Abstract: A plate-link chain for a belt-driven conical-pulley transmission. The chain has a large number of link plates that are articulatingly connected with each other by rocker members, which link plates are positioned one behind the other and are offset from each other transversely relative to the longitudinal direction of the plate-link chain, and also partially overlap each other. The chain has a plurality of link plates of two different lengths in the longitudinal direction of the chain, with openings to receive the rocker members. The arrangement of the link plates in the longitudinal direction of the chain is such that a long link plate is followed by a short link plate.

Abstract: A continuously variable power-branched transmission for a motor vehicle, including an input shaft, a variable speed drive unit having pairs of conical disks and a continuously variable transmission ratio, a gear system, and an output shaft. Two control clutches connect the variable speed drive unit and the gear system so that when going through the entire transmission ratio range of the power-branched transmission the adjustment range of the variable speed drive unit is passed through a plurality of times. The transmission also includes rotational speed sensors and a controller that determines whether a change in rotational speed is triggered by a change in the transmission ratio, and when it is not triggered by a change in the transmission ratio, the controller adjusts the variable speed drive unit so that the change in rotational speed not triggered by a change in the transmission ratio is compensated.

Abstract: A torque transmitting device in a drive train of a motor vehicle to transmit torque between an internal combustion engine having a drive shaft and a transmission having coaxial input shafts.

The material is held in the preheating stage long enough to obtain at least some degree of oxidation on the surface of the material, and the material is heated further in a following, final heating stage by burners situated in a furnace and that are supplied with a fuel and an oxidizing gas.

Abstract: A shipping container for shipping diagnostic specimens. An outer container includes inner foam panels that define an inner cavity enclosed by a closed cell polymeric foam for receiving items to be shipped. The inner cavity has an H-shaped transverse cross section for receiving specimen vials that can be packaged in a polymeric bag having several side-by-side compartments for receiving specimen vials. A freezable material is placed within the inner cavity and adjacent to the specimens to maintain the specimens packed within the container below a predetermined temperature during shipment. The foam defining the inner cavity provides insulation to aid in maintaining the temperature of the contents.

Abstract: A method for igniting a fuel/oxidant mixture in an industrial furnace. At least one fuel supply conduit and at least one oxidant supply conduit is provided, each conduit having an opening that opens on a side of the burner head that faces the furnace interior space. Fuel and oxidant are supplied to the burner head, and a light detector for detecting ultraviolet light, or other light wavelengths, is provided for detecting light that indicates the presence of a flame. A laser is positioned to emit a laser beam onto a point on the burner head adjacent the conduit outlets and to heat that point to a temperature exceeding the ignition temperature of the fuel/oxidant mixture. When the burner has ignited, the detector emits a signal to a control circuit that extinguishes the laser beam.

Abstract: The input rotational speed of a belt-driven conical-pulley transmission is determined by measuring a wheel rotational speed and the transmission ratio and by calculating the input rotational speed therefrom. In order to ascertain the slipping of a CVT transmission, the rate of change in the transmission ratio is drawn upon, or an acoustic parameter of the transmission is used. In the fluid control system, a valve is used whose opening cross-section is controlled according to the one differential pressure. In order to oil the conical discs, injection holes of an injection tube are used that passes through a slot provided in a slide rail resting against a strand of a flexible torque transmitting member of a conical disc flexible drive.

Abstract: A method and apparatus relating to the combustion of a fuel with an oxidant in a heating furnace, wherein the fuel and the oxidant are delivered to a burner head. In a first method step fuel and oxidant are emitted from the burner head in close proximity to each other, so that combustion essentially takes place close to and at a small distance outward of the burner head, and until a temperature is reached in the furnace space that exceeds the spontaneous combustion temperature of the fuel. In a second method step the fuel and the oxidant are instead emitted from the burner head at a mutual distance apart, so that combustion takes place at a distance from the burner head corresponding to at least the diameter of the burner head and outward of the burner head.

Abstract: A method of achieving co-acting services in a data system that includes telephone or data services and at least two computer systems. A transaction database connected to each computer contains transactions that are identified by transaction references, where each transaction is part of a data program for executing a service. Fetching of transactions for execution in the data system is initiated in response to an incoming call from a telephone or from an external computer. The call includes an identification of the caller and type of call. All instructions from one computer system to another takes place through the agency of the transactions, wherein certain transaction references identify transactions that upon execution transfer the service to a computer system other than the call-receiving computer system for execution. Caller information is transferred together with the transfer of the service.

Abstract: A pressure limiting valve having a spool with raised spool lands. The spool is slidably received in a spool bore having inflow and outflow grooves that form control edges. The valve has two control edges, and a hydraulic resistance is connected in series with one of the control edges. Increasing static pressure losses at the control edges during flow, so-called flow forces, can be offset by an increasing back pressure on the valve spool, which is produced by the hydraulic resistance.
