Title: Improvements in blood coagulation mediums and process of manufacture thereof
Filed: 1921-05-06
Abstract: A blood-coagulating substance is prepared from lung tissue by making an extract of the tissue in dilute salt solution and precipitating the active substance by making the solution very slightly acid.  The substance is stated to be a globulin and to consist of a combination of a protein and a phospho-lipin.  In a modified process a preparation is obtained by making an extract of lung tissue in dilute salt solution, separating undissolved matter by centrifuging, and adding more phospho-lipin.  A small amount of caustic soda may be added to the final solution to prevent subsequent precipitation of fat.  A known preparation consisting of an extract of brain tissue in salt solution is referred to.  The Specification as open to inspection under Sect. 91 (3) (a) refers also to extracts from kidney and other tissues, and to the addition of further phospho-lipin by grinding the solution of lung extract with fat extracted from brain-tissue by means of a volatile solvent.

Title: New intermediate products for the phthalocyanine synthesis
Inventor: BAUMANN FRITZ
IPC: C07D209/50
Filed: 1949-08-25
Abstract: The invention comprises compounds of the formula <FORM:0698070/IV (b)/1> where A is an o-arylene radical (substituted or not) and R is an alkyl, hydroxyalkyl or alkoxyalkyl radical of 1-6 carbon atoms or a cycloalkyl radical.  These are made by reacting o-arylene dinitriles with alkali alcoholates or substances reacting as such, in an alcohol or mixture therewith with other solvents; the crystalline products, often containing one extra molecule of alcohol, precipitate during the reaction or after cooling. Preferably one mol. or more of alcoholate is used per mol. of dinitrile.  Liquid ammonia is a suitable solvent for mixture with the alcohol.  The presence of water leads to the formation of imino-dicarboxylic acid imides.  The products of the invention, in the free state or as their alkali salts, are intermediates for amino-imino-isoindolenines (see Specification 698,049), dehydro-phthalocyanines and phthalocyanines (see Specification 698,039).  In the examples phthalonitrile is reacted with methanol, ethanol, isopropanol and ethylene glycol to give products where A is a benzene nucleus and R is methyl, ethyl, isopropyl and b -hydroxyethyl respectively.  Other suitable alcohols are n-propanol, n- and iso-butanol, hexanol, cyclohexanol, propylene and butylene glycols and glycerol.  The phthalonitrile may be substituted by halogen, methyl, t-butyl, phenyl, alkoxy, phenoxy, alkylthio, arylthio or sulphonic acid groups.  2 : 3-Dicyanonaphthalene and 2 : 3-dicyanopyridine are also suitable and in general all dinitriles known to be used for the preparation of phthalocyanines.

Title: Improvements in or relating to alternating current measuring apparatus
IPC: G01R15/00
Filed: 1931-05-07
Abstract: 373,762. Thermionic valve circuits. SMITH, C. H., 29, Mount Park, Carshalton, Surrey. May 7, 1931, No. 13555. [Class 40 (v).] Apparatus for measuring alternating currents or voltages or for comparing two currents or voltages is so arranged that the degree of response of the indicating means is proportional to the logarithm of the quantity being measured. As shown in Fig. 2, signal voltages to be measured are applied through a transformer 1, triode 2, and transformer 3 to a diode rectifier 4 in series with a direct-current measuring instrument 5. The filament current of the diode 4 is adjusted to a smaller value than usual, so that the working voltages are in the neighbourhood of the upper bend of the characteristic curve and the valve normally operates near the saturation point. Under these conditions the rectified current is substantially proportional to the logarithm of the voltage applied to the input terminals. In the modification shown in Fig. 3, two pentodes 6 are connected in push-pull relationship and arranged to work as diodes. The control and space-charge grids of the pentodes are connected to the negative terminal, the screening grid being connected to a point on a potentiometer 7 connected across the source of hightension supply, or alternatively through a variable resistance to a point on the hightension source. The apparatus may be connected between a microphone and a wireless transmitter, or at some point in a wireless receiving set, and gives a response which is proportional to the aural intensity of the sound. A milliammeter with very light moving parts and critical damping may be employed as the indicating instrument 5. For measuring directly the difference in decibels between two signals, two instruments as shown in Figs. 2 or 3, may have their output circuits connected in opposition so that the milliammeter indicates the difference of the output currents and therefore the ratio of the input voltages. An amplifying valve may be inserted before the milliammeter. This arrangement may be employed for comparing two microphones, of which one is calibrated.

Abstract: 1,048,436. Automatic arc furnace control. ALLEGHENY LUDLUM STEEL CORPORATION. April 2, 1964 [April 2, 1963], No. 13743/64. Heading G3R. In an automatic arc furnace control system wherein the arc length is controlled by arc voltage, within defined high and low limits arc voltage or current transients below 30 cps are utilized to control the arc length which transients increase in frequency as the arc shortens. The arc length may be controlled according to the frequency of the transients, or they may be integrated over a period of time. Alternatively transient amplitude may be the criteria of operation. The arc voltage is sensed by high and low voltage circuits 46 comprising magnetic amplifiers and if inside these limits the arc control is switched by a relay 88, 90, 92 to transient control comprising a filter 58 to eliminate d.c. ripple and a timing control counter 84. If the count is less than a first given amount in a predetermined period the arc length is shortened by a fixed amount successively until the count increases. If the count reaches a second given amount the arc voltage will be lengthened until stopped by the high voltage circuit 46.

IPC: F41B11/642
Filed: 1920-05-19
Abstract: 143,548. Beck, H. Nov. 5, 1917, [Convention date]. Projectors and projectiles.-Relates to pop-guns of the type which throw missiles prepared by the gun itself from flat pieces of soft material such as slices of apple or potato or orange-peel. The strip 4, Fig. 1, of material is placed in a holder 3, and the ejector rod 2 slides within a guide-sleeve 3<a> in alinement with the barrel 1. Thus, if the ejector rod is pushed forward, it will punch a piece out of the material and push it forwards in the barrel towards a similar missile, which is ejected by the air compressed between the two missiles. In order to ensure that the missile shall fit tightly, the barrel may have its bore of larger diameter at the rear, so that the missile is compressed as it is moved forwards. The barrel may also be made to slide in the holder 3, so that when it is pushed backwards into the holder, it will cut out a missile from the strip 4. Alternatively, the rod 2 may slide through a sleeve which can be forced into the holder 3 towards the barrel, in order to cut out the missile. In another modification, instead of using a missile to compress the air, a piston is used which may be actuated bv the rod 2 or by a spring. The toy may be made in the form of a quick-firing gun, Fig. 10, having elevating and traversing arrangements. The barrel is moved backwards to punch out a missile by retracting the ejector rod 2. Any suitable device may be used for feeding the material 4 through the holder.
