Title: Process for the manufacture of polymethine dyestuffs
IPC: C09B23/02
Filed: 1937-05-08
Abstract: 506,720. Dyes. I. G. FARBENINDUSTRIE AKT.-GES. May 8, 1937, No. 13215. Convention date, May 9, 1936. [Classes 2 (iii) and 15 (ii)] Polymethine dyes are made by treating 2- methylene-3-alkyl-, aryl- or aralkylquinoxalines, containing a substituent in the 1-position, or salts thereof, by methods known to be capable of converting heterocyclic nitrogen bases, containing a reactive methylene group in alphaposition to a cyclic-nitrogen atom, into polymethine dyes. The production of the 2-methylenequinoxalines and the formation of the dyestuff may be carried out in one process. Two mols. of the quinoxalines bearing the same or different substituents may be condensed by means of 1 mol. of formaldehyde, orthoformic esters, sodium formate, #-alkoxyacrolein acetates, pyridinium salts, formimino ethers or arylformamidines ; alternatively 1 mol. of the quinoxaline may be condensed with 1 mol. of a cyclic aldehyde, preferably containing auxochromic groups, such as substituted benzaldehydes or indoline aldehydes (cf. Specifications 232,740, 334,706, [both in Class 2 (iii)], 344,409, 351,555, 353,863, and 438,603). Suitable quinoxalines are compounds of the type where x = alkyl, aryl or aralkyl, y=any radicle, e.g, methyl, ethyl, hydroxyalkyl, chloralkyl, sulphoalkyl, aralkyl, acyl or aryl, R =an aromatic ring or ring system wherein the nuclei may be substituted, e.g. by alkyl, alkoxy, halogen, N02, NH2 or S03H. They may be made by condensing N-monosubstituted odiamines with o-diketones or by reaction of 2 3-dimethylquinoxaline with alkyl halides. The dyes yield blue to green shades on cotton mordanted with tannic acid, silk, viscose and acetate artificial silk and act as strong densensitizers for the light sensitive layer of photographic materials. In examples : (1) and (5) N-phenyl- or methyl-2-methylene-3-methylquinoxaline is treated with sodium formate in acetic anhydride; (2), (4), (6)-(9) N-phenyl., methyl-, sulphoethyl- or benzyl-2-methylene-3- methylquinoxaline, N-phenyl-2-methylene- 3 - methyl-6-chlorquinoxaline and N-(p-ethoxyphenyl) - 2 - methylene - 3 - methyl - 6 - aminoquinoxaline are condensed with 1:3: 3-trimethylindoline - 2 - methylene - # - aldehyde in acetic anhydride ; (3) the quinoxaline of (1) is condensed with 4-diethylaminobenzaldehyde; (10) o-aminodiphenylamine is condensed with diacetyl in acetic anhydride and the quinoxaline formed is directly condensed with the aldehyde of (2) ; (11) 2 : 3-dimethylquinoxaline is reacted, with methyl iodide and the 1-methyl-2-methylene-3-methylquinoxaline hydriodide obtained is condensed as in (10).

