Title: Process for the separation of nitrotoluene isomers
IPC: C07C201/16
Filed: 1981-03-19
Granted: 1985-01-03
Abstract: An adsorptive separation process for separating ortho- and/or para- nitrotoluene from a feed mixture comprising the isomer to be separated and at least one isomeric nitrotoluene, comprises contacting the feed mixture with an adsorbent comprising a type X or type Y zeolite, containing at exchangeable cationic sites cations rendering the zeolite selective towards the isomer(s) to be separated, thereby selectively adsorbing said isomer(s) to the substantial exclusion of the remaining isomer(s) and thereafter recovering the selectively adsorbed isomer(s). A desorption step may be used to desorb the adsorbed isomer(s). For the separation of the ortho-isomer the cations are chromium on type X and calcium on type Y. For the separation of the para- isomer the cations are potassium, zinc, nickel, barium, calcium, cobalt, strontium, copper and/or magnesium on type X and cesium, potassium (with or without barium), sodium, iron or cobalt on type Y. For the separations of a mixture of the ortho- and para-isomers the cations are sodium, nickel, barium, copper, magnesium, calcium, cobalt and/or strontium on type X and calcium, sodium, iron, cobalt and or potassium (with or without barium) on type Y.

Title: Process for preparing animal feed supplement from ortophosphate waste
Inventor: BENDER FREDERIC GRANT
IPC: A23K1/175
Filed: 1993-10-26
Abstract: Phosphate is recovered from waste. Trialkali metal orthophosphate used to reduce, remove or retard bacterial contamination during raw meat slaughter including poultry, fish and shellfish and red meat evisceration is recovered from an aqueous waste and recycled as a food additive for animal feed. The waste water containing the phosphate can be collected and mixed with offal during processing of the offal or may be concentrated and blended with the offal as feed for animals or may be reacted with an alkaline earth metal salt and concentrated and used as a calcium and phosphate supplement for animal feed. Trisodium orthophosphate is reacted with calcium chloride and the resulting precipitate removed from the aqueous stream by filtration or centrifugation or other means for separation. The precipitate is then added to offal during processing for animal feed or dried sterilized and sold as an animal feed mineral supplement.

Title: Support device for a load-bearing roofing tile
Inventor: HOFMANN KARL-HEINZ
IPC: E04D13/12
Filed: 1996-03-04
Abstract: The invention concerns a support device (10) for a load-bearing roofing tile (12) which is disposed in a first row (14) and rests on a first roof batten (16) in the region of its ridge-side end section. The support device (10) can be laid in the ridge-eaves direction and placed, at the ridge end, on a roof batten and, at the eaves end, on at least one covered roofing tile. In order to provide a support device which, even in the case of a double plain tile roof, introduces the force exerted by the load-bearing roofing tile into the roof substructure such that the roofing tiles covered directly by the load-bearing roofing tile and the roofing tiles covered by these roofing tiles are exposed to the risk of breakage, the invention proposes constructing the support device (10) as a carrier which can be fitted into the second row (22) of roofing tiles (24, 26) which is covered by the load-bearing roofing tile (12) and adjacent in the eaves direction. At the ridge end, the carrier transmits the force from the load-bearing roofing tile (12) directly to a second roof batten (28), on which the roofing tiles (24, 26) in the second row (22) are suspended, and, at the eaves end, to a roofing tile (36), which is covered by the tiles (24, 26), in a subsequent covered third row (32).

Abstract: 1380942 Extruding vulcanized material MITSUBISHI PETROCHEMICAL CO Ltd 23 Dec 1971 [29 Dec 1970 26 June 1971] 60017/71 Heading B5A [Also in Division H1] A rubber material, e.g. polyisoprene or a diene rubber, or a synthetic resin material, e.g. polyethylene, containing a vulcanizing organic peroxide, is shaped as a copper electrical conductor covering, or as a tube, and vulcanized during passage through an elongate extrusion die, with the admission to the die surface of a lubricant having viscosity, absorption into the material, and gelling parameters within stated ranges as determined by specified tests. Numerous lubricants are specified, and the material may comprise various stated polymers, with examples being given of the extrusion of vulcanizable polyethylene coverings on to copper conductors precoated with a semiconducting vulcanizable polyethylene. In the covering of an electrical conductor w, the covering R is formed in an upstream portion 31 of the die, e.g. of less than 1 m. length, with the lubricant admitted under pressure from an annular chamber 42 through an annular porous die wall 41 upstream of, and optionally at other locations sequentially along, an elongate die vulcanizing portion, e.g. of 1 to 20 m. length, comprising a number of bolted together die sections 32, 33, upstream of a cooling section 5 through which the extrusion passes in contact with cooling water circulated under pressure. The die may comprise iron, brass, copper, or aluminium, and the vulcanizing section thereof may be heated by an electrical band heater 6, by a surrounding hot oil jacket, by passage of electric current through the die wall, or by induction heating, and the cooling section 5 is mounted for movement, e.g. on wheels, to permit thermal expansion and facilitate the addition and removal of die sections. A covering of polyethylene not containing vulcanizing agent may be applied to the vulcanizable covering intermediate the zones in which it is formed and vulcanized, to prevent direct contact thereof with the lubricant. In the extrusion of a tube Fig. 2 (not shown), the forming within the die is effected around a mandrel heated, e.g. by an internal electrical cartridge heater and similarly supplied with lubricant, and which may either extend only up to the entrance of the cooling zone, or may extend therethrough to support the tube.

Granted: 1989-11-22
Abstract: Coolent is passed through the source of heat which has an output decreasing with time, then to a steam generator. The steam produced is passed to an air cooled condenser and the condensate is returned to the steam generator. The novel feature of the proposal is the addition of an auxiliary coolant whose flow-rate is gradually decreased in line with the decreasing heat output of the source. The auxiliary coolant flow is stopped when the heat output of the source is reduced to the capacity of the air cooled condenser.

IPC: G01K7/36
Filed: 1989-10-13
Granted: 1993-05-12
Abstract: A method and an apparatus for automatically detecting the temperature of metallic rotatable bodies (8) without establishing any contact therewith. Electromagnetic energy is radiated by means of a transducer (B1), i.e. a solenoid in which an alternate current is passed, towards the surface of the metallic body (8) where induced currents are generated. The thickness of material penetrated by said currents is inversely proportional to the frequency of the solenoid current. The impedance variations in the material are detected by said solenoid (B1), and the relative signal is supplied to a computer (12) discriminating the signal relative to a resistivity variation of the same material, thus deriving the temperature of the body (8).
