Title: Process for removing pollutants from a gas resulting from the low-temperature carbonisation of waste materials
Inventor: BAUMGART ERNST-WOLFGANG
IPC: B01D53/52
Filed: 1988-07-08
Abstract: Gas which contains considerable amounts of pollutants is formed in the low-temperature carbonisation of waste materials. These pollutants must be removed from the gas. In order to separate out the pollutants from the gas without use of chemicals and in an environmentally-protecting manner, the gas is first passed through an absorber (14) in which the pollutants are dissolved in water. The water is then conducted through a degassing device (22) in which the water is freed from the pollutants by air. The air loaded with pollutants is passed through a burner apparatus (88) in which the pollutants are burned. The process is suitable for use in pyrolysis plants. <IMAGE>

Patent DE-3830560-A1 (DE)
Inventor: WOHLWEND RICHARD J
IPC: F16B13/10
Filed: 1988-09-08
Abstract: A dowel, especially for fastening in drillholes in concrete, consists of a spreading tube (1) and of a spreading wedge (2) arranged in this, the spreading tube (1) being equipped, in the region of its tube end (10) to be introduced into a drillhole, with orifices (7) extending parallel to its longitudinal mid-axis (8) and limiting tube portions, and there being formed on the spreading tube (1) spreading faces (11) and on the spreading wedge (2) wedge faces which bear against one another and which cause the tube portions to spread open as a result of an axial displacement of the spreading wedge (2) relative to the spreading tube (1) in the direction of the tube end (10). In order to achieve a very high pull-out resistance and especially a high degree of safety against release in the event of cracks in the region of the drillhole, whilst also ensuring a simple design, the spreading wedge (2) bears with its wedge faces against the spreading faces (11) which limit orifices serving as spreading orifices (7), and the spreading wedge (2) has a wedge orifice (16) which is open towards the tube end (10) and in which is arranged a counterwedge (3) spreading the spreading wedge (2) out of the spreading orifices (7). <IMAGE>

Title: Internal combustion engine with cam mechanism on the two-stroke principle
Inventor: BOHNE WERNER
IPC: F01B9/06
Filed: 1988-09-20
Abstract: In current internal combustion engines of conventional construction, disadvantages of a mechanical nature are still inherent in the crankshaft, connecting rods and pistons; for example a large design cost is necessary in order to minimise inertial forces. For this purpose, it is necessary to use balancing shafts and counterweights. It may furthermore be mentioned that all parts connecting the crankshaft to the piston by way of the connecting rod must be designed as bearings. The design cost is high and there are disadvantages in the form of friction and heat. In the conventional construction, piston tilting is thus unavoidable. The disadvantages, only partially listed here, can be considerably reduced by the abovementioned invention. Since the cylindrical piston will continue to be indispensable in the construction of internal combustion engines, a new course can be pursued by means of the cam mechanism, see Fig. 3 in the abovementioned embodiment. This design form with opposing cylinders can also be designed with a plurality of cam units in in-line construction. Another possibility for control in the inlet and exhaust area in two-stroke engines is to obtain an improved efficiency by rotating the pistons which are provided with a bevelled edge. A four-stroke construction is feasible. <IMAGE>

Patent DE-3832851-A1 (DE)
Title: Horizontal air-vane rotor
Inventor: ZIMMER CORNELIUS P
IPC: F03D3/02
Filed: 1988-09-28
Abstract: The application has the purpose of optimising the wind energy and of replacing the monstrous-looking generators on individual masts with an aesthetically pleasing quasi-windmill building in which the entire drive mechanism is accommodated. The main characteristic of the invention is the generator drive. Rotatably mounted at the upper end of the vertical generator axle is a double-sided lever beam which divides the lever beam into two lever arms of equal length. Proceeding an equal distance on each side from the axle bearing is located, at right angles to the beam, in each case one arm which is connected to the generator armature frame. The double-sided lever beam is caused to rotate by the V-belt wheels, the grooved friction wheels rolling over the stationary V-belt. The lever beam rotating in this manner simultaneously causes the generator armature to rotate. The armature engagement point is thus situated outside the G-armature. When the generator diameter is correspondingly larger, the cutting speed between the magnetic field and the armature accelerates. With the lever rotational engagement the ratio "input to output" is reduced advantageously with constant "output". A variable moment-of-inertia device is provided.

Title: Apparatus for driving winding beams to be fed with web-like material
Inventor: ALDER GUENTER
IPC: D02H13/12
Filed: 1988-12-24
Abstract: So that winding beams of beaming machines can be driven in the same direction and at different rotational speeds, there is between the weaving beam (1) and its drive motor (4) a step-up gear (3) which has a drive and a driven shaft (9 and 10) and, between them, two gear trains (I and II) which run parallel to one another and are to be coupled and uncoupled in opposition and which have different step-up ratios. In order to arrive at a step-up gear (3) having as simple a construction as possible and at an easier change-over in rotational speed, two three-wheel couplings (16 and 17), one acting in opposition to the other, are installed one in each case in the two gear trains (I, II) having different step-up ratios, and the drive motor (4) preceding the drive shaft (9) is to be operated with a variable direction of rotation and is to be changed over accordingly.   <IMAGE>

Title: Vending machine for pancakes or the like
Inventor: MLADEN PAUNOVIC
IPC: G07F11/52
Filed: 1989-01-19
Abstract: The object of the invention is to heat pancakes or the like without human service and to dispense them to the customer. The problem is solved by storing the pancakes in a drum-like container. An individual pack with pancakes falls from there into the microwave oven, where it is heated, and is subsequently conveyed to the serving orifice by means of a dispensing mechanism. The pulse of the coin tester sets the drum-like container in motion. When the pancake pack reaches the lowest point, where an orifice is located on the immovable cover of the container, the pack falls out of the orifice via a chute device into the microwave oven. The falling of the pack out of the container is recorded by a photocell which emits the pulse for closing and switching on the microwave oven. The time relay controls the heating time and emits the pulse for opening the door, and at the same time the dispensing mechanism is set in motion and dispenses the pack to the serving orifice.

Title: Electric-car drive battery storage by wind power
Inventor: MORSCHEL FRIEDRICH
IPC: F03D9/32
Filed: 1989-03-10
Abstract: Due to ever increasing motorisation and the associated consumption of mineral oil, within the foreseeable future the stocks of mineral oil in the world will be used up. About a third of the consumption of mineral oil goes through the car exhaust. In the future too the car will remain the main locomotion means on the roads. The drive of a vehicle in the future has therefore to satisfy two conditions: The drive should not be reliant only on oil or natural gas and, furthermore, in order to protect the environment, the drive should not directly or even indirectly produce any harmful exhaust emissions. The petrol drive is and remains problematical because of the exhaustion of the oil supplies and because of environmental pollution. Solutions which have been tried and tested already using oil as the propellant for internal combustion engines require coal, oil or natural gas as the primary energy for production. A better alternative is the increased use of electric motors as the driving system, i.e. the combination of electric motor and battery as energy store. An exhaust-emission-free drive. A disadvantage up to now has been the low range of the battery store due to lack of possibilities for recharging during the journey. A solution to this problem is possible by recovering the energy consumed by utilising the wind power of the head wind which is produced during and by the journey. This object is achieved by installing air ducts with incorporated ventilators. The invention is described and ... Original abstract incomplete.
