Inventor: ZINEBI ABDELALI
IPC: A61C17/22
Filed: 2018-04-27
Abstract: Il s'agit d'une brosse à dent, je dirai, électronique à tête cylindrique, actionnée par un moteur à courant continue, son mode de fonctionnement repose sur la méthode de brossage dentaire dite « du rouleau» ; c'est-à-dire que la brosse doit toujours effectuer un mouvement rotatif continu de la gencive vers les dents. Elle comprend un manche où sont rassemblés les principaux composants qu'on va décrire, et une tête cylindrique avec une partie travaillante (demi-cylindre) qui sera directement en vis-à-vis des dents pour en assurer le brossage, l'autre moitié du cylindre sera protégée par un écarteur en forme de demi-cylindre, destiné à protéger les muqueuses pendant le brossage son principe de fonctionnement met en oeuvre un système de gyroscope accéléromètre, capteur de température, (exemple un gy-521) qui mesure les angles formés par l'axe de la brosse par rapport au plan horizontal et transmet les valeurs à un microcontrôleur, véritable cerveau où sont stockées toutes les commandes, à son tour relié à un pont en h qui permet d'inverser le sens du courant délivré à un moteur à courant continu, qui lui est relié, suivant les angles. Elle comprend un bouton poussoir marche/arrêt que je nommerai bouton poussoir d'alimentation pour la 'mise sous tension, deux boutons (+) et (-) pour augmenter ou diminuer la vitesse de rotation de la brosse suivant la demande. Ces boutons sont reliés au microcontrôleur à qui ils transmettent des impulsions, et, par un programme informatique basé sur le principe de la pwm (pulse width modulation), permet d'accélérer ou de ralentir le moteur. Elle comprend aussi un bouton poussoir qui permet de basculer entre les modes haut et bas suivant l'arcade dentaire à brosser. Tout ceci est géré par un programme informatique supporté par le microcontrôleur (exemple un atmega 328p), le capteur de température permet éventuellement de couper le courant en cas de surchauffe, pour ce faire, on mettra ce composant le plus près possible du moteur pour que la mesure soit la plus fiable possible.

Patent ES-292550-A1 (ES)
Title: Process and apparatus for the manufacture of flat glass on a molten metal bath
IPC: C03B18/04
Filed: 1963-10-16
Abstract: In a process for manufacturing flat glass on a bath of molten metal, a layer of molten glass is caused to flow from a melting furnace at a substantially constant level over an overflow and to slide down an inclined plane on to the surface of the molten metal, the inclined plane extending into the molten metal such that the layer of glass remains supported throughout its entire travel. Glass 4 (Fig. 1, not shown) from a melting furnace is caused to flow under a baffle 2 and over a weir 6 at a constant level to form a layer of glass 23 which slides down an inclined plane 11 on to the surface of a bath of molten metal 7. A vertically movable baffle 18 defines the downstream end of the feeding chamber. To prevent bowing of the inclined plane 11, the plane is provided with two longitudinal extensions 12 supported relatively to one another by transverse bars 13, and between these extensions two opposite handed screws are provided to vary the tension on the surface of the plane. In order to prevent the occurrence of temperature gradients throughout the depth of the glass layer burners 22 are provided in the feeding chamber. A burner 24, or electrical heating elements housed in the inclined plane, are also provided to maintain the lathe at the temperature of the glass. The inclined plane, which may be adjustable to allow for varying glass thicknesses, is made from a heat resistant metal with a platinum covering.
Patent ES-293070-A1 (ES)
Title: Flame detector
IPC: F23N5/08
Filed: 1963-10-31
Abstract: In a flame detector, random pulses produced by avalanche processes in a glow discharge detector tubes due to radiation from the flame, are transmitted to a receiver circuit which includes e.g. a relay which actuates an indicator to show whether or not the flame is alight. The lightly loaded transmitter circuit includes the discharge tubes UV (Fig. 8) arranged to produce pulses superimposed randomly as voltage spikes on the A.C. supply waveform from 10. The duration of the pulses is increased by means of R 1 and C 1 . The pulses are separated from the supply by means of capacitors C 2 and C 4 and the negative pulses shorted to earth through diode D 2 . The positive pulses trigger on an S.C.R. the signals from which are stored in a tank circuit K L , C 5 . The diode D 1 produces halfwave rectification for the receiver supply. On extinction of the flame, the pulses from the U.V. tubes stop and the relay is caused to actuate an alarm or indicator. A circuit to check whether or not the S.C.R. and other components are operating correctly, involves a bridge rectifier 26, tuned to a band of frequencies about the random signal frequency, having a relay 28 which can operate an alarm 34 if a fault is detected, and which can be connected either across the relay R L or across the secondary of a transformer (Fig. 9, not shown), the primary of which is connected in the output of the receiver. Various modifications of the receiver circuit are described. In one (Fig. 4, not shown), negative pulses from the transmitter switch on the transistor Q 1 and capacitor C 6 is charged to a desired value, and increases the time constant of the gate pulse to the S.C.R. The rate of firing of the S.C.R. is again dependent on the rate of pulses from the tubes UV. The capacitor C 7 helps the S.C.R. to recover after each pulse. The circuit has a full-wave rectified supply at a low voltage, an alternative highvoltage circuit being provided in a circuit which includes a Zener diode and a resistor to limit the voltage across the transistor (Fig. 5, not shown). In a high-voltage circuit which may be supplied by a half-wave supply (Fig. 6, not shown), the capacitor C 6 may be omitted since a shorter gating time is required for a higher voltage S.C.R. A transistor Q 2 (Fig. 7, not shown) may be used to receive the pulses from the transmitter and forms part of an emitter follower circuit. The emitter-collector current is limited by resistor R 6 . C 8 acts to store some of the energy of Q 1 to maintain Q 3 turned on between signal pulses to Q 2 . Transistor amplifier stages are provided with relay R L as the load for transistor Q 4 .

