Title: Improvements in or relating to high temperature refractories
Inventor: SHAW CLIFFORD
IPC: C04B35/48
Filed: 1955-11-21
Abstract: A high temperature refractory body is obtained by mixing zirconia and alumina with an alkyl silicate, water and a mutual solvent, allowing the silicate to set by hydrolysis, heating the mixture to complete the hydrolysis and remove the alkanol formed, the alumina being present in an amount of at least 28 per cent. and the zirconia considerably in excess of the alumina.  A gelling accelerator for the silicate, e.g. dicyclohexylamine or piperidine can also be present, see Specifications 575,752 and 612,622 [both in Group IV].

Title: Improvements in and relating to methods of recording and reproducing sound
IPC: G11B5/70
Filed: 1933-11-30
Abstract: 434,477. Magnetic sound - records. BRITISH THOMSON-HOUSTON CO., Ltd., Crown House, Aldwych, London.-(Assignees of Allgemeine Elektricitõts-Ges.; 2, Friedrich Karl-Ufer, Berlin) Nov. 30, 1933, No. 33639. Void [Abridged as open to inspection under Sect. 91 of the Acts, May 31, 1934]. [Class 40 (ii)] A carrier for a magnetic sound - record consists of a strip of non-magnetic material, such as paper, coated with a layer of pulverized ferro-magnetic material which is magnetically homogeneous. The powder may consist of particles of " carbonyl-iron powder" having a substantially spherical form. Several methods of carrying out the invention are described. For example, the particles may be subjected before and/or during the manufacture of the coated strip to a magnetic field, in such a manner that the particles are sorted according to size and permeability, or that the quantity applied to the strip, preferably previously coated with adhesive, is regulated. The particles may be moved past a magnet by an air current. A further method consists in first applying a physically homogeneous layer to a strip, and subjecting it to a magnetic field. A second coating of particles is then applied in accordance with the changes in the flux due to variations in permeability of the first layer, so as to compensate for the lack of magnetic homogeneity of the first layer.
