Title: A lung ventilator
IPC: A61M16/00
Filed: 1968-08-01
Abstract: 1,241,830. Respiratory appliances. JARNHS ELEKTRISKA A.B. 1 Aug., 1968 [2 Aug., 1967], No. 36863/68. Heading A5T. A lung ventilator comprises a respiratory circuit means 1 for supplying respiratory gas under pressure and means 11 for discharging exhaled gas, inspiration and expiration lines 2, 5 for connection to a patient's breathing organs 3, and automatic flow regulators 4, 6 in the lines to keep the flow rates at a constant level, and incorporating solenoids 7, 8, to close the valve members 4', 6' of the regulators when energized. Flow regulators 4, 6 are as described in Specification 1,214,933 and each consists of valve member 4' 6' actuated by a flow rate responsive differential pressure appearing over a constriction 4" to throttle the flow in the passage if said pressure difference exceeds a certain value, thus providing a constant volume flow. The switching between inspiration and expiration phases is achieved by solenoids 7, 8 which when energized, shut off the flow in their respective lines completely, and are connected to an electronic, preferably transistorized, unit 9. This incorporates astable and monostable multivibrators of adjustable pulse frequency and duration, and an AND gate, to provide variable inspiration and expiration times, and a rest period between the two, also of variable length, when both valves 4, 6 are closed. A pressure transducer 10 in the expiration line supplies a signal to control unit 9 if the pressure rises above or falls below critical values. This may be used to allow the patient to control the ventilator by his own breathing activity. At predetermined intervals an extralong inspiration and expiration period may be provided by control unit 9. The control unit 9 may be connected to optical or sound indicating means to indicate when the pressure is above or below the critical valves. Source 1 is an over-pressure source such as a motor driven pump or reservoir. A sub-pressure source 11 may be connected to connection line 5 to facilitate emptying of the patient's lungs.

Title: Automatic railway car coupling
IPC: B61G1/16
Filed: 1930-12-08
Abstract: 353,366. Automatic couplings and draw-gear for railway vehicles. STIEGER, J. UNTERN€HRER-, Erlenbach, Zurich, Switzerland. Dec. 8, 1930, No. 36935. [Class 103 (v).] In an automatic coupling for railway vehicles of the kind in which a pivoted linkage or bolt 19 on each vehicle rides up the inclined face of a hook 11 and then drops into coupling engagement, where it is held by means of weighted levers 25 at the ends of a transverse shaft 23, locking means are provided for retaining the weighted levers in their effective position, while the connection between the shaft 23 and the lifting member that effects the uncoupling is such as to permit an initial idle movement of the shaft, thus allowing the lifter to be given a vigorous blow in case the bolt should display considerable frictional resistance to being raised. The locking means for the levers 25 comprises a pair of slidable transverse rods 30 pivoted at their inner ends to a common double-armed lever 32 and at their outer ends each adapted to engage within a slot 27 on a collar 26 fixed to the shaft 23. A second slot 28 is provided on each collar 26, with which the end of the corresponding rod 30 may be engaged for holding the coupling bolts 19 and levers 25 permanently in a raised position, e.g. for shunting purposes. Prior either to coupling or uncoupling the rods 30 must be pushed inwardly by the terminal handles 31 so as to free them from engagement with the collars 26. The coupling element consists of a transverse bolt 19 secured to the ends of a pair of links 18 pivoted on a bolt 12 mounted on the shank I of the coupling hook, while the lifting member comprises a second pair of links 13 pivoted on the bolt 12 and supporting a depending frame 14, Fig. 3, which is fitted with upper and lower sets of rollers 16, 17 adapted to push the coupling element 19 downwards or upwards. An operating link 22 extends from the shaft 23 to embrace with a lost-motion connection a depending pin 20 on the frame 14, so that, when the levers 25 are manually raised to uncouple the vehicles, the initial movement is unopposed by the friction between the coupling members. Each hook shank 1 is pivoted at 5 to a draw-bar 6 so as to be displaceable towards one side of the vehicle and is centralized by springs 10, while a spring 9 on each vehicle absorbs buffing shocks in coupling.

