Title: Process for the production of a respiration-stimulating preparation
IPC: A61K35/14
Filed: 1966-07-26
Abstract: The respiration-stimulating activity of the deproteinated blood preparation obtained according to Specification 824,375 is increased by incubating the preparation, in aqueous medium, with human protein. Incubation is performed at 35 to 40 DEG C. for at least 10 and at most 40 minutes, until the dry solids content of the preparation increases from 10-60 mgs./ml. to 40-100 mgs./ml. As human protein, blood preparations such as albumen, serum, haemolysed blood, g -globulin, or preferably Cohn's blood serum fraction IV, may be used. Animal proteins are also disclosed as providing similar enhancement of the activity of the original preparation.  Human proteins are suitably employed in proportions by weight of 3 to 5 parts per one part of the preparation, or even proportions of up to 50:1, based on the weight of the original dry solids content.  The product may be filled into ampoules and sterilised, or lyophilised.

Abstract: 431,900. Valve circuits for wireless reception. MARCONI'S WIRELESS TELEGRAPH CO., Ltd., Electra House, Victoria Embankment, London.-(Assignees of Plebanski, J. ; 32, Wspolna, Warsaw) Nov. 23, 1934, No. 33760. Convention date, Aug. 18. [Class 40 (v)] In a thermionic amplifier of the kind employing one or more tuned rejector circuits connected to auxiliary grids, means are provided for eliminating capacity coupling effects between the auxiliary grid and the input grid. As shown, an auxiliary grid is situated between the input grid and the output anode of a tuned high-frequency valve amplifier and .is connected to a tapping on a circuit L, C tuned to an undesired frequency. One side of the tuned circuit is earthed through a condenser and is connected to a positive voltage source through a resistance R. The other side of the tuned circuit is connected to the input grid through a neutralizing condenser NC. If the rejector circuit L, C is tuned fairly closely at one side of the desired frequency, it produces a sharp fall in the resonance characteristic on that side ; and by employing two rejector circuits tuned respectively on each side of the desired frequency the resonance characteristic falls sharply on both sides. The two rejector circuits may be included in successive stages of a cascade amplifier, Fig. 3, (not shown) ; or they may be connected to separate grids of the same valve, Fig. 5, (not shown). Self-oscillation may be prevented by the use of additional screening-grids and screening-boxes for the circuit elements. Damping of the rejector circuits may be controlled by unbalancing the neutralizing condensers. The amplifier is given a band-pass characteristic by employing coupled output circuits OC.

Title: Improvements in the heat treatment of coal and oil mixtures and distillates obtainedtherefrom
IPC: C10B57/06
Filed: 1934-11-24
Abstract: Coal is mixed with a blend of oils containing low boiling oils, i.e. those having a boiling range below 200 DEG  C., the mixture is subjected to low temperature heat treatment, e.g. at temperatures up to 700 DEG  C., and the middle oils derived from this treatment are converted into low boiling oils in any known manner, e.g. by a catalytic treatment at 150--300 DEG  C. as described in Specifications 445,727 and 445,757.  The blending oil should contain not less than 5 per cent of low boiling oils and the quantity used should be not less than one-third the weight of the coal.  A suitable mixing oil can be derived from the output of the process.  An improved coke is obtained by first grinding the coal with the heavy fractions of the blending oil and then adding the light fractions. 300 grs. coal are ground with 150 grs. of a blend of oils containing one - sixth by weight of a fraction boiling below 200, one - half by weight of a fraction boiling between 200--360 DEG  C., and one-third by weight of an oil boiling over 360 DEG  C.  The mixture is distilled to coke and the distillate, fractionated to separate the fraction boiling between 200 and 360 DEG  C., is treated catalytically as described in Specifications 445,727 and 445,757, e.g. by contact with porous bauxite impregnated with aluminium chloride The gases produced in the treatment are washed to recover vapours by treatment with an oil made up of fractions of specified distillation ranges.

IPC: F15B11/02
Filed: 1967-07-25
Abstract: 1,178,872. Casting-machines. TRANSPORTA, OBOROVY PODNIK. 25 July, 1967, No. 34103/67. Heading B3F. [Also in Division F1] A piston 1 for forcing molten metal into a mould during pressure casting is slidable in a cylinder 2 in response to hydraulic fluid supplied to the cylinder from a line 16, 4, including a valve 11, and when the mould is completely filled the resulting pressure build-up in the line 4 acts on a piston 12 to Close the valve at a speed determined by the adjustment of a throttle valve 10 controlling the rate of discharge from a dashpot cylinder containing a piston 25 which opposes the closing of the valve 11. Hydraulic fluid is supplied to the line 16 by a pump (not shown) and an accumulator 21. When the piston I is to be actuated an electromagnet 18 is energized to cause a slide valve 17 to change-over, whereby liquid flows to the cylinder 2 via the valve 11 at a speed determined by an adjustable throttle valve 22. After the piston I has completed a predetermined part of its stroke an electromagnetic valve 29 is energized whereby a slide valve 28 changes over. The operation of the slide valve 28 causes fluid to open a by-pass valve 23 and an outlet valve 26 in the line 31 from the small area side of the piston 1. Since the by-pass valve 23 is now open the supply to the cylinder by-passes the throttle 22 and flows to the cylinder at an increased rate determined by the maximum opening of the valve 14 which is preset by a screw 15. A simplified arrangement, Fig. 1 (not shown), is also described.

Title: Method of relieving waste liquors from the soda or sulphate pulp manufacture of silica
IPC: D21C11/04
Filed: 1931-12-11
Abstract: In obtaining waste liquors free from silica, when manufacturing cellulose by treating a cellulosic raw material with caustic soda lyes, in the manner claimed in the parent Specification, the hydrooxides or oxides of calcium and/or magnesium, with if desired the hydroxide of aluminium, are employed as precipitants while the alkalinity of the digster liquor is reduced by an amount approximately corresponding to the added quantity of calcium and magnesium oxide and hydroxide.  The process may be used when the caustic soda lye also contains sodium sulphide, sodium sulphite, sodium sulphate, contact substances, phenols, or organic oxyacids or the like.  The presence of organic oxyacids such as are formed when digesting vegetable substances with caustic soda increases the activity of the calcium hydroxide; waste liquor may therefore be added to the digester liquor.  The application of the process to the production of cellulose from wheat or rye straw and esparto grass is described.  The aluminium hydroxide may be used in the form of red bauxite.  The liquor is also freed from carbon dioxide by the process.
