Abstract: <PICT:0966619/C1/1> A graphite pin for electrically coupling an external power supply to an electrically-conducting member having a non-threaded socket adapted to receive the pin under compression, has a main body portion adapted for coupling to the external power supply and an unthreaded engaging portion having means therein for making the engaging portion more pressure-compliant these means extend paraxiially from the face of the engaging portion toward the main body portion and terminate within the pin the periphery of the engaging portion being cloven by such means in not more then one region. The engaging portion of the pin may be cylindrical, flared into and integral with the main body portion of the pin, and chamfered at the peripheral edge of its face. The joints described have low and uniform electrical resistance they may be used in electrolytic cells, where the connection may be between the pin and an anode. An anode may contain a plurality of sockets for use with the corresponding number of pins. In Fig. 2, the increased pressure compliancy results from the cutting of one or more kerfs 3 into the engaging portion of the pin 1 extending paraxially from the bottom face of this portion towards or into the main body portion of the pin. The kerf or kerfs may be annular, or three separated or joined cuts in triangular formation, or in the form of an Archimedean spiral, or a coaxial hole.ALSO:<PICT:0966619/C6-C7/1> In an electrolytic cell, the anode, which may be of metal or graphite, has one or more non-threaded sockets each adapted to receive under compression a graphite pin for electrically coupling an external power supply to the anode, which pin has a main body portion 1, Fig. 2, adapted for coupling to the external power supply and an unthreaded engaging portion having means therein for making the engaging portion more pressure-compliant these means extend paraxially from the face of the engaging portion toward the main body portion and terminate within the pin the periphery of the engaging portion being cloven by such means in not more than one region.

Title: Machine for rotating and cutting lengths of clay for the production of bricks
IPC: B28B11/14
Filed: 1967-09-30
Abstract: Apparatus for cutting lengths of clay, preferably from an extruder comprises a device which rotates the clay lengths through 90 degrees about a vertical axis and passes the rotated lengths through a multiple cutter and on to a series of rollers provided with spacers. Billets of clay are fed on to driven rollers 1, actuate trip 4 and pass on to partially grooved rollers 5 situated over frame 7. Frame 7 carrying the clay is lifted clear of the rollers, rotates through 90 degrees to the position shown dotted, and is lowered back to below the level of rollers 5. The clay then passes on to the base of the cutting device and is cut by inclined wires 36 moving vertically through the clay. The bricks formed are pushed from the cutter by bar 45 on to rollers 46 separated by belts. The belts are mounted on carriages movable perpendicular to the direction of motion of the clay, and are raised and lowered automatically and relative motion of the raised belts, carriages and rollers 46 separates the bricks laterally as they move along the rollers 46.

Filed: 1968-08-16
Abstract: A process for the production of a metal replica of a fibrous material comprises so impregnating a natural cellulosic fibrous material with a solution of one or more thermally decomposable metal salts that the solution enters the fibres, drying the impregnated material, and by a single heating in a reducing atmosphere destroying the cellulosic material, decomposing the salt or salts to metal and sintering the resultant metal to produce a coherent metal body having a porosity corresponding to the pores within the fibres as well as to the gaps between them in the starting material. The cellulosic fibrous material may be cotton in sheet form, e.g. woven or knitted cotton or cotton wool, cotton or sisal thread, jute sacking, blotting paper or paper pulp. The metal may be Fe, Co, Ni, Cu, or alloys thereof, or W, Mo, Ag, Au or a platinum group metal, but Ni is preferred and NiCl 2 is the preferred impregnating salt. The heating step is carried out at a temperature of at least 900 C. in which case the heating time does not exceed 60 minutes, but heating at more than 1000 C. for not more than 30 minutes is preferred, the heating in each case being carried out in a reducing atmosphere such as cracked ammonia. A metal plaque may be formed from porous sheets made by the above process, by bonding said sheets by compacting and/or sintering and the plaque may be impregnated to form an alkaline battery plate, e. g. a bonded stack of Ni plates may be impregnated with NI(OH) 2 by conventional methods.

Patent ES-428374-A1 (ES)
Title: Internal combustion engine
IPC: F02B1/04
Filed: 1974-07-17
Abstract: An internal-combustion spark-ignition V-8 piston engine has a main exhaust gas reaction chamber positioned between the two banks of cylinders. Each cylinder has a main combustion chamber and an auxiliary combustion chamber connected by a torch nozzle restriction. Valved intake passages supply lean mixture to the main combustion chambers and rich mixture to the auxiliary combustion chambers. A spark plug is associated with each auxiliary combustion chamber. Valved exhaust passages supply hot exhaust gases to auxiliary exhaust gas reaction chambers, each of which projects through an insulated wall of the main exhaust gas reaction chamber, and discharges into it. Each of the auxiliary reaction chambers is substantially larger in cross-section than each exhaust passage and each is substantially smaller in volume than the main reaction chamber and helps to minimize unwanted pollutants such as unburned nydrocarbons and carbon monoxide in the exhaust gases by maintaining the exhaust gases at relatively high temperature and for relatively long time periods before discharge into the atmosphere, and over a wide range of engine speeds and loads. A separate air pump is not required.
