Abstract: VIDEO DISC HANDLING SYSTEM FOR A VIDEO DISC PLAYER      Abstract of the Disclosure A protective cover, subject to a removable oc-cupancy by a video disc, is inserted into a video disc player.  During the insertion of an occupied cover into the player, an appropriately designed platform leads it to a fully inserted position such that a clamping device built into the player protrudes into the cover.  The user then removes the cover allowing the video disc to remain in the player resting on the platform.  When the player lid is closed, the platform is lowered to effect a transfer of the video disc resting thereon to the player turntable.          Upon playback, the lid is raised to cause the video disc to rise with the platform.  An empty cover is then in-serted to return the video disc back into the cover.  The subsequent withdrawal of the cover removes the enclosed video disc.

Abstract: RESTRAINING STRUCTURE FOR USE IN CONTAINERS     Abstract Of The Disclosure A surface for mounting an item in a container is provided with clamping members which restrain the item against the surface. Each clamping member includes a frustum-shaped lug having a gripping portion on its peri-phery, and also has a resilient member for mounting the lug to the mounting surface so that at least a portion of the lug is movable in a generally perpendicular direc-tion with respect to the mounting surface.  In use, a plurality of clamping members are secured to the mounting surface so that their gripping portions engage the peri-meter of the item when it is received on the mounting surface.  With the item in this position, the clamping members restrain it against the mounting surface.     .

Abstract: ABSTRACT OF THE DISCLOSURE    An air control valve for a vehicle emissions control system has an inlet connected to the output of the vehicle air pump, a first outlet connected to exhaust injection passages in cylinder head, and a second outlet connected downstream into the exhaust manifold. A vacuum actuated valve element is responsive to engine manifold vacuum to divert the output of the air pump from the downstream injection point to the upstream injection point during cold engine operation. However, the air supply from the air pump is diverted from the upstream injection point to the downstream injection point for a few seconds when a sudden increase in manifold vacuum occurs, such as during engine deceleration when the engine is cold. After the engine warms up, the air supply from the air pump is continuously communicated to the downstream injection point.

Abstract: A B S T R A C T This invention relates to a method and to an arrangement for selectively transmitting predetermined characters or graphic patterns.  In a transmission of graphic patterns, data words are assigned to graphic patterns which have the same format as the data words and are transmitted instead of the data words assigned to the predetermined characters. In the receiving station the code words are transformed into binary bit sequences and fed to a mosaic printing head instead of the bit sequences emitted by a character generator in the receiving station.  A switch-over character is transmitted to change between data word transmission and graphic word transmission.  Only slight modifications are required in the transmitting and receiving stations to enable the transmission of graphic patterns in addition to predetermined data characters.

The liquid is thereafter volatilized with the resulting dry ultrafiltration membrane being essentially crack-free and having desirable mechanical and chemical stability.  The support may be pretreated with a volatile liquid, such as acetone, prior to the applying of the coating to the support.  Alternately, the coating material can be dispersed in a volatile liquid, such as methanol, to form a coating suspension that is applied to the support.  The coating material, preferably zirconia, will have a particle size within the range of from about 5 mu to about 10 u, with the coating having a thickness of up to about 20 u.  The support, such as a porous carbon tube, will have a pore volume of about 5-60% and a pore size of about 5 mu - 40 u. Stability is enhanced by firing the membrane at 25°C-1500°C, preferably at about 400°C-600°C.     S P F C I F I C A T I O N:

Abstract: SELECTIVE MULTIPLE ELECTRODE WASTE WATER TREATING SYSTEM     Abstract Of The Disclosure A plurality of individual treaters, each containing a pair of oppositely charged electrodes, are arranged circularly around a centrally disposed tank into which all of the treaters empty.  A common supply manifold for all of the treaters brings waste water or other liquids into the system for treatment by any selected one of the treaters upon opening a control valve associated with such selected treater and closing control valves associated with the remaining treaters. Each treater contains an electrode that is con-structed from a material differing from that of electrodes in the remaining treaters so that a particular treater may be selected for use based upon the predicted reaction of the material from which its electrode is made with the particular constituents of the waste liquid being treated. The central tank into which all treaters empty includes a pair of oppositely charged electrodes of its own to expose the once treated liquid to yet a second electric field, and there is a special structure associated with the lowermost discharge end of the electrode pair within the tank which is so arranged and configured that it reduces turbulence adjacent the floor of the tank such as to encourage settling out of floc produced by the treating process.

Abstract: ABSTRACT           A damper assembly for an air passage.  A damper assembly includes a disk element associated with a circular orifice of an air passage, and an actuator having an associated drive element. The disk is coupled to the drive element and a fixed reference point by a linkage so that as the actuator drive element is displaced from a first limit position to a second limit position, the disk moves between a sealing position and an open position. In the sealing position, the disk perimeter is flush against the perimeter of the orifice establishing an air-tight seal between the disk and the perimeter of the orifice.  In an open position, the disk is displaced from the orifice perimeter and forms an angle with a plane defined by the orifice perimeter.  An array of damper assemblies may be configured with a controller for selectively controlling the position of each actuator between the respective limit positions.

Abstract: (Case No. 7033) ABSTRACT OF THE DISCLOSURE A frequency modulated track circuit arrangement in which a transmitter supplies an FSK signal to the rails, with side frequencies deviating by equal amounts from a central carrier frequency and alternating at a preselected modulation rate.   The receiver apparatus includes first and second verification circuit networks coupled to the rails through a band pass filter network which passes only the correct side band fre-quencies based on the central frequency of the transmitter.          The first verification network demodulates only the correct side frequencies and decodes the resulting signal to produce an output only if the modulation rate is correct.  The second verification network comprises an amplifier with a predeter-mined threshold level based on the known attenuation of the transmitted signal by the track circuit and produces an output only if the track signal equals or exceeds this threshold level.  The two network outputs, only if both are present, activate an AND gate which supplies an output signal to a delay circuit element which energizes the associated track relay only if the duration of the verification outputs exceeds the preset delay period which eliminates very short noise pulses possibly having true characteristics.
