Title: Improvements relating to porous bodies coated with metal
IPC: C23C18/16
Filed: 1963-08-26
Abstract: In a process for the production of a porous body such as a fuel cell electrode from a particulate substrate material, the substrate is coated with a first layer of at least one metal such as Ni, Au, Ag or Pt group metals by a chemical exchange process and with a second layer of at least one metal such as those above, by a chemical reduction process, the particulate substrate material being sintered either before the first coating, or after the first but before the second coating, or after the second coating.  The substrate may be Ni, Ag, Cu, Ti, Co, Stainless steel, Ta or "MONEL" (Trade Mark) or a non metal such as graphite, polyethylene, P.V.C., glass, Al2 O3 or SiO2 coated with one of the above metals by vapour deposition, sputtering, chemical reduction or thermal decomposition.  The first and second coatings may be of the same or different metals and 25-65% of the coating is applied by the chemical reduction process in which the reducing agent may be hypo-phosphorus acid, formaldehyde, oxalic acid, phosphorus or hydrazine. Examples are given of the formation of a Ag coating on Ni by exchange from a silver nitrate solution and a Pd coating on Ni by exchange from a palladous chloride solution.  Ag is coated on to a Ag coated Ni substrate by reduction of an ammoniacal silver nitrate solution with formaldehyde or by impregnating the Ag coated Ni substrate with phosphorus in carbon disulphide to deposit the phosphorus and then adding silver nitrate solution which was reduced by the phosphorus. Pd is deposited from a complex ammoniacal palladium chloride solution using E.D.T.A. and hydrazine.  The coated powders are pressed to shape and sintered in hydrogen.

The levers 32 are connected by a crosshead 34 secured to the plunger rod 33 which has a spherical end 42 loosely pivoted to the plunger 40. The burner 23 is connected to the vaporizing channel 25 through a valve having an operative knob 28 which may either be telescopically mounted on the valve spindle so that it may be moved within the casing walls when not in use or be removable. The knob shown in Fig. 3 is fitted with a spring plate 29 adjacent an axial aperture to engage resiliently a flat on the end of the valve spindle 27. The stove casing consists of a top plate 11, end plate, bottom plates 14, side plates 10, a baffle 63 extending around three sides of the burner 23, and a hot plate 54 which may be slid to the position shown in Fig. 1 where lugs 56 on its edge engage apertures in the top plate and hot gases from around the burner can pass through an aperture 53 in one side plate 10 to a pot placed over an opening 58 in the hot plate. The opening 58 may be fitted with a removable cover plate 59.

Yarn is fed to a container to be piled therein by a stream of gas, with relative movement being effected between the yarn and container to cause the yarn to be piled evenly. As described an air feed nozzle 16 is used. Pressure of the air may be controlled by having a rotatable apertured disc above and contiguous with apertured plate 29. The relative movement between the yarn and container may be obtained by: (a) reciprocating nozzle 16 on a carriage which is reciprocated in a traverse direction to the reciprocation of the nozzle, (b) swinging the nozzle, (c) swinging a flexible extension of the nozzle using a follower engaging in an endless groove of a rotatory scroll which may also be reciprocated, (d) a movable guide, or a plurality of intermittently operable air jets, between nozzle 16 and the container, or (e) rotation of the container optionally combined with movement of the nozzle or guide. The yarn may be compacted in the container by sucking air out of a wire-mesh base of the container having sides of steel, or out of the bottom of the sides if they are also of wiremesh. The container also has a hinged lid and lips on the two sides for engagement with a dye vat. Nozzle 16 draws yarn off the bobbin in:a rotatory magazine, the yarn passing over a guide wheel, and a feeler to detect broken ends and slubs. The upper or lower sections 18, 19 of the nozzle or a guide eyelet may be of such a size as to prevent passage of yarn knots of two great a size. When withdrawing yarn from the container after dyeing suction is applied to the container to obtain even withdrawal, the yarn passing to a winding station via a pair of squeeze rolls and heated rolls to dry the yarn.

Abstract: 1,253,311. Sachets with drinking tubes. VERPACKUNGS-UND SCHOKOLADENMASCHINEN DRESDEN VEB. 9 July, 1969, No. 34631/69. Heading B8C. A process, for the production of sachets for beverages in a machine which forms a strip of material into a tube over a shaping shoulder and introduces liquid into the sachets through a filling tube after they have been successively partly formed by transverse seams produced in their bases, is characterized in that the filled sachets are removed from the machine before the upper sealing seam has been produced each sachet then being clamped adjacent its upper end, somewhat below the upper edges, by a pair of clamping bars 5, 5, and having its upper ends, which project beyond the bars, spread apart by a suction device 22 arid provided with a drinking tube the upper end then being sealed by two transverse welded seams which enclose the drinking tube between them. As the base of a sachet is seamed by welding tools 6, Fig. 3, separating tools 7 cut off the preceding sachet S which is gripped by one pair of clamp'bars 5 below its upper edge. Rotation of the rotor 1 through 90 degrees presents the sachet S at a drinking-tube insertion station 2 where the upper projecting ends of the sachet are drawn apart in V-formation by the suction bars 22 and an insertion plate 23 is moved, by a driving shaft 27 and a toggle joint 26, to cause a drinking tube, lodged in a slot in the plate 23, to fall into the open V-shaped portion of the sachet S, suction through the bars 22 at the same time being stopped. The plate 23 is then retracted to its original position beneath a feed hopper 21 to pick up another drinking tube in its slot. Further rotation of the rotor 1 through 90 degrees moves the sachet to a welding station 3 where a pair of heated welding bars 31, operated by a lever drive 32, are brought to gether to enclose the drinking tube between upper and lower seams. The lower branches of the welding bars 31 may be interrupted to provide a gap in the lower seam which provides communication between main body of the sachet and the space between the upper seams which houses the drinking tube. In this manner the contents of the sachet are accessible by push ing one end of the drinking tube outwards through the package. The welding bars 31 are moved apart and the rotor 1 is again turned through 90 degrees to a fourth position where the clamping bars 5 are opened and the sachet is delivered, by way of a shoot 42, to a delivery belt 41. The rotor has a pair of clamping bars mounted at each of its four sides which successively pass through the four operating stations.
