The position of a pen or stylus with respect to a piece of paper is converted into two DC signals in a pair of potentiometers which are mechanically linked to the pen support mechanism. The DC signals are then converted into AC signals which are recorded on magnetic tape. When the tape is played back, the AC signals are reconverted into DC voltages which drive a negative feedback servomechanism system and thereby reproduce a signature previously recorded on the magnetic tape.

Signatures moving in a substantially continuous stream and arranged in overlapping fashion, folded edge forward, pass beneath the counter to activate a signature intercepter mounted with a self-cleaning housing. The intercepter, in turn, drives a cam which activates a cam follower each time a signature passes beneath the intercepter. The cam follower moves an interrupter blade whose positioning alters the magnetic field of a magnet means to control the operation of a switch means providing a swi...

A signature formed as a plurality of layers of paper sheets and having a fold line is provided along the fold line with a line of spaced perforations. This line of perforations is formed by a signature perforating knife which has a plurality of spaced perforating teeth. The folded signature avoids creases and bulges during stacking of plural signatures.

A case formed with a compartment having a forwardly facing opening therein and including cartridge mounting means. A ribbon cartridge is received within such compartment and is formed with a check-receiving slot. Rollers are carried on the carriage for mounting an ink ribbon arranged with its ink surface facing such slot. A base plate is mounted in such compartment under the ink ribbon and a floating signature bar is disposed over such ribbon. The signature bar is normally biased upwardly out of...

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.

A signature inserter for a signature gathering machine having two hoppers, arranged one above the other; two rotary extractor drums, each of which is associated with one hopper and provided with means for extracting individual signatures from that hopper; a rotary transfer drum for transferring individual signatures from one extractor drum to the conveyor and a rotary intermediate drum for transferring signatures from the other extractor drum to the first extractor drum. Finally, the signature i...

Signature feeding machine operable in a run mode or jog mode and having means to time differently the application and disapplication of vacuum to an extractor in accordance with the modes.

A stacker having platforms movable along a path by chains. Cam followers on the platforms engage a cam surface which controls the platform path. The chains are driven by a motor in a closed-loop system which monitors the platforms and controls their speed. The closed-loop system first decelerates the platforms and thereafter stops one platform in the intercept-ready position. The platform cam follower enters a claw which moves the end of the platform through the stream to collect signatures when...

Systems and methods for protecting transaction information stored in a database of a gaming network. To accomplish this, a transaction signature is generated each time the user completes a transaction on a gaming machine. The transaction signature is generated using transaction information from a particular transaction. The transaction signature and transaction information are stored together in a network database. Upon subsequent access to the transaction information in the database, the transa...

A signature stream is intercepted by a bucket unlatched from the intercept position. The buckets are moved by drive chains. A spring assembly maintains tension upon the drive chains and spring loads the bucket in the "home" position, providing a detent action upon this bucket to accelerate the bucket and also provide a force for drop-out of the bucket. A bucket cam follower guides the bucket to move from a normal path to the "home" position. A microprocessor selectively halts each bucket during ...
