Title: Method for performing welds by the electron beam welding process
IPC: B23K15/00
Filed: 1971-05-03
Abstract: 1325946 Welding by fusion COMMISSARIAT A L'ENERGIE ATOMIQUE 3 May 1971 [29 May 1970] 12781/71 Heading B3R A method of joining three adjacent metal blocks 1, 3, 4 the centre one of which is of different metal from the others, comprises displacing two electron guns 11, 12 simultaneously in parallel motion along the two joint planes. The blocks 3, 4 may be of copper and the centre block 1 of strips 2 of constantan. If only one weld is made at a time by a single gun (Fig. 1, not shown) thermolectric currents generated in the workpieces tend to deflect the electron beam progressively away from the joint plane. An anode 13 connected by a lead 14 to a suitable voltage source may be disposed equidistantly between the guns 11, 12 to prevent mutual repulsion of the beams.

Title: An improved method of manufacturing cellulose films, strips and the like
IPC: C08L1/00
Filed: 1931-05-04
Abstract: Strips, films, &c. of cellulose, more particularly those produced from regenerated cellulose, which are to receive subsequent wet treatments, e.g. photographic films, are subjected to treatment such that the shrinkage capacity from one dry state to the next or from one wet state to the next is reduced to an amount less than 12 per cent.  Distortion of the film by subsequent wet treatment is thereby eliminated.  In one method, the film when produced and finished is held continuously under tension and the marginal portions are removed from the dried films.  According to a modified method the finished strips &c. are alternately wetted and dried at least three times, at least two drying operations taking place under tension and at least one intermediate drying operation being effected without tension.

Title: Pulse-Position Multistable Device for Electronic Systems.
IPC: H03K25/00
Filed: 1967-03-21
Abstract: 1,184,564. Multi stable circuits. ORDENA TRUDOVOGO KRASNOGO ZNAMENI ZAVOD " TOCHELEKTROPRIBOR ". 21 March, 1967 [21. March, 1966], No. 13207/67. Heading H3T. [Also in Division G4] A pulse circuit comprises a storage device which is charged stepwise until its value reaches a desired relation to that across a reference capacitor whereupon the device is discharged and charge leakage from the reference capacitor is replaced. The invention is described in relation to a multi-stable circuit in which the states are represented by the phase of the output pulses. Clock pulses at 14 step up the voltage across capacitor 18 of a diode pump type circuit 17, 18, 21 until the output voltage at 12<SP>1</SP> exceeds a reference value across a capacitor 3<SP>1</SP> whereupon current flows to diode 2 via a transformer winding 22. This renders transistors 24 and 25 conducting, producing an output pulse at 11 and discharging capacitor 18. Thus one output pulse is produced for every " n " input pulse. If the phase of the presently produced output pulses is regarded as a reference then the output train may be moved into any of " n " relative phase positions by adding pulses at 15 to the clock pulse train. Thus, if " n " is 10 a decimal counter is provided. The division ratio or count " n " is determined by the voltage across capacitor 3<SP>1</SP>. A desired value of " n " is set by charging this capacitor from a pulse at 6 to a value greater than the corresponding reference value and applying at 10 a pulse train of the desired output frequency. This will periodically discharge 18 at the desired point and the reference capacitor 3<SP>1</SP> will discharge until it reaches a voltage equal to the maximum step value on capacitor 18. The pulses at 10 may now be terminated. Each time the step voltage across 18 reaches the voltage across 3<SP>1</SP> the discharge will be initiated, the capacitor 3<SP>1</SP> being recharged from point 12 to the level of the highest step by current through diode 2 and this replaces the charge lost by capacitor 3 through resistor 4<SP>1</SP> between output pulses. The range of the circuit may be extended by the use of a non-linear discharge resistor 4<SP>1</SP> or by using a capacitor 3<SP>1</SP> of non-linear type such as a reverse biased diode.

