Title: Method of cultivating potatoes - involves planting parts of potato rather than whole seed using piece with eye and surrounding five millimetres of flesh
Inventor: UNGER RALPH GUENTER
IPC: A01G7/00

Title: Heated roll, in particular for packing-sheet calenders
Inventor: VOGEL ROLAND
IPC: B21B27/08
Filed: 1993-03-31
Abstract: The roll comprises a shell (1) with peripheral bores (2) for the heating medium and two ends (5; 40), each with a shaft journal (6; 41). The intention is to use little outlay to ensure the stability of the roll and permit exact controlling of the desired surface temperature while avoiding heat losses and fluctuations. Arranged in the central bore (12) of the one shaft journal (6) is an insulated feed pipe (13), from which feed channels, thermally insulated in the end (5), lead to the peripheral bores (2) in the roll shell (1). After heating the roll surface, the heating medium flows away, thermally insulated, via discharge channels in the other end (40). The outlet from the roll takes place, in any event thermally insulated, via the one or the other shaft journal (6; 41). In the case of discharge via the shaft journal (6), the discharge pipe (16) is surrounded, between the ends (5; 40), by an insulation (21) and in the shaft journal (6) by the insulating pipe (48), forming an air gap (49). Heated roll of relatively large diameter for packing-sheet calenders.   <IMAGE>

Title: Fuel element and place-keeper for fuel elements
Inventor: KRATZER ANTON DIPL ING
IPC: G21C3/326
Filed: 1993-08-05
Abstract: When fuel elements are removed, in order to be able to guide the guide elements of a boiling water reactor laterally, place-keeper elements are provided whose outer contour corresponds virtually to the outer contour of the replaced fuel element, the lower end of the place-keeper element, however, projecting further into a passage channel of the core grid structure than the replaced fuel element. Hence, if the place-holder element ("dummy") does not encounter the passage channel of the core grid structure, its upper edge then projects considerably beyond the upper edge of the fuel elements, which can be noticed immediately to correct the position of the dummy. According to the invention, false seating of the fuel element itself can also be detected optically, if the fuel element is extended beyond the foot by means of a pin projecting into the passage channel of the core grid. <IMAGE>

Title: Process and apparatus for welding thermoplastic pipe parts
Inventor: LUEGHAMER ALBERT
IPC: B29C65/14
Filed: 1993-09-01
Abstract: In the case of the proposed process and apparatus for welding tubular plastic parts, heated gas is applied to the welding region essentially radially in a locally defined area by means of a heating ring (3). Before the welding operation, the two pipe parts (1, 2) of thermoplastic which are to be connected to each other are aligned axially by means of an inner plug (4), the outside diameter of which can be adjusted in a defined way. After the softening of the pipe parts (1, 2) in the region of their abutting surfaces, they are pushed against each other on the inner plug (4) and joined together. After the setting of the weld, the outside diameter of the plastic plug can be reduced and the said plugs can be removed in a simple way from the pipe formed. <IMAGE>
