Title: Improvements in or relating to high current circuits
IPC: H01S3/00
Filed: 1967-04-17
Abstract: 1,123,654. Pulse generating circuits. COMPAGNIE GENERALE D'ELECTRICITE. 17 April, 1967 [29 April, 1966], No. 17494/67. Heading H3P. [Also in Division H1] In a circuit for discharging a capacitor 8 through an inductor 9, the inductor is connected across the capacitor via a first spark gap A, triggered by a laser 1, a second spark gap B having a dielectric screen 7 being shunted across the inductor 9 after a delay equal to the time necessary for the laser beam to destroy the dielectric screen 7. The field of the inductor 9 may be used to concentrate a very high temperature plasma in a discharge tube 34 ionized by discharge of a further capacitor 31 via a further laser-triggered spark gap D. After a further delay equal to the time taken for the beam from the laser 1 to destroy a further dielectric screen 24, spark gap C breaks down, discharging capacitor 21 via the winding 11 of a relay 10 which short circuits inductor 9 so as to prolong the discharge current therein. The beam on the laser 1 is distributed by a half-silvered mirror 3. The dielectric screen 7 may be copper coated so that the resistance of spark gap B is only a few milliohms, a lens 12 being provided in a bore in electrode 5 so as to focus the laser beam on to the screen 7. Fig. 3 (not shown) relates to the output current and voltage waveforms which are arranged to be aperiodic by allowing spark gap B to break down when the otherwise oscillatory voltage passes through zero.

Title: Process for the production of esters of sugars, hexitols and anhydro-sugars
Inventor: CARDY CHARLES FREDERICK
IPC: C07H13/06
Filed: 1958-06-02
Abstract: A fatty acid ester or partial ester, or a mixed ester, of a sugar, hexitol or anhydrosugar is made by subjecting a fatty acid ester in which the acid radical contains from 12 to 30 carbon atoms and the alcohol residue contains from 1 to 3 carbon atoms, or a mixture of such esters, to alcoholysis with the sugar, hexitol or anhydro-sugar, in the presence of an alcoholysis catalyst in a liquid reaction medium inert under the reaction conditions and of such a kind and present in such quantity that the catalyst, and the sugar, hexitol or anhydro-sugar, are soluble, but the fatty acid ester or mixture of fatty acid esters is substantially insoluble, and intimately contacting the phases of the reaction mixture, in a thin film, under conditions such that there is rapid evaporation of the alcohol liberated in the reaction.  The preferred solvents are dialkyl sulphoxides having not more than 3 carbon atoms in the alkyl groups, e.g. dimethyl sulphoxide.  Sucrose, sorbitol, mannitol, dulcitol and sorbitan are suitable starting materials.  The intimate contacting may be effected by maintaining vigorous turbulence of the solid and liquid phases during the reaction.  The reaction may be effected in a thin-film type evaporator, such as a cyclone evaporator, a rotary film evaporator, or a calandria type of heater in which the reaction mixture is thrown across the surface of the upper part of the flask as a thin film of the mixed phases.  Mixing pumps, turbo dispersers or other mixing devices may also be used in combination with means which provide a thin film of the temporarily mixed phases.  Examples describe the reaction of sucrose with methyl stearate or palmitate in dimethyl sulphoxide in the presence of potassium carbonate, the reaction being carried out in a cycle evaporator fitted with a column and take-off head.

Title: Means for fluting milling rolls and the like
IPC: B23G1/02
Filed: 1922-06-28
Abstract: 199,262. Praeg, L. June 28, 1922. Shaping helical surfaces.-In a roll fluting machine of the type in which the roll or other like article is arranged vertically and relative axial reciprocation is provided between the work and an angular surrounding tool-saddle containing simultaneously operating tools, the saddle is non-rotatable and the work is rotated by mechanism mounted on the workholder. A base 1 supports three columns 3 on which slides an annular saddle 16 carrying radially adjustable tools 18 provided with the usual clapper arrangements (nob shown), and reciprocated by screws such as 19<a> inside the columns. The screw 19 is rotated from a balt pulley 25 by bevel' gearing 22, mounted on a fixed head 2, while the other screws receive their motion through bevel pinions 27 from the wheel 22. Reversal is effected by a dog 36 on the saddle striking tappets 34, 34a through the medium of springs 35, the idle stroke being at an increased speed. The spindle 4 of the roll 5 to be fluted is centred by steady rests 6, 11, and is supported by a collar 10, a gap 8 in the lower rest facilitating insertion of the spindle, while a gap 9 is provided in the base to accommodate long spindles. The roll is given an oscillating movement about its axis for cutting helical flutes by means of a driver 12 engaging a recess in a chuck 14, rotatably mounted in a sleeve 15. The chuck and sleeve are moved together during the cutting stroke by means of a worm quadrant 42 on the sleeve and a worm driven through reduction gearing from one of the vertical screws, while during the idle stroke the chuck rotates relatively to the sleeve to position the roll for the next flute. This relative rotation is produced by a worm wheel 45 operated by a worm 43 and a ratchet wheel 47 carried by the sleeve, co-operating with a pawl 48 which is adjustably mounted, on a bar 49 pivoted to the sleeve at the end 50 while the other end is slotted and slides on a bolt 52 adjustably secured to a quadrant 53 attached to the head 2. In a modification, the whole machine may be pivoted at the base and counter-balanced so that it may be turned into a horizontal or vertical position to facilitate setting the tools and inserting the work. In a further modification, the saddle is provided with three splayed legs secured to the ground and the base 1 forms a lower connecting head for the columns 3 which are thus reciprocated vertically. In this case the machine is driven by an electric motor connected to and reciprocating with the columns.

