Title: Clay products and fractionation treatment of clay
Inventor: ROWLAND BEN WRIGHT
IPC: C04B33/13
Filed: 1952-02-25
Abstract: Clay, containing two or more components each susceptible of deflocculation, is fractionized by establishing an aqueous suspension of the clay in a condition wherein the several components are all deflocculated, adjusting the condition of the suspension by the addition of a selective flocculating agent so as to effect flocculation of at least one but not all the components, precipitating the flocculated portions and separating the precipitate and supernatent suspension.  The selective flocculating agent may be a hydrophilic colloidal material, e.g. a poly-aliphatichydroxy polymer or a carbohydrate polymer or a water-suspensible derivative thereof. Manno-gelactan is preferably employed: other agents include glucomannan hydroxyethyl cellulose, extract of Jack-in-the-pulpit bulb and green seeds, extract of calla lily bulb, extract of iris bulb and water-dispersable polymers of urea-formaldehyde and styrene-malic acid.  The dispersing agent may be sodium hexametaphospate, tetra-sodium pyrophosphate or sodium silicate. Separation may be accelerated by the addition of a watersoluble inorganic salt, e.g. sodium sulphate or sodium chloride.  The solution should have a pH of 6 to 8.  Specification 748,213 is referred to.ALSO:Clay, containing two or more components each susceptible of deflocculation, is fractionated by establishing an aqueous suspension of the clay in a condition wherein the several components are all deflocculated, adjusting the condition of the suspension by the addition of a selective flocculating agent so as to effect flocculation of at least one but not all the components, precipitating the flocculated portions and separating the precipitate and the supernatant suspension.

As shown in plan in Fig. 2 and vertical section in Fig. 3, each tile is formed with recesses to fit a pair of tubes 5 screwed into the channel 6 and in addition with notches 8 to allow air circulation in the hollow wall. Additional air is supplied to the tubes 5, as by nozzles 12, either exhausting into the hollow wall or, as shown, going in by one tube and out by the other through a connecting recess 4a in the tile; or the tubes may merely have controllable air-inlet slots. Each tile may be in two parts-inner and outer-scarf-jointed together and locked by means of a brick projection from the outer wall or by a metal key secured to the channel 6. To prevent the tiles from slipping the tubes 5 are slightly inclined, e.g. by tilting the channel 0, as shown, or by securing them in slightly-inclined holes in brackets bolted to the channels.

The capacitor is said to intensify the spark in the gap. In an embodiment a cap 32 having a body 34 of fibre reinforced plastics, silicone rubber or ceramics has a terminal 36 and a slotted annular connector 38. A capacitor 50 is connected to lead 48 of the cap and via an outer conductor lead 54 to the metal shield 22 of the sparking plug 20. In some embodiments, the cap body 34 is a solid insulator with either the capacitor buried directly therein (Figures 8 and 10, not shown) or in a cavity filled with epoxy resin (60, Figures 4, 7 and 9, not shown). Instead of an annular connector 38 to ground the capacitor, some embodiments use a spring (56, Figures 3 to 11, not shown) the spring also acts as a heat dissipator to protect the cap 32. The H.T. lead 40 may be joined directly to the cap rather than by terminal 36 (Figures 7 to 10). A plurality of capacitors may be used (Figure 10) and instead of a flat capacitor, one having a cylindrical dielectric with the electrodes on the upper and lower surfaces (90a, 90b, Figures 11 and 12, not shown) may be used. A resilient sleeve (64, Figure 6) may be provided at the bottom of the cap to grip the top of the sparking plug and prevent ingress of dust and moisture, while an insulating sleeve (102, Figure 11) may be placed around the cap body. In one embodiment (Figure 9) the capacitor is grounded via a conductive ring (70) and leaf springs (68) which directly contact the engine block.

Title: Apparatus and method for forming pellets of organic thermoplastic material
IPC: B29B9/06
Filed: 1957-02-22
Abstract: 860,827. Extruding pellets. EASTMAN KODAK CO. Feb. 22, 1957 [Feb. 23, 1956], No. 5983/57. Class 87(2). A method of forming pellets from a semimolten organic thermoplastic composition containing a gas under a disruptive pressure, e.g. polyethylene containing unpolymerised ethylene comprises extruding the composition directly into a column of inert liquid, e.g. water, having a hydrostatic pressure at the point of extrusion greater than the pressure of the gas and at a temperature less than that of the material, cutting the material at the point of extrusion whilst immersed in the liquid, permitting the pellets to rise in the column of liquid, maintaining the hydrostatic pressure on the cut pellets during the rise in the liquid until the pellets cool to a non-deformable state, conducting the pellets out of the liquid and then drying the pellets. An apparatus is claimed which comprises an extrusion head 10, with heaters 11, 12, a screen 14 and an annular discharge passage 16 in communication with a series of circularly-spaced die orifices 18 in a die plate 17. A cutter plate 22, with heating passages 26, and a similar series of die orifices 29, is bolted to the extrusion head 10 and is insulated from the die plate 17 by a gasket 20. The cutter plate 22 is part of the side of a liquid container 45, with liquid inlets 40, 50 having a horizontal top portion 48 with a weir 49 discharging on to a mesh conveyer 51 having a drain trough 53. A rotatable cutting head 31, with a liquid discharge opening 38, has spring loaded cutting blades in contact with the exit face of the cutter plate 72. In operation, plastic material passes through the screen 14 into the annular passage 16, separates into rods in the die orifices 18, 29, is cut into pellets by the rotating blades where the flow of liquid through the opening 38 sweeps the pellets clear of the blades and separates them, they are then carried upwards by the flow of liquid from the inlets 40, 50 to discharge over the weir 49 to the belt 51 where the liquid passes to the trough 53 from whence it may be recycled. Thermoplastic materials pelleted may be vinyl chloride, methyl methacrylate, styrene, cellulosics and polyethylene. The pressure of the column of liquid in the container 45 is such as to be greater than the internal pressure of the ethylene gas contained in the pellets so that the gas does not rupture the pellets but diffuses out when the pellets are at least partly solidified. The temperatures of the liquids and thermoplastics are such that on reaching the belt 51 the pellets have sufficient latent heat to be self drying but other drying means such as hot air jets, infra-red lamps, steam coils or electric heaters may be used. A further apparatus may be used (not illustrated) wherein the rods of thermoplastic material are discharged radially from the cutter plate to be cut by blades moving around its circumference.
