Title: Process for the production of sodium potassium or ammonium hexacyanoferrate-ii
IPC: C01C3/12
Filed: 1973-03-27
Abstract: 1428542 Sodium, potassium and ammonium hexacyanoferrates-II DEUTSCHE GOLD-UND SILBER-SCHEIDEANSTALT 27 March 1973 [27 March 1972] 14544/73 Heading C1A A solution of calcium hexacyanoferrate-II is reacted with a solution of an iron-II salt to form the insoluble iron-II hexacyanoferrate-II which is water washed until free from Ca<SP>++</SP> ions and then reacted with sodium, potassium or ammonium cyanide to form the corresponding hexacyanoferrate-II. If desired, a flocculant may be added to the iron-II-hexacyanoferrate- II prior to its separation and washing. The reactant solutions may be pure or commercialgrade. The iron-II salt solution may be a solution of ferrous chloride or ferrous nitrate or a spent pickling bath liquor, and the cyanide solution may be an industrial solution from an electroplating bath. The calcium hexacyanoferrate-II solution may be an unfilterable solution such as that which accumulates during the reaction of HCN, iron-II-salt solutions and calcium compounds. The production of the iron-II-hexacyanoferrate-II may take place at a temperature between 10 and 100 C. The temperature of the washing water may be between 10 and 95 C., but is preferably at room temperature. The reaction of the iron-II- hexacyanoferrate-II precipitate with the cyanide solution may be carried out at 20- 100 C., if desired using the iron salt in slight excess. All reactions may be carried out in conventional mixing vessels using stirrers. The washing of the flocculated iron-II-hexacyanoferrate-II may be carried out continuously with water in counter-current, any calcium salts being removed in the water stream and the purified iron-II-hexacyanoferrate-II settling at the bottom of the washing apparatus.

Title: Circuit interrupter
IPC: H01H33/873
Filed: 1971-05-13
Abstract: 1320421 Gas blast circuit breakers MERLIN GERIN 13 May 1971 [26 May 1970] 14668/71 Heading H1N A gas blast circuit breaker has a pair of longitudinally axially aligned arc extinguishing chambers 26, 28 each having a pair of relatively movable series connected contacts, 36, 82, contacts 82 being movable along the respective axes of control arrangements 42, 95, which axes are offset relative to one another so that the controls overlap at the confrontation of the two chambers and thereby reduce the overall length of the circuit breaker. Conductors 16, 18 are normally electrically connected through closed contacts 36, 82, conductive plates 32 and 72. When a valve 24, connected to source of compressed gas 22, is operated, high pressure gas passes through lines 56 to push pistons 98 against the bias of springs 99. The piston 80 is now exposed on one of its sides, through orifice 90, with the low pressure chamber 10 through space 92, so that the high pressure within chambers 26, 28 pushes piston 80 down. The piston engages the collar 84 on contact 82 causing the contacts to open. The high pressure in line 56 also forces piston 46 of valves 42 down so as to open the respective exhaust valves so that a gas blast through the nozzle contacts extinguishes the arcs formed. A valve 62 seating against an orifice 70 slowly opens in response to the high pressure acting on the control device 54 so that the valves 42 only remain open for a relatively short period. The gas which may be SF6 is compressed and recirculated between the low pressure earthed metal chamber 10 and the chambers 26, 28. Capacitors 100, resistors, or auxiliary contacts may be connected across the chamber end plates.

Title: Friction clutch for gear changing mechanism
IPC: F16D41/00
Filed: 1935-05-20
Abstract: 440,541. Free-wheel clutches. RAMBAUSEK, H., 14A, Triftstrasse, Eberswalde, near Berlin. May 20, 1935, No. 14710. Convention date, May 19, 1934. [Class 80 (ii)] A friction free-wheel clutch for variable-speed gearing comprises two parts, one of which is operated by an external manual control while the other part is operated automatically according to the flow of power in the gear. In the form shown in Fig. 1, drive is transmitted from the shaft a to the shaft b either through the free-wheel clutch i, k and gears c, d, or at a higher gear ratio through gears e, f, g, c, d, and countershaft h with the clutch i, k overrunning. The clutch member k is splined to a sleeve k<1> connected with lost-motion by lugs k<3>, k<4> to an internal gear k<2> integral with the gear c. Planet pinions n rotatable in a flange on the sleeve k<1> engage the internal gear k2 and are formed with reversible screws o threaded into the clutch member k. When the gear c is speeded up by throwing in the countershaft clutch f the lugs k' gain on the lugs k<3> and the member k<2> is thus permitted to rotate relatively to k<1> so that the gears n and screws o are rotated, and the clutch member k is withdrawn from engagement. When the countershaft clutch f<2> is disconnected, the compression spring p returns the clutch member k into engagement and the lugs k<3>, k<4>, to their original relative position. The clutch i, k can be disengaged altogether by sliding the member i by means of the lever i<2> In a modified form, Fig. 3, (not shown), the countershaft is arranged to give a reversed drive which is applied to the member k<1>, and a plate clutch is substituted for the cone clutch i, k. Friction clutches may be used to bring in the countershaft drive. In the form shown in Fig. 4, the clutch member k is threaded directly on the gear c at k<5> and is urged towards the engaging position by inclined springs 9. The manually controlled clutch-member i is connected by springs to a ring i<4> operated by a drag ring i<5> displaceable axially by a face cam i rotatable by a hand wheel i'. The ring i<5> may be moved so far that the clutch is permanently disengaged. Stops may be provided to limit the engaging pressure produced by the screw k<5>. In the form shown in Figs. 5 and 7, the clutch member k is withdrawn by an electromagnetic clutch r operated by contacts w<2>, w<3> on the lugs k<3>, and a contact w<1> on one of the lugs k<4>. A switch w<6> connected to the prime-mover control is arranged so that when the direction of movement of the prime-mover is reversed, the switch w<6> moves, say, from the contact w<4> to the contact w<5>, thus making the contact w<2> live instead of w<3>. Free-wheeling is thus possible for either direction of rotation of the driving shaft a. A master switch w' is provided which, when broken, prevents disengagement altogether.
