Books (magazines) are compiled from signatures demographically in that persons in the same mailing zone may receive books with signatures of different content. The books are trimmed while superimposed one on another, but nonetheless proper mailing sequence (zone separation) is maintained by shifting a trailing book forward to lie atop the next leading book just before trimming, and then the shifted book is returned to its former position before being mailed thereby to preserve the mailing zone s...

Signature machine for printing an inside page of a signature as it moves through the machine from a signature supply source to the signature gatherer, made possible by positioning an ink jet printer in a raceway between the supply source and the gatherer. After being printed the signature is folded to bring the inside pages into juxtaposition before being delivered to the gatherer. There may be two supply sources for different signatures, feeding different signatures to be printed differently be...

Digital signal processing apparatus which can be tested by signature analysis is arranged so that a predetermined number of its ROM locations have stored therein pre-selected values whereby the signature analysis is independent of the contents of the remainder of the memory location. Appropriately valued bytes are stored in the N last-record memory location and these bytes establish a predetermined signature for each data pin regardless of firmware changes.

A signature feeding machine, in which signatures are transferred one by one from a stack in a supply station, is so constructed as to enable the signatures to be separated automatically.

A caliper system for a cyclically operable signature gathering machine in which each unbound book of signatures is probed with a beta particle beam or other beam and the energy level of the emergent beam is compared with a reference to control machine operation and prevent binding of incorrectly assembled books.

Improved operation of a cyclically operable signature gathering machine is achieved by latching the gripper, which feeds a signature from a hopper, against the signature pile in response to a command signal that signatures are not to be fed from the hopper.

An apparatus for registering a signature moving along a surface, such as a drum, includes one or more pinch rollers for advancing the signature, and a register stop for stopping the advancement of the signature. The register stop is rotatable about an axis so as to accommodate skewing of the signature. The pinch rollers do not rotate with the register stop, but remained aligned with the drum.

In a process for ensuring the data integrity of software for influencing operation of a control unit of a motor vehicle, a pair of keys is provided for encrypting and decrypting electronic data. The first key is stored for access by a control unit in the motor vehicle, and software which is to be imported is signed by means of the second key. The signed software is imported into the memory of the control unit and the signature of the software is checked by means of the first key. The signature i...

The present invention provides methods and compositions for use in rapid test or prediction of the propensity of a test compound to induce cholestasis in a subject. The invention also includes a Cholestasis signature database as well as the method of deriving such database.

A signature feeder with a stack-supporting conveyor for moving a stack of signatures to a dispensing location. A pick-up conveyor engages the stack and positions the signatures in an imbricated stream and a guide member directs them to a deposit location where the signatures are again placed into a stack from whence they are dispensed to a feeder mechanism. Sensors are disposed at the forward face of the stack and also at the deposit location, and the sensors are connected to electric motors whi...
