Title: Polymeric Colour Developers and their use in Detecting Coupling Compounds
IPC: C12Q1/52
Filed: 1967-05-17
Abstract: 1,164,530. Diagnostic device with polymeric developer. MILES LABORATORIES Inc. 17 May, 1967 [23 June, 1966], No. 22881/67. Heading B1X. [Also in Division C3] Compounds capable of coupling with diazonium salts (e.g. α- or #- naphthol) can be detected in a liquid, which may contain such a coupling compound, by adding to the liquid a water-insoluble polymeric colour developer which contains aromatic diazonium salt groups attached to a cation exchange resin by means of amide linkages (see Division C3), and observing any colour development due to diazo coupling. For test use, the polymeric colour developer can be coated on, or incorporated in, a carrier material, e.g. it can be coated on filter paper to provide sheets containing colourdevelopable zones, or it can be mixed with cellulosic fibres in aqueous medium in order to prepare paper strips or discs containing colour-developing material; also, the polymeric developer can be incorporated into tablets. The colour developer can also be used in the detection of systems, e.g. enzymatic systems, which can be made to liberate coupling compounds, by treatment with a coupling compound precursor substrate, e.g. α- or #- naphthyl phosphate. Thus, in Examples, the developers are used to investigate phosphatase activity in suspect serum or in milk.

Abstract: 185,022. Constantinesco, G. Aug. 31, 1921. Variable-speed gearing rendered automatic by the action of an oscillating mass is specially adapted for use with internal-combustion engines upon locomotives. The mass 12, Fig. 1. is carried at one end of a lever 11, the other end of which may be connected directly to a crank 2 upon the engine shaft 1. An intermediate point on the lever is connected by links 8, 9 to ratchets in opposite phase driving a rotor 10 continuously in one direction. An increased load may result in increased engine speed. In the arrangement shown in Fig. 3, the pendulum lever 5 has a fixed pivot 7 and a second lever 4 is connected to it and to the engine crank 2 and to the ratchet links 8, 9. In a constructional form shown in Fig. 15, the mass is the rim 60 of a fly-wheel oscillating about a fixed pivot 40. The lever 42 pivoted eccentrically at 43 upon the flywheel is connected at one end to the driving- crank 41 and at the other to the ratchetoperating rods 45, 46. One ratchet is shown in section. The rotor 57 is connected by stub links 52, 53 to pads 50, 51, which grip in one direction the inside surface of a drum 47 oscillated by the rod 45. In a further form shown in Fig. 19, the driving connecting-rod 83 oscillates a beam 84 pivoted upon a bell-crank lever 97 carrying the mass 98. The two driven rods 85 act through annular grips 69, 70 applied by rings of skew rods 91, 92. A ratchet grip used in a further form is shown in Fig. 10.

Abstract: 752,611. Magnetic clutches. INTERNATIONAL BUSINESS MACHINES CORPORATION. Aug. 13, 1954 [Aug. 18, 1953], No. 23566/54. Class 35. In a magnetic powder clutch high rate of acceleration and deceleration is obtained by reducing the drag of the clutch members on the iron powder and this is achieved by providing one of the clutch members with a disc rotor having a number of blades separate from one another by slots opening through their peripheral edges, the blade edges being so shaped that the density of the powder is less dense near the blade trailing edges than at the leading edges. The clutch has a disc rotor 48 with radial thin blades 50 (best seen in Fig. 2) extending into a space 29 formed in the field core of the driving outer member A. The blades 50 are separated from one another by inclined slots 60. The Specification describes various shapes and dimensions of these rotor blades the main object of which is to prevent a uniform density of the iron powder in the working gap. Whereas in Fig. 2 the outer ends 61 of the blades 50 are concentric to the rotor axis and thereby forming a constant clearance 63 in another form the blades have the ends eccentric to the rotor axis, but in both cases the thickness of the leading edges 58 of each blade is greater than that of the trailing edges 59 as illustrated in Fig. 4. The field core of the clutch driving member A comprises a number of U-shaped laminations 30 separated into segments by anchors 32 (Fig. 2), and these laminations are so assembled so as to provide a groove to accommodate the field coils 37 part of the radial slot 29 in which the rotor blades rotate. The brake B (Fig. 1) is similarly constructed. Specification 649,553, [Group XXIV], is referred to.

A tractor power lift mechanism in which draft control signals operate, through an upper link 17, Fig. 1 (not shown), and a lever linkage 19, 21 and 25, a main control valve 28 surrounding a shut-off valve 34, is characterized in that the shut-off valve acts on a damping device. In the neutral position shown, the shut-off valve is held in position against its biasing spring by pressure fluid from conduit 4 entering chamber 33 so that the main pump pressure is delivered through a central bore 40 in the shut-off valve to the sump. For lifting the main control valve 28 is moved to the left to connect chamber 33 with an exhaust chamber 47 whereby the shut-off valve is moved by its spring to close the passage to sump. This movement is delayed. by piston 42 on the valve entering chamber 44 from which passage of fluid is throttled at gap 45. Build up of pressure in conduit 48 opens the check valve 49 to conduit 7 and the lifting ram. When the control valve is moved back to the position shown and pressure builds up in chamber 33, suction in chamber 44 also delays operation of the shut-off valve whose movements are therefore damped. For lowering, the control valve is moved to the right and bolt 50 opens valve 53 to connect conduit 7 to the sump. In an embodiment the chambers 33 and 44 are combined but have a throttled outlet and in another embodiment the piston of the shutoff valve throttles the outlet of these chambers.

Ferro-electric compositions of lead titanate, lead zirconate and lead stannate selected from the area ABCD of the phase diagram shown are subjected to a polarizing field of at least 30 kv./cm. at a temperature within the range 50 to 150‹C. Preferred compositions are selected from the area EFGH or from the line HG where no lead stannate is present. The figures indicate percentages by molecular weight. In the composition up to 30% by atomic weight of calcium and/or strontium may be substituted for lead. Examples are given of the polarization of electroded discs composed essentially of lead zirconate and lead zirconate in the molecular ratios of from 54:46 to 51:49. An electrostatic field of 40 kv./cm. is applied for a few seconds at a temperature of 100‹C. The field may be applied until the disc begins to conduct, when it is reversed. Several reversals of the field may be necessary before saturation is reached. The improvement in electromechanical coupling obtained by the invention is explained by a change in crystal structure of the compositions from predominantly tetragonal to predominantly rhombohedral across the phase boundary PB.
