Title: Method of evaluating irregularities of advancing textile materials  such as laps rovings or yarns and apparatus for carrying out same
IPC: D01H5/42
Filed: 1970-03-04
Abstract: 1307702 Measuring permeter of a movement material electrically STATNI VYZKUMNY USTAV TEXTILNI 4 June 1970 [6 March 1969 (2)] 10330/70 Heading G1N Irregularities in a parameter, e.g. weight or volume, of an advancing material, e.g. laps or yarns are detected by a transducer 1 whose output is proportional to the deviations of a notional mean value set by a potentiometer 6 this signal being passed through one of a number of filters 3, 4, 5, 20 amplified at 7, optionally corrected for sign and/or squared at 10, and integrated at 13 over a predetermined time, the signal prior to integration having been attenuated relative to the time of integration and to a limitation factor of the integrator by a voltage divider 12 so that the display on a meter 16 is representative of the desired output. A number of different measurements are made possible by the choice of the filter 3, 4, 5, or 20. For measuring mean deviation circuit 4, i.e. a straight connection is selected. The attenuated signal is integrated over a time determined by a relay 15 and the output is passed to meter 16 via switch 17.  To measure the deviation of the next section of material the last value is utilized being fed to the amplifier 7 via switch 18 together with an adjusting voltage from potentiometer 8 so that for this section measurements are made relative to the mean value found in the preceding section. Filter 3 is a high pass filter, eliminating low frequency components from the input signal. Filter 5 is a low pass filter which is used when long sections of the yarn are being evaluated, this filter having the effect of notionally cutting the yarn into short sections, the mean values of these sections being utilized. Filter 20 is a band pass filter such as to eliminate high and low frequency components from the signal utilized.

Abstract: 863,348. Purifying sea water &c. by freezing. METALURSKI INSTITUT. March 25, 1959, No. 10438/59. Class 29 Salt water, e.g., sea water, previously concentrated to a density of 10-15 degrees BÚ, is frozen with admixture of small air bubbles until the density of the liquid residue reaches 16-22 degrees BÚ and the ice crystals are then separated from the residue and rinsed with pure water. A charge of previously concentrated salt water is introduced into tank 1, refrigerated by jacket 3, and cold air is withdrawn from the top of the tank by suction tubes 7 through apertures 9 'and injected into the liquid as fine bubbles. Suction tubes 7 also carry agitators 8. The ice crystals together with some concentrate are then withdrawn from tank 1, by pump 12 and supplied to centrifruge 14. Some of the centrifuged concentrate is led through pipe 15 to waste or for the preparation of salt and the rest is led back to the tank 1 for the next batch by pipe 17. The ice in the centrifuge is then washed by cold pure water from heat exchanger 20, the effluvient being supplied to tank 1 also by pipe 17. The ice is passed from the centrifuge through pipe 21 and is melted in heat exchanger 20 by heat exchange with incoming salt water in coil 23, the melted ice being led off partly through pipe 27 for use as fresh water and partly through pipe 29 to the centrifuge for rinsing the next batch of mixed ice and concentrate. The cooled salt water from coil 23 is led to tank 1 through pipe 24 so as to constitute, along with the residue from the previous batch, the separated concentrate, and the rinsing water, the next batch to be concentrated.

Title: Improvements in fuse-cords for grenades
IPC: F42C9/10
Filed: 1917-04-16
Abstract: 141,744. Dewandre, A., and Laminne, J. de. June 15, 1916, [Convention date]. Projectile fuses.- Relates to grenades fired by means of a fuse cord p tipped with inflammable paste r at the end, which is inserted into a percussion cap holder. According to the invention, the cap-holder h is provided with elastic limbs h' for gripping the percussion cap o. With this arrangement, weak percussion caps may be used. The fuse and its appendages, are inserted through a bottom orifice closed by a screw-plug a<2>. Fuses for flares of the kind which are dropped from aircraft and comprise a flare composition and a parachute at opposite ends of a casing from which the parachute is expelled by means of an explosive charge ignited by the fuse which also ignites the flare. A fuse, according to the invention, can be set for various times depending upon the height of the aircraft, in order that the flare may come into action at a predetermined height from the ground. As shown, the casing of the flare is made in two parts A, A<1> secured to a dividing partition B by set-screws a and containing respectively the flare composition C and the parachute Q. The end of the flare composition is covered by a time fuse comprising a fixed part D provided with an incomplete annulus F of timefuse composition and an inner rotatable part E carrying a spring-striker H for igniting the fuse at the moment the flare is dropped. This striker is normally uncocked and interlocked with a handle K by means of a knob h<1> on the striker and a pivoted catch K<1> which is confined by the socket E<2> on the rotatable part E. The handle is held in place bv a trigger M pivoted to the handle and engaging beneath a shoulder e<4> on the socket E; and this trigger is locked by a transverse pin 0. To drop the flare, the pin 0 is first removed, then the trigger M defected, whereupon the flare drops off the handle and cocks the striker H. As soon as the catch K<1> is released by the socket E<2>, the striker slips away from the handle and fires a percussion cap j, which ignites the annulus of the time-fuse composition F through a flash passage e<2> which can be set for various times by a rotation of the part E. A yielding spring catch g stops the part E at every five seconds of setting. When set for zero, the flash passage is shut off from the annulus E, but still opposite the vent e<O> in the pointer E‹ on the part E : and thus any accidental ignition of the percussion cap j is vented off safely. After the appointed time, the annulus F transmits the flash to a charge f<1> which ignites the flare composition C; and the ignition is then communicated by a tube P to an annulus charge p<2> which expels the parachute Q and the covering cap W at the end of the casing.

