Abstract: 359,525. Sharpening saws. BOOTH, N. A., Cairnhill Street, Maori Hill, Dunedin, New Zealand. July 18, 1930, No. 21793. [Class 83 (iii).] A device for attaching to a file to enable it to be guided by ocular judgment while sharpening the teeth of saws, comprises, in its simplest form, a flat plate and a boss to hold the file in the correct working position. The plate is maintained parallel to the surface of the saw while cutting and the edge A, Fig. 2, used as the top or guiding edge for the alternate teeth on one side of the saw, the other edge A<1> being used as top edge when the saw is reversed. Fig. 4 shows an arm C carrying the file boss pivoted to the plate so that it can be adjusted for different cutting angles. A similar device modified for sharpening the teeth of circular saws is shown in Fig. 8, in which an adjustable pointer K is provided to ensure that the same amount is filed off each tooth ; the flat file H used in this case is held in an adjustable carrier D clamped by a screw E and having a scale for setting the file to the required angle.
Patent GB-655612-A (GB)
Title: Improvements in or relating to moisture vapour-permeable, waterproof, films or coatings
IPC: D06M13/02
Filed: 1947-08-08
Abstract: A composition which may be formed into sheets or coatings comprises a hydrophobic aerogel and a latex of a synthetic rubber or synthetic resin.  The sheets or coatings formed will readily transmit moisture vapour but prevent the passage of liquid water. The aerogel may be silica aerogel, rendered hydrophobic by treatment with an alkoxy chlorosilane or an alkoxy aminosilane such as ditertiary-(butoxy or amoxy)-diaminosilane.  The hydrophobic particles may be mixed with the latex containing a dispersing agent such as methyl cellulose, polyvinyl alcohol, or zinc di-2-ethyl hexyl sulphosuccinate. Alternatively the hydrophobic particles may first be dispersed in water containing the dispersing agent to form a cream which is added to the latex. The latex may contain a polyvinyl compound, poly-butadiene, neoprene, or the substance sold under the Registered Trade Mark "Vistanex" alone, in admixture with one another or with natural latex.  Fibres, e.g. glass, resin, asbestos, or paper fibres, may be added, as may the usual vulcanizing ingredients, antioxidants, colours, and dyes such as methylene blue.  The Specification as open to inspection under Sect. 91 comprises also the use, instead of aerogel particles, of diatomaceous earth, silex, flyash, tripoli, or ordinary silica gel.  This subject-matter does not appear in the Specification as accepted.  Reference has been directed by the Comptroller to Specification 655,677.ALSO:A film, sheet or coating, which readily transmits moisture vapour but prevents the passage of liquid water comprises hydrophobic aerogel particles bonded in a material formed of the solids deposited from natural or synthetic rubber latex.  The aerogel may be silica aerogel, which is rendered hydrophobic by adding thereto 8-15 per cent of an alkoxy chlorosilane or an alkoxy aminosilane such as di-tertiarybutoxy or amoxy) - diaminosilane and thoroughly mixing in a tumbler.  The hydrophobic particles may be mixed directly with latex containing a dispersing agent such as methyl cellulose, polyvinyl alcohol, or zinc di-2-ethyl hexyl sulphosuccinate.

Title: An improved launching or engine-testing platform for vertical take-off jet-propelled aircraft
Inventor: FLETCHER JAMES
IPC: E01C9/00
Filed: 1959-06-25
Abstract: 886,204. Vertical take-off aircraft launching platforms. SHORT BROS. & HARLAND Ltd. Aug. 30, 1960 [June 25, 1959], No. 21868/59. Class 4. A platform for use by vertical takeoff aircraft with downwardly directed direct lift engines, comprises a substantially horizontal frame carried on a sub-structure at a height above ground level, the parts of the frame on which the aircraft is to stand having a reticulated material thereacross, the density of which is such as to cause a substantial pressure drop in the gas effluxe stream passing therethrough, the gas stream being conducted away beneath the frame. By this means, recirculation of exhaust gases into the engine air intake, and downward suction effects on the aircraft wings, are avoided. Fig. 1 shows the platform in plan, and Fig. 3 is a partly broken away view in plan of one panel of the platform. In Fig. 3, the substructure comprises spaced parallel channel members 20 resting on pads 21 on the ground, and covered by metal sheeting 201. Above each pad is a pillar 22, the pillars being connected by bracing struts 221. Girders 23 on pillars 22 extend at right angles to members 20, and are overlaid by three grid units 24 (two shown in part). The central panels 28, Fig. 1, have a steel mesh covering, through which the engine exhaust gases may pass. The remaining panels 25, are covered by sheet metal plates 26, Fig. 3. Access to the platform is provided by sloping ramp sections 31, Fig. 1, of which the grid units have no covering, to allow free lateral passage of the exhaust gases from under the platform. Alternatively, the ramp members may be hinged to the platform, and be raised to horizontal positions flush with the platform to allow lateral passage of the gases. To prevent the gases from issuing from the upwind side of the platform vertical sheet metal flaps may be inserted between the platform and the ramp. Where no ramp is used, such flaps may be hinged at their lower edges to the platform, so as to lie flat on the ground when not in use. Pads 30 are mounted on the platform, Fig. 1, being composed of spaced sheet metal plates interleaved with asbestos sheeting, to protect the landing gear tyres from the head of the exhaust gases flowing beneath the platform.
