Title: New method of preparing manganese salts from pyrolusite ore
Inventor: NAIR VATTAVILA SIVASANKARA KRI
IPC: C01G45/10
Filed: 1965-09-07
Abstract: Manganese values are obtained as soluble manganese salts from MnO2 ores containing much iron by treating the ore with an aqueous ferrous salt solution to reduce the manganese to manganous, e.g. by boiling for 4-6 hours under reflux, preferably on a sand bath or heating mantle, after which the solution is preferably allowed to settle and the clear liquor is decanted, siphoned or filtered off.  Any unreacted ferrous iron is then oxidized to ferric by (a) bubbling air or oxygen through the hot solution, (b) adding a small amount of an oxidizing agent, e.g. H2O2, HNO3 or by (c) anodic oxidation, and precipitated as Fe(OH)3 or Fe2O3.nH2O by raising the pH to between 5 and 6.3, but preferably 5.3-5.5, with a base, e.g. NH3, KOH, NaOH or a NH3/NH4Cl mixture. A small amount of hydrazine hydrate may be added before the base, particularly if NH3 is used, to quicken the settling.  Waste pickle liquor may be used as the ferrous solution, the free acid therein being preferably removed before use by iron metal e.g. scrap-iron, or by manganous oxide, e.g. as obtained by a reduction roast of MnO2.  If desired, the remaining solution after precipitation may then be evaporated to obtain the manganese salt as a solid double salt with the salt of the base which was used for raising the pH of the solution.

Title: Methods and apparatus for obtaining traffic data

Abstract: 991, 930. Indicating road occupancy. GENERAL SIGNAL CORPORATION. Nov. 10, 1961, [Dec. 27, 1960], No. 40317/61. Heading G4Q. A method of measuring a parameter relating to flow of objects along a path comprises detecting each object as it passes a detection point and generating a signal and modifying the signal as a function of time to produce a second signal having a characteristic proportional to the parameter to be measured. As described, vehicle monitoring equipment comprises an ultra-sonic detection system the received output from which is fed to gated circuits 17, 18, Fig. 2, which are opened at the time when a reflected signal from a vehicle, or from the road, is due respectively. The outputs from these circuits are fed to switch a bi-stable circuit which causes relay VR to operate when a vehicle is present, and to release when no vehicle is present in the detection zone. Traffic density. Fig. 3. Relay VR operates contact 23 to charge the CR network 26-31 during the presence of a vehicle, and allow it to discharge during the absence of a vehicle, so that the signal at the output of the network is proportional to traffic density. In the event of a complete stoppage of traffic relay SR operates to connect a fixed charging potential to the network, thus giving an artificial density figure. Stoppage circuit. The stoppage relay SR is operated by a timing circuit 80, Fig. 6, which is energized over contacts 81, 82 only when the average speed is low and the vehicle density is high. Under these conditions, timer 80 starts to time out but is reset every time relay VR changes over, so that it only reaches the end of its timing period if the traffic comes to a standstill. Relay SR then operates to give an artificial condition signal. The output from the CR network 26-31 of Fig. 3 is fed to a cathode follower circuit to give an indication of the parameter measured on meter 40, and also to operate relays R1, R2, R3 at predetermined values of the parameter. Separate detectors may be employed on a number of lanes, and their outputs summed to give an average figure at the grid of cathode follower 46, the output circuit of which is provided with a similar meter 53 and relay circuits ST. Traffic volume may also be measured, Fig. 4 (not shown) in a similar way to density, by providing a constant charge for the CR network with each vehicle detected. Flow density, Fig. 5 (not shown). The signal fed to the CR network is derived from a Doppler speed detection system. Specification 931,125 is referred to.

The shank 4 of the draw gear, Fig. 14, extends longitudinally through a striker casting 6 secured to a centre sill by its wall 74, Figs. 1, 7, and is supported at its forward end on a carrier 12 between upstanding ears 38, 39 thereon. The carrier normally slides transversely to centralise the shank, but this action can be rendered inoperative so that the draw gear may be easily angled to one side as for coupling up on a curved track. The carrier 12, Figs. 3, 4 is mounted between the side frames of cage 10, Figs. 5, 6, and is normally centralised therein by a resilient cushion or spring 13 positioned by lugs 21, 22 on the carrier and cage respectively. The cage has lugs 42, 43 with a slot 61 therebetween, which lugs engage and slide in a slot 45 in a plate 36 forming the removable bottom of an outer casing 8, Fig. 2. The casing 8 which is permitted vertical movement only within the striker casting 6 is provided with downwardly opening sockets 66, 67 accommodating the tops of springs 71, 72, and the springs which support the weight of the draw gear are located at their bottom ends by plates 81. A lever 57, pivoted on a bolt 59 between downwardly extending cheeks on the bottom of the plate 36, has a detent 60 which in normal draft operation engages in the slot 61, so that the draft gear and carrier 12 may only move transversely of the casting 6 by compressing the spring 13. When, however, the lever 57 is pivoted to remove the detent 60 from the slot 61, the cage 10 and carrier 12 with the gear mounted thereon may be slid easily to one side out of the centralised position.
