Title: Improvements in or relating to the treatment of cellulosic material
IPC: D06M14/22
Filed: 1961-04-25
Abstract: Cellulosic material, particularly cellulosic textile material, is treated with a sensitizer comprising an ethylenically unsaturated compound, an aromatic compound or a primary, secondary or tertiary amine, and then subjected to ionizing radiation to effect cross-linking of the material. The sensitizer is used in a small proportion, defined as sufficient to effect the desired cross-linking without changing the appearance or finish of the material. Preferred sensitizers are (a) aromatic hydrocarbons having at least two uncondensed benzene rings, e.g. 1,4-diphenyl benzene, diphenylmethane, triphenylmethane, fluorene, benzal- and benzyl-fluorenes and hexaphenylethane (b) unsaturated aliphatic aldehydes, e.g. crotonaldehyde and citral (c) unsaturated aliphatic ketones, e.g. phorone and 2-methyl heptenone (d) aromatic saturated and unsaturated ketones, e.g. benzophenone, chlorobenzophenone, benzalacetophenone, dicinnamylidene acetone, benzoquinone, diphenoquinone and a -naphthoquinone (e) aromatic hydroxy ketones, e.g. p-hydroxyacetophenone and (f) primary, secondary and tertiary aliphatic amines having 4 to 20 carbon atoms and aromatic amines having 1 to 3 benzene rings with 1 to 3 amine groups attached to the ring(s), e.g. aniline, diphenylamine, tributylamine and cyclohexylamine. Suitable radiation includes g -, b - and X-rays at a preferred total dosage of from 5X104 to 3X106 rads. The process may be applied to cellulosic yarns, filaments or threads, or to woven, knitted and unwoven fabrics of natural or regenerated cellulose, or to such materials containing cellulosic fibres, and which have been provided with a resin finish. The material may be impregnated with a solution or dispersion containing less than 15%, e.g. 0,1 to 5%, by weight of the sensitizer. Treatment with a sensitizing compound prior to irradiation obviates the need for the heating step disclosed in Specification 895,479, or irradiation in substantial absence of oxygen as in Specification 916,567. The treated materials have improved tensile strength, and increased abrasion, crease and tear resistance.

Title: Control circuit for electrodeposition system using silicon controlling rectifiers
IPC: C25D21/12
Filed: 1967-06-17
Abstract: An electro-deposition apparatus is provided with means whereby the plating current is controlled initially at one constant value and subsequently at a second constant value and the increase in current from the first value to the second value having a constant rate. The current supply to a pair of plating electrodes is controlled by varying the voltage output of a silicon controlled rectifier device 22, the control being effected by way of a differential amplifier 23 comprising saturable reactors, whereby the phase of the gate signals for the thyristors is altered in accordance with the error signal between the thyristor output voltage and the desired output voltage represented by an input signal E. The signal E is varied to produce the desired plating current pattern, a relay contact 14 first being set, manually or otherwise, in the position 15 16 when the initial constant value of the plating current is adjusted by variable resistor 13. After a given time period the contact 14 is moved to position 16, 18 when a D.C. amplifier 10 together with a capacitor 11 becomes an integrating amplifier whereupon the plating current is caused to increase linearly, at a rate set by variable resistor 20, until it reaches the second constant value adjusted by a potentiometer 21, the diode 17 forming a clamp to prevent any increase in the signal E when it reaches a value set by the potentiometer.

