Abstract: ABSTRACT OF THE DISCLOSURE         A tire (10) produced via a molding or casting process in a manner such that each of its bead areas (16) includes an annular slot (42) whereby the slots permit the insertion of an inextensible annular reinforcement element (40) into each of the bead area slots (42) after the molding or casting process.  Slots (42) are preferably produced by the addition of annular collars (64) to either the outer member (50) or core member (60) of an improved molding or casting die (48).  The improved molding or casting process includes a step of forming a circumferential slot (42) in each tire bead area (16), with these slots (42) permitting the addition of an inextensible annular reinforcement element (40) into each bead area (16) after the molding or casting process.

Abstract: AUTO-ZEROING OPERATIONAL AMPLIFIER CIRCUIT                     ABSTRACT    A temperature stable bandgap voltage reference source utilizing bipolar transistors 12 and 14 biased at different emitter current densities is provided.  Switched capacitors 28 and 34 are used to input the Vbe and the .DELTA.Vbe of the transistors 12 and 14 (PTC and NTC voltages, respec-tively,) into an operational amplifier 42 to provide a reference voltage VREF Proportional to the sum of  he PTC and NTC voltages. Proper selection of the ratio of the switched capacitors 28 and 34 renders the reference voltage VREF substantially independent of temperature. In a modified form of the reference source 10, the reference amplifier 22 is implemented by an auto-zeroed operational amplifier 42 which uses switched capacitor techniques and an integrated capacitor 44 to achieve the auto-zeroing function.

Abstract: ABSTRACT OF THE DISCLOSURE        A video image display apparatus, of the flat tube and multiline cathode type, includes a phosphor screen, and a predetermined number (e.g. 15) of line cathodes for emitting in-turn a predetermined number of horizontal rows of electron beams each row comprises a second predetermined number (e.g. 320) of rod-shaped electron beams which together produce one horizontal line of image on the phosphor screen.  Groups of the horizontal lines form vertically extending segments.  A vertical deflection means is provided for deflection of each of the respective rows of electron beams in the respective vertically extending segments, by means of a vertical deflection signal, e.g. a step wave having a saw-tooth wave envelope.  The envelope is adjusted so as to be expanded or compressed or changed in level, thereby eliminating any undesirable black (or light) horizontal banding on the screen due to non-uniformity of electrode construction.  A uniform raster is thereby obtainable.

Abstract: Abstract of the Disclosure : In a centrifugal separator, in particular for separating light materials, such as grass seed, from an air flow, a whirl chamber is provided between a circumferential wall of the separator casing and a radial-ly inner filter consisting of a louvred shell imparting a change of direction of about 180° to the air flow on its way from the whirl chamber to the air outlet of the casing, thereby creating within the shell a counter-rotating whirl of air and material passed through the slits together with air.           To separate such material from the air, the shell is provided with a vertically extending slot asso-ciated with an ejector rail adapted to remove the outer por-tions of the counter rotating whirl and feed them back for renewed separation in the whirl chamber of the separator casing. The slits may then be given such a size that they will not be blocked up by the material or give rise to an increased loss of pressure, as the ejector rail provides for regaining the material passed through the slits.

Abstract: ABSTRACT A radio paging receiver has circuitry for receiving and demodulating modulated carrier waves to provide demodulated paging and message signals and circuitry for detecting a specific paging signal thereby to generate an alert signal as is conventional.  In conventional paging receivers the message sig-nals received can be stored up to a maximum depending upon the size of the memory used in the receiver so that when subsequent messages are received the earliest messages are progressively erased.  The present invention provides a memory protect switch which allows the user to save any message which he has read out on his receiver and judged to be sufficiently important not to lose.  Operation of the memory protect switch causes the important message to be moved out of a first memory which is progressively erased as more messages come in to a second memory which is not subject to such erasure.

Abstract: PRODUCTION OF CORROSION AND EROSION   RESISTANT SOLID CARBON ARTICLES                 Abstract of the Disclosure Solid carbon (graphite) articles used for such purposes as parts of molten metal pumps are rendered substantially resistant to both corrosion, in the form of oxidation, and erosion created by the flow of elevated temperature fluids.          The surface of a graphite article is converted to silicon carbide to a depth of about  0.040 inch and then is treated with aluminum phosphate (AlPO4), chemically reacted with both the carbonaceous substrate and the silicon carbide overcoat, to form a non-porous, corrosion and erosion resistant stratum.  The extremely hard silicon carbide which forms the exposed surface is extremely resistant to the effects of fluid erosion, while the carbonaceous interior of the article is less susceptible to oxidation due to the fact that the pore structure of the surface has been sealed and due to the oxidation-resistant effects of the aluminum phosphate.          Tests have indicated that corrosion and erosion resistance is increased over 20 times compared with untreated graphite parts.
