Title: Method of treating anemone bulbs
IPC: A01G7/00
Filed: 1961-10-11
Abstract: A method of treating anemone bulbs to prevent or modify their germination, comprises saturating the bulbs in water, e.g. for thirty-six to forty-eight hours at room temperature, surface-drying the bulbs, e.g. at 4 DEG to 6 DEG C., preferably 4.5 DEG to 5.5 DEG C. for seven to ten days, and then enclosing the bulbs in air-tight packages such as plastic bags. If the packed bulbs are to develop no apparent germs, they are submitted to a temperature of 1 DEG or 2 DEG C., or lower, for fifteen days or more. If fully apparent germs are required, the drying temperature, after the seven to ten day period, is raised, over four or five days, to 13 DEG C., and this temperature is maintained for ten more days.

Title: Improvements in switching circuits
IPC: H02P1/44
Filed: 1964-03-25
Abstract: A capacitor 20 in the phase winding 16 of a single-phase induction motor is connected to the supply 14 through two rectifiers 22, 24 connected in opposition, one of which is a thyristor. As shown, triggering voltage is produced across an impedance 26 by the main winding current when this drops with the attainment of running speed the voltage is insufficient to trigger and so the capacitor 20, being energized through rectifier 22 only, is rendered inoperative. The impedance 26 may be replaced by an impulse transformer. The phase winding may continue to be energized after starting through a " run " capacitor 18.
Patent ES-307420-A1 (ES)
Title: Improvements in and relating to switching networks for use in telecommunication exchanges
IPC: H04Q3/52
Filed: 1964-12-22
Abstract: In a multistage switching network utilizing transistors as the cross-point switches in the speech wires, the transistors are initially operated and then held by means of bi-stable elements located in the c-wires. PNP, NPN or photo transistors (Fig. 2, not shown) may be used and the bi-stable elements may be PNPN transistors or the combination of a phototransistor and light source (Fig. 3, not shown). In the latter case the light source, which is in series with the photo transistor in the c-wire, is also used for operating the photo-transistors of the speech cross-points. Operation.-A marker closes switch S in the c-wire of the selected path and reduces the potential on terminals 1 to 4 (of stages I to IV) from - 80 to - 60 v. PNPN transistors trc 1 to trc 4 in that order trigger-on successively and then hold even when the input potential restores to - 80 v. The conduction of the c-wire transistors causes the speech wire NPN transistors tra and trb to energize. The latter are held from the c-wire until the connection is released by opening S.

Patent ES-345470-A1 (ES)
Title: Process for the Production of Formaldehyde.
IPC: C07C45/38
Filed: 1967-09-26
Abstract: Formaldehyde is produced by the oxidation of methanol with a surplus of air in the presence of a metal oxide catalyst, the air being preheated in a co-current heat-exchanger by the hot gases from the reaction. The methanol may be first evaporated and preheated, e.g. by steam in a counter-current heat exchanger, and then mixed with the heated air, or evaporated by the heated air in an evaporator, with subsequent re-heating of the gas mixture if necessary, or may be injected straight into the hot air stream. The temperature in the reactor is regulated in the usual way with a heat transfer medium, itself cooled in a heatexchanger and the surplus heat used to generate steam. After cooling in the co-current heat exchanger, the reaction gases are passed to an absorption system for absorption of the formaldehyde, e.g. in water.

Title: Template-controlled tool grinding machines
IPC: B24B3/40
Filed: 1968-01-16
Abstract: A copying machine for grinding a turning tool 23 comprises a grinding wheel 3, an adjustable arm 8 rigidly connecting a ball joint 10 and a bearing plane 11 which lie in a common plane, a swivel arm 16 mounted on the ball joint, a template 19 having the nose angle 22 of the tool to be ground and mounted on the swivel arm for engagement with the bearing plane, means for clamping the tool to be ground to the swivel arm, a slideway 7 to allow pivotal movement of the adjusting arm 8 about an axis 26 extending parallel to the grinding plane and perpendicular to the line of alignment 12 between the centres of the bearing plane and ball joint, and a slideway 1 for adjusting the spacing between the grinding plane and the centre of the line of alignment. In Fig. 2 (not shown), the machine is set for grinding a tool without a nose radius, the pointed tip of the tool being in line with the centre of the line of alignment 12 as indicated by the tip of an indicator (36) which is retracted before grinding is commenced. The tool is pushed beyond the tip of the indicator a distance corresponding to the amount to be ground off and then clamped. For adjusting the clearance angle, the adjusting arm 8 is displaced on the slideway 7 which is calibrated at 45. Grinding is effected by manually swivelling the arm 16 and pressing the tool against the grinding wheel until the template 19 bears against the bearing plane 11. In Fig. 3 (not shown), the machine is set for grinding a tool with a nose radius, the tip of the tool being set beyond the line of alignment 12 by an amount equal to the desired radius plus the amount to be ground off the nose radius is set by displacing the assembly relative to the grinding wheel on the slideway 1 which is calibrated at 43.

IPC: B01J23/70
Filed: 1968-04-24
Abstract: In a method of making methane from hydrocarbon feedstock containing 2 or more carbon atoms by hydrocracking the feedstock in a bed of highly activated solid nickel catalyst, steam in an amount sufficient to control the maximum temperature of the bed in the range 400 to 600 C. is passed through the bed which is indirectly cooled so that the exit temperature of the bed is at a value at least 100 C. lower than the maximum temperature. The hydrogen which should comprise 90 to 150% of the amount theoretically required to produce methane from the feedstock, may be any H 2 - containing gas, and feedstocks mentioned include naphtha, kerosene, gas oil and 1.p.g.

Patent ES-356873-A1 (ES)
Title: A Device for Measuring Optical Density
IPC: G01J1/24
Filed: 1968-08-03
Abstract: In a null balance two path absorptiometer an optical wedge in the reference path is shifted by a pulse motor energized by an oscillator with a frequency proportional to the amplitude of the out of balance signal. Light from a monochromator 3 is switched alternately through a sample 6 and an optical wedge 7 to fall on a photocell 8 connected to a phase sensitive rectifier 9. The oscillator 11 has two channels each comprising transistor-capacitor relaxation oscillators having a frequency controlled by the magnitude of the output of rectifier 9 (one channel if the output is positive, the other if negative). The pulses are fed to a step-by-step wedge motor 13 and an up/down counter 14. The count may be used retro-actively in a chemical process control or to give an alarm at a pre-set value. Automatic titration The absorptiometer may be associated with an automatic titrimeter in which an oscillator energizes a step-by-step motor of a mechanical burette so as to record volume against absorption on a two channel recorder. Alternatively the burette motor may be stopped when a pre-set count on counter 14 shows that the end point has been reached. If the end point corresponds to a point of inflexion on the absorption curve, it may be detected by applying the pulses to a ratemeter and differentiator.
