Patent GB-113571-A (GB)
IPC: C05F11/00
Abstract: 113,571. Richards, E. H. Aug. 24, 1917. Manures.-To produce manure, straw or other material containing fermentable carbohydrate is submitted to aerobic fermentation such as will break up the carbohydrates and form from them nitrogenous substances by fixation of atmospheric nitrogen, for example by inoculation with a mixture of B. lactis aerogenes and B. azotobacter, and is subsequently subjected to anaerobic fermentation to render the nitrogen available manurially, for example by inoculation with sewage or liquid manure. The inoculating solution for the aerobic fermentation may be prepared by inoculating a starch-phosphate medium with soil, incubating for about fourteen days at 25‹ C., and diluting the culture thus obtained with water. The aerobic fermentation is carried out by placing the moist straw &c., chopped or whole, in a cylinder A, Fig. 1, of wire-netting which dips into a trough D containing the inoculating solution, chalk or other acid-neutralizing agent being added to the straw and to the inoculating solution. The cylinder is occasionally rotated half a turn to keep the contents evenly moistened. Means may be provided to maintain the material at about 25‹ C. The fermented straw, mixed with excess of water, is then subjected to anaerobic fermentation by inoculating with sewage or liquid manure in a tank E, Fig. 2, having a conical sump E<1> provided with a coil G to keep the temperature at 25‹ C. to 30‹ C. An endless spike lift F may be provided to discharge the manure. The excess of liquid from the second fermentation may be absorbed by comparatively dry material from the first fermentation and used directly as a fertilizer.

Title: Improvements in the production of aliphatic alcohols and esters
IPC: C07C29/00
Filed: 1932-04-21
Abstract: Aliphatic alcohols and (or) organic esters thereof are prepared by subjecting hydrocarbons to thermal decomposition in the presence of the vapour of an organic acid, preferably a lower aliphatic acid such as acetic or propionic acid, and in the presence or absence of steam. Suitable hydrocarbons are petroleum or petroleum fractions, ethane, and propane.  The reaction may be effected at 500--1000 DEG  C., preferably in the gaseous phase at about atmospheric pressure, in the presence or absence of dehydrogenating catalysts and (or) inert gases such as nitrogen and oxides of carbon.  The products are preferably kept at 200--600 DEG  C. and 20--100 atm. pressure before they are finally cooled, a further quantity of acid vapour, with or without steam, being added if desired before or during this treatment.  The reaction or the after-treatment of the reaction products may be performed in the presence of hydration or esterification catalysts such as phosphoric acid or zinc chloride; fillers such as pumice or kieselguhr may also be present.  Details are given of the relative proportions of acid vapour and steam to be employed according to whether alcohols or esters are desired as principal products.  If mixtures of esters and alcohols are obtained, they may be converted into esters or alcohols by esterification or saponification.  In the example, a mixture of a vaporized petroleum fraction and acetic acid vapour is passed through narrow tubes at 700 DEG  C. and atmospheric pressure, and the products are passed at 400 DEG  C. and 40 atm. pressure through tubes containing phosphoric acid on pumice; the products include ethyl acetate. Specification 394,376 is referred to.