Title: Automated biuret analysis
IPC: G01N33/02
Filed: 1975-04-01
Abstract: 1459705 Biuret analysis COMMONWEALTH SCIENTIFIC & INDUSTRIAL RESEARCH. ORGANISATION 1 April 1975 [2 April 1974] 13365/75 Heading G1B A single-solution reagent for the colorimetric determination of protein comprises an aqueous biuret reagent (i.e. a reagent comprising potassium sodium tartrate, potassium hydroxide and a source of cupric ions which on contact with protein will give a violet coloration) and an aliphatic alcohol which is miscible with water. The alcohol is preferably isopropanol. Protein in a solution sample may be determined by heating said sample with the single-solution reagent, allowing colour to develop, separatingundissolved matter from the sample and determining the protein concentration by colorimetric measure-  ment. A suitable apparatus for carrying out the determination comprises a heated and stirred reaction vessel, means for dispensing desired volumes of reagent and protein containing material to said reaction vessel, means for dispensing a predetermined volume of sample/reagent mixture from said reaction vessel to means adapted to clarify said mixture and dispense a clarified sample therefrom, wherein the passage of the mixture through the apparatus is controlled automatically. Preferably the apparatus includes means for dispensing reagent to said reaction vessel in an amount determined proportionately to the amount of proteinaceous sample. A suitable form of dispensing means is shown in Fig. 2 and comprises a beam 11 supported on a fulcrum 12, a sample holder 13 and reagent weighing vessel 15 being attached thereto. In operation, valve 19 opens, thus admitting reagent into vessel 15, the beam being consequently depressed until flag 17 interrupts light entering sensor 18, when valve 19 accordingly shuts and valve 20 opens, allowing reagent to syphon out of vessel 15 until flag 17 clears the light ray. The beam lock is engaged and the sample holder is then filled with sample. The lock is then disengaged and the beam falls until flag 17 interrupts the light ray, at which point valve 21- opens and reagent syphons into the reaction vessel until, as the beam rises, the flag clears the light ray and the valve 21 closes. Thus the amount of reagent dispensed to the reaction vessel will be in the same fixed proportion relative to the sample amount.

Filed: 1917-09-18
Abstract: 117,532. Igranic Electric Co., (Cutler. Hammer Manufacturing Co.). Sept. 18, 1917. Resistances.-In a liquid rheostat, stationary semi-pyramidal electrodes are arranged in a circle so that adjacent conductive faces are parallel in horizontal section. Successive rises of the electrolyte produce increasing additions to the active surfaces. Movable electrodes also may be provided, and there may be arrangements for circulating the electrolyte. In the construction shown, each upper electrode 1 forms two sides of an in. verted pyramid, with only its edges presented to wards the tank 3, and is supported by lugs 11 attached to insulated conductors 10 passing through a cover 6. Correspondingly shaped lower electrodes 2 are carried by a spider 13 sliding on a vertical rod 14 and linked to a counterweighted lever 17. The inner tank 3, supported by a flange in an outer tank 4, has a bottom opening controlled by a valve 21 and surrounded by a weir 20, the edge of which is a little above the points of the upper electrodes, to prevent complete opening of the circuit.. Electrolyte is pumped from the outer tank through a pipe 24, and enters the inner tank through a perforated pipe 26 surrounding the weir 20 and covered by a diffusion screen 27 to cause even distribution. When the inner tank is filled, the liquid escapes over its upper edge to the outer tank. For polyphase current, each pair of opposite upper electrodes is connected to one phase conductor by means of a bar 12. The lower electrodes then constitute the neutral point of the resistance and are grounded through their support.

Abstract: 942,445. Rolling. MORGAN CONSTRUCTION CO. June 13, 1960 [April 21, 1959], No. 13592/59. Heading B3M. In a rolling mill having two rolls and an end mounting for each roll at each end thereof, the supporting means for each end mounting include trunnions extending laterally and permitting swivelling movement of the mountings in a plane containing the two rolls. The lower roll 12 is adjustably suspended from the upper roll 10. The chocks 52, 54 of the lower roll are suspended by links 70 from the trunnions 24 of the rollchocks 20, 22 of the upper roll 10. Eccentrics 68 operated by a telescopic screw adjustment through stirrups 86, 94 and levers 88, 96 are provided for adjustment of the roll-gap. The upper roll chock 20 is supported by blocks 32 resting on rollers 36 on bearing ledges 34 of the mill frame 16 so that the chock is slidable within the frame and also capable of swivelling in a vertical plane about the trunnions 24. The upper chock 22 is similarly supported on ledges 42 but instead of using separate supporting blocks eye ends 38 of an adjustable yoke 40 carry the trunnions 28 and bear on rollers 44. The yoke 40 is capable of a limited amount of swivelling in a horizontal plane and is adjustable by a nut 48 and a screw-threaded stem 50 to provide for axial adjustment of the upper roll. The lower roll is independently axially adjustable through a yoke 102 engaging the trunnions of the lower roll which is moved in the axial direction of the roll 12 by the rotation of an eccentric pin 106, the rotation of the pin being by pivoting of a lever 114 fixed to the pin. The chocks are laterally retained by stainless steel plugs 128. For changing the stand the frame 16 is lifted from pedestals 132.
