Abstract: 648,415. Endless-chain conveyers; delivering metal powder from hoppers. MOND NICKEL CO., Ltd., and COMLEY, M. A. March 25, 1948, No. 8818. [Class 78 (i)] [Also in Groups V and XXII] In a method of making a porous metal plate by powder metallurgy, the metal powder is compressed and sintered between two formers having surfaces which are roughened or corrugated so as to prevent the plate from contracting in directions parallel to its main surfaces. Rectangular moulds 1 with depending guide lugs 42 are moved over a flat horizontal track 2 by an endless-chain 4 passing over idle and driven pulleys 5, 6. The moulds are secured to the chain by links 3 and pass beneath a hopper 8 from which they are filled with metal powder, beneath levelling devices 11 and 12, beneath a stack of refractory cover-plates 13, each mould receiving one such cover, through a sintering furnace 14 and a cooling device 15. Powder falling from the track during the filling of the moulds is received by a hopper 25 leading to a bin 26. As the moulds pass round the pulley 6, the cover-plates fall on to an elevator belt 17 by which they are carried around a curved guide 19 to a conveyer 20 and thence back to the stack 13. A bank of electromagnets 21 retains the sintered plates in the moulds until they reach an inverted position over a collecting receptacle 22. The lower part of one wall of the hopper 8 is offset outwardly at 31 and on the inner face of the wall is a plate 32 formed with a rack 33 so that it may be raised or lowered by a pinion 34 to adjust the discharge opening 37 between the lower end of the plate and a wall 36 extending upwardly from the lower end of an inclined base 35. A porous plate extends across the hopper above the bottom, leaving an air space 39 into which air is admitted under low pressure from a pipe 40. The air passes through the porous plate and carries powder through the opening 37 in a uniform stream which is deflected downwards by the offset wall portion 31.

Title: Methacrylate polymers
Inventor: MILLS BRIAN
IPC: C08F20/12
Filed: 1957-03-20
Abstract: Esters of methacrylic acid and C1-C4 monohydric alcohols are polymerized by adding the ester to a compound having the formula RMgX, in which R may be an alkyl, cycloalkyl, aryl or p  aralkyl and X may be a chlorine or bromine atom, this compound being admixed, if desired, with a liquid which will dissolve the ester.  The methacrylic ester, which is preferably added gradually to the reaction mixture, may be used in conjunction with other monomers such as methyl isopropenyl ketone, methacrylonitrile and glycol dimethacrylate.  The polymers produced are crystalline or crystallizable; in the case of crystalline polymers their crystallinity may be improved by an annealing process which is preferably conducted at a temperature between 15 DEG  and 25 DEG  C. below the melting-point of the polymer; polymers which have been melted may be crystallized either (a) by treating a sample of the polymer having fresh surfaces with a liquid which swells the polymer, e.g. diethyl or diisopropyl ether, which treatment may be followed by annealing; or (b) by extruding the polymer at a temperature at which it is a rubbery melt, stretching it rapidly, chilling it and, while preventing its shrinkage, holding it at a temperature between its rubber-glass transistion point and its melting-point.  The polymers of methyl methacrylate thus produced have an infra-red absorption band at 955 cm.-1  The polymers may be used as reinforcing fillers for butadiene/acrylonitrile rubber, and vulcanizable compositions are disclosed which comprise a butadiene/acrylonitrile rubber, a polymethyl methacrylate produced as described above, bis - (2 - hydroxy - 3 - alpha - methylcyclohexyl - 5 - methyl phenyl) methane and conventional vulcanizing recipe ingredients.
