Title: Combustion installation for fuels of high chlorine content
Inventor: LOESEL GEORG DIPL ING
IPC: F23J15/08
Filed: 1987-04-21
Abstract: In a combustion installation for fuels of high chlorine content, the problem of high-temperature chlorine corrosion arises. This limits the maximum wall temperature. In addition, the energy required for reheating the flue gases downstream of a flue gas purification plant adversely affects the overall efficiency of such combustion installations. In this respect, the invention provides that the waste gases of an externally heated final superheater are directly mixed with the primary flue gases. In addition, a surface burner or muffle burner unit can be used for further heating of the purified flue gases. The combustion installation is suitable in particular for the combustion of fuels of high chlorine content, in particular of refuse or of carbonization gas obtained from refuse. <IMAGE>

Patent DE-3722652-A1 (DE)
Title: Process for producing cement suspension
Inventor: SAMOL HERBERT
IPC: C04B7/52
Filed: 1987-07-09
Abstract: The invention relates to a process for producing cement suspensions with an especially fine average grain size of approx. 3 to 6  mu , defined by a 50 % sub-sieve fraction. Suspensions of this kind are required for injection purposes for soil consolidation or for soil sealing and for repairing building structures. The penetration depth of such fine suspensions is greater than that of suspensions of standard cements. The aforementioned suspensions were hitherto made from extremely finely ground cements which have various disadvantages. According to the present invention, a standard cement with a relatively coarse average grain size, which is above that required, is mixed with a liquid to form a basic suspension and pumped through a separator, the finest proportion being separated off, as a fine suspension in the overflow from the separator, for the aforementioned further use until the desired average grain size is established. The coarse suspension in the underflow of the separator may be passed on for other uses. <IMAGE>

Filed: 1987-08-28
Abstract: Mixing apparatus comprises a container which may be in the form of a hollow cylinder with its axis horizontal. It contains mixing means mounted to rotate within the container about its axis and in addition a pulveriser mounted in the cylindrical wall of the container. Whereas in known mixers of this kind the additional pulveriser comprises so-called knife heads which do not in every case grind down sufficiently rapidly and uniformly the material to be treated, in the mixer now proposed the grinding of the material is improved by the addition of a shearing effect. The pulveriser comprises two concentrically arranged relatively rotatable shearing rings and is in a position to disintegrate even materials which are difficult to treat, such as damp materials, rapidly and at the same time efficiently. Fluid can also be added in the region of the pulveriser without the material being caused to form into lumps.

Title: Protective housing for transmitters and/or radio receivers of a device which is used in underground mining
Inventor: WEBER KARL-HEINZ DIPL ING
IPC: H04B1/034
Filed: 1988-03-12
Abstract: Until now, transmitters or radio receivers have been fitted on or inside the machine body of the machine or device which is used underground and have been connected via coupling elements to the appliances located in a flameproof area. The subsequent arrangement of a transmitter or receiver is thus made more difficult. In addition, the radio-frequency losses caused by the connection points become noticeable as interference. It is proposed to fit the protective housing (2), which is used to accommodate the transmitter and/or receiver, instead of a cable entry or instead of a coupling element or plug to the flameproof device or machine (1) in such a manner that it completely terminates the area to be protected but can also be connected to the circuit of the terminated housing area and can be equipped with an antenna (5) which can be fitted from the outside. <IMAGE>
Patent DE-3818265-A1 (DE)
Title: Controller for a heating system
Inventor: WEINMANN WOLFGANG
IPC: F23N5/00
Filed: 1988-05-28
Abstract: Controllers for heating systems use actuating elements which influence the combustion air-feed and thus the ratio of the latter to the fuel feed so that there is only a minimum oxygen excess in the exhaust gas so that a minimum quantity of pollutants and an almost optimal efficiency results. The said controllers and their actuating elements are complex. The novel controller and its actuating element are, in contrast, to be simpler. The novel controller leaves the volumetric ratio between the fuel and air unchanged and affects the control by influencing the volume-specific calorific value of the fuel via the temperature dependence of its density, for which purpose a controllable continuous flow heater which is operated electrically or with waste heat and is situated in the fuel feed is used an actuating element. The controller and the actuating element are suitable for heating systems having a burner and for heating systems having a diesel motor with utilisation of waste heat. <IMAGE>

Title: Electrically triggering pyrotechnic force element
Inventor: KRAUS MANFRED
IPC: F15B15/12
Filed: 1988-06-16
Abstract: An electrically triggering pyrotechnic force element (11), as is used especially for driving pivoting structures - for example for extending a projectile gliding wing - is intended to achieve a more favourable efficiency with a more compact construction. To this end, the design on based on a gear conversion of a linear piston-rod movement into a pivoting movement and, instead of this, the piston (14) itself moves around the pivoting shaft (13) in the gas pressure area (15) which runs in a correspondingly curved manner. In consequence, the gas pressure area base (16) can be used as a stationary shaft (18) for holding the pivoting structure (12) which is guided by means of a hollow-cylindrical gas pressure area housing (17) on the cylindrical outer surface of the shaft (18), which has an approximately semicircular cross-section. The opposite half of the area inside the housing (17) is split by a piston (14) which projects from the cylindrical inner envelope surface of the housing (17) onto the shaft (18) and is guided there concentrically with respect to the pivoting shaft (13). <IMAGE>
