Title: Improved process of precipitating metals from solutions
IPC: C22B3/44
Filed: 1922-04-25
Abstract: 201,231. Marks, E. C. R., (Merrill Co.). April 25, 1922. Precipitating.-In the precipitation of precious and other metals from cyanide and other solutions, by chemical precipitants, interfering dissolved gases are removed from the solution by means other than heating the solution or by the action of the precipitant itself, for example by chemical or mechanical means. The chemical elimination may be effected by a. reducing agent such as sodium sulphide or hydrogen; the mechanical elimination may be effected by exhaustion; and the elimination may be effected prior to or during the precipitation. In the plant shown, solution to be treated is pumped from a tank 2 to a feed tank 3 from which it is drawn by a vacuum pump and caused to pass over baffle-plates 13 in a vessel 4 connected by a barometric tube 44 to a tank 14 fitted with a stand-pipe 16 and overflow 15. From the tank 14 the solution is pumped to a filter press 9, the precipitant, which may be zinc, being admitted from a hopper 6. The apparatus is so arranged that the pressures existing in the plant prevent the ingress of atmospheric air. In modified forms of plant, the tanks 2, 3 may be so arranged that the solution flows directly from one to the other without the intervention of a pump 7; a tank such as 14 may be dispensed with; the precipitant may be admitted into the vessel 4; or the pump 8 may pars the solution to zinc precipitation chambers instead of precipitant being previously added to the solution, the precipitation chambers being either exhausted or left open to the air, the hydrogen evolved serving in the latter case to prevent reabsorption of interfering gases.

Abstract: 1505207 Electrical connectors F R BONHOMME 23 March 1976 [11 April 1975] 11667/76 Heading H2E [Also in Division H1] A printed circuit board 1 engaging a multicontact connector of the kind described in Specification 1,480,721 has formed therein conductive tracks 8 of concave cross-section (Figs. 2, 3) wherein V-shaped elongate cavities 9 are machined in the surface of the insulant substrate and metallized to form a conductive layer 10 extended outside the contact area by flat surface conductors 11. The conductive tracks may have a channel cross-section with oblique or curved sides. The connector may comprise plural resilient contact members 2 grouped in pairs (Fig. 1) each formed of a circular wire with a rectilinear portion extending through a U-shaped insulating case 3 and a connecting board 4. Mortises 5 of the case engage tenons of slides 6 displaceable perpendicular to the plane of the figure by sliding strips 7 between a closed position of the upper part and an open position of the lower part of Fig. 1. Members 2 have an active region 2d between end 2c and loop 2b which in the closed position engage the opposed conductive track 8 or are disengaged from it in the open position during introduction or extraction. The conductive tracks and their cavities may extend to the edge of the board, and the depth depends on the thickness of board 1 and the diameter of the contact members. Also the width of each cavity enables the corresponding member to rest in the centre of the V, while the angle thereof enables the active region of the member to be centred by pressure on the board into the bottom of the V. Thus contact is made along two lines axial of the member in tangential contact with the conductive layer of the cavity. The contact members may be quadrangular. Specification 1,028,146 is also referred to.
