Title: Method and apparatus for testing a device through which a fluid is passed
IPC: G01F1/34
Filed: 1974-03-06
Abstract: 1456572 Testing spray carburetters KARL WEISS-GIESSEN FABRIK ELEKTROPHYSIKALISCHER GERATE WERK LINDENSTRUTH 6 March 1974 [8 March 1973] 10100/74 Heading F1H A device through which a fluid passes is tested by imposing a predetermined constant flow of fluid through it, measuring the pressure prevailing at the inlet of the device, the pressure at the outlet being substantially constant, comparing the measured value with a set value which is prescribed for the predetermined flow, and actuating adjustment means of the device until the measured value is substantially equal to the set value. A carburetter I, Fig. 1, under test is put into a chamber 3 and subjected to a predetermined constant flow via inlet and discharge lines 4, 5. The pressure upstream of the carburetter is measured via a line 16 by a transducer 16 and displayed on a pressure gauge 17, the resultant signal being applied via a line 18 to a differential amplifier 19 which also receives a reference signal representing a set value of the pressure from a signal generator 21 via a line 20. The resultant difference signal at the amplifier output 22 is fed to a motor 23 which positions the carburetter butterfly valve 2 to eliminate the difference, the resultant angular position of the valve being displayed by an indicator 24. The flow through the carburetter is created by a vacuum pump 6 in the discharge line 5, the means for maintaining the flow at a constant value comprising a choked nozzle 11 or 12 in the inlet line 4, the pressure upstream of the nozzle being rendered constant by a control system 10 and the pressure downstream of the carburetter being rendered constant by a choked nozzle 53. Valves 13, 14 enable either of the nozzles 11, 12 to be brought into use, whereby two different predetermined constant values of the flow can be chosen. Compensation for the augmentation of flow provided by the fuel introduced into the air in the carburetter can be afforded by a by-pass 55, containing a choked nozzle 54. The fuel temperature may be maintained constant by means of a heat exchanger. As shown in Fig. 2, the control system 10 may comprise a by-pass duct 36, 39 through which a portion of the flow is diverted from the nozzle 11 or 12 under the control of a valve 37 or a choked nozzle. A second chamber 25 containing a second carburetter under test is provided in parallel with the chamber 3, valves 42, 43 permitting the flow to be cut off from either chamber. To avoid variations of flow caused by variations of temperature, heat exchangers 35, 44 are provided to maintain constant temperature upstream and downstream of the nozzles 11, 12. The air directed through the by-pass 36, 39, which is at the constant temperature maintained by the heat exchanger 35, passes through jackets 38, 40 to protect the nozzles 11, 12 and chambers 3, 25 from temperature variations. The heat exchangers may contain means for de-humidifying the air. The device may be used for testing air-flow meters for electronic fuel injection systems.

Abstract: 943,322. Tumbler and spin driers. WHIRLPOOL CORPORATION. March 16, 1962 [March 23, 1961], No. 10218/62. Heading F4G. [Also in Division D1] Apparatus, e.g. a coin-operated laundering machine, has a rotatable member 30 and a switch 43a sensitive to its rotation, the switch 43a controlling signal means, to monitor the rotation of the member 30. A pulley 30 fixed to the shaft 13 of the clothes drum of a timercontrolled dry-cleaning machine and driven by a belt 31 has blades 46 clipped on its spokes 47. The air currents produced by the blades 46 are sufficient at high rotation speeds to deflect a vane 45 and close a spring-biased microswitch 43a. During low-speed parts of the cycle and during the last minute of spin-drying, a switch is kept closed by a timer cam to supply power to the cam-shaft motor and to a solenoid holding open a switch in the power line of the signal means. Shortly after the change to high speed drive for spin-drying, the cam opens its switch but if the pulley 30 is rotating at the required high speed, the microswitch 43a is closed thereby completing another power supply line to the motor and solenoid. If the drive to the clothes drum is not working properly, the switch 43a will still be open and the cam-shaft motor and the solenoid will be de-energized thereby stopping the cycle of operation and actuating the (audible or visual) signal means. A conventional blower 18 is provided for hot-air drying.
