A valve has a deformable closure member 2 movable relative to two seats la, 1b by a manually or thermostatically operated lever 8 which moves vertically on rotation due to the co-operation of two sets of three pins 10a, (11a), (12a), 10c, (11c), (12c), at different radial distances from the axis of rotation with two sets of three arcuate ramps 10, 11, 12, 10b, 11b, 12b at correspondingly different radial distances formed respectively on a valve body cover 14 and two platforms 9, 17 rotatable with valve stem 7. The closure surface is frusto-conical adjacent its periphery so that it contacts first seat 1a and after subsequent deformation seat 1b. The members on which the pins and ramps are formed may be interchanged. In a modification a platform on which pins or ramps are formed is rotatable between a cover and a platform having co-operating ramps or pins thereon and secured to the valve body. The closure member surface is flat and co-operates with a pair of seats of different height. In a further modification, a diaphragm spring biases the closure member upwardly and a single rotatable platform with pins co-operates with a cover with corresponding ramps.

Title: Method of producing hydrocarbons
Inventor: HEININGEN JAN VAN
IPC: E21B43/17
Filed: 1964-11-30
Abstract: 1,021,607. Wells &c. SHELL INTERNATIONALE RESEARCH MAATSCHAPPIJ N.V. Nov. 30, 1964, No. 48656/64. Heading E1F. Hydrocarbons are produced from a formation 1 penetrated by an injection well 4 and a production well 5 by creating a single fracture 6 between the wells and adjacent the top of the formation, by injecting a medium having a S.G. greater than the mean S.G. of the hydrocarbons into the well 4, and by producing hydrocarbons from the well 5. The medium is at a temperature higher than the original temperature of the hydrocarbons in the formation, and consists mainly of water. In view of its S.G. the medium sinks into the formation displacing the hydrocarbons upwardly towards the fracture. In modifications rows of injection wells alternate with parallel rows of production wells, and production wells are arranged about a central injection well. In further modifications the invention is applied to superimposed formations separated by impermeable layers, and the wells are multi-completion wells.

Title: A brake control system for wheeled vehicles
Inventor: KULLBERG OTTO GOSTA
IPC: B60T8/70
Filed: 1969-10-09
Abstract: 1,237,618. Anti-skid braking systems. O. G. KULLBERG and O NORDSTROM. Oct.9, 1969 [Oct. 22, 1968], No.49656/69. Heading G1N. [Also in Division F2] The braking system of a four-wheeled vehicle is controlled automatically to prevent the speed of any wheel differing from an intermittently corrected reference speed by measuring the speed of each wheel, calculating the deceleration in intervals determined by a timer and de-energizing the brake of any wheel whose slip exceeds a predetermined value. As shown, each wheel is associated with a pulse train generator 1-4, whose frequency is proportional to angular speed. Signals from the rear wheel generators 3, 4 are fed alternatively by relay 6, together with clock pulses from timer 5 to unit 7, to provide a speed signal, and unit 8, to provide a deceleration signal. If the latter does not exceed a predetermined value, the former is passed via relay 9 to a reference speed calculator 10. The reference speed signal is stored in unit 10 for one time interval and recalculated during that interval in accordance with the change in speed, as measured by unit 7, and the length of the time interval, which may be constant or varied inversely with the calculated deceleration. The generators 1-4 also feed their signals to individual units 19-22, where they are combined with the reference speed signal to calculate wheel slip, and to individual units 23-26, where they are combined with the clock pulses to calculate deceleration. When the slip and deceleration signals exceed predetermined values in combination, a following relay 15-18 is actuated to energise a valve 11-14 which cuts off the braking pressure on the appropriate wheel.

Abstract: 1319325 Construction of differential pressure flow meter tubes GENERAL SIGNAL CORP 3 Nov 1970 [3 Nov 1969 22 June 1970] 52281/70 Heading G1R A flow metering device of the pressure differential producing type includes a tube having a wall defining a throat 13 and a converging section 14 for guiding fluid thereto from an inlet region of larger cross-section 12, there being pressure taps for sensing pressure in the inlet region and in the throat 16, 17 wherein the shape of the tube wall is adapted to cause the fluid, at least once during its passage from the inlet region to the throat pressure sensing tap, to form a vena contracta and then to expand and re-attach to the wall at a point downstream of the vena contracta. As described the differential pressure is produced by a tube 11 of the Venturi type in which the wall includes a truncated conical section 18 tapering from an inlet region 12 to a throat region 13 and having a sharp continuous edge 21 at the throat end which produces a vena contracta in a liquid flowing through the tube.

Examples are described of tubes which produce one only vena contracta, Figs. 8, 9 (not shown) and four vena contracta, Fig. 6 (not shown). The upstream pressure tap 16 may be in the inlet region or after the first vena contracta, Fig. 6 (not shown) In all cases the throat pressure tap is situated at a point after the vena contracta at which the fluid is again attached to the wall of the tube in order to determine the true static pressure.

Abstract: 1,071,993. Processing nuclear energy spectra. PHILIPS ELECTRONIC & ASSOCIATED INDUSTRIES Ltd. Dec.10, 1965 [Dec.15, 1964], No. 52557/65. Heading G1A. A device for comparing two energy spectra stored in a memory by scanning the spectra and subtracting one spectrum multiplied by an adjustable weight factor from the other spectrum is characterized in that the ratio between the speeds of scanning the two spectra is adjustable and the magnitude of one spectrum is reduced by the weighted average of the part of the other spectrum scanned during the same period. An unknown spectrum is stored in a 200 channel store MA and a known spectrum to be subtracted is stored in store MB. The contents of these stores are read serially into buffer registers BA and BB at speeds governed by the pulse generators GA, GB. The frequency of generator GB is variable to take account of differences between the energy scales on which the spectra in MA and MB were recorded. Digital-analogue converters DA, DB pass the contents of BA, BB through transistors T 1  T 2  to be combined in opposite polarity on the capacitor C 1 . The charge on C 1  is periodically transferred to a further capacitor C 2  through transistor T 3  by a pulse from the control unit CU. C 2  controls the vertical deflection of a cathode ray oscilloscope KB the sweep of which is derived from GA via TA. The proportion of the known spectrum subtracted from the unknown spectrum is varied by adjusting a potentiometer PP whilst observing the combined spectrum on KB. In a modification which operates entirely digitally, Fig. 4 (not shown), the capacitor C 1  is replaced by an accumulator (AC) receiving the count from the buffer register (BA) and a scaled down count from (BB).
