Abstract: "STEAM DRIVE/OIL RECOVERY PROCESS INVOLVING            HORIZONTAL BOREHOLES"                   ABSTRACT OF THE DISCLOSURE           Vertical injection and production wells penetrating a heavy oil reservoir are interconnected with one or more generally horizontal boreholes.  Each such borehole is packed with a particulate filling having only a limited permeability.  The filling may, for example, consist of frac sand. The filling has sufficient permeability so that steam may be injected thereinto at conventional steaming rates without exceeding the formation fracturing pressure.  However the permeability is sufficiently low so that there is a substantial pressure drop which occurs across the length of the borehole as the steam is pumped through it.  When steam is so injected through the packed borehole, heat penetration into the surrounding reservoir is improved and the concentration of oil in the produced fluid is increased, relative to the results obtained if the borehole is not filled and provides a highly permeable passage for the steam.

Abstract: IMPROVED METHOD AND APPARATUS FOR   USE WITH VORTEX FLOWMETERS          Abstract of the Disclosure A method and apparatus for increasing the resolution and accuracy of flow measurements made by vortex flowmeters. A signal conditioning circuit connected to a vortex sensor generates a vortex signal having a period that varies with the frequency of the vortex street.  The period of this vortex signal is measured by a period sampling circuit, which generates a vortex period signal.  When a programmable control circuit determines that the change in the frequency indicated by successive values of the vortex period signal is relatively small, the displayed flow value is based on the current frequency of the vortex signal; when the change in frequency indicated by successive values of the vortex period signal is relatively large, the displayed flow value is based on the running average frequency of the vortex signal.

Abstract: A computer having a file management system and a plurality of objects is presented.  The file management allows for the coordination  the transfer of data between objects.  A link with a view may be created between a child objects and a parent object as follows.  A user specifies to the child object the data to be displayed.  The user specifies to the parent object a location in which the data is to be displayed.  The user causes the file management system to link the child object and the parent object, so that link data structure includes a reference name which identifies the link data structure, a reference to the child object, a reference to the parent object and a data identifier which identifies the data to be transferred.    Upon request from the parent object, the child object displays the data in the location specified by the parent object.  The request is made by the parent object by sending to the file management system the reference name, a location where the data is to be displayed and a request for the transfer of data.  The parent object does not identify the child object or the data identifier.  It is not necessary for the parent to know these.    When the file management system receives the request from the parent object it sends a request for the transfer of the data to the child object.  This request includes the location where the data is to be displayed and the data identifier.  It does not include the reference name of the identification of the parent object. The child object then displays the data at the specified location.    Alternatively, when the link is set up, the child object may set up  a snapshot object.  The snapshot takes over responsibility to display the data at the specified location.  When the file management system receives the request from the parent object it sends a request for the transfer of the data to the snapshot rather than the child object. The snapshot then displays the data at the specified location.
