Patent CA-2124975-A1 (CA)
Inventor: KASAHARA MASATAKA
IPC: H01T1/14
Filed: 1994-06-02
Abstract: A gas-tube arrester includes an arrester body in which an inert gas is contained, and first and second electrodes face each other separated by an insulator. An insulating, heat-resistant film is in contact with the first electrode and has a plurality of small holes. A low-melting point metal plate layered on the insulating film has a melting point lower than a decomposition or softening temperature of the insulating film. A conductive leaf spring electrically connected to the second electrode presses the low-melting point metal plate toward the insulating film, so that, when a high voltage is applied between the first and second electrodes, an electrical discharge occurs between the first and second electrodes through the small holes of the insulating films. The leaf spring has an extend portion bent toward the first electrode, so that, if the low-melting point metal plate is melted by heat from the arrester body, the melted metal will electrically connect the extended portion of the leaf spring to the first electrode.

Title: Method for regulating a gas-turbine assembly equipped with two combustion chambers
Inventor: FRUTSCHI HANS U
IPC: F02C9/00
Filed: 1994-08-09
Abstract: ABSTRACT OF THE DISCLOSURE In  a  method  for  regulating  a  gas-turbine assembly,  essentially consisting of a compressor unit (1), of an HP-combustion chamber (4), of an HP-turbine (6), of an LP-combustion chamber (9), of an LP-turbine (12)  and of a generator (14), the rating of the fuel quantity  (FH)  for  the  HP-combustion  chamber  (4)  is carried out by means of a corrected temperature signal which is formed by the value of the temperature (T13) at the outlet of the LP-turbine (12), reduced by the particular temperature rise (.DELTA.T) detectable there. This temperature signal (T13 - .DELTA.T) is recorded in that the temperature rise  (.DELTA.T)  generated by the fuel quantity (FL)  introduced into the LP-combustion chamber (9) is subtracted from the measured temperature at the outlet of  the  LP-turbine  (12).  The  uncorrected temperature signal at the outlet of the LP-turbine (12) is used for rating the  fuel  quantity  (FL)  for the LP-combustion chamber (9).                        (Figure)

Patent CA-2133392-A1 (CA)
Inventor: KIEFER GERRY D
IPC: B29C44/34
Filed: 1994-09-30
Abstract: A device for molding foam products comprising upper and lower portions cooperable to form a foam mold defining a mold cavity therein.      The upper mold portion has at least one vent hole therein. A mechanism for providing the mold cavity with an expandable foam during a filling cycle is also provided. The expandable foam reactively expands when provided within the cavity so as to be molded into the shape of the cavity during a foaming cycle. The foam approaches the vent hole while expanding within the mold cavity during the foaming cycle. At least one vent hole provides a passage through which air and reaction product gases introduced into the cavity as a byproduct of the reactive expanding of the foam can escape to atmosphere from the cavity during the foaming cycle.      A sensing and signal generating assembly detects the presence of the foam at a predetermined proximity to the at least one vent hole during the foaming cycle and generates a signal in response to the detection.      Finally, a sealing mechanism cooperates with the at least one vent hole to close the passage when the sensing and signal generating assembly generates the signal in response to the detection of the foam at the predetermined proximity to the at least one vent hole to prevent the foam approaching the vent hole from escaping the cavity through the passage.

Title: Time correction of an electronic clock
Inventor: KOMODA MOTOYOSHI
IPC: G04G5/00
Filed: 1995-05-19
Abstract: An electronic clock comprises a usual oscillator and a more accurate oscillator. The usual oscillator generates a first frequency which causes the electronic clock to operate and the more accurate oscillator generates a second frequency which is used as a reference frequency.  Referring to the second frequency, the first frequency is measured by a frequency measurement circuit and a deviation of the first frequency from a design frequency is calculated by a processor.  According to the deviation, time correction of the electronic clock is performed.  Therefore, even if an actual oscillation frequency of the usual oscillator is not stable precisely, the accurate time correction can be achieved.
