Title: Improvements in or relating to apparatus for filling bottles or other containers with gas charged liquids
IPC: B67C3/26
Filed: 1960-12-29
Abstract: 975,404. Bottling. M. & E. GODDARD Ltd., and B. S. DICKINSON. Dec. 14, 1961 [Dec. 29, 1960], No. 44546/60. Heading B8T. Bottles or other containers are filled with gas-charged liquids by counter-pressure type apparatus in which the liquid is stored under pressure in an annular reservoir 10 having a number of circumferentially spaced filling heads to which successive bottles are applied, and each head has concentric gas and liquid filling tubes 27 and 26 respectively under the control of valves disposed respectively above and below the liquid surface 13. The seating 43 of each head with which the mouth 44 of the bottle to be filled engages, is carried by a sleeve 35 vertically slidable on a rod 36 and movable under pressure from the bottle to open the said valves. The gas valve comprises a loose lift valve 16 within a hollow ported housing 15 on a column 14; in the closed position the valve engages a nipple 24 which communicates by way of piping 25 with the gas tube 27. The nipple is carried in a vertically movable block 21 fixed to a tappet 18 spring-urged downwardly. A spring-loaded plunger 23 in the block is aligned with a tappet 19 to urge the liquid valve 29 closed against the action of a weighted lever 30 pivoted to the column. A ring 38 rotatably mounted on the sleeve carries a stepped block 50, the highest part of which engages a push rod 40 when the filling operation is commenced and the sleeve is urged upwardly by the neck of a bottle. The nipple is then removed from the valve 16, Fig. 2, and the bottle charged with gas up to the pressure existing in the reservoir; angular movement of the ring 38 is then effected to bring a lower portion of the stepped block beneath the rod 40 so that the nipple is brought close to the valve 16. When the pressure in the bottle and reservoir are equalized the valve 29 is automatically unseated under the influence of the lever 30, and resultant filling of the container occurs, and the displaced gas returns to the reservoir by way of tube 27. Should the bottle burst during this filling stage the valve 16 wil automatically contact its nipple, and the resultant pressure build up will cause the liquid valve to close. When the filling is completed a further angular movement of the ring 38 brings the block 50 clear of the rod 40 so that the said valves close. To prevent the liquid foaming over the bottle neck, the gas pressure above the contained liquid is vented by a snifting port 52 normally closed by a valve 53 but opened automatically just prior to disengagement of the bottle. The valve 53 is mounted at one end of a spring-loaded pivoted rocking lever operated by engagement with a roller. The bottles may be fed on to a turntable and pushed against their filling heads throughout a predetermined angular travel of the table and heads about a common vertical axis, the control ring 38 being turned by automatic means. The reservoir may, alternatively, be cylindrical, or each filling head may have its own small reservoir.

Title: Surface measuring instruments
IPC: G01B7/312
Filed: 1975-09-18
Abstract: 1492401 Determining the centre of curvature of a body RANK ORGANISATION Ltd 18 Sept 1975 [24 Sept 1974] 41561/74 Heading G1N The invention relates to a method of determining the co-ordinates of the centre of curvature of the curved surface of a workpiece with respect to a predetermined frame of reference, the origin of which coincides with the centre of relative rotation between the workpiece and a sensor of a surface measurement instrument of the type comprising a table on which the workpiece is mounted and the sensor, the table and sensor being relatively rotatable about a fixed axis. The method comprises the steps of traversing the sensor over the workpiece surface and deriving from the sensor output three signals representing the value of the radial distance of the workpiece from the fixed axis at three points along the traverse of the sensor the middle point lying at the intersection of one of the axes of the predetermined frame of reference and the workpiece surface, and the other two points extending an angle Ï with the middle point at the fixed axis, and deriving from these values two output signals representing the expressions, and where x and y respectively represent the coordinates of the centre of curvature of the workpiece parallel to and perpendicular to the said one axis and r 1 , r 2 , r 3  represent the radial distance at the three points in order along the traverse. For a workpiece with a rough surface the value of the radial distance of each point may be the average distance over a range about the point. These ranges should not overlap but are preferably contiguous. The method may be used for centring a workpiece  on the table, the centring being effected automatically on the co-ordinates of the centre of curvature thereof being evaluated. For accuracy after the first "centring" the method may be again carried out, followed by a second "centring" the process being repeated as required. The apparatus for carrying out the method comprises a potentiometer 21 which monitors the rotation of the motor spindle and four connected potentiometers 22, 25, 33, 34, the first 22 setting the angle Ï and with the potentiometer 21 controls the motor, the second 25 providing the value of 0 to a computing portion of the apparatus and the third 33 and fourth 34 deriving the values sin Ï and 1 - cos Ï respectively. Integrators 30 and 31 under the control of integrator switching and scaling circuit 27 derive from the range of sweep of the sensor about each point the values of r 1 , r 2  and r 3 , the output of integrator 30 representing the expression 2r2 - (ri + r3) and the output of integrator 31 representing the expression r 3 -r 1 . These representations are scaled by the outputs of potentiometers 34 and 33 respectively and the values of y and x so produced are then displayed.

