Title: Synthesis gas from petroleum coke
IPC: C10J3/46
Filed: 1971-07-13
Abstract: Synthesis gas is produced by contacting a stream of an aqs. slurry contg. 25-75 wt.% petroleum coke of particle size 12-325 mesh with a stream of an O2-rich gas in an unpacked, non-catalytic refractory-lined synthesis gas generator to produce a dispersion of the slurry which is reacted with the gas at 1800-3500 degrees F and 100-3000 psig. The amounts of the feed streams are controlled to give a product synthesis gas stream having entrained therein unconverted coke contg. at least 8 wt.% of the carbon originally present in the coke feedstream. The unconverted coke entrained in the product gas stream retains sufficient of the heavy metal contaminants present in the coke feed to enable the life of the refractory lining to be extended by thousands of hours.

Title: Scraped surface heat exchanger - for solidifying cocoa butter or paraffin wax or heating liq. contg. solids
IPC: C11B15/00
Filed: 1975-06-05
Abstract: A method transfers heat indirectly to fats or similar prods. in order to solidify them or heat them. The hot liq. prod. is fed to a narrow space, filled with liq., between two surfaces which move relative to one another. The prod. is fed by a pump or a screw. >=1 of the surface is heated or cooled. The temp. and press. in the space keep the prod. liq. As it leaves the space and enters a form at normal pressure it solidifies. Method is used to cool and solidify cocoa butter or paraffin or to sterilise liqs. contg. solids. If the prods. are allowed to solidify in forms several hours are needed for cooling. The method greatly reduces the cooling time.

Title: Tubular instrument with expanding element for insertion into uterus - for introducing fluids into the fallopian tubes, used esp. for sterilisation
IPC: A61M31/00
Filed: 1979-03-28
Abstract: The catheter type instrument, which enables a treatment fluid to be introduced into the fallopian tubes, consists of a straight tubular element with, at its outer end an expanding element, pref. of rubber, which, upon the introduction of a hydraulic fluid, expands and fills the hollow of the uterus. The outer end of the instrument has openings through which the treating fluid is introduced into the uterus. Since the hollow of the uterus itself is already filled with the expanding element, the treating fluid can only flow into the fallopian tubes of the mammal. The instrument is used particularly for sterilisation purposes. Since the body of the instrument is one tube, there is minimal risk of damage to the internal organs of the mammal during insertion or expansion of the expanding element.

IPC: C04B35/65
Filed: 1987-09-15
Abstract: There is disclosed a method of producing a self-supporting ceramic composite body having therein at least one cavity which inversely replicates the geometry of an expendable pattern (6). The method includes the steps of surrounding the expendable pattern (6) with a filler material (4) to thereby form a filled cavity within the filler material (4). The expendable pattern (6) is chemically or physically removed from the filler material (4) and a quantity of a parent metal is put into the cavity. The parent metal is heated to a temperature above its melting point and an oxidation reaction process begins whereby the oxidation reaction product infiltrates and embeds the surrounding filler material (4). Excess filler material and/or excess parent metal are removed, thus resulting in a self-supporting ceramic composite body having a cavity in the shape of the expendable pattern (6).

Abstract: In a communications system having transmissions containing certain information-of-interest (147, 149) at predetermined intervals in the transmission, there is provided a method for isolating and processing that information-of-interest. The method is characterized by sensing the start of a transmission (141) and isolating for processing as the information-of-interest, the information received about instant(s) predeterminally removed in time (145) from the sensed start of transmission (141). Thus, the information-of-interest is isolated principally on the basis of elapsed time. The method for isolating and processing that information-of-interest is further characterized by sensing (249) the start of a transmission from the received signal power of the transmission exceeding a predetermined threshold (259); AGCing the transmission (233) and attenuating the AGC'd transmission from a maximum level to a desired level before the information-of-interest is expected to arrive; isolating for processing as the information-of-interest, the information received about instant(s) predeterminally removed in time from the sensed start of transmission, by timing (263) the expected interval between the instant that the start of the transmission is sensed and the predetermined instant that the information-in-interest should arrive (whereby the information-of-interest is isolated principally on the basis of elapsed time); tagging the information (247) isolated about that instant for processing; and beginning processing (275) with information just preceeding the isolated information (whereby the reliability of the information detection is enhanced by one-to-several bits). <IMAGE>

Abstract: Disclosed is a method of making graft copolymers of olefin polymers by contacting a particulate olefin polymer with a free radical polymerization initiator, e.g., a peroxide, and a vinyl monomer at about from 60 DEG  to 125 DEG  C, while controlling the monomer addition rate so that it does not exceed about 4.5 pph/min, and most preferably does not exceed about 3.0 pph/min, at any monomer feed level. To prevent polymer degradation, a non-oxidizing environment is maintained throughout the process, and residual free radicals are deactivated, and unreacted initiator is decomposed, before the graft copolymer is exposed to air.
