Abstract: 130,709. Mond, R., and Heberlein, C. May 6, 1918. Drawings to Specification. Fungicides.-Fungicides for horticultural and like purposes or for destroying fungi in water reservoirs consist of copper sulphate together with about 93 per cent of the chemical equivalent quantity of an alkali carbonate or bicarbonate. It is stated that, owing to the formation of basic compounds, no free copper sulphate is left in solution, and that the maximum proportion of the colloidal compound produced is in the form of hydrosol. Preferred proportions are 4 lb. copper sulphate crystals to 4.25 lb. soda crystals. Solutions may be prepared for immediate use or the mixture may be put up in the dry form to be mixed with water for use. Dry mixtures of copper sulphate crystals with sodium bicarbonate alone or with a mixture of carbonate (crystals or anhydrous) and bicarbonate are stated not to interact on storing. Lime may be added to the mixtures as a substitute for part of the alkali carbonate or an inert substance may be added. A protective colloid such as glue may also be added. Mixtures containing various proportions of alkali carbonate greater than the chemical equivalents are also referred to.

Title: Improvements in or relating to toll systems for highways
Inventor: GRANT GARDNER LEWIS
IPC: G07F17/14
Filed: 1961-03-06
Abstract: 906,783. Signalling for road traffic purposes. UNIVERSAL CONTROLS Inc. March 6, 1961, No. 8055/61. Class 118. [Also in Group XIX] An automatic toll collecting system for highways designed to receive and register a toll consisting of a single coin or a mixture of coins, comprises powerdriven means for identifying and adding the coins deposited in payment of a toll and an electrical network operative if the value of the deposit equals or exceeds the prescribed toll, to produce a fare-paid signal. A vehicle entering the toll station is confronted with a STOP signal at an indicator 130. The toll to be paid is indicated on a board 120 and coins tossed into a collecting hopper 122 are identified according to their diameters, as described in Specifications 829,714 and 833,102. Electrical pulses, produced on recognition of a coin of a particular denomination, energize a relay circuit (Fig. 3, not shown) by which the coins are added and, when the required toll has been paid, a relay 52, Fig. 5, is energized, which, in turn, energizes a group of relays 60, 61, 62 by which two successive fare paid signals may be stored. Both of the relays 60, 62 may be locked by circuits containing the normally closed switches 43 (11, 12), 73 (21, 22). Whenever relay 62 is energized a relay 72, Fig. 4, of a fare cancellation chain, is actuated and completes a circuit through B3 to change the indicator from STOP to GO. The signal is returned to STOP when pulses, originating from a treadle 132 as the vehicle leaves the station and passed via a relay 54 (Fig. 3, not shown), to an axle counting chain, Fig. 4, energize a relay 43 as each second axle passes the treadle. This relay 43 opens momentarily switch 43 (11, 12) deenergizing relay 62 and hence 72. The number of axles which have passed is compared with the number for which a toll has been paid. If these agree but for some reason the signal remains at " GO," a timing relay 71, energized by operation of relay 72, acts through a relay 73 to release relay 62 by means of the switch 73 (21, 22). If they disagree, relay 54 will energize an alarm relay circuit (Fig. 3, not shown), which also includes a counting chain so that when a second consecutive violation signal is received a scavenger door is opened and allows faulty coins &c. to pass into a vault. Further lights 114, 116 or barriers, controlled from a central administrative building, may be used to indicate which lanes of the toll station are to be used, and the administrative building may also receive information on the number of vehicles using the highway.

Abstract: 1,244,606. Treatment of vanadium-containing Slags. INTERNATIONAL CARBON CORP. 27 Aug., 1968 [30 Aug., 1967; 19 Feb., 1968], Nos. 39701/67 and 8056/68. Heading C1A. Vanadium slags are made more susceptible to leaching in a process which comprises preheating the ground slag under inert conditions, and contacting the preheated slag with oxygen, the temperature of the slag when it is initially contacted with oxygen being at least 600‹ C., and such that the slag reacts with oxygen in a strongly exothermic manner, the maximum temperature reached by the slag whilst it is in contact with the oxygen being within the range 680-1050‹ C. The slag may be preheated in an atmosphere inert to the slag, e.g. of nitrogen, or whilst confined within a region filled with slag, e.g. a conduit leading to the zone where the slag is contacted with oxygen. The preheating may be affected by radiant heaters, or by fluidizing the ground slag with heated, inert gas. The preheated slag may be contacted with pure oxygen, with oxygen mixed with an inert gas, with oxygen-enriched air, or with air. Alkali metal salts, e.g. NaCl, or NaCl/KCl mixture, an NaCl/Na 2 S0 4  mixture or Na 2 CO 3 , may be added to the slag prior to its contact with oxygen. The slag may be contacted with oxygen on a rotary hearth or a moving belt or grate as a static bed, and is then, preferably, quenched. The solution obtained after quenching and/or leaching may be converted by known methods to vanadium pentoxide.
