Title: Gun-barrel projectile cartridge having a spin-stabilised projectile for hunting and policing purposes
Inventor: ROSENBERGER MANFRED R DR
IPC: F42B7/10
Filed: 1983-02-09
Abstract: According to the state of the art, it has hitherto been impossible to offer a satisfactory solution in respect of a stabilisation of the spin of gun-barrel projectiles. Projectiles of this type therefore always have been and still are only a last resort of low efficiency. In contrast, the cartridge according to the invention provides an ammunition, the projectile of which is spin-stabilised in a simple way and is characterised by a relatively high flying speed and a low dispersal around the target point. It is notable, furthermore, that this ammunition, when fired both from cylindrical and from choke barrels, exhibits a uniform behaviour and is suitable for hunting and policing purposes.

Title: Process for reducing the NOx emissions downstream of fossil-fuel power station boilers with simultaneous utilisation of the heat of reaction to heat up the gases downstream of flue gas desulphurisation
Inventor: HOELTER HEINZ DIPL ING
IPC: F23J15/08
Filed: 1983-09-27
Abstract: It is known to decrease by catalytic route the nitrogen oxides contained in the exhaust gases of fossil-fuel power station boilers and to decrease the sulphur oxide likewise present in these exhaust gases by flue gas desulphurisation. Since it is frequently required, depending on the position of the power station, to elevate the scrubbed flue gases to at least 80 DEG C, according to the invention it is proposed that the heat from the NOx reduction (2) is utilised to reheat the scrubbed flue gases downstream of the flue gas desulphurisation (4) via a heat exchanger system (5) which is connected upstream of a stack (6). Some of the heat produced can additionally be uncoupled as utility heat. <IMAGE>

Patent DE-3404833-A1 (DE)
Title: Method and apparatus for rolling metal foils
Inventor: GUETTINGER HEINZ
IPC: B21B37/36
Filed: 1984-02-08
Abstract: When rolling aluminium foils, particularly very thin foils, in a range up to 10  mu m, improved uniformity of the foil thickness across the width of the web with a simultaneous increase in the speed at which the web is pulled during rolling is achieved by virtue of the fact that operations are carried out at a working point of the line force/deformation characteristic which is below the saturation range, in which, although the deformation is virtually independent of the line force, the pulling speed is determined by the other parameters and cannot be varied. The fluctuations in thickness which occur across the width due to variations in the line force when such a working point is chosen are compensated by the fact that the line force is controllable and is controlled in such a way that the reduction in thickness across the width is constant or has a desired profile. It is possible to achieve this, for example, by designing one of the rolls as a flexure adjustment roll with a series of pressure elements with controllable contact pressure distributed across the width of the roll.

Patent DE-3409626-A1 (DE)
Title: Multipurpose soap dispenser
Inventor: NEUSTEIN GUSTAV
IPC: E03C1/046
Filed: 1984-03-16
Abstract: The multipurpose soap dispenser can be used anywhere where operations have to be carried out using liquid soap or detergents. The functioning of the multipurpose soap dispenser is essentially due to the injector (7) situated in the unit. Since the setting cone (14), located in the lower part (80, is provided with one bore having a diameter of 10 mm and another having a diameter of 5 mm, these being drilled at an angle of 130 DEG  with respect to their axes, it is ensured that, in addition to the closed (Z) position, by setting the washing (W) or showering (B) position both operations can be carried out independently of each other. This is made possible by the 5-mm channel being drilled upstream of the 10-mm channel and bypassing the latter, as a result of the angular position in the setting cone (14). In the washing (W) position, the water jet streaming out of the nozzle of the injector (7) carries along the liquid soap situated in the unit and pushes this, via the 5-mm throughflow channel (6), into the shower hose. In the showering (B) position, the entire quantity of water flows through the unit. The backflow preventer (3) located in the head part blocks the water flowing back out of the shower hose. <IMAGE>

Title: Device for cleaning reflectors on road reflector posts
Inventor: SCHWARTZ HEINZ
IPC: E01F9/619
Filed: 1984-03-16
Abstract: The automatic cleaning of reflectors on road reflector posts takes place by the actuation of a wind blade arranged on the right side of the reflector post on a pivotable lever system, as a result of which, on the left end of the lever system and a joint piece, a geometrical shape changes and a cleaning member, similar to a windscreen wiper, runs across the reflector. The actuation of the wind blade takes place by gusts of wind which arise as a result of air displacement at the roadside when fast or large-volume motor vehicles pass the road reflector post. After the motor vehicles have passed, the geometrical shape, and thus the cleaning member, cleaning again by spring force, return into their starting position.
