Abstract: 1431872 DC-DC conversion INPEL (PTY) Ltd 7 March 1974 [19 March 1973] 10345/74 Heading H2F A method of obtaining a constant voltage characteristic in a pulse width modulated D.C.- D.C. converter comprises sensing the unsmoothed output voltage, integrating, for each half-cycle, the output voltage with time, terminating the pulse drive to the semiconductor switching devices when the required value of the integral is reached and subtracting the value of the integral obtained during the period of drive circuit delay and storage time after said termination from the integral obtained during the next half cycle. The invention is applicable to a pulse width modulated transistor or thyristor converter (not shown), the voltage in the output windings W1, W2 of which are rectified at D1 ... D4, each half-cycle being integrated by T1 and C1. When the integrated voltage reaches the voltage across C2, which is a function of the desired voltage signal supplied via R4, T2 becomes conductive, and activates a logic circuit 1 which momentarily closes a switch S in the form of a transistor or FET. This action substantially discharges C1. At the same time, a pulse transformer 2 or optical isolator couples a signal to control logic 3 arranged to turn off the output transistors or thyristors of the converter. During the turn-off delay, C1 and T1 continue to integrate the output until the end of the half-cycle, leaving a charge on C1 which is subtracted from the charge due to integration of the next half-cycle so as to minimize the effect of decrease in storage time with increase in load.

Patent GB-1098505-A (GB)
Title: Improved resin coated fabrics and process of making
IPC: D06M15/39
Filed: 1965-03-12
Abstract: A waterproof fabric having improved properties of pliability, crease-resistance and "hand" is produced by applying to at least one face of a textile base having a liquid absorbing capacity a "resin buffering agent" in amount so as to admit an only partial penetration of a resin within the textile base, applying resin in amount to make the textile waterproof such that not less than 6% and not more than 25% of the dry weight of said amount will penetrate into the base, the remaining part of said amount forming a homogeneous film outside and anchored to the base. Textile bases mentioned comprise natural, artificial, and synthetic fibres in suitable blends such as silk, cotton, rayon, cellulose, vinyl or acrylic fibres, polyester, polyamide fibres, e.g. blends of a non-elastic fiber and an elastic fiber, blends of cotton and polyamide fibers, and blends of mineral fibres such as glass fibres.  The "resin buffering agent" may be a liquid non-solvent for the resin e.g. a petroleum distillate such as white spirit which may be impregnated into the base by immersion in a bath of the liquid and the excess thereof eliminated by say a blade or pressing rollers, or directly controlled amounts may be applied. The "resin buffering agent" may be spread only on the side of the fabric to be coated.  Only a part say not more than 65% of the total resin required may be applied in a first step, followed by the steps of setting the resin and then applying the remaining resin in one or more stages.  The resin may be applied as a solution e.g. by spreading with a smoothing blade, as a melt, or as a powder by spraying followed by the application of pressure and heat.  The resin may be an acrylic resin, isocyanate modified polyester which may be used with accelerators, isocyanate modified polyether.  Solvents mentioned are ethyl acetate, butyl and amyl acetate, ethyl and methyl glycol, acetone, methylethyl ketone, methylene chloride, carbon tetrachloride, toluene, mixtures of toluene with methylethyl ketone. The setting of the resin may involve elimination of the solvent or the completion or continuation of polymerization.  The textile base may also be impregnated with a water repellent agent such as a silicon compound say simultaneously with the "resin buffering agent", and a subsequent coating of a silicon compound applied to the side of the base not waterproofed.  In the Example a textile base formed from polyester-cotton blend, or from polyamide yarns is treated. Apparatus for carrying out the process is described.

Patent GB-632386-A (GB)
Title: Improvements in or relating to the production of fuel gas
IPC: C07C1/04
Filed: 1947-04-21
Abstract: Tail gas obtained by reacting CO and H2 and removing normally liquid hydrocarbons and other synthesis products is contacted with a hydrogenating catalyst under hydrogenating conditions for the formation of saturated gaseous hydrocarbons whereby a gas of high heating value and low hydrogen content is obtained.  A further increase in heating value may be obtained by removal of water and carbon dioxide.  Suitable catalysts are iron group metals, e.g. Co or Ni, oxides and sulphides of Group 6 metals, e.g. Cr, Mo and W, and spent catalyst from the synthesis, particularly spent iron catalysts. Hydrogenation temperatures are preferably 650-850 DEG  F. using Fe, Ni or Group 6 catalysts, and 500-750 DEG  F. with Co.  Pressure may be that of the original synthesis, preferably 100-1000 p.s.i. Reaction time is chosen so that substantially all the hydrogen present is consumed. Extraneous hydrogen may be added.  Fluidized catalysts may be used with a particle size from 400 mesh - 1/2 inch diameter-and a linear velocity of the fluidizing gas of 0.1-5 ft./sec. Fluidized operation is preferably used also for the synthesis and for production of the synthesis gas from carbonaceous solids and steam.  Carbon dioxide may be removed from the hydrogenated tail gas by a two-stage scrubbing, for example with monoethanolamine, the scrubbing liquid of the first stage being partly regenerated by flashing, and that of the second stage being regenerated by substantially complete removal of carbon dioxide.  In an example, bituminous coal is converted with steam at 1800-1900 DEG F. and 5-50 p.s.i., the water gas desulphurized and contacted with an iron catalyst at 650 DEG  F. and 325 p.s.i., and the tail gas converted with nickel at 625-675 DEG  F. and 300 p.s.i.
