Title: Improvements in or relating to siphon-valve stoppers
IPC: B67D1/04
Filed: 1970-06-17
Abstract: 1293195 Dispensing liquids by gaseous pressure SOC D'EXPLOITATIONS ET DE REALISATIONS INDUSTRIELLES ET COMMERCIALES 17 June 1970 [19 June 1969] 29436/70 Heading FIR [Also in Division F2] A siphon valve stopper for fitting to a glass bottle comprises a CO 2  cartridge 31 whose gas pressure is reduced and regulated by a device 30 which includes a regulating piston 66 in a lowpressure chamber 67 controlling a check-valve 63, the device 30 also being adjustable so that the valve 63 acts as a stop valve. Before fitting to a bottle a knob 94 is rotated to raise piston 66 so allowing the check-valve 63 to engage a seat 57b and the cartridge 31 is pierced by a perforator 55. After fitting, the knob 94 is counter-rotated causing the piston 66 to engage a rod 63a and unseat the check-valve 63 to allow gas to flow through an opening 62 and ducts 71, 72 to the bottle's interior. Should the pressure in chamber 67, which may be pre-set by a screw 69, become too great the piston 66 rises and uncovers an orifice 99 so venting the gas to atmosphere. The stopper is held in place on the bottle by a bung 51 and a spring 7. In a second embodiment, Fig. 2, the cartridge 31 is located in a removable housing 117b forming part of a handle the remainder of which houses the device 30. The stopper is held in place by an annular sealing ring 113 and a threaded clamping collar 114. Openings in the screw 69 and a groove 126 in the wall above the low-pressure chamber 67, permit venting of the gas.

Title: Improvements in or relating to seismic surveying
IPC: G01V1/047
Filed: 1965-07-12
Abstract: 1,112,654. Seismic surveying. GENERAL DYNAMICS CORPORATION. 12 July, 1965 [13 July, 1964], No. 29447/65. Heading H4D. A seismic source is controlled by a generator responsive to a starting signal to produce a signal of predetermined frequency and predetermined number of cycles, the signal being applied via delay means to the seismic source. The invention is applied to the control of an array of seismic sources each of which may be constructed as described in Specification 1,112,653 and is actuated by hydraulic pressure controlled by an electrically operated valve 12. The control apparatus includes means 14 for generating a signal of predetermined frequency and number of cycles in response to a trigger signal, the output of means 14 is coupled to driver circuits 16, one for each valve; each driver circuit includes a circuit 18 for delaying the output of means 14 by a predetermined time and being adjusted such that the seismic waves are focused into a beam. In the operation of a seismic source hydraulic pressure is conducted to cylinders by energizing a torque motor, the pressure in the cylinders being modulated by varying the control signal to the torque motor. To facilitate discrimination of seismic signals from noise a train of sinusoidal signals is afforded by feeding a square-wave signal having a number of cycles to a servo control means 20 coupled to the torque motor, the frequency response of a seismic source being such that, even though the signal is a square wave, sinusoidal seismic waves are produced. The square wave is generated by a transistor bi-stable multivibrator 78 with emitter triggering by a relaxation oscillator incorporating a unijunction transistor 94. An adjustable circuit 108 provides for frequency control of multivibrator 78. The relaxation oscillator is switched on and off by a transistor 126 controlled by a bi-stable multivibrator 130 flipped to its " stop " state when a preselected number of pulses have been generated. Delay means 18 includes a rectifier bridge 138 the pulses at the output of which are fed to an adjustable and fine delay monostable multivibrator 144. The output of multivibrator 144 passes to a course delay means 146. The output of delay means 18 is coupled to the torque motor 49 via a olosedloop servo control circuit incorporating a differential amplifier 162 and stability improvement by means of a differentiator 182. The length of each wave train is set by the adjustment of a counter 136, and the onset of a wave train can be controlled from seismic magnetic recording apparatus. To effect a beam from an array of seismic sources, means are associated with each source except one for delaying the signals applied to each of the respective sources relative to those applied to the one source.

Abstract: 715,635. Kinematograph apparatus. ELECTRIC & MUSICAL INDUSTRIES, Ltd. Dec. 19, 1952 [Dec. 22, 1951], No 30068/51. Class 97(1) [Also in Group XL(b)] Apparatus for scanning intermittently moving kinematographic film (for generating or recording television signals or pictures respectively) employs at least two film gates the film being stationary during scanning in one gate whilst the pull-through is operating in the other gate or gates. The arrangement employing two scanning positions is shown in the drawings and comprises two film gates 13, 14 past which the film 1 is guided by means of idle sprockets 2, 4 and driven sprockets 3 and 5, the latter being driven intermittently by means of pull down mechanism 6 and 7. In operation, the image to be recorded (or the scanning raster, when the apparatus is employed to generate television signals) which is developed on the screen of tube 15, is arranged to focus separate images on the gates 13, 14 by means of an optical splitter 17 and the pull-down mechanisms 6, 7, which are driven synchronously with the scanning action of the tube by means of motor 8, are arranged to operate alternately so that when the film is stationary in one of the gates and exposed to the image focused thereon (via an aperture in one of the shutters 20, 21 which are also driven by motor 8) the film in the other gate is being advanced and is obturated by an opaque portion of the other shutter. In setting up the apparatus a loop of film 24 is formed between sprockets 3 and 4 of such length that alternate film frames are scanned in one gate whilst intervening frames are scanned in the other gate. Each film frame may be exposed for the duration of a television picture or field period and if each picture contains more than two fields the number of scanning gates is correspondingly increased: When the apparatus is employed to generate picture signals by scanning exposed film the tube 15 functions as a " flying-spot " scanner and photo-electric cells (the outputs of which are combined) are positioned behind each gate. In a modification the apparatus is applied to recording television pictures of 16 mm. size in a side-by-side position on 35 mm. film one picture being recorded near one edge of the film and the next picture near the other edge of the film and displaced along the length of the film by the film path difference between the two gates. Methods of printing standard film from film recorded in the apparatus and of printing film suitable for use in the apparatus (e.g. for generating television signals) from standard film are described. Specification 698,574, [Group XL(b)], is referred to.
