IPC: C03C27/10
Filed: 1928-06-30
Abstract: 293,052. Soc. d'Etude des Verres et Glaces de S¹retÚ, (Assignees of Duclaux, J.). July 1, 1927, [Convention date]. Compound transparent sheets. - The yellow discolouration of compound glass is prevented by using as the core regenerated cellulose formed from any of its soluble ethers or precipitated from its solutions, particularly cuproammoniacal solutions, or the polysaccharides, notably caroubin. The Specification as open to inspection under Sect. 91 (3) .(a) also comprises the following subject-matter. When celluloid is used, yellow discolouration can be prevented by excluding radiations below the wave-length 3300 A. Suitable substances for this may be incorporated in the adhesive used, such as the mineral salts stannate, antimoniate, molybdate, tungstate; a crystalloid or colloid salt of lead, mercury, molybdenum, thorium, bismuth, uranium, or certain organic compounds such as a ketone of high molecular weight, an aromatic aldehyde, a phthalein, an aromatic hydrocarbon, an aliphatic or aromatic acid possessing a double bond, a ketonic function, a quinone or nitrated derivative of one of its salts, a body with a mixed function, such as citral and dibenzolacetone, or a substituted urea. A faint yellow tint in the protecting product may be neutralized with a stable blue material, such as Indanthrene blue. The colouration may also be prevented in sheets joined together after dipping the celluloid in alcohol or acetone by using the less active propyl, butyl, or amyl alcohols. A small quantity of a hydrocarbon or an oil such as castor oil may be added to diminish the action of the alcohols further. This subject-matter does not appear in the Specification as accepted.

Abstract: 686,594. Pyrometers. LEEDS & NORTHRUP CO. July 25, 1949, No. 19524/49. Class 97 (iii). [Also in Group XL (b)] In a radiation pyrometer in which comparison, of the intensity of radiation of two different wavelengths gives an indication of the temperature, two sensitive devices are provided, each responsive to one of the wavelengths the voltage output of each, for wavelengths whose reciprocals differ by more than unity when measured in microns, being compared. As shown, radiation from the furnace passes through a quartz lens 15 and wavelengths of less than 6000 A are imaged by a lightly gilded mirror 60 on to radially arranged thermocouples 17. Shorter wavelengths pass through the mirror and are brought to a focus in the plane of the filament 51 of a disappearing filament pyrometer which may be of the type described in U.S.A. Specification 1,362,281. The intensity of radiation is reduced by screens 56, 57 of blue green or purple glass and screens 58, 59 in the eye-piece approximate a green glass. The current in the pyrometer may be adjusted by a rheostat 53. The circuit arrangement is shown in Fig. 4, the thermocouple arrangement having the reference 19. Adjustment of ganged contacts 32, 34 maintains the total resistance external to the disappearing filament pyrometer 50 and its rheostat constant and the voltage developed by the filament current is balanced against output of the thermocouple 19 through a mechanical relay 62 which adjusts the slide wire contacts and drives a pen 68 over a chart. This mechanical relay may be as described in U.S.A. Specification 1,935,732.

Abstract: 187,701. Evans, W., and Chappell Piano Co., Ltd. July 22, 1921. Actions, pneumatic.-In an automatic pianoplaying mechanism having piston, striker-devices, the pistons and piston recesses are of elongated or oval form in cross-section so that they may be arranged with one piston for each note side by side in a single row. In the construction shown the playing mechanism is constructed in sections, each comprising five parts secured together by screws, namely, a block 11 containing four striker pistons 10 of elongated cross-section, a cover 12 therefor, a chest 13 containing four valve-operating pistons, a main vacuum chest 14 and a cover 15. Each valve piston 26 is seated in a recess communicating at the bottom with a conduit 27 connected through a gauze screen with a trackerbar orifice, and at the top with a conduit 32 continued in an extension 320 for connection with a low-tension vacuum apparatus. On the piston 26 @ests the stem of a valve 37 guided in a partition 33 above which is a chamber communicating by means of a conduit 132 with a high-tension vacuum apparatus. The cover 15 is formed with partitions dividing it into four compartments each of which has an orifice communicating with a passage 21 in the cover 12 and an orifice 40 open to the atmosphere. In operation air entering through a tracker-bar orifice raises the piston 26 and thereby the valve 37 placing the high-tension vacuum chest 14 in communication with the conduit 21 and thereby causing the striker-piston 10 to rise and operate the striker rod 23 located beneath its appropriate hammer action-lever. The pistons may be faced with rubber pads 17, 18. Instead of employing both high and low-tension vacua, one degree of vacuum may be used, by having the valve stems 36 a slack fit in their guides in the partition 33 or by increasing the free area of the striker-pistons. The 'block 11 is provided with two projections 44 sn that it may be hooked over a supporting rail 46, being secured adjustably thereon by means of a clamping screw passing through a slot in the rail 46 and through an orifice in the block 11. To facilitate lateral adjustment of each block, the distance between the centre of each end striker-rod and the adjacent wall of the block is slightly less than half the distance between the centre of adjacent striker-rods. According to the Provisional Specification the playing-mechanism is a valveless one the bottom side of the striker-piston recesses being formed for connection with the tracker-bar orifices.
