Abstract: Granules of plastics material have grains of an inert mineral such as sand coated thereon to provide a habitat for microorganisms effective in waste water treatment, the granules having a predetermined particle size range, and the grains having a predetermined particle size range and being disposed at a predetermined packing density range on the granules. The particles have an average density of approximately 1.0 g/cc such that a proportion tend to float and a proportion tend to sink in the waste water. The particles arc manufactured by contacting the granules of plastics material with a mixture of grains of the inert mineral and grains of a soluble substance such as salt, at an elevated temperature, to coat the granules with the mixture, and subsequently dissolving the soluble substance grains from the coating to provide the granules coated with the grains of inert mineral in the predetermined packing density range.

Title: Luft-st°ttet flatbeltet transportbÕnd og fremgangsmÕte for transportering av gjenstander
Inventor: MENSCH WILLIAM A
IPC: B65G15/60
Filed: 1998-12-02
Abstract: En luftunderstøttet transportør (10), særlig innrettet for å fremføre gjenstander slik som bagasje eller pakker i høy hastighet, omfatter et plenumkammer (3, 21) og en beltebærer som omfatter flere åpninger (35). Luft eller annet trykksatt fluid tilføres til plenumkammeret (3, 21) for å opprette en klaring eller luftopplagring mellom beltet (9, 37) og bæreren under beltets (9, 37) fremføring. Beltebæreren har et hovedsakelig flatt midtparti med ytterpartier (43) som er krummet eller skråstilt oppover. Føringer er montert inntil de skråstilte ytterpartier (43). Anordnet langs lengdeutstrekningen av beltet (9, 37) samt mellom undersiden (63) av hver føring (57)og de skråstilte ytre beltepartier er det anordnet langstrakte legemer. Hvert langstrakt legeme i samordning med undersiden 63 av hver føring (57) og beltebæreren gjør tjeneste som en beltekantføring (50) ved å danne en uttaking som mottar beltekanten under beltets (9, 37) fremføring. Hver slik uttaking retter luft fra beltets (9, 37) underside (39) oppover og rundt beltets (9, 37) sidekant, samt tvers over oversiden (39) av beltet (9, 37) samt ut av et spalteutløp. Denne uttaking bidrar til å opprette et trykk mot oversiden av beltet (9, 37) i nærheten av føringens (57) underside (63), slik at beltets (9, 37) eventuelle kontakt med føringens (57) underside (63) derved nedsettes til et minimum eller helt elimineres, slik at potensiell slitasje eller skade av beltet (9, 37) ved fremføring under høy hastighet unngås.

Abstract: A plant for tempering a building, including an energy storage unit formed by ground heat exchangers coupled in parallel and each including a heat insulated leg and a non-insulated leg in thermal contact with surrounding soil. The heat exchangers are included in a circulating circuit for a circulation fluid which includes a circulation pump and room temperature keeping devices. The energy storage unit has a continuously varying temperature in a depth direction from a cold end to a warm end. The flow direction in the ground heat exchangers is controlled by a reversing valve such that for a warm keeping function, circulation fluid is received from the warm end and for a cool keeping function, circulation fluid is received from the cold end. The circulation pump is controlled such that the circulation flow brings about a temperature difference between the inlet and outlet of the ground heat exchangers that is constant with a value that can be calculated with the aid of the properties of the ground and the actual components.

Abstract: Electric current is produced in an electrochemical generator having two chambers at different levels. The process involves creating a flow of a liquid electrolyte within the two chambers in series. The liquid electrolyte contains active solid particles or solid particles transporting an active material, the density of the particles is greater than that of the electrolyte, and the surface of the inner face of at least one chamber is formed by the electrolyte-side surface of an electron collector. The particles form in each chamber a sedimentation bed contiguous to the lower face of said chamber and entrained by the electrolyte. The flow passes from one chamber to the other through a conduit in such a manner that the flow lines in the vicinity of each of the edges which respectively define the upper and lower openings of the conduit are oriented substantially at right angles to the edges.

Abstract: The composite comprises diamond crystals and a substrate of polycrystalline silicon carbide or silicon nitride bonded by silicon carbide and a carbide and/or silicide of a metal which forms a silicide with silicon. A mass of diamond crystals in contact with a mass of eutectiferous silicon-rich alloy and a silicon carbide or silicon nitride ceramic substrate are disposed in a container and placed within a pressure transmitting powder medium. Pressure is applied to the powder medium resulting in substantially isostatic pressure being applied to the container and its contents sufficient to dimensionally stabilize the container and its contents. The resulting shaped substantially isostatic system of powder-enveloped container is hot-pressed whereby fluid eutectiferous silicon-rich alloy is produced and infiltrated through the interstices between the diamond crystals and contacts the contacting face of the substrate sufficiently producing, upon cooling, an adherently bonded integral composite. In a modification, the use of a container is avoided by pressing a cavity in the pressure transmitting powder medium, placing the silicon-rich alloy, diamond crystals and silicon carbide or silicon nitride substrate in the cavity, covering the cavity with further powder medium, then applying isostatic pressure and hot pressing.

Abstract: A method of controlling a heating furnace for steel ingots, particularly a soaking pit for steel ingots, which is charged with a basic fuel quantity for heating the ingots to rolling temperature. The surface temperature of the ingots and thermal data of the furnace are measured and heat balances are established. From the resulting furnace balance temperatures, together with the surface temperature of the ingots, an estimated value for the center temperature of the ingots is determined in an estimating device. The estimated ingot center temperature and the ingot surface temperature as actual temperatures are compared with predetermined ingot core and surface temperatures as nominal temperatures. The resulting difference is used to correct the basic fuel quantity fed to the furnace. The surface temperature of each individual ingot in a furnace may be measured. The correction of the basic fuel quantity may be started after an empirically determined time interval of ingot heating in the furnace, and may be 1/4 to 1/3 of the total required pit time, which is the time between charging and drawing of ingots from the pit. During the pit time, ingots are heated in the soaking pit.
