Patent ES-337284-A1 (ES)
Title: Frequency modulation detector circuit suitable for integration in a monolithic semiconductor body
IPC: H03D3/10
Filed: 1967-02-25
Abstract: A frequency discriminator may include an integrated circuit chip 10 wherein the capacitors 68, 70 and 72 are reverse-biased diodes, and is characterized in that the time constant of load resistances 54 and 56 with capacitors 68 and 70 is of the same order as the period of the carrier wave. The short time constant reduces the harmonic content and reduces the load on transformer 36, as a result of which the waveform at the transformer is more nearly a sine wave. The load on the transformer may be further reduced by including further rectifiers 100 and 102 between rectifiers 50 and 52 and their associated load resistances, Fig. 5 (not shown). The capacitance in the discriminator load circuit may be increased by connecting two further diodes 90 and 92, Fig. 3 (not shown) in parallel with 68 and 70, the cathodes of these diodes being connected respectively to earth and to a positive 2 volt supply. The capacitance of diodes 90 and 92 is nearly twice that of diodes 68 and 70 due to the additional capacitance between their cathodes and the substrate of the integrated circuit. The similarly poled diodes 68 and 70 of Fig. 1 may be replaced by oppositely poled diodes 96 and 98, Fig. 4 (not shown). One of the diodes 98 then exhibits increased capacitance, for equal junction areas, and the junction areas are varied to compensate for this and for the different capacitances to earth exhibited by the anode of rectifier 50 and the cathode of rectifier 52. The method of construction of the integrated circuit is similar to that described in Specification 1,124,274.

Title: Process for recovery of glycidol from alcohol by azeotropic distillation with a hydrocarbon
IPC: C07C29/82
Filed: 1967-07-24
Abstract: Glycidol is recovered from a feed mixture comprising glycidol, allyl alcohol and higher boiling materials by conducting a first distillation of said feed mixture whereby a first overhead product and a first bottoms product are obtained, said first overhead product comprising allyl alcohol and said first bottoms product comprising glycidol substantially free from allyl alcohol, and conducting a second distillation, which is applied to the said first bottoms product, in the presence of a hydrocarbon azeotropic agent which forms a low boiling point azeotrope for the recovery, as a second overhead product, of a glycidol-azeotropic agent azeotrope. The glycidol azeotrope may be extracted with water to recover glycidol substantially free of the azeotropic agent in the form of a water solution of glycidol. Subsequently the water may be removed whereby substantially pure glycidol is obtained. The azeotropic agent is suitably a hydrocarbon and particularly useful are the aliphatic, naphthenic and aromatic hydrocarbons having the same skeletal carbon structure as the hydroperoxide employed in the epoxidation reaction wherein allyl alcohol is converted to glycidol. Those specified are ethylbenzene, cumene, benzene, toluene, pethyltoluene, isobutylbenzene, tetralin, diisopropylbenzene, xylenes, cyclohexane and alkylsubstituted cyclohexanes. In one embodiment, the distillation is conducted in the presence of a hydrocarbon azeotrope which forms a low-boiling azeotrope with glycidol, but which does not form an azeotrope with allyl alcohol, e.g. cumene, and in another embodiment the distillation is conducted in the presence of a hydrocarbon which forms two separate low boiling azeotropes, first with allyl alcohol and then with glycidol, e.g. ethylbenzene.

