Title: Improvements in distributors for automatic artificial respiration apparatus
IPC: A61M16/00
Filed: 1954-06-09
Abstract: 761,480. Artificial respiration appliances. SPIROTECHNIQUE. June 9, 1954 [June 12, 1953], No. 16964/54. Class 81(2) A distributer for automatic artificial respiration apparatus having a first chamber communicating with the atmosphere through a controlled orifice and a second chamber communicating with the respiratory tracts of the patient and a source of breathable gas through a valve operated by a diaphragm which constitutes a wall common to both chambers, the diaphragm being subjected to the thrust of a spring acting in the direction of opening of the valve, is characterized by the provision of an adjustable valve between the second chamber and the respiratory tracts of the patient and an expiration valve provided on an expiration pipe, the expiration valve opening for the beginning of an expiration phase when the gas pressure in the respiratory tracts of the patient reaches a predetermined value relative to the gas pressure in the second chamber. The distributer comprises two chambers 1, 2 separated by a diaphragm 3 to which a thrust is applied by a spring 15 in the chamber 1 which is open to the atmosphere through an adjustable needle valve 5. A pressure regulator adjacent the distributer comprises two chambers separated by a second diaphragm 11, one chamber being in communication with the atmosphere and housing a spring 12 controlling the second diaphragm 11. A source of gas under pressure is connected to a pipe 13 so that gas flows at constant pressure into the other chamber 14 of the regulator through an inlet valve under the control of the second diaphragm 11 with which it is associated. A valve 9 controls an opening 8 between the other chamber 14 of the regulator and the chamber 2 of the distributer. A duct 6 is connected with a face mask 20, Fig. 2, and is provided with an adjustable cock 7. The face mask 20 is also provided with an exhalation duct 21 provided with an cutlet valve 22 under the control of the gas pressure in the chamber 2. With valve 9 open gas passes into the regulator chamber 14 and the distributer chamber 2 and is kept at constant pressure by the control of the second diaphragm 11 over the inlet valve. Gas then passes to the lungs through the duct 6. As gas flows from the pressure regulator to the chamber 2 of the distributer the pressure in the chamber 2 rises the first diaphragm 3 moves against the spring 15 and causes a blade 16 connected with it and with the valve 9 to move so that the opening 8 is closed and the outlet valve 22 of the mask 20 remains closed. The pressure in the chamber 2 subsequently falls so that valve 22 of the mask 20 opens and gas is exhaled through it by the patient. Finally the pressure in the chamber 2 falls sufficiently for the first diaphragm 3 to move towards the interior of chamber 2 so that the valve 9 again opens and the cycle of operations is repeated.

Abstract: 990, 214. Electric control systems. DANMARINE (DANAVIA A. S) A.S. April 30, 1963 [May 7, 1962], No. 16978/63. Heading G1N. An arrangement for producing an electrical signal, dependent upon the angular position of a compass magnet 1, comprises four identical coils 2, 3, 4, 5 arranged on a plurality of rectangular hysteresis loop magnetic cores 6, 7, 8, 9 outside the compass bowl, the coils being connected in a bridge circuit comprising a pair of input terminals 12, 13, fed with A.C., and a pair of output terminals 14, 15, the coils being symmetrical in pairs relative to the axis 18 of rotation of magnet 1, and the axes of the coils lying in a plane perpendicular to axis 18. The output may be applied to steering gear 17. Preferably the bridge is balanced when the axes of the coils lie at 45 degrees to the N-S direction of magnet 1: If device 17 responds to the second harmonic of the supply voltage the winding directions of the coils may be selected so that the second harmonic voltage is zero at the 0 degrees position. The coils and cores are mounted on a support which is rotatable about axis 18 through an operating member, preferably through reversing gearing. It is stated that the output at 14,15 is unaffected by tilting of the compass card due to heeling of the ship. A capacitor 20 may be used to make the output signal substantially sinusoidal.

