Patent NL-2018076-A (NL)
Title: A plate-shaped structure, a reservoir and a method
Inventor: PETRUS MATTHEUS MARIA HOFF
IPC: A01G27/02
Filed: 2016-12-23
Abstract: The invention relates to a plate-shaped structure for cultivating one or more plants. The plate-shaped structure may optionally collect moisture from the atmosphere and comprises a generally flat upper surface provided with a cavity for holding plant material.

Title: Stop apparatus for delimiting a beam path between a light source and an illumination optical unit of a projection exposure apparatus for projection lithography
Inventor: MICHAEL PATRA
IPC: G03F7/20
Filed: 2021-09-21
Abstract: A stop apparatus (3 6) serves to delimit an illumination light beam path between a light source and an illumination optical unit of a projection exposure apparatus for projection lithography. The stop apparatus (3 6) has a stop (35) which is arranged in the beam path and which has an aperture (34) for the passage of used illumination light (16) that emanates from the light source. At least one displacement device (47) serves to displace the stop (35) transversely to the illumination light beam path. This yields a stop apparatus, the use of which yields an increased EUV throughput of a projection exposure apparatus equipped therewith in the case of an otherwise comparable imaging and structuring performance of the projection exposure apparatus, or an improved structuring and imaging performance at a given EUV throughput.

IPC: C09C1/02
Filed: 1964-10-28
Abstract: The degree of whiteness of a mineral carbonate containing humic acids which are organic colour-imparting impurities is improved by treating the carbonate at 20-100 DEG  C. with a halogen, an oxygen-containing halogen acid, or a salt thereof, e.g. HOCl, HClO4, CaOCl2, CaCl2, NaOCl, or ozone, or oxidizing agents in alkaline media, e.g. H2O2, Cl2, Br2, or transforming into a soluble form, e.g. by a salt of phosphoric acid or a polyphosphoric acid.  The degree of whiteness of all mineral carbonate fillers, e.g. calcite, dolomite and chalk, can be improved.  Treatment may be carried out in an aqueous medium, thereafter separating the carbonate, washing and drying it.

Patent NL-7310194-A (NL)
Title: Surgical drain eccentric locking mechanism - has male and female portions with bores eccentric to instrument axis
IPC: A61M25/02
Filed: 1973-07-20
Abstract: The mechanism is particularly for use with a catheter inserted in a body cavity, and comprises a pair of safety devices mounted on the oblong body, one with a protruding male portion and the other having a hollow portion in which it fits. The male and female portions can be rotated in relation to each other, each having a circular through passage concentric to the other through which the portion is inserted to secure the device on the body. However the passages are eccentric to the centre line of the male portion and the hollow body, so that the safety devices cannot turn right round it. When one of them is rotated, the body and the passage walls are forced into frictional contact, thus preventing displacement.

Patent NL-7407005-A (NL)
Title: Detachable chain locking mechanism - has lever in chain trough with pivoting fork catch engaging in trough recesses
IPC: B63B21/08
Filed: 1974-05-24
Abstract: The chain runs through a trough, between the walls of which there hinges a lever (16). On the lever a fork-shaped catch (11) hinges at a point distant from the lever axis (17), and the fork prongs when in the locked position fit over an upright chain link in the trough, engaging in recesses formed in the latter. The distance between the lever axis and the bottom of the recess can be less than the sum of the distance between lever and catch (22) axis and the effective length of the catch, giving a toggle locking action, since the catch axis cannot go past the line joining lever axis and recess. The recesses can be formed in two chain guides, separated by a groove, in the bottom of the trough at the sides. The chain may be used for marine towing work.

Title: Barrel-shaped synthetic material crate for bottles, etc. - has stave shape corner profiles making adequately strong thin walls permissible
IPC: B65D25/28
Filed: 1977-12-30
Abstract: A crate of synthetic material having a bottom and standing walls with corner profiles and bottle supporting elements, eliminates the problems of these containers. In conventional crates uneven or undersize walls deflect badly, whilst thicker walls, apart from using much more material have the disadvantages of slower prodn. times and built in temp. stresses which shorten their life. The circumference of the cross-section of this crate, increases from the top edge downwards to a maximal value and then diminishes again towards the bottom. The corner profiles have the form of barrel staves, and with these thinner walls can be used without stiffening ribs.
Patent NL-7805984-A (NL)
Title: Transporting prefabricated pipeline sections and laying on the sea-bed - using submerged carrying pipe with adjustable ballast to suspend during transport and lower pipeline section
IPC: F16L1/16
Filed: 1978-06-01
Abstract: Underwater pipeline is prefabricated to a selected length and then transported to its location and sunk to the seabed. During the transport, the pipeline section is suspended from a submerged carrying pipe with adjustable ballast so that the depth of the assembly can be adjusted to be without the range of influence of surface waves. Once at the location, the pipe and carrying pipe is lowered to the seabed by increasing the ballast of the carrying assembly after which, the latter is removed. The final positioning of the pipeline section takes place by allowing the pipeline to just touch the seabed until the correct position has been attained and then allowing its full weight to rest on the bottom. The length of the transporting pipe is equal to or greater than the length of the pipeline section. The transport depth can be gauged by means of depth gauges attached to the carrier pipe and protruding above the water surface. The assembly is preferably towed by means of a submarine or a towboat linked to the carrier pipe via cable and an intermediate sinker whose weight counterbalance the upward force of the two cable so that the carrier is only subjected to a horizontal force. Transport system enables large pipe sections to be prefabricated in shallow, calm waters and then transported to location eliminating much of the deep water fabrication work. The submerged carrier prevents the pipeline section from being damaged by surface wave conditions during transit.