Patent GB-808206-A (GB)
Title: Improvements in fuel injection systems for internal combustion engines
IPC: F02M61/20
Filed: 1955-05-11
Abstract: 808,206. Fuel injection systems. NYLANDS VERKSTED May 11, 1955 [May 11, 1954], No. 13658/55. Class 7(3) A spring-loaded fuel injection valve 4 is opened by fuel from a compressionpressure-operated fuel injection pump supplied through a passage 5 and any increase in the fuel pressure above the normal value required to open the valve 4 opens a spring - loaded needle valve' 25 leading to a pressure accumulator chamber 20, a plunger 18 in which is forced down to increase the spring loading of the valve 4 so that this valve opens later in the compression stroke on the next engine cycle; a bleed 28 permits gradual release of the excess pressure from chamber 20. The plunger 18 is normally held against an adjustable stop 21 by a spring 15 which acts on an abutment rod 13 in contact with the top 8 of the valve 4, which valve is normally loaded by the spring 15 and by a spring 9 in contact with a slidable abutment 10 adjusted by a screw 12. During a normal engine cycle the valve 25 does not open. If abnormal compression pressures in the engine cylinder produce abnormally high fuel pressures in the passage 5 the valve 25 opens and the plunger 18 is forced down to increase the load of the spring 15, whereby a higher fuel pressure is necessary to open the valve 4 on the next cycle and the opening is delayed, producing a lower compression pressure in the engine cylinder and tending to restore the engine compression pressure and hence the fuel pressure back to normal. The pressure in the space 20 is slowly reduced back to normal, permitting the plunger 18 to return to its stop 21, by bleed passage 28 controlled by an adjustable needle 29, which may be manually or automatically adjusted. In a modification the pressure in chamber 20 acts directly on the abutment disc 16 which is sealed to the wall of chamber 20 by a bellows; alternatively the spring 15 may be replaced by a spring-loaded diaphragm closing the chamber 20.

Abstract: 560,832. Testing physical qualities. DENISON & SON, Ltd., S., DENISON, H. M. H., and LENTON, A. Sept. 30, 1942, No. 13707. [Class 106 (ii)] A machine for testing the physical qualities of materials. comprises means for co-ordinating the stresses applied to the specimen with the rate of loading or counterbalancing of a steelyard on which is adjustably mounted a poiseweight, the poiseweight being in part mounted on and traversable along a fixed track disposed substantially parallel to the longitudinal centre line of the steelyard. As shown in Fig. 1, the specimen under test 20 is mounted in a holder 21 and movable anchorage 22. The holder 21 is connected by a lever system 25, 26, 27 and 28 to a steelyard 1. To provide for a constant rate of loading the steelyard is traversed by a trolley 3, Figs. 1 and 3, with a front axle resting on the steelyard and the rear axle movable on fixed rails 10. The trolley supports a poiseweight 5 adjustable along a rate of loading scale 7. A nut on the trolley engages a screwed shaft 14 driven by an electric motor 16. This nut can be readily disengaged by an operating knob 18. A linkage 29 operatively connected to the lever 26 actuates an indicating unit 30 provided with a maximum pointer 31. The anchorage 22 is attached to the ram 23 of an hydraulic pressure cylinder 24. The pressure supply pipe 36 is connected by a branch pipe 37 to a chamber with a piston valve 32, Figs. 1 and 4, connected by a spindle 33 to the steelyard and with an exhaust pipe 35, thereby providing means for controlling the speed of travel of the ram to take up the stretch in, the specimen. Instead of a piston valve a screwdown valve may be employed and the hydraulic system may be replaced by mechanical means such as a screwed spindle driven by a motor, the speed of which is under the control of the steelyard.
