Abstract: 1,254,619. Matching impedances. AMP Inc. 22 Dec., 1969, No. 62261/69. Heading H1W. [Also in Division H2] A coaxial connector for a high frequency transmission line has contacts adapted to compensate for impedance variations due to tolerances in the connector. In Fig. 5 the increase in impedance due to the gap S is compensated by the decrease in impedance produced by the increase in diameter of the front resilient fingers 50 of inner contact 44.   Similarly, in Fig. 8 the compensation for an increased impedance is effected by the decrease in diameter of the resilient portions 74 of outer contact 70.

Patent GB-733760-A (GB)
Abstract: 733,760. Floors; stair treads. BETTLES, J. W. E. Dec. 14, 1953 [Oct. 22, 1953], No. 29138/53. Class 20 (4). [Also in Group XIV] Open metal flooring, stair treads, or metal reinforcement fabric comprises parallel main bars 1, Fig. 1, connected by U-shaped crossbars 3 which are engaged in correspondingly shaped notches 2, Fig. 1, in the tops of the bars 1, the tops of the cross bars being level with those of the main bars, and the cross-bars 3 are held against longitudinal movement such as by swaging their side edges. The side limbs 4 of the bars 3 have parallel portions and outwardly splayed bottom portions, the notches 2 being correspondingly shaped. After slidably engaging bars 3 in the notches, the backs 5 of the cross-bars lying level with the tops of bars 1, the side limbs of bars 3 are swaged either upwardly at 6, Fig. 3, or downwardly for the full span between the main bars. Nozing bars 8 may be secured to the ends of the bars 1 by welding, riveting or tongue and groove engagement.

On subsequently pressing the cross-bars level with the main bars, surplus metal at the bottom of the side limbs of the channel bars is swaged upwardly between the main bars. In a further form the side limbs of the cross-bars are shaped to slide into the notches from the top and afterwards are splayed outwardly at the bottom during the swaging operation.

Patent GB-789372-A (GB)
Abstract: 789,372. Frequency phase measurement. METROPOLITAN-VICKERS ELECTRICAL CO., Ltd. Feb. 2, 1955 [Feb. 12, 1954], No. 4275/54. Class 37. A polyphase A.C. supply is tested for frequency and for phase angle in comparison with another similar polyphase supply by connecting the first supply to corresponding phase ends of a polyphase winding producing a rotating magnetic field, connecting the other polyphase supply to the remaining phase ends of the polyphase winding so as to produce a notional counter rotating field, and determining the angular position or velocity of angular displacement of the axis of the resultant field. The single polyphase winding responsive to both A.C. supplies may be replaced by two separate polyphase windings responsive one to each A.C. supply to produce two opposed rotating magnetic fields. Each polyphase winding may comprise a separate coil for each phase, or a single winding tapped to give individual phase sections. The rotation or position of the resultant field axis is indicated by a laminated salient pole rotor pivoted in the field, which may be unwound, or carry a closed coil winding, or be wound with a coil energized through a capacitance substantially in the same phase as the resultant stator excitation; so that the rotor axis aligns itself with the resultant field of the stator, which sets itself along a line representing the phase difference between the polyphase supplies referred to a fixed axis, or rotates at half the angular frequency of the frequency difference. The resultant field may be derived from similarly energized and disposed pairs of deflection coils of a cathode-ray tube whose screen exhibits a diametrical straight line positioned or rotating similarly to the rotor axis. Alternatively, the polyphase voltages may be applied to an equivalent arrangement of electrode plates producing a resultant electrostatic field, either stationary with axis denoting the phase angle between the two supplies or rotating at half the angular frequency difference, which may be indicated by the deflection of a cathode-ray tube or of an electrode pivoted in the field. The device is applicable to the measurement or comparison of phase angle to phase responsive remote control systems or to indication of differential speeds in response to the outputs of A.C. tachometers.

Patent GB-2014740-A (GB)
Title: Electromagnetic flowmeters
IPC: G01F1/58
Filed: 1979-02-20
Abstract: An apparatus for measuring the volume of a liquid per unit time flowing through a tube comprises a tube member of diameter D, the axis of which is considered to lie along a z- axis of a right-handed coordinate system. The tube member is insulated at least in the interior thereof and a pair of electrodes E1, E2 is arranged diametrically (defining the x-axis) and connected to a voltmeter. A magnetic field substantially perpendicular to the x-z plane is provided whereby variations in the flow rate of fluid through the tube member cause corresponding variations in the measured voltage. The magnetic field is selected, e.g. by using two pairs of pole shoes or coils on respective sides of the electrode (x, y) plane, such that the y- component of the field descends from a saddle point (xs, ys, zs) in both directions parallel to the x-axis and rises in both directions parallel to the z-axis and descends after exceeding a maximum, where ¦xs¦<0.1 D, ¦ys¦<0.45D, and ¦zs¦<0.1D. The resulting measurement is thereby less dependent on the rotational flow state of the fluid. <IMAGE>

Patent GB-2026996-A (GB)
Title: Monocalcium Phosphate and Phosphoric Acid Production
IPC: C01F11/22
Filed: 1979-05-17
Abstract: Monocalcium phosphate, phosphoric acid and/or potassium phosphate containing fertilizers are produced in a process involving acidulation of phosphate rock with phosphoric acid in the presence of added silicon dioxide and potassium ion whereby fluorides contained in the rock are converted to K2SiF6 and monocalcium phosphate dissolved in phosphoric acid is formed during acidulation. In an important feature, the K2SiF6 is separated and hydrolyzed to regenerate the K2O from K2SiF6 recycled KH2PO4/H3PO4 solution for further reaction with fluoride from fresh phosphate rock feed. A portion of the MCP/H3PO4 solution and/or crystallized monocalcium phosphate can then be reacted with potassium sulphate, potassium bisulphate, or mixtures thereof to form KH2PO4, or KH2PO4/H3PO4, solutions, and gypsum. In a closely related embodiment, the remaining MCP/H3PO4 solution is reacted with sulphuric acid to produce phosphoric acid product and/or the recycle phosphoric acid required in the phosphate rock acidulation step.
