Filed: 1936-10-20
Abstract: 462,960. Fluid pressure servomotorcontrol systems. HARNDEN, Ltd., C. A., and HARNDEN, C. A. Oct. 20, 1936, No. 28464. [Class 135] Guiding means for a web 4 which is being taken from a roll 3 comprises a piston 12 which is actuated by fluid pressure supplied from pumps 19, 20 to move the spindle 5 carrying the roll in an axial direction to correct any misalignment. The supply of the pressure fluid to the piston 12 is controlled by a valve 17 which is in turn controlled by the degree of suction on a piston 30 in a pneumatic cylinder 31. To actuate the valve 17 a further valve 37 and a piston 38 are provided, a connection 41 being taken to a vacuum pump and a connection 43 to an adjustable box 45 with a port 44 controlled by the edge of the web 4. The piston 38 is provided with a small orifice 40 which provides communication between its two sides and balances the degree of suction when the port 44 is closed by the edge of the web as shown, the piston 38 being in its lowest position, the valve 37 closed, and the piston 30 also in its lowest position. Under these conditions pressure fluid is admitted to the cylinder 11 to move the piston 12 and the roll 3 to the right to uncover the port 44. When the port 44 is uncovered the piston 38 is lifted and the valve 37 opened and suction applied to the piston 30 which is lifted and which actuates the valve 17 to reverse the flow of pressure fluid to the piston 12 and move the roll 3 to the left to cover up the port 44 again. The edge of the web 4 is thus maintained between the sides of the port 44. A valve 16 is provided to byepass the ends of the cylinder 11 when the automatic guiding is not required, as in the initial threading up of the machine.

Patent GB-534498-A (GB)
Title: Improvements in hearing testing appliances or audiometers
IPC: A61B5/12
Filed: 1939-10-27
Abstract: 534,498. Hearing tests. ELECTRICAL RESEARCH PRODUCTS Inc., and BULL, R. A. Oct. 27, 1939, No. 28832. [Class 81 (ii)] A hearing testing apparatus of the type in which the subject to be tested listens to sequences of interrupted sounds or " pips comprises a first switching device 9, such as a brush and segment switch or a cam switch, which can selectively initiate two or more different series of pips, and a second similar switching device 5 which selects various predetermined combinations of pip-series from the first device so as to build up the required pip sequence, the pips being so produced that they rise and decay gradually, thus reducing the generation of spurious signals. In the arrangement shown, the pips are produced by a pentode oscillator 44, which operates in conjunction with circuits tuned by condensers 151 ... 155 to generate frequencies of 250, 500, 1,000, 2,000 or 4,000 cycles per second. The anode supply to the pentode is taken from a half-wave rectifier tube 43, operating in conjunction with resistances and a condenser 56, and passes through the switching devices 5, 9 and through a delay circuit composed of condensers 48, 49 and resistances 51, 52 ; the delay circuit causes the anode potential to rise and fall relatively slowly. The switching device 5 comprises three rings with conducting segments, all the shaded segments being connected together, and the unshaded segments, which are also conducting, being connected together. Voltage is supplied to the switching device 5 through a switch 2 by means of one or other of a pair of brushes a, d, and is taken to switching device 9 through brushes.b, e'or c, f and a switch 1. The device 9 comprises a ring 90 with four conducting segments (shown shaded) and four insulating segments (unshaded), a conducting ring 91, and a ring 92 with three conducting segments and three insulating segments. The device 5 moves through 15 degrees for each revolution of the device 9, and by these means a series of pips is initiated at each selected frequency the pips being divided into groups comprising four series of three or four pips each. Working in conjunction with the switching devices is a potentiometer attenuator operated by switch 3, which is so arranged that each group of pips is produced at a lower level of audibility. The switches 5 and 9 are driven by a motor 60, which also drives a cam operating the switch 3. When the test is completed at one frequency, the switch 2 is operated to select the next frequency, the switch 1 being operated at the same time, so that a different pip sequence is obtained at each frequency. The subjects to be tested listen to the pips in headphone receivers 45, which at the three lowest frequencies are shunted by a condenser 160 through a switch 4 on the same shaft as the switches 1 and 2. This produces a falling frequency response characteristic in the receivers, and prevents harmonics of the testing frequency from reaching an audible level. A switch 69 is provided to stop the motor 60 when one pip-sequence has been completed.

Abstract: 704,107. Gas turbine plant. STANDARD OIL DEVELOPMENT CO. Dec. 14, 1951 [June 30, 1951], No. 29344/51. Class 110 (3). [Also in Group XIII] A combustion process for a gas turbine comprises burning fuel with the theoretical amount of air in the presence of fluidized inert solids to heat same, withdrawing part of said heated solids from the combustion zone and contacting same with either compressed air or compressed recycle turbine exhaust gas and passing a mixture of said combustion gas and the heated compressed gas into the turbine, the solids having been separated from the said mixture or the components thereof and thereafter returned to the combustion zone. An axial-flow compressor 5 supplies air to a combustion chamber 1 through a pipe 6 having a tapping 25, 28 communicating with a cyclone 8, the air being preheated in a heat exchanger 27 by the turbine exhaust gases. The combustion chamber communicates with the cyclone 8 through a pipe 11 or pipes 9 and 28 and has an inlet pipe 3 for solid, gaseous or liquid fuel. When gaseous fuel is used it may be mixed with the air prior to entering the combustion chamber. The'combustion chamber contains solids which are withdrawn through a pipe 12 containing aerating' taps and fed through the pipe 25, 28 to the cyclone 8 from which they are returned to the combustion chamber through a pipe 14 having a tapping 15. The solids are fed to the cyclone by compressed air or by turbine exhaust gases. Again the solids may be entrained in the combustion gases and fed to the cyclone. The exhaust gases from the turbine 18 are sucked by a compressor 23 through pipes 19 and 22 having tapping 21 and a water spray cooler 29 therein and recirculated through the pipe 24. In a modification the solids are fed to a heat exchange vessel, instead of the cyclone 8 and are returned to the combustion chamber through a pipe having aerating and withdrawal taps therein. The gases leaving the combustion chamber and the vessel are cleaned in cyclones disposed in the outlets of these members 'respectively and are then fed to the turbine 18. The heat exchanger 27 may be replaced by two vessels in which solids are circulated, the solids being heated by exhaust gases in one vessel and cooled by air in the other vessel. Methane, ethane, natural gas, Diesel oil, bunker fuel oil or powdered coal is burnt in the combustion chamber. Specification 678,674 is referred to.
