Patent GB-894094-A (GB)
Title: Apparatus for controlling or assisting respiration
Inventor: BAXTER IAN GEORGE
IPC: A61M16/00
Filed: 1960-02-03
Abstract: 894,094. Respiratory appliances. BRITISH OXYGEN CO. Ltd. Feb. 3, 1961 [Feb. 3, 1960], No. 3823/60. Class 81 (2). In a forced breathing respirator the supply valve is controlled by a pressure-responsive member which is actuated by a flow-meter in accordance with the volume of gas passed to the patient. The control-valve assembly comprises a pivoted member 7 mounted so that it can close either valve 29 or 3 according to its position and it is actuated by a bellows 9, the movable end of which carries a magnet 11. When the bellows is collapsed this magnet approaches the member 7 and attracts it, so that valve 29 is closed, but when the bellows is distended, a fixed magnet 10 predominates and the member 7 is tilted to close valve 3. Gas enters a chamber 2 through a tube 1 and thence passes through valve 3 to an injector 4, where it entrains air, and then flows through a resistance element 16 to the patient. The pressure drop across the element 16 is communicated to a diaphragm 21, dividing two chambers 19, 20, which is consequently moved towards the right at a rate depending on the setting of a needle valve 22. At the end of this movement a plunger 23 engages a valve 24 which allows gas from the supply to pass to the interior of the bellows 9 and cause this to distend until the member 7 moves over to its alternative position. The supply to the patient is thus cut off and his lungs collapse naturally while a flow of gas through pipe 28 opens a valve 27 and extracts the gas from chamber 19. This restores the diaphragm 21 to its original position while, with valve 24 now closed, the contents of the bellows escape through an adjustable valve 13. The bellows collapse slowly under the pressure of a spring 14 until the original conditions are restored. Since the rate of movement of the diaphragm 21 is constant for any given setting of the valve 22 the time during which inspiration is continued depends on the volume of gas passed to the patient. The duration of exhalation is determined by the setting of the valve 13.

Title: Improvements in or relating to regulators
IPC: G05D16/20
Filed: 1928-02-07
Abstract: 286,640. Smoot Engineering Corporation, (Assignees of Smoot, C. H.). March 7, 1927, [Convention date]. Electrically-actuated valves. - A regulating apparatus comprising a power means adapted to control an element upon. an unbalance between a regulating force and a force varying as a function of the controlled element is associated with an electrical device for creating a gradually increasing resilient force tending to stop said power means and itself from functioning, and another device, actuated when said resilient force reaches a definite value, tending to reduce said force. The Figure shows the application of the device to the control of a fluid pressure. The butterfly valve 1 is actuated by a reversible electric motor 3 acting through a worm 5 and toothed quadrant 4 and controlled by a two-way switch 9, 10, 11 actuated by conduit pressure acting on a liquid sealed bell 15 hung from a weighted lever 13. The anti-hunting device comprises a pair of springs 22 arranged between the end of the lever 13 and a pair of arms 21 on a spindle 17 reciprocated in fixed guides 18 by two reversible electric motors 32, 37. The motor 32 which is connected in parallel with the motor 3 acts through bevel gears 30, 31 to rotate a member 28 rotatably mounted in a fixed bucket and having a screw-threaded engagement with a rod 20 connected to the spindle 17. The motor 37 acts through a similar gear but having a larger reduction ratio and having a splined instead of a screw-threaded engagement with the rod 20. The motor 37 is controlled by a two-way switch 23, 25, 26 actuated by the movement of the rod 17. The motor 37 is only started after the motor 32 has moved the rod 17 a predetermined distance to tension the springs in the direction required to open the sitch 9, 10, 11, but continues rotation after the motors 3 and 32 have been stopped to reduce the tensioning of the springs. A single motor mav replace motors 3 and 32. In a. modification, the ends of the springs are secured to fixed abutments and the contacts 9, 10 are mounted on the rod 17.

Filed: 1950-02-16
Abstract: 704,749. Automatic exchange systems. SIEMENS & HALSKE AKT.-GES. Feb. 16, 1950 [Feb. 16, 1949 ; July 25, 1949], No. 4039/50. Drawings to Specification. Class 40 (4)  In a system in which metering impulses may have to be sent over a junction while conversation is taking place, e.g. where metering according to the duration of the call takes place, the impulses are sent over the line wires in series, arrangements being made to prevent interference between the speech and metering circuits. This arrangement enables phantom circuits to be operated over the junctions. In one arrangement series D.C. impulses are provided by an A.C. source feeding a full-wave rectifier arrangement connected in series between the two halves of the split secondary winding of the line transformer, the A.C. being applied by a transformer enabled by the connection of D.C. to an additional winding by the metering contact. In a second arrangement the pulses are produced by the inductive kicks in the secondary of a transformer whose primary is pulsed with D.C., the secondary being connected across the line and reception being effected by a polarized relay similarly connected. Interaction between speech and metering circuits is prevented by the use of suitable tuned circuits. In a third arrangement A.C. is applied across the line and received by a full wave rectifier feeding a relay, with timed circuits utilized as in the previous arrangement. In a fourth arrangement A.C. metering impulses are applied and detected on the office side of the line transformers, high pass filters being used to prevent the A.C. passing into the speech circuit and the A.C. being fed to line via a low pass filter, to remove harmonics therefrom.

Patent GB-843340-A (GB)
Title: Improvements in or relating to circuit arrangements for the image-deflection and line-deflection coils of at least two cathode-ray tubes
IPC: H04N9/28
Filed: 1959-02-05
Abstract: 843,340. Cathode-ray tube circuits. PHILIPS ELECTRICAL INDUSTRIES Ltd. Feb. 5, 1959 [Feb. 8, 1958], No. 4114/59. Class 40(7). In a bridge circuit for the deflection coils of a system of cathode-ray tubes whose axes intersect at one point and some of whose axes are in the same plane, the distortion due to the non- parallelism of the axes is corrected by feeding one of the bridge diagonals with a correcting signal. For a system of three projection tubes, 1, 2, 3, Fig. 1, the image appearing on a screen perpendicular to the axis b and situated at P will be formed of three images 4, 5, 6, Fig. 2, and contains linear and trapezoid distortion. If, in Fig. 2, the line deflection is horizontal and the frame deflection vertical, linear correction may be obtained by feeding a parabolic current, Fig. 4 (not shown), to the line deflection coils, and trapezoid correction by feeding a current as in Fig. 5 (not shown) to the frame deflection coils. In a bridge circuit according to the invention for trapezoid correction the frame coils 11, 22, 33 of the tubes 1, 2, 3, are connected as shown in Fig. 6, impedances 7, 8, 9 being equal in value and the coils 11, 22, 33 being assumed to be equal in impedance. Frame deflection currents from a source 30 feed all three coils equally. The trapezoid correction signal source 31 is connected to the other diagonal and feeds current to coils 11 and 33 but not to coil 22. As the circuit is a bridge the sources 30 and 31 have no effect on each other. A similar circuit is used in connection with the line coils to correct for linear distortion. In a practical arrangement of Fig. 6, Fig. 8 (not shown) the sources 30, 31 are coupled to the bridge through transformers. Where four tubes are used, any two being in the plane of symmetry of the other two, the circuit of Fig. 10 (not shown) may be used. In this circuit the diagonal 23-10, Fig. 6, is formed by a second bridge circuit having two of its interconnected arms made up of the frame coils of the two tubes not used in the main bridge circuit. A linear correction signal source is connected in the remaining diagonal of the second bridge.
