Title: Mixture of carrier ampholytes and method of preparation thereof
IPC: G01N27/447
Filed: 1965-08-04
Abstract: In a process for separating proteins, such as antigens, antibodies, viruses, hormones and enzymes by iso-electric fractionation the electrolyte used consists of a mixture of polyprotic amino carboxylic acids, each acid containing at least four protolytic groups of which at least one is a carboxylic group and at least one is a basic nitrogen atom.  The constituents of the carrier ampholyte have isoelectric points distributed between pH 3 and pH 11 so as to set up a graded series of pH regions under the action of an electric field the protein mixture fractionating to corresponding pH sites in the gradient.  The carrier ampholyte mixture may be produced by reacting an organic compound containing at least two amino and/or amino groups with a carboxylic acid containing at least one carbon-carbon double bond.  The unsaturated carboxylic acid may be a monocarboxylic acid such as acrylic, methacrylic or crotonic acid or a dicarboxylic acid such as maleic or itaconic.  The nitrogen compound preferably has not more than three C atoms between the N atoms of the amino and/or imino groups. The nitrogen compound may be ethylene diamine, diethylamine triamine, triethylene tetramine or tetraethylene sentamine.

Abstract: 1479182 Inclination measuring instrument ILMEG AB 31 July 1974 [2 Aug 1973 31 Oct 1973] 33873/74 Heading G1F An inclination measuring instrument comprises inclination sensitive means supported by a member mounted on boom which is pivotable about a substantially vertical axis, wherein the inclination sensitive means for simultaneously sensing the inclination of said member in two vertical planes, the inclination sensitive means being rotatably supported on the member. The arrangement is such that the inclination sensitive means may be rotated to a predetermined orientation in any position of the boom. In one embodiment, Fig. 3, the inclination sensing means comprises two pendulum systems, one including a pendulum 12 mounted for rotation with a shaft 10 via a yoke 11 which allows pendulum movement in a plane containing the shaft 10. Tilting of housing 4 about the shaft 10 axis is transmitted via pinions 17, 18 to an inductive transmitter 19, the resultant electrical signal being translated by receiver 20 so as to be presented on indicator 21. The second pendulum system of which only pendulum 12' is shown, is the same as the first except that the pendulum 12' is mounted on a shaft which is disposed at right angles to shaft 10 so as to generate a signal on indicator 22 indicative of tilt in a plane perpendicular to that shown on indicator 21. In a second embodiment, Fig. 4, one pendulum 30 is employed, tilt in a plane at right angles to shaft 31 being sensed as in Fig. 3. Tilt about a second, perpendicular plane is sensed by movement of arcuate bars 32, 33 effected by movement of pendulum 30 substantially parallel to shaft 31. Member 4 may be rotatably mounted on, for example, a drill post 2 by means of journals 23 mounted on a forked bracket 24. Movement of an arm 25 is effected via a Bowden cable by a lever 6 mounted on a second arm 27 preferably the same length as arm 25. After initially setting of the orientation of housing 4, locking of lever 6 automatically maintains the housing orientation during boom 1 movement. Bracket 24 may be rotatably mounted on drill post 2 so as to enable horizontal or upwardly directed drilling. The housing may be filled with damping oil, or each pendulum system separately enclosed in oil filled containers placed in an otherwise empty member 4. Damping of the pendulum movement may be facilitated by electrical, magnetic or mechanical means e.g. a rubber ring 16. The housing 4 may be a paralelepiped, as shown, or cylindrical.

[Also in Group XXXVI] An endless abradant band is made from metal and has a single layer of abradant particles substantially homogeneously embedded in at least an operative portion thereof while the band is being formed by a deposition process. A metal cylinder 20, Fig. 3, externally plated with a layer 21 of base metal and a layer 22 of chromium has applied to it, along part or all of its width, a thin adhesive layer to which abrasive particles 24 are then adhered. A layer 25 of nickel is then deposited until of the desired thickness, and the endless nickel band with the abrasive particles embedded therein stripped from the cylinder. Further abrasive particles may be applied by a gravity method to the cutting edge of the band and more nickel deposited to secure them. In a modification, Fig. 7, a cylindrical former 26 is rotated in a plating bath 32. Abrasive particles suspended in the electrolyte gravitate on to the surface of the former and are embedded in the deposited metal. When this is sufficiently thick the endless band with the abrasive particles embedded therein is stripped from the former. Immersion plating may be used instead of electrolytic plating. A cylinder 36, Fig. 8, may be simultaneously sprayed with abrasive particles from a nozzle 38 and molten metal from a nozzle 40. The sprayed deposit is then stripped from the cylinder.

Classes 83 (ii) and 83 (iv)] Stamping; punching.-Apparatus for forming pipe fittings comprises a die with a cylindrical space to fit around a tubular blank, a second cylindrical space extending laterally therefrom and having at its end an annular wall serving as a gauging abutment and affording a relief opening therein, and oppositely disposed plungers movable longitudinally in the first mentioned space so as to apply pressure to the ends of the blank and to a plastic-filling material within it. The tube 12 to be worked is partially filled with a plastic material 25 and placed in a die formed by the lower and upper members 10, 11 which form a cavity closely surrounding the tube. The lower portion 10 has a lateral passage 15 containing a plug 22 forming a transverse wall 20 with a central opening 21. Plungers 27, 28 having reduced end portions 29, 30 adapted to fit within the tube and determine the thickness of its ends have tapering recesses 35 to serve as relief spaces for the flow of the plastic-filling material. When the plungers are moved together, the tube and the filler are both compressed and are forced into the lateral passage 15, which becomes completely filled. Further pressure serves to punch a piece 40 from the end of the newly formed tube extension by the pressure of the filler acting against the edges of the opening 21, which may be given a slight outward taper. The filler is then removed from the tube by melting and the partially closed end of the branch is sawn off. A preferably solid lubricant such as graphite is provided between the tube and die and between the tube and the filler. Specification 440,601 is referred to.
