Abstract: 441,204. Discharge lamps. UNIVERSAG TECHNISCHE AKT.-GES., Glarus, Switzerland. July 12, 1934, No. 20485: Convention date, July 13, 1933. Drawings to Specification. [Class 39 (i)] In producing light by converting electric energy in an accelerating space into kinetic energy of primary electrons which enter a field-free, gas or vapour filled lighting space and lose their energy therein, the voltage accelerating the electrons is much higher than the cathode drop in arc discharges and is preferably 50-300 volts, the gas pressure is adjusted so that the primary electrons lose most of their energy before reaching the walls of the lighting space and the electron current is so high that a " plasma " with an electron concentration above 10<11>-10<12> per c.c. is produced in the lighting space and that the efficiency is much higher than when a current of a few milliamps. is used. The primary electrons energize the electrons of the plasma but may also lose energy by colliding with the walls, which may be provided with fluorescent material. When A.C. is used, flicker may be reduced by allowing such collisions with the walls at the peak voltages. The lighting space may contain a mixture of gases, for example, of sodium, neon and mercury to obtain white light. The lamp bulb is spherical or pear-shape and a parallel beam of primary electron is emitted by a large heated tungsten cathode which avoids the formation of an arc and which is associated with an anode in the neck of the bulb. The primary electrons are accelerated in a thin space-charge sheath on the surface of the cathode and a plasma at the potential of the anode fills the bulb. Such a lamp, filled with neon at À5 mm., gives an efficiency of 11-12 lumens per watt when operated at 70 volts and À6 amps. and no ballast is required. A filling of mercury at 1À9 x 10-2 mm. at a temperature of the lighting space of 200‹ C. is also specified. Theoretical explanation and a formula for the determination of the gas pressure are included.

Title: Manufacture of new esters of compounds of the oestrone series
IPC: C07J75/00
Filed: 1937-07-30
Abstract: Esters of the aestrone series are prepared by causing a compound of the aestrone series to react with an acylating agent of the fatty acid series having in its acid residue more than three carbon atoms. By compounds of the aestrone series there is comprised those compounds of the aestrin series containing a keto group at the 17-position of the cyclopentanopolyhydrophenanthrene nucleus. Compounds of this series mentioned are aestrone, equiline and equilenine.  Suitable acylating agents are the fatty acids themselves, or their anhydrides, halides or esters formed with alcohols of low molecular weight (exchange esterification).  The fatty acids may have a straight or brached chain, and may be saturated or unsaturated.  Acids specially mentioned are butyric, valeric and capric acid.  In examples: (1) aestrone is esterified in the presence of pyridine with n-butyric anhydride for 1 1/2 hours at 110 DEG  C.  The ester crystallizes on dilution with water and is purified by crystallization from hexane.  In a similar manner the isobutyrate and the stearate may be obtained.  Instead of n-butyric anhydride, methyl-n-butyrate may be used as the acylating agent.  In the place of pyridine there may be used dimethylaniline or quinoline, or the reaction may take place in the absence of a base; (2) aestrone is esterified in the presence of dry pyridine with n-valeric chloride, and worked up as in example (1).  Instead of n-valeric chloride, the corresponding bromide may be used.  In a similar manner, aestrone caprate may be obtained.  As acylating agents there may also be used compounds which contain the radical of crotonic, angelic, isovaleric, capronic, caprylic, or lauric acid.  A sample has been furnished under Sect. 2 (5) of aestrone-n-aenanthate prepared by esterifying aestrone with aenanthyl chloride (heptyloyl chloride) at room temperature.
