.  The vat has a generally oval configuration and an agitating unit is mounted for reciprocating movement on a frame above the vat and includes a vertical drive shaft that extends through a slot in the top of the vat. The lower end of the drive shaft carries a rotatable support arm and at each end of the arm both a stirring paddle and an unloading paddle are pivotally mounted.          The stirring paddle and unloading paddle extend in opposite directions from the respective end of the arm.  In operation, the agitating unit reciprocates along the length of the vat, and the arm is rotated such that the stirring paddles lead in the direction of rotation and stir the curd, while the unloading paddles trail and float on the curd.  To unload the curd from the vat, a discharge opening in the bottom of the vat is opened and the direction of rotation of the arm is reversed, whereby the unloading paddles lead in the direction of rotation and scrape along the bottom of the vat and deliver the curd through the discharge opening.

Abstract: Abstract Expandable memory system having add-on modules beginning at fixed address boundaries, e.g., 2K (K=1024), and having verification and authorization features.  A non-volatile memory stores a bit corresponding to each 2K memory boundary.  When an add-on program is authorized at a par-ticular boundary address, the corresponding bit is set. The base program checks each bit and, if it is set, reads the first location of the corresponding add-on program.  If the data read from the new module matches some reference, e.g., the boundary address itself, then program control branches to the add-on program.  Additional verification features include cyclic redundancy checks of the added code. Alternative operation includes branching to a verified add-on program that tests its own authorization bit which, if reset, causes a branch to the next verified add-on program, and so on.

Abstract: F. W. Lin 3-1 DIGITAL SERVO SYSTEM        A digital servo system adapted for use in a dual mode coarse-fine servo system to control a movable member from a starting position to an at rest destination position.  The digital servo generates a pulse train in response to varying space phase cyclic analog position signal A from an encoder coupled to the movable member.  Each cycle of an analog posi-tion signal represents a small incremental amount of movement by the movable member.  The pulse train provides a change in its state in time with the varying position signals.  In the pre-ferred embodiment, eight changes occur per cycle.  The pulse train is integrated to provide a velocity signal which is compared with a command velocity signal.            REP:llf

Abstract: ABSTRACT OF THE DISCLOSURE Circuitry for automatically and dynamically reconfig-uring the channel or port configuration of a modem handling a plurality of ports.  A standard signal such as DTR (data terminal ready) is used to provide a code to a master modem indicating the particular port configuration requested by cooperating apparatus. The requested configuration code is continuously compared to a code stored by a shift register controlling the actual modem port configuration.  When the requested code changes, an indication of the code change is transmitted to a communicating slave modem and a control signal is sent, after a suitable delay, to the shift register to conform its contents to the newly requested configura-tion code.  During the delay, the slave modem switches to the newly requested configuration.  The circuitry follows a defined sequence of configuration switching, dropping channels successively and adding channels by passing through the state where all channels are active.  In an  alternative system operation, each of two communicating modems may be synchronized by the cooperating appara-tus such that a configuration charge need not be communicated across the transmission line.
