Abstract: A universal unit controls the brakes of a truck of a rail vehicle.  The unit includes a service valve, an emergency valve, a variable load relay valve, a release valve, a local control means, a solenoid driver means and a brake assurance means.  The service valve when opened provides a first control pressure.          The emergency valve when opened provides a second control pressure.  In response the control pressures, the variable valve provides to the brake cylinder a load compensated pressure proportional to air spring pressure.  The brakes then apply to the wheels of the truck a force that accounts for the load borne by the rail vehicle.  The release valve when opened prevents the variable valve from providing the load compensated pressure.          The local control means controls the control pressures according to a brake force command signal and a control pressure feedback signal.  The solenoid means operates the valves in response to valve command signals received from the local control means.     The brake assurance means operates in a standby mode in which the local control means controls the release and emergency valves via the solenoid means or in an intervention mode in which  it  does  not thereby  assuring that the  release  and emergency valves open.   This enables the variable valve to provide the brake cylinder with the load compensated pressure and therefore apply the brakes.   The brake assurance means assumes the intervention mode in response to a loss of power or to a predetermined set of conditions.

Abstract: A composite plating apparatus includes a cylindrical electrode which is positioned in a hollow section of a workpiece with a surrounding gap left therebetween. A plurality of through-holes are formed across the thickness of an outer wall of the cylindrical electrode. Composite plating liquid is jetted out through the through-holes and impinge on the inner surface of the hollow section to thereby produce turbulence. The turbulent liquid provides a uniform distribution of ceramic particles in the liquid. As a result, the ceramic particles can be co-deposited uniformly in a metallic matrix, and hence a uniform abrasion-resistant characteristic is obtained all over a resultant composite plating film.

Abstract: A solenoid type magnetic trip assembly for a molded case circuit breaker includes an armature biased against an adjustable stop by a tension spring to set the initial gap for the magnetic trip, so that the spring bias remains constant for the full range of the initial gap. The armature includes an elongated magnetically permeable member mounted by a frame to slide longitudinally along a pair of guide rails. The frame defines a trip surface axially aligned with the elongated magnetically permeable member which engages a trip arm on a trip bar to trip the circuit breaker in response to a predetermined level of overcurrent. A bimetal providing a thermal trip function is cantilevered from a support spaced from the trip bar by the armature, but has a terminal portion at the free end projecting toward the trip bar and through which the elongated magnetically permeable member of the armature extends. A radially enlarged slug on the free end of the elongated magnetically permeable member of the armature is subjected to a magnetic force opposite to the force generated by load current tending to pull the armature into the solenoid coil. This opposing force increases as the initial gap increases, placing the slug closer to the magnetic frame, so that a greater range of trip currents can be selected despite limited room for armature travel,. A gap in the magnetic frame prevents short circuiting the magnetic field where the few turns of a large gauge coil wire produce an unsymmetrical winding. A magnetic shield protects the bimetal from deformation during high current short circuits.

Title: Seed counting apparatus for a planter monitor
Inventor: TEVS NIKOLAI
IPC: G06M1/10
Filed: 1998-05-19
Granted: 2001-09-18
Abstract: A seed counter for counting seeds flowing through a duct includes a light transmitter on one side of the duct and light receiver on the opposed side of the duct together with an electronic circuit effecting analysis of the signals received by the receiver to generate a seed count value which represents accurately as possible the number of seeds passing through the duct. The transmitter and receiver each comprise a channel-shaped body with diodes at a base of the channel with the channel filled with a translucent potting material facing into the duct. The circuit receives the signals which include for each passage of a seed or a clump of seeds a temporary reduction in light intensity which is converted to a reduction in voltage.  Prior to start up the steady state voltage is measured and the current to the transmitter varied to provide a predetermined level of signal at the receiver.  The circuit includes a DC compression circuit and a AC compression circuit at an amplifier so as to provide an output signal in a required amplitude range. An auto-biasing section maintains a steady state signal at a required level. The amplitude of the signal is compared to a threshold by generating a first signal which is offset by the threshold and a second signal which is delayed by a predetermined time period, the comparison generating a square wave output when one of the signals crosses the other signal. The seed counter is used in a monitoring system having a central monitor which can be operated to vary the parameters of the comparison circuit including the time delay. The use of the comparison circuit assists in determining the difference between a single seed and a clump of seeds passing the transmitter/receiver simultaneously.

Abstract: The back end position of a pulse, which is transmitted from a remote control, varies according to the transmission distance, and the pulse width changes. A remote control receiver of the present invention detects the pulse width of a header, which is formed at the head of each frame in a remote control signal from the remote control, so as to detect the transmission distance of the remote control signal and a change in back end position of each pulse in a data part, which is transmitted after the header. Then, the back end position of each pulse is corrected to original.      This eliminates the change in pulse width resulting from a change in transmission distance, and increases the allowable range of the transmission distance of the remote control.

Abstract: La présente invention concerne un procédé et un appareil de compression de données à affectation adaptative des bits et codage hybride à entropie sans perte. Le système considéré et constitué de trois composantes: (1) une phase de transformation, (2) une phase de quantification, et (3) une phase de codage à entropie sans perte. La phase de transformation (1) utilise un algorithme de transformation à vaguelettes. La phase de quantification (2) fait une estimation adaptative des valeurs des paramètres définissant une approximation entre la dimension de quantification et le logarithme de l'erreur de quantification, et calcule par récursivité la dimension optimale de quantification applicable à chaque bande pour obtenir le débit binaire attendu. Le procédé consiste à transformer la bande de base et ses sous-bandes en matrices de quantification par utilisation de dimensions de quantification correspondantes. La phase de codage à entropie sans perte (3) part de la constatation que les caractéristiques d'entropie des longueurs d'exécution des valeurs d'indices nuls dans les matrices de quantification de sous-bandes sont différentes des caractéristiques d'entropie concernant les indices non nuls. Chaque matrice de quantification est soumise à une discrimination servant à extraire chaque indice non nul et à le mettre dans un flux séparé, et le reste des informations de position est soumis à une discrimination entre flux à longueurs d'exécution de valeurs paires pour les "0", et flux à longueurs d'exécution de valeurs impaires pour les "1", ces trois flux subissant séparément un codage Huffmann réalisé de façon conventionnelle.
