Patent ES-372055-A1 (ES)
Title: Process for the preparation of a salt of optically active lysine
IPC: C07C227/36
Filed: 1969-09-30
Abstract: A salt of an optical antipode of lysine with sulphanilio acid is produced by forming a supersaturated solution of a mixture of salts of the optical antipodes of lysine with sulphanilic acid, separating an optically active salt from the mixture by selective crystallization, and also racemising the non-desired optionally active salt of lysine and sulphanilic acid by heating an aqueous solution of the salt, e.g. at about 200 C. Crystallization may be effected by sealing, and both enantiomers may be obtained from successive crystallization operations also subsequent saturation of the mother liquor from the crystallization of one form with the racemic salt yields the other antipode. The optical purity of the lysine sulphanilate salt may be increased by treatment with a solvent, e.g. water or aqueous alcohols or ketones, which produces a solid phase of greater optical purity in contact with a saturated liquid phase. Optically active lysine is recovered from the sulphanilate salt, e.g. by use of ion-exchange resin techniques. Specification 1,191,100 is referred to.

Title: Heat store
IPC: F24S90/00
Filed: 1976-04-27
Abstract: In a shaped body which is bound by cross-linked plastic and serves as a heat accumulator, a heat exchanger is embedded in crystalline heat storage substance. The maximum operating temperature of the heat exchanger is higher than the melting temperature of the crystalline substance. Expediently, the cross-linked plastic at the same time serves as the crystalline substance this has the advantage that the solid state of aggregation is retained when the crystallites melt. A heat accumulator of this type can be employed as follows in a solar energy-harnessing installation: The heat accumulator (1) is interconnected with two solar energy absorbers (2, 3), two useful-heat exchangers (4, 5), two circulating pumps (6, 7) and various valves (8-11) to form two separate heat transfer fluid circuits. The heat accumulator (1) comprises two concentric blocks (13, 14) which are separated by an insulating layer (12) and are made of crystalline, cross-linked epoxy resin or polyurethane resin with crystallite melting temperatures of 45 DEG and 60 DEG C respectively. Embedded in the blocks (13, 14) there is one copper coil (16, 17) each, via which the heat exchange takes place between the circulating medium and the plastic blocks acting as latent-heat accumulators. The use of crystalline cross-linked plastic as the storage material permits a particularly expedient and straightforward construction of the heat exchanger.

Patent ES-8105446-A1 (ES)
Title: Ignition control system
IPC: F02P3/04
Filed: 1980-04-25
Abstract: An ignition control system typically used with an automobile engine provides tight feedback control on engine timing. An integrator produces a waveform which is typically dual-slope in response to a timing signal supplied by a sensor responsive to rotation of a distributor. A dwell-control circuit produces a dwell-control reference signal which varies with the integrator waveform voltage at low engine speed. A comparator generates an output drive-control signal when the integrator waveform voltage equals or is less than the dwell-control reference voltage. An output drive circuit produces an activation signal in response to the drive-control signal to activate an output drive circuit which then supplies an ignition signal to an ignition coil. A feedback loop between the output drive circuit and the output drive-control circuit causes the output drive circuit to stabilize at a selected state such as a specified output current level. A feedback loop between the output drive circuit and the dwell-control circuit controls the level of the dwell-control reference voltage and thereby controls the dwell period.
