Abstract: ABSTRACT OF THE DISCLOSURE          The invention relates to display devices having a memory making it possible to display information supplied by electric signals and to maintain this dis-play when the signals have disappeared.  In a smectic liquid crystal display cell it comprises providing means making it possible to move apart the two plates enclos-ing the liquid crystal layer so as to make the latter diffusive throughout.  Parts of this crystal are then made transparent by applying thereto a reorientation electric field by means of a set of electrodes.  It is intended for use more particularly in telephone exchanges having a device for the display of digital data transmitted on a telephone line.

Title: Release coupling

Granted: 1984-05-08
Abstract: ABSTRACT      A high pressure coupling for releasably coupling high pressure tubular elements in sealed relationship, the coupling comprising a first tubular member having a socket formation, a second tubular member having a spigot forma-tion sealingly engaged with the socket formation in mating relationship therewith, one member having an annular recess and the other member having a radially directed annular bearing surface to cooperate with a locking sleeve, and a radially deformable locking sleeve posi-tioned in the annular recess, the locking sleeve being located against radial deformation out of the recess by the bearing surface engaging with the bearing surface of the locking sleeve.  The coupling further includes bias means operative between the tubular members to provide a predetermined bias force to restrain axial separation of the mated formations.  The tubular members of the coupling are axially separable upon application of an axial separa-tion force in excess of the predetermined bias force of the bias means for the bearing surface to disengage from the locking sleeve, and for the locking sleeve to be radially deformed out of the annular recess to release the member having the recess for the spigot formation to separate from the socket formation and permit automatic uncoupling of the coupling.  The tubular members are further shaped to define an annular pressure balancing chamber which is in communication with the coupling bore and which is further defined by axially spaced radially extending pressure flanges which are associated with the members for pressure within the balancing chamber to act on the flanges for urging the members into mating engage-ment and at least partially balance the axial separation force generated by pressure in the coupling during use.

Abstract: ABSTRACT OF THE DISCLOSURE         A system for providing television, information and data signals via a transmission network to selected subscribers, to groups of subscribers, or to all subscribers connected in common to the transmission network.  An address code signal is stored at the subscriber station, and an option code signal is sent to the particular subscriber station from a head end of the network.  Signals having an address portion designative of the option code or address code signal are sent down the transmission line and are translated by the subscriber station in the event the address matches the first and second code signal.  Thus signals can be sent to all subscribers which have option codes designated by the address of data packets transmitted down the transmission line.  These groups of subscribers can be all subscribers, individual smaller groups of subscribers, or a group consisting of even a single subscriber.  The option codes can be changed from the head end at will.  Consequently data can be transmitted to various subscribers designated form the head end under its complete control.  The data can be control signals for controlling the unscrambling of pay-TV signals, software for operating a mircocomputer peripheral, data to enable operation of a local television channel converter to facilitate selection of particular channels depending on service paid for, etc.  Since the option codes can be changed from the head end, cheating of the system is inhibited and the requirement to send service personnel to each subscriber to enable the acquisition of changed services is avoided.

Abstract: APPARTUS FOR SEPARATING FOREIGN MATTER    FROM A GAS WITH A HEAT EXCHANGER     ABSTRACT OF DISCLOSURE:     A gas cleaning and heat transfer apparatus is used with a hood assembly associated with cooking equipment to separate foreign matter from gas moving through the hood assembly and transferring heat from the gas to a fluid.  The apparatus has a plurality of gas cleaning units that concurrently operate to separate foreign matter from the gas and reduces the tem-perature of the gas.  Each cleaning unit has a heat conducting wall surrounding a tubular passage for carrying gas and foreign matter.  A plurality of helical elements located in the passage are positioned in angular relationship relative to each other so that the gas moving through the passage is divided into separate helical gas streams.  A jacket having a fluid accom-modating chamber surrounds the cylindrical wall.  Heat from the gas in the passage is transferred through the wall to the fluid.  The foreign matter is separated from the gas as it moves in the spiral path through the passage by the combined mechanisms of centrifugal force, adhesion, condensation, and impaction.  The surrounding fluid cools the gas adjacent the inside of the wall causing condensation of vapors carried by the gas on the wall to facilitate the collection of foreign matter on the wall.  The collected foreign matter flowing along the wall is carried by the moving gas to an annular collecting member located adjacent the exit end of the wall.          Cleaned gas flows through the annular collecting member to the environment outside the apparatus.
