Title: Measuring apparatus
IPC: G01F1/58
Filed: 1955-09-12
Abstract: 789,102. Electric tests. FOXBORO CO. Sept. 12, 1955 [Sept. 14, 1954], No. 26104/55. Class 37. The Specification relates to induction flowmeters in which the fluid cuts a transverse magnetic field and thus has produced in it a voltage which is proportional to the rate of flow and is measured by electrodes positioned on a line perpendicular both to the magnetic flux and the direction of fluid flow. According to the invention the flux is produced by means of a pair of identical coils on opposite sides of the pipe, the planes of the coils being parallel and perpendicular to a line from their centres and the turn of the coils forming a compact conductive mass at an approximately uniform distance from the coil centre. As shown, the stainlesssteel pipe 10 has opposite ends threaded so that it may be coupled in a flow system. The interior of the pipe is provided with an insulating liner for example vitreous enamel baked directly on to the inner wall or a thin layer of chemical and heat-resistant plastic. Coils 16, 18 of approximately rectangular form are used to produce the magnetic flux and are A.C. energized in parallel so that the fluxes are additive. A plan view of the top coil is shown in Fig. 2, the sides of the coil parallel to the pipe being bent downwardly as shown in Fig. 1. The coil sides perpendicular to the pipe are held in clamps 42 which are supported on bridges (not shown) welded on the pipe. The " windows " of the coils have a longitudinal dimension of from 1 to 3 times the pipe diameter. Surrounding the coils 16, 18 is a continuous laminated core 40, of any transformer iron, preferably silicon steel which serves as a split low reluctance return path for the flux passing through the pipe. The core shown is held by a clamp 54. Electrodes 20, 22 are positioned 180 degrees apart in the walls of pipe 10, from which they are insulated. The external stem of the electrodes are connected to output leads 24, 26 which are insulated with a heat-resistance plastic coating. The leads extend through copper shield tubes 28, 30 which are soldered together at 28 and twisted to reduce inductive pick-up and extend along the top of the pipe. The shield tubes are encased in an insulating sheath 32 of a silicone fibre glass composition which covers them to a point adjacent the electrodes. The leads are connected to an electronic amplifier 38 which may be coupled to a recorder or flow .controller.

Patent GB-1077221-A (GB)
Title: Acoustic direction finder
IPC: G01S3/802
Filed: 1965-06-22
Abstract: 1,077,221. Sound source direction finding. CSF-COMPAGNIE G•N•RALE DE T•LEGRAPHIE SANS FIL. June 22, 1965 [June 26, 1964], No. 26455/65. Heading H4D. A system for determining in which of m predetermined directions a source of acoustic plane waves lies comprises an array of receivers whose outputs are each connected to the input of a respective tapped delay unit, and m groups of q wires (q>1), each group being associated with a different one of the m directions and having a respective adder to the input of which the q wires of the group are connected, each wire of each group being connected to a selected tapping of each delay unit such that the output signal of any adder is a maximum for waves coming from the direction associated with that adder. In the Fig. 2 embodiment, hydrophones 1.1 to 1.n arranged in a curvilinear array (Fig. 1, not shown) are connected to respective tapped delay lines or shift registers 4.1 to 4.n. A pair of wires F<SP>1</SP>#, F<SP>2</SP># (i.e. q=2) link selected tappings to an adder 5# associated with a reference direction #. The invention is essentially a modification of the DIMUS system described on page 867 of the Journal of the Acoustical Society of America, July, 1960, wherein the delays applied to the receiver output signals are such that waves from a direction # would give rise to in-phase signals at tappings linked by a single wire F#, in that the two wires F<SP>1</SP># and F<SP>2</SP># replace the single wire F# of the known system and introduce further phase differences F<SP>1</SP>#-F#, F<SP>2</SP>#-F#, such that the receiver output signals are respectively " under - compensated " and " over - compensated " on the two wires F<SP>1</SP>#, F<SP>2</SP>#. For a monochromatic wave, the sum of the signals appearing at the two wires F<SP>1</SP>#, F<SP>2</SP># is in phase with the signal which would appear at the single wire F#. The amount of under- or overcompensation is progressively greater for receivers towards either end of the array, and is selected such that, for the highest frequency of the incident plane waves, signals from the central receiver in the array arrive in-phase at wires F<SP>1</SP>#, F<SP>2</SP>#, while signals from either of the end receivers of the array arrive in antiphase at the two wires. Signals from the end receivers are thus effectively attenuated with respect to signals from the central receivers, resulting in a broadening of the main lobe of the directivity pattern of the array and a reduction of the side lobes. The broadening effect is diminished for plane wave frequencies lower than the maximum. The invention thus provides compensation for increased directivity of an array with frequency. It is stated that improved compensation, and over a greater frequency bandwidth, may be obtained using more than two wires for each reference direction.

