Title: 3-Amino-5-(pyridinyl)-2(1H)-pyridinones
IPC: C07D213/82
Filed: 1976-10-14
Abstract: Compounds useful as cardiotonic agents are 1-R-3-Q-5-PY-2(1H)-pyridinones (I) where R is hydrogen, lower-alkyl or lower-hydroxyalkyl, Q is amino (preferred), lower-alkylamino, di-(lower-alkyl)amino or NHAc, Ac is lower-alkanoyl or lower-carbalkoxy, and PY is 4- or 3- or 2-pyridinyl or 4- or 3- or 2-pyridinyl having one or two lower-alkyl substituents. The corresponding compounds where Q is nitro, carbamyl, cyano, halo or hydrogen are useful as intermediates and those where Q is hydrogen or cyano also are useful as cardiotonic agents. Said compounds are prepared: by reacting alpha -PY- beta -(R1R2N)acrolein (II) with malonamide to produce 1,2-dihydro-2-oxo-5-PY-nicotinamide (Ia) and reacting Ia with a reagent capable of converting carbamyl to amino to produce 3-amino-5-PY-2(1H)-pyridinone (Ib) by reacting II or alpha -PY-malonaldehyde (II') with alpha -cyanoacetamide to produce 1,2-dihydro-2-oxo-5-PY-nicotinonitrile (III) and partially hydrolyzing III to produce Ia and, by heating 1,2-dihydro-2-oxo-5-PY-nicotinic acid (IV) with a mixture of concentrated sulfuric acid and concentrated nitric acid to produce 3-nitro-5-PY-2(1H)-pyridinone (Ic) and then either reducing Ic to produce Ib or first reacting Ic with an alkylating agent to produce 1-R'-3-nitro-5-PY-2(1H)-pyridinone (Id) and reducing Id to produce 1-R'-3-amino-5-PY-2(1H)-pyridinone (Ib) where R' is lower-alkyl or lower-hydroxyalkyl. Other derivatives of I where Q is amino are shown.
Patent ES-458813-A1 (ES)
Title: Purification of waste water
IPC: C02F3/12
Filed: 1977-05-14
Abstract: A process for the treatment of effluent which contains solid, sedimentable, colloidal and truly dissolved substances and whose impurities are at least partially of an organic nature, with a reduction in the chemical and biochemical oxygen demand, is characterised in that flocculation aids are added to the effluent and the solids-containing effluent is passed by gravity through a supporting fabric located in a suspending device. During the filtration step, a combination filter composed of a) this supporting fabric and b) a primary filter layer of the solids separated off is formed, by means of which the further effluent introduced is freed of the major part of the solid particles. The filtration through this combination filter has the effect that not only the sedimentable and also a substantial part of the colloidally dissolved substances, but also a major part of the truly dissolved substances are separated off, so that a filtrate is obtained, for the treatment of which a biological oxygen demand is required which is reduced by up to 90 %, relative to a municipal effluent freed of solids. The process can be combined with equipment for biological and/or chemical-physical treatment. Equipment in which the process according to the invention is carried out is described.

Title: Coating booth for electrostatic application of pulverized materials
IPC: B05B15/12
Filed: 1978-11-22
Abstract: A coating booth for the electrostatic application of powdery materials onto workpieces.

Patent ES-489869-A1 (ES)
Title: Method for continual replacement of the rubber lining in a rotating mill
IPC: B02C17/22
Filed: 1980-03-13
Abstract: A method is described for sequential replacement of the lining in a rotating mill according to wear of the lining. Generally, such a lining consists of adjacent zones parallel to the rotational axis of the mill, the height of these zones varying periodically in the peripheral direction of the mill. According to the invention rubber beams of equal width are used, and for the replacement operation completely fresh beams of only one height are employed, this height representing the highest one of only a few preselected categories of beams. Upon removal of worn beams, these are reassorted according to the selected categories and those beams worn-out and unfit for even the lowest category are discarded. Thus, the reassorted beams not rejected can be reused properly positioned so as to maintain a suitable variation of the beam height in the peripheral direction of the mill, and only one height of fresh beams need to be held in stock. When replacing, the particular beam category may be retained at a certain beam position, or completely fresh beams may be inserted at positions of beams completely discarded, whereby the desired variation of beam height in the peripheral direction is obtained by suitable replacement or rearrangement of the remaining beams.

Title: Method of making sintered powder metallurgical bodies
IPC: B22F3/12
Filed: 1981-01-29
Abstract: A process for making sintered metal articles of high strength in which a flowable mass of metallic particles is initially formed into a green compact having shape stability in a forming machine of the type used in the fabrication of sand cores in the metal casting field. The green compact is then subjected to sintering and the sintered body may be pressed, forged or mechanically shaped in other ways. The core blowing or core-sand slinging machine used to produce the green metal compact is surprisingly effective in producing a dense, reproducible structure in light of the fact that sand cores for casting purposes are intentionally made frangible to enable them to be removed effectively from the casting.
