Title: Delivering groups of articles to packing machine - has e.g. bread rolls moving in parallel rows divided into groups, which are lifted onto feed conveyor and placed on preceding group
Inventor: DAHL KRAG ERNST
IPC: B65B35/52
Filed: 1991-06-07
Abstract: The articles are fed onto a conveyor belt, and move in two or more parallel rows to a collecting surface into which they are fed with an equal number of articles in each row, thus forming a horizontal array. Further articles move in two or more further rows to a further similar collecting surface in which a similar horizontal array of articles is formed. The first array is then moved as a unit by a transport mechanism onto the packing machine feed conveyor, and moves forward so that the second array is moved as a unit by a second transport mechanism and is placed on top of the first array. In the case of articles which have distinct upper and lower surfaces, the first transport mechanism may be used to invert the first array, so that the packed articles have all of the upper surfaces of the articles on the outside. This may be achieved by a transport mechanism which is provided with a means for gripping the undersides of the articles. USE/ADVANTAGE - Used for arranging and packing groups of articles such as bread rolls in more than one layer. The packing process is made fully automatic, and the system is suitable for installation in industrial bakeries where the product comes in parallel rows from a tunnel oven. In particular, layers of articles can be packed so that the upper sides of the articles are facing towards the top and bottom surfaces of each package.

Title: Removal of weeds from cultivated ground - by marking cultivated plants with radioactive isotopes which can be detected by the mechanism and hence are not removed
Inventor: GERHARDS ALFRED DIPL ING
IPC: A01M21/00
Filed: 1991-11-21
Abstract: To mechanically clear weeds from cultivated ground, the cultivated plants carry markings which can be detected by sensors.

IPC: B67C3/10
Filed: 1992-04-25
Abstract: In a method and/or an apparatus for filling bottles or similar containers, the containers are rinsed out and preloaded with an inert gas in a preloading phase which precedes the filling phase.