Abstract: 1,044,181. Filling containers; endless conveyers. ETABLISSEMENTS KRIEG & ZIVY. March 18, 1963 [March 19, 1962], No. 10626/63. Headings B8A and B8C. [Also in Division H1] Containers, for example squeeze tubes, to be filled are mounted transversely on a strip (Fig. 1, not shown), and are drawn by grasping means 64 (Fig. 6, not shown), engaging successive containers through a machine which includes filling nozzles, funnels or guides 80 moving with the containers to fill them, and a closing station 82, 84. Loops 5, 6 (Fig. 2, not shown), holding the containers on the strip may be cut from the strip, or the strip may be formed of transverse members 9 (Fig. 3, not shown), joining spaced pairs of strips. As a further alternative (Fig. 4, not shown), the containers may rest on a flat strip and be secured at each end by tapes secured to the flat strip between the containers and passing over them. In the machine described, the grippers 64 feeding the containers 1 and the strip 2 are carried by an endless chain. The strip 2 is twisted, to dispose the tubes vertically, and the tubes are then cleaned at 68 by air-blowing and suction devices 70, 71. They then pass beneath a set of moving filler nozzles 80, between belts 82 for flattening the skirts of the tubes, and through a station 84 which closes the opposite ends of the tubes by shaping. Stoppers are then fitted on the tubes at 86 and the folds are crimped and the tubes marked at 88. The band of containers may then be fed to form layers in a packing case. Alternatively, the band may be cut into lengths each containing several tubes. In the form shown, however, the tubes are pushed from the band of plungers 97 moving with an endless member 96 and operated by a cam 98. The tubes are thus pushed either into individual containers on a conveyer 92 or into containers for receiving a number of the tubes. The containers may be secured to the conveyer 92 and may be erected while secured to it. Paper inserts may be inserted with the tubes into their containers.

Title: Production of beryllium
IPC: C25C3/34
Filed: 1927-04-20
Abstract: 287,734. Marks, E. C. R., (Kemet Laboratories Co., Inc.). April 20, 1927. Beryllium, obtaining. - Beryllium is obtained by electrolysis of anhydrous beryllium chloride, substantially free from oxide, in a bath of fused sodium chloride or other halogen salt of a metal electropositive to beryllium. Beryllium chloride is prepared by heating beryllium, oxide with carbon in an atmosphere of chlorine, or with carbon tetrachloride and chlorine, or with phosgene, moisture and air being excluded. The beryllium chloride sublimes into the cooler part of the chamber. Electrolysis takes place in a cell which is connected as cathode; the cell may be of iron but is preferably of nichrome or of an iron-chromium alloy containing at least 5 per cent and preferably 20 per cent of chromium. The cell should be of a size just to hold the charge and the anode. The charge may consist of 5 kgm. of beryllium chloride and 25 kgm. of sodium chloride. The cell has a dome-shaped cover having a small opening near one edge for the introduction of inert gas and a large opening for the removal of excess gas and chlorine, the latter opening also serving for the introduction of beryllium chloride. The anode passes through the centre of the domet and is surrounded by an asbestos ring. The sodium chloride is introduced first and is heated by a gas flame until it begins to melt. Hydrogen is then passed in and beryl. lium chloride added slowly. Electrolysis is started at a temperature of 730‹ C. which is raised to 820‹ C. towards the end of the run. Alternatively the beryllium chloride may be added in small quantities and a temperature of 800‹ C. maintained throughout. Completion of the electrolysis may be tested by removal of a little of the molten salt and testing its solution for acidity, neutrality indicates completion. On completion, excess electrolyte is decanted off and the beryllium is scraped out and protected from oxidation while hot by a thin coating of salt thrown over it. The mass when cold is broken up and leached with cold water until free from soluble matter and is finally washed with alcohol, preferably anhydrous, and air dried. The metal, in the form of crystalline spangles is pressed in steel dies under several tons pressure into rods or discs. These are heated to 1300‹-1450‹ C. in a closed crucible, with barium chloride or a mixture of barium chloride with 10 per cent barium fluoride until the particles of metal coalesce. Specification 287,762 is referred to.
