IPC: H04R7/18
Filed: 1928-04-28
Abstract: 289,489. Soc. Francaise Radio-Electrique. April 29, 1927, [Convention date]. Diaphragms; loud-speakers. - In order to render an acoustic instrument employing a free-edged large diaphragm less fragile, the whole or part of the periphery of the diaphragm is arranged in contact with soft material such as rubber or felt. In one arrangement, the periphery of a conical diaphragm is supported in contact with a ring of soft rubber or felt which is held in a channelshared member supported on arms radiating from the acoustic instrument. In the modification shown in Fig. 2, two rings A of solt material are carried in the openings of a casing B<1> for the diaphragms E. Further rings A may be provided in the casing for additional diaphragms. The contact between the diaphragm and the supporting ring may be rendered discontinuous. The Specification as open to inspection under Sect. 91 (3) (a) states that the diaphragm may have the form of a pyramid or paraboloid. This subject-matter does not appear in the Specification as accepted.

Title: Improvement in optical comparator
IPC: G02B21/00
Filed: 1943-08-03
Abstract: 568,584. Optical comparators. AMERICAN MEASURING INSTRUMENTS CORPORATION. Aug. 3, 1943, No. 12545. Convention date, June 25, 1942. [Class 97 (i)] [Also in Group XIX] A comparator for testing the thickness of work pieces whereby those which depart from the thickness of a standard piece by more than a plus or minus tolerance may be rejected is adapted, through an optical system which includes a tiltable mirror, prisms and lenses, to project an image of a graticule on to a translucent screen. This image may be viewed directly through an eyepiece or the path of the rays from the image to the eyepiece may be shut off and the rays diverted through other prisms and lenses to form an image, which, if desired, may be enlarged, on a second screen. The graticule 60, Figs. 6 and 9, is formed on a translucent screen 59a secured in front of an aperture 62 and having a prism 59 secured thereto. Light from source 51, Fig. 10, passes through a condenser 54, prisms 57, 59, graticule 60, prism 50 and lens 41, Fig. 1, and is reflected back from the tiltable mirror 40. This mirror is mechanically connected to a feeler 30 which engages the standard piece supported by a table 15. The ray reflected from the mirror returns through the prism 50 and forms an image 93, Fig. 10, on the screen and, if a prism 68 is moved out of the parts of the ray, this image may be viewed through an eyepiece 67. Positive and negative limit indicators are adjustably mounted adjacent the graticule and a zero arrow point 95, Fig. 9, is marked adjacent the image. The standard piece is now removed and the piece to be tested is inserted. The position of the image of the graticule is then compared with that of the image originally formed. The prism 68, Fig. 10, may be moved into the path between the prism 59 and eyepiece 67 to deflect the ray through condenser 96, prism 63, mirrors 80, 82 and 84 to form a second image on a screen 86. A lens 89 may be moved into position between the mirror 84 and screen 86 to form an enlarged image.

April 24, 1930, No. 12693. Convention date, April 24, 1929. [Class 64 (ii).] In controlling or measuring temperature in the range 80-150‹ C., an electric discharge device is used, the evacuated envelope of the device containing a cathode having a layer of alkali material emitting an effective thermionic current varying with the temperature. In heating liquids, the discharge device 1, Fig. 4, is inserted into the heat-insulated liquid-container 14 and is connected in circuit with a source 18 of electric current and with a current meter 19. The meter is calibrated to read temperatures or controls the fuel supply to a burner heating the liquid. The discharge device may have a standard four-pin cap 3, Fig. 1, one pin being connected to the central anode 5 and the other pins being dummies. The cathode 4 is coated on the inside of the envelope 1 and is connected to a sealed lead 7. In forming the cathode, silver or platinum may be dispersed on to the glass, or a solution containing silver, platinum or graphite may be painted on prior to depositing silver electrolytically. After baking, the silver is oxidized by a high-voltage discharge in oxygen, the oxygen is removed and caesium or rubidium is then freed by heating by high-frequency currents a capsule 9 containing caesium dichromate and silicon. The cathode so formed may comprise caesium oxides and may be activated by maintaining for several minutes at 200‹ C. In a modification, the cathode is within the envelope and the alkali layer is deposited on a copper, nickel, tungsten molybdenum, silver or silvercoated electrode in the form of a semi-cylinder, a flat plate or several angularly-disposed plates. Specification 303,476, [Class 39 (i), Electric lamps, Arc &c.], is referred to.

[Also in Division B8] Fibrous materials, e.g. wool, are compressed in a flexible air-tight container or bag 3, fluid is evacuated from the container and the pressure of the atmosphere is thereby allowed to reduce the volume of the container and compress the material. The bag 3 is supported in a metal bin 1 let into a floor 2, a part 5 of the bin being hinged at 6 for removing the filled bag. The upper edge of the bag is held in position by a rubber ring 4. An evacuation pipe having a manually retractable foot, Fig. 3 (not shown), is lowered into the bag before the wool is fed in. The bag mouth is secured round the pipe and air is evacuated from the bag through the pipe. The pipe with the packaged wool attached is raised by means of a block and tackle 16 on a gantry 17, Fig. 2. After removal from the bin, the package is enclosed in a jute sack or in steel bands, the foot 10 is retracted, and the pipe 8 withdrawn before the sack flaps are closed. Air may then be re-admitted to the bag by puncturing the bag wall. The bag may be of polyethylene film, polyvinyl acetate film or regenerated cellulose film.

This may be accomplished by giving the upper part of the chamber improved insulation compared with the remainder and providing a fan to direct air over the outside surfaces. In addition, the upper interior surfaces of the chamber may be roughened, e.g. by sandblasting, to render the formation of water droplets thereon less easy.
