Title: System for grouping bottle cases into palletising sets - takes up three times three cases for further conveying and pushes rest to lateral intermediate store
IPC: B65G47/08
Filed: 1972-01-08
Granted: 1981-10-01
Abstract: The system forms groups of bottle cases or similar rectangular containers. They are conveyed in two rows, next to each other and grouped into complete layers suitable for palettising of three times three cases by a separating and grouping shaft. The complete layer formation (A) is separated from the block of four times three cases and consists of three times three cases moved in the direction of conveyor movement. The remaining group of once three cases is put into intermediate storage on one side outside the path of the conveyor for the remaining groups. These three cases are then combined with the thrid group of two times three cases to make up a second complete layer set (B) of three times three cases, which are then moved on in the direction of conveyor movement.

IPC: F23K5/00
Filed: 1981-06-09
Granted: 1985-03-14
Abstract: A process and an arrangement for the formation of an ignitable mixture from liquid fuel and combustion air, wherein preheated combustion air is conducted with a flow chamber along a surface which is moistened with fuel for take-up of fuel. In the process and arrangement, combustion air is conveyed into the flow chamber in the flow direction of the fuel which streams off the surface moistened by the fuel under the effect of gravity. Achieved hereby is an intensive contacting between the combustion air and the fuel. The fuel is dosed in excess so as to constantly afford a sufficient quantity of fuel for vaporization. During the through flow of the combustion air, there is formed, in the contact with the fuel, a saturated fuel-air mixture in conformance with the temperature of the preheated combustion air and the temperature of the fuel. Concurrently, care is taken that the trickling film of the fuel which is formed by gravitation as well as the drag effect exerted by the combustion air passing through the flow chamber can freely exit from the flow chamber at the foot of the surface moistened by fuel, to the extent in which the fuel is not taken up through vaporation by the combustion air in the flow chamber.

Abstract: A cylinder arrangement comprising two cylinders (3 and 4) which are parallel in respect of their axes of rotation (2) is used for consolidating fleece (1) in between them by means of heat and/or solvents. The two cylinders (3 and 4) have on their surfaces individual knobs (7 and 8) which are spaced apart and stand out relative to the actual cylinder surface (9 and 10). The knobs (7) on the one cylinder (3) fit between the knobs on the other cylinder and, in use, reach into the spaces between the knobs (8) on the other cylinder. The upper surfaces (5 and 6) of the knobs (7 and 8) on the cylinders (3 and 4) are close or very close to the smooth surface (9 and 10) of the opposite cylinder between the feet of the knobs thereon. Thus, the respective consolidation points (11) of the fleece (1) are mutually offset in height by the height of the knobs or the distance between the surfaces (9 and 10) of the cylinders (3 and 4).

Abstract: Solids are filtered from a fluid by supplying (12) the fluid to one end of a filter drum (3) with a perforated wall (8,9), rotating around the central axis (7) and at an angle to the horizontal. Some of the fluid passes through the wall. The drum has a fine filter on the interior. On rotation, the solids are caught in the filter material on the sieving wall and consolidated. By rotation and the action of the fluid, the solids are removed from the opposite end (20,22) relatively dry. Also claimed is a filter drum (3) used in the process described above, consisting of a cylindrical perforated wall with a filter material, a rotating system, fluid, e.g. liquids or gasses, supply and a solids outlet. The fine mesh filter material, woven or non-woven, is suitable for the purpose and is stretched (29- 31) on the inside of the drum. Also claimed is a cleaning system using the filter drum described above, for cleaning objects, e.g. textiles, with liquids or gasses, and then passing the liquid to the filter drum for filtering. The fluid is reused in a closed system.
