Patent DE-3700553-A1 (DE)
Title: Process and reaction apparatus for dry flue gas desulphurisation
Inventor: VIESSMANN HANS DR
IPC: B01D53/50
Filed: 1987-01-10
Abstract: The process serves for dry flue gas desulphurisation by powdered limestone (CaCo3) in the combustion of sulphur-containing bituminous coal, the powdered limestone being injected superstoichiometrically into the reaction chamber and the flue gases, after passage through a filter, being fed to the stack. In order to significantly reduce the amount of additive to be fed and thus to be able to operate the entire desulphurisation operation more economically, the powdered limestone is injected into a zone of the reaction chamber, the temperature of which is 20-200@C, preferably 100@C, higher than the temperature optimum, between 800 and 1000@C, of the binding of SO2 to CaO. The fly dust is precipitated in a settling chamber directly downstream of the reaction chamber and the fly dust portion precipitated there is added back to the continuously fed fresh powdered limestone before its injection into the reaction chamber.

Title: Arrangement for exchanging and storing display panels
Inventor: BRISCOE DAVID
IPC: G09F11/30
Filed: 1987-02-18
Abstract: The invention relates to an arrangement for exchanging and storing display panels, there being provided two storing regions in which the display panels are mounted such that they can move perpendicularly to their surfaces, the storing regions being bordered by two planes in which transportation of the display panels between the storing regions takes place, and at least one of the planes being provided for displaying a plurality of display panels (displaying plane). Arranged on the display panels, for transportation of the same, are toothed racks which, during transportation, are in engagement with gearwheels. The invention provides means which, when the display panels pass from the storing regions into the planes, move the gearwheels into engagement with the toothed racks. The means may be formed by eccentrics which engage into recesses of rollers of the display panels. The means may, however, also be formed by rotary discs, the axes of which run essentially parallel to the displaying planes, said rotary discs being provided with in each case at least one slot which extends from the circumference and in which a gearwheel is arranged such that a toothed rack arranged on the display panel, on introduction into the slot, passes into engagement with the gearwheel.
Patent DE-3709265-A1 (DE)
Title: Hydraulic brake system with brake slip control
Inventor: REINARTZ HANS-DIETER
IPC: B60T13/14
Filed: 1987-03-20
Abstract: A brake system for a brake with slip control is presented. For safety reasons, brake systems of this type should be provided with a return device for the master cylinder so that, should the hydraulic supply fail during slip control, a volume of pressure medium sufficient for the normal braking then necessary is available in the master cylinder. This problem is solved in that a reserve volume chamber (35) is formed, which is defined by a piston (33). The piston (33) is acted upon by the pressure in the booster chamber (14) as soon as slip control commences. The pressure medium in the chamber (35) is then displaced into the working chamber (5) or (6) by way of the non-return valve (41) or (42). This reserve volume is then available for normal braking should the slip control be put out of operation during a control sequence. <IMAGE>

Title: Device for the mounting of agricultural distributor machines on the three-point linkage of a vehicle
Inventor: HOFF WALTER
IPC: A01C15/00
Filed: 1987-11-20
Abstract: Agricultural distributor machines, such as fertiliser spreaders, sprayers or the like, having widely projecting distributor lines are mounted on the three-point linkage of vehicles, for example tractors, which consists of a freely movable upper link and two lower links arranged next to one another. The lower links are each raisable and lowerable by means of a hydraulic cylinder supported on the vehicle. So as not to transmit transverse movements of the vehicle to the distributor lines, the two lower links to the three-point linkage are suspended on a crossmember which is pendulously mounted on a bearing arranged centrally between the lower links, elastically resilient supporting members being inserted between each hydraulic cylinder and the crossmember on both sides of the bearing. Such a device can be integrated into any three-point linkage and does not lead to an increase in the weight absorbed by the three-point linkage or to a greater overall length. <IMAGE>