Abstract: 149,660. Renault, L. Aug. 14, 1919,. [Convention date]. Void [Published under Sect. 91 of the Act]. Screw propellers. - In screw propellers with adjustable and reversible pitch blades, the adjusting-mechanism is external to the propeller shaft. The adjustment is effected by braking one of two differential pinions, the differential being actuated by the rotation of the propeller. The pitch of the blades is indicated by a pointer driven from the control rod. The roots of the blades 2, Fig. 1, have worm wheels 3, each engaging a worm on a shaft which also has a spurwheel 5. The wheel 5 gears with a gear-wheel 6 on a shaft which is geared by bevel gears to a shaft 10. On this shaft is a worm 11 gearing with a worm-wheel and through pinions with' the internal teeth of a wheel 14 which has external bevel teeth gearing with two bevels 17 having brake drums 18. When the propeller is rotating, all the above gears rotate without relative displacement, the pitch of the blades being constant. By braking one of the drums 17 relative movement takes place and the pitch is adjusted or reversed. The change in the position of the blades is indicated by the lever 23 moving over a graduated arc 24, the other end of which engages a nut 22 on the screwed extension 21 of the shaft 10.
Patent GB-1000888-A (GB)
Title: Coating composition and process
IPC: D21H19/82
Filed: 1964-04-30
Abstract: A paper coating composition having improved wet-rub resistance comprises a mixture of clay and the reaction product of a starch adhesive with a reaction product of a dialdehyde polysaccharide and a dicyandiamideformaldehyde condensation product.  The clay may be hydrated aluminium silicate and the dialdehyde polysaccharide may be periodateoxided starches, gums, dextrans, celluloses or inulins.  The insolubilized, wet-rub resisting composition may be formed by applying an aqueous dispersion of the reaction product of the dialdehyde polysaccharide and dicyandiamideformaldehyde condensation product (see Division C3) to the surface of a paper-borne starch-clay coating, whereupon the said reaction product further reacts with the starch in the starch-clay coating, to give a coated paper having improved wet-rub resistance (see Division B2).ALSO:A composition for insolubilizing clay-starch adhesive paper coating compositions comprises the reaction product of a dialdehyde polysaccharide and a dicyandiamide-formaldehyde condensation product.  An aqueous dispersion of the reaction product may be formed by mixing, at room temperature, an aqueous dispersion of a dialdehyde polysaccharide, e.g. periodateoxidized starches, gums, dextrans, insulins or celluloses, and an aqueous solution of a dicyandiamide-formaldehyd condensation product. The aqueous dispersion preferably has a solid content of 7 to 10% by weight of dialdehyde polysaccharide, and 0.5 to 10% by weight of dicyandiamide-formaldehyde condensation product based on the total volume of the dispersion. The insolubilizing action of the reaction product, a complex resin polymer, is believed to be due to a reaction between aldehyde and methylol groups on the resin and hydroxyl groups on the surface of the starch adhesive coating (see Divisions B2 and C4).ALSO:A coated paper having improved wet-rub resistance comprises a paper substrate provided with a base coating comprising a mixture of clay and a starch adhesive, the base coating having a surface layer comprising a mixture of clay and the reaction product of a starch adhesive with a reaction product of a dialdehyde polysaccharide and a dicyandiamideformaldehyde condensation product.  The coated paper may be prepared by applying to paper an aqueous mixture of clay, e.g. hydrated aluminium silicate, and thin boiling starch, drying at room temperature, and then applying to the surface of the coated paper an aqueous dispersion of the reaction product of a dialdehyde polysaccharide, e.g. periodate oxidized starches, inulins, gums, dextrans or celluloses, and the dicyandiamide-formaldehyde condensation product. The above reaction product water-insolubilizes the surface layer of the claystarch coating by reacting, it is believed, with the starch therein (see Divisions C3 and C4).