Title: Vapor compression evaporation with vent condenser and engine exhaust gas boiler
IPC: C02F1/18
Filed: 1968-01-26
Abstract: Liquid, e.g. salt water, is partly evaporated in chamber 31, the vapours are withdrawn from the chamber through pipe 49 by compressor 50, the compressed vapour is supplied through pipe 51 to the tube-bundle 55 wherein most of the vapour condenses and boils the salt water flowing over the outer surface of the tube-bundle, the residual vapour and non-condensable gases flow, together with the condensate, into a vent condenser 22, mounted in the manifold on the end of the tube-bundle, where the residual vapour is condensed by heat-exchange with salt water which passes through the tubes of condenser 22 before entering chamber 31. The manifold on the end of tube-bundle 55 is divided by a partition into an upper half and a lower half the upper half is connected by pipe 51 to the compressor, and the lower half houses the vent-condenser. Non-condensable gases are discharged from the condenser through pipe 57. Hot distillate, i.e. fresh water, is withdrawn from condenser 22 through pipe 56. Compressor 50 is driven by a diesel engine 14. Within chamber 31 is a supplementary boiler 70 comprising an open tank in which fresh water, circulated from and to the cooling jacket of engine 14 by pipes 78 and 76 respectively, is partly evaporated by means of exhaust gases from the engine which flow via pipe 74 through tubes in the open tank. The exhaust gases are then discharged through outlet 75. Some of the hot distillate flows from pipe 56 to the tank of boiler 70 whenever float 68 falls below a predetermined setting. Salt water is drawn into the system through strainer 12, and passes through heat exchanger 13 where it is preheated by lubricating oil circulated from engine 14. The water is then pumped through pipe 19 through plate-type heat exchanger 21 wherein it is heated by blow-down from sump 32 and by hot distillate from pipe 56. The salt water next flows through the tubes of condenser 22, and then through pipe 25 to pipe 27 where it mixes with some of the brine from sump 32. The mixture is then sprayed, through nozzles in tube 29, over tube bundle 55 in chamber 31. The pressure in chamber 31 is maintained constant by diaphragm valve 44 which admits cool salt water from pipe 20 into the chamber whenever the pressure rises above a predetermined value. Cool distillate is withdrawn from the system through valve 64.

Patent ES-361389-A1 (ES)
Title: Writing instrument
IPC: B43K24/10
Filed: 1968-12-13
Abstract: In a multiple, retractable writing instrument having a single push button 5 for rotating and sliding a drum 3 housing a plurality of cartridges, only a single compression spring 11 is provided for the projecting mechanism, which spring acts against the drum 3 biasing it rearwardly. The drum 3, (Fig. 10) has a first chamber 3a for slidable receiving the rear ends of the cartridges so that they are in tangential contact one with another. A cylindrical bore defines a second chamber 3b in the drum, an abutment or shoulder being formed between the two chambers. Into the rear end of each cartridge is inserted a cylindrical shank 12a of a sector shaped guide 12 provided with a shoulder 12c, which abuts the shoulder in the drum 3. Fastened to the push button 5 (Fig. 9 is a rod 4 which has one or several fingers (4a), which co-operate with notches (3d) in the top edge of the drum 3. With the drum 3 biased against the fingers (4a) by the spring 11, rotation of the push button 5 brings a selected cartridge into alignment with the eccentric opening 1a provided in the instrument barrel 1. A washer 7 fixed in the barrel also has notches (7a) which co-operate with the top edges of fingers (4a), thereby defining each angular position of the drum 3 to align each cartridge. An eccentric pusher 6 in which the rod 4 rotates, is fixed angularly with respect to the barrel and the washer 7, but slides through an eccentric hole (76) in the washer to contact the rear of the guide 12 of the selected cartridge when the pushbutton is depressed. When the selected cartridge is projected by depressing the button 5 (Fig. 11), the drum slides forward on the remaining non-selected cartridges which abut a shoulder 1b in the barrel 1. The cartridge is retained in the projected position by a known type of push-button actuated mechanism until the button 5 is again depressed and the drum 3 is released to be moved back by the spring 11. In an alternative embodiment (Figs. 14 and 15) the drum 3 is eliminated and the spring 11 acts as a single holding means for the cartridges which are bunched therein. The spring 11 is compressed between the shoulder 1c in the barrel and the shoulders 12c of the guides 12. Rotary movement is achieved with the fingers 4a inserted into the grooves (12d) formed between the guides 12.
