Abstract: A document sorter for a document dispenser comprises a feeding apparatus for feeding documents to a document feed path, a conveyance apparatus mounted along the document feed path for conveying documents along the document feed path, and a directing apparatus mounted across the document feed path at a 90.degree. angle to the feed path for selectively directing documents along the feed path or for selectively directing documents from the feed path into a selected bin of the document dispenser. The directing apparatus includes a plurality of rotatable selector rotors mounted across the document feed path at a 900.degree. angle to the document feed path, and a D.C. motor for driving each selector rotor in a clockwise direction or a counter-clockwise direction of rotation, as desired.

Abstract: An apparatus for dispensing a specified quantity of bills of a single denomination has a feed mechanism for feeding bills into a first guide path, and a transport mechanism for receiving bills within a second guide path. The first and second guide paths are arranged so that reversal of the transport mechanism causes a single bill to be dispensed from the apparatus via a gap between the two guide paths. If a misfeed is detected, the transport mechanism is maintained in forward operation to collect misfed bills within an internal rejected bill receptacle.

Abstract: An apparatus for counting and verifying documents is provided with a digital control network. The digital control network coordinates the operations of counting and verifying documents. A transport mechanism moves documents along a guide path through the apparatus. Sensors are located along the guide path for determining optical and magnetic characteristics of the documents and producing signals relative thereto. The measured signals are sampled and digitized by an analog-to-digital converter under the control of a microprocessor. Multiple samples of the sensor signals are accumulated within memory as each document passes adjacent to the sensors. The accumulated values are compared with reference values in order to verify each document which passes adjacent to the sensors. Documents are counted after verification. Individual piece counts and monetary values of such piece counts are provided and counterfeit documents, such as passed for United States currency, can be detected.

Abstract: A document size detection device for detecting the size of documents such as non-U.S. currency comprises a housing, a plate mounted in the housing past which each document is moved, and detectors positioned along the plate for sensing the size of each document and for initiating a signal indicating the size of each document.

Abstract: A document imprinting device for imprinting on documents such as checks, and its method of use, comprising a frame, a document feeding mechanism mounted on the frame for sequentially feeding documents, a conveying mechanism for conveying a document from the document feeding mechanism along a document conveyance path, an imprinting mechanism for imprinting the documents conveyed along the document conveyance path, said imprinting mechanism including a print drum mounted on a rotatable shaft having a generally round surface with a flat segment, a sensing mechanism positioned along the document conveyance path for sensing the position of the documents and for triggering the imprinting mechanism such that the document is imprinted at a desired location on the document, and rotation detecting means for detecting whether said shaft makes a rotation.

Abstract: A document delivery and abort mechanism 11 for an automatic document dispensing machine 13 for dispensing currency comprises an accept door 15 for dispensing documents from automatic document dispensing machine 13, a power shaft 17 which operates in response to signals from the automatic document dispensing machine to open the accept door 15 or abort delivery of the currency, an accept door opening mechanism connected between power shaft 17 and accept door 15 for opening accept door 15, a locking mechanism for preventing rotation of the power shaft in a direction that opens the accept door 15 for locking accept door 15 in a closed position, when desired, and an abort door connected to power shaft 17 for aborting delivery of the currency when it has been processed incorrectly.

Abstract: A document dispenser capable of dispensing documents from a plurality of separate bins is constructed of a modular design. The dispenser is constructed by assembling the modules, one for each bin, with each module including an input hopper and a document feeder. The modules are connected together to feed the documents along a common delivery feed path to a stacker which is provided on a module on the dispensing end of the device.

Abstract: A document printer in which a print drum is driven by a direct current electric motor whose voltage is controlled by a first voltage regulator circuit for supplying a first voltage to the motor during a non-printing operating condition and a voltage boost circuit for supplying a higher voltage to the motor during a printing operating condition so that the same document feed rate is maintained throughout the operation of the device.

Abstract: An integrated, microprocessor-based primary control system for a building heating system. The control system includes in one unit a microprocessor and associated circuitry for (1) establishing the high limit of heat exchanger operation, (2) establishing the low-limit of heat exchanger operation for systems having a summer/winter coil, (3) modulating heat exchanger temperature as a function of outdoor temperature, (4) detecting alarm conditions, providing audio-visual signals while locking out heat exchanger operation in response thereto, and (5) providing an override time period for domestic hot water production in systems having a summer/winter coil.

Abstract: A ballistic print hammer assembly which includes a pivotally mounted print hammer driven by an electromagnetic actuator, characterized by low cost and ease of manufacture, high velocity and short dwell time. A rigid pivot upon which the hammer is mounted is simply secured to one side of a frame member. One end of the hammer is disposed in a slot of the armature of the electromagnetic actuator. The stator of the actuator is arranged to be inserted (by means of screw threads) from the other side of the frame member through an aperture so that the armature fits within the actuator stator cavity. An impression control spring is further disposed in a central cavity of the armature to continually produce a biasing force on the hammer which in the free-flight condition of the hammer is a decelerating force.
