Title: Live well deployment of electrical submersible pump
Inventor: BEARDEN JOHN L
IPC: E21B33/068
Filed: 2000-02-24
Abstract: A method for installing a submersible pump assembly that allows deployment in a live well under pressure. In some of the embodiments, a pressure barrier is installed in the well lower than a length of the submersible pump assembly. The submersible pump assembly is lowered on a line into the chamber, then a lubricator at the surface seals around the line by allowing the pressure barrier to be released and the submersible pump assembly to be lowered into the well to a desired depth. Preferably, there is a lower pressure barrier in the well. The upper pressure barrier may be a packer that may be collapsed and retrieved alongside the submersible pump assembly. The pressure barrier also may be a packer that is temporarily set in the well, then engaged by the submersible pump assembly, with the pump assembly and packer then being lowered as a unit to a further depth in the well.
Patent CA-2300540-A1 (CA)
Inventor: HAMMOND STEPHEN VICTOR
IPC: G01N21/35
Filed: 2000-03-07
Abstract: A method of analysing powder formed as a mixture of pharmaceutical ingredients and derived from a bulk preparation of powder by spectrophotometric analysis utilising transmission measurements. A sample powder is removed from the bulk mixture and pressed into a test wafer and spectrophotometrically analysed for the transmitted beam to provide an assay test spectrum of actual absorption characteristics of ingredients in the material of the wafer. These characteristics of the assay test spectrum are compared with predetermined assay standard spectra determined from individual standard wafers for each relevant ingredient in the powder mixture by measuring absorption characteristics of the individual ingredients from the transmitted beam at known wavelengths of the beam to assess acceptability of the homogenity and distribution of the relevant ingredient in the powder of the sample. The wafer is preferably pressed with flat and parallel opposed end faces through which the beam is directed.

Patent CA-2314190-A1 (CA)
Inventor: ANDERSON JASON S
IPC: F24H9/20
Filed: 2000-07-20
Abstract: A control and method for preventing dry start of an electric water heater provides activation of a bottom heating element for a short time and then senses the temperature to detect the absence or presence of water around the bottom heating element. In the absence of water, the control prevents further activation of the heating element. If water is present, the bottom heating element is activated to heat the water to a set point temperature. An additional upper heating element is activatable only after its temperature falls a predetermined amount below the set point temperature. The control may also include a programmable time having the ability to vary the turn off set point temperature in a predetermined manner during different times of a given day and/or week as well as to provide a convenient way to maintain a reduced turn off set point temperature for an extended period of time.

Title: A silenceable speaker with pre-announce tone detection
Inventor: LE BEL VINCENT VICTOR
IPC: G08B7/06
Filed: 2000-10-13
Abstract: An alarm signaling device (5) operable to produce an alarm signal and, possibly, communicate emergency announcements when triggered by a signal from a central alarm control panel. The alarm includes a speaker or other sound producing device and a silencing circuit (14) that can be engaged by a person in the room to temporarily disable the speaker. The silencing circuit includes a timing circuit (30) and a switch (32) consisting of a pair of touch contacts (38, 40) that are activated by body resistance. The timing circuit (30) is operable to automatically re-enable the speaker after a predetermined time period has been measured. Furthermore, though the speaker has been silenced by the silencing circuitry (14), a reactivation circuit (15) continues to receive and process signals in order to identify a re-enablement signal by its particular frequency and duration. Once the re-enablement signal has been identified, the reactivation circuit (15) automatically overrides the silencing circuit (14) so that alarm signals or emergency announcements may be communicated.
