Title: Process for the separation of alkali metal azide
IPC: C01B21/08
Filed: 1975-03-27
Abstract: 1458951 Separation of alkali metal azide CANADIAN INDUSTRIES Ltd 27 March 1975 [24 April 1974] 12877/75 Heading C1A An improved method of separating solid particles of basic alkali metal azide (alkali metal azide/alkali metal hydroxide double salt) from a liquid ammonia/alkali metal azide solution comprises contacting the solution containing suspended basic azide particles with an immiscible mineral oil or silicone oil of greater density than the said solution, allowing the mineral oil phase and the solution phase to form an interface, whereby the suspended azide particles traverse the interface by gravity, and are suspended in the oil phase. The basic alkali metal azide-containing oil phase is contacted with an aqueous phase, allowing the suspended azide particles to cross the interface by gravity, preferably passing through a screening means, having openings corresponding to the mean particle size of the azide particles, interposed at the oil/water interface, and to dissolve in the aqueous phase. The mineral oil is preferably an aliphatic mineral oil. In one embodiment (Fig. 1), the alkali metal azide/liquid ammonia solution containing suspended azide particles is introduced into a pressure vessel 1 and the mineral oil is introduced into 1 by line 3, and passes out via line 5 with the suspended particles of basic azide. The water is introduced in an atmospheric vessel (8), provided with outlet line 12 for removal of aqueous alkali metal hydroxide and alkali metal azide. In a further embodiment (not shown), the process takes place entirely within a closed pressure vessel, with inlet lines for introduction of liquid ammonia/alkali metal azide solution containing suspended basic azide particles, and/ or introduction of water, with an inert mineral oil phase between these other phases.

Abstract: 378,070. Electrical musical instruments; valve generating circuits inductances. COUPLEUX, E. E., 24, Rue Esquermoise, Lille, Nord, and GIVELET, J. A. M. V. de P., 24, Rue Bois-le-Vent, Paris, both in France. May 1, 1931. No. 12925. Addition to 359,967. [Class 88 (ii).] An electrical musical instrument with thermionic valves, oscillatory circuits and keys, according to the parent Specification, is modified by the provision, Fig. 1 (not shown), of a filter and a primary winding on a transformer for each unit comprising a valve, oscillatory circuit and key, interferences between harmonics being thereby reduced. Each transformer may have its own amplifier, or may be grouped on a single amplifier with the single loud-speaker. In the arrangement shown in Fig. 2, a single valve L will give two different notes. With the key T<1> in the position shown, the grid is negatively polarized and depression of the key T causes the oscillatory circuit C to supply the normal note through the filter B to the loud-speaker D. Depression of the key T<1> depolarizes the grid by making the short-circuit at M<1>, and throws in the grid capacity E and resistance R by breaking the contact at M, thus producing the second note with the aid of a singing grid. Bi-grid valves, Figs. 3 and 4 (not shown), may be arranged to produce a single variable note of pure tone. Fig. 5 shows a transformer adjusting intensity for a group of valves. Each valve supplies a primary winding e on one of four fixed armatures N. The core H, carrying the single secondary S, has extensions 1 .. 4 at each extremity and is adjusted by rotation about its axis. Oscillating circuits are merely shortcircuited during periods of silence, instead of cutting off the plate current, to avoid chattering in the loud-speaker. The expression of a note or of a group of notes is regulated according to the extent of key-depression by means of an adjustable circular resistance, Fig. 7 (not shown), or a series of fixed resistances, Fig. 8 (not shown).

Title: Artificial protein-containing fibres and method of production  thereof
IPC: D01F6/60
Filed: 1971-05-04
Abstract: 1325271 Artificial protein-containing fibres FUJII KEORI KK 4 May 1971 [25 Sept 1970] 13086/71 Heading B5B [Also in Division C3] Artificial protein-containing fibres are prepared by melt spinning a product obtained by precipitating a high molecular bonded product of animal fibre protein and nylon from an acid solution. The method involves the steps of (a) dissolving and decomposing an animal fibre in an acid solution (e.g. concentrated H 2 SO 4 ) (b) adding and dissolving nylon staple or powder to the solution of animal fibre protein thus obtained (c) reducing the solubility of the protein and nylon mixture in the solution by the addition of water or dilute acid thereto or by cooling and thus precipitating a high molecular bonded product of animal fibre protein and nylon which is filtered and dried and (d) melt spinning the product thus obtained. The ratio of nylon to animal fibre protein in the product may be 0À3 : 1 and preferably is from 1À5 : 1 to 2 : 1. The product may be blended with a thermoplastic resin (e.g. polyamide or polyester) prior to melt spinning. More effective bonding between the protein and nylon molecules in the high molecular bonded product may be obtained by (a) treating the animal fibre before dissolution in the acid solution with a compound containing active chlorine (e.g. sodium hypochlorite or dichloroisocyanuric acid) or an aqueous solution of peracetic acid, performic acid or hydrogen peroxide to break the disulphide bonds in the cystine groups of the animal fibre; (b) heating and stirring the dissolved animal fibre before adding nylon thereto; or (c) treating the acid solution of the nylon, animal fibre mixture with chlorine gas or iodine (preferably prepared in situ from sodium hypochlorite and potassium iodide respectively). In examples artificial protein fibres are prepared by melt spinning products obtained by dissolving wool, cashmere beard hair, human hair or collagen obtained from feathers or leather in concentrated H 2 SO 4 , adding nylon staple to the acid solution and heating to dissolve the nylon, and diluting and/or cooling the solution to precipitate the product.

Impedances are measured by forming an undamped tuned circuit and exciting free oscillations therein by periodic impulses, the oscillating voltage produced being fed into a mixer into which are also fed oscillations from a reference generator, so that a difference frequency is produced which is measured. An inductance Lx to be measured is connected to the terminals AB of a pulse generator I in parallel with a fixed condenser and a variable condenser Cn. The oscillating voltage produced in this tuned circuit is supplied through a low-capacity Cv to a diode D, the D.C. component, indicating the Q-value, being measured by an instrument M1. The high-frequency component is fed through a separator II to a mixer III, into which also is fed the oscillation voltage from a reference generator IV. The diode D and instrument M1 may be omitted if a simultaneous measure of Q-value is not necessary. A difference frequency is produced in the mixer III and is indicated by a magic eye M2 and a loud-speaker T. This beat frequency is reduced to zero by varying the capacity of the condenser Cn, which is calibrated to indicate the value of the inductance or its deviation from the desired value.

Abstract: 1,138,557. Controlled rectifier. INTERNATIONAL RECTIFIER CORP. 22 March, 1967 [12 May, 1966], No. 13348/67. Heading H1K. A controlled rectifier (Fig. 1) which can be switched on and off by positive pulses of different magnitudes consists of a PNPN layer structure with main current electrodes 10, 11, a gate electrode 13 on the inner P layer, and a second gate electrode 12 connected to the outer N layer via superposed N and P layers. With the device biased as shown a small positive pulse applied to the common gate connection 20 switches it to the conductive condition. If now a positive pulse sufficient to break down junction J 1  is applied holes injected across junction J 2  reduce the injection efficiency of junction J 5  to such an extent that the current falls below a holding value and the device switches off. The opposing effect of the bias on gate electrode 13 is however overcome only if that electrode is sufficiently remote from the other side of the second gate structure and the values of resistor 19 and the lateral resistance of layer P 2  are sufficiently high, but if the gates are independently connected so that gate 13 is unbiased these considerations no longer apply. For optimum effect the areas of junctions J 1  and J 2  should be at least 75% of that of junction J 5 .
