Abstract: 255,094. Weinheim, E. July 13, 1925, [Convention date]. Coating or impregnating materials in long lengths; compound fabrics. - Fabrics, paper, fibre, &c. are impregnated or coated by allowing the coating &c. material to penetrate into and dry upon a run of fabric &c. which is maintained under a constant and uniform tension. The fabric &c. 2 is led from a drum 1, driven by rollers 20, 21, and passed through pressure rollers 6, 17, the coating material flowing from a container 4 on to the fabric &c. 2 before it reaches the rolls 6, 17. The roller 17 runs on rails 18 and is mounted on the free ends of arms 16 pivotally secured at 13 to arms 12 pivotally mounted on the table 3, the movement of the arms 12, 16 being controlled by a weight 15 carried by a chain 14 secured to the point 13. The coated fabric &c. passes under a strickle board 7, between rollers 8, 19, the latter roller being mounted in similar fashion to the roller 17, and is wound up on the reel 10. In a modification, a compound fabric is formed from two or more strips which are coated as described above, the coated fabrics being led through pressure rollers, waterproofing and adhesive material being applied to the coated fabrics before they pass through the rollers. Reference has been directed by the Comptroller to Specifrcations 26180/10, 4494/15, 122,680, and 122,681.

Bearings, determining; signalling to aircraft ; aerials.-The location of an aerial landing field is indicated to aircraft by an upwardly-extending field of concentrated electromagnetic radiation. A parabolic reflector 16, Figs. 3 and 5, of sheet metal or metal mesh is disposed within a pit 26 at the centre of the landing field, and may be covered with means enabling aeroplanes to pass over it but permeable to electromagnetic radiation. Alternatively, the reflector may be elevated from the ground. At the focus of the reflector is an aerial 17, extending symmetrically on either side of the axis and preferably parallel to the reflector surface. The centre portion of the aerial is inductively coupled to an oscillator 21 supplying energy through a modulator 22 to which is also coupled a low-frequency oscillator 23 giving a characteristic tone-frequency or code-signal. The wavelength used is preferably four times the focal wavelength of the reflector 16, or the latter may be an odd multiple of a quarter of the wavelength used. The beam of radiation so produced is substantially in the form of a cone whose axis is perpendicular to the field surface and whose apex is at the reflector 16. The space covered by the radiation may be extended by inclining the axis 18, Fig. 5, of the reflector to the vertical axis 32, and providing means, such as a motor 33, for rotating the former about the latter axis. A suitable receiving aerial, Fig. 1B, capable of receiving the polarized waves from the transmitter, irrespective of the direction of flight of the aeroplane, consists of crossed horizontal conductors 27, connected centrally to a receiver 28.

The stove shown comprises a body 21 carrying a superstructure 23 with one or more shelves 24. Beneath the closed top 27 and forwardly of its centreline are arranged in the chamber 33 the main burners 32, the portion of the hot-plate to the rear of them being heated by the combustionproducts passing to the outlet 44 at the rear of the chamber. Potholes with rings and covers are provided in the hot-plate 27, the latter forming a substantially smooth unbroken surface when the pot-holes are closed. A small burner 37 is provided in addition to the main burners, for heating a coffee percolator or for similar purposes. Air is admitted to the burners in the chamber 33 through an opening 36 extending approximately across the whole width of the front of the chamber beneath a suspended plate 70. The burners are ignited from a pilot burner 82 which burns normally under a restricted gas supply, but which on the depression of a button 84 admitting gas at full pressure projects a jet towards each burner. The body of the stove forms an oven, at the top of which is a broiling burner 48, whilst beneath the plate 51 is a baking burner 49. Air for combustion is admitted through openings 54 in the bottom plate 55. The. combustion products of the burner 49 pass into the oven through openings 53 in the plate 51 and, as well as those from the burner 48, leave through openings 52 in the partition 50 leading to the outlet 44. The burner 49 carries a perforated ignition tube 88 which can be lit at the opening 53, the flame travelling down to the burner itself. The valve control mechanism 67 of the burners 48, 49 is arranged so that they cannot be lighted simultaneously. Larger ranges are described, having three main burners under the forward part of the top plate and two ovens side by side.