Patent ES-360425-A1 (ES)
Title: Device for testing the vigilance of a person
IPC: A61B5/18
Filed: 1968-11-19
Abstract: A device for testing a person's vigilance comprises a plurality of simultaneously and independently operable luminous indicators, at least two energy sources adapted to individually operate separate ones of the indicators at different luminosities or frequencies of variation of luminosity, thereby allowing comparison of two or more indicators whereof the luminosity of at least one indicator varies at a frequency within the person's flicker fusion threshold range, which frequency may be continuously adjustable within said range for said one indicator. A vehicle driver testing device comprises a row of seven luminous indicators 1 to 7, and associated interlocked test switches 1c to 7c which are interconnected with a commutator unit so that, when a test switch 10 is closed, one indicator is chosen in a random manner to flicker and the others are connected to a d.c. supply. If the driver has sufficient vigilance he will pick out the flickering indicator and may press the handle operable switch from the set 1b to 7b, associated one with each indicator, associated with the flickering indicator to complete the ignition circuit of the vehicle to enable it to be started. At the end of a relatively short time switch 10 is automatically opened to break the ignition circuit unless the appropriate switch 1b to 7b has been previously operated to complete the circuit and supply current to a holding coil 12 of a shorting switch 11 for switch 10. A second vehicle driver testing device, Fig. 2 (not shown) comprises a luminous indicator (22) driven by a generator (26), preset to a certain frequency, and a second luminous indicator (23) alongside the first driven by a generator (28) having a scale (25) attached to a potentiometer for adjusting its frequency. To start the vehicle an ignition switch (42) is first closed and if the driver has the required level of vigilance he may adjust the frequency of flickering of the second indicator (23) to match that of first indicator (22). The frequencies are compared by a comparator (29) which when they are equal actuates interlocking circuitry which enables the car to be started if the driver has a level of vigilance such that he is able to join a movable contact (40) to a fixed (39), and hence complete a circuit, by passing the movable contact (40) vertically between two contact bars (41) without touching either of them with contact (40). The interlocking circuitry also prevents starting of the car if the frequencies of the indicators are not first matched before the contacts (39) and (40) are joined in the manner described above.

Title: Tank washing apparatus
IPC: B08B9/093
Filed: 1968-11-25
Abstract: Apparatus for washing tanks includes a nozzle mechanism for spraying the interior of a tank and a control unit which is attached to and controls the nozzle mechanism in order to concentrate the spray on the dirtier areas of the tank, i.e. on sediment in the lower parts of the tanks. A nozzle 18 is mounted on sleeve 22 which is rotatable (through 360 degrees) about a pipe 19 connected to a supply of washing liquid, the nozzle 18 being rotatable (through 180 degrees) about an axis perpendicular to the axis of rotation of the sleeve 22. Control Unit. The unit, Fig. 5, is mounted on the nozzle mechanism outside the tank and a rotatable control shaft 24 extends from the unit through the pipe 19 and sleeve 22, the shaft 24 being attached to the sleeve 2 and being connected via a rod 32 to a rack 30 which moves up and down in accordance with up and down movement of the shaft 24 to rotate nozzle 18 via a pinion 28 and a hub 26. Rotational and up and down movement of the shaft 24 is transmitted from a screw 100 disposed within the unit, the screw passing through a nut 116 which may be held stationary or may be rotated. The screw 100 is rotated from a reversible motor 60 via a worm 84 and a gear 112, the screw then moving up and down through the stationary nut 116 so that both the sleeve 22 and the nozzle 18 rotate about their respective axes, this operating giving a coarse washing action. For fine washing action, the shaft 82 of worm 84 may be geared, via a clutch, to the shaft 94 of a worm 96 which rotates nut 116 in the same direction as screw 100 via gear 128. The gear ratio between the two shafts 82, 94 is such that the nut 116 rotates slower than screw 100. The gear ratio may be varied, and provision is made to rotate nut 116 manually. The screw 100 is provided at its upper end with a cam 140 which actuates three valves 144, 146, 142, any one of which may reverse motor 60 to rotate the screw 100 and nut 116 in the opposite direction. On reversal of the direction of rotation of the screw 100 there is a delay, e.g. of 90 degrees, provided by a lost-motion device, until the direction of rotation of nut 116 is reversed, thus giving a fine spray path from nozzle 18. Operation. Cam 140 moves from valve 142 until it actuates valve 144 to reverse motor 60 to move screw 100 downwardly, the cam 140 then passing valve 144 until it actuates valve 142 to again reverse motor 60 to move screw 100 upwardly until cam 140 actuates valve 146 to again reverse motor 60. Cam 140 then travels between valves 146 and 142 until washing is complete. Valve 146 may be adjusted vertically so that initial movement of cam 140 between valves 142 and 144 rotates nozzle 18 through 180 degrees and subsequent movement of cam 140 between valves 142 and valve 146 rotates nozzle through an angle of less than 180 degrees depending upon the position of valve 146. Washing is then concentrated on the dirtier lower part of the tank. A control circuit, Fig. 16 (not shown), incorporating valves 144, 146, 142 and motor 60 is illustrated. A number of these apparatuses may be provided in one tank.