Title: Electrolytic recovery of metals from solution
IPC: C25C7/02
Filed: 1970-03-11
Abstract: 1312681 Electrolytic recovery of metals from solution PPG INDUSTRIES Inc 11 March 1970 [11 March 1969 2 June 1969] 11559/70 Heading C7B A method of recovering metal from a first solution containing trace amounts of the metal as ions comprises (a) subjecting the first solution to electrolysis in an electrolytic cell while passing the solution through a porous cathode of the cell to deposit out metal in the cathode, (b) reversing the potential and having a second solution in the cell resulting in resolution of the metal, the metal being in a more concentrated form in the second solution than in the first, and (c) recovering the metal in metallic form from the second solution by electrolytic deposition on to a cathode. The first and second solutions may be aqueous alkaline, acid or salt solutions (e.g. of NaOH, HCl or Na Cl). Specified metals to be recovered are Hg, Cu, Fe, Ni, Pb, V, Mn, Ru, Rh, Pd, Os, Ir, Pt, Au and Ag. Where different metals are to be selectively removed from the first solution this may be done by passing the solution through a series of cells each having a cathode at a different potential. Where more than one metal has been deposited in the porous cathode the electrode potential during removal of the metal can be controlled to selectively remove particular metals. The porous cathode may be of carbon, e.g. graphite, or sintered or sponge metal, such as sponge Ti or Zr having Pt group metal in the interstices thereof. The anode may be carbon, e.g. graphite, Ni, Pt group metal or Ti coated either with Pt group metal or with an oxide or oxides thereof. The electrolytic cell may comprise a cylindrical body 11 with an anode 13 and porous cathode 12. Solutions may be passed through the cell in either direction between openings 21, 22. Vents 25, 26 are for removal of product gases. Fig. 3 (not shown) illustrates a cell comprising an anode (113) within a blind-end tubular porous cathode (112) within a cylindrical container with solution flow through the wall of the porous tubular cathode between openings (121, 122). The second solution may be passed through the cell one or more times to dissolve the metal deposited in the cathode. The second solution may be different from the first. As illustrated in Fig.1, the method is employed in removing Hg and other metallic impurities from brine which has passed through a Hg cathode electrolytic cell. The metallic impurities are removed in a porous cathode cell and the brine is then electrolyzed in a diaphragm cell. The metallic deposits which build up in the porous cathode can be redissolved by (i) reversing the current and passing therethrough brine containing substantial amounts of free Cl 2 which removes the Hg but not all the Fe and (ii) thereafter removing the remaining Fe by circulating acid, e.g. HCl, through the cell under either normal or reversed potential. Reference is made to what is claimed in Specification 1312682. Reference has been directed by the Comptroller to Specification 1169206.

[Also in Division A2] A tray of plastics material such as polystyrene for meat &c. has in the base and/or sides a multiplicity of capillary recesses capable of holding liquids out of contact with the meat &c. The tray or container is of dished form and of rectangular shape, the top of the walls being outwardly disposed to form flanges 1 with an inverted groove 2 between them. Each wall contains a number of hollow ribs 3 of substantially semicircular cross-section, each rib merging at its upper end into the corresponding wall whilst the opposite end merges into the base of the tray at a predetermined distance from the juncture of the wall with the base. The multiplicity of capillary recesses 4 formed in the base comprise substantially hemispherical depressions whose upper ends are slightly rounded to provide a honeycomb patterned series of boundary walls 5 which form a multiplicity of peaks 6. These peaks minimize the area of contact of the tray with its contents and allow air circulation. The capillary recesses 4 retain any liquids which separate from the contents, even when the tray is inverted. Other embodiments (not shown) may contain moulded partitions which may or may not themselves contain capillary recesses, or may be made of laminated plastics. In a further embodiment a small percentage of the cavities may be opened towards their base, which will allow'liquid exceeding the height of the capillary to escape. Such trays can be used for horizontal purposes.

Class 37 A high frequency voltage of e.g. 10 mc/s is fed to the base of a transistor 1 (Fig. 1) whose cut-off frequency is to be tested over resistance 5 together with. a pulsed voltage of period, e.g. 40 micro-seconds applied over a network 6 distorting it to an approximately saw tooth wave-form. The emitter is earthed and the collector is connected through a resistance capacitance low pass filter 7, 8, 9 to a transistor amplifier 10 energizing the X plates of a cathode ray oscillograph with the varying current. The collector is also connected over resistance 13 to an oscillatory circuit 12 tuned to the high frequency to derive a corresponding voltage proportional to the transistor collector current, which is applied to the Y plates to produce a trace (Fig. 2) wherein the short circuit current amplification a 1 is displayed as a function of bias current. It is shown that the cut off frequency Wg=a<SP>1</SP>W where W is the energization frequency e.g. 10 mc/s, so that effectively the cut off frequency Wg is displayed as a function of the bias current. For calibration the transistor is replaced by a capacitor in its base collector circuit, which is equivalent to a transistor in which a <SP>1</SP> = 1, so that the oscillograph is deflected vertically to a position corresponding to cut off at the high frequency of e.g. 10 mc/s, and a calibrated oscillograph applied to the junction of resistances 7, 13 indicates a voltage proportional to the bias current.
