Title: Control of chokes
IPC: G05D3/00
Filed: 1974-04-29
Abstract: 1499985 Oil well choke control BRITISH PETROLEUM CO Ltd 8 April 1975 [29 April 1974] 18663/74 Heading G3N An oil well choke (i.e. for restricting oil or gas flow in an oil well flow line) is retroactively electrically controlled. The choke has two discs each formed with two circular diametrically opposed apertures, one disc being relatively rotated with respect to the other to restrict the flow. The control system produces a first electric signal indicating required choke position and a second electric signal indicating actual choke position using amplifiers A1-A4 connected to differential amplifiers A5-A7. A positive voltage output from amplifier A5 actuates trigger circuit VT1, VT2 to cause transistor VT3 to conduct and energize relay RLA. This primes a solenoid actuation circuit in one direction for the choke. A negative voltage output from amplifier A7 actuates trigger circuit VT8, VT9 to cause transistor VT10 to conduct and energize relay RLB. This primes a solenoid actuation circuit in the other direction for the choke. A positive or negative voltage output from amplifier A6 switches off transistor VT4 or VT5 and de-energizes normally energized relay RLB which primes the solenoid actuation circuit for both directions. The circuit can be actuated remotely by a telemetry system for offshore wells and, if faults arise, the choke can be locked in position and an alarm lamp lit. A calibration unit Fig. 2 (not shown) is also described.

Abstract: 1,118,398. Safety belt. T. TOREN and P. MEYER. 24 April, 1967 [9 May, 1966], No. 18792/67. Heading A3V. A device for retracting a safety belt 13 when not in use consists of a cylindrical housing 10 which can be pivotally mounted on the vehicle, the housing 10 having a slot 11 through which the belt 13 passes and a spring loaded drum 15 on which the belt 13 is wound. One end of the belt 13 is looped around the drum 15, the loop being formed by stitching 17 and is secured to the drum 15 by rivets 18. A leaf spring 22 folds the loop in the belt 13 when the belt is retracted. The drum 15 is rotatably mounted in plates 14 and is held in position axially by circlips 16. A mandrel 23 is mounted within the drum 15 and a torsion spring 26 is connected at one end 28 to the drum 15 and at the other end to the mandrel 23. The mandrel 23 is prevented from rotating about the axis of the drum by a pin 24 but can slide along the pin 24 and can pivot about the axis of the pin 24. The device may be connected to a vehicle floor by a lug 32 on the housing 10 using a J-bolt. In a modification (Fig. 5) the device is pivotally mounted on a pin 63 in a housing 51 secured beneath the vehicle floor 52. The belt passes through a slot 58 in a plate 57 and is protected by a plastic sleeve 54.

Filed: 1972-04-26
Abstract: 1380608 Laminating method JOHNS-MANVILLE CORP 26 April 1972 [3 May 1971] 19314/72 Heading B5N A method of forming a laminated structure comprises advancing a layer of woven rovings along a first path, applying adhesive to the woven rovings while advancing along the first path, applying heat to the adhesive and woven rovings while advancing along the first path; advancing a chopped strand web containing a thermoplastic binder along a second path intersecting the first path, contacting the web with the adhesive coated face of the layer at the intersection, pressing the web and the layer together and cooling the resultant laminate, the laminate being supported during cooling and until the adhesive and binder solidify in such a manner that the web is supported on one side with a conveyer surface and on the other side by the layer of woven rovings. In the embodiment shown, the woven layer 10, e.g. woven glass rovings is unwound from roll 27, fed on to the primary conveyer belt 16 past an adhesive applicator 18 and a heating station 20, the adhesive, e.g. a propoxylated bis-phenol-A fumarate polyester being deposited in powdered form on to the upper surface of the layer and softened at the heating station. The chopped strand web 14, e.g. of glass fibres is fed from roll 17 and forced into contact with the adhesive by the roller 26 at the end of the primary conveyer belt. The resultant laminate is then directed downwardly to a return conveyer belt 30 thereby inverting the laminate which is cooled by a high velocity stream of cooling air from duct 32 and wound on mandrel 38 with the woven layer facing, outwardly. The binder may be identical with the adhesive. The heater 72 of the heating station 20 comprises electrically heated radiant elements or a gas fired panel and is equipped with withdrawal means for use in a stoppage. Means are provided in the apparatus for aligning the web and the layer. The laminate may be slit after manufacture and may be used in the production of plastics bodies.

Title: Improvements in and relating to electric bridge modulators
IPC: H03C1/58
Filed: 1936-07-13
Abstract: 456,574. Modulating systems. SIEMENS & HALSKE AKT.-GES., Siemensstadt, Berlin. July 13, 1936, No. 19403. Convention date, July 13, 1935. [Class 40 (v)] In a carrier-suppression bridge modulator employing four rectifiers, accidental differences in the impedance of the rectifiers are prevented as far as possible from affecting the balance of the modulating circuit, by arranging the rectifiers in suitable order in the circuit. As shown, the rectifiers 1 ... 4 are arranged as a bridge with the modulation applied by a, transformer UI across one diagonal, the output taken from the other diagonal by a transformer UII, and the carrier H applied at the mid-points of the transformers. The rectifiers are arranged so that 1 and 2 are of extreme impedance, and 3 and 4 of intermediate impedance ; or 1 and 2 may be intermediate and 3 and 4 extreme. Either of these arrangements results in less carrier in the output than any other arrangement of the same four rectifiers would give. The Specification shows that the second harmonic of the carrier is present in the output current, and indicates that this may be lessened by a choice from the alternative arrangements referred to above. The carrier may be still further reduced by displacing the tappings on the transformers UI, UII.

[Also in Groups XL (a) and XL (c)] In a pulse generating circuit of the type in which a reservoir circuit is charged through an inductor and rectifier from an A.C. source and then discharged through a load circuit by a triggered discharge device to generate the pulse, a protective discharge circuit which comprises an impedance and a breakdown discharge device is connected between the high voltage electrode of the triggered discharge device and a point of fixed potential so that the breakdown device conducts above a predetermined excess voltage. The Figure shows a pulse generator in which a pulse forming network 1 is charged from a voltage supply via an inductor 3 and rectifier 4 and is periodically discharged through the auto-transformer 5, with which the magnetron load 6 is associated, when the ignitron 2 is triggered. To obviate the build-up of excess voltage at the anode of the ignitron 2 and thus at the load 6 which might occur if the magnetron 6 became temporarily shortcircuited, a protective network comprising a self-quenching spark gap 8, see Group XL (a), is connected in series with an impedance 7 so that at a given excess voltage at the anode of ignitron 2 the gap 8 breaks down and removes the excess voltage. The gap is self-quenching and in this is assisted by the action of impedance 7 which is preferably a material whose impedance falls with increase of voltage, e.g. the material having the Registered Trade Mark " Metrosil."
