Title: An improved process for the manufacture of mono-sodium glutamate and like glutamic acid salts
Filed: 1930-01-23
Abstract: In the production of salts of glutamic acid such as monosodium glutamate by hydrolysing gluten flour with hydrochloric acid, neutralizing the hydrolysate, and treating the glutamic acid formed with a suitable base, decomposition of the amino-acids and loss of hydrochloric acid while concentrating the hydrolysate by evaporation is prevented by carrying out the evaporation in vacuo at a low temperature.  According to an example, gluten flour is mixed with concentrated hydrochloric acid and allowed to stand until the mass becomes liquid.  The mixture is boiled for six hours under reflux, then filtered hot, and evaporated to half its volume in vacuo at 45 DEG  C.  The concentrate is mixed with an equal volume of concentrated hydrochloric acid and allowed to stand until glutamic acid crystallizes out.  The crystals are filtered, washed with hydrochloric acid, dissolved in boiling water, and the solution is treated with decolourizing charcoal.  The decolourized solution is filtered, and the exact quantity of caustic soda required to neutralize all the free and combined hydrochloric acid is then added. The liquor is cooled and the precipitate of glutamic acid is removed therefrom and dried.  A weighed quantity of the precipitate is suspended in water, the exact quantity of caustic soda required to form monosodium glutamate is added thereto, and the solution is evaporated in open pans until the salt sets to a crystalline mass which is then broken up and powdered.  By using the hydroxides or carbonates of such metals as potassium, calcium, or magnesium instead of caustic soda, the glutamic acid salts of these metals can be obtained.

Title: Improvements in Apparatus for Producing Flashes by the Electric Volatilisation of Fusible Wires.
Inventor: COURTIER JULES
IPC: F21K5/08
Filed: 1918-02-12
Abstract: 122,719. Courtier, J., and Courtier, P. Feb. 12, 1918. Spark lamps.-A device for producing flashes by the electric volatilization of fusible wires, for instance of aluminium, copper, or magnesium, comprises an insulating support with eyelets for attachment of the wires, another support for conductive plugs engaging the eyelets, and a current distributor allowing a variable number of wires to be volatilized at each operation. In one arrangement,-the wires C, Fig. 4, connect a circular row of eyelets B in a cardboard disk A to a central eyelet. Plugs E, which may be spring- urged, are mounted on an insulating base D and enter the outer eyelets B, while a pin G inserted through a central eyelet into a socket H in the base presses the disk A towards the base. The socket H is directly attached to one conductor, and the plugs E are connected to a row of contacts M, Fig. 5, on a plate I. A switch arm J carrying a brush N is held by a catch P which can be disengaged by a Bowden wire U. A spring L then rotates the switch arm, which sweeps over the contacts M until a stud T on the switch arm meets a stop arm Q, retained in the desired position by a pin R inserted in one of a number of holes S. In another arrangement, the wires are, in series between eyelets b, Fig. 9, in a flexible band a, which in being wound off a drum W on to a drum W<1> passes over a wheel i carrying studs e. These studs engage the eyelets and are attached to contacts m successively engaging a pair of brushes, n, n. A pinion X on the wheel i gears with a toothed wheel Y which is driven by a spring l wound by a chain o and connected to the wheel Y by a ratchet-wheel and pawl y<1>. A catch y<11> acting on the ratchet-wheel can be withdrawn eleotro-magnetically. The amount of rotation and consequently the number of wires volatilized is determined by one or other of two wheels Z, Z" geared to the ratchet wheel, the wheel Z rotating more slowly and the wheel Z" rotating more quickly than the ratchet-wheel. A pin t or t' on either wheel is arrested after the required movement by an arm q or q<1> secured by a pin r or r<1> entering holes in an arc V or V<1>, The arm q or q<1> not in use is folded up out of the way about a hinge z or z<1>. A fixed stop arrests the pin t in zero position when the spring is wound up. To use more wires than allowed by the wheel Z, both arms are thrown out of action; still more wires can be burnt by turning the drum W<1> by hand. In another arrangement, the contact wheel is driven by a belt from a crank-actuated shaft on which is a cam periodically closing a switch connected to the brushes. In another arrangement, the wires are transversely or diagonally arranged on the band, and the pairs of eyelets are engaged by studs on a drum having on its ends contacts connected to the studs. A further modification consists in winding the wire continuously around an asbestos or like band and attaching it at intervals to eyelets.
