Abstract: ABSTRACT      This invention comprise an improved hydraulically operated flush valve for toilet flush tanks and similar devices.  Its main components are a cylinder and piston assembly positioned with its longitudinal axis directly above and vertically aligned with the vertical axis of the outlet or flush tube of the flush tank.  The moveable piston within the fixed cylinder acts as the moving and sealing element of the flush valve.  By means of an inner valve connected to the flush tank operating lever hydraulic force is caused to lift the piston thereby opening the flush valve.  There is no direct mechanical connection between the operating arm and the flush valve, and there are no chains or hinges.  There is a positive permanent flush valve alignment and a minimum of friction. In addition, the amount of water used per flushing action can be regulated to prevent water and energy wastage.

Abstract: FORMING A TIRE BEAD ASSEMBLY             Abstract of the Disclosure A tire bead assembly of a bead core, apex and gum tie strip is made by laying the gum tie strip about a non-inflatable annular member of triangular cross-section and across the slant surface of the member.  The apex is wrapped then about the tie strip and about the slant surface of an annular inflatable bag.  After the core is pressed coaxially on the tie strip so as to indent the member and thus preform the tie strip, the bag is inflated to turn the apex and underlying the strip about the core and against an annular forming member to shape the assembly suitably for the tire carcass in which it is to be inserted. A bladder is then inflated to wrap the tie strip on the second side of the core and apex.  The member bridges the gap between the adjacent edges of the bag and the bladder. An apparatus for carrying out the steps is also described. The resulting bead assembly is tightly cohered and free of wrinkles and air pockets.

Abstract: A sealing ring for a rotary shaft is disclosed. The sealing ring has a planar frusto-conical configuration and is received in an obliquely slanted groove provided in either the rotary shaft or the bearing surface surrounding the shaft.  The use of an obliquely slanted groove causes seal contact over a wide area on the rotary shaft reducing heat buildup, while the frusto-conical configuration insures that the lips of the seal are in firm continuous circumferential contact with the shaft. Oblique mounting of the sealing ring also causes axial flow of the fluid being sealed and the formation of a fluid annulus adjacent the seal and on the pressure Side thereof.  Selective positioning of a plurality of obliquely mounted sealing rings results in the formation of complementary annuli and the axial flow of fluid between adjacent sealing rings.

Abstract: ABSTRACT       A new and improved rotating cyclone centrifuge apparatus having an accelerator (A) which receives a liquid feed having solid particles to be separated there-from in an axial direction and discharges it radially outwardly in a helical flow through diametrically opposite chokes (40b) into a separation chamber (10c) whose diameter substantially coincides with the outer extremities of the chokes, whereby the fluid flow is first brought up to the velocity of the rotating apparatus and is further accelerated in excess of the velocity of the rotating apparatus as the fluid enters the separation chamber without plugging of entranceways or of the chokes by the solids in the liquid feed.  The liquid feed is precisely separated into a heavy phase which has the heavier particles and a light phase which has the bulk of the liquid and lighter particles, both of which are discharged from the same end of the separation chamber, and opposite from the feed inlet end.  Means (42) is provided for stabilizing an air core for the light phase discharge, and also means (30, 33) is provided to readily adjust the split between the light and heavy phases dis-charged from the apparatus.

Abstract: ABSTRACT OF THE DISCLOSURE      The invention relates to a process for improving the degree of graphitization of carbon black produced by subjecting hydrocarbons which are liquid or gaseous under normal conditions to a thermal conversion reaction in the presence of oxygen or an oxygen-containing gas and steam, if desired, at temperatures of 1200 to 2000° C and pressures of 1 to 80 bars. To this end, the carbon black is conveyed downwardly in a quasi-fluid state, within 1 to 5 hours through a sojourn zone in upright position, the sojourn zone being maintained at a temperature of at least 1200° C.      The invention also relates to an apparatus for carrying out this process, the apparatus comprising a graphite tube; a steel container concentrically surrounding the graphite tube; a feed pipe penetrating into the interior of the graphite tube; a water-cooled discharge means; and a nitrogen feed inlet arranged below the lower end of the graphite tube; the space left between the graphite tube and steel container being occupied by insulating material.

Abstract: ABSTRACT OF THE DISCLOSURE A cache unit includes a cache store organized into a number of levels to provide a fast access to instruc-tions and data words.  Directory circuits, associated with the cache store, contain address information identi-fying those instructions and data words stored in the cache store.  The cache unit has at least one instruction register for storing address and level signals for specifying the location of the next instruction to be fetched and transferred to the processing unit.  Replace-ment circuits are included which, during normal operation, assign cache locations sequentially for replacing old information with new information.  The cache unit further includes apparatus operative in response to a first pre-determined type of command specifying the fetching of data words to set an indicator flag to a predetermined state.  The apparatus conditions the replacement circuits in response to each subsequent predetermined type of command to bypass storage of the subsequently fetched data words when the indicator flag is in the predeter-mined state preventing the replacement of extensive numbers of data and instruction words already stored in cache during the execution of the instruction.

Abstract: THREE DECISION THRESHOLDING MODE SWITCH      AND METHOD FOR MODE SELECTION              Abstract of the Disclosure A method for three decision mode selection of a thresholding algorithm is disclosed as is a thresholding mode switch having a three decision mode determining capability that is particularly useful for facsimile-copier devices in making printed copies of mixed format documents.  The thresholding mode switch uses a reflectance difference algorithm for switching between a gray-scale thresholding algorithm and black-white thresholding algorithm to enhance the quality of prints made of mixed format documents presented for copying.          A gradient constant is established for each picture element (pel) of the document then presented for copying and a determination is made at the thresholding mode switch as to which range, of three predetermined ranges, the gradient constant falls within, with this determination being then used to control the thresholding algorithm utilized in making that portion of the copy relating to that particular pel then being copied.
