  • Patent number: 6124807
    Abstract: Process for regulating traffic by means of moveable light signalling equipment (mobile traffic lights; A, B), particularly at restricted areas (E), using sensor controls which prescribe go times (green phases, T.sub.F) and clearance times (red phases T.sub.R) in the area to be secured, i.e. along a blocked stretch (S), wherein the transit time (T.sub.D) of vehicles (F) over a measured distance (M) extending substantially along the blocked stretch (S) is measured and the clearance time (T.sub.R) is established as a function of the transit time measurements (T.sub.D) obtained.

  • Patent number: 6121009
    Abstract: A small diameter flexible electrode designed for subcutaneous in vivo amperometric monitoring of glucose is described. The electrode is designed to allow "one-point" in vivo calibration, i.e., to have zero output current at zero glucose concentration, even in the presence of other electroreactive species of serum or blood. The electrode is preferably three or four-layered, with the layers serially deposited within a recess upon the tip of a polyamide insulated gold wire. A first glucose concentration-to-current transducing layer is overcoated with an electrically insulating and glucose flux limiting layer (second layer) on which, optionally, an immobilized interference-eliminating horseradish peroxidase based film is deposited (third layer). An outer (fourth) layer is biocompatible.

  • Patent number: 6122320
    Abstract: The circuit for motion estimation in digitised video sequence encoders comprises at least an integrated circuit component (IM, IM1 . . . IMn) which is arranged to perform either the function of determining motion vectors and associated costs for different prediction modes, or the function of vector refinement, possibly in addition to prediction mode selection. The circuit (IM) is based on the use of two operating units (M1, M2) which are arranged to concurrently process in different ways different pixel groups according to a MIMD technique. Preferably, when the circuit performs motion vector determination, the operating units (M1, M2) are programmed to execute a genetic algorithm exploiting an initial vector population taking into account the temporal and spatial correlations in the picture.

  • Patent number: 6121337
    Abstract: An improved closed cell polymer foam and foaming agent involving the use of a hydrogen-containing halocarbon blowing agent (e.g., HCFC-22) in combination with an effective amount of a hydrogen bond forming blocking agent (e.g., organic ether, ester or ketone). The presence of the blocking agent is shown to significantly reduce the escape of blowing agent from and entry of air into the foam resulting in low thermal conductivity over a longer period of time and improved thermal insulation value. The present invention further relates to compositions comprising a blowing agent and an active hydrogen-containing compound, commonly referred to in the art as B-side compositions or blends, and using such compositions for producing polyurethane and polyisocyanurate foams in which the blowing agent comprises a major proportion of 1,1,2,2-tetrafluoroethane (HFC-134).

  • Patent number: 6119961
    Abstract: In an asphalt distributor having a tank for holding asphalt and a pump for pumping asphalt from the tank to a spraybar, a self draining asphalt strainer is provided. The asphalt strainer includes a body having an inlet and outlet with a filtering chamber disposed between the inlet and the outlet. A filter or straining element is disposed in the filtering chamber for filtering asphalt flowing between the inlet and the outlet. A conduit extends the inlet into the filtering chamber. A pair of valves are disposed on each end of the conduit forming a suckback chamber therebetween. A suckback tube is connected to the conduit intermediate the valves and extends into the filtering chamber. The pump is bidirectional and has a reverse mode which forces asphalt back through the outlet and inlet into the tank. The strainer has a first flow passage from the outlet to the inlet through both of the valves when open.

  • Patent number: 6121824
    Abstract: A subcircuit including three bipolar transistors is substituted in place of a single bipolar transistor to achieve extrinsic base and emitter series resistance compensation in translinear circuits. The subcircuit substitution is applied to a Brokaw-type bandgap cell. The subcircuit substitution is applied to a current multiplier circuit, and the resulting circuit is rearranged for external control circuit efficiency. A low-voltage bandgap circuit uses an operational amplifier feedback circuit with bipolar transistors having differing emitter areas and a voltage divider to generate base voltages for a Brokaw-type bandgap cell. A proportional-to-absolute-temperature sensor circuit uses parallel two stacked bipolar transistor paths in which the bipolar transistors' emitter areas are selected to adhere to a relationship so as to provide extrinsic series base and emitter resistance compensation.

  • Patent number: 6115983
    Abstract: A block assembly and wall system wherein a block of masonry, or other material is provided with a vertical through opening having an enlarged and offset lower portion and a smaller upper portion. An interlock element has an enlarged offset upper portion and a smaller lower portion to provide for insertion of the latter into the upper portion of a block opening. The upper portion of the element is entered into the lower portion of an adjacent block placed atop the first block. The blocks are thus secured in position horizontally and, alternatively, the blocks may be secured vertically or in a "battered" wall construction. That is, with the connecting elements in a first attitude, a conventional vertical wall is provided whereas a 180.degree. (one hundred eighty degrees) rotation of the elements about their vertical axis results in a "battered" wall.

  • Patent number: 6116530
    Abstract: A jaw crusher for crushing rocks combines a hydraulic adjustment of the bite with an air spring tensioning arrangement which maintains a desired tensile force even with variation of the bite. The air spring arrangement is reliable in the dirty environment and also has long life. The use of several air springs in combination with a pressure sensing arrangement adds a safety factor. The more consistent tensioning force allows adjustment of both the tensioning arrangement and the bite of the rock crusher during operation thereof.
