Abstract: 1,247,046. Centrifugal fans. FULLER CO. Oct.23, 1968 [Nov.16, 1967], No.50357/68. Heading F1C. Apparatus for maintaining a substantially constant flow in a system fed by a fan comprises a Piezo meter ring attached to the inlet cone of the fan and communicating with the interior of the cone through a number of pressure ports for sensing changes in flow through the cone, and means for automatically controlling the flow in response to changes of flow sensed by the Piezometer ring. A fan 2, Fig.1, supplies cooling air to a cooler 14, the air passing upwardly through a reciprocating grate 15 to cool hot material fed to the cooler from, e.g., a rotary kiln 17. Change in flow resistance caused by variation in the amount of material in the cooler 14 produces a change in flow which is sensed as a change in pressure within the inlet cone 3, Fig.2, by means of a Piezo-meter ring 7, Fig.3, communicating with the interior of the inlet cone through pressure ports 8. A controller 11 converts the pressure changes to a pneumatic or electric signal which controls a damper 5 at the fan outlet so as to compensate for the change in flow resistance. Instead of the damper 5, a flap valve on an atmospheric bleed valve may be used on the speed of the fan or the reciprocating grate may be varied.

Filed: 1967-11-13
Abstract: 1,241,419. Casting decorative articles. S. TIES, and G. N. TAYLOR. 5 Nov., 1968 [13 Nov., 1967], No. 51421/67. Heading B5A. [Also in Division B6] Decorative articles are produced by temporarily securing a sheet of etchable material by one face to a support, forming a pattern on the opposite face of the sheet in an etch-resistant material, etching away completely those parts of the sheet unprotected by the etch-resistant material to form voids extending completely through the sheet, applying over the opposite face of the sheet a settable bonding material to form a layer over the opposite face, the settable material forming a durable bond to only the remaining pattern parts of the sheet and also filling the voids so that it is level with said one face, ensuring that the applied material is set and then stripping the support from the bonded pattern. As shown in Fig. 1, sheet 1 which may consist of a foil of copper or brass is temporarily secured to support 2, by a double-sided adhesive film consisting of a thin flexible film of synthetic plastics material coated on both sides with a layer of adhesive 4. A design of etch-resistant material 5 is then formed on the sheet 1, e.g. by photographic means or by means of a silk-screen process. The sheet is then etched, the etchant acting to remove only those parts of the sheet unprotected by the etch-resistant design until the entire thickness of the sheet has been removed in the unprotected areas. The sheet 1 is then coated with a layer of setting material 7, as shown in Fig. 5, which is preferably coloured to present a contrasting appearance in relation to the material of the sheet 1 and may be an epoxy resin loaded with a pigmented filler. The resin layer is then subjected to heat in order to set it or alternatively cold-cured. The sheet 1 is then stripped from the support to produce the decorative panel. A preservative lacquer may then be applied or the panel may be subjected to a plating or polishing process. Cylindrical articles may be produced by using a support having a face of a required configuration, the support being supported on that face. In the case of a concave face settable material may then be poured into the interior of the article after the etching step to form a solid core. Alternatively a layer of the settable material may be formed over the inside surface of the etched sheet to form a hollow article. The settable material may be loaded with fibreglass.