Title: Method for controlling the modulation pressure in an automatic transmission
Inventor: HAUBNER GEORG
IPC: F16H61/00
Filed: 1988-03-03
Abstract: A method for controlling the modulation pressure in an automatic transmission with the aid of engine data characteristic diagrams is proposed in which the number of a memory cell of the characteristic diagram is stored as a value which is combined from two engine parameters. The memory location number is an eight-digit digital number in which the upper three bits are determined by the load and the lower five bits by the rpm. In the characteristic diagram, digital values which drive a hydraulic controller as digital reference by means of a mark to space ratio to a control circuit are assigned to the memory numbers, which hydraulic controller builds up a pressure corresponding to the current. <IMAGE>
Patent DE-3807918-A1 (DE)
Title: Safety screw
Inventor: DINSTUEHLER MANFRED
IPC: F16B31/02
Filed: 1988-03-10
Abstract: Safety screws are used for fastening components and devices, and they cannot be released by tools after mounting without having to take destructive measures. Consequently, demounting and theft or the like are prevented. The safety screw 1 is delivered with the screw-head piece 2 represented by chain-dotted lines, the portion 3 and the truncated cone piece 4 as screw head. After mounting is complete, the hole 5 with the diameter 6 is brought to the diameter 7 by drilling, as a result of which the screw-head piece 2 and the portion 3 are done away with. Consequently, it is no longer possible to unscrew the safety screw 1; it can only be removed by destroying the truncated cone piece 4. <IMAGE>

Patent DE-3838005-A1 (DE)
Inventor: KJAERULFF SVEND JOERGEN
IPC: G05D23/19
Filed: 1988-11-09
Abstract: In a method of setting the mean temperature (TV) at which a heating medium is supplied in a heating apparatus (5), heating the medium intermittently, of e.g. a domestic heating system comprising at least one adjustable throttling point (16, 17, 18) through which the heating medium passes, a desired supply temperature (TS) is determined by pre-setting means 1 from external factors (H, Texternal) and the heating medium is heated to the desired supply temperature (TS) with the at least one throttling point (16, 17, 18) fully open. A function representing the starting characteristic with which supply temperature (TV) changes with heating is determined at 6, at least one parameter (Cm) of the starting characteristic function, and the modified desired supply temperature (TF) is changed until the progress of the heating has conformed to the desired characteristic function in each heating phase. <IMAGE>
Patent DE-3838550-A1 (DE)
Title: Throttle valve adjuster
Inventor: REULEIN HERMANN DR
IPC: F02M3/06
Filed: 1988-11-14
Abstract: Due to malfunctions, throttle valve adjusters of this type have a tendency to undesirable increase of the engine speeds and when used in motor vehicles, therefore, can cause dangerous driving situations.   The said disadvantage is avoided by the new throttle valve adjuster. The new throttle valve adjuster is characterised in that, in the event of malfunctions, a fault signal activates a hydraulic, pneumatic or electromagnetic actuator incorporated in the adjuster tappet and the adjuster tappet experiences a longitudinal adjustment which leads to the engine speed being reduced to a maximum admissible value. Throttle valve adjusters of this type have applications especially in the motor vehicle sector.

Title: Device for transmitting mechanical forces in the longitudinal direction by means of a flexible steel wire spiral shaft
Inventor: NEUDERT WILLIBALD
IPC: F16C1/20
Filed: 1988-12-09
Abstract: In the transmission of forces by the longitudinal displacement of a flexible shaft which consists of a tightly wound steel wire spiral with an inner steel cable wound in the opposite direction to the steel wire spiral, with the latter being secured against rotation by a connecting element at at least one end, use is made of a nut, the inner contour of which is matched to the outer contour of the steel wire spiral of the flexible shaft. The nut is driven, for example, by an electric motor that can be driven in both directions of rotation and has a gearbox suitable for this purpose. The use of a guide tube which can be bent in any way desired makes it possible to transmit a force over relatively large distances and around bends without problems. The use of a steel wire spiral which is shorter than the inner steel cable makes it possible to transmit forces under spring loading. The force transmission device is excellently suited to overcoming the resistance of levers with dead-centre springs and for operating electrical switches and for the infinitely variable adjustment of nonreturn valves subject to spring loading.
