Patent NL-2024239-A (NL)
Title: Substrate support, lithographic apparatus, method for manipulating charge distribution and method for preparing a substrate
Inventor: KOEN GERHARDUS WINKELS
IPC: G03F7/20
Filed: 2019-11-14
Abstract: A substrate support is configured to support a substrate. The substrate support comprises a plurality of burls protruding from a base surface of the substrate support. The burls have distal ends in a plane for supporting a lower surface of the substrate with a gap between the base surface of the substrate support and the lower surface of the substrate. The substrate support comprises a liquid supply channel for supplying a conductive liquid to the gap so as to bridge the gap between the base surface of the substrate support and the lower surface of the substrate, thereby allowing charge to pass between the substrate support and the substrate. The substrate support has a controlled electrical potential such that charge distribution at the lower surface of the substrate can be manipulated.

Title: Determination of chloro-methyl methyl ether - by reacting with alkali metal salt of hydroxy compound, chromatographing and detecting
IPC: G01N31/00
Filed: 1974-07-22
Abstract: Presence of chloromethyl methyl ether (I) or bis-(chloromethyl) ether (II) in a fluid is determined by (a) reacting (I) or (II) with (III) an alkali metal salt of a 1-4 alcohol, phenol, alkoxyphenol, alkylphenol, chlorophenol, bromophenol, chloropyridinol, or chlorothiophenol, this salt being dissolved in a 1-4C alcohol, (b) passing the reaction prod. through a gas chromatographic column, (c) passing the eluted components thorugh a detector, and (d) presenting the outout from this detector on a reading device.

Patent NL-7511654-A (NL)
Title: High temp. reactor - uses radiant heat supplied to porous reactor tube
IPC: C01B31/08
Filed: 1975-10-03
Abstract: High temp. reactor e.g. for pyrolysis, decomposition and combustion reactions of organic and inorganic cpds. in which all the heat is supplied by radiation coupling comprises a reactor tube of porous refractory material capable of emitting radiant energy. Inert fluid is directed under press. through the porous tube wall to provide a protective blanket for the inside of the reactor tube. Reactants are directed in a predetermined path axially of the reactor tube and confined by the protective blanket within the central part of the tube. A heat shield directs radiant energy from an electric radiant energy source into the reactor tube to coincide with the path of the reactants. Since heat is supplied by radiation coupling the temp. of the reactant stream is independent of the temp. of the walls of the reactor tube. The tube therefore does not have to be made of material capable of withstanding the high temp. to which the reactant stream is subjected. The protective inert fluid blanket isolates the wall of the reactor tube from the reactant stream and prevents clogging by the accumulation of precipitates and deposits.

Title: Products from petroleum distillates and extracts - by air blowing followed by fractionation
IPC: C10G27/00
Filed: 1975-11-07
Abstract: Prods. are obtd. from petroleum distillates and/or solvent extracts of petroleum distillates having a viscosity-gravity constant (VGC, ASTM D 2140) of >0.85 (pref. >0.90) by blowing with O2 (pref. as air) and fractionating to recover at least one fraction boiling in the 320-420 degrees C range at a pressure of 760 mm Hg. The process can be used to produce a light "treatment oil" with high oxidative stability (b.p. 320-375 degrees C), a mid-range "treatment oil" (b.p. 375-420 degrees C), and a heavy fraction with an initial b.p. of >=400 degrees C for use as an additive for gramophone disc moulding compsns., giving an increased rate of prodn. and better sound reproduction. The initial distillate or extract is suitably a lube oil distillate or extract with an av. mol. wt. of 150-600 (pref. 200-500). Air blowing is pref. effected in the presence of 0.01-2 wt% of Cr, Co, Ni, Fe, Cu, Mn or Zn in the form of an oxide or an org. salt (pref. a naphthenate, acetate, propionate or butyrate), pref. for >=7 hr. The org. matl. entrained in the off-gas is pref. condensed and recycled. The above three fractions can be recovered from the same fractionation column, but are pref. recovered from separate operations, each preceded by air blowing.

Process requires only a small amt. of (II). Uniform charging of (I) in the image suspension is obtd. with no formation of deposits on the electrodes. Reproducible formation of good quality images with a good density and colour balance is provided.

IPC: G01L5/00
Filed: 1978-12-01
Abstract: Apparatus for continuous casting has pairs of rolls defining a path for the solidifying slab of steel. Between the rolls on each side are rows of spray nozzles.
