Abstract: CONTROL FOR AN ELECTRICAL GENERATING        AND DISTRIBUTION SYSTEM, AND METHOD OF OPERATION                Abstract of the Disclosure A control for an electrical generating and distribution system utilizing a plurality of interconnected microprocessors.  An electrical system, for an aircraft for example, may have two engine driven generators and an auxiliary power unit generator with loads connected to each of the engine driven generators through generator circuit breakers.  An electrical distribution bus connected through bus tie breakers interconnects the load circuits and the auxiliary generator so that any one generator can power either or both loads.  Each generator has a microprocessor generator control unit responsive to the associated generator conditions to control generator operation.  A microprocessor bus power control unit is responsive to distribution circuit conditions and correlates information from the generator control units, contributing to operation of the bus tie breakers, controlling distribution of power from the generators to the loads.  Serial data links between the bus power control unit and each of the generator control units provides for communication of input and control information and enables comparison of redundant circuit information enhancing reliability of the system operation. A generator voltage regulator utilizes the microprocessor of the generator control unit to develop an error voltage which is added to the average phase voltage of the generator, controlling the generator field current.  In the event of a phase failure the generator control unit senses an abnormally high phase voltage condition, disables the average phase voltage circuit and the regulator continues to operate with the error voltage.

Abstract: A B S T R A C T    A circuit for supplying controlled direct current power to an electric discharge vapor lamp during ignition, warm-up and normal operation.  A bridge rectifier and a capacitor voltage doubler convert standard alternating current line voltage into a direct current voltage of adequate magnitude  to operate the lamp.  The lamp is connected in series with a semiconductor control circuit across the DC supply.  The semiconductor control circuit operates as a resistive ballast whose effective resistance decreases as vapor pressure within the lamp increases during warm-up, thereby limiting lamp current to a safe value immediately after ignition while reducing the amount of power dissipated in the ballast cir-cuit during normal operation for improved efficiency.  The conductivity of the resistive ballast circuit is controlled in response to variations in both lamp voltage and lamp current to control the amount of power delivered to the lamp.  In a second embodiment, controlled rectifiers in the bridge maintain a constant voltage drop across the semiconductor ballast circuit and a self-oscillating source of firing pulses is employed to start the lamp.

Abstract: An automatic money handling device for receiving bills and coins for dispensing bills and coins as change. The device has a storage reel, first and second bill belts extending from a first and supply reels around a first and second entrance rollers at an opening to the housing then to the storage reel. The two belts converge at the entrance rollers and then extend in superposed relation from the entrance rollers to the supply reel. Reversible drives can cause the belts to travel toward and away from the opening for receiving, dispensing and storing bills. A first sensor outside the opening senses the presence of a bill and can control the operation of the drive motors. A second sensor inside the housing adjacent the entrance rollers senses if and when the bill has been drawn far enough into webs and belts operation of the forward drive, thus positioning a tendered bill at a viewing station for inspection. The second sensor is an optical sensor for causing any bill not having a predetermined opacity to be rejected. A time delay is provided for halting forward drive of the belts if a bill tendered does not reach the second sensor within the preset time period.

Abstract: ABSTRACT:       An integrated circuit comprising a plurality of adjustable voltage-current converters, of which one con-verter is employed as a reference converter.  The refer-ence converter is included in a control loop.  To the input of the reference converter an input voltage is applied in that a first current is passed through a refer-ence resistor connected to said input.  A second current, which is in a fixed ratio to said first current, is com-pared with the output current of the reference converter and this reference converter is then biassed so that its output current corresponds to said second current.  In this way the transconductance of the reference converter is determined by the reference resistor and the ratio of the first and the second current, so that this transcon-ductance is highly independent of process, temperature and supply-voltage variations.  The other converters are biassed by signals derived from the bias signals for the reference converter and thus have corresponding transcon-ductances.

Abstract: Abstract of the Disclosure A semiconductor assembly comprising a flat disc-shaped semiconductor with terminals on opposite faces with an electrically conductive heat sink in electrical and thermal contact with each face.  The semiconductor device and heat sinks are enclosed and maintained under compression by a rigid frame.  The heat sinks are electrically insulated from each other and from the rigid frame by an insulating bond which secures these components together.  Variations in compressive pressure holding the heat sinks in facing contact with the semiconductor device is compensated by a thermally responsive element positioned between each heat sink and the rigid frame in linear alignment with each other and the semiconductor device, whereby increases in temperature will expand the thermally responsive element to increase compression forces on the assembly of heat sinks and semiconductor devices.

Abstract: NON-COUNTERFEITABLE DOCUMENT SYSTEM                 Abstract of the Disclosure A system is disclosed for authenticating an object on the basis of certain physical phenomena or character, specifically, measurable, but not practicably duplicable random variations in the object.  In one form, the object (authenticator (T)) is a paper tag having a reference space (14), the varying translucency pattern of which is a measurable but practicably unduplicable characteristic of the paper.  The reference space (14) is sensed to provide reference signals indicative of the varying translucency.  A reference numeral (10) is then provided from some registered form, as on the tag or in a list.  If the numeral (10) is readily accessible, it likely will be cryptographically encoded.  Note the value of putting encoded information on the tag to avoid the need for large reference files.          For verification, freshly sensed reference signals, as from the tag (T) (actually characteristic of the tag) are compared with signals that previously were sensed as characteristic of the tag (T).  Structures are disclosed as specific forms of the authenticator (T), along with apparatus for authenticator production, detection and manipulation.  Different forms of tags (210) are disclosed, the measurable characteristic of which involves light transmissivity and reflectivity. Apparatus (111) for spectrographic confirmation of tag material is also disclosed.  In an illustrative form of a tag (T) as an identification means, tags and processing apparatus utilize magnetic medium (218) and printed images (214).  The magnetic medium is also disclosed to be recorded as for developing information on shelf life and sales channels.

Abstract: ABSTRACT OF THE DISCLOSURE   Electrical equipment has its components mounted on a plurality of circuit cards.   The communication to and from the cards, the supply of supply voltages, etc., take place via conductors arranged on a connection device.  The circuit cards are connected to the conductors by means of contact devices.  At least some of the conductors are interrupted at each contact device on the connection device.  Some of the cards, are slave cards, and are provided with means for bridging the interruptions, whereas others, the main cards, have no such bridging means.  By plugging an optional number of slave cards into the connection device immediately adjacent to a main card, a functional unit is formed at an arbitrary location on the connection device.  The conductors provided with interruptions form a local bus for internal communication within a multi-card functional unit.
