Abstract: 1400542 Creating foam POLYSAR Ltd 10 Aug 1972 [23 Aug 1971] 37389/72 Heading B1C [Also in Division B5] An extruded polymeric material is foamed by a fluid expanding agent e.g. nitrogen, diffused under pressure into the heat plasticised material within the extruder during its labrynthian passage along the contacting surface of a porous sintered member e.g. of Iron/Nickel containing 3.5% Ni and 0.75% C and a density of 7.18 gm/U (92.8% of theoretical maximum). In the described embodiment, the member comprises at least a pair of sequential abutting plates e.g. the four plates 30a to 30d, each provided with a plurality of apertures for the passage of the material and supported in a housing 15, between the extruder screw 12 and die head, by a multi-apertured plate 24 of high tensile steel. The apertures 25 of plate 24 are countersunk at their outlets, and their inlets are aligned with the apertures 31a of plate 30a which are countersunk at their inlets, the remaining 2 plates having apertures 31b to 31d countersunk at both their inlets and outlets and the apertures of adjacent. plates 30a to 30d being offset from each other by half the spacing between apertures in a plate to define the labrynthian passage, so that the material is subjected to a process of subdivision and recombination in passage through the plates Fig. 4 (not shown) to effect a homogenous breakdown and dispersion of entrained lubbles of the blowing agent. The expanding agent is supplied at a passage 40 and distributed to each plate via axial housing grooves 38a to 38c, and circular housing grooves 37 each aligned with an annular plate groove 35a to 35d which each communicate with a plurality of parallel ducts e.g. 36a, extending transversely through the plates between the apertures. The ducts 36a may be interconnected by similar ducts extending normally thereto. The plates are retained within housing 15 by ring nut 23, and their abutting surfaces may be ground, or silver soldered or brazed together, to avoid leakage of the plastics. "C" ring clamps 16 effect attachment between the housing 15, and the barrel 11 and the extruder die. A screen pack may be located upstream of the plate.

A coffee-making machine comprises at least one dispensing head 16, 16<SP>1</SP> in which hot water percolates through a measure of ground coffee, connected to a small capacity hot water container 1 having controlling means to maintain the temperature and pressure at about 1.5 atmospheres and at least 110‹ C. and a steam generator supplying at least one steam nozzle. As shown, water is fed from pump 5 through pressurereducing device 4 and check valve 2 to container 1 where it is heated by an electric heating element 9 controlled by thermostat 10. Container 1 is also connected to a steam generator 6 heated by element 11 and connected by conduits to a pressure meter 12 and a water gauge 13. Steam can pass from generator 6 through a three-way cock 15 into one of two vaporizers 14, 141. Heads 16, 16<SP>1</SP> each have a piston manuallyoperated against a coil spring to operate cocks 18 communicating with cavities 19 which are connected to container 1 to allow hot water to pass to the infusing chamber. An arrangement, Fig. 5 (not shown), may be provided for connecting the cavity 19 with the steam generator 6 .to reduce the pressure of the water for infusion if necessary. In a modification, Figs. 4A, 4B, in the dispensing head the hot water discharge piston 20 is connected to a coaxial piston 21 sliding in a cylinder 22. Movement of a lever 28 to the right against spring 25 causes a part 30 connected to a slide valve 23 to be locked in position to the right of locking bar 29. Cylinder 22 is then connected to the discharge port 41 and piston 21 rises under the influence of spring 27, moving piston 20 with it. As piston 20 rises, a rod 36 secured thereto passes through a hole in the cylinder cover and engages a selected one of three projections 31a, 31b, 31c formed on a ratchet device 31 which is pivoted to an arm 32 of a two-armed lever 32, 33 pivoted to part 4 which is loosely located in a slide 35. When rod 36 engages one of the projections, arm 32 rises and causes arm 38 to be lowered which opens a valve 18 to allow hot water from container 1 to enter the infusion chamber. After a short time latch 29 is lifted, releasing member 30 and allowing valve 23 to return under the action of spring 25 to the position in Fig. 4B which allows liquid under pressure to be fed in above piston 21 so that both pistons move downwards and the hot water is forced out through the coffee grounds
