Abstract: PATENT                  HYDROCARBON WELL TEST METHOD             Inventors: MM. J. AYOUB and D. BOURDET                 ABSTRACT OF THE DISCLOSURE      The invention relates to a well test method for de-termining the physical characteristics of a system made up of a well and a subsurface formation containing a fluid such as a hydrocarbon. A change in the flow rate of said fluid is produced for a short period (duration tp of the order of a few minutes) so as to obtain a flow pulse re-sembling a Dirac pulse; the variations .DELTA.P of the down-hole fluid pressure is measured during said short period and then during the subsequent period of return to the initial state of the well-formation system, and the experimental pressure curve thus obtained is compared with the curves of a double network of type curves representing, as a function of a common parameter, the pressure PD and its derivative P'D with respect to time, by matching the branch of the experimental curve corresponding to the short period with a curve PD and the branch of this curve corresponding to the subsequent period with the curve P'D of the same parameter.

Title: Process for producing a gas-tight, sealed alkaline  battery
Inventor: GLOETZL KARL
IPC: H01M10/34
Filed: 1985-09-13
Granted: 1989-08-15
Abstract: ABSTRACT OF THE DISCLOSURE     The cell of a gas-tight alkaline battery is balanced by subdividing the negative excess capacity into the necessary charge and discharge reserves by individually treating the two electrode polarities prior to their assembly, while avoiding open cell forming.  When combining a charged, dried, positive sintered electrode which is suitable for storage with a negative electro-deposited electrode, the latter inherently receives a charge reserve due to partial chemical oxidation with H2O2 or K2S2O8.  When a discharged, but preformed positive sintered electrode is combined with a negative sintered electrode, the latter is electrochemically partially charged to the extent necessary to achieve the desired discharge reserve, and thereafter preserved by immersion in a solution containing sulfuric acid, and possibly CdSO4.

Abstract: ABSTRACT   A heavy equipment tire rim is constructed almost entirely from stock shapes of metal.  A base portion is a right cylinder with attachment points to attach the cylinder to the wheel of the equipment welded inside the cylinder at appropriate points.   Flat  radial annular disks are welded to the cylindrical base and support a steel cone having a cone angle of 15 degrees from the surface of the cylinder to support the tire bead.  There are at least two disks for each cone to support the cone at its smallest diameter and at its largest diameter.  If the size and weight of the equipment makes it appropriate additional intermediate disks may be used in one version of the wheel.  In another version of the wheel bar stock is cut into lengths which span the diagonal between the base of the outermost annular disk where it meets the cylindrical base and the periphery of the smaller radial disk where it meets the smallest circumference of the cone.  The bars are welded in place in a closely spaced annular series.  Finally, the tire bead stop is welded to the outer  circumference of  the cone or  to a cylindrical skirt extending the outer circumference of the cone.  The stop is made of standard bar stock of a radius sufficient to properly retain a tire bead.  The stock may be round, semi-round, or quarter-round.  In each case the tire bead itself is retained by a arch which is a quarter of a circle.  All of the stock used to construct the tire rim is stock steel shapes with the exception of  the cone  leading to great  economies of manufacture and to the unobvious result  that all of the parts are in compression rather than tension and the strength of the wheel rim is greatly increased over similar wheel rims known to the art.

Abstract: A B S T R A C T               Method of Fabricating a Self-Aligned Metal-Semiconductor FET      A method for the fabrication of self-aligned MESFET structures  (30)  with  a  recessed  refractory  submicron gate.  After channel  formation  (32)  on a  SI  substrate (31), which may consist of a III-V compound semiconductor such as GaAs, with subsequent annealing the refractory gate  (33G) is deposited and patterned. This is followed by the overgrowth of a highly doped contact layer of e.g. GaAs using MOCVD or MBE processes resulting in poly-cry-stalline material over the gate "mask" and in mono-cry-stalline material  (34S,  34D)  on exposed  semiconductor surfaces. Next, the poly-crystalline material is removed in a selective etch process, this step being followed by the deposition of source and drain electrodes (35S, 35D). In order to further improve process reliability, insulat-ing sidewalls  (43-43)  can be provided at the vertical edges of the gate (33G) to avoid source-gate and drain-gate shorts.

Abstract: AUTOMATIC LIGHT SIGNALLING SYSTEM     Abstract.     An alarm actuated emergency light signalling circuit to replace the usual wall mounted light switch. The new switch circuit fits within the electrical wall box and has the external appearance and manual operation of an ordinary light switch. When triggered by an alarm system, the new light signalling circuit overrides the circuit breaking function of the light switch and causes the lighting controlled by the switch to flash intermittently. The flashing of the lighting occurs regardless of the initial state of the light switch, whether on or off. The circuit includes a low voltage portion driven by the alarm and including sensing and timing circuitry. The low voltage circuit does not require or use any electric power when not actuated by the alarm. The alternating current power circuit for the lighting is operable in the conventional on/off fashion unless actuated by the alarm and low voltage circuit. Thus, there is no additional alarm position for the switch. The flashing circuit is always ready to be actuated by the alarm and requires no manual set or reset action.     1a

Abstract: ABSTRACT            AUTOMATED BITMAP CHARACTER GENERATION FROM OUTLINES    An outline representation of a character or symbol is treated as being composed of a hierarchy of zones formed in both the horizontal and vertical directions.  The zones are completely character-specific.  Each zone defines the extent of some feature of the character.  The boundaries of the zones are mapped to specific pixel locations in a bitmap em-square of selected resolution and size. The available pixels are then allocated to the zones.  After each level of zone has received its pixel allocation, the pixels assigned thereto are then distributed among the next lower level of zones and the process is repeated iteratively until all zones have received their pixel allocations or it is no longer possible to make allocations.  To maintain relationships between features, features of characters (both within individual characters and between different characters) may be linked so as to be defined in terms of the features of the same or other characters.  The features are linked at the outline description level, so that the linking need be specified only once and will thereafter be useful any time a bitmap is to be generated from the outline.
