Title: Flavor improvement process for coffee
IPC: A23F5/04
Filed: 1967-03-03
Abstract: In treating whole, subdivided or ground roasted coffee beans, hereinafter referred to as "beans" and "roasted coffee beans", to remove aromas and unwanted gases and thus improve the beans, roasted coffee beans, throughout which 4 to 40% by weight of moisture is equilibrated, are tempered under temperature and pressure conditions and for a time sufficient to allow the moisture. to make contact with the aromas and unwanted gases present, but insufficient to effect further roasting, and' then at least some of the moisture is evaporated. Said range in moisture content may be attained by adding 5 to 35% by weight of water, e.g. water which has been used to quench roasted coffee beans, to freshly roasted coffee beans. Equilibration of moisture content and tempering may be effected at ambient temperature, or by heating roasted coffee beans under super-atmospheric pressure, e.g. in a closed pressure vessel in the presence of water or live, pressurized steam and then opening the vessel to reduce the pressure to atmospheric pressure (see Examples III and IV). Aromas may be recovered from the evaporated moisture, and concentrated, and blended with soluble coffee solids obtained from the treated roasted coffee beans, as by percolating hot water through them to yield an aqueous extract, and then spray-drying this extract.

Patent ES-341586-A1 (ES)
Title: Color television display device
IPC: H04N9/28
Filed: 1967-06-09
Abstract: In a convergence correction circuit for a three-beam colour television display cathoderay tube the negative half of the field sawtooth deflection waveform, the sawtooth portion of which is symmetrical about zero potential controls convergence correction in one half of the display and a positively going pulse developed during fly-back controls the correction in the other half of the display. Thus during the negative half of the field sawtooth waveform which is supplied at terminals 20 1a 201b (Fig. 2) current flows through the R (red) G (green) and B (blue) convergence correction coils via diodes 204, 205, 216 and 217 this current being integrated by the coils to vary parabolically and so produce the required convergence in one half (the lower half) of the display. During the occurrence of the subsequent fly-back portion of the sawtooth wave the reversal of polarity of the latter cuts-off diodes 204, 205, 216, 217, the current in the convergence coils commences to decrease exponentially and the polarity across the coils reverses. Diodes 207, 231 and 239 now conduct and a positive bias voltage developed across the RC circuit 209, 211 and which exceeds the maximum value of the positive part of the sawtooth and ensures that diode 207 conducts only during the pulse portion of the fly-back is applied to both ends of coils R and G via diode 231 and resistor 233 and to one end of coil 13 via resistor 238 and diode 239. This voltage modifies the decreasing current in the coils and by adjustment of resistors 233 and 238 the convergence correction in the upper half of the display may be controlled independently of the correction in the lower half which is effected by resistors 203 and 220. For static convergence at the centre of the display, potentials developed across potentiometers 234, 236 and 251 by rectification of line fly-back pulses are utilized. In a modification, the negative part of the field sawtooth wave is fed to the convergence correction coils via a saturable inductor shunted by a resistor which operates by virtue of its inductance-current characteristic to improve the shape of the resulting parabolic current in the coils (Figs. 3 and 4, not shown).
Patent ES-344800-A1 (ES)
Title: Hydromechanical gauge control system for a rolling mill and like device
IPC: B21B31/32
Filed: 1967-09-06
Abstract: A rolling mill incorporates a roll-gap adjusting rod 16 which bears on an upper roll chock 13 and is formed at its upper end with an integral piston 22, movement of the rod being restricted by an axially adjustable sleeve 26. A spring 34 is located between the piston and sleeve and permits limited movement of the rod, subject to the spring compressibility. The sleeve is moved axially by a worm and pinion mechanism 29 to adjust the roll-gap, and is subject only to the difference between the hydraulic load on the piston and the rolling load. The spring allows, for example, 0À080 inch adjustment of the rollÀgap and can withstand a load of 200,000 lbs. A control circuit for providing automatic gap control, maintains the pressure applied to the piston at a value of P(Y+1) where P is the rolling load and Y is the ratio of the moduli of the spring 34, and of the mill, including the housing 11. Values of the rolling load from a load cell 17, of the mill modulus, spring modulus, and roll and strip width characteristics are fed to the circuit by potentiometers, the output of the circuit controlling the pressure value P(Y+1). The shape of the rod 16, and the disposition of the spring 34 can be changed, Figs. 3-5 (not shown). The rod 16 may be positioned at the base of the housing 11, and may be associated with two-high or four-high mills.

Patent ES-420909-A1 (ES)
Title: Method to improve adhesive of polyolefin surfaces
IPC: C08J7/043
Filed: 1973-11-27
Abstract: A powder of a polyolefin, such as a normal polyethylene, having a melt index of between 2 and 20 is oxidized slightly and thereafter is sintered into a layer which will adhere strongly by thermal fusion to a polyolefin surface and also to a polar surface such as that of a layer or article composed of a polyamide, polyurethane or polyester resin. Large industrial articles such as containers and building construction elements can be produced with desired strength and surface properties by use of a sintered layer of that oxidized polyolefin powder to join to a polyolefin layer a layer of a polar resin or a different polyolefin layer. By being sintered in the presence of a blowing agent, the slightly oxidized powder forms a foamed bonding layer which will securely join together layers having different thermal expansion coefficients.
