Title: Fluid pressure operated shut-off valve
IPC: E21B34/02
Filed: 1960-05-06
Abstract: 914,111. Fluid-pressure servomotor-control systems. WILLIS OIL TOOL CO. May 6, 1960 [Nov. 23, 1959], No. 16158/60. Class 135. A shut-off valve suitable for use at oil or gas well heads and operative to close in reponse to abnormally high or low pressures or the attainment of a predetermined level of fluid in a tank supplied through the valve comprises a main valve member 23 coacting with a seat 22 between an inlet 19 and an outlet 21 and attached to a piston 29 which is reciprocable in a bore 28 vented to atmosphere at 30a, carries a position indicator rod 95a, and is controlled by pilot valves 81, 107. The pilot valve 81, which is biased in the opening direction by a spring 91, an adjustable abutment 92 of which coacts with calibrations (not shown) on a support 85, is normally held against its seat 42 by pressure in the outlet 21 acting through a conduit 89, containing a valve 88, on a piston 82 but in the event of abnormally low pressure the pilot valve is opened to permit the application of inlet pressure through passages 68, 54, 57, 44, 40 to a chamber 95 to close the main valve. In the event of excessive pressure in the inlet 19 the pilot valve 107, which is subject to that pressure on its conical surface between its seat 52 and a fitting 55, will be opened against its loading spring 109, which has an adjustable abutment 111 coacting with calibrations (not shown), to allow the application of pressure to the chamber 95 to close the main valve. The pilot valve 107 can also be opened by application of pressure to a piston 105 by the opening of a valve 121 responsive to the level of fluid in the tank. For reopening the main valve the passage 68 is interrupted by a manually-operated valve (not shown) and the chamber 95 is vented by a further manually-operated valve (not shown) to allow inlet pressure acting on the main valve member to effect the reopening. A source of high fluid pressure may be connected at 135 for cleaning the pilot valve passages &c. Pressure gauges may be connected at 103, 138.

Title: Production of unsaturated hydrocarbon chlorides
IPC: C07C17/154
Filed: 1962-05-01
Abstract: Unsaturated chlorohydrocarbons are prepared by reacting an alkane of at least two carbon atoms, an oxygen-containing gas, and chlorine and/or hydrogen chloride as chlorinating agent in the presence of a metal halide catalyst at 470-550 DEG C., the utilisation of the chlorinating agent being maintained at 70-90% of the amount fed, and the amount of oxygen being 0,2-2,4 moles per mole of chlorinating agent.  Suitable catalysts are chlorides of multivalent metals such as Cu, Fe and Cr, which may also be used together with other metal halides, such as alkali and alkaline earth metal chlorides.  Suitable catalyst carriers are silica, alumina, fuller's earth, kieselguhr, pumice, and diatomaceous earth.  In examples, ethane produces mainly vinyl chloride, together with other chlorohydrocarbons, saturated and unsaturated.

Title: Improvements in or relating to colour television transmission
Inventor: BEDFORD LESLIE HERBERT
IPC: H04N9/083
Filed: 1952-07-02
Abstract: 738,386. Television. MARCONI'S WIRELESS TELEGRAPH CO., Ltd. June 23, 1953 [July 2, 1952], No. 16681/52. Class 40 (3). In a colour television transmission system in which the object to be televised is imaged on the camera tube via a multi-colour strip filter, the different colour strips have different " pitches" " so that in the camera tube output the signals corresponding to different colour components are modulated at different and therefore separable frequencies determined by the different pitches of the colour strips. The filter comprises two superimposed sections, one consisting of cyan strips and the other of yellow strips, each section having transparent strips between the colour strips and in the described embodiment the yellow strips are twice as wide as the cyan strips and the filter is positioned with the strips at right angles to the direction of line scanning in the camera. Fig. 1 (Prov.) shows the manner in which the two sections are superimposed, the cyan strips being designated R (red signal producing) and the yellow strips marked B (blue signal producing) so that the colour sequence of the composite filter when viewed by transmitted light is " green "; " yellow " ; " cyan " ; " white." With " ideal " filter strips (i.e. the cyan strips fully suppressing red and the yellow strips fully suppressing blue) the distribution of red and blue is as shown in Figs. 2 and 3 (Prov.), but in practice, due to filter imperfections, the actual modulation signals are contaminated by " colour crosstalk " and signals of the form shown in Figs. 4, 5 and 6 (Prov.) are obtained for the green, red and blue primaries respectively. This " cross-talk " may be reduced either by employing a suitable additional filter, e.g. a composite filter having a small gradation in magenta (minus green) to eliminate the green strip frequency modulations and small gradations in cyan and yellow in the case of the red and blue or, alternatively, by employing a suitable electrical filter network which performs a matrix transformation to produce the true primary colour modulations. With an " ideal " filter the camera output signal is of the form of a normal video signal with the green component emphasised (i.e. G+¢R+¢B-which may be corrected to a signal of correct brightness, i.e. ¢(G+R+B) by including a uniform magenta filter with a transmission factor of ¢ in the optical path) together with Rand B components which are in effect modulated on two different carrier frequencies determined by the pitch of the cyan and yellow strips in the composite filter. These latter signals are separated by conventional electrical filter networks and the arrangement therefore provides a colour television signal comprising red, blue and brightness signals (Fig. 7, Comp., not shown).
