Patent CA-2562337-A1 (CA)
Inventor: VAN GEEN ALEXANDER
IPC: G01N33/20
Filed: 2005-02-25
Abstract: A formulation for preparing water samples for determining arsenic concentration by colorimetry is provided. The chemical reagents in the formulation may be provided as premeasured and premixed tablets or pills. The chemical reagents include sulfamic acid, an oxidizer, and color reagents for selectively forming molybdenum-based color complexes with arsenates and phosphates. To test for arsenic, the water samples are acidified by addition of sulfamic acid. Sulfamic acid also advantageously reduces arsenic to an arsenite state. Arsenic in the water sample is oxidized or re-oxidized to an arsenate state by addition of the oxidizer. Then, color reagents are used to selectively bind and convert arsenates and phosphates in the water samples into molybdenum-blue color complexes. The light absorbance of the water sample with both arsenates and phosphates bound in molybdenum-blue color complexes is compared to that of a reference acidified specimen in which mostly only the phosphates but not the arsenates are bound and converted. The differential light absorbance of the two specimens is used to arrive at a quantitative value for the arsenic concentration in the water sample.

Abstract: A method of authenticating a remote service (104) to a user (102) via a communications network (106) is disclosed. The remote service (104) obtains a service authentication code that has been generated, using a code generation algorithm, based on a first secret key. The service authentication code is communicated to the user (102) via the communications network (106) and received, or entered, into an authentication device (106) associated with the user (102). The authentication device (106) then generates, using the same code generation algorithm, an expected code value based on a second secret key and compares the expected code value to the service authentication code.  Responsive to the comparison, and in the event that the expected code value correlates with the service authentication code, the authentication device (106) generates a response that indicates to the user (102) the authenticity of the remote service (104).

Filed: 2002-09-12
Abstract: A hand brake system (40) for a rail vehicle providing a hand brake position alarm (76) before a train is moved with a hand brake not fully released. A switch (56) detects the position of a hand brake drive chain (18) to provide a brake engaged signal (60). The weight of the drive chain is supported through a load path that bypasses the switch. A master controller reverser handle position detector (74) provides a reverser handle position signal (72) when the reverser handle is moved out of neutral in preparation for providing power to the locomotive drive motors (15). A relay (70) is used to actuate the multiunit wheel slip indicator (54) and the general alarm bell (52) in every locomotive of the train consist when the brake engaged signal is coincident with the master controller reverser handle position signal. This combination of alarms, which normally indicates a locked axle when the train is above a predetermined speed, is interpreted as a hand brake position alarm when the train is at rest.

Title: Electronic ballast having a flyback cat-ear power supply
Inventor: VESKOVIC DRAGAN
IPC: H05B37/00
Filed: 2006-04-27
Abstract: An electronic ballast for driving a gas discharge lamp includes a rectifier to convert an AC mains input voltage to a rectified voltage, a valley-fill circuit for producing a DC bus voltage, an inverter for converting the DC bus voltage to a high-frequency AC voltage for driving the lamp, a control circuit for controlling the inverter, and a flyback cat-ear power supply for supplying current to the inverter when the rectified voltage is less than a predetermined level. The flyback cat-ear power supply also provides power to the control circuit. Preferably, the flyback cat-ear power supply draws current only when the inverter is not drawing current directly from the AC  mains, so as to make the input current to the ballast substantially sinusoidal. The result is a ballast having substantially improved power factor and THD. Also, the ballast operates more efficiently because the flyback cat-ear power supply supplies excess energy not needed by the ballast control circuitry to the inverter to be used to drive the lamp.
