Title: Process of dissociating zirconium ores
IPC: C01G25/00
Filed: 1927-11-02
Abstract: 282,023. Rhenania-Kunheim Verein Chemischer Fabriken Akt.-Ges. Dec. 13, 1926. [Convention date]. Zirconium oxide.-Zirconium ores are admixed with an alkaline earth carbonate, oxide, or hydroxide, and with a halogenide of an alkali or alkaline earth metal and subjected to a sintering process at say 1200‹ C. in the absence of carbon or carbides, preferably in a reverberatory furnace such as a revolving furnace. Zirconium oxide soluble in acids is thereby produced. The presence of steam, which may be supplied as such or be produced by the combustion of fuels rich in hydrogen is advantageous, since it allows lower temperatures to be employed. According to examples, a mixture of ore, fluorspar, and calcium carbonate is finely ground and heated to 1200‹ C., and a ground mixture of ore and calcium carbonate is moistened with calcium chloride lye and calcined at 1250‹ C.

Abstract: 665,964. Protective cut-out systems. ANDERSON, BOYES & CO., Ltd. Sept. 27, 1950. [Nov. 15, 1949] No. 29268/49. Class 38 (v). An earth-leakage protective arrangement for polyphase A.C. systems comprises a contactor 1, a core-balance transformer 2, a thermionic relay 4 arranged normally to conduct so as to energize the operating coil 5 of the contactor which is thus closed, and a biassing network connected to the secondary 6 of the' transformer 2 so as to produce negative biassing of the relay 4 on fault, so as to open the contactor. The secondary 6 is normally connected to the grid of relay 4 and a condenser 15 over a changeover switch 13, which on opening of contactor 1 moves over to its other position simultaneously with the closing of a switch 17, thereby connecting the secondary 10 and a transformer 8 in series with the fault X and a potentiometer 18 over the switch 17. The negative bias on the grid is thus maintained by the voltage across the potentiometer so that the contactor 1 remains open so long as the fault persists. In a modification (Fig. 2, not shown), the changeover switch 13 is omitted and the secondary 6 is permanently connected in the biassing network. A lamp or other signal device may be connected in the biassing network, and the relay 4 may include one or two gas filled triodes or thryatrons.

[Class 74 (ii).] Relates to means for supplying wrap yarn to selected needles and to means for controlling the knitting cams and other needle actuating devices of a circular machine provided with a stationary needle cylinder. Patterning is effected by pivoted wrap fingers which can be moved across the needles by cams selectively operated by an intermittently rotated trick wheel carried by the rotating cam ring 8. The knitting cams include three radially movable cams 62, 64, 66, Fig. 4, which effect the clearing of the previously formed loop, the raising of the needles to receive wrap yarn, and the lowering of the needles to make a fresh stitch, the main yarn being supplied to the needles at the point 72. The cam 64 is mounted at the end of a slide 76, Fig. 2, which can be moved radially outwards, to withdraw the cam from a position in which it engages all the needles to that in which it engages only long-butted needles or to a position in which it misses all the needles, by a relatively stationary cam 98, which can be rocked to the desired position by a stepped cam disc. The cam 64 is retained in the desired position, against spring action, by the engagement of a pin 88 on a pivoted lever 90 with notches 84 on the slide, the engagement of cam 98 with a screw 96 on the lever 90 effecting release of the cam when required. A projection 104 is provided on the slide 76 to engage a screw 106 on a pivoted arm 108 and positively withdraw the cam 62 when the cam 64 is moved to its extreme outer position. The cam 66 is mounted similarly to cam 64 a single notch 120 being provided in its retaining lever 124 to hold the cam in inactive position when desired. A lowering picker 136 and a switch cam 192, also carried by the cam ring 8, are operated by the circumferential movement of a slide 150, Fig. 6, under the control of a relatively fixed pin 172 which can be moved vertically by cams on a cam disc 175 to engage the depending portion 165 of a member 154 associated with the slide. Movement of the slide 150 to right and left respectively during the oscillating of the cam ring, rocks the lever 138 and a shaft 190 to lower and raise the picker 136 and the switch cam 192.

Title: Improvements in and relating to the production of polypyridyls
Inventor: JUBB ANTHONY HOWDEN
Filed: 1958-09-18
Abstract: Polypyridyls are obtained by heating a salt of pyridine or a salt of a polypyridyl.  The free base i.e. pyridine or a polypyridyl, may be present in addition to the salt.  Preferably the reaction is carried out in the presence of a metal halide which forms complex compounds with condensation products of pyridine and polypyridyls, for example, halides of iron, zinc, copper, cobalt and nickel.  Preferably the salt of pyridine or a polypyridyl used as starting material is the hydrochloride.  The preferred temperatures for carrying out the process are in the range 270-340 DEG C. and the process may be carried out under elevated pressure.  The surfaces of the reaction vessel which are in contact with the reaction mixture should be made of a material which is resistant to corrosion, e.g. tantalum. Examples are given of the preparation of 221-di-pyridyl and 2,21,211,2111-tetrapyridyl.
