[Class 40 (ii).] Sound-reproducing or like apparatus for converting light variations into " electrical effects," in which selenium or like light-sensitive cells are used, is characterized in that the sensitive surface is divided into several adjacent elements, the electrodes of which are insulated from each other, each element being suitably connected in the circuit of an amplifier. Figs. 1 and 2 show an arrangement for reproducing sound from a film record of the varying-width type. Two cells C<1>, C<2>, placed end on and electrically separated by a very small interval I are arranged transversely to the film so that light transmitted through the record falls on them simultaneously. The cells are connected in a Wheatstone bridge circuit as shown, using two suitable impedances P<1>, P<2>. Connection is made at the points B, D to the grid and filament of an amplifying valve. The point I of separation between the 'cells may or may not coincide with the zero line of demarcation between the opaque and transparent parts of the record. A differential or push-pull connection to the amplifier may be used. The cells may be arranged in diagonally opposite arms of the Wheatstone bridge, and two or more cells connected in series may be arranged in each arm. Fig. 5 shows a further alternative arrangement using several cells Cl, C<2>, C<3> in series. The application of the invention for reproducing from records of constant width and varying opacity is also described.

Title: Process of producing light hydrocarbons by destructive hydrogenation of carbonaceous materials
IPC: C10G1/08
Filed: 1929-06-18
Abstract: 313,963. Fohlen, J. L. June 20, 1928, [Convention date]. Hydrogenation, destructive. - Light hydrocarbons are obtained from natural or industrial carbonaceous materials by simultaneous cracking and treatment with nascent hydrogen under pressures of from 5 to 200 atmospheres and at temperatures from 200‹ C. to 1000‹ C. in the presence of catalysts such as metallic halides. The nascent hydrogen is produced by the decomposition of hydrogen-containing bodies. In an example, shale oil distilling from 200‹ C. upwards is stirred with an aqueous solution of metal halides, iron filings and copper or brass shavings for 4 hours at 300-400‹ C. and 120-180 atmospheres pressure. The product yields 50 per cent of light oil of density 0.850 distilling below 200‹ C. and 42 per cent of oil of density 0.870 distilling between 200‹ C. and 300‹ C. Similar results are obtained by the use of temperatures of 500‹-600‹ and pressures of 20-30 atmospheres. Reference has been directed by the Comptroller to Specifications 275,670, 285,923, 286,678 and 286,680.
