Abstract: ABSTRACT OF THE DISCLOSURE         A window frame, especially for ventilation  by setting at various angles a plurality of slats  mounted on said frame is disclosed, the improvement consisting in that the control lever which acts upon the rod which gangs the slats  for setting them at an angle together has the end pointing towards the interior of the frame in the form of a toothed sector, the points of which engage, in turn, a notch formed on a brace which is removably fastened to the window frame upright.  The mechanism is reliable and versatile since it permits that the slats  may be set at various angles in a stable manner.  Means are also provided for preventing slat rattle by properly  shaping the individual frames of the slat carriers.  Thermoplastics materials are widely used in the construction of the frame and accessories.

Abstract: Abstract of the Disclosure A method is disclosed for processing call data among telephone switching offices and a remotely situated data base system for deriving call service information needed to complete special service calls, such as INward WATS (Wide Area Telephone Service) calls to a destination specified by the derived information.  A network of local and toll offices compiles a special service call message including caller dialed 800 number and an originating area code for the INWATS service and then transmits that message to the data base system over CCIS (Common Channel Interoffice Signaling) facilities including signal transfer systems.  At the data base, the message is translated into a directory-unlisted number identifying an INWATS customer station designated to serve the call.  Before the call is switched through the toll switching network under control of the unlisted number, the open/closed and busy/idle conditions of the INWATS station are checked at the data base to determine the availability of the station to serve the call.  Traffic data is accumulated at the data base by originating area code and by the unlisted INWATS number. When the number of calls to the unlisted number per unit time exceeds a threshold, the data base instructs the telephone system to inhibit such calls from being served for a prescribed period.

Abstract: ABSTRACT       A signal processing system that has an improved modular architecture so that a selected number of arith-metic element (AE) units may be utilized with a single arithmetic element controller (AEC) unit to provide a system that can be readily expanded or decreased on com-putational ability.  All of the AE units perform similar calculations under control of the AEC unit in response to common address control and coefficient signals.  Each AE unit has its own extended work store (EWS) unit with all of the EWS units responding to the same address and control signals, from either the AEC unit or an external interface unit to conform to the modular architecture. Each EWS unit is synchronized with the AE unit, thus allowing continuous and high speed computations to be performed.  Also, each of the EWS units is coupled to the external interface unit for receiving and transferring data when not being accessed by the AEC unit.  The AE units, each of which are similar, may have a single multiplier and storage unit matched to a plurality of register and arithmetic logic (RALU) units so that parallel calculations may be performed utilizing the multiplier output data, thus increasing the overall speed of calculation a plurality of times of the system clock speed.  Another feature of the invention is that the AEC unit has an architecture that allows simplified program-ming.  The processor system also includes a control arrangement that allows, upon failure of an AE unit or EWS unit, a redundant AE unit and EWS unit to be utilized.

Title: Indirect thermal stimulation of producing wells
Inventor: HOLLINGSWORTH FRANK H
IPC: E21B43/243
Filed: 1979-09-14
Granted: 1982-02-16
Abstract: ABSTRACT A well which is to produce from a heavy oil or tar sands reservoir is thermally stimulated from another well located on the order of 10 to 50 feet away.  This adjacent stimulating well can be considered expendable. There are two independent fluid passages in the well, com-municating in the reservoir region with an upper and a lower zone of the reservoir, respectively, for example, through perforations.  Fluid communication in the well is sealed off between the passages.  A divertant such as water or a dilute aqueous soap solution is pumped out into the upper zone of the reservoir, while a thermal stimu-lating gas (e.g., steam or compressed air which causes combustion) is forced out into the lower zone.  This indi-rect thermal stimulation process controls vertical move-ment of steam or combustion gas through the reservoir near the wellbore by flow of the divertant.          The producing well has been prepared through underreaming in the reservoir and installation of a screened high-temperature-resistant liner surrounded by a gravel pack.  Preferably this well is produced during the indirect thermal stimulation to remove as far as possible the heated heavy oil or tar in the zone stimulated by the expendable well.          If it is desired to hydraulically fracture the lower zone in this adjacent well, the upper perforations may also be used, since flow of divertant at this time tends to promote horizontal fracturing relatively low in the formation.          This thermal stimulation is continued for a number of days, until the hot zone produced extends beyond the location of the producing well.  Thereafter, the adja-cent well preferably is closed off during the course of the frontal thermal drive or the like from remote injec-tion wells.  However, such stimulation may be repeated later on if the oil or tar becomes too viscous in the pay zone near the producing well.

Abstract: ABSTRACT    The invention provides head-coupled area-of-interest visual display apparatus particularly for ground-based craft-flight simulators.  The apparatus provides binocular, pseudo-collimated vision of a display, projected onto a part-spherical retro-reflective screen, for two pilots, covering an area of interest centred upon each pilot's line of view.  A separate image generator is used for each pilot and may both be of the computer generated image, laser-scanned model or closed-circuit television type.  for the pseudo-collimated viewing, the same image is projected for left and right eyes for each pilot from points on a respective pilot helmet, horizontally in line but vertically displaced above the pilot's eye position.  Line scan apparatus is mounted in the pilots' cockpit; line image transmission is by fibre optic light guide ribbons; and frame scan apparatus is mounted on the two pilots' helmets.  Sensing means detect head/helmet movements of each pilot to permit voluntary individual scanning of a wide angle of simulated view from the craft.
