Abstract: In the process for reducing noxious compounds in the exhaust gases of a burner-fired smelting furnace, the material to be smelted is introduced into the furnace and supplied there with heat from a firing burner. For this purpose it is proposed that oxygen-rich gas is fed to the gas mixture flowing in the furnace, said gas being injected in such a way that the momentum of the gases from the firing burner and the momentum of the oxygen-rich gas supplied are oriented in parallel but not in the same direction. This produces gas turbulences in which the combustible pollutants are burnt and their discharge consequently prevented in the smelting furnace. <IMAGE>

Abstract: Compromise of a predetermined secure data processing routine (14, 49) by a procedure known as a "clock attack" is prevented by a method that inhibits synchronization with externally generated instructions by preventing determination of the time of execution of the predetermined data processing routine in relation to occurrence of an observable external event that precedes the execution of the predetermined routine. The method includes the step of (a) randomly varying the duration between the occurrence of the observable external event and the execution of the predetermined routine. Step (a) includes the steps of (b) executing one or more interim data processing routines (20, 21, 22, 52) between the occurrence of the observable external event and the execution of the predetermined routine; and (c) randomly varying the duration of said interim routines. Steps (b) and (c) may include the step of (d) randomly assembling m said interim routines for said execution from a group (52) of n stored routines having different durations, wherein m and n are integers, with n being greater than m. Step (d) may include either the step of (e) randomly accessing said m interim routines from a secure memory (51); or the steps of (f) randomly accessing pointers (58) for said m interim routines from a secure memory (60); and (g) accessing said m interim routines from a memory (51) in response to said pointers. Step (c) includes the step of (h) randomly varying the duration of the interim routines in response to dynamically processed data that does not repetitively recur each time said interim routines are accessed. The method further includes the steps of (i) monitoring (26) said interim routines to detect whether said interim routines are being tampered with; and (j) preventing (38) the execution of said predetermined routine in response to detecting that said interim routines are being tampered with. <IMAGE>

Abstract: When asymmetric olefins or a monomer mixture containing asymmetric monomers is polymerized by a catalyst composition containing esters of carboxylic acid e.g. as a so-called donor, and alcohol the ester group can be transesterificated with the alcohol to an ester containing another alkyl group during the preparation and/or polymerization of the catalyst. This is advantageous particularly when an adduct of a so-called spray-crystallized Mg-halide and alcohol is used as the catalyst carrier, because the alcoxy group of the alcohol of the carrier and the alcoxy group of the ester of the donor can be transesterificated and thus obtain the preferable effects of both esters on the run of the polymerization reaction. Hereby, a solvent having a high boiling point should be used as the intermediate agent, so that the transesterification reaction can take place. Most preferable have been found hydrocarbons having high boiling points, especially nonane and decane.

Date Sep. 19, 1991.An adjustable temperature gas feed is available that feeds firstly the grinder and secondly pre-drying means. At the outlet from the grinder, the gas that has passed through the grinder is combined with the gas that has passed through the pre-drying means to convey the ground material. The total gas flow rate QA at the oulet lies between a minimum flow rate and a maximum flow rate, and the flow rate Q1 of the gas passing through the grinder (1) is proportional to the quantity Qc of material placed in the grinder. According to the invention, a temperature T to be reached by the gas outlet temperature is set (optionally as a function of the moisture content of the material), and the gas feed is adjusted in such a manner that the feed gas is as hot as possible with the quantity of gas passing through the pre-drying means being limited to as little as possible. The method adapts to the material having different moisture contents and improves efficiency while leading to combustion with low NOx.

Abstract: A method of determining accurately acceptability of products of an injection molding machine under whatever environmental conditions said machine is operated, which is executed by a processor (22) of a numerical control device (20). The processor, upon deciding that auxiliary acceptability determination based on at least one of operation parameters directly indicating environmental conditions relating to the acceptability of products including the surface temperature of the metallic mold, outdoor temperature, and wind velocity is required in addition to regular acceptability determination of products based on molding process parameters, reads output data from A/D converters (11, 12 and/or 13) corresponding to the actual value of at least one operation parameter detected by relative mold temperature sensor (8), outdoor temperature sensor (9), or wind velocity sensor (10). The processor generates rejection signals when it finds any one of the actual values of operation parameter deviating from an allowable range and recognizes a possible molding rejection. When all of at least one type of operation parameters fall within an allowable range, regular acceptability determination of products is further performed.