Abstract: 435,727. Carburetted water gas. SEMET-SOLVAY ENGINEERING CORPORATION, 61, Broadway, New York, U.S.A. (Assignees of Oliveros, R. P. ; 180, Lenox Road, Brooklyn, New York, U.S.A.) Dec. 28, 1934, No. 37190. Convention date, Jan. 5. [Class 55 (i)] In a process of making carburetted water gas by the passage of oil and steam through an incandescent fuel bed, the backrun or down-run is divided into two portions, in the first of which all or most of the oil and a small portion of the steam is passed through the fuel bed, and in the second the greater part of the steam is passed through, and little if any oil. The apparatus comprises a generator 1, carburetter 2, superheater 3, and washbox 4. The upper part of the generator communicates with a dust catcher 6, and the base of the carburetter and superheater are connected by a duct 7. The gas offtake 9 leads through a three-way valve 11 to the washbox and to a back-run pipe 12 leading to the base of the generator. The generator is provided with oil and steam inlets 16, steam inlets 37, 38, and air inlet 39, and the carburetter has water cooled oil and steam nozzles 29, secondary air inlets 45 being provided, and air inlets 33 at the bottom of the carburetter. A back-run steam jet 36 leads into the top of the superheater, and a down-run steam jet 37 to above the fuel bed. In operation, after an air blast, and burning of the resultant gases in the carburetter and superheater, an up-run with steam from inlet 38 is made and the water gas carburetted with oil from nozzles 29, the vapours and gases passing through the superheater to the outlet 13. During the two minute back-run with steam from inlet 36, in the first 63 seconds 60 lbs. of steam are passed and 15 gallons of oil from nozzles 16 are passed through the fuel bed, and in the last 57 seconds 175 lb. of steam are passed, when using a generator of 11 feet diameter.

Title: Improvement in phthalic anhydride recovery
IPC: F02M29/02
Filed: 1934-12-31
Abstract: <PICT:0449621/IV/1> Phthalic anhydride is recovered from gases or vapours containing it by passing the gases or vapours in a turbulent stream through a cooled tubular condenser.  The process is particularly useful in recovering phthalic anhydride from the catalytic vapour-phase partial oxidation products of naphthalene or methylnaphthalene. As shown, air is passed through a pipe 3 into molten naphthalene in a vessel 1, and the mixture of air and naphthalene vapour is led into a catalytic apparatus 5 of known type; additional air may be supplied by a pipe 6.  The reaction products are cooled in a cooler 8 to a temperature slightly above the dew point of phthalic anhydride and are then passed to a cooled tubular condenser 10 through which they flow as a turbulent stream.  The condenser 10 is fitted with a screw conveyer 13 which scrapes the walls of the condenser and delivers the condensed phthalic anhydride through a valve 23 into a collecting vessel.  To avoid clogging the condenser at the inlet end, the conveyer shaft 15 is abbeviated in the manner shown.  The gases from the condenser pass to a two-part bag filter 18 of known type in which any phthalic anhydride dust entrained in the gases is separated; the bags are shaken periodically by mechanism 19<a>, and their contents are carried by a conveyer 22 through the valve 23 to the collecting vessel.

Filed: 1954-12-31
Abstract: 781,785. Automatic control systems. PHILIPS ELECTRICAL INDUSTRIES, Ltd. Dec. 31, 1954 [Jan. 4, 1954], No. 37827/54. Class 38 (4). In an automatic control system of the kind in which deviations are detected by a selfbalancing bridge, the resetting of which applies a signal to an amplifier controlling a reversible servo-motor to correct the detected deviations, a common amplifier is used for both the bridge resetting circuit and the servo-motor with intermittent switching from one circuit to the other. An A.C. bridge 2, 3, 4, Fig. 2, having a variable element 3 is self-balancing via amplifier 6 and motor 7, and controls a potentiometer 8 applying a control signal to servomotor 12 correcting the variable, via amplifier 6 when the switches 19, 20 occupy their lower position. This position is occupied for one second per minute and the control is thus in accordance with the integrated error. The switches 19, 20 have unspecified actuators. In a modification, Fig. 3, proportional plus integral control is obtained by controlling potentiometer 8 in accordance with bridge balance as above, but using the motor 12 not to correct the variable-but to change the balance of a second A.C. bridge 23. The variable is corrected by a third motor 27 and an auxiliary amplifier 26 energized in accordance with the proportional error voltage from potentiometer 8, plus the integrated error voltage from bridge 23. Follow-up from the motor 27 to bridge 23 is provided. It is stated that a single motor with mechanical change-over can replace the two motors of Fig. 2.
