Patent DE-3333762-A1 (DE)
Title: All-wheel drive for motorcycles
Inventor: PRIEBE ROLAND
IPC: F02B61/02
Filed: 1983-09-19
Abstract: The all-wheel drive for motorcycles is principally intended to improve their riding safety. Instead of a conventional telescopic fork, here a single-arm rocker is installed at the front, an axle leg which holds the front axle and is steered via a slider rod being rotatably mounted at the front end of said rocker. The front axle is connected, depending on the design of the secondary drive, to a ring gear or a chain gear via a homokinetic joint which makes it steerable. In the case of motorcycles with a longitudinally extending transmission output shaft, the ring gear is used and driven via a conical gear which is seated at the end of an articulated shaft which leads forward. This articulated shaft rotates at the same speed of rotation but in the opposite direction as the one driving the rear wheel and is connected to the transmission output shaft via gears. In the case of motorcycles with a transversely extending gear output shaft, the chain gear is used and driven via a roller chain which leads forward. A roller chain towards the rear drives the rear wheel in a customary manner. The two roller chains are driven by two chain pinions which are dimensioned in the same way and are seated one next to the other on the transmission output shaft.

Title: Process and apparatus for purifying flue gases
Inventor: BENGTSSON SUNE
IPC: B01D53/81
Filed: 1983-09-21
Abstract: In the purification of flue gases from sulphur dioxide by flue gas desulphurisation using calcium hydroxide as absorbent, a sulphite-containing waste is obtained. The sulphite is then oxidised to sulphate in the form of anhydrite. In this case, a rotary oven receives the sulphite-containing waste and there are devices to feed the flue gas having excess air in cocurrent with the waste through the oven with oxidation of sulphite to anhydrite. The anhydrite can be used, inter alia, in the production of cement.
Patent DE-3335974-A1 (DE)
Title: Dolphin water ski
Inventor: NIKLAS FRANZ
IPC: B63B34/56
Filed: 1983-10-04
Abstract: The invention relates to a dolphin water ski. It serves for propelling a person on water under his own power at walking speed (5 km/h), which can be increased to about 8-10 km/h by means of large tensioned fins, on still water. This is accomplished by actuating the tensioning device or by choosing stronger tensioning elements (interchangeable) by which the tension in the large fins is increased. For operating the dolphin water skis, 2 floats with foot recesses and 2 pushing sticks are required. The floats consist of a glass fibre construction (glass fibre reinforced plastic) and are filled with lightweight foam. Under the alternating action of the forces "P" (weight displacement from one float to the other) and with the aid of the pushing sticks, weight being predominantly at the stern (drawing Fig. 3, broken line = water surface), the large fins begin to oscillate and produce a forward thrust, which enables a practised operator to reach the speeds mentioned above. By pressing down the front parts with the pushing sticks "P3" in Fig. 3, the braking effect is achieved. The volume of the floats should be divided into classes, graded according to the weight of the operators. Rule of thumb: vol. = weight/operator plus dead weight of a float in l and kg. Vol = 75 kg/op. plus 10 kg/d.w. = 85 l. Finally, it should be mentioned that the dolphin water ski is a device for water sport and leisure.

Title: Agricultural machine
Inventor: LINK ALFRED ING GRAD
IPC: A01B35/22
Filed: 1984-01-19
Abstract: An agricultural machine for planting potatoes has, for each planting row to the produced, a rocker (5), on which are mounted a pre-coulter (9) and covering-over discs (7). By means of two tension springs (17, 18), the downwardly directed force of the covering-over discs (7) and of the pre-coulter (9) can be adjusted. This purpose is served by an adjusting nut (13) which is screwed onto a threaded spindle (12). The adjusting nut (13) can move onto an upper end face (14) of a tube (11), so that, in the event of a further stroke, this tube (11) moves downwards, the result of this being that the pre-coulter (9) and the covering-over discs (7) are raised. <IMAGE>

