Title: Improvements in or relating to modulating arrangements suitable for use in carrier current signalling systems
IPC: H03C1/20
Filed: 1937-07-30
Abstract: 500,045. Valve modulating circuits. AUTOMATIC TELEPHONE & ELECTRIC CO., Ltd., and TERRONI, T. B. D. July 30, 1937, No. 21208. [Class 40 (v)] The modulating voltage is injected into the anode-cathode circuit of a wave generating or amplifying valve both on the anode and cathode sides of the high-tension source. As shown the modulating-valve PV is a pentode and two of its grids are back-coupled by the circuit LC to produce the carrier wave. Between the anode and the positive side of the H.T. source are connected a resistance R1 and the secondary coil of a transformer T3, and a further resistance, R2 and transformer T2 are connected between the cathode and the negative HT terminal. The primary coils of transformers T2, T3 are in series in the plate circuit of a valve TV, the grid of which is fed from the source of modulation M. The outer ends of resistances R1, R2 are connected by a carrier byepass condenser C3, whilst their inner ends are connected by condensers C1, C2 to the output terminals, which may be used to feed a push-pull amplifier for the modulated wave. The pentode may be replaced by a screen-grid valve, and the carrier may be generated by a separate valve and fed to a control grid of the modulating-valve.

Patent GB-359024-A (GB)
Title: An improved process and apparatus for hydrogenating hydrocarbons
IPC: C10G69/00
Filed: 1930-07-15
Abstract: Hydrocarbon oils are admitted, preheated if desired, through line 6 to a still 160 at atmospheric pressure or above, the oil vapours pass through lines 163, 35 to a vaporizer 7, the residue from the still is circulated through cracking and hydrogenating zones such as coils 25, 26, 27 with or without conversion chambers 30, 32 and with or without catalysts, the whole of the products from the hydrogenating zone are discharged into the vaporizer through lines 98, preferably in intimate admixture with the distillation vapours, vapours are withdrawn at 55 and worked up for gasoline and other light fractions, and residue is withdrawn from the vaporizer at 43.  Molybdenum and tungsten catalysts are mentioned.  The oil entering the still 160 preferably spreads over an inclined tray 161.  Live steam may be introduced at 162.  The hydrogenation gases are the same as described in Specification 359,023, and the apparatus is similar to that shown in Figs. 1 and 2 of that Specification with the modifications concerned with distilling the hydrocarbons at 160 instead of introducing them into the vaporizer.  The hydrocarbons are treated in the coils at temperatures usually between 750 DEG  and 1200 DEG  F. and under pressures of 50 to 200 atmospheres or more. The pressure in the conversion chambers may be lower than in the coils.  The temperature in the conversion chambers may be regulated by re-circulating cooled oil from other parts of the system such as intermediate condensate and residue from the vaporizer 7, and the temperature is maintained preferably above 700 DEG  F.  When the conversion chambers are dispensed with, the hydrocarbons may be treated in the coils at temperatures between 750 DEG  and 1500 DEG F. and under pressures <PICT:0359024/III/1> of 50 to 300 atmospheres or more, and the pressure in the vaporizer may be atmospheric, or 5 atmospheres or more and the products may be cooled as they leave the coils by recirculating intermediate condensate from the vaporizer. The intermediate condensate from the vaporizer may be withdrawn at 119, 171 or it may be recirculated through lines 170, 45, 12, 37, and branches including a branch (not shown) leading to the stream of products entering the vaporizer.  The intermediate condensate may first be treated in a still 66 for removal of lighter fractions before it is recirculated.  The coil section 27 may be by-passed. The residue from the vaporizer may be removed at 71 or returned to the hydrogenating zone through lines 45, 22 and branches, or it may be treated in stills 74, 75 and the final residue withdrawn or returned to the hydrogenating zone through lines 113, 22.  The treatment in stills 74, 75 may be carried to dryness.  The vapours withdrawn from the vaporizer at 55, and from the stills 66, 74, 75 are worked up as described in Specification 359,022, and the uncondensed gases and vapours are treated and recirculated as described in Specification 359,026.  Specification 328,997, [Class 32, Distilling &c.], also is referred to.

Title: Improved phenolic resin adhesive
IPC: C08G8/04
Filed: 1945-08-22
Abstract: A water soluble thermosetting phenolic resin adhesive for plywood is obtained by initially reacting a phenol having a distillation range between 180 DEG  and 220 DEG  C. and containing not more than about 15 per cent of orthocresol, xylenol, or a mixture thereof with formaldehyde which contains methanol and caustic soda in the range of substantially between 2.25 and 3.50 molecules of formaldehyde per molecule of phenol and caustic soda in the range between substantially 14 per cent ( 1/7 th) and 7 per cent ( 1/15 th) of a molecule per molecule of formaldehyde, and subsequent to the initial reaction, treating the product with additional caustic soda, bringing the total caustic content into the range between about 0.3 and 1.0 molecule per molecule of phenol, at which said adhesive becomes resistant to thinning upon further treatment with caustic soda. Ammonia may be added to the condensation product in an amount sufficient to eliminate the odour of formaldehyde but not sufficient to leave an ammoniacal odour, thereby increasing the storage life. Formalin containing 10 per cent methanol is used in Examples I, II, and III, and formalin containing 7.5 per cent methanol in the remainder of the following examples in which (1) 1 mol. phenol, 3 mols. formalin and 0.2 mols. NaOH are refluxed, cooled to room temperature, and then water, 0.4 mols. NaOH, and ammonia are added; (II) as in I, but the NaOH is employed in two portions of 0.3 mols. each, the second portion being added to the reaction mixture at 68 DEG  C.; (III) 1 mol. phenol, 2.25 mols. formalin, and 0.15 mols. NaOH are refluxed, and 0.45 mols. NaOH water, and ammonium added to the mixture at 68 DEG  C.; (IV) 1 mol. metacresol, 3 mols. formalin, ethanol, and 0.3 mols. NaOH are refluxed, and 0.56 mols. NaOH then added at 66 DEG  C.; (V) 1.0 mols. phenol, 3.0 mols formalin, 0.3 mols. NaOH, and methanol are refluxed, and 0.4 mols. NaOH ammonia, and water then added; (VII) 1 mol. phenol and 3 mols. formalin are refluxed with H2SO4 at pH1.1, and 0.017, 0.3, and 0.4 mols., NaOH added in stages, refluxing after each addition. Fillers specified are wood flour, walnut shell flour, and China clay.  The products may be spray dried.  Specification 585,577 is referred to.
