Filed: 1969-10-06
Abstract: 1278506 Fluid-pressure servomotor systems J M KEMPER and R W WHANN 6 Oct 1969 49036/69 Heading G3P A regulator for controlling the pressure in an enclosure 10 such as an aircraft cabin, comprises a pressure chamber 22 having an inlet 24 and an outlet 25, valve means 26 for one of the passages, an isobaric control 50 and means 68 sensitive to and responsive to pressure in the chamber and also to pressure outside the enclosure to control the valve means 26, enclosure pressure control means 16 governing the flow of air through the enclosure and having a movable control element exposed to enclosure pressure, and means 32 whereby the pressure in chamber 22 is employed to operate the pressure control means 16. The enclosure is supplied by a pump 11 and the pressure within it is determined by the load applied by a spring 55 to a lever 40 on which both the isobaric bellows 50 and the means 68 act to operate the valve 26. Pulses at an adjustable frequency from a unit 118 adjust the spring through a reversible motor 83 and a worm drive 81 until a brush 106 manually set to a position corresponding to the pressure required within the enclosure is positioned adjacent an insulating segment on a commutator disc 93 rotated by the worm gear. In order that this mechanism may not operate while the aircraft is on the ground, a switch 125 is operated by the landing gear 126 while a further switch 137 operated by a diaphragm closed chamber 135 with an aperture 140 to delay pressure equalization prevents operation except when the aircraft is climbing or descending. Both these switches may be by-passed by manually-operable switches 129 and 151. When the upper side of the diaphragm 68 is connected to atmosphere by a valve 62, the diaphragm applies an increasing force opposing that of the spring 55 as the aircraft climbs so that the cabin pressure changes at a slower rate than that of the atmosphere. Rotating the valve 62 to a position in which the upper side of the diaphragm is connected to the enclosure 22 allows the rate of pressure change in the enclosure 22 to be determined by the frequency of the pulses from the unit 118 until the commutator disc breaks the motor circuit at the pre-set pressure value which may correspond with the atmospheric pressure at the airfield where the aircraft is to land. Flow through the chamber 22 is induced by an injector 29 supplied by the engine compressor while the pressure in the chamber is prevented from exceeding ambient pressure by more than a predetermined amount by providing a stop 74 to co-operate with a valve of the kind known by the Trade Mark "Schrader" whenever the valve is lifted by the pressure differential on a diaphragm 72.

Abstract: 1,221,373. Anaesthetic apparatus. O. H. DRAGER [trading as DRAGERWERK, HEINR. & BERNH. DRAGER], 21 Oct., 1968 [21 Oct., 1967], No. 49924/68. Heading AST. An anaesthetic apparatus comprises a liquid anaesthetic evaporation chamber 9 connected in a first conduit 1, 2, 5, 8, 3, 7 and 13, a bypass conduit 2, 4, 6 and 7 bypassing the chamber and a throttle 4 in the bypass conduit for regulating the relative amounts of carrier gas passing through the bypass and chamber and comprising a valve port 4a and throttling member 4b having a connecting member 23 linked by a pin 25 to spindle extension 21, the extension 21 and member 23 having different coeffiients of expansion so that the throttle is controlled by the temperature of the liquid anaesthetic in the chamber. Spindle 15 and extension 21 pass through the throttling member but are not directly attached to it. Manual adjustment of throttle 4 is by thread 19 and knob 18. The coefficients of expansion of spindle extension 21 and connecting member 23 are chosen so that as the temperature of the liquid anaesthetic falls and the vapour pressure falls consequently, the bypass throttle tends to close so that more carrier gas passes through the chamber and maintains constant the concentration of anaesthetic vapour in the carrier gas emanating from 13. A second throttle 3 may be interposed between the chamber 9 and mixing chamber 7 and connected by meshing gear wheels 16 and 17 to the spindle of throttle 4 so that as 18 is turned to close throttle 4, 3 is opened by the same amount and vice versa. The throttle 4 can be adjusted so that it closes at a predetermined temperature in the chamber 9. The temperature of the liquid anaesthetic can be sensed by a stud 26 and read on a dial 24 or the dial 24 can be calibrated to read the percentage of anaesthetic vapour in the mixture once the temperature has fallen and the carrier gas carries the saturation concentration of vapour at the liquid temperature.

Abstract: 1,102,846. Character scanners. INTERNATIONAL BUSINESS MACHINES CORPORATION. 10 Nov., 1966 [17 Dec., 1965], No. 50347/66. Heading G4R. When a scanning beam detects a character on a document, the document is moved in a predetermined direction and the beam controlled so that it remains substantially in the same position relative to the character. A document is scanned in a search raster from the top downwards by a flying-spot scanner until a character is encountered when the document is driven upwards, the scanner beam being deflected upwards by a fixed increment every time the character catches up with it. When in this way the beam reaches the upper limit of the scannable field, as determined by comparing the vertical deflection voltage with a fixed positive voltage in a first voltage discriminator, the document is halted and the top line of character is displayed on a second cathode-ray tube controlled with and from the scanner. The operator now presses a switch to cause the top line of characters to be scanned in a raster to feed character recognition circuitry. The next line below is then searched for and scanned for recognition, and so on to the bottom of the scannable field at which a second voltage discriminator comparing the vertical deflection voltage with a fixed negative voltage causes the document to be driven upward again, the scanner beam " riding " the line reached until it reaches the top when the document is stopped and recognition scanning proceeds as before. If no character were encountered during the initial search for a character, detection by the second voltage discriminator that the bottom of the field had been reached would cause the document to be moved upwards until a line had been detected and " ridden " to the top by the beam. Provided a manual switch is closed, failure to recognize any character during the recognition scans causes the document to be driven upwards until the beam, " riding " the line containing the unrecognized character, reaches the top of the field, when a lamp is flashed and a mark is printed by the line. Then recognition scanning continues from the character reached. The second cathode-ray tube may display the character being scanned at any time, on actuation of a manual switch.
