Title: Apparatus useful inter alia for the production of finely divided metal oxides
Inventor: MAS ROBERT JEAN
IPC: C01G23/07
Filed: 1962-07-17
Abstract: A burner device for use inter alia in the preparation of finely-divided metal oxides by the method of Specification 1,047,713, comprises a metallic tubular pre-combustion chamber of which one end is in open communication with a metallic, tubular mixing chamber and having a common axis therewith, the end of the pre-combustion chamber furthest from the mxing chamber having a centrally located inlet conduit directed axially into the pre-combustion chamber and at least one annular orifice surrounding said inlet conduit, for feeding separately to the pre-combustion chamber a free oxygen-containing gas and a combustible gas, a plurality of conduits of small diameter opening radially into said mixing chamber for feeding a mixture of metal chloride vapour and oxygen to the mixing chamber, and means for contacting the exterior of the pre-combustion chamber and mixing chamber with a cooling fluid.  In Fig. 1, for example, oxygen is passed into a pre-combustion chamber C through inlets g1 and g2 passing fins h2.  Carbon monoxide or other inflammable gas is passed into C through inlet k1 <PICT:1047714/C1/1> passing fins k2 and k3. Nitrogen may pass through l1 into C.  The gases are ignited and the burnt gases violently directed into mixing chamber D where they meet jets of, for example, titanium tetrachloride and excess oxygen from m4 and m5 and similar peripheral inlets, which mixture has been introduced at m1 and passed through pipes thermally insulated from the cooling fluid e.g. oil or water, entering at n1 and leaving at n2.  The reaction forming the oxide starts in the burner and is carried to completion in the oxidation furnace.  The burner may be of aluminium.  Chambers C and D may form a Venturi tube with inlets m4 and m5 at the neck. Modifiers such as steam may be added to the oxidizing gas or the monoxide, or chlorides, such as aluminium or silicon chloride may be added to the stream of volatilized chloride. Oxides of titanium, zirconium, aluminium, tin, chromium, iron, silicon, hafnium and niobium may be made in the burner.

Title: A method and device for closing and sealing of valves in valve bags
IPC: B65D30/24
Filed: 1947-09-08
Abstract: 627,950. Paper or like bags. BILLERUDS AKTIEBOLAG. Sept. 8, 1947, No. 24664. Convention date, March 7, 1944. [Class 94(ii)] A method of closing and sealing the valve of a paper or like bag comprises lining the valve with a sleeve 1 which projects only a relatively short distance from the valve opening, fixing a comparatively narrow sheet metal strip 2 on or immediately above the upper wall of the sleeve with one longitudinal edge parallel to and adjacent the outer edge of the sleeve, folding the strip about a suitably indicated line parallel to its longitudinal edge downwardly and inwardly so as to enclose the sleeve within the fold, and crimping the folded strip with a pair of sealing tongs. As shown, the strip is angular in cross section, the angle forming the folding line, and is hingedly connected to the sleeve by an enclosing sheet 4 of paper. In a modification a flat strip rests directly on the sleeve and the folding line is formed by a series of perforations in the strip. In a further modification a triangular tongue formed in the inner half of the strip is forced in folding through a corresponding aperture in the outer half of the strip and is then folded about its base. It is stated that the tongue and aperture may be formed by the sealing tongs.

If the difference is greater than the threshold value a fault signal is transmitted via register 477 to actuate removal of a defective cigarette by air blown through a pipe 452. Fig. 4 (not shown) includes an arrangement whereby the two pulse generators are substituted by a circuit sensing minima and maxima of the evaluated signal.

Abstract: 996,640. Fault testing. SHINKO DENKI KABUSHIKI KAISHA. June 22, 1963, No. 24920/63. Heading G1U. Cable insulation testing apparatus comprises a transformer 3 of drooping regulation characteristic energized from mains over contactor 2 operated by pressel switch 17 to feed bridge rectifer 4 charging capacitor 5. The voltage of the latter is applied over resistor 6 to a resistive voltage divider tapped successively at 8, 9,10 to develop a diminishing range of test voltages. A pressel switch 18 enables relay 21 to be energized after relay 16, and time delay relay 19 is energized across coil 21 to open contacts 20. Relay 21 closes contacts 22, 14, 23 to hold relays 19, 21 over 22, to connect the lower terminal of voltage divider 7 to test terminal D over 14, and to energize time delay relay 24 over 23 to close contacts 25, 26 in timed succession to apply the voltage at tap 9 and shortly afterwards that on tap 10 to test terminal C over current relay 13, operative to close contacts 12 and connect the upper end of the voltage divider over variable resistive 11 to terminal C. In operation, pressel switch 17 closes contacts 2 to energize the transformer 3 and charge capacitance 5; the contacts holding closed over contact 20. Pressel switch 18 then energizes relay 21 to close contacts 22, 14, 23, and relay 19 to open contacts 20 after a time delay; relays 19, 21 holding over 22. Relay 24 operates to apply an initial test voltage from tap 9 to the test terminals for a short time to rupture any faulty insulation, and a lower voltage is applied from tap 10 to maintain the breakdown until the leakage current reaches a critical level. Relay 13 then operates to apply a current over resistors 6, 11 to weld the conductors together at the fault point; magnitude being limited by a drooping transformer characteristic. In the absence of fault, relay 13 is inoperative, and after the test cycle relay 19 operates to open contacts 20 and release relay 16 thus de-energizing the transformer in readiness for a further test. Fault position may be located by measuring line resistance between the test point and the fused fault in the cable

Abstract: <PICT:0412805/III/1> Activated fuller's earth is prepared by subjecting an aqueous suspension to electrodialysis.  The initial conductivity of the suspension may be increased by addition of a small amount of an acid or salt.  In the apparatus shown the suspension is introduced into the middle compartment of a three-compartment cell, and is agitated by an inert stirrer 5. Carbonic acid gas is introduced from a ring 6 to form the electrolyte.  The operation may be conducted under gas pressure, the excess carbonic acid gas being returned in a cycle.  Waste gases containing carbonic acid may be employed.  In a modification, the stirrer 5 forms the anode of a two-compartment cell.  The activation is continued until the suspension attains a constant minimum resistance.  By the use of a filter diaphragm, e.g. for the cathode diaphragm, water may be simultaneously removed from the suspension, the process then being known as "electro-ultrafiltration."
