Title: Improvements in a method of making sodium glutamate
Filed: 1929-02-14
Abstract: 327,810. Fong, Y. S. Feb. 14, 1929. Sodium glutamate is obtained by hydrolyzing substantially dry gluten with hydrochloric acid in the presence of nitric acid or manganese dioxide, converting the glutamic acid by dichloride so formed into glutamic acid, and neutralizing with sodium carbonate, bicarbonate, or hydroxide. In an example, dry gluten prepared by dehydrating wet gluten in vacuo at a temperature not above 75‹ C. is finely ground, screened, and treated under a reflux condenser with concentrated hydrochloric acid to which a little concentrated nitric acid has been added, first at a temperature of about 70‹ C. and finally at a temperature slightly above 100‹ C. until hydrolysis is complete. The liquid is filtered, cooled, and the glutamic acid hydrochloride is allowed to separate. Excess hydrochloric acid may be recovered from the mother liquor. The crude hydrochloride is washed with hydrochloric acid , dissolved in water, and reprecipitated by hydrogen chloride gas, the process being repeated if desired. The purified hydrochloride is dissolved in hot water and neutralized with the theoretical quantity of alkali required to set free the glutamic acid, which is separated by cooling, and completely neutralized with sodium carbonate solution. The liquid is filtered and evaporated, and the mono-sodium glutamate which crystallizes out is dried, ground, and sieved.

IPC: F16D41/12
Filed: 1943-04-08
Abstract: 564,864. Ratchet clutches. WILD & CO., Ltd., M. B., and BOUCHER, J. W. April 8, 1943, No. 5642. [Class 80 (ii)] In a pawl-and-ratchet clutch an inertia. member is utilized to move the pawls into engagement with the ratchet when driving and to hold them disengaged from the ratchet when free-wheeling. As shown, pawls n are pivoted at one end in recesses d in a member c fixed to a shaft a, and co-operate with ratchet teeth f on a driven member b, e, g supported freely on the member c. The portion g has an annular recess i housing an inertia member j which has peripheral recesses k with inclined bases and which correspond in number to the pawls n. Each pawl n has an axially extending projection o bearing on the base of a recess k, thus, when driving, the projections o first slide up the inclined bases of the recesses k until the pawls n engage the ratchet teeth f. If free-wheeling occurs, the projections o slide down the bases until they engage the ends of the recesses k in which position the pawls are held disengaged. An inertia member j may be arranged on both sides of the pawls n. Specification 881/02, [Class 80], is referred to.

Title: Improved device for controlling an adjustable quantity of electrical energy
IPC: H05B6/04
Filed: 1947-02-27
Abstract: 637,240. Annealing. STIVEN, J. Feb. 27, 1947, No. 5724. Convention date, Dec. 11, 1945. [Class 72] [Also in Groups XXXV and XXXVI] A load duration control device functions according to I<SP>2</SP>t with one mechanically driven electromagnet system or (I 1 <SP>2</SP>-I 2 <SP>2</SP> I 2 <SP>2</SP>) with two electromagnetic systems driven mechanically in opposite directions. The invention is described in relation to surface hardening of steel articles by H.F. induction heating mass production processes. In Fig. 1 a constant speed motor 5 drives an electromagnet 4 the windings 3 on which are connected through slip rings 2 and brushes 1 to a rectifier in the supply circuit to the H.F. inductor, Figs. 3, 4 and 5 (not shown). With the steel articles to be surface hardened positioned within the H.F. inductor the supply is switched on and a rotor 6, for example, squirrel cage, within the field of the rotating system 3, 4 then rotates as simultaneously an electromagnet 10 is energized to withdraw a braking block 9 from the braking disc 8 on the rotor shaft. On attainment of a predetermined velocity the centrifugal switch 11 closes contacts 12 to operate a relay whereby the supply is cut-off from the H.F. inductor and electromagnets 4, 10 and the quenching spray brought into operation. Braking block 9 is thus applied to disc 8 and when the speed has decreased to a predetermined limit contacts 12 open to disconnect the supply of quenching liquid. The speed of the rotor 6 may be varied to change the amount of energy supplied to the H.F. inductor by using fly-wheels 13 of different moments of inertia. The amount of energy supplied may also be varied by changing the value of the current energizing the electromagnet 4, for example by a rheostat. The armature shaft may drive a dynamo which energizes the control relay to cut-off the energy supply at a pre-determined speed. Fig. 2 shows an arrangement which utilizes two independent electromagnetic systems 25, 26 rotating in opposite directions with a co-operating rotor 32, 33 in each system. so that shaft 31 is rotated by a torque proportional to the difference of the squares of the currents flowing in each system which currents are derived from a centre tapped transformer/rectifier circuit, Fig. 6 (not shown). The shaft 31 drives a revolution counter 35 which closes contacts 36 to operate a relay which locks and interrupts the supply of energy and brings into operation the quenching spray and a Ferraris motor 37, 38 which reverses the shaft 31 and counter 35 to zero at which point the control relay drops out and thequenching spray is cut off. A permanent magnet brake 34 controls the speed of the shaft 31.

[Class 98 (i)] In photographic apparatus, including copying apparatus, in which the shutter speed is regulated automatically by photoelectric means in order to vary the duration of exposure according to existing light conditions, an indicating member associated with an exposure meter actuated by the photo-electric cell constitutes a non-yielding stop against which abuts an element such as a lever or pin pertaining to the shutter mechanism and determining the shutter setting. As shown, the pointer m is operated by the moving coil l of a moving coil instrument of which the magnet g encircles the lens a. The moving coil l is actuated by current from the photoelectric cell d housed in the lens cover. The pointer m is held fast in operative position by clamping cheeks k pressed together by means actuated when the tripping device e of the shutter is released, and constitutes the stop against which the pin n pertaining to the working mechanism of the shutter abuts. A second arm of the pointer m moves over the scale of the diaphragm adjusting means f. The indicating member may also take the form of a curved or stepped cam disc, and clamping may be dispensed with. The moving coil instrument may be rotatable against an emulsion sensitivity scale. Operation of the diaphragm adjusting ring may move a shutter to limit the effective aperture of the photoelectric cell. The apparatus may be applied to roller-blind and focal plane shutters, and may adjust the shutter-gap. The element determining the shutter setting may be disposed at a distance from the device actuated by the photo-electric cell, and the two may be connected by an antinous member. The Specification as open to inspection under Sect. 91, comprises also apparatus in which the iris diaphragm-adjusting ring is moved by a spring on the release of a detent until an abutment thereon engages the clamped pointer. In copying apparatus the restoration of the diaphragm ring to the initial position and the liberation of the pointer may be effected mechanically or electromechanically through perforations in the film. In kinematographic apparatus the diaphragm setting mechanism is coupled with the control for the filmfeeding mechanism. This subject-matter does not appear in the Specification as accepted.
