Title: Method for improving productivity of a well
Inventor: HOWELL DAVID ATKINSON
IPC: E21B41/00
Filed: 1995-08-09
Abstract: A method for improving the productivity of a well by separating and disposing of at least a portion of the water which is produced from a subterranean producing formation.  The water is allowed to separate from the produced fluids under the influence of gravity while in the wellbore.  The separated water is then disposed without removing it from the wellbore by flowing it into a subterranean disposal formation which has a pressure less than that of said producing formation.  Preferably, the well is completed with an inclined wellbore which significantly aids in the gravity separation of the water from the produced fluids (e.g, hydrocarbons).

Title: Non-recirculating, die supplied doctored roll coater with solvent addition
Inventor: MCCOLLAM ROBERT P
IPC: G11B5/842
Filed: 1994-06-30
Abstract: A coater incorporates a die (42), a reservoir (46), a gravure cylinder (48), and a doctor blade (50) for applying coating fluid to a moving surface (44). The flow rate of coating fluid to the gravure cylinder (48) is controlled to equal the rate at which coating fluid is consumed by the coating process. This eliminates the need to recycle surplus coating fluid. The coating fluid can be quickly and conveniently replaced with a solvent in the reservoir (46) when coating is not being performed to reduce the occurence of coating defects arising from excessive evaporation of solvent and premature solidification of coating fluid.

Par exemple, un réglage de +/- 1/2 degré peut être effectué au niveau de l'angle de la pale par rapport au moyeu pour s'assurer que les erreurs d'attaque/de traînée sont réduites. Dans un autre mode de réalisation, l'ensemble amortisseur comporte des cales métalliques allongées (49a, 49b) adjacentes aux nappes stratifiées d'extrémité des amortisseurs supérieur et inférieur, de telle manière que ces cales peuvent être boulonnées sur les plaques terminales des ensembles amortisseur afin de permettre une augmentation graduelle de leur rigidité. L'appareil décrit permet de régler chaque pale du rotor afin d'équilibrer l'ensemble rotor pour réduire au minimum les vibrations.

Abstract: There is provided a skin substitute that can suitably be used for covering the surface of a damaged skin area which is typically a wound produced by a traumatic local loss of the skin of the human body as a result of a burn or some other cause of damage. It is a skin substitute of a laminate comprising a squid chitin sheet and a fish skin collagen coat layer, which may be a salmon skin collagen coat layer. Such a skin substitute effectively exploits the suppleness and the effect of proving an environment for encouraging the production of lysozyme and defending the wound of squid chitin and, at the same time, compensate the disadvan-tage of poor adhesion of fibroblast cells that operate for curing the wound.  Additionally, the fibroblast cells adhering to a laminate of a squid chitin sheet and a fish skin collagen coat layer showed a normal cell proliferation curve without any delayed initial rising phase to prove the former more satisfactory that cannot be expected from a laminate comprising a calf skin collagen coat layer.  Finally, a DNA labeling index substantially equal to that of fibroblast cells of  normal human skin was observed.

Title: Removable securable cargo area cover especially for use on utilities and pick-up trucks
Inventor: DEBONO GREGORY JOHN
IPC: B60J7/08
Filed: 1996-06-28
Abstract: A securable and removable cover for vehicle with an open cargo area such as a pick-up truck that has a front wall, tailgate and two side walls, the cover comprising of two panels that are hingedly attached to each other at their inside edge along a hinge connection and which span across the cargo area so as to enclose it. The covers generally span across from the tailgate to the front wall with the outer edge of each panel resting on top of a side wall. A securing means then secures the outer edge of each panel to the side wall on which it is resting when the panel is in a resting position. So as to prevent the cover from being moved vertically there is a restraining means engaging the cover and preventing it from being moved vertically when at least one panel is lying flat across the cargo area. To remove the cover, both panels are folded upwards until the restraining means is disengaged and the cover is then simply lifted upwards removing it from the pick-up truck. Further improvements may include restricting means that prevent the cover from sliding when at least one of the panels is closed.

Title: Method and circuit arrangement for detecting speech in a telephone terminal from a remote speaker
Inventor: ROZINAJ GREGOR
IPC: G10L25/78
Filed: 1996-10-11
Abstract: In communication networks with transmission devices using analog circuitry, because of unadapted 4-wire/2-wire junctions, some of the speech of a local speaker comes back to the local speaker as line echo.  This line echo is neutralized by echo compensators.  However, updating of the filter coefficients of the echo compensators cannot be allowed to occur unless line echoes are received: when speech of the far-end speaker is received, recalculation of the filter coefficients must be precluded. Various possibilities for detecting the speech of a local speaker are well known.  According to the invention, detection of the speech of a far-end speaker is fed back to an attenuation measurement of the transmission path, received speech simulates a reduction in attenuation.  From the difference between the long-time average (Aa(k+l)) and the short-time average (A(k+1)) of the attenuation, it is learned very quickly, by comparison with a threshold (THRe), whether speech is present or not.  The method is also applicable in order to discontinue automatic voice output on the local end by means of duplex voice communication.