Abstract: 1,075,885. Laying off tangents. EUROPEAN ATOMIC ENERGY COMMUNITY (EURATOM). April 22, 1965 [April 24, 1964; Jan. 15, 1965], No. 17076/65. Heading B6P. [Also in Division G1] An instrument for measuring the tangent of the angle of slope of a curve at any point comprises a pair of transparent circular rods 1 mounted on a rectangular transparent plate 2 marked with a semicircle 3 which is graduated from 0 to infinity. A cursor 6 is slidably mounted on the rods 1. The instrument is placed on the plane surface containing the curve, at a particular point (O Fig. 2) and rotated about the point O until the curve (A-B) is seen to be not distorted (Fig. 3). The rods 1 are then normal to the tangent at the point O. With the cursor 6 held against the plane surface, the rods are moved parallel to their longitudinal axis until the plate 2 crosses the abscissa and the abscissa intersects the graduated semicircle at the point (C, Fig. 4). Where the abscissa again crosses the semicircle (3) at the point (E), the value indicated at this point E is equal to the tangent of the angle formed between the tangent to the curve at point O and the abscissa. The rods 1 may be mounted in a groove (8) in the plate (2, Fig. 6) or in an aperture (9) in the plate (2, Fig. 7). In a further embodiment (Figs. 8 and 9) the rods are mounted in a recess (13) in a transparent disc (11) rotatably mounted in a circular recess (12) in a base plate 2. The disc is provided with graduations around its perimeter and the tangent value is read off with a cursor (16) slidably mounted on the base plate, which cursor is initially placed parallel to the abscissa.

Title: Regulated power supply
IPC: G05F1/44
Filed: 1971-05-26
Abstract: 1315872 Automatic voltage control INTERNATIONAL BUSINESS MACHINES CORP 26 May 1971 [30 June 1970] 17102/71 Heading G3R A DC - DC converter providing a stablized output voltage at terminal 50 comprises pushpull driver transistors 26, 27 controlled by NAND gates 23, 24 whose inputs receive phaseopposed signals from a control signal source 22 and variable-width pulse signals from a comparator circuit 10 supplied with the output voltage 50 and a reference voltage 41, an inter-stage transformer 28 whose primary windings N1, N2 receive a regulated DC control voltage according to the switching state of transistors 26, 27 and whose secondary windings N4, N5 and positive feedback windings N3, N6 control the switching state of power transistors 30, 31, and an output transformer 32 whose primary winding receives an unregulated DC voltage according to the state of transistors 30, 31 and whose secondary winding supplies a rectifier and output filter 16 connected to terminal 50. A differential amplifier 40 receives the actual and reference voltages 50, 41 and supplies an error signal to one input of a comparator 42 whose other input receives a fixed frequency and amplitude triangular waveform signal from an oscillator 39, such that the comparator output comprises pulses whose width is determined by the error signal. Each gate 23, 24 is switched on, to switch off its driver transistor 26, 27 by virtue of its negative output, when its inputs simultaneously receive a positive signal from the source 22 and an output signal from the comparator 42. Alternate energization of the windings N1, N2 of the transformer 28 (which operates as a current transformer) causes the appropriate transistor 30, 31 to be turned on by the corresponding secondary winding N4, N5, the turns ratio N3/N4 and N6/N5 being made equal to the ratio Ib/Ic of the respective transistor 30, 31 so that the inverse current gain of the transistor remains fixed in the saturated mode, which is produced by the assisting action of the winding N3 or N6 on the winding N4 or N5. During the "dwell" periods of the output signal from the comparator 42 both transistors 26, 27 are switched on and the winding N1, N2 act as a low impedance "sink" for the magnetically coupled current in the winding N3 or N6 depending on which transistor 30, 31 is turning off. In the event of failure of a circuit component, the output voltage is regulated at a predetermined value higher than that set by the reference voltage 41. This is achieved by a circuit comprising members 34, 35, 36, the arrangement being such that a failure causing the output voltage to rise above the breakdown value of the Zener diode 34 produces switch-on of the normally non-conductive transistor 36 to by-pass the windings N1, N2 with respect to the regulated control voltage until the output voltage falls below the breakdown value. The subsequent on/off action of the transistor 36 produces regulation at a value set by the Zener diode 34. Operation of the converter under normal and fault conditions is described, Figures 2 and 3 (not shown).
