Patent CA-2066707-A1 (CA)
Title: Temperature transducer
Inventor: BLAKE GRAEME A
IPC: G01K7/32
Filed: 1991-07-19
Abstract: A vibrating crystal transducer for measuring temperature including a bonding area from which three or more tines extend. The tines have a torsional mode resonant frequency that is a function of temperature. Electrodes on the transducer excite the tines into vibration so that the torsional moments of the adjacent edges of the adjacent tines are reverse symmetric. When the tines are vibrated, the reverse symmetrical vibrational moments of the individual tines cancel so that there is no torsional moment, or twisting, within the area between the points where the tines intersect, which is the area defined by the bonding area. Since the bonding area does not serve as a sink for torsional energy, torsional energy is not lost through the bonding area so that the transducer has a relatively high quality factor and torsional vibration of the transducer cannot cause the transducer to eventually work loose of a mounting pad to which it is attached.

Inventor: LIMA WILLIAM
IPC: B65D39/08
Filed: 1992-10-09
Abstract: A drum liner locking and locating apparatus is provided for securing a drum liner to a drum.  The drum liner apparatus primarily comprises a fitting, a liner, and a non-releasable securing means.   The fitting is passed through an opening in the lid of a drum before the lid is attached to the drum.  The fitting can only be passed through the opening so that the liner is in a position that the liner can expand to the full size of the drum.   After the fitting is  in place,  the non-releasable securing means fastens the fitting to the drum raising  the  drum  liner  to  the  top  of  the  drum. Consequently, to remove the drum liner, the top of the drum must be removed destroying the drum and prohibiting reconditioning or reuse of the drum.

IPC: F22G5/20
Filed: 1993-05-28
Abstract: A reheat steam temperature control system that utilizes the separate components of a reheater and a reheat heat exchanger to generate hot reheat steam.  The reheater uses the fluidized bed as its source of heat while the reheat heat exchanger uses main steam as its source of heat.  A bypass control valve is operated to divert the required amount of main steam to the reheat heat exchanger  depending  on  operating  conditions.    Should  the temperature of the hot reheat steam be too low, additional main steam is delivered to the reheat heat exchanger.   Conversely, should the temperature of the hot reheat steam be too high, the amount of main steam delivered to the reheat heat exchanger is reduced.   Attemperators  are  used  within  both  the  reheating circuit and the main steam circuit to temper the fluctuations of their respective steam.
