Title: Improvements in loud-speaking telephone arrangements
IPC: H04M9/08
Filed: 1947-08-08
Abstract: 597,170. Circuits for loud-speakers. PHILIPS ELECTRICAL, Ltd. (formerly PHILIPS LAMPS, Ltd.), and LATIMER, K. E. March 29, 1945, No. 8031. [Class 40 (iv)] In a loud-speaking telephone system of the kind in which the loud-speakers also serve as microphones, the apparatus at a substation comprises two loud-speakers associated with a hybrid coil or the like so that the impedance of each loud-speaker balances that of the other, and the loud-speakers are fed effectively in phase by currents from the exchange line, while currents due to sounds picked up by the loudspeakers when acting as microphones are fed to the exchange line. As shown in Fig. 1, the two loud-speakers LS1, LS2 are fed in phase by currents from L2 and transmit over L1 in phase opposition. Arrangements such as are indicated in Fig. 2 are provided to switch the loud-speakers for reception or transmission with maximum efficiency. In the condition shown, incoming signals from the exchange line are fed via A2 and relay contacts R2 to L2 and operate both loud-speakers in phase, while the poor quality output from the loud-speakers is fed via R1 and A1 to the exchange line. Relays R1, R2 (not shown) operate as follows : Speech picked up by the loud-speakers first operates R2 connecting L1, L2 in parallel to A1, R1 then follows connecting L1 to A2 so that good quality transmission is effected via L2 and a poor quality path exists over L1 for receiption. Incoming signals will operate R2 and R1 in a similar manner to restore the original conditions. Detectors AD1, AD2 control the operation of differential relay DR and thence R1 and R2 in accordance with the conditions obtaining at the substation.

Title: Method of and apparatus for refining or treating hydrocarbon or mineral oil
IPC: C10G21/16
Filed: 1935-03-15
Abstract: <PICT:0445317/III/1> Hydrocarbon oils especially lubricating-oil distillates are freed from naphthenic constituents of low viscosity index by treatment with furfurol flowing in counter-current with the oil through one or more extraction zones, and maintaining a graduated range of temperature in the zones of about 100 DEG  F., between the refined oil discharge and the extract discharge (at the lower temperature). Lubricating oil distillate at a temperature of 80 DEG F., or lower flows through a pipe 19 to a distributing head 20 mounted at the lower end of a vertical extraction tower 17.  Packing material 18 consisting of Raschig rings, or tile is provided in nests, or alternatively screens, baffles or bubble trays may be used. Furfurol at 250 DEG  to 300 DEG  F., passes through a pipe 21 and distributing head 22 and flows downwards through the upwardly flowing oil.  The refined oil is discharged through a pipe 23 and the extract through a pipe 24.  The extract is drawn off at the lower temperature at which furfurol has substantially no solvent action on the paraffinic constituents.  Another form of apparatus consists of a series of three mixers and accompanying settling chambers through which the oil and furfurol flow in opposite directions.  The settling chambers are maintained at 150 DEG , 180 DEG  and 225 DEG  F. Furfurol may be diluted with benzol, toluol or light petroleum hydrocarbons such as propane, butane or pentane. Wax-containing oils, kerosene or naphtha may also be treated.

March 13, 1930, No. 8186. [Class 39 (i).] In making indirectly heated cathodes of small cross section and comprising a metal tube enclosing a refractory metal heating filament covered by a thin refractory insulating tube, the filament is assembled in the insulating tube and the tube is then straightened sufficiently to introduce it into the metal tube. In making the insulating tube, a core of silk thread of larger diameter than the filament is coated with a paste containing porcelain and heated to sinter the porcelain and remove the thread by oxidization. The core may be of aluminium removed by vaporization on heating in vacuo, any aluminium oxidized combining with the porcelain. The coating may be applied by drawing a long thread over wheels rotating in the paste. Fused bauxite, with kaolin as a binder, may be used instead of porcelain, or magnesia, with an agglomerant of starch, dextrin, tar sugar, or gum tragacanth, may be moulded or extruded about the core, or the insulating coating may be sprayed on the core. The heating filament is introduced into the resulting tube and the tube is straightened by heating to the softening point and tensioning the filament. Each leg of a hairpin heater is surrounded by a separate tube.
