Abstract: An adaptive-predictive control system and method for controlling single-input, single-output or multivariable time- variant processes with known or unknown parameters and with or without time delay, is disclosed. The adaptive-predictive control system of the present invention uses an adaptive-predictive model to determine what control vector should be applied to the process being controlled to cause the process output to be at some desired value at a future time instant. The parameters of the adaptive-predictive model are updated on a real time basis in a manner which will cause the output vector predicted by the model to be equal to the actual process output vector.

Abstract: A driving circuit for a four phases (1, 2, 3, 4) step motor, where each stable rotor position is reached by suitably energizing the series of two of the four phases, comprises a circuit (22) which controls the current in the energized phases by comparing a current related signal with a reference signal. 
     Particularly, such circuit disconnects the series of two phases from the power supply and ground when the energization current reaches a predetermined upper threshold value and connect it again to the power supply and ground when the energization current, which is maintained in the phases through recycle diodes (9, 10, 11, 12), falls below a predetermined lower threshold value. 
     In such way the energization current within the phases is kept nearly constant and this reduces to a minimum the winding copper losses, under the same mechanical performances. 
     The cross configuration of the windings, with a current sensor (19) in the center of the cross, further enables to reduce to a minimum number the components of the control circuits.

Abstract: A read only memory is provided in which the memory cells (24) are single metal gate or silicon gate field effect transistors (26). Each FET (26) has one of several different thresholds or states. The size or area of the FET gates (64) at the surface of the semiconductor chip are substantially the same regardless of the cells threshold or state. The input to the gates is a ramp, and the cells are rendered conducting by the amplitude of the ramp at a given instance. The output of a cell is fed to several flip-flops (42,44,46), which are synchronized with the input ramp, thereby setting the flip-flops in accordance with the threshold or state of the cell. An encoder (48) converts the output from the flip-flops to a bit binary signal. This permits a very high density ROM, e.g. 128k on a single chip.

Abstract: When a track of a disk memory is read into a cache memory, starting from the instant at which the read for caching is determined, a table (60) of emulated track positions is set up recording the track positions of successive records. When an error or other event makes it necessary for the host computer to revert from the cache memory to the disk memory, reorientation of the addressing is effected by selecting the emulated track position from the table (60) for the record preceding that required. A divider (64) divides by bytes per sector to derive an equivalent sector value which is compared by a comparator (66) with the actual sector signal to enable (71) reading a predetermined number of bytes from the disk to the computer. Enabling is delayed (67) by the byte remainder from the division (64).

Abstract: An improved signature handling apparatus includes a plurality of signature feeders which are operatable to form groups of signatures on a conveyor. Detectors are associated with the signature feeders to detect a signature misfeed and a resulting defective group of signatures. The conveyor sequentially transports the groups of signatures to a delivery assembly which directs groups of signatures containing a predetermined number of signatures to a trimmer. The delivery assembly directs defective groups of signatures containing less than the predetermined number of signatures to a reject tray. The delivery assembly includes a nip through which the signatures are fed from the conveyor. The size of the nip can be varied by varying the distance between rollers disposed on opposite sides of the nip. A control assembly decreases the distance between the centers of rotation of the rollers to decrease the size of the nip when a group of signatures, containing less than the predetermined number of signatures, is to be fed through the nip.
