Title: Shell gene sorting of oil palm batches with shell mutation polymorphic marker assays
Inventor: Nathan D LAKEY
IPC: A01H1/04
Filed: 2018-07-23
Abstract: A process for cultivating a batch of oil palm seed or seedlings having a desired fruit form purity rate is provided. The process includes providing a purity rate of the desired fruit form, selected from either tenera, dura or pisifera, of the primary batch of seed or seedlings, which is derived from a secondary test batch of seed or seedling, such that the purity rate of the desired fruit form of the secondary test batch of seed or seedlings is based on the genotype of a SHELL Mutation polymorphism in each seed or seedling in the secondary test batch of seeds or seedlings. The primary batch of seed or seedlings is then cultivated if the purity rate of the desired fruit form of the primary batch of seed or seedlings meets or exceeds a cut off value.

Title: Method and arrangement for determining visibility
IPC: G01W1/00
Filed: 1994-03-30
Granted: 1996-08-26
Abstract: In order to determine the visibility, a light/dark contrast, which is formed by a number of groups of at least two stripes, is imaged by a video camera at a predefined distance. The electric image signals supplied by the video camera are compared with a threshold value set to a specific grey value and it is established whether or not the image signals reach the level of the threshold value. The image signals which reach the level of the threshold value are counted and compared with the number of stripes and conclusions about the visibility are drawn from the difference between the counted image signals and the number of stripes on the object. <IMAGE>

Title: Cationic film-forming binders containing catalysts, processes for preparing them, and use thereof
Inventor: SCHIPFER RUDOLF DR
IPC: C09D133/06
Filed: 1992-05-29
Granted: 1994-07-25
Abstract: The invention relates to cationic film-forming binders which contain catalysts, are water-dilutable following protonization, and comprise bismuth salts of aliphatic hydroxycarboxylic acids. Particularly suitable bismuth salts are those of lactic acid and of dimethylolpropionic acid, the bismuth content, based on the solids content of the film-forming binder, being from 0.1 to 5.0% by weight. Cathodically depositable deposition-coating materials based on these binders have excellent application and film properties. It is therefore possible to dispense with the use of lead compounds and tin compounds as catalysts.

Abstract: Normally, an ejection nozzle with apistol grip valve and two nozzle tubes protuding from there to a narrow high-pressure nozzle and a wide low-pressure nozzle are used for high-pressure cleaning units. In the tube leading to the low-pressure nozzle, a shut-off valve is provided, said nozzle being closed when spraying through the ejection nozzle. In the invention, both the two nozzles and the shut-off valve are incorporated in a single nozzle unit, which only requires a single inlet tube (2). This tube terminates in a high-pressure nozzle opening (10), but a wide side duct (12) is provided in front of this opening, said duct feeding the water out to an annular chamber, from where it can flow out through an annular outlet (60) around the high-pressure nozzle after an operational sliding movement of the external cylindrical part (6) proper of the nozzle unit. Around and in front of the annular outlet (60), a cylindrical jacket is disposed, said jacket having a transverse wall (26) forwardly spaced from the high-pressure nozzle (10). In the said wall, a wider ejection opening (44) is provided coaxially with it, said opening constituting the low-pressure nozzle. In shifting the cylindrical part (6) the opposite way, the annular outlet (60) is closed, so that ejection only takes place through the high-pressure nozzle (10) out through the wider low-pressure nozzle opening (44). The cylindrical part (6) has an external rotatable jacket (54) which is controllably connected with a couple of lip plates (46) placed in front of the low-pressure nozzle, said plates acting so as to impart a fan shape to the ejected jet, so that the cylindrical part (6) can moreover be operated for adjusting the fan width of the jet.
