Patent CA-1277157-C (CA)
Inventor: EHLIG-ECONOMIDES CHRISTINE
IPC: E21B47/06
Filed: 1986-07-23
Granted: 1990-12-04
Abstract: ABSTRACT OF THE DISCLOSURE         The invention concerns a process for measuring the flow as a function of time of the several layers of a subterranean multilayer hydrocarbon-producing formation through which a well is drilled, and for determining the parameters of formation by comparison of trends in well behaviour shown by actual measurements with trends in behaviour established theoretically.  The flow rate contributions of individual layers are determined from cumulative measurements made above successive layers by a flowmeter moved vertically within a wellbore.  Experimental curves are derived that represent the relative variations in time of the flowrates of layers or groups of layers in the formation using flowrate measurement points obtained when a total flowrate variation has been imposed on the well at a given time between two given constant values.          These experimental curves then compared to theoretical model curves established for various values of the characteristic parameters of a subterranean formation, to determine values of the parameters of the formation.

Granted: 1992-03-10
Abstract: ABSTRACT OF THE DISCLOSURE          Apparatus for either display, or for both display and dispensing, is mounted to shelf tag molding directs customer attention to a featured item in a store as customers approach the area of a shelf on which the item can be found.  The apparatus comprises a frame that is pivotally mounted into a bracket assembly which is rigidly secured to the shelf tag molding.  The frame holds on either side of its surfaces, promotional material that presents a message to the approaching customers.  The apparatus includes biasing springs which position the frame in a steady state location that is normal to the shelf tag molding.  Whenever the frame is deflected from its steady state location by, for example, a customer or a shopping cart moving past and striking it, the biasing springs automatically return the frame to its steady state location.  This ensures that the advertising message appearing on the promotional materials continually remains in direct view of approaching customers.         The display apparatus receives two advertising placards for presentation to approaching customers.         The display and dispensing apparatus includes a removable top cover for bulk loading of promotional material within the apparatus.  Finger-receiving openings formed adjacent the outer bottom corner of the frame facilitate dispensing of the outer sheet of promotional material to a customer.

Title: Noise suppressor for turbo-compressor
Inventor: TOTH DENNIS W
IPC: F04B39/00
Filed: 1987-11-04
Granted: 1991-02-19
Abstract: ABSTRACT OF THE INVENTION         A turbo compressor mounted upon a hollow box-like housing is provided with a noise suppressor which includes a rectangular open ended box-like structure suspended from the housing by flexible walled tubes which constitute an air inlet and an air outlet to the housing through which air flows to prevent heat build up within the housing.  The suppressor walls are lined with a sound absorbent material which, combined with the non-rigid suspension of the suppressor from the housing and the non-linear air entrance and exit paths to and from the housing, suppresses sound generated by flow of high pressure air from the compressor into the housing through a shaft bearing.          Noise generated by the flow of air into the compressor inlet is reduced by blocking the inlet with a block of porous foamed plastic material which also functions as an inlet filter.
