Title: Improvements in air blast electric circuit breakers
IPC: H01H33/867
Filed: 1955-02-10
Abstract: 764,647. Air-blast switches. ALLMANNA SVENSKA ELEKTRISKA AKTIEBOLAGET. Feb. 10, 1955 [Feb. 17, 1954], No. 3981/55. Class 38(5) In an air-blast switch having contacts 4, 5 arranged within a compressed air container 1, the opening of an outlet valve 17, 18 allows the compressed air in the container to move the contact 5 to the open position in which a valve member 6 carried by the contact blocks the outlet for the compressed air so that the airblast occurs only during the period of contact opening. The outlet 17 is opened by the valve element 18 when pressure is applied to a membrane 19, the element 18 in its opened position closing the outlet of a pipe 22. The air blast occurs through the tubular contact 5, openings 13 and the outlet 17 when the contact 5 is moved by the air pressure acting on it, its movement being braked by a piston 8 moving in a cylinder 9 connected through a throttle valve 10 to the container. When the member 6 abuts a seating 14, the blast ceases. To reclose the switch, the membrane 19 is relieved from pressure and a spring 23 moves the valve element 18 to the right to close the outlet 17 and open the pipe 22. This equalizes the pressure above and below the member 6 and a spring 12 recloses the contacts.

Title: Methods of making abrasive wheels
IPC: B24D18/00
Filed: 1936-02-14
Abstract: 451,641. Moulding grinding-wheels. NORTON GRINDING WHEEL CO., Ltd., Welwyn Garden City, Hertfordshire. Feb. 14, 1936, No. 4486. Convention date, Feb. 19, 1935. [Class 87 (ii)] A grinding-wheel is made by placing a preformed central support 26 of a thermosetting substance such as artificial resin in a mould 10 which may consist of an annular band surrounding press plates 12, 14 and a central arbor 28. The plates 12, 14 can be moved toward each other by press platens 16, 18 having passages 20 for receiving steam and cooling water. Round the support 26 an abrasive mixture 31 is packed comprising grains of diamond, boron carbide, silicon carbide, quartz or crystalline alumina &c. mixed with a thermo-plastic material such as artificial resin, rubber or shellac. Steam is admitted to the passages 20 and the heat transmitted to the mould is sufficient to soften the material of the support 26. Pressure is simultaneously applied to the plates 12, 14 which causes the material of the support 26 to flow radially and compress the abrasive mixture 31. The further application of heat and pressure renders the bonding material in the mixture 31 plastic and causes it to unite with the material of the support 26. The same method may be used in the manufacture of a cup wheel in which a mould comprising a ring 35, press plates 37, 38, and a central arbor 28 as shown in Fig. 3, encloses resinoid material 40 forming the wheel backing and the abrasive mixture 41. Pressure applied to the plates 37, 38 causes the resinoid backing 40 to flow and compress the abrasive mixture.

Filed: 1938-02-14
Abstract: 514,938. Electron multipliers. RADIOAKT.- GES. D. S. LOEWE. Feb. 14, 1938, No. 4542. Convention date, Feb. 17, 1937. [Class 39 (i)] The final stages of an electron multiplier, preferably used in combination .with a series of multiplying grids of the ordinary type, consist of semi-cylindrical grid, opposed to a solid, semicylinder of the same diameter and a rod co-axial with them, the collecting electrode being a cylindrical grid, the diameter of which is preferably the geometric mean of those of the rod and the outer electro 19, the object being to diminish capacity in the last stages. Electrons which may be obtained as shown from a photoelectric cathode 9 pass after multiplication at the grids 2 to the system according to the invention which is mounted within a screen 3 which may be at the same potential, as the cathode 9. The system consists of a semicylindrical multiplying grid 1 from which electrons are drawn by the positive potentials on the rod 5, grid 6, and plate 4. The potentials of these four electrodes are respectively 100, 200, 400 and 300 volts, but the grid 6 is of wide mesh and most of the electrons pass through to the secondary emitting surface 4, whence they are drawn back by the grid 6, through which they again pass to the rod 5. This emits further secondary electrons which are collected by the output electrode 6. The lead from the collecting grid 6 is brought out separately from those to the other electrodes and may be connected to an amplifying valve 11.

