Title: Process for the Production of Oxalic Acid.
IPC: C07C51/275
Filed: 1967-03-17
Abstract: Oxalic acid is prepared by oxidizing propylene by introducing to nitric acid at 10 to 40 C. and heating to 45 to 100 C., with the simultaneous removal of the nitrogen oxides. The nitric acid concentration in the solution is maintained in the range 50 to 75% by weight, and the molar ratio of propylene to 100% nitric acid maintained throughout at between 0À01 to 1 and 0À5 to 1. Oxygen or oxygen containing gas may be introduced before or during either heating stage, and an elevated pressure may be employed.

Patent ES-341614-A1 (ES)
Title: Improvements in and relating to thermo copying apparatus
IPC: B41L19/00
Filed: 1967-06-09
Abstract: In a thermographic copying apparatus, sheets are inserted in a guide slot 32 and pass between a rotating glass cylinder 18, within which there is an infrared heater 31, and a resilient pressure roller 17 which is urged by springs 28, 29 into contact with the cylinder which is rotated by an adjustable friction drive. As the sheets are inserted, they engage a switch 33 which stops a motor driven blower 4 until each sheet has passed between the cylinder and the roller 17. The speed of the cylinder is varied by adjusting a wheel 40 so as to move a rack 42 axially. The rack 42 is either rigid with the drive motor 2 which is mounted on a support shaft 44 as shown, or else is an axial extension of the support shaft, Fig. 4 (not shown). This moves the motor 2 axially and hence a friction cone 6, rigidly mounted on a motor driven shaft 5 assumes a new adjusted position upon a friction disc 8 which is rigid with a worm shaft 7. The shaft 7 drives a roller 11 which in turn drives the cylinder 18. The motor 2 is pivotable about the support shaft 44 and is pivoted by a torsion spring 46 to maintain the cone 6 and disc 8 in contact, independently of the position or axial movement of the rack 42.

Patent ES-350967-A1 (ES)
Title: Apparatus for modifying a property of an article by diffusion
IPC: C03C21/00
Filed: 1968-02-26
Abstract: A physical and/or chemical property of glass or vitrocrystalline material is modified by a diffusion of ions, into such material, in exchange for other ions, at least at one surface of the material from a bath of liquid medium, while such surface is in contact with or adjacent to a screen or wall which shelters a quantity or quantities of liquid medium in contact with the surface from haphazard disturbance by random currents in the bath. The chemical tempering process particularly involves an exchange of alkali metal ions. If a glass sheet being treated is vertical then steady vertical currents occur in the liquid medium which are undisturbed by lateral currents and the concentration gradient can be predetermined. The steady currents can be strengthened by pumping or by superimposing thermal convection currents, or for descending currents by a cooling action. A perforate or porous screen, e.g. a refractory fabric, may be used as the wall. An imperforate screen, e.g. a corrugated wall or a wall shaped to define with the article surface a distribution of pockets holding quanta of liquid medium may also be used. Diffusion may be increased by superimposing an electric field. A glass sheet may be chemically toughened differentially by using a perforated or apertured wall in contact with the article surface. Powdered carbon and silica can be added to the treatment bath to raise its viscosity, as well as glasses, e.g. borosilicate glasses, preferably potassium glasses, zeolites, montmorillonites, bentonites, kaolins, micas such as muscovite, biotite, leucite, kaliophylite and microline, silica gels, glauconite and phlogopite. The substance added to increase the viscosity can also serve as an ion-exchange material which absorbs ions coming from the article and releases further quantities of ions which are to be introduced into such material, e.g. montmorillonites and bentonites enriched with potassium or other ions.

Patent ES-430764-A1 (ES)
Title: Method for pressure casting
IPC: B22D17/32
Filed: 1974-10-07
Abstract: In the method, a shot sleeve, for receiving a metered quantity of melt through an inlet or filling opening and connected to the mold cavity, has its volume continuously diminished in such a manner as to maintain a constant communication between the space above the melt in the shot sleeve and the mold cavity for escape of all the gas or air above the melt into the mold cavity before the opening of the shot sleeve into the mold cavity is completely closed by the advancing melt. This is effected, during the shot-pre-filling phase, by an accelerated motion of an injection piston from a rest position, at which the filling inlet to the shot sleeve is open, through the shot sleeve toward the mold cavity opening. As a result of the accelerated motion of the piston, the melt spreads over the melt engaging surface of the injection piston and the formation of a standing wave is prevented. During the mold-filling phase immediately following the pre-filling phase, as soon as the melt surface has reached the casting gate leading to the mold, the metered quantity of melt is displaced through the casting gate into the mold cavity. The mold-fillling phase, which follows the pre-filling phase, may be effected in various sequences of motion of the injection piston. The device for performing the method includes a shot valve controlling the delivery of hydraulic pressure to the injection piston in a preselected manner to provide desired acceleration of the piston in the shot sleeve, and electromagnetically actuated valves, check valves, and chokes are associated with the shot valve to effect a coordinated operation thereof in controlling the movement of the injection piston.
Patent ES-431089-A1 (ES)
Title: Method for gaseous reduction of metal ores
IPC: C21B13/00
Filed: 1974-10-16
Abstract: An improvement in a method for the batchwise gaseous reduction of metal oxides, e.g., iron ore to metals, e.g., sponge iron, in a multiple unit reactor system of the type in which separate bodies of metal-bearing material are simultaneously treated in one or more charging reactors, reduction reactors and cooling reactors and a reducing gas is passed successively through the cooling and reduction reactors. The reducing gas is recirculated in both the cooling reactor and the reducing reactor to increase the mass flow rate of the gas. By recycling the gas to the reduction reactor acceptable reduction can be achieved in a shorter period of time and with a single reactor. Also the temperature gradient through the bed is reduced thus producing a higher average temperature in the bed for a given inlet temperature and more nearly uniform metallization is obtained.

Abstract: A yarn is liq. treated by being fed by feed rolls into a chamber contg. a treatment liq. and in a helical path a around guide rollers, before being fed out of the chamber through delivery rolls. Pref. between the guide rollers the yarn passes between. Squeezer rolls and the bottom portion of each loop of yarn passes through the liq. in a corrugated formation. A feeler contacts a loop of yarn and dependent on the tension controls lifting devices to move the yarn and increase the size of the loop, so as to reduce the feed rate of the yarn.
