Title: Method and device in acoustic flow measurement for ensuring the operability of said measurement
Inventor: MAEYRAENEN TARMO
IPC: G01F1/7082
Filed: 1993-03-25
Abstract: ABSTRACT OF THE DISCLOSURE    Method and device for acoustic flow measurement for measurement of the flow velocity of gases and/or of quantities derived from same.  A long-wave sound is transmitted into the measurement pipe and, by means of two sound detectors placed at a certain distance from one another in connection with the measurement pipe, the sound signals that propagate in the gas flow downstream and/or upstream are detected, the flow velocity of the gas that flows in the measurement pipe being determined by means of correlation of said sound signals.  A sound speed C0(T) in a medium at rest, which sound speed has been standardized or will be standardized for a certain temperature, is stored in the memory, and the flow velocity and the outer quantities that may be derived from same, if any, are computed, at least in situations of disturbance, by means of the detected downstream speed vd or of the detected upstream speed Vu and by means of said sound speed at rest c0(T) stored in the memory.

Title: Method and apparatus for manufacturing a container filled with a product
Inventor: LINNER HANS
IPC: B29C65/00
Filed: 1992-09-02
Abstract: The invention provides a method for manufacturing a container filled with a product (11), and comprising a substantially tubular body portion (10) of thin-walled plastic or laminated plastic material and a butt-weldable end-piece (13) at each end of the body portion. A first end-piece is fitted to one end of the body portion and the product (11) is introduced into the container via the open end of the body portion. A second end-piece (13) having a transverse wall (15) of diameter slightly less than the diameter of the tubular body portion (10) is then introduced into the said open body portion end to an intermediate position where it partially projects into the body portion (10). The plastic material of the body portion end region and the second end-piece is softened through application of heat energy. The method is characterized in that the end-piece (13) is contacted by an abutment member (18) of lesser diameter than the transverse wall (15) and, by means of relative displacement between it and the body portion (10), the end-piece is pressed in to the body portion to its terminal position whilst a cooling medium is supplied to the abutment member (18) for preventing the abutment member from adhering to the transverse wall (15) and which cooling medium does not directly act on said transverse wall. The invention also provides an apparatus for carrying out the above method.

Title: Automatic control for an air conditioner
Inventor: PAUSTIAN JOHN K
IPC: F24F11/76
Filed: 1994-06-20
Abstract: ABSTRACT OF THE DISCLOSURE An automatic control for an air conditioner having a compressor motor and a fan motor and a method for its operation are provided. While the control operates both motors to cool an enclosed space, a temperature indicative of the air temperature in the space is sensed and compared with a first preselected temperature value. When the sensed temperature is no longer greater than the preselected temperature, operation of the compressor motor is terminated. Thereafter the fan motor is operated for a first preselected time period. During the first time period, a currently sensed temperature indicative of the air temperature in the space is compared with a second preselected temperature value. When the sensed temperature is no longer less than the second preselected temperature during the first time period, operation of the compressor motor is resumed and the process described above with respect to cooling the space is repeated. Upon an expiration of the first time period without exceeding the second preselected temperature, operation of the fan motor is terminated. Thereafter a second preselected time period is initiated. After expiration of the second time period, a currently sensed temperature indicative of the air temperature in the space is compared with a third predetermined temperature value during a third predetermined time period. When the sensed temperature is no longer less than the third preselected temperature during the third time period, operation of the fan motor is resumed, the first time period is restarted and the operation described above with respect to the first time period is repeated. Upon an expiration of the third time period without exceeding the third preselected temperature, the second time period is restarted and the operation described above with respect to the second time period is repeated.

Patent CA-2128481-A1 (CA)
Inventor: SLEVINSKY BRUCE A
IPC: E21B49/00
Filed: 1994-07-20
Abstract: A method is provided for establishing the location and orientation of the boundaries surrounding a subterranean reservoir and creating an image thereof. A conventional pressure test is performed on a well, establishing measures of the well's pressure response as defined by the rate of pressure change in the reservoir over time. Conventional techniques are used to determine measures of the radius of investigation. A calculated response for an infinite and radially extending well and the measured response are compared as a ratio.  Variation of the ratio from unity is indicative of the presence of a boundary and its magnitude is related to an angle-of-view.  The angle-of-view is related to the orientation of the boundary to the well.  By combining the angle-of-view and the radius of investigation, one can define vectors which extend from the well to locations on the boundary, thereby defining an image of the boundary.  In an alternate embodiment, the angle-of-view and radius of investigation can be applied in a converse manner to predict the pressure response of a well from a known set of boundaries.