Abstract: 1,016,915. Pressure gauges. SOC DE PROSPECTION ELECTRIQUE SCHLUMBERGER. Nov. 29, 1962 [Jan. 6, 1962], No. 45202/62. Headings G1L and G1N. In a transducer for measuring fluid pressure comprising a hollow cylinder 18 (Fig. 1) of magnetic material, containing two coils 24, 26 with their axes at right angles, which are used to make the cylinder vibrate axially and/or radially at its natural frequency, this frequency being indicative of the magnitude of the fluid pressure on one face of the cylinder, a ring member 40 held by a bellows 30 is added, to produce compensation for variations in pressure due to changes in temperature. The inside of cylinder 18 is filled with gas at a low pressure, so that the absolute change in pressure inside the cylinder with changes in temperature are small. The chamber 42 between the outside of cylinder 18 and an external casing 10 is filled with a standard fluid, and is in communication with the bellows 30 whose free end 34 carries a rod 36 attached to the ring member 40. When the temperature of the fluid in chamber 42 rises the bellows 30 expands, accompanied by a decrease in the density of the fluid, and by a shift of the ring 40. Each of these alterations affects the oscillatory frequency of the cylinder 18, and it is shown that there are two positions of the ring 40 at which they are equal and opposite, these positions being found experimentally. The ring 40 may be provided with lobes 41 (Fig. 5). In operation the external surface of bellows 30 is subjected to a fluid pressure which is transmitted through the bellows to the external surface of the cylinder 18, and determines its natural oscillations frequency, which is measured electrically. In another embodiment (Fig. 6, not shown) the inside of cylinder 18 is also subjected to a test pressure via a bellows, and the vibrating frequency indicates the pressure difference. The fluid inside chamber 42 is preferably a mixture of decane and tetradecane whose ratio is adjusted to give a predetermined basic frequency of oscillation.

Filed: 1964-11-06
Abstract: 1,082,486. Electric control systems. ROBERT BOSCH G.m.b.H. Nov. 6, 1964 [Nov. 9, 1963], No.45246/64. Heading G1N. In an electrically controlled fuel-injection system of an I. C. engine 10, Fig. 1, the pressure in the inlet manifold 12 of the engine is measured by a barometric device 27 which varies the inductance of a coil 26 in accordance with the said pressure. Coil 26 is supplied with A. C. through a series resistor, the voltage developed across the coil being amplified in a transistor amplifier 29, rectified at 58, and used to control the duration T of pulses 21 produced by a monostable multi-vibrator 20. The coil is housed in an annular recess in a cylindrical ferrite core (33), Fig.4 (not shown), and a bellows (31) responsive to manifold pressure is connected by a non- magnetic, insulating, axial shaft (35) to an armature comprising an insulating plate (37) carrying, on its face adjacent the core (33), a magnetic disc (38). Fig. 5 depicts the circuitry of the system. The voltage developed across the pressure-dependent inductance 32 is impressed upon the first stage of a three-stage transistor amplifier through a voltage biased rectifier 41, so that only the crests of alternate half-cycles are passed to the amplifier. The output stage of the amplifier is connected via a transformer to a full-wave rectifier bridge 58, the output of which is used to bias a transistor 73 which forms a variable discharge resistance path for a capacitor 75 serving as part of a timer circuit for a multivibrator constituted by transistors 71, 72. The unstable state of the multi-vibrator, during which transistor 72 is blocked and a power transistor 86 provides an output pulse through windings 18 of injection valves 13, is initiated in synchronism with engine-speed by the closing by a cam 82 on the crank-shaft of contacts 80, 81 to connect the base of input transistor 71 to earth through a capacitor 78; the duration of the output pulses depends upon the bias on transistor 73, and hence on pressure. The pulses may also be used for other purposes, e. g. electro-magnetically controlled starting, gear-changing, and ignition timing.
