Patent ES-257224-A1 (ES)
Title: Process for the manufacture of metal chlorides
IPC: C01G1/06
Filed: 1960-04-08
Abstract: Aluminium chloride is prepared by reacting molten aluminium with chlorine, the chlorination and abstraction of heat liberated by the reaction being carried out in separate zones, and the molten aluminium is continuously circulated through the two zones. Molten aluminium 30 is contained in a cylindrical crucible 10 (Fig. 2), and chlorine is introduced through inlets 32. The contents of the crucible 10 are divided into a chlorination zone 40 and concentric cooling zone by a tubular member 34 supported on feet 35. Aluminium chloride vapour is produced in zone 40 and passes off through a collecting funnel 42 supported on lugs 36 attached to member 34, and is conveyed to a cooling chamber. The ascending aluminium <PICT:0937458/III/1> chloride vapour and the heat of chlorination cause the molten aluminium to ascend in zone 40 and to pass into the cooling zone between the member 34 and the walls of the crucible 10 as shown by arrows 38. Heat is lost through the walls of the crucible 10, the aluminium cools, descends and returns to the chlorination zone 40 as shown by arrows 39. Solid aluminium is introduced into the cooling zone to replace aluminium consumed, and any slag formed by reactions with impurities is removed from the cooling zone. A baffle 50 prevents metal spray being carried up by the aluminium chloride vapour. An example is given.

Title: Spray drying method
IPC: F26B3/12
Filed: 1967-05-26
Abstract: Food materials comprising solid components dissolved or dispersed in liquid are dried by spraying the material into a chamber which is supplied with a stream of drying gas, and collecting at least a portion of the partially-dried particles on a foraminous screen, the deposit of material being in porous form so that the drying gas can pass through the pores of the deposit and effect further drying.

Patent ES-390865-A1 (ES)
Title: Electronic flashlight units
IPC: H05B41/32
Filed: 1971-05-04
Abstract: In an electronic flashlight unit, a controlled semiconductor rectifier is ignited simultaneously with the ignition of flash tube and power from a first capacitor flows therethrough. A voltage of one polarity thereby appears across the rectifier. The discharge causes a voltage drop across a resistor and that voltage drop is used to charge an integrating capacitor in correspondence with the integral of the flash light flux as detected by a photoresistor. At a predetermined integral value a switching action applies the voltage of a quenching capacitor across the rectifier in a manner such that the polarity is opposite to said one polarity. The rectifier is thereby turned off to ensure that the flash tube is quenched. In one embodiment two semiconductor rectifiers each connected in series to a reactor are provided in the flash discharge circuit and a second pair similarly connected in the quenching circuit to enable the use of inexpensive low-power semiconductor rectifiers protected from overloading.

Title: Preparation and isolation of chloromethyl methyl ether by solvent extraction
IPC: C07C67/00
Filed: 1974-07-17
Abstract: An improved process has been developed for preparing chloromethyl methyl ether containing very low concentrations of bis(chloromethyl)ether. Methylal is saturated with hydrogen chloride under essentially anhydrous conditions to form an equilibrium mixture of chloromethyl mehtyl ether, methyl, hydrogen chloride and methanol containing less than 5 ppm bis(chloromethyl)ether. Then the chloromethyl methyl ether is recovered by selective solvent extraction, preferably with a liquid aliphatic hydrocarbon. Chloromethyl methyl ether thus prepared is used as an intermediate for preparing aromatic chloromethylated compounds.

Title: Device for sealing overwraps of packages
IPC: B65B51/00
Filed: 1975-06-30
Abstract: A device for controlling the sealing of seams of thermoplastic overwraps for packets of cigarettes. A wrapping wheel has a plurality of sealing stations for heat-sealing one single seam of the overwrap of each packet. In each station a heat-sealing contrivance can contact the seam during a halt of the wheel. The total contact time, that is, the sum of the individual times of contact between the several sealing contrivances and the overwrap, is controlled in response to the operating speed of the machine. For this purpose the several sealing contrivances, each connected for a reciprocating motion, are installed, one in each sealing station, and have a control system sensitive to variations in the operating speed of the machine, to trip the means for reciprocating them individually, to suit different speed levels of the machine.

Title: Method of recovering useful components by solvent extraction of multicomponent system nonferroussmetallcontaining solution
IPC: B01D15/04
Filed: 1977-04-05
Abstract: A multi-stage process is described for treating complex solns. contg. non-ferrous metals esp. Zn and Cu using existing plants e.g. mixing/decantation units and/or exchangers and a new type of cation exchange liq. and chelate former. The cation exchange liq. has, for all amine-forming non-ferrous metal cations, a capacity significantly different from zero and different fixing capacities for different cations. There is a large degree flexibility in the choice of starting materials. No other operating materials are required all the chemical prods. are in closed circuits. Only a corresponding pptg. agent e.g. lime or soda to ppte Zn from the residual aq. soln. is necessary since it is operated in closed circuit fewer pollution problems arise. Automatic operation is possible.
