Abstract: Process for Making Solid-State Colour image device Abstract Processes for making an electronic color imaging device comprising a planar array of charge-handling semiconductive photosensors and a multicolor filter means comprising a planar array of color filter elements superimposed in precise registration over the sensing area of the photosensors.  In general, the processes comprise the steps of:  (1) successively coating on a planar array of semiconductive photosensors a plurality of photoresponsive layers; (2) subjecting each photoresponsive layer in succession to radiation to provide an exposed area of said layer; (3) removing unexposed photoresponsive coating from each layer in succession; and, (4) dyeing exposed areas of each layer of said coating in succession to obtain a series of chromatic filter elements. Color filter elements having dimensions of approximately 6µ x 6µ may be produced by the processes.

Abstract: THERMALLY ADDRESSED LIQUID CRYSTAL DEVICE                   ABSTRACT OF DISCLOSURE           A visual display device is featured which uses a new thermal electro-optic effect to provide a dark image upon a ligher background. The display is capable of being multiplexed to a large number of rows.  The device comprises a liquid crystal material mixed with a pleochroic dye of high order parameter.  When the material experiences a rapid transition from a higher to a lower, smectic thermal phase, two different textures or light states are developed; a transparent state and a light absorbing state. The transparent state is developed by applying a sensitizing voltage to certain portions of the medium.  The pleochroic dye absorbs the light passing through the unsensitized portions of medium to provide the dark image. Heating electrodes are made diffusely reflective so as to provide a visual display that has high contrast and wide viewing angle.

Abstract: ABSTRACT OF THE DISCLOSURE           The use of N-methoxypropylmorphine, N-butylmor-pholine and N,N'-dimethylpiperazine together as a catalyst system in an activator solution to give finer, more uniform cells to polyester-based polyurethane foams is described. While each of the amine catalysts has disadvantages when used alone in an activator solution, it was surprisingly discovered that together as a catalyst system none of the disadvantages were observed in the resulting polyurethane foam.

Abstract: Abstract of the Disclosure In wrapping a wire around a pin, the turn being produced is rolled against the pin by a tool surface which rotates with the wrapping motion, so that defined and reproducible contact areas are created.  As far as the forces are concerned, the contact-making and wrapping are decoupled from each other; the tension of the wire therefore needs to be designed only still for the wrapping process proper.

Abstract: ISOLATING MOUNT FOR EXTERNAL           VIBRATION SENSITIVE SENSOR           ABSTRACT OF THE DISCLOSURE       An isolating mount provides vibration isolation for a sensor that is sensitive to external vibration about a rotational axis thereof at low frequencies, and translational vibrations in all axes at high frequencies.  The isolation mount comprises a frame surrounding the sensor, and includes a plurality of columnar or beam members which are flexible in shear and stiff in compression.  The beam members have longitudinal axes which lie in a common plane, also defined by the X--Y axes of the sensor.  Connector members to couple desired beam members between the frame and the sensor and other connector members couple other beam members from the frame to the main support structure.  The beam members flex in both the X and Y axis and also the Z axis, which is perpendicular to the common plane, but because the beam members are very stiff in compression, the resistance to any rotational movement about the Z axis is high.  The columnar members are made up of a plurality of generally parallel metal shims which are molded together with a suitable elastomeric material and wherein the shims are spaced to obtain the desired flexing in shear and stiffness in compression for the mounting.

Abstract: Abstract:    An in-line pool chlorinator 10 has a water chamber 11 holding a chlorine container with bottom openings that let out dissolved chlorine and a side wall opening that determines the wetted depth of chlorine and its dissolution rate.  Chamber 11 is molded of resin material to have a closed bottom 14 and associated water passageways 13, 15, and 16.  A through passageway 13 having a venturi 17 is located below the bottom of chamber 11 for in-line connection with a pipe communicating with the pool.  An unvalved inlet passageway 15 upstream of venturi 17 extends from through passageway 13 into the chamber bottom to admit water into chamber 11.  An unvalved outlet passageway 16 extends from a predetermined water level above the chamber bottom down to venturi 17 to draw chlorinated water back into passageway 13.  The upper region of the chlorine container is made gas-tight so that water does not rise above its uppermost open side port, and the upper region of an annular space around the chlorine container within chamber 11 is sealed to prevent air from being drawn into the chamber and entrained in the chlorinated water output.

Abstract: TOUCH STRIP INPUT FOR DISPLAY TERMINAL          Abstract of the Disclosure The screen of a display terminal has touch strips extending adjacent horizontal and vertical edges.  The touch strips have electrical outputs dependent on the position along the strips at which they are touched.  Using microprocessor control the touch strips can be made to manipulate a displayed image and control the rate or level of other terminal functions.  By selecting an appropriate programming mode the touch strips can be made to present a series of programmable or soft keys. Also the touch strips can be used to provide a menu selection, scrolling and cursor generation and movement for word processing.  The use of two touch strips requires less complex circuitry than a known transparent input overlay for the display screen.  Moreover, it is a cleaner technique resulting in reduced image attenuation and distortion.           - i -

Abstract: ENCRYPTION SYSTEM KEY DISTRIBUTION        METHOD AND APPARATUS            Abstract Encryption systems typically rely on the distribution of cipher keys between terminals for scrambling and unscrambling transmitted messages. Elaborate security precautions are necessary to protect the cipher keys since a compromise of the key could result in a compromise of the transmission.  There is disclosed a key distribution method and apparatus which uses a channel from identified terminals to a central key distribution center for the establishment, on a one-session basis, of the key which is to be used for the next session between those terminals.  The key establishing link is itself encoded using a cipher key which changes after each usage. Provision is made to verify, for each new connection, that a compromise has not priorly occurred
