Abstract: ABSTRACT OF THE DISCLOSURE   A flexible convoluted hose construction is provided herein.  The flexible convoluted hose comprises an elongated, single-piece, elastomeric strip having a base and first and second connecting members extending in the same direction from the base, with the first connecting member exten-ding from a central part of the base to define a lateral extension of the base outwardly of the first connecting member.  The second connecting member extends from an end portion of the base.  The strip is disposed in a helical pattern, with the first and second connecting members connected to define the hose construction having a plurality of helical turns defin-ing alternating crests and troughs.  The lateral extension in each helical turn of the strip slidingly engages the base beneath the second connecting means in underlapping relation to provide the hose construction with a substantially smooth inside surface, the smooth inside surface being pro-vided even with the hose construction extending in a curved path due to the lateral extension slidably engaging the base portion and bridging any gap which would otherwise be produced in the inside surface along an outer radius of the curved path.  The hose thus is substantially free of gaps or irregularities capable of trapping materials flowing through the hose con-struction.

Abstract: ABSTRACT OF THE DISCLOSURE         A cavity of predetermined size is formed in a compressed pressure-transmitting powder medium. A mass of diamond crystals is placed in contact with a mass of elemental silicon, and both masses are disposed within the cavity. Additional pressure-transmitting powder is placed over the cavity, producing a powder-enveloped cavity.  Pressure is applied to the powder medium, resulting in substantially isostatic pressure being applied to the cavity and its contents sufficient to dimensionally stabilise the cavity and its contents. The resulting shaped substantially isostatic system of powder-enveloped diamond and silicon is hot-pressed to liquefy the silicon and cause it to infiltrate the interstices between the diamond crystals producing, upon cooling, an adherently-bonded integral body. The resulting polycrystalline diamond body consists of a mass of diamond crystals adherently bonded to each other by a silicon atom-containing bonding medium consisting essentially of silicon carbide and elemental silicon.  The diamond crystals range in size from about 1 micron ? about 1000 microns. The density of the diamond crystals ranges from about 65% by volume to about but less than 80% by volume of the body. The bonding medium is distributed substantially uniformly through-out the body. At least about 85% by volume and preferably 100% by volume of the portion of the bonding medium in direct contact with the surfaces of the diamond crystals is silicon carbide. The diamond body is substantially pore-free, and is useful as an abrasive, cutting tool, nozzle or other wear-resistant part.

Abstract: ABSTRACT OF THE DISCLOSURE In a system which includes a common bus to which a plurality of units are connected for the transfer of informa-tion, such as a data processing system, information may be transferred by the highest priority unit during an asynchronously generated bus transfer cycle. Logic is provided for enabling a first unit, such as a central processor, to make a multiple fetch request of a second unit, such as a memory, during a first transfer cycle.  The multiple fetch request requests the second unit to transfer multiple parts of data to the first unit during multiple further transfer cycles, wherein one part of data is transferred in each further transfer cycle.  Logic is provided in the second unit to enable the second unit to indicate to the first unit, except during the last further transfer cycle, that each further transfer cycle will be followed by another further transfer cycle.  Logic is provided in the first unit to enable the first unit to accept less parts of data than originally requested in the multiple fetch request.  This permits the first unit to make multiple fetch requests of other units on the bus without regard to whether the other units are capable of performing multiple fetch operations and eliminates the need for abnormal condition recovery logic in the second unit. Logic is also provided to permit the first unit to utilize each part of data as it is received by the first unit without re-quiring the first unit to wait for the last transfer cycle before using any of the received parts of data.