Title: Lithium carbonate production
Inventor: ARCHAMBAULT MAURICE
IPC: C22B26/12
Filed: 1960-02-09
Abstract: Lithium carbonate is produced by reacting calcined lithium bearing silicates hydrothermally with aqueous sodium carbonate (preferably 1 to 12 times the weight of the silicate) at 140 DEG  to 300 DEG C. in a pressure vessel.  The resulting slurry may be leached with an aqueous solution in the presence of enough carbon dioxide to saturate the solution.  This step is preferably effected by agitating the slurry at-10 DEG  to 40 DEG C., 150 p.s..i.g using 25 to 50 times the weight of the lithium oxide present in the lithium bearing charge of solution.  The remaining solids are removed from the solution and the lithium carbonate is precipitated by heating the solution at 60 DEG to 100 DEG C., or by beating, ultrasonic irradiation or vacuum treatment.  The lithium bearing silicates may be petalite, eucryptite or lepidolite or preferably spodumene, previously calcined at 680 DEG to 980 DEG C.  The process may be effected cyclically.  A slurry containing lithium carbonate and anhydrous sodium aluminosilicate jadeitelike in chemical composition (Na2O.Al2O3. 4SiO2) is produced if sodium carbonate is used in an amount of 3,5 to 7 times the weight of lithium oxide present, with water in an amount from 1 to 1,6 times the weight of the lithium bearing charge at 150 DEG  to 180 DEG C. for 35 t 50 minutes.  A slurry containing lithium carbonate and isometric sodium zeolite (Na2O.Al2O3. 4SiO2.xH2O) is produced if sodium carbonate is used in an amount from 3,5 to 7 times the weight of lithium oxide present, with water in an amount from 1,3 to 2,3 times the weight of the lithium bearing charge at 185 DEG  to 250 DEG C. for 10 to 60 minutes.  A slurry containing lithium carbonate anisometric p  sodium zeolite (Na2O. Al2O3.2SiO2.yH2O) is produced if sodium carbonate is used in an amount from 7 to 14 times the weight of lithium oxide present, with water in an amount from 1,3 to 2 times the weight of the lithium bearing charge at 140 DEG  to 175 DEG C. for 5 to 60 minutes.  A slurry containing lithium carbonate and sodium cancrinite (approximating to 3Na2O.4Al2O3.9SiO2.2Na2CO3. 3H2O) is produced if sodium carbonate is used in an amount 14 to 29 times the weight of lithium oxide, with water in an amount from 2,5 to 7 times the weight of the lithium bearing charge, at 185 DEG  to 200 DEG C. for 1 to 5 minutes.

Abstract: 809,792. Making rods or tubes from powdered material by extrusion. GENERAL ELECTRIC CO. Feb. 15, 1956 [Feb. 15, 1955], No. 4757/56. Class 87(2). Pulverulent material 10, Fig. 1, is fed down through central passage 9 in a rotating tube 8 into an. extrusion nozzle 1 and is forced through the nozzle, to emerge as a rod 22, by a contoured compacting member 3 secured to the base of the tube 8, Fig. 3, shows the contoured base of the member 3, which comprises three sectors 16, 20, 17. Section 16 is disposed adjacent a step 15, and into it opens a skewed feed passage 11 which forms a continuation of passage 9. Sector 20 is a plane surface extending horizontal ly. Sector 17 is inclined downwardly from line 19 to line 18 and is substantially helical, and forms the pressing face which forces material down through the nozzle. The tube 8 and member 3 are rotated by a worm gear drive W. The nozzle 1 may taper towards its outlet. The material may be ceramic raw material, or may be titanium sponge in which case the nozzle taper may be 0À04À0À08 inch per foot, and the titanium rod or tube that is made may be a consmnable electrode for a vacuum or inert gas atmosphere arc furnace, the nozzle 1 being formed integrally with the furnace enclosure or attached thereto by means of a hermetic seal. The nozzle entrance has a removable hardened bushing 25. Figs. 2 and 4 show a modified construction in which the nozzle comprises a tube 32 having slots 34 through which project fingers 36 which are rockable about their upper ends 37 and have outer cam surfaces 41 embraced by a ring 42. The ring is slidable up and down on the cam surfaces, to vary the extent to which the fingers project into the interior of the nozzle and hence the degree of restraint upon the material passing through the nozzle. The ring may be moved up or down by hand or by automatic means responsive to loading variations of an electric motor which turns the compacting member 3. Fig. 5 shows another construction, for making tubes, comprising a mandrel 54 having a screwthreaded exterior which forms a screw thread 66 on the interior of the extruded tube 64. The mandrel is hollow and accommodates an electric resistance heater 67 (or a cooling coil, Fig. 7, not shown). Gas or solid may be fed to the furnace (or into the tube) through a conduit conduit 56 extending through the tip of the mandrel. Fig. 8 shows a construction in which (a) the end of the compactor is bevelled at 72 to prevent leakage of material, and (b) the nozzle is slit at 75 and has means for opening or closing the slits, this means comprising a collar 77 the internal dimension of which varies according to its temperature, which may be adjusted by means of coolant passages 78 and heaters 79 : this adjustment may be automatic, being dependent on the loading variations of the electric motor used to drive the compactor. In another modification, Fig. 9 (not shown) the compactor is surrounded by a resilient split helical ring which prevents leakage of material.
