Abstract: Abstract of the Disclosure A protective coating composition and process is described for simultaneously sealing and priming the anodic coating applied to aluminum and alloys thereof without the need for elevated temperatures during a subsequent curing step. The composition comprises a colloidal, water-borne polyurethane resin which is an aromatic, aliphatic or alicyclic copolymer. The com-position is curable at ambient temperatures but may include a cross-linking agent as well as a thermosetting catalyst,  The process comprises the steps of anodizing the component to be coated, applying the coating com-position at elevated temperatures to thereby simultan-eously seal and prime the component and curing the seal-ed and primed component at ambient temperatures. If cross-linking agents are employed then elevated cure temperatures are utilized.

Abstract: "Solid-State Image Pickup Apparatus"                         ABSTRACT      An incident optical image is split by a single semi-transparent mirror into first and second optical images of like wavelength components, one of these images being reflected upon the mirror so that they are reversely oriented to each other with respect to at least one of horizontal and vertical lines.  The split images are made to be incident on two image sensors to generate charges which are transferred in a vertical direction to horizontal scan charge transfer sections for subsequent transfer to respective output terminals.  The horizontal scan charge transfer section of each sensor is driven by sequentially clocked pulses in a horizontal scan direction opposite to the scan direction of the other sensor so that images which will be reconstructed by signals from the image sensors are coincident in orientation to each other.

Abstract: PLURAL COMMUNICATION CHANNEL   PROTOCOL SUPPORT SYSTEMS Abstract Protocol support and message buffering circuitry is used to transmit call status, control and terminal management information bidirectionally over associated conductor pairs as signalling messages between a system processor and a phone and/or terminal served by the system and connected to each conductor pair.  This information is transmitted serially in a modified HDLC format as a one bit signalling field of a multiplexed data frame.  At each teransmitting end, the message information is converted from a parallel to a serial format, transmitting serially as the signalling bit of successive frames, and reconverted to parallel at the receiving end.         Ports terminate the system end of the conductor pairs and are mounted four to the board.  Each board contains circuitry, such as registers and the like, common to the signalling message protocol support and message buffering circuitry of all four ports.  The processor means, reads and writes these common registers via the I/O bus to determine the status of each port and to exchange messages with the remote phones and terminals served by the ports.  Multiplexing is used on the signalling message so that the system processor can direct a message individually to each of the plurality of station devices connected to the station end of each line. Protocol support is carried through to the processor to support the error detecting capabilities of the protocol.

Abstract: ABSTRACT         A silica-titania cogel is produced in a two-step process wherein in the first step an alkyl polysilicate and/or a tetraalkyl silicate is partially hydrolyzed in an alkaline organic solvent using insufficient water to complete hydrolysis and thereafter a tetraalkyl titanate and an excess of water are added to complete the hydrolysis. The resulting product is as good or better than silica-titania cogels made by expensive prior art techniques and offers the advantage of not requiring washing step to remove alkali metal ions and thus also does not require an azeotrope drying step to remove water.

Abstract: TITLE OF THE INVENTION          "Polygranular carbon member and method of producing it"          ABSTRACT OF THE DISCLOSURE          The invention relates to a polygranular carbon member of granular or, respectively, pulerulant and/or fibrous carbon particles as filler materials and of a binder, which has been subjected to a thermal treat-ment for consolidation of the binder, as well as to a method of producing such a carbon member. That kind of a carbon member is to be dimensionally stable, self-supporting and rigid also in the case of extremely low wall thicknesses and relatively large surface area dimensions, and it is to be able to be produced economically. For this purpose, it is suggested according to the invention that carbon materials, such as coke, carbon black, carbon fibers, natural or synthetic graphite and the mixtures thereof, are incorporated as filler material, and that the carbon member has at first, prior to the thermal treatment and under the influence of shearing forces, been shaped from a plastic carbon composition (mass) with a carbonaceous, cokable binder content of from 50 to 150 % by weight, based on the filler material, into a thin, plate-shaped member and through the subsequent thermal treatment into a sheat-like article of a specific configuration.

Abstract: ARTICLE OR SEED COUNTER                   Abstract of the Disclosure A sensor for counting articles, such as seeds, moving through a conduit includes an array of infrared LEDs generating a uniform diffuse beam of radiation which entirely illuminates a cross sectional volume of the conduit.  The beam is detected by a planar photo diode which extends across the opposite side of the conduit.  A pair of mirrors extend along opposite sides of the conduit between the array and the photo diodes.  Slits narrow the beam and limit the amount of radiation which can impinge upon the photo diode.  The signal from the photo diode is integrated by a signal processing unit so that the sensor can count a plurality of seeds in a group of seeds which simultaneously pass through the beam.  The signal processing unit automatically compensates for changes in the steady state photo-diode output and for changes in seed size.
