Patent NL-1041599-A (NL)
Title: Device for removing weed.
Inventor: HENDRIKUS PETRUS VAN MOURIK
IPC: A01B1/16
Filed: 2015-11-26
Abstract: The invention comprises a device for removing a soil plug. The device is comprised of a piece of tube, which has preferably a perpendicular cut-off at the bottom end. The edges of the bottom end are preferably sharpened. A section of the wall of the tube is cut out at a certain distance of the bottom end, in order to allow the soil plug to escape or be removed. The cutout area is wider near the bottom end than further down upwards across the tube, resulting in a cross-section which is tapered at one side. The slanted shape allows the user to access the removed plug and at the same time guides a first removed plug outwards of the tube as soon as the device is inserted into a new piece of soil for removal of a second plug.

Title: Treatment of waste water from cracking units - by extraction with C6 raffinate before biological treatment
IPC: C02F1/26
Filed: 1974-05-22
Abstract: Waste waters contg. oily substances from naphtha cracking units are treated by (a) extracting the waste water with the 6C raffinate from the benzene recovery circuit of the cracking unit; (b) stripping the extracted waste water with air; (c) recycling the extract and the extraction solvent recovered in (b) back to the cracking unit; and (d) passing the treated waste water to a biological treatment unit.

Title: Folding end frame for flat bed conveyor - has tension spring extended in down position which contracts as frame is raised
IPC: B65D88/12
Filed: 1976-04-21
Abstract: The end frame (16, 16b) is joined to the conveyor (10) by pivot (18, 22). A side plate (14) on the conveyor provides a location (34) for one end of a long tension spring (33), the other end (31) being held in a block (32) fixed inside the end frame. In the folded down position, this spring is extended, due to eccentricity between pivot pin and spring mountings. When the end frame swings upwards, the top spring mounting in the block moves into line with the pivot. This shortens the distance between them and the spring contracts the energy expended reduces the effort required for raising the frame.

Title: Low loader railway wagon for transporting semi-trailers - carries turntable for each semi-trailer for direct unloading by traction vehicle (PT 14.1.81)
IPC: E01C9/06
Filed: 1981-04-16
Abstract: The deep loader railway wagon has low level chassis portions alternating with double axled bogies (50) so that a number of semi-trailers (16) can be carried, one behind the other in line. A turntable (24) is mounted between each pair of bogies. During travel, all the turntables are locked in position, each supporting a semi-trailer. On arrivel at a discharge point, the turntables can be swung about a vertical axis (56) so as to extend at an angle from the wagon for unloading..
