Title: An improved method of fermenting and maturing beer and apparatus therefor
IPC: C12C11/00
Filed: 1926-04-26
Abstract: 274,225. Hansena Akt.-Ges., and Nathan, L. April 26, 1926. Fermenting; yeast.-Beer is brewed in a vessel A, the fermentation being carried out in two stages at temperatures 3‹ to 6‹ C. and 10‹ to 25‹ C. respectively. The first stage comprises aerating the wort in the vessel A, supplying about 2 per cent of aerated yeast from a vessel F and fermenting for from 3 to 5 days until only 1 to 1¢ per cent fermentable matter remains, the temperature being controlled by cooling fluid in a jacket K. The fermenting liquor is agitated towards the end of this stage by supplying carbon dioxide through a pipe b and a porous plate D. The carbon dioxide generated during the process is passed out and collected through a pipe e. The yeast is then allowed to settle and is drawn off periodically through a pipe g into the vessel For elsewhere. During settling, the yeast is maintained at 1‹ C. to prevent decomposition by supplying cooling'liquid to a jacket E. The second stage is carried out by the use of the remaining suspended yeast and a certain amount of yeast allowed to remain in the vessel A or supplied thereto from the vessel F. The temperature is raised by warm water supplied to the jacket E, K or by steam supplied through a pipe y, and air is supplied through the pipe b and circulated by a fan X. The yeast in the tank F is aerated through a pipe m and is purified by supplying alkaline liquid and subsequently washing water through a pipe h, the washing liquid being withdrawn through a funnel s. A pipe q supplying compressed carbon dioxide for fineing out the yeast, an inspection and yeast-withdrawal aperture p and a cooling jacket H maintaining the yeast at from 0‹-4‹ C. are also provided. Several tanks such as F each receiving different varieties of yeast may be employed. Warm water is supplied to the jacket E from a portable boiler V having surface steam heating means by a pump W.

Title: Improvements in or relating to the separation of butadiene from olefines
IPC: C07C7/11
Filed: 1942-08-11
Abstract: Butadiene is separated from a C4 fraction containing unsaturated hydrocarbons by contact in an absorption column, at 0-50 DEG  C. and a pressure insufficient to cause liquefaction, with such an amount of an aqueous solution containing a cuprous salt and a hydroxy-alkylamine that, when not less than 93.5 per cent by volume of the butadiene is contained in the solution withdrawn from the column, the vapour pressure of the butadiene over the solution in the base of the column is equal to at least 65 per cent of the operating pressure, part of the gases being disengaged from the solution in the base of the column and used to strip dissolved butenes from the descending solution.  Gas mixtures containing, in addition to butadiene and butenes, other hydrocarbons and inert substances may be treated.  The dissolved butadiene is recovered by the application of heat and/or reduced pressure.  The absorbing solution preferably contains also the hydrochloride of the hydroxy-alkylamine in an amount equal to 1 mol. per atom of copper.  Acetylene must first be removed from gas mixtures to be treated.  If their oxygen content is less than 0.1 per cent by volume, the solution may be retained in its reduced state by the presence of metallic copper or by heating with copper to 15-105 DEG  C.  In an example, a gas 50 per cent each butadiene and butenes is passed at atmospheric temperature and pressure into a packed column at its mid-point, an aqueous solution of cuprous chloride, monoethanolamine and hydrochloric acid being pumped in at the top.  The solution is heated to 45 DEG  C. in the base, and the amount used is such as to give a partial pressure of butadiene of .65 atm.  The solution is removed and heated to 105 DEG C. yielding a gas which is 95 per cent butadiene.  Specification 547,730 is referred to.

Title: Improvements in or relating to electric converter circuits
IPC: H02M5/447
Filed: 1949-04-29
Abstract: 667,684. Converting. PHILIPS ELECTRICAL, Ltd. April 29, 1949 [May 3, 1948], No. 11462/49. Class 38 (ii). An arrangement for converting D.C. into A.C. comprises a plurality of grid-controlled gas discharge tubes 4, 5 at least one of which, say 4, is connected in series with an output impedance constituted by an oscillatory circuit 6 tuned to the frequency of the A.C. to be produced, while the other tube 5, forming an auxiliary tube, is connected in series with a circuit comprising an auxiliary source 8 of alternating current, and a further oscillatory circuit 7 in parallel, the series connected combinations being arranged in parallel and connected to a D.C. source through a common inductance 3, the tubes being ignited in succession according to the frequency of the generated A.C. in which arrangement the auxiliary alternating voltage is chosen to be such that when the auxiliary tube is ignited the other tubes which are in an operative condition are extinguished and vice versa. Voltages 90 degrees displaced from the auxiliary alternating voltage are taken from the brushes 10 and applied to the pulse generator 11 to provide pulses displaced by 180 degrees serving to ignite the tubes 4, 5. When a pulse arrives on the grid of the tube 4 the tube is ignited and an alternating voltage appears in the oscillatory circuit 6. After a period of 180 degrees of this alternating voltage cycle a pulse arrives at the grid of the tube 5, causing ignition thereof and, owing to the auxiliary alternating voltage, the cathode of the tube 5 exhibits a negative potential relative to the cathode of tube 4 whereupon the anode voltage of the tube 4 falls below its operating value and tube 4 extinguishes. After a further 180 degrees another pulse arrives at the grid of tube 4, reigniting it and, again owing to the presence of the auxiliary alternating voltage, the cathode of tube 4 is at a negative potential relative to the cathode of tube 5 so that the latter is extinguished and the cycle repeated. In the embodiment according to Fig. 1 the tuned frequency of the circuits 6, 7 and that of the auxiliary A.C. source must be identical but in an embodiment wherein the series-connected combination 4, 6 comprises a push-pull arrangement the frequency of the auxiliary A.C. source must be double that of the oscillatory circuits 6, 7. The oscillatory circuit 7 materially reduces the reaction of the current through the auxiliary tube 5 on the auxiliary alternating voltage source 8. The brushes 10, 10 may be movable to adjust the phase of the igniting pulses.

In an internal shoe-drum brake having floating shoes with one pair of adjacent ends interconnected by a link 5, and biased towards each other by a pair of springs 6, 6<SP>1</SP>, the brake cylinder 1 is formed with a central partition 8 intermediate two bored sections 9 and 9<SP>1</SP>. The partition 8 is formed with an axial duct 10, connecting with a fluid inlet 11, leading to a suitable pump or master cylinder, not shown. Because of unbalance between the pressures behind each piston 13 or 13<SP>1</SP>, caused by the different reaction forces against the primary and secondary shoes, the duct 10 is closed at its left-hand end by a valve 12. The pressure of liquid compressed in the chambers between the seals 14 and 14<SP>1</SP> acts by way of duct 17<SP>1</SP> upon the piston 13 to displace it an amount different from that of the piston 13<SP>1</SP>. Depending upon the ratio of the diameters of the seals 14<SP>1</SP> and 14<SP>1</SP>a, the displacements thus imparted to pistons 13 and 13<SP>1</SP> will be strictly predetermined, thus providing a convenient manner of matching the characteristics of the resulting brake to any particular application contemplated. If the direction of drum rotation is reversed, the pressure between seals 14 and 14a is communicated to the space to the left of piston 13<SP>1</SP> by duct 17.
