Patent CA-2167083-C (CA)
Title: A method and apparatus for testing the thermal stability of an (aviation) fuel
Inventor: CLARK RICHARD HUGH
IPC: G01N25/02
Filed: 1994-07-13
Granted: 2005-02-01
Abstract: A method and apparatus for testing the thermal stability of an (aviation) fuel. Under pressure a fuel sample to be tested is supplied to a small-bore capillary tube (2) of a test section and the fuel in the tes t section is allowed to be heat stressed. The fuel sample in the test section is under turbulent flow regime. The thermal degradation of the test fuel within the section is monitored by measuring by means of contactless thermometry the outer wall temperatures along the test section a nd subsequent increases in these temperatures, promoted by the insulation effect of fuel degradation products. From the temperature data, thus obtained, information on the thermal stability of the fuel is derived.

Title: Method and circuit for operation of a high-pressure discharge lamp
Inventor: OSTERRIED JOSEF
IPC: H05B41/288
Filed: 1996-03-01
Granted: 2005-05-10
Abstract: To increase the operating efficiency of an operating circuit for a high-pressure discharge lamp (LP), current is supplied to the discharge lamp in discontinuous mode, that is, in pulses which start from a zero or null current level when the lamp is operating in normal state. Current flow through a choke coil (LD), which alternately stores and releases energy, is sensed, and a new energy pulse is supplied only when the current through the choke coil has decayed to zero or null, by controlling a pulse width modulation circuit (P2) which, in turn, controls a transistor (T2) which, in turn controls current flow through the coil (LD). The transistor (T2) is a field effect transistor which has its source terminal connected to the negative terminal of an intermediate coupling capacitor (C1) forming part of the power supply for the lamp. A free wheeling diode (D1) is provided, connected to the positive terminal of the intermediate circuit capacitor (C1). After energization, and ignition of the lamp, the lamp is operated in continuous mode, with continuous current flow, to shorten the run-on or warm-up period thereof, switch-over to the discontinued mode operation being gradual as voltage and current supplied to the lamp reach normal operating state.

IPC: G01M3/24
Filed: 1996-04-10
Granted: 2001-01-16
Abstract: A portable computing device is used for acoustic testing of valve systems for valve leaks. Transducers are applied to appropriate locations in the valve system to obtain sound signals, which are fast Fourier transformed into valve signatures. Multiple signatures are displayed simultaneously and are compared automatically by the system to derive a recommended result and manually to make determinations of valve leaks by the differential signature method or the like. The signatures and the user's determinations are stored on a hard drive. Various panels are displayed to give the user step-by-step instructions for performing the test. Thus, training is simplified, use of paper is vastly reduced or eliminated entirely, and the results can be ported to the client's office computers.

Filed: 1997-04-23
Granted: 2000-08-22
Abstract: The present invention relates to a method of synchronizing CDMA processing in a satellite communication system connecting multi-point ground stations. The method is comprised of the steps of acquiring access and synchronization signals transmitted by a satellite at a terrestrial subscriber unit, setting a reference propagation delay time, and establishing a propagation delay in terms of arrival of a message in relation to one of a plurality of quantified timing marks subsequent to the reference propagation delay time, when the satellite receives a first signal from the terrestrial subscriber unit on an access channel. The method further comprises the steps of conveying the established quantified propagation delay to the terrestrial subscriber unit, adjusting timing of uplink CDMA code chips at the terrestrial subscriber unit from the original reference propagation delay derived from the access channel, tracking synchronizing by adjusting code delay of the uplink arrival time of a reference code, and retaining synchronization by downlink code delay transmission.
