Title: Improvements in or relating to pressure responsive devices
IPC: G01L13/02
Filed: 1954-01-04
Abstract: 774,795. Pressure measuring and controlling devices. GEHRE, H. Jan. 4, 1954 [Jan. 2, 1953], No. 185/54. Class 106 (2). [Also in Group XXIX]  A pressure responsive device for instruments for measuring, transmitting or controlling the pressure of a fluid flowing through a pipeline, comprises a plurality of spaced bellows positioned axially in series, in which only the front surface of the first bellows is in presusre connection contact with the service pressure of the fluid in the pipeline and only the rear surface of the last bellows is in pressure connection contact with a counterpressure determining the overall pressure difference existing between the front surface of the first bellows and the rear surface of the last bellows and in which are provided arrangements, other than direct connection to the atmosphere, for creating in the space or spaces between the bellows such a pressure or pressures as form with the service pressure and the counterpressure a gradated series, preferably such that the sum of the effective pressure differences at the individual bellows is approximately equal to the overall pressure difference existing between the front surface of the first bellows and the rear surface of the last bellows, and indicator or transmitter means, the movement or displacement of which is proportional to the overall pressure difference, the indicator or transmitter means being provided for indicating the overall pressure difference or for transmitting said movement. In a first embodiment, Fig. 1, the device comprises three bellows 1, 2, 3 having their bases rigidly connected to an indicator driving shaft 13 and an arrangement of pistons 19, 25, so connected and proportioned that the pressures in the regions between the bellows, regions I, II both of which are filled with liquid, are such that each bellows is acted on by approximately one third of the total pressure difference between the service and counter pressures which are applied to bellows 1 and 3 respectively. In a second embodiment, when a sufficiently high rate of flow can be obtained, the pistons can be replaced by orifices or throttles 36, 37, Fig. 3, which are so dimensioned that the speed of flow through them is that of the speed of sound. If desired a pressure valve 40 can be incorporated so that the device cuts out at low pressures. This principle can be applied direct to the bellows, as in a further embodiment, Fig. 5, where the flow is into the region O through orifices 36, 37 in the bases of the bellows and out through a side pipe from the region II. The same result is said to be achieved by merely partially filling the regions I and II with some volatile liquids of different vapour pressures, e.g. propane and butane (Fig. 6, not shown). A further embodiment is described for controlling the pressure of fluid flowing in a pipe (see Group XIX). Specification 698,682 is referred to.

Title: Improvements in or relating to electric signalling and to visual indication
IPC: G08C15/08
Filed: 1946-01-03
Abstract: 622,280. Cathode-ray oscillographs. STANDARD TELEPHONES & CABLES, Ltd., DUNN, R. H., and MCWHIRTER, E. M. S. .Tan. 3, 1946, No. 270. [Class 37] [Also in Group XXXVIII] In a visual indication system for displaying a plurality of signals, the beam of a C.R. tube is deflected in steps along the X-axis, while the signals deflect the beam along the Y-axis, the application of each signal being timed by a distributor to coincide with a particular step in the X-deflection of the beam, so that a plurality of indications are displayed, corresponding to the strengths of respective signals. In Fig. 1, an oscillator 1 supplies a squaring circuit and differentiating circuit 2, producing a series of alternating positive and negative voltage peaks, which are amplified at 3 with suppression of negative peaks. The positive peaks are applied to a distributer circuit 4, which may employ a counting train of cold cathode tubes, each of which controls one of the gate circuits 5, 6, 7, 8, to which A.C. signals modulated by the quantities to be indicated, are supplied. Each gate opens in sequence, allowing each signal in turn to enter a high-pass filter 9, an amplifier 11, a connecting line, and an amplifier 18, Fig. 2. One distributer channel and gate circuit is reserved for the transmission of a synchronizing signal distinguished from the indicating signals by its frequency, or otherwise. A portion of the output of oscillator 1 is supplied to the amplifier 11 through a low-pass filter 10. The indicating signals are separated from the output of the amplifier 18 by the filter 19, demodulated, and applied to the Y-plates of a C.R. tube 28. The signal from the oscillator 1 is separated by the filter 21, converted to a square wave by the pulse shaper 23, differentiated and amplified at 24, and emerges in the form of recurrent alternate positive and negative pulses, which are fed to the rectifier and integrator unit 25. The positive peaks are suppressed and the negative peaks successively charge a condenser, the voltage across which is applied to the X- plates of the C.R. tube, deflecting the beam in a series of steps..Once in each cycle of the distributer operation, a synchronizing signal is fed to the line, separated by the filter 20, and applied to the flyback circuit 26, which discharges the condenser supplying the X-plates, causing the deflected beam to return to its starting point and to resume its stepping motion in the X-direction. The cycle of operation of the distributor circuit is continuous, and a succession of superimposed images appear on the C.R. tube screen, giving a continuous display of the quantities to be indicated, which may amplitude, phase, or frequency modulate a source of A.C. which is applied to, the distributer gate circuits. The Provisional Specification refers to the use of the invention for multiple telemetering over a single transmission channel.

Title: Manufacture of thickness differential alloying hot dip galvanized steel sheet
Inventor: KIYASU TETSUYA
IPC: C23C2/26
Filed: 1988-01-05
Abstract: PURPOSE:To manufacture a thickness differential alloying hot dip galvanized steel sheet excellent in powdering resistance by precipitating specific amounts of Ni on the thick-coating side, with high zinc coating weight, of a steel sheet, subjecting the above steel sheet to reducing annealing, and then applying differential hot dip galvanizing and applying heat treatment to the above. CONSTITUTION:A steel sheet is subjected to reducing annealing to undergo the removal of surface oxide film. Subsequently, this annealed steel sheet is dipped in a hot dip galvanizing bath to undergo plating, and further, coating weight is regulated so that coating weight at the outside surface is different from that at the inside surface. Successively, alloying heat treatment is applied to the plate surface. In the above- mentioned method for manufacturing the thickness differential alloying hot dip galvanized steel sheet, Ni is previously precipitated, prior to the above reducing annealing, by >=0.1g/m<2> and, preferably, <=about 5g/m<2> only in one side having high zinc coating weight by an electroplating method, etc. Further, an Fe-P alloy layer is applied by >=3g/m<2> at least to one side of the above alloying hot dip galvanized steel sheet, if necessary. By this method, the thickness differential alloying hot dip galvanized steel sheet which is excellent in powdering resistance and in which cratering is prevented can be obtained.
