Title: Improvements in production of titanium
IPC: C25C3/28
Filed: 1959-02-09
Abstract: 865,266. Electrodeposition of titanium. NEW JERSEY ZINC CO. Feb. 9, 1959 [March 19, 1958], No. 4439/59. Drawings to Specification. Class 41. In the electrolysis of a fused halide salt bath containing trichloride and titanium dichloride, wherein titanium tetrachloride is continuously introduced into and assimilated by the bath and metallic titanium is deposited on a cathode immersed in the bath, the titanium tetrachloride being introduced into the portion of the bath in contact with the surface of the cathode distal with respect to the anode, and the portion of the bath between the anode and the proximate surface of the cathode being substantially completely depleted of titanium ions so that the metallic titanium is deposited primarily on the aforesaid distal surface of the cathode, the anode and the deposition cathode being in direct fluid communication with one another through the medium of the bath, circulation of the bath in contact with the distal surface of the deposition cathode is effected so as to maintain substantially uniform concentrations of the titanium trichloride and titanium dichloride in all portions of the bath which are adjacent to said distal surface and an auxiliary cathode also in contact with the bath, the auxiliary cathode being in direct fluid communication with the deposition cathode through the medium of the bath therebetween, and the cell atmosphere above the deposition cathode being in direct communication with the cell atmosphere of the auxiliary cathode; the electrolysing current is distributed between the deposition and auxiliary cathodes so as to maintain substantially different current densities thereat, the current density at the auxiliary cathode being such as to effect electrolytic reduction of titanium trichloride to titanium dichloride but insufficient to develop such polarization as to effect significant electrolytic reduction of titanium dichloride to metallic titanium. The molten salt bath may comprise one or more of the halides of the alkali metals and alkaline earth metals, i.e. the chlorides, bromides, iodides and fluorides of, for example, sodium, potassium, lithium, calcium, magnesium, barium and strontium. A preferred bath comprises a eutectic mixture of 5 mol. per cent sodium chloride, 40 mol. per cent potassium chloride and 55 mol. per cent lithium chloride. In examples, the circulation of the electrolyte is effected by feeding titanium tetrachloride below the melt surface in a carrier gas such as argon. Circulation may also be brought about by the use of a mechanical stirrer and by the effect of thermal convection currents. The distribution of the current between the deposition cathode and the auxiliary cathode is preferably such that the average titanium valency in the portion of the bath adjacent to the deposition and auxiliary cathodes is between 2.2 and 2.5, but the current is so regulated that less than 15% of the total metallic titanium is deposited on the auxiliary cathodes. Specification 777,892 is referred to.

Title: Separation of gas mixtures
IPC: C01B3/56
Filed: 1977-02-03
Abstract: 1536995 Adsorption process LINDE AG 3 Feb 1977 [4 Feb 1976] 04450/77 Heading B1L Two gases (e.g. CO and H) are separated by passing the mixture at elevated pressure (e.g. 20 bars) through two beds of adsorbent in series which preferentially adsorb one gas (CO) to deliver pure H from the second bed (stage I in Fig. 4), until the adsorption front reaches the upstream end of the second bed 2. The pressure is then reduced (stage II) while pure H is still withdrawn from bed 2, and at the lower pressure a second gas or gas mixture, whose partial pressure in CO exceeds that of the mixture to be separated, is fed to first bed 1, but this flow is stopped before any CO penetrates bed 2. The two beds are disconnected from each other (stage III), bed 1 being evacuated by pump 4 in the reverse direction to provide a flow of pure CO and bed 2 being reverse-flow flushed with H from stage II. The beds are reconnected (stage IV) and repressurised with H from stages II and possibly III, optionally in the reverse direction of flow. As shown some of the CO from stage III may be used as the second gas (mixture) in stage II. An optional stage I' may be included wherein a third gas mixture is fed through the beds, this mixture originating from bed 2 in stage III and having a greater partial pressure of CO than the mixture to be separated. Fig. 4 shows five two-bed systems operating in parallel, so that each system performs the sequence of stages, one stage out of phase with the next (Fig. 5 not shown). Each stage may last 5 minutes. The adsorbent may be zeolite, active carbon, silica gel, molecular filtration carbon. As described the process is applied to separating natural gas, from which water vapour and CO 2  have been first removed by conventional means. A small CH 4  fraction can be partly separated in stage II, wherein one component (H) emerges from bed 2 during pressure reduction while the CH 4  is retained by the bed until the second gas is fed into the beds.

Abstract: 715,404. Oscillating machines. ADAMS, ENGINEERING, Inc., L. S. Feb. 21, 1952 [Feb. 28, 1951], No. 4581/52. Class 35 [Also in Group VIII] A torsional oscillation is imparted to a roller 1 in addition to its continuous rotation, by means of A.C. electromagnets 20. The roller 1 is secured to a tube 5 which is mounted in a bearing 8 permitting angular movement corresponding to the torsional oscillation, the tube also carrying a rigid flange 7 on which the armatures 34 of the electromagnets are mounted. A torsion shaft 9 is secured to the end of the tube and is supported on a bearing 16. A pair of heavy wheels 11, 17 are secured to the shaft 9 by radial bolts 13 and a split ring collar 14, and an additional heavy plate 10 secured by bolts 12 to the wheel 11 carries the coil parts 20 of the electromagnets. The electromagnet pole-faces are set at about 20 degrees. Since the combined mass of the roller and armature assembly is small compared with that of the heavy wheels 11, 17 most of the movement is in the roller and little is transmitted to the drive. This may be by means of a belt 33 situated at a nodal point along the shaft length. The effective length of the torsion shaft, and therefore the natural resonant frequency of the system is adjusted by varying the thickness of a spacing ring 15.

Filed: 1961-02-10
Abstract: 898,862. Television. NIPPON ELECTRIC CO. Ltd. Feb. 10, 1961 [Feb. 26, 1960], No. 5090/61. Class 40(3). Relates to magnetic tape apparatus for the recording and reproduction of video signals of the kind employing a plurality of heads circumferentially staggered around a cylindrical drum which is rotated so as to bring the heads into use in recurrent succession. In such apparatus the tape exhibits expansion and contraction between recording and reproduction which tends to disturb frame synchronization and is compensated during reproduction by adjusting the closeness of spacing between the heads and tape, e.g. by varying the position of tape guides with respect to the head drum. In accordance with the invention, the adjustment is facilitated by arranging that the periods of operation by successive heads overlap partially, the interval of overlap including at least part of a frame synchronizing signal. In reproduction the signals from successive heads during the overlap period take the form shown at A and B or A and C where, due to tape distortion, the second signal is respectively advanced or retarded with respect to the first. The signals are combined to produce a resultant as at D or E and this is clipped to produce a signal as at F or G. In the final signal the pulses are wider than those in a normal signal, e.g. signal A, correct adjustment of the tape to head spacing being achieved when the pulse width is a minimum. In one way, of carrying out the invention, the combined signal during the overlap interval is separated and displayed on a cathode-ray tube as an oscillogram to permit manual adjustment. In another way, the pulses are integrated to produce a voltage which is displayed on a meter or employed for automatic adjustment by a servomechanism.
