Abstract: OFFSET, SERIES CONNECTED CURRENT LIMITING FUSE      AND EXPULSION FUSEHOLDER ASSEMBLY      FOR OPENGATE CUTOUT                 ABSTRACT OF THE DISCLOSURE           A combination dropout assembly adapted for use with protective cutouts in an electrical distribution system com-prises a current limiting fuse electrically connected in series with an expulsion-type fuse, and mechanically coupled in skewed relation to the latter, whereby the assembly provides reliable full range fault current protection yet is sufficiently com-pact in length to matingly span the gate between conductive terminals of conventional 15 KV class opengate cutouts found in many existing electrical distribution systems.  Overload and low to medium fault current protection is provided by the expulsion fuse, while high range fault currents are cleared by operation of the current limiting fuse.  The oblique arrangement of the fuses relative to one another permits venting from either end of the expulsion fuse without direct-ing potentially detrimental gases toward the current limiting fuse, and further allows the combination of various sizes of current limiting fuses and expulsion fuses in the make-up of the dropout assembly such that protection characteristics of the latter may be tailored to preserve coordination of a particular distribution system.

Abstract: CRYPTOGRAPHIC COMMUNICATION SECURITY FOR MULTIPLE DOMAIN NETWORKS  ABSTRACT       A communication security system for data transmissions between different domains of a multiple domain communication network where each domain includes a host system and its associated resources of programs and communication terminals.  The host systems and communication terminals include data security devices each having a master key which permits a variety of cryptographic operations to be performed.  When a host system in one domain wishes to communicate with a host system in another domain, a common session key is established at both host systems to permit cryptographic operations to be performed.  This is accomplished by using a mutually agreed upon cross-domain key known by both host systems and does not require each host system to reveal its master key to the other host system.  The cross domain key is enciphered under a key encrypting key designated as the sending cross domain key at the sending host system and under a different key encrypting key designated as the receiving cross domain key at the receiving host system. The sending host system creates an enciphered session key and together with the sending cross-domain key performs a transformation function to reencipher the session key under the sending cross domain key for transmission to the receiving host system.  At the receiving host system, the receiving host system using the receiving cross-domain key and the received session key, performs a transformation function to reencipher the received session key from encipherment under the sending cross domain key to encipher-ment under the receiving host system master key.  With the common session key now available in usable form at both host systems, a communication session is established and cryptographic operations can proceed  between the two host systems.

Abstract: ABSTRACT OF THE DISCLOSURE         A projection type television set having a main body, a projecting tube accommodated by the main body, a screen attach-ed to said main body and a mirror box pivotally mounted on the main body for free rotary movement around an axis between a clos-ed position and an opened position, the mirror box including a mirror which is adapted, when the mirror box is in the opened position, to reflect the light coming from the projecting tube and project the same onto the screen so as to make a display of an image on the screen.  The mirror box is connected to the main body through at least one control rod which has a tubular body, a spring seat movably received by the tubular body and a pair of coiled springs disposed at respective sides of the spring seat.  As the mirror box is swung from the closed position toward the opened position, one of the coiled springs is released to exert a force for assisting the manual opening force, while the other coiled spring is compressed to prevent an abrupt declina-tion of the heavy mirror box attributable to the weight of the same.  Similarly, the other coiled spring is released while one of the coiled springs is compressed, when the mirror box is moved from the opened position to the closed position, so as to assist the manual force and to prevent the abrupt declination, respectively.

Abstract: ABSTRACT OF DISCLOSURE            A deflection wedge is positioned in a long horizontal drill hole by securing it with a shear pin to an extension on a drill string.  The extension is turned independently of the drill string to enable a droparm mechanism to actuate a trigger which stops rotation at a predetermined orientation.  Rotation is effected by means of a rifle bar mechanism.  In one case the rifle bar presses against the bottom of the hole to cause rotation and the trigger declutches the rifle nut when the droparm drops.  In another case hydraulic pressure pushes a rifle bar from the drill string into a nut on the extension and the trigger causes a valve to close which causes water lock and thus prevents further movement of the piston and rotation of the extension.