Title: Adjustable speed dynamoelectric apparatus
IPC: H02P5/695
Filed: 1970-06-02
Abstract: 1316321 Automatic speed control H C DE JONG and R D MIDDLEBROOK 2 June 1970 [25 July 1969] 26503/70 Heading G3R [Also in Division H2] A speed control system comprises D.C. machines A, B, having field windings 16a, 16b supplied with constant excitation from fixed brushes 19b, 20b on the machine B, whose shaft is driven at constant speed by a prime mover 40 and is differentially coupled, together with the shaft of the machine A, to an output shaft 12 the speed of which may be varied by adjustment of the position of movable brushes 22b, 23b on the machine B to vary the voltage applied to fixed brushes 19a, 20a on the machine A, whose speed is thereby varied. If the speed of the combination 40, B falls below the preset constant value a servo-amplifier 45, supplied with a reference signal ER representative of this value and the voltage E across the brushes 19b, 20b, produces an error signal which adjusts a throttle 46 controlling the prime mover 40 to restore the speed to the pre-set value. If the speed of the combination rises above the pre-set value due to an overhauling load driving the shaft 12 faster, the error signal from the servo-amplifier 45 is applied to a motor 44 which controls the position of movable brush sets 41a, 42a and 41b, 42b on the machines, each set being connected through a respective resistor 43a, 43b and being normally arranged in a position producing zero voltage across the brushes of each set. Thus an error signal causes the brush sets to be moved to develop a voltage which is applied to the resistors 43a, 43b, the resulting power dissipation therein producing a braking torque which restores the speed of the shaft 12, and hence the speed of the combination, to the pre-set value.

Abstract: 847,923. Fire extinguishers. GRAVINER MANUFACTURING CO. Ltd., and WILKINSON SWORD Ltd. Aug. 29, 1957 [Aug. 31, 1956], No. 26594/56. Class 47. [Also in Group XXVIII] A liquid container of the kind in which pressurized gas effects ejection of the liquid comprises a liquid reservoir having a normally sealed liquid outlet at one end, a gas reservoir having a normally sealed gas outlet located adjacent said end, and electrically ignitible explosive means for unsealing the liquid outlet and substantially simultaneously opening said gas outlet to allow the gas to enter said liquid reservoir and eject the liquid therefrom through said liquid outlet. In a fire-extinguisher, a pressurized gas reservoir 16 having an integrally formed closure plug 16a 1 connected thereto by a thin frangible web 16a 2, is mounted within a liquid reservoir 10 having two discharge orifices 12a, 12b in a discharge head 11, each orifice 12a, 12b, being closed by a stopper member 11a, 11b respectively, each of which is integrally connected to the discharge head 11 by means of frangible webs 11a, 1, 11b1 respectively. A spigot 16a 3 on the plug 16a 1 is coupled by levers 23a, 23b with each of the plugs 11a, 11b. Electronically ignitible explosive charges 13a, 13b are associated, respectively, with the orifices 12a, 12b. On firing one of the charges 13a or 13b, the explosive force acts upon the corresponding stopper 11a or 11b to sever the web 11a or 11b 1 and force the stopper downwards into a cup portion 15a or 15b so that liquid can pass freely out of the corresponding outlet 12a or 12b. The movement of the stopper member 11a or 11b exerts a camming action upon the lower end of the corresponding lever 23a or 23b and this lever then acts upon the spigot 16a 3 to fracture the web 16a 2 of the plug 16a 1, thereby releasing gas from the reservoir 16. The released gas passes upwardly through a tube 19 and then propels a piston 20 towards the discharge head 11 to eject the liquid through the selected orifice 12a or 12b. When the piston 20 reaches the end of its travel, gas behind the piston escapes through ports 16b 1 in an extension 16b of the reservoir 16 to drive out the remaining liquid in the discharge head 11 and in any pipes attached to the orifice 12a or 12b. There may be one, or more than two discharge orifices, associated with a corresponding number of levers coupling the liquid stoppers with the plug 16a1. The gas reservoir 16 may be filled, and its pressure checked, by means of a valve extending through the end wall 10a of the liquid reservoir 10. The levers 23a, 23b, may be modified so that movement of the stopper members 11a, 11b causes inward movement of the plug 16a1. Reference has been directed by the Comptroller to Specification 794,720.
