Title: Improvements in or relating to holders for rolls of paper and packets of sheets of paper
IPC: A47K10/32
Filed: 1936-05-22
Abstract: 475,797. Holders for packets or rolls of toilet &c. paper. SCHIFF, K. L. May 22, 1936, No. 14462. Convention date, May 27, 1935. [Class 18] In a holder for two rolls of toilet &c. paper, only one roll is freely accessible at a time, and when the paper on this roll is exhausted, movement of the support for the rolls and/or a cover for one of them renders the " out-ofuse " roll freely accessible and the " in-use " roll, substantially inaccessible. The invention is also applicable to a holder for two packets of sheets of paper. In one embodiment, two rolls 11, 12, Fig. 1, are suspended from a baseboard on the usual pivoted bow-shaped frames, and a curved shield 16 slidable along a wire 15 on the baseboard, can be adjusted to cover either roll and prevent access thereto. The rolls may be mounted between fixed cheeks 32, Fig. 3, on a board 34 which is pivoted on a stud 35 to the baseboard, the top roll being normally covered by a hinged hood 37. To use the top roll, the hood 37 is swung upwards, the board 34 rotated until the position of the two rolls is reversed, and the hood lowered again. In a modification the stud 35 passes through a vertical slot so that the board 34 will always rest in a stable position. In a further embodiment, the roll spindles extend between the side walls of a member 4, Fig. 6, which is pivoted at 44 to the side walls of a hood 43 hinged to the baseboard. Paper is drawn from the bottom roll, and to reverse the position of the rolls, the hood and member 40 are swung up as shown by the dotted lines and the member 40 rotated on the pivots 44. A core for a roll comprises a millboard tube 50, Fig. 7, and end caps 51, 52 which are supported between springy arms 58 by the engagement of the caps by an annular member 54 and a stud 67 respectively projecting from the arms. The tube and end caps may be substituted by a solid core. A holder for packets of interleaved sheets of paper is provided with delivery slots 22, Fig. 2, and either slot can be closed by a slide 25 whose inturned edges run in grooves 24. The slide is provided with a handle, and the case can be swung away from the baseboard when a new packet is to be inserted. The compartments of the holder may be arranged side by side with the delivery slots underneath. Inspection openings may be provided in the walls of the various holders. The Specification as open to inspection under Sect. 91, comprises also a modification wherein the hood 43, Fig. 6, is substituted by links or a bow pivoted to the baseboard and to the member 40. In a further modification, a frame 40<1>, Fig. 7 (Cancelled), carrying the rolls is pivoted in slots 48 in arms 43a on a baseboard 46<1>. To reverse the positions of the rolls, the frame is drawn up the slots 48, rotated, and then allowed to fall back. The slots can be formed in the frame and the pivots provided in the arms 43a. This subject-matter does not appear in the Specification as accepted.

Title: Improvements in the treatment of lead-zinc sulphide ores, mattes and the like
IPC: C22B19/20
Filed: 1923-06-02
Abstract: Lead-zinc ores, concentrates, &c., particularly when lead is predominant, are chlorinated at 600-700 DEG  C. with chlorine or sulphur chloride in known manner, and the sulphur and zinc chloride volatilized are received in a condenser containing a strong solution of zinc chloride, the sulphur forming a layer upon the solution, while the zinc chloride vapour condenses and dissolves in the solution.  The mixture of chlorides is leached with water or zinc chloride solution to dissolve out zinc and iron chlorides and the solution thus obtained may be fed to the condenser.  Strong solution is withdrawn from the condenser from time to time and may be mixed with zinc ores, concentrates, &c. dried, and chlorinated with chlorine or sulphur chloride to produce a chloride melt which is treated with zinc to precipitate iron lead and silver &c., while the purified chloride is electrolyzed for zinc and chlorine.  The purified lead chloride is fused and electrolyzed, preferably in the apparatus described in Specifications 198,024 and 208,649, [both in Class 39 (iii), Heating by electricity].  The electrolysis may be effected in one operation or fractionally, in which case the silver and some lead may be first deposited, and then pure lead. Preferably, the process after the chlorination is effected at 400-450 DEG  C.  The presence of manganese during the electrolysis is advantageous, and a manganese compound may be added if manganese is not present in sufficient quantity.

Title: Improvements relating to the treatment of nickel-copper solutions to remove iron present therein
IPC: C22B3/44
Filed: 1931-05-21
Abstract: A process for the removal of iron from nickel salt solutions by hydrolysis in which the solution is first neutralized and then blown with air is characterized in that neutralization is effected by a strongly reactive metallic nickel product obtained by gas reduction of nickel compounds at low temperatures, preferably from 350-450 DEG C.  Hydrogen or water gas are specified for the reduction.  The nickel serves also to cement copper present.  The process, which is effected below 60 DEG  C., is of general application, but a special application is described, wherein nickel-copper matte is ground, roasted to remove sulphur and leached with acid for the partial removal of copper.  Part of the leached residue is reduced under the specified conditions to obtain a nickeliferous metallic powder.  The remainder is converted to metal and cast into anodes for use in an electrolytic cell, which is divided into cathode and anode compartments by a filter diaphragm, through which the electrolyte at about 50 DEG  C. flows from the former to the latter.  The solution escaping from the anode compartment is purified by the present process employing the nickeliferous powder obtained as above, and is returned to the cathode compartment.  The exhausted nickeliferous material is mixed with the ground matte and re-used.  The metals may be present as sulphate or chloride, and the electrolyte preferably contains a buffer, such as boric acid.  Specification 185,859, [Class 1 (iii), Oxides &c., Metallic], is referred to.ALSO:A strongly reactive metallic nickel product, obtained by gas reduction, for example with hydrogen or water gas, of nickel compounds at low temperatures, preferably from 350 to 450 DEG  C., is used to neutralize the acidity and to cement the copper present in nickel salt solutions below 60 DEG  C. from which iron is subsequently removed by oxidation with air.

Abstract: 1311525 Inspecting optical elements by holography CANON K K 31 March 1970 [31 March 1969 4 March 1970] 15138/70 Heading G2J A method for checking the accuracy of an optical element, for example a lens 14, comprises splitting a coherent wave into a test wave 15, whichis passed through the element; and a reference wave 11, directing the waves 11 and 15 on to an artificially prepared holographic test plate A and selecting waves radiated from the test plate to obtain an interference pattern. The test plate A is produced with an interference pattern such that if the element 14 has the required parameters, then the test wave emerging from the plate A resembles the reference wave so that if mirror 13 is tilted parallel equally-spaced fringes are obtained in the plane 18; if the element 14 deviates slightly from requirements the fringes are distorted. The waves emerging from the plate A are condensed by a lens 16 and the required diffraction orders selected by means of an aperture 17. Alternatively, Fig. 3 (not shown) the lens 16 may be omitted and the holographic test plate be a Fresnel zone plate (A'), so that the different orders of diffraction are concentrated at different distances from the test plate, Fig. 4 (not shown). The use of an artificially prepared holographic plate obviates the preparation of a master optical element and permits the preparation of complicated, e.g. non-spherical, surfaces.
