Title: Improvements in or relating to the manufacture of coverings suitable for floors
IPC: E04F15/10
Filed: 1931-06-04
Abstract: Floor coverings of tiled or like pattern are made by stacking or coiling a series of tesser  of vulcanized rubber &c., coating the exposed edges with raw rubber applied in sheet, paste, or solution form, separating the tesser , assembling them to pattern, if desired on a backing, and vulcanizing them together in a press.  The first stage of the process may be the production of tesser  coated on two edges by winding a strip of vulcanized rubber into a coil, coating the faces of the coil, unwinding it and cutting into tesser ; the second stage then consists in placing the tesser  on a temporary backing strip, winding this into a coil, and coating the faces of the coil (i.e. the two edges of each tessera not previously coated).  In an alternative form of the invention, blocks or strips of raw rubber which may form part of the pattern are interposed between sections of vulcanized material and vulcanized to unite the whole.

Filed: 1944-09-01
Abstract: 576,817. Magnetic tests. EQUIPMENT & ENGINEERING CO., Ltd., and SWIFT, H. B. Sept. 1, 1944, No. 16668. [Class 37] Apparatus for determining simultaneously longitudinal and transverse cracks in iron or steel, comprises four magnetic poles arranged at the corners of a aquare base and having the sequence of polarity North, South, North, South, so that four magnetic paths are formed between the poles in two directions at right angles to each other. Four magnetising coils B, C, D, E, Fig. 2, each having an iron core F with an adjustable extension piece G are mounted at the corners of an iron base A. Four distinct flux paths are formed so that flux passes in two directions at right angles to each other through an iron or steel part H, Fig. 3, to be tested. The coils B, C, D, E may be connected in series or parallel and are so arranged that the coils B, E have North poles uppermost and the coils C, D have South poles uppermost. A longitudinal crack I breaks the transverse flux whilst a transverse crack J breaks the longitudinal flux, so that a polarity is formed across each crack and iron particles are attracted. As the flux paths do not cross each other it is necessary when applying the detecting medium, which may be either liquid or dry powder to move the object slightly sideways so that the whole may be brought under the influence of the flux paths. In a modification only two magnetising coils are used, each magnetising two of the pole pieces, which are mounted on a non-magnetic base. The iron cores and their magnetising coils may be replaced by permanent magnets.
