Title: Method and apparatus for improved oil recovery of oil and bitumen using dual completion cyclic steam stimulation
Inventor: BEATTIE CRAIG I
IPC: E21B36/00
Filed: 1993-02-18
Abstract: A method and apparatus whereby recovery from heavy oil and bitumen reservoirs may be increased over that achieved in the later stages of cyclic steam stimulation (CSS) operations.   Two sets of perforations perforate a steam chamber in a reservoir surrounding a well.  The two sets of perforations are isolated hydraulically from each other within the casing by a thermal packer.   Steam is then injected down the casing annulus into the upper set of perforations.   After  a period of  steam  injection, steam injection is halted and hydrocarbons are produced from the lower set of perforations through one of two strings of tubing extending through the thermal packer.          The  second  string  of  tubing  serves  to vent the well during production.  This process may be repeated over the life  of  the  well,  alternately  injecting  steam  and producing hydrocarbons.

Title: Clean burning burner, particularly for combustion of gasified liquid fuel, such as fuel oil, or of gas
Inventor: FULLEMANN JORG
IPC: F23D11/40
Filed: 1993-02-23
Abstract: ABSTRACT OF THE DISCLOSURE. To provide for complete gasification of liquid fuel admitted by an atomizing nozzle (11, 13), located axially with respect to an air inlet opening (55) in an inlet diaphragm, a deflection element (31) is located spaced from the air inlet in order to deflect the mixture of air, recirculated combustion gases and gasified fuel in approximately radial direction.  A flame tube (21) surrounds the burner, with space,  to form a first (I) recirculation path for hot gases, deflected by the deflection element back towards the inlet of a recirculation space formed between the air inlet and the deflection element. In accordance with a feature of the invention, a second recirculation path  (II)         extends through openings (57, 61, 59) in the recirculation element, into the   deflection  element itself which, preferably, is a hollow, essentially conical deflection structure directing the flame which forms radially outwardly from the flame tube.  This will cause suction to arise with respect to the interior of the deflection element (31), to re-circulate gases back into the gasification space (66) between the air inlet and the deflection element, and also heating the deflection element.  Thus, all structural elements, such as an air inlet diaphragm (35), the deflection element  (31), optionally a gasifier tube (17) and the flame tube (21) are subjected to recirculated hot combustion gases, so that no drops or droplets from the atomizing burner (133 can adhere, and burn on or coke on the structural elements.  The complex combustion and stream relationships, caused by the braking  or back-damming effect of the recirculation element, and eddies and turbulences arising from over-pressure air supplied to the air inlet (55), result in effectively complete gasification of fuels within the gasification space (66) even if no real gasifier is present. The flame, expanding in radial direction due to the deflection element, burns blue, with practically no NOx formation, and effectively devoid of unburned hydrocarbons.

Title: Radio receiver for forming a baseband signal of time-varying frequencies
Inventor: SANECKI THEODORE T
IPC: H03D7/16
Filed: 1992-11-06
Abstract: A radio receiver, and associated method therefor, for generating a baseband signal having signal component portions of time-varying frequencies. The oscillating signal generated by at least one of the low oscillators of down-mixing circuitry (680, 744, 750) of the receiver is modulated by a low-frequency signal thereby to cause the resultant, baseband signal to be comprised of signal component portions of time-varying frequencies. Because the signal component portions of the baseband signal are of time-varying frequencies, attenuation of such signal component portions and resultant distortion of the received signal, as a result of undesired notches in the frequency response of a radio receiver is avoided.

Title: Analyzing an image showing editing marks to obtain category of editing operation
Inventor: MAHONEY JAMES V
IPC: G06V30/40
Filed: 1994-10-14
Abstract: Input image data define an input image set that shows a graphical feature and editing marks indicating an editing operation to be performed on the graphical feature. The input image data are used to obtain operation category data indicating whether the editing operation would translate the graphical feature so that it is centered at a different position within the input image set. The operation category data are used to obtain output image data defining an output image that includes an edited version of the input image set. The output image shows the graphical feature centered at a different position only if the operation category data so indicate. The input image set can include an original image showing the graphical feature and an overlay image showing the editing marks. The editing marks can form a node-link structure with the graphical feature. If the structure is a directed graph, it can indicate an editing operation that would translate the graphical feature to be centered at a different position, such as a simple translation to a new position, a translation with scaling or rotation, or a replacement operation. If the structure is an undirected graph, it can indicate an editing operation that would not translate the graphical feature, such as a delete operation or a scale or rotate operation. A rectangle with a dot inside it can indicate scaling or rotation. A cross can indicate deletion.

Title: Improved surface-enhanced raman optical data storage system
Inventor: VO-DINH TUAN
IPC: G11B7/0045
Filed: 1992-10-05
Abstract: An improved Surface-Enhanced Raman Optical Data Storage System (SER-ODS) is disclosed.  In the improved system, entities capable of existing in multiple reversible states are present on the storage device. Such entities result in changed Surface-Enhanced Raman Scattering (12) (SERS) when localized state changes are effected in less than all of the entities. Therefore, by changing the state of entities in localized regions of a storage device, the SERS emissions in such regions will be changed. When a write-on device is controlled by a data signal, such localized regions of changed SERS emissions will correspond to the data written on the device.  The data may be read by illuminating the surface of the storage device with electromagnetic radiation (36) of an appropriate frequency and detecting (40) the corresponding SERS emissions. Data may be deleted by reversing the state changes of entities in regions where the data was initially written. In application, entities may be individual molecules which allows for the writing of data at the molecular level. A read/write/delete head (32) utilizing nearfield quantum techniques can provide for a write/read/delete device (32) capable of effecting state changes in individual molecules, thus providing for the effective storage of data at the molecular level.
