Abstract: 203,105. Dehn, F. B., (Fodor, A.). June 26,1922. Sound-box cases; tool-arms and mountings; sound-boxes, supporting; stands. - Relates to sound-reproducing apparatus of the kind in which, instead of the usual sound-box, tone-arm, and horn, a body similar to a violin is employed, vibrations being transmitted to this body, which emits the sound directly, by means of a stylus. engaging with a record. According to the invention, within the hollow sounding-body is a thin vibratory plate which divides the body into two resonance chambers of different sizes, and which forms a means for transmitting the vibrations from the stylus, the direct acoustic effect of the plate being negligible. The hollow body or box 27 is pivoted at 26 to a pillar which is adjustable vertically in a bracket fixed, in the construction shown; to a table 8 carrying the machine. The inclination of the body 27 to the record can thus be varied. A plate 40 is fixed obliquely across the interior of the box and is connected by a block 47 to the stylus-bar 36. Fig. 1, or to two stylusbars 36, 45, Fig. 6, either of which can be used according to the type of record employed. The stylus-bar or bars, which pass through openings 51 or 52 in the box 27, are mounted by springs such as 33, Fig. 1, or 42, Fig. 6, on brackets 32 secured to the box. The bar 36 is arranged for a stylus intended for use on a lateral-cut record, and the bar 45 for a vertical-cut record. To enable either stylus to be used, when two are provided as shown in Fig. 6, the box is removably mounted on the supporting-pillar, so that it can be reversed. Holes 31, 30 are made in one end wall and in the top of the sounding-box. In a modification, a curved board, sloping from the bottom to the top of the box, is provided in the rear compartment.

Title: The wet spinning of cellulose triesters
IPC: D01F2/28
Filed: 1956-06-07
Abstract: Shaped articles having a basis of a cellulose ester of a monocarboxylic acid, having a degree of substitution of at least 2.7, and preferably 2.85 or more, are made by extruding through one or more shaping orifices a solution of the cellulose ester in a solvent consisting wholly or mainly of methylene chloride into a coagulant consisting essentially of water.  The ester may be a propionate, butyrate, acetate-formate, acetate-propionate or acetate-butyrate of cellulose or, particularly, a cellulose triacetate.  The solvent for the ester advantageously contains a small proportion of a secondary solvent, especially up to 20 per cent by weight, and preferably about 5-15 per cent by weight, of a lower aliphatic alcohol such as methanol, ethanol, n-propanol, isopropanol or isobutanol.  The concentration of the cellulose ester in the solution may be about 15-30 and preferably 19-27 per cent.  The coagulant may be at a temperature of 0-70 DEG  C. and is preferably passed through the coagulating zone at such a rate that all the methylene chloride derived from the spinning solution will dissolve in it.  In example, a solution of a cellulose triacetate in a 90/10 by weight methylene chloride/methanol mixture is spun into water at 20 DEG  C. and the filaments formed are drawn through a column through which water is pumped in the same direction.  After leaving the column the resulting yarn is taken up.
