Abstract: 509,902. Making paper &c. containers. WARE, H. M., and WARE & CO., Ltd., H. M. Jan. 24, 1938, No. 2252. [Class 18] [Also in Group XVI] Paper, wood-pulp and like containers for milk, ice-cream &c. are treated prior to waxing so as to bend in the upper sides a, b, Fig. 9, of the container and to produced W-shaped fold lines c, d in the other upper sides so as to facilitate the closing and sealing operations after the container is waxed. The fold lines &c. are produced during the manufacture of the container by pressing a creased blank around a mandrel 1, Fig. 1, by means of a forming and folding unit comprising hinged parts 12, 13, 14, 15, 16 of which the part 12 is hinged to a base 10. A bottom 35 for the container is placed over the mandrel 1, and each of the parts 12, 16 is formed with a pivoted upper flap 30 for bending over a flange of the blank and securing it to the bottom 35. The lower part of the mandrel 1 is shaped to permit of the formation of the W-shaped lines c, d, Fig. 9, by means of forming members 20, 23 attached to the hinged parts 13, 14 which co-operate with projecting parts 7, 8 attached to the mandrel. When the parts 13 ... 16 are closed around the mandrel they are held by a catch to permit the glued edges to set, and the final shaping is effected by operating knobs 28, Fig. 7, attached to pivoted parts 23, 24, 25 which bend in the sides a, b of the container. The parts 23, 24, 25 are carried by the hinged parts 12, 15, 16.

Title: Improvements in recovery of nickel with or without cobalt from hydrometallurgical solutions
IPC: C22B23/00
Filed: 1961-01-20
Abstract: Nickel and cobalt sulphides are precipitated from nickeliferous sulphate solutions by the action of metallic iron and elemental sulphur coated with an alkali metal sulphide.  The reaction mixture may be agitated to keep the sulphur and sulphur products in suspension while the iron particles remain at or near to the bottom of the reaction tank.  Preferably ferric ions present in the solution are reduced to ferrous ions, prior to the precipitation step, by treatment of the solution with pyrrhotite concentrate at a temperature of 65 DEG  to 75 DEG C.  The coating of the sulphur particles may be achieved by mixing in an agitated tank sulphur flour, an equivalent quantity of water, a wetting agent and sodium sulphide in an amount of 5% of the sulphur.  Solutions containing nickel, cobalt, copper, iron and sodium may be treated to precipitate the nickel and cobalt.  Specificatio 769,267 is referred to.

Title: Television signal combining amplifier
IPC: H04N5/067
Filed: 1945-01-31
Abstract: 596,394. Television transmitters ; valve modulating circuits. FARNSWORTH TELEVISION & RADIO CORPORATION. Jan. 31, 1945, No. 2493. Convention date, Feb. 5, 1944. [Classes 40 (iii) and 40 (v)] In a television mixing circuit comprising a multi-electrode valve, means are provided for permitting the flow of current in the control grid circuit, to which are 'applied the" video signals, while the blanking signals are applied to the screen grid so to modify the control grid current that a composite television signal is formed at the control grid. In the arrangement shown, horizontal blanking signals from a source 17 and vertical blanking signals from a source 13 are combined in the pentode valve 12, the output from which is taken to the screen grid of a tetrode 11. Video signals from a source 27 are taken to the control grid which is so biassed that grid current normally flows. The flow of grid current causes a reduction in the potential at the control grid ; however when a positive blanking signal is applied to the screen grid, current tends to flow past the control grid to the anode, thereby reducing the grid current and increasing the grid potential. Moreover, the video signal is suppressed during the blanking intervals, so that signals of the form shown in Fig. 3 are produced at the output 35. In a further embodiment, Fig. 2 (not shown), a radio frequency source is inserted into the control grid circuit so that the signal of Fig. 3 is modulated on to a carrier wave. The output is taken from the anode of the tetrode, an anode resistor being provided for this purpose.

Patent GB-1076894-A (GB)
Title: Method of strengthening glassware
IPC: C03C21/00
Filed: 1965-01-22
Abstract: To strengthen glassware made from silicate glass containing at least one alkali-metal ion of relatively small ionic diameter, two different ions of different, larger, ionic diameter are introduced to replace a part of the alkali-metal ions on a surface layer, the smaller of the replacement ions being introduced to a greater depth. Particularly for a double alkali-metal glass such as Li-Na-silicate glass, the ion exchanges may be effected concurrently, as by an equal mixture of NaNO3 and KNO3, the smaller ion penetrating more deeply into the glass: otherwise the strengthening is performed in two or three steps, as a Li-glass immersed first in an Na salt, then in a K salt only or with an intermediate step of immersion in a mixture of the two salts.  A number of examples of different baths and treatment times and temperatures are given.
