Abstract: 292,330. Geraghty, W. F. C. May 18, 1927. Crystal and like detectors ; heterodyne receiving systems.-A crystal-metal combination of the type used as a wireless detector is arranged to function as a high-frequency retracting contact, the action being due to physical vibrations set up in the crystal, and the system is then adapted to give heterodyne reception either of telegraphic or telephonic signals. The vibrating crystal contact e is energized at a particular frequency by means of a back-coupled valve oscillator a, and the tuned circuits g are then adjusted to a slightly different frequency so as to produce a heterodyne note in the phones c. The fundamental crystal frequency is stated to be altered slightly by the passage of the rectified signal energy, thus producing proportional alterations in the telephone note after rectification by a standard crystal detector j. Chokes f, f serve to confine the energy from the valve a to the circuit containing the vibrating crystal contact. As the signal input energy is less than the resulting telephone output, the arrangement constitutes an amplifier.

Filed: 1945-05-30
Abstract: Phosphorylated chalkones, possessing therapeutic properties, are manufactured by reacting together, in an alkaline medium, a nuclear substitution product of an aromatic aldehyde and a nuclear substitution product of acetophenone, the nuclear substituents being free, etherified or phosphorylated phenolic hydroxy groups and at least one of the reactants containing at least one phosphorylated hydroxy group, preferably in the form of its di-alkali metal salt. In examples: (1) the di-sodium salt of phosphorylated p-hydroxyacetophenone is reacted with isovanillin in aqueous alcoholic sodium hydroxide solution to produce the trisodium salt of 3 : 41-dihydroxy-4-methoxychalkone-41-phosphate, from which the free acid is liberated by means of dilute hydrochloric acid and is converted into the di-sodium salt by addition of the calculated quantity of caustic soda solution; (2) vanillin similarly yields the di-sodium salt of 4 : 41-dihydroxy-3-methoxychalkone-41-phosphate; (3) p-hydroxyacetophenone and phosphorylated vanillin similarly yield the di-sodium salt of 4 : 41-dihydroxy-3-methoxychalkone-4-phosphate. Phosphorylated hydroxyaromatic aldehydes and ketones are obtainable by treating the corresponding free hydroxy compounds with phosphoryl chloride in the presence of dry pyridine.  The phosphorylation of p-hydroxyacetophenone and of vanillin is described in detail, the reactions being carried out in benzene solution.
