Title: Consolidation of subterranean formations - by injection of a resin soln. contg. inert solids and soluble solids
IPC: E21B43/04
Filed: 1976-02-20
Abstract: Incompetent subterranean formations are consolidated by (a) dispersing a resin in a carrier liq.; (b) adding a mixt. of inert solids coated with the resin and uncoated solid particles comprising a mixt. of hdyrocarbon wax and a polymer, the wax/polymer particles being insoluble in the carrier liq. at ambient temp. but oil-soluble at the formation temp; (c) injecting the resulting mixt. into the annular space between the formation and a gravel-packing solids retainer; (d) hardening the resin; and (e) dissolving the wax/polymer particles. The process produces a highly permeable hard solid mass which controls loose sands in oil-, water- and gas-bearing formations without significant loss of permeability.

Title: Urea prodn. from ammonia and carbon di:oxide - with vacuum thickening of urea soln. and passing uncondensed vapour from this stage through cooling agent-absorbent
IPC: C07C273/04
Filed: 1980-02-05
Abstract: Urea is made by reacting ammonia and carbon dioxide at 140-400 ata/160-230 deg.C. The resulting aq. soln. of urea is sepd. from unreacted NH3 and CO2 (stage 1). Liq. or gaseous streams of NH3 and CO2 are sepd. from gases inert to the synthesis of urea and from the purified waste water withdrawn from the process (stage 2); and these sepd. streams are recycled to the synthesis process. The recovered urea soln. is vacuum thickened (stage 3) at 0.04-0.90 ata to give a condensed phase of dehydrated urea and a vapour phase which is a mixt. of water, NH3, CO2 and urea. The dehydrated urea is converted into solid particles and cooled in an airstream; and urea dust is water-washed from the resulting air to form an aq. soln. of urea which is delivered to stage 3. The mixt. of water, NH3, CO2 and urea from the vapour phase of stage 3 is condensed due to its indirect cooling, to form a liquor vapour condensate which is supplied to stage 2. NH3 and CO2 contained in the uncondensed portion of the vapour phase after the indirect cooling are directly contacted with a cooling agent-absorbent at 10-60 deg.C/1.5-18 ata which contains dissolved in water 0.2-3.4 wt.% NH3, 0-1 wt.% CO2 and 0-50% urea; and at least a portion of the resulting soln. is then passed to stage 1, stage 2 or stage 3. The process makes it possible to avoid supplying power steam to the zone of contacting with the vapour-gas stream remaining after completion of the liquor vapour condensation due to indirect cooling (cf. conventional Mitsui Toatsu (FR2099882) or Stamicarbon (FR1184991) processes). Urea is used in mfr. of fertilisers, protein additives for ruminant feedstuffs, resins, etc.

Title: Prepn. of N-acyl tryptamine derivs. - by reacting carboxylic acid with alkyl chloroformate and then with tryptamine cpd.
IPC: C07D209/28
Filed: 1981-11-13
Abstract: Prepn. of N-acyl tryptamine derivs. of formula (I) is carried out by reacting a carboxylic acid of formula R3COOH (II) with an alkyl chloroformate in the presence of triethylamine, adding a tryptamine cpd. of formula (III) or an acid-addn. salt of (III) and triethylamine, and isolating (I) and opt. converting it to a nontoxic salt (where R1 is H or MeO; R2 is H or Me; R3 is pyridyl, iodomethylpyridyl, chloromethylpyridyl or 1-(p-chlorobenzoyl)-5-methoxy-2-methyl-3-indolylmethyl). The calimed process includes the use of trimethoxybenzoic acid as (II) (prepn. of N-3,4,5-trimethoxybenzoyltryptamine is disclosed), and the halomethylpyridine derivs. are disclosed as being pyridine methohalide derivs. Cpds.

The transformer has two secondaries, one of which (3) is connected between earth and a variable capacitor (6), the other side of the capacitor being connected to the input of a 'lock-in' amplifier (7). The other sec. (4) is connected between earth and one of the concentric detector probes (5). The other probe electrode is linked to the amplifier input. The outer connections of the probe assembly can be cooled by forced water circulation.

Title: System for preparing rotary silk-screen printing stencil for printing - involves application of photosensitive coating, drying, pattern-wise exposure, development and hardening
IPC: B41C1/14
Filed: 1988-04-16
Abstract: The process comprises the steps of applying a patterned sealing coating to the stencil and fixing end rings in the stencil in order to be able to incorporate it in a printing machine. Starting from an uncoated stencil, the end rings are first fixed and the patterned sealing coating is then formed by coating the stencil with a layer of a suitable photographic lacquer, drying and patterned exposure thereof and developing and hardening. The end rings (7;32) greatest external diameter is smaller than the external diameter of the stencil in question are used. For the application of the coat of photographic lacquer the stencil is accommodated between two suporting rings (21), which can each accommodate an end (7;32) at one end on the inside.
