Patent EP-0184847-A3 (EP)
IPC: C10L10/00
Filed: 1985-12-12
Abstract: A combustion process is disclosed for burning a fuel con­
taining sulfur characterized by low sulfur and particulate emission 
and formation of solid, non-toxic sulfur compounds. The process 
comprises mixing the sulfur containing fuel with an additive 
capable of reacting with sulfur; burning the mixture in a first 
combustion stage with less than 75% theoretical air and at a 
temperature below the melting point of the ash, but sufficiently 
high to cause reaction between the additive and any sulfur in the 
fuel to facilitate removal of the sulfur compounds formed; passing 
combustible fuel gases and particulates from the first stage to one 
or more further stages to complete the combustion of the fuel; and 
oxidizing, in a separate zone, sulfur compounds formed in the first 
reaction zone by reaction between the additive and the sulfur in 
the fuel to form non-toxic sulfates.

Title: Process for ploughing, in particular cables and laying plough for carrying out the process
IPC: E02F5/10
Filed: 1989-05-26
Abstract: For ploughing cables, a corresponding laying plough (18) has a cable chute (26) serving to guide the cable (10 ... 12). When only one cable is laid, a relatively narrow cable chute can be used, the clear width of which is slightly greater than the diameter of the cable. To lay a plurality of cables next to one another, the cable chute (26) would need to be of correspondingly wide dimensions, which requires an increased traction outlay for the laying plough (18) and a greater mound in the ground. The object of the invention is to permit the laying of a plurality of cables (10, 11, 12) without the abovementioned disadvantages. The process according to the invention provides that the cables (10 ... 12) are guided behind or above one another in a common vertical plane through the cable chute (26), and are only re-oriented shortly before the cables (10 ... 12) emerge from the cable chute (26). For this, the laying plough (18) according to the invention has a specially designed cable chute (26). The invention is particularly suitable for burying cables (10 ... 12) in sand, but also for burying other objects in sand which are to be laid in the ground (17), for example pipes, tubes or the like. <IMAGE>

Title: Mobile radio telephone
IPC: H04M1/724
Filed: 1989-07-04
Abstract: The invention is based on the object of developing a known mobile radio telephone in such a manner that data losses due to unintentional operation of operating and input elements, particularly by switching- off the radio telephone, are avoided. The object is achieved by the fact that a switching-off command by the microprocessor circuit (25) of the radio telephone (10) is only executed and that the mobile memory (18) can only be taken from the handset (11) when the following conditions are met. There must be no conversation taking place and all settings existing before the switching-off must have been transferred in the form of data into the mobile memory. During the later insertion of the mobile memory, the data stored in it are then transferred into a main memory (26) of the microprocessor circuit (25). The drawing shows a handset in perspective view and a radio transmitting and receiving set (12) connected thereto. <IMAGE>
