Patent ES-267532-A1 (ES)
Title: Pharmaceuticals with delayed release
IPC: A61K9/20
Filed: 1961-05-20
Abstract: A sustained and/or delayed release pharmaceutical tablet comprises a solid medicinally active substance, e.g. a solid "drug" or a drug admixed with a solid carrier in admixture with and/or coated with a water-insoluble copolymer of an olefinically unsaturated carboxylic acid monomer (e.g. acrylic acid) cross-linked with from 1 to 2% of a polyalkenyl polyether, e.g. "Carbopol" (Registered Trade Mark) 934. Mixing the polymer and drug and pressing into a tablet (optionally after slugging and grinding) gives a sustained release tablet which may be coated with the polymer to give an enteric tablet with sustained release. Coating a conventional tablet core with the polymer gives an enteric tablet. Suitable drugs which are preferably an acid or a salt are analgesics, antispasmodics, hypertensive agents, muscle relaxants, ataractics, antibiotics, anticonvulsants, antihistamines, coronary and peripheral vasodilators, fungistatic agents, antinauseants, central nervous system stimulants, parasympathetic inhibitors, antipruritics and phenothiazine compounds, specific examples being: mephentermine sulphate, promazine hydrochloride, potassium phenoxymethyl penicillin, ergotamine tartrate, acetylsalicylic acid, sodium salicylate and aminophylline.

Title: Method and apparatus for controlling the temperature of vapor created in a vapor generator
IPC: F22G5/20
Filed: 1964-02-06
Abstract: In a method for controlling the temperature of vapour generated in a forced flow vapour generator operating at subcritical or supercritical pressure and having a number of subcircuits (14) each with tubes connected in parallel, the rate of flow of liquid to each subcircuit is initially adjusted so that the rate of heat absorption in each is substantially uniform, and the rate of heat absorption in each subcircuit then being sensed to obtain a mean overall rate and then being simultaneously controlled in response to the sensed mean rate. Line (30) supplies feedwater to header (22) which supplies headers (16) of each subcircuit and also header (34) of control tubes (32). One tube (32) accompanies each subcircuit (14). At the beginning of the process thermocouples sense the heat absorped in each subcircuit and valves (26) are adjusted to make this uniform. The line (42) leads from common outlet header (40) of the control tubes to an outlet header of the subcircuits and is also connected to a temperature sensing device (44) controlling a device which operates either feedwater valve (28) or fuel valve (50). Valve (38) is adjusted to ensure the superheating of steam in the final portions of tubes (32).

Patent ES-341299-A1 (ES)
Title: A Method of Producing Gases Rich in Methane
IPC: C01B3/50
Filed: 1967-06-02
Abstract: In a method of making methane-rich gases by catalytically cracking hydrocarbons having a maximum B.P. of 350 C. with steam in the presence of hydrogen, the reactants are preheated to not more than 350 C. and then passed over a hydrogenating cracking catalyst, e.g. Ni or Co on an alumina or magnesium-aluminium silicate carrier. The catalyst may include 0-01 to 0-1% Pt or Pd, and the hydrogen may be obtained by recycling some product gas, or by delivering coke oven gas or refinery gas to the reaction. Preheating of the reactants is mainly by heat exchange with the product gas, and in one embodiment, see figure (not shown) petrol is heated to 160 C., mixed with hydrogen and heated to 330 to 350 C. and then mixed with super-heated steam at 27 atmospheres pressure. The method enables higher boiling hydrocarbons having an average of 10 to 25 C atoms per molecule, e.g. diesel and fuel oils, to be gasified without the formation of soot.

Filed: 1968-07-31
Abstract: In a process for oxidising saturated hydrocarbons (see Division C2), part of the liquid phase is continuously withdrawn and reinjected as stirring liquid from at least one injection point with a direction which imparts rotational movement to the liquid phase. The charge is introduced through duct 14 into vertical tower 1 which has a conical bottom terminating with outlet duct 2 for liquid products, duct 3, conveying an O 2 -containing gas, e.g. air, preferably terminates in a perforated ring distributor the holes of which are oriented towards the bottom of 1 (or to avoid the ring, the gas may be injected through holes in the conical base by a device not shown), the liquid outflow from 2 is aspirated by pump P and forced through four diametrically opposed pairs of stirring ducts 4, 5, 6, 7 which may be narrowed to injection nozzles and which are oriented tangentially to the column walls so as to wash them. Alternatively, these may be used 6 stirring ducts conveying the liquid at different levels and opening into 1 at angular intervals of 120 from each other. Duct 7 is preferably close to the liquid-gas interface 9 and at least the majority of the ducts are oriented to impart to the liquid as a whole a rotational movement in one direction about a vertical axis. Duct 10 is for evacuating residual gases and duct 11 conveys the liquid hydrocarbon for washing the gases into cup 12 from which liquid overflows onto the outside of upturned funnel 13, so that the escaping gases are scrubbed by a continuous screen of washing liquid.

Title: Air control damper for evaporative heat exchangers
IPC: F28F25/10
Filed: 1969-02-21
Abstract: In an evaporative heat exchanger, e.g. a cooling tower, wherein water to be cooled flows downwardly from a plurality of nozzles 22, through a heat exchange region 11, to be collected in a V-shaped sump 13, a damper 34 is provided in the housing of a centrifugal blower 17 to control the amount of cooling air supplied to the heat exchanger.

Patent ES-465171-A1 (ES)
Title: Method and arrangement for transfer of data information to two parallelly working computer means
IPC: G06F15/16
Filed: 1977-12-16
Abstract: Data information units are registered sequentially preparatory for transfer to two computer means, each by parallel-synchronous cooperation executing one of two accordant instruction sequences. The execution of each instruction sequence is divided in numbered periods which because of demanded information transfers comprise only one information transfer each. The demand for a transfer leads to a transfer number which is established by means of the period number obtained if the computer means execute instructions belonging to corresponding periods, and by means of the higher of the two period numbers if the instructions executed at the same time do not belong to corresponding periods. A transfer signal is transmitted to one of the computer means when the associated period number is equal to the transfer number. Due to a received transfer signal, the registered data information is transferred to the respective computer means. Thus the accordance of both instruction sequences is maintained in spite of a time displacement between corresponding periods.