Patent DE-3417092-A1 (DE)
Title: Vertical electric filter
Inventor: KAFITZ WALTER
IPC: B03C3/36
Filed: 1984-05-09
Abstract: The invention relates to a vertical electric filter with collecting electrodes (8) and with emission frames (2) for emission electrodes (4) which are arranged in channels (22) between the collecting electrodes (8). In a known vertical electric filter, guiding plates are provided on the housing longitudinal walls, the outermost channels being directly terminated by the housing longitudinal walls; collecting electrodes are not present on the housing longitudinal walls. Hitherto, in the end zones of these channels (22) only inadequate filtering took place especially since the distance between emission frames (2) and housing end wall (6) had to be of comparatively large specifications. There is a risk of flashovers between housing end wall (6) and emission frames (2) due to collections of dust on the housing end wall. In order to be able to overcome these difficulties with a small degree of outlay, it is proposed that guiding plates (18) be provided in the region of the housing end wall (6) in order to deflect the flow of gas from the housing end wall (6) into the electric field of the electrodes (4, 8). The guiding plates (18) are arranged directly under the emission frame (2) and/or between the dust chutes (10) and/or at a predetermined point in the region of the electric field, the upper ends (25) of the guiding plates (18) terminating at least approximately directly at the housing end wall (6). <IMAGE>

Title: Hydrodynamic magnetic pump
Inventor: KRUEGER-BEUSTER HELMUT
IPC: F04B43/09
Filed: 1984-08-23
Abstract: A helical, hose-like winding arrangement is coiled about the core of a surface travelling-field magnet, like a three-phase motor stator. In the outer hose layers, that is in those remote from the core centre, a magnetisable insert is provided. In a form of peristaltic movement, the travelling rotary field produces hose knots and bulges, which altogether are capable of conveying the contents of the hose. Any other supported parts or a housing can be dispensed with. All liquid or pasty substances can be conveyed. By appropriate selection of the hose width and number of turns on a core, the delivery amount and delivery pressure can be varied within wide limits. Parts to be sealed off such as shafts and the like are dispensed with as are drive motors, so that corrosive chemical substances can be just as easily conveyed as sensitive biological materials. The very simple construction permits cost-effective mass production, so that this pump should become widely available.

Title: Device for securing roller blinds on caravan windows and the like
Inventor: SCHMITT THOMAS
IPC: B60J1/20
Filed: 1984-09-21
Abstract: Upper and lower roller blinds (1, 2) guided in vertical guide grooves (7) of caravan windows and the like have a respective roller-blind locking profile (5, 6), which profiles can be connected to each other by means of a closure hook (14). By means of the spring tension exerted by the roller blinds (1, 2), the ends of the roller-blind locking profiles (5, 6) tilt into the guide grooves (7). By this means the roller-blind locking profiles (5, 6) are firmly clamped in the respective position. If the two roller-blind locking profiles (5, 6) are pressed towards each other by hand, they are supported against each other via a spacer (18), so that the tilting action and hence the clamping in the guide grooves (7) are cancelled. The two roller-blind locking profiles (5, 6) can be moved together along the guide grooves (7). <IMAGE>

Patent DE-3503734-A1 (DE)
Title: Door shuttering
Inventor: GRAF OTTO
IPC: E04G15/02
Filed: 1985-02-04
Abstract: The invention provides a door shuttering which can be re-used again and comprises profile cheeks, of which at least the upper transverse cheek is divided and can be adjusted in its length by means of a slot connection. The two transverse-cheek parts are fastened at the top of the side cheeks by means of hinges and can be folded upwards at right angles for mounting and folded downwards at the side cheeks for demounting and transportation. The lateral spacing of the two side cheeks in a door opening is fixed by means of expanding mandrels which can be adjusted in length. Forming the cheeks by profile sheets welded to one another ensures sufficient stability and resistance to buckling, with the result that good dimensional stability is ensured in the long term, even when the shuttering is frequently re-used.
