Abstract: A removable mount for mounting an electronic system component on a forklift includes, in one embodiment, a mounting plate having a major surface for mounting the electronic system component and an inverted J-shaped part located at a top portion of the mounting plate. The inverted J-shaped part is adapted for mounting the mounting plate on an unmodified original equipment manufacture (OEM) carriage of the forklift or an unmodified OEM sideshifter of the forklift. The mounting plate also has a slot to accommodate a fastener for anchoring the mounting plate to the unmodified OEM carriage or to the unmodified OEM sideshifter.

Abstract: In one of several embodiments, an RFID system for a forklift incorporates a metal plate to which is attached an electronic circuit assembly. Also attached to the metal plate, is an antenna assembly housing an RFID interrogator antenna and/or a wireless local area network (WLAN) antenna. The metal plate operates as a ground plane to the antenna assembly and also serves as a mounting plate for mounting the RFID system on a sideshifter or a carriage of the forklift.

Abstract: A condensate which contains cyanide ions, hydrogen sulfide and ammonia is first partly purified by stripping with water vapor and stripped-off gases are then scrubbed with an absorbent. The laden absorbent contains 50 to 300 grams ammonia and 10 to 100 grams hydrogen sulfide and is at a temperature of 70.degree. to 150.degree. C. and has a pH value of at least 9. Sulfur is added to the condensate or the laden aqueous absorbent in a quantity which is at least 0.8 times the quantity that is stoichiometrically required to convert the cyanide ions to thiocyanate ions. The sulfur may be produced from hydrogen sulfide and oxygen, preferably in the presence of an oxidation catalyst. Alternatively, the sulfur may be added to a liquid which contains 10 to 400 grams ammonia and/or ammonium ions per liter so that ammonium polysulfide is formed. That solution is mixed with the liquid that contains cyanide ions.

Abstract: Gas condensates formed from the gases obtained from coal gasification, cokefication, or carbonization are extracted with an acid- and alkali-resistant solvent, e.g. organic esters or ethers, and phenols are thereby removed. The extract is separated into solvent and phenolic phases and the solvent is recycled to the extraction process. The same solvent is used in a greater quantity for a second stage treatment of the gas condensate to preferentially remove tar bases and again the solvent and tar base phases are separated with recycling of the solvent. Residual solvent, acid gases and other volatile components are removed from the gas condensate by distillation and/or stripping with the ammonia and acid gases being separately recovered. The gas condensate is thereafter subjected to biological cleaning, e.g. by a biological oxidation.

Abstract: The aqueous effluent liquors from gasification or de-gasification of coal are extracted with a water-insoluble solvent and the extract is processed to recover the solvent. The aqueous residue is treated to remove NH.sub.3 in a driving-off column.

Abstract: Mono and polyvalent phenols are recovered from gasified coal by scrubbing the phenol-containing gas with water, separating the extracted phenols into a monovalent phenol-rich fraction and a polyvalent phenol-rich fraction and recovering the monovalent phenols separately from the polyvalent phenols by solvent extraction.

Abstract: A process for removing phenols from waste water resulting from the gasification or carbonization of coal and containing CO.sub.2, H.sub.2 S and NH.sub.3, comprising mixing the waste water with a low-boiling organic solvent, separating the mixture into a solvent layer and an aqueous layer, stripping off from the aqueous layer under superatmospheric pressure the vapors of CO.sub.2, H.sub.2 S and organic solvent contained therein, then stripping off from the aqueous layer the NH.sub.3 contained therein leaving a refined aqueous product layer suitable for discharge, scrubbing the stripped vapors under superatmospheric pressure with a portion of the cold refined product to remove organic solvent contained therein, condensing part of the solvent and separating it under superatmospheric pressure, and scrubbing the remaining acid gases still containing ammonia and solvent with recirculated cooled raw phenol to remove the ammonia and solvent.

Abstract: Mono and polyvalent phenols are recovered from gasified coal by scrubbing the phenol-containing gas with water, separating the extracted phenols into a monovalent phenol rich fraction and a polyvalent phenol rich fraction and recovering the monovalent phenols separately from the polyvalent phenols by solvent extraction.

Abstract: Pure, concentrated ammonia is recovered from aqueous liquors by stripping off gas water, de-acidifications, scrubbing and withdrawing ammonia from the top of a scrubbing column.

Abstract: A process for the recovery of pure concentrated ammonia in which the gaseous products of coal gasification or degassing are condensed or are washed with water to produce a phenolic-containing liquid phase (gas water), this liquid is dephenolated by extraction with a solvent, the phenol is recovered from the solvent and the gas is driven from the liquid phase. The gas is washed with circulated phenol and residual solvent is eliminated therefrom after NH.sub.3 is removed by washing.

Abstract: Monohydric and polyhydric phenols are removed from waste water together with hydrogen sulfide, free and combined ammonia, by extraction and distillation. The waste water is formed during the degasification or gasification of coal and is subsequently subjected to biological purification.The steps of the process are as follows:1. Removing a major portion of the monohydric phenol, part of the polyhydric phenol and any free fatty acids present in the waste water by extraction with a small amount of a non-saponifying organic solvent having a boiling point below 100.degree. C;2. separating the phenols from the extract by distillation;3. Removing a major portion of the polyhydric phenols, the remaining monohydric phenols and any free acids by a single or repeated extraction with a large amount of the same organic solvent from the refine phase from step (1).4.

Abstract: Dissolved organic compounds in waste water resulting from coal degassing or gasification processes are removed by extraction with a solvent which is substantially water-immiscible, the solvent residues in the waste water are removed by inert gas scrubbing, and CO.sub.2, H.sub.2 S and NH.sub.3 in the waste water are removed by heating and steam contacting. NH.sub.3 is effectively removed in a steam gas/liquid contacting column by feeding the condensed head product of the column back to the top portion thereof, withdrawing a portion of the condensate from the column at a level intermediate the top and bottom portions of the column, treating the condensate in admixture with waste water containing CO.sub.2, H.sub.2 S and NH.sub.3 in a deacidification gas/liquid contacting column, and feeding the sump product of the deacidification column to the first column at a region below the region at which the condensate is withdrawn but intermediate the top and bottom portions of the NH.sub.3 -removal column.
