Abstract: An operator interface device is connected to the central control unit of a remotely-monitored security system, which also includes one or more local control units located at monitored sites. A local control unit may initiate a telephone call to the central control unit to alert the operator of an event such as an intrusion at the site. The interface device has a keypad on which the operator can enter commands that are transmitted to the local control unit. A processor in the interface device uses a look-up table, state machine or other predetermined relationship to translate the command entered by the operator into the native or local command recognized by the local control unit.

Abstract: An electrical cable penetration seal apparatus which includes a compliant module having an inner and outer regions of different durometer characteristics. In some forms of the invention the outer region has a higher durometer elastomer and a central region which is made from a lower durometer elastomer. The compliant module has an outer rectangular cross-section and the central region is a cylindrically shaped in some forms of the invention.

Abstract: A fusible, rod-like, graft copolymer having repeating units of the formula: ##STR1## wherein X is (--CH.sub.2 CH.sub.2 CONH--).sub.m or (--CH.sub.2 --CH(CH.sub.3)--O--).sub.n, wherein m has an average value of 5.0 to 35.0 and n has an average value of 1.0 to 30.0.

Abstract: A method, and apparatus for practicing the method, is provided for the transit of one or more cables through an opening in a bulkhead while preventing electromagnetic interference and electromagnetic pulse energy from passing through the opening. A housing of electrically conductive material is positioned in the opening and secured around its full perimeter in electrically conductive contact with the bulkhead. The sheathing of each cable is treated so that the conductive shield of each cable is exposed. The cables pass through the housing with their exposed shield being within the interior of the housing. The end portions of the housing are sealed, such as by the use of deformable material. Electrically conductive material, such as shot, granules, powder, grease, liquids or the like, is used to fill the interior of the housing to form conductive paths between the shield of each cable and the housing. The material may be in the form of particulates, semi-liquid, or liquid, including conductive coatings.

Abstract: Disclosed is a method for recovering hydrocarbons from a hydrocarbon-bearing formation. A wellbore is drilled to penetrate the formation and to extend, preferably substantially horizontally, into the formation for a suitable distance. The well is completed with a slotted or perforated casing means and with dual concentric tubing strings. The tubing strings comprise an inner tubing and a surrounding larger diameter outer tubing. The inner tubing cooperates with the outer tubing to form a first annular space and the outer tubing cooperates with the casing means to form a second annular space. After the wellbore is suitably completed, a heated fluid is circulated within the casing means such that the heated fluid passes through a portion of the first annular space to heat the well and to provide a fluid flow path through both the first and second annular spaces. After the well is suitably heated, a heated fluid is injected into the formation through at least a portion of the second annular space.

Abstract: Disclosed is a method for recovering hydrocarbons from a subterranean formation. A heated fluid is injected into the formation by means of a perforated conduit which is positioned substantially horizontally through the formation to heat hydrocarbons within the formation. After a suitable heating period, injection of heat is terminated to permit fluids including formation hydrocarbons to drain from the formation into the conduit. The drained fluids within the conduit are then heated to a temperature such that at least a portion of the drained fluids are vaporized. These vaporized fluids pass from the perforated conduit and into the formation to further heat formation hydrocarbons. Subsequently, formation fluids of reduced viscosity are recovered from the formation through the perforated conduit.
