Patent ES-485216-A1 (ES)
Title: Liquid feeding and mixing arrangement including a flow-shielding ejector thermal sleeve
IPC: G21C13/032
Filed: 1979-10-19
Abstract: An improved arrangement for feeding a cool liquid into a pressure vessel and mixing the fed liquid with hot liquid contained therein includes a flow-shielding ejector thermal sleeve disposed partially within an inlet nozzle and surrounding a supply line through which the main feed flow is conducted to a sparger outlet port in the vessel. The sleeve is spaced radially inwardly from the inner surface of the nozzle to define a generally annular flow-through space therebetween. Cool leakage liquid flow is confined within the sleeve and ejected by the main feed flow from an ejector chamber formed around the port by a downstream portion of the sleeve. The ejective action of the main flow exiting the port additionally draws an insulating flow of hot liquid from the vessel sequentially upstream through the flow-through space, into the interior of the upstream portion of the sleeve, and downstream with the confined cool leakage flow, thereby substantially reducing cracking of the nozzle.

Title: Coating polymerization reactors with oligomer coatings derived from reaction products of substituted phenols.
IPC: B05D7/24
Filed: 1979-10-23
Abstract: Polymerization reaction vessel having a coating on the inner surfaces thereof resulting from applying thereto a coating composition containing, as a primary ingredient, the reaction product or oligomers of (1) an alkyl or halogen substituted phenol, such as p-chlorophenol and the like, (2) a condensing agent, such as formaldehyde, and the like, and (3) a polyhydric phenol, such as resorcinol, and the like, dissolved in water or an aqueous alkaline solution. When polymerizing olefinic monomers, such as vinyl halides, vinylidene halides, and vinylidene monomers, having at least one terminal CH2=CH<group, and mixtures thereof, polymer buildup on the inner surfaces of the reaction vessel is substantially eliminated. Further, multiple charges or batches of polymer can be made in said internally coated reaction vessel without opening the same between charges thus preventing the escape of unreacted monomer (s) to the surrounding atmosphere.

Patent ES-8303758-A1 (ES)
Title: Improvements in and relating to testing coins.
IPC: G07D/
Filed: 1982-02-15
Abstract: A coin testing apparatus comprises transmitting and receiving coils (14) and (15) on opposite sides of a coin passageway (11). The transmitting coil is connected to high and low frequency oscillators (16) and (17). The output of the receiving coil is separated into the high and low frequency components by a high pass filter (21) and a band pass filter (22). In the high frequency channel the signal is amplitude controlled by a voltage controlled amplifier (23) rectified by a rectifier (24) and smoothed by a long time-constant circuit (26). The initial rise in level caused by a coin entering between the coils (14) and (15) is detected by an instantaneous level change comparator (32) which responds to the rate of change of signal level at the output of the long time-constant circuit (26) becoming equal to a preset threshold and causes a normally closed switch (27) to be opened. When the switch (27) is closed a comparator (31) compares the signal with a reference value from a source (30) and adjusts the gain of the amplifier (23) until the signal corresponds to the reference value. Upon the arrival of the coin the switch (27) is opened and a long time-constant circuit (28) causes the gain of the amplifier (23) to be maintained at the level before the arrival of the coin. A window comparator (33) compares the difference in voltage with voltage ranges for acceptable coins. A similar arrangement is provided in the low frequency channel but with two differences. The switch (27) in the low frequency channel is operated by the same instantaneous level comparator as is used for the high frequency channel and instead of a rectifier (24) a novel sample and hold technique is used for providing a d.c. signal from the output of the amplifier (23).

Title: A process for preparation of the thioester of N-acetyl- cysteine
IPC: A61K31/225
Filed: 1982-05-24
Abstract: The thioester of N-acetyl-cysteine with p-isobutylphenyl- propionic acid shows simultaneous anti-inflammatory and mucolytic activity. It is prepared by the reaction of a reactive derivative of p-isobutylphenylpropionic acid and N-acetyl-cysteine at low temperature in a polar solvent. Salts with organic and inorganic bases, with basic amino acids and with basic antibiotics which have a macromolecular structure are stable and generally soluble in water, as a result of which the active ingredient according to the invention can be formulated for oral, parenteral, rectal and topical administration. This invention relates to a thioester of N-acetyl- cysteine propionyl glycine with p-isobutylphenylpropionic acid, which has the formula: <IMAGE> and which has useful anti-inflammatory and mucolytic properties, and its pharmacologically acceptable non- toxic salts. The anti-inflammatory activity of p- isobutylphenylpropionic acid is known, and the disadvantages from the point of view of its therapeutic use are also known. The compound according to the invention, as such or converted into a salt with organic bases containing alkaline or alkaline earth ions, or with basic amino acids such as arginine and lysine, or with the nuclei of basic antibiotics such as erythromycin and propionyl erythromycin, demonstrate useful properties as they have anti-inflammatory and mucolytic activity at the same time. This invention also relates to processes for the preparation of the subject compound which are characterised in that a p-isobutylphenylpropionic acid halide and a derivative of N-acetyl-cysteine are caused to react in a medium which has an alkaline pH containing a polar solvent, preferably water or mixtures of water and dioxan, at low temperature, giving rise to a low melting point thioester which is an odourless pale yellow oil at ambient temperature. The reaction product as such is free from impurities and is used in the reaction to form the salt with the various bases mentioned above in order to obtain the corresponding salts, which are stable, water-soluble and easy to use in the pharmaceutical field.

Title: A method of detecting obnoxious taint such as boar taint in individual animal bodies, preferably carcasses or parts thereof.
IPC: G01N33/12
Filed: 1982-09-08
Abstract: PCT No. PCT/DK82/00080 Sec. 371 Date May 6, 1983 Sec. 102(e) Date May 6, 1983 PCT Filed Sep. 8, 1982 PCT Pub. No. WO83/00928 PCT Pub. Date Mar. 17, 1983.Boar taint in individual animal bodies, preferably carcasses or parts thereof, is detected by preparing an extract of a meat and/or fat sample from the body or part thereof, reacting said extract with a color reagent, for which the color intensity developed at certain wavelengths exhibit a statistical relationship with boar taint, determining the transmittance or absorbance of the reacted extract at one or more such wavelengths, and inserting the recorded values in the said statistical relationship. A high correlation has been found to exist between color reaction and boar taint evaluation so that the transmittance or absorbance at wave lengths characteristic of the color reaction gives a quantitative measure of boar taint intensity. This has made it possible to determine threshold values which objectively define organoleptic inacceptable taint levels. The method is fast and accurate and requires no extensive work in addition it has been possible to automatize it so that it can be used directly in connection with slaughter lines in slaughterhouses for industrial control and sorting of individual carcasses.
