Title: Improvements in or relating to panel-like articles and methods of making the same
IPC: B60R13/02
Filed: 1949-01-28
Abstract: 663,271. Compound sheet materials. BRIGGS MANUFACTURING CO. Jan. 28, 1949 [Jan. 30, 1948], No. 2444/49. Class 140. [Also in Group X] A panel-like article comprises a stiff foundation sheet 10, a cover sheet 13, an intermediate padding sheet 12 underlying the cover sheet and in contact therewith, and an absorbent compressible paper sheet 11 interposed between the foundation and padding sheets, and containing a resinous material, the sheets being bonded together under the influence of heat and pressure, solely through the medium of the resinous material. The foundation sheet 10 may or may not be treated, as with resin or asphalt material, to increase its moisture resistance; it may be a heavy fibre composition board, such as " Masonite " (Registered Trade Mark). The paper sheet 11 is preferably a low density, compressible and absorbent sheet of cellulosic material such as alpha-cellulose or pulp paper, and is impregnated, preferably with a thermosetting resin such as a phenol-formaldehyde product, in the form of a varnish, and dried. The wadding or padding layer 12 may be cotton batting or other soft material. The outer covering sheet 13 may be of fabric or other decorative material. The assembled sheets are consolidated together in a press having heated platens or dies, which apply pressure at selected localities, e.g. to form indentations or grooves as at 14, at which the resin penetrates into the various sheets, and unites them. If the foundation sheet is provided with apertures, as at 15, portions of the overlying layers may be pressed into these, forming a knock-out piece 17 for subsequent removal.

Filed: 1924-01-31
Abstract: 210,789. Torda, T. Jan. 31, 1923, [Convention date]. Alternating-current commutator and induction machines.-In an induction motor in which the rotor acts as the primary member and carries a phase-compensating commutator winding n located on a smaller radius than the polyphase winding y, tappings on the commutator winding are connected with tapping points w on the polyphase winding so that the commutator winding is subjected to less than the full line voltage, and' the commutator brushes are connected with terminals of the stator secondary winding m. Specification 205,776 is referred to. According to the Specification as open to inspection under Sect. 91 (3) (a), the rotor may be the secondary member, in which case tappings on the commutator winding are connected with the individual phases of the polyphase winding at points which are situated as far as possible from the slip-rings. As shown in Fig. 1 (Cancelled) the ends w of the three-phase, rotor winding y are connected to points on the commutator winding n. The brushes b are fed at reduced voltage directly or indirectly from the stator, or from a separate transformer. Where the rotor windings are in delta, the middle points of the phases are connected to the commutator winding. The slip-rings are connected to starting resistances, and short-circuiting and brush-lifting devices may be provided. This subject-matter doesnot appear in the Specification as accepted.

Title: Purification of ª‰-ionone
IPC: C07C403/00
Filed: 1947-02-01
Abstract: b -Ionone is purified by contacting a solution of b -ionone with a chromatographic adsorbent, washing the impurities from the adsorbent, eluting the b -ionone from the absorbent and evaporating to give a b -ionone concentrate.  The impurities are preferably washed from the adsorbent by means of a non-polar solvent (e.g. petroleum ether) and the b -ionone is eluted by a polar solvent.  In an example, b -ionone in petroleum ether is adsorbed in a column of sodium aluminium silicate, the column is washed with petroleum ether, the bulk of the b -ionone is eluted with ether and the final impurities are washed out with acetone. Instead of sodium aluminium silicate, magnesia, tricalcium phosphate, zinc carbonate, calcium hydroxide, activated carbon, aluminium oxide or silica gel may be used.
