Abstract: 1,174,002. Mechanical toys. W. P. CARROL. 19 Jan., 1967, No. 2975/67. Heading A6S. [Also in Division G1] The speed and/or steering of a toy vehicle is controlled remotely by varying the intensity of light falling on a photoelectric device on the vehicle. A toy racing car is provided with photocells SME, DME Fig. 8 which control the currents through a steering motor SM and a drive motor DM in accordance with the amount of light they receive from corresponding lamps (SML, DMY), Fig. 7, (not shown). To avoid light from each lamp affecting the wrong photocell, SML is a fluorescent tube and SME a selenium cell respectively producing and sensitive to wavelengths in the range 700-700 nm while DML is a tungsten lamp and DME a silicon cell each provided with a filter to work on wavelengths >725 nm. Current for the motors DM and SM is derived from the track which comprises alternate positive and negative strips 42, 44 (to which 12 volts is applied) by brushes Figs. 5 and 5g (not shown) which are laid out in the form of an L. To switch the car from forward to reverse and vice versa, switch 84 is closed. This applies 50 volts to the track, which is sufficient to step on the ratchet relay RR to reverse the direction of motor DM. Steering. The shaft of the motor SM carries an offset pin 38, Fig. 2, which cooperates with a crown wheel 36 fixed on a steering shaft 34. The steering crank 24 is biassed against a stop 26 by a rubber band 28, but provided the speed of motor SM is sufficient it is urged away from the stop by a cord 32.

Abstract: 284,677. Telefunken Ges. f³r Drahtlose Telegraphie. Feb. 3, 1927, [Convention date]. Copying-telegraphs. -In order that the telegraphic transmission of a series of pictures may proceed without interruption, two picture-carrying drums are used alternately at each station. Thus at the transmitting station a drum 3, which is subject to rotary and axial motion, is explored by a light pencil reflected by the picture elements on to a ring- shaped light-sensitive cell 5. Meanwhile the next picture for transmission is fitted to the drum 3<1>, and this drum is then clutched in correct phase to the synchronous driving motor. When the picture on drum 3 has been dealt with the mechanism for imparting axial motion to drum 3<1> is put into operation, and at the same time the optical system 5, 6, 8 is swung so that it may operate on the drum 3<1>, as indicated in dotted lines. A corresponding arrangement is adopted at the receiving station. As shown in Fig. 5, light from the source 8 may travel axially for a certain distance and be then deflected by a prism 16, in order to shorten the part of the optical path which is subjected to angular movement.

Title: Process for separating niobium and tantalum from each other
IPC: C01G33/00
Filed: 1957-02-01
Abstract: Niobium and tantalum are separately recovered from an oxidic source material by treatment with chlorine in the presence of carbon whereby the niobium is converted into its oxychloride and the tantalum to its pentachloride, and the chlorination products are thereafter either subjected to fractional condensation or wholly condensed and split up into fractions by sublimation.  The source material may be a mixture of the oxides or an ore concentrate or slag.  Temperatures of 400 to 1000 DEG C. are employed for the chlorination and the chlorination gases are rapidly cooled to prevent after-reaction, by dilution with a cold inert gas such as recycle gas free from chloride or by the injection of a liquid chloride such as silicon, titanium or carbon tetrachloride.  The added chlorides, which are completely vaporized, may be separated by condensation after the condensation of niobium and tantalum.  The sublimation of the mixed chlorination products is preferably effected under reduced pressure of about 0.1 mm. of Hg. On gentle heating in the absence of moisture tantalum pentachloride vaporizes and is condensed first; niobium oxychloride sublimes at higher temperatures.  The residue after sublimation and the fraction containing tantalum pentachloride if contaminated with niobium pentachloride, may be recycled to the process for re-chlorination. According to an example, briquettes were made of 1 part of carbon black to 4 parts of niobium/tantalum oxide mixture and chlorination was effected at 600 to 1000 DEG C. in a shaft furnace.  The chlorination products were rapidly separated and removed from residual gases and thereafter subjected to fractional vacuum sublimation.  A further example refers to columbite ore mixed with 20% of carbon and chlorinated at 700 DEG C.  The chlorination products were passed through two condensers one at 200 DEG  and the other at room temperature over 80% of the niobium condensed in the first condenser.  Specifications 507,124 and 644,454 are referred to.