Title: An improved manufacture of refractories
Filed: 1943-08-18
Abstract: A refractory composition for furnace linings comprises a ground magnesian clinker and a small amount of a gel-forming plastic hydrous magnesium silicate, e.g. the material known as "Hectorite," found near Hector, California.  Up to 6 per cent of the normal commercial product, which includes calcite and other impurities, may be added, but 0.3 to 1 per cent is generally sufficient to impart satisfactory plasticity; for addition to refractory mortars, 1 to 2 per cent may be added.  The clinker may contain stabilizers such as boric oxide, chrome ore, or a phosphate to prevent inversion of any dicalcium silicate which may be present, and to prevent hydration, may contain 3 to 4 per cent mill scale, iron oxide or chrome ore, and be dead burnt.  The silicate is dispersed through the ground clinker, and is gelled by the addition of water.  According to examples: (a) a mortar is made from 94 per cent clinker prepared from dolomite, magnesite and chrome ore by burning at 3000 DEG  F. or higher, 3 per cent mill scale, 2 per cent sodium nitrate, all ground to pass a 100-mesh screen, and 1 per cent "Hectorite" ground to pass a 200-mesh screen; (b) a refractory to be used for lining a tap-hole is made by mixing 40 per cent clinker passing 4-mesh, 20 per cent clinker passing 15-mesh, and 31.5 per cent clinker passing 200-mesh, 5 per cent water-soluble sodium silicate, 2 per cent sodium carbonate, 1 per cent trisodium phosphate and 1.5 per cent "Hectorite," the mixture being tempered with about 7.5 per cent water.

The cycle of depositing coloured fibres, needling and removing non-needled fibres may be repeated (e.g. 2 or 3 times) to give a multicoloured pattern prior to the overall needling. To ensure a web of uniform thickness the last cycle may invalue needling all previously uneedled areas. A previously consolidated web may be applied prior to the overall needling. This needling may raise a pile on the fabric. As shown the fibres are deposited from ducts 19 which extends across the width of the fabric and are spread by a driven feed roller 22. A brushing roller 23 lessens the fibres deposited on the uneedled areas and facilitates their removal up duct 24 by suction caused by fan 20. The needle boards 6, 7 8 are reciprocated by the rotation of eccentric disk 12. The depth to which the needles penetrate may be adjusted by gear 13 which adjusts the position of mounting block 14 within guides 15. The webs and the staple fibres may comprise polyamide, polypropylene or polyacrylic ester.

Title: Improvements in the separation of iron, cobalt and zinc from solutions of chlorinated roasted burnt pyrites
IPC: C22B3/44
Filed: 1953-05-14
Abstract: The contents of iron, cobalt and zinc are separated in a continuous operation from solutions of the product obtained by roasting and subsequently chlorinating burnt pyrites, by passing the solution through an iron precipitating stage where the iron is precipitated by the addition of a suspension of a precipitant of a concentration of 10 to 22 DEG Be at a pH of 3.5 to 4.0, a cobalt precipitating stage employing a 5 to 10 DEG  Be precipitant at a pH of 3.7 to 4.2 <PICT:0729001/III/1> and a zinc precipitating stage employing a 6 to 12 DEG  Be precipitant at a pH of 6.5 to 7.5, each stage including a thickener in which the slurry in that stage is concentrated to a solid content of at least 800 g.p.l., and a filter for the concentrated slurry.  The bivalent iron in the starting material may be oxidized partially by air and partially by chlorine, such oxidation reducing the proportion of zinc in the precipitator in the iron precipitating stage.  As shown in the flow sheet, the iron precipitating stage is at 40 to 60 DEG  C. and calcium carbonate is employed as the precipitant.  Barium carbonate may also be used.  The slurry is passed to a thickener and a rotary filter, and the filter cake from the latter may be reslurried in water and refiltered.  The supernatant solution and waste water are passed to a cobalt precipitating stage where the solution may be again oxidized with chlorine and precipitation effected with zinc hydroxide as shown or calcium hydroxide or carbonate; after passing the slurry through a thickener and a filter, the cobalt-containing precipitate is withdrawn and the remaining solution passed to the zinc precipitating stage where a precipitant such as calcium hydroxide or sodium carbonate is employed, the temperature of this stage being 65 DEG  to 85 DEG .  The zinc hydroxide precipitate is recovered.
