Abstract: BITUMEN PRODUCTION AND SUBSTRATE STIMULATION                  (D#77,179-F) ABSTRACT OF THE DISCLOSURE         A well completion, having an injection end and a recovery end, and method for recovering heavy hydrocarbons or bitumen from a subterranean formation.  The completion includes a well liner which lies in a generally horizontal disposition within a hydrocarbon holding substrate.  Means for carrying a stream of a hot stimulating fluid from the well's injection end such that said fluid will migrate into the substrate surrounding the liner.  A fluid impervious barrier is movably positioned within the well liner between the injection end and the production end thereof, and prompts establishment of a pressure differential across the said barrier.  The barrier urges pressurized stimulating agent outwardly into the substrate, thereby creating a heated path along which the bitumen emulsion flows toward the well's lower pressure production end.  The barrier is adapted to be repositioned within the liner to adjust the bitumen flow path through the substrate.           -I-

Abstract: KEY AND LOCK MECHANISM        ABSTRACT A key/combination lock having a series of first turnable members each being constructed to be moved by turning movement of a key.  There is a series of second turnable members operatively related on a one-to-one basis with the first turnable members.  Said second turnable members are constructed to be turned by finger contact.  There is a mechanism for each pair of turnable members whereby movement of the second turnable member is imparted to the first turnable member.  Each of the first turnable members has a peripheral notch, the notches being brought into alignment with one another and into register with a lock releasing mechanism upon the two stages of movement effected by the key and the finger contact.  A cylindrical key is provided for actuating the lock and has a longitudinal keyway from which circumferential grooves extend, terminating in stop faces displaced coded circumferential distances from said keyway.  The stop faces are adapted to engage internal lugs on the first turnable members. The cylindrical member can be made of plural segments in which a stop face terminates at an end face of a segment.     The lock is preferably arranged so that a record of the identity of the user is made after the first stage of turning movement but prior to the second stage.     The lock also preferably has a case containing a key holder which cannot be released until the code wheels are in predetermined positions.      The key preferably has stop faces for turning and then axially shifting a sequencing wheel. The key also preferably has a cam face to axially move the sequencing wheel. The key also preferably has a wide circumferential groove for receiving a wide lug on the case to insure full insertion of the key prior to actuation of the internal components.

Abstract: A B S T R A C T              Direct Solenoid Operated Valve With Minimal Tolerance Accumulation A four-way directional flow control air valve having a valve spool movable to a first position.  A solenoid has a pole piece seated against the valve body adjacent one end of the valve spool. An end of the valve spool is seated against the solenoid pole piece when the valve spool is in the first position.  A pusher rod on the valve spool extends through a bore in the pole piece into engagement with a solenoid armature, whereby when the solenoid is energized, the armature moves the pusher rod and the valve spool from the first position to a second position a distance equal to the difference in length between the pole piece and the pusher rod.  The valve spool can be moved back alternatively by a return spring or a second solenoid engageable with the other end of the valve spool in the same manner as the first solenoid moves the valve spool to the second position.

Abstract: FIREPROOF  PROTECTION SYSTEM FOR     ELECTRONIC EQUIPMENT                         ABSTRACT         A fireproof cabinet system for electronic equip-ment including a wall shield with an outer metal layer that acts as a radiation shield, an inner support layer and an insulation layer.  A water supply nozzle is mounted on to of the fireproof cabinet system for providing a continuous stream of cooling water on the cabinet shield for minimizing fire damage of the shield and also providing a temperature barrier for the electronic equipment.  A forced air cooling system provides cool air from a supply located outside of the equipment room to the cabinet where the coolant air is ducted along the top and side walls of the cabinet in a sheath formed between the cabinet wall and the interior so that the coolant air in combination with the cooling water act to cool both the equipment and to remove heat caused by the external fire.  By providing an independent coolant air supply from outside the fire area leading directly into ducts in the cabinet, combined with the coolant water being applied continuously to the external wall shield, the operational condition of the equipment is maintained during the course of the external fire.