Title: Purification of olefinically unsaturated nitriles by water extractive distillation
IPC: C07C67/00
Filed: 1966-12-09
Abstract: A crude olefinically-unsaturated nitrile, such as acrylonitrile or methacrylonitrile obtained by a catalysed reaction between ammonia and propylene or isobutylene respectively, is purified by introducing the crude nitrile through line 10 into column 11 where it is submitted to extractive distillation using water as solvent the vapours leaving the top of the column through line 13 are condensed forming a condensate which separates into a water layer and a purified nitrile layer. Impurities, such as acetonitrile, propionitrile and hydrogen cyanide, leave the base of column 11 in the form of an aqueous solution, which is heated in stripping column 15 to distil off the impurities. The purified water withdrawn from the base of column 15 is returned through lines 21 and 12 to the upper section of column 11. Vapours are withdrawn from an upper section of column 15, and are introduced through line 22 into the lower section of column 11, thereby supplying the heat for the extractive distillation. Impurities are discharged from the system through line 20 which leads from condenser 18. An alternative apparatus is described wherein part of the stripping zone is directly connected to the lower end of the extractive distillation column. Reference is made to the purification of crude aqueous acrylonitrile obtained by reaction of ammonia and propylene, and treatment of the synthesis vapour product with water which dissolves acrylonitrile but not the unreacted hydrocarbons, carbon monoxide and carbon dioxide.
Patent ES-334912-A1 (ES)
Title: Electrical discharge machining power supply circuit
IPC: B23H1/02
Filed: 1966-12-24
Abstract: An electro-erosion apparatus comprises a power source 132, Fig. 1, connected across the gap between an electrode 130 and workpiece 128 through an electronic switch 110 whose control electrode is triggered by a first pulser 10, 12 providing variable on and off time pulses, a sensing means 150, 152, Fig. 2, providing a signal output responsive to abnormal conditions, such as a short-circuit, across the gap, cut-off means 160 connected to the sensing means to interrupt operation of the switch 110 when abnormal conditions occur, a second pulser 190, 192, 194, 196, supplying cut-off pulses to the cut-off means 160, and means 202 for varying the duration of the cut-off pulses. The first pulser is an astable multivibrator formed by tubes 10, 12. The pulse frequency is varied by switched condensers 34, 36 and the on-off ratio may be adjusted by rheostat 46 between eighty and one per cent. The output from the multivibrator is passed through amplifiers 56, 68, 76, which may comprise banks of tubes to a transformer 92, whose secondary winding controls the bases of a bank of power transistors 110 forming the electronic switch. The latter may alternatively comprise vacuum tubes, ignitrons, thyratrons, or semi-conductor controlled rectifiers. If an abnormal condition, such as a short-circuit, occurs in the gap, the sensing means 150, 152, Fig. 2, responsive to peak gap voltage, transmits a signal through diodes 182, 184 to base of transistor 160 to render it conductive. The collector of this transistor is connected to the control grid of multivibrator tube 10 whereby a negative voltage occurs on this grid and stops the multivibrator. During this stop period, however, low frequency pulses of 50-60 c.p.s. are applied to the switch 110 under the control of the second pulser comprising a relaxation oscillator formed by a four-layer diode 190 and network 192, 194, 196 supplied from transformer 186. These low frequency pulses are applied through diode 212 to base of transistor 160 to render it non- conductive, thus periodically reactivating the multivibrator which automatically begins normal operation when normal conditions are restored in the gap. The low frequency pulses are varied in their on-off period by a potentiometer 202 which is preferably operated in unison with the rheostat 46. A dielectric such as kerosene, transformer oil or distilled water is circulated through the gap and the latter is controlled by a servo feed unit for the electrode 130.

Title: Container and method of forming the same
IPC: B65D43/02
Filed: 1967-02-08
Abstract: A seam release strip 20 of a plastics material is secured to a tubular container body 12, which may be of compressible material, by means of a layer 22 of adhesive. After the strip 20 is applied, an end closure 18 is fitted, Fig. 4 (not shown), and its curled rim 34 is bent downwards to form a seam 40. Pressure by the rim 34 causes the end of the body 12 to be indented, as shown, and the strip 20 to be reduced in thickness. The body 12 is inverted for filling and application of a bottom closure 14. In use, a tab 24 on the strip 20 is pulled to release the strip, the thicker upper portion 44 of the strip being caused to elongate so that it passes between the rim 34 and body 12. The closure 18 may be re-used, its countersink wall forming a friction fit with the inner face of the body 12. Materials.-The body 12 may be of fibreboard, formed convolutely, helically or with a lap seam alternatively, it may be of plastics, glass or metal. Liner and label plies (not shown) may be of metal foil or plastics film. The end closures 14, 18 are of metal. The adhesive layer 22 may be a pressure sensitive or thermoplastic adhesive. The strip 20 may be of polyethylene or polypropylene, and may be laminated. Modification.-The pull tab may overlap with the opposite end of the strip 20, Fig. 3 (not shown), its upper edge being cut away to avoid a double thickness in the seam.
