Abstract: 208,313. Western Electric Co., Ltd., (Western Electric Co., Inc.). Oct. 31, 1922. Repeating systems. - In a two-way repeater system in which reflection currents are reduced by means of balancing networks, voice currents in either path operate a relay to open the other path. Fig. 1 shows a two-wire line with four repeater stations having oppositely - directed thermionic repeaters R, connected to the intervening line sections L through hybrid transformers H, each with a network N to balance the corresponding line section L. Fig. 2 shows the second repeater station, in which the junction points of the secondary windings 6, 7, 8, 9 of the transformer 10 are connected to the filament of a valve repeater 16 through resistances 11, 12 and capacities 13 ,14, and one junction point is connected to the grid through a polarizing battery 18. The output circuit is connected through condensers 20 to the primary windings 21 of the transformer 22. A relay 34 is energized by means of a transformer 35 in the input circuit of the repeater 16, thereby opening the output circuit of the oppositely-directed repeater 30 and preventing the flow of currents reflected back at succeeding repeating stations. Reflection currents in the reverse direction are prevented by means of a relay 36 at the third repeater station. The time taken by the reflected currents to reach the contacts of the relays 34, 36 is such that no current passes before the contacts are opened. The invention is also described with reference to a four-wire line.

Title: Improvements in or relating to measuring predetermined quantities by weighing
IPC: G01G13/00
Filed: 1935-11-01
Abstract: 464,868. Automatic - feed weighers. FITZPATRICK, H. J. (Maatschappij van Berkel's Patent Naamlooze Vennootschap) Nov. 1, 1935, No. 30179. [Class 143] Relates to a weighing-apparatus for measuring predetermined quantities of flowable substance and comprising a weighbeam, a supply control valve and a striker for closing same, the striker being adapted, when the predetermined load has been reached, to become unbalanced, and consists in that the striker 17 is pivotally attached to the weighbeam 8 at the fulcrum thereof and, when unbalanced rests on a support separate from the weighbeam so that equilibrium of the latter is not substantially affected by the overbalancing of the striker. As shown in an arrangement for weighing out gases, an empty vessel 11 is placed on the platform 1 and balanced (together with the effect of a flexible pipe 12) by a tare poise 10 and suspended chain 13. A poise weight 15 is adjusted on the weighbeam to the weight of gas required and the valve 20 is opened. When the weight of gas reaches the predetermined load, the weighbeam rises from a support 16, and overbalances the striker 17 which falls on to a detent 25 and permits the valve to close under spring action. The initial position of the striker may be adjusted by means of a screw 19 carried by an upstanding arm on the weighbeam. According to the Provisional Specification the hammer may be pivoted on a downwardly extending arm of the weighbeam, the head of the hammer being more or less at the level of the weighbeam.

Pivoted G-supports 3 and a V-support 33 are also provided. The carriage 8 may, alternatively, be fed by hand, mechanical or combined pneumatic and mechanical means.
Patent GB-303021-A (GB)
Abstract: 303,021. Graesser-Monsanto Chemical Works, Ltd., (Assignees of Curswell, T. S.). Dec. 22, 1927, [Convention date]. Isoeugenol and isochavibetol and derivatives thereof. - The mixture of alkoxyisoeugenol and alkoxyisochavibetol prepared, for example, by heating safrol or isosafrol with alcoholic caustic potash under pressure, is separated by virtue of the difference in the solubilities of their calcium salts, e.g. in alcohol, the calcium salt of the alkoxyisochavibetol being the less soluble. The separated alkoxyisochavibetol may be methylated and then hydrolyzed in order to produce isoeugenol. The latter is also produced from the separated alkoxyisoeugenol by hydrolysis of the alkoxymethoxy group followed by methylation. In an example, safrol is heated with caustic potash and methyl alcohol in as autoclave, and the resulting mixture of methoxyisoeugenol and methoxyisochavibetol, after purification by washing, extraction and distillation, is treated with calcium oxide or hydrate and denatured alcohol or ethyl alcohol. The insoluble calcium salt of methoxyisochavibetol is filtered off, washed with alcohol and acidified to remove the calcium. Before acidifying, the sodium salt may be formed by heating with aqueous soda ash, the resulting calcium carbonate being filtered off. The free methoxyisoeugenol is obtained by distilling off alcohol from the soluble calcium salt solution and acidifying. Isoeugenol is then produced by hydrolyzing the methoxymethoxy group by heating the alcoholic solution with aqueous hydrochloric acid, and methylating by means of dimethylsulphate in the presence of caustic soda. The isoeugenol obtained by acidifying and distillation in vacuo is free from isomers. Isoeugenol is produced from the methoxyisochavibetol by methylating with dimethyl sulphate and then hydrolyzing with dilute hydrochloric acid to remove the methoxymethoxy group. The Specification as open to inspection under Sect. 91 (3) (a) refers to the production of isochavibetol from the separated isomers. This object-matter does not appear in the Specification as accepted.
