Title: Improvements in apparatus for generating a flow of gaseous working fluid for a primemover
Inventor: WELCH DOUGLAS FRANCIS
IPC: F02C7/277
Filed: 1954-01-18
Abstract: 784,121. Generating combustion products under pressure. BRITISH THOMSON-HOUSTON CO., Ltd. Dec. 16, 1954 [Jan. 18, 1954], No. 1463/54. Class 51 (1). [Also in Group XXVI] A combustion chamber in which a monofuel is decomposed to form a gaseous working medium for a prime mover and in which the pressure required for the initial fuel injection and the heat necessary for starting the decomposition of the monofuel are obtained from the burning of a deflagrant, has a pressure intensifier connected to the combustion chamber the increased pressure from which is used for at least the initial fuel injection. The combustion chamber 10 which supplies working fluid to a turbine 11 is supplied with monofuel from a reservoir 12 through a filter 13, non- return valve 14, control valve 15 and non- return valve 16. The pressure developed in the chamber 10 is applied through a conduit 17 on to the larger piston of a pressure intensifier 18. The smaller piston is connected to the fuel supply line 19 between the non-return valve 14 and control valve 15. On closing the switch 21, the control valve 15 is opened and a charge of deflagrant such as cordite in the container 20 is ignited. Some of the heated gases from the deflagrant pass to the pressure intensifier 18 which causes monofuel to be injected into the chamber 10 where it is ignited by the remainder of the gases from the deflagrant. Thereafter the pressure produced in the chamber 10 produces the flow of fuel by way of the pressure intensifier 18. A centrifugal switch 23 driven by the turbine 11 shuts off the valve 15 when a predetermined speed is reached. When the apparatus is used as a turbine driven starter, the speed of the starter is generally indicative that the machine being started is fully operative. The pressure intensifier 18 may be provided with a spring to return the pistons to their initial positon. The container 20 and reservoir 12 may be provided with sufficient cartridges and fuel respectively for a number of operations of the starter. Specifications 726,897, 749,920 and 778,361 are referred to.

Abstract: 1,130,442. Automatic frequency control systems; audio transducers, local circuits &c. UNION SPECIAL MACHINE CO. 13 Jan., 1966 [13 Jan., 1965], No. 1566/66. Headings H3A and H4J. [Also in Division G3] Automatic frequency control.-An oscillator 30 of the Hartley type for supplying operating current to an ultrasonic seaming tool comprises an oscillator valve 46 and a tank circuit 45 which includes a series of tuning capacitors 50 associated with a switch 51 for selecting a desired output frequency. The oscillator output is fed to the tool 10 (Fig. 1, not shown) over a line 73, and to a cathode follower 68 which produces an output across resistor 72, which is in phase with the oscillator output. A phase discriminator 40 includes a transformer 135 having a primary winding 136 supplied with a signal in phase with the current applied to the tool; this signal is compared in phase with the signal across resistor 72, the comparison circuit including the secondary winding 140 of transformer 135, resistors 157 and 158, and a pentode 165 which is effectively connected in parallel with the tank circuit 45 of the oscillator 30. The arrangement is such that any phase difference between the signals under comparison produces an output across resistors 157, 158, which output is applied to the control grid 164 of pentode 165 whereby the effective reactance of the tank circuit 45 is varied in a sense to adjust the oscillator output frequency until the signals are again in phase. By this means, the oscillator output frequency is made to conform with changes in the natural resonant frequency of the seaming tool, which changes are caused by variation in the load on the tool. Audio transducers.-An ultrasonic seaming tool 11 having a flat face 14 for co-operation with a fixed jaw 12 is supported by an annular plate 18 and includes a transducer 10, e.g. a piezoelectric crystal which is bonded to one end of the tool and which is supplied, by way of connections 22, 23, with alternating current of ultrasonic frequency, whereby the tool is caused to vibrate at its natural resonant frequency, the material to be joined being inserted between the jaw 12 and the face 14. A control circuit for maintaining constant the amplitude of vibration of the tool is described with reference to Figs. 1 and 2 (not shown).

Abstract: 1525333 Arc furnace S E STENKVIST 21 Jan 1976 [27 Jan 1975] 02274/76 Heading H5H Wear on the furnace lining of a three-phase arc furnace is equalized by utilizing an electromagnet 8 below the furnace lining 4 to produce a symmetrical magnetic field intersecting the arcs 9 of the electrodes 1, 2, 3, the polarity of the magnet 8 being maintained unchanged for a period substantially exceeding the time period of one complete cycle of the electrode supply current. The field of coil 8 interacts with the rotating magnetic field produced by the arc current so that instead of a single hot spot in the furnace lining adjacent each electrode, two hot spots 12 displaced by 45 degrees relative to the conventional single hot spot, are produced per electrode. By energizing the coil 8 intermittently or with a low frequency A.C. (less than the electrode supply frequency) the wear may be evened out on the lining between each pair of hot spots. The coil may be suspended from the furnace bottom by three magnetic yokes and it may have a core. The furnace bottom must be non- magnetic adjacent the coil when the coil 8 is beneath the furnace shell 6 but should the coil be mounted between the shell 6 and the lining 4 the bottom may be magnetic. The coil 8 may be a pancake coil provided with radial yokes. Separate coils may be placed around the suspending magnetic yokes.

Filed: 1971-01-18
Abstract: 1333874 Acoustic interferometer AUTOMATIC SWITCH CO 18 Jan 1971 [16 Feb 1970] 2296/71 Heading H4D A change in density of a medium is sensed by providing two sets of coherent acoustical waves such that the acoustic radiation associated with one set passes through the medium then interferes with the other set to establish interference fringes, and detecting with a fluidic sensor a shift in the position of at least one fringe in response to the change in density. lt is stated that the medium may be solid, liquid or gaseous. In the Fig. 1 embodiment for detecting temperature-dependent density changes of a volume 21a of gas, acoustical waves are conducted from whistle 20 through conduits 13, 14 to ports 11, 12 in a wall 10 and set up interference fringes 60-66. Acoustically sensitive receiver 30 (a fluidic, turbulence type amplifier) is initially positioned by mechanism 32 such that at some reference temperature the receiver entry aperture 34 is aligned with a fringe. A subsequent temperature change, e.g. due to use of a heat source 22, shifts the fringe pattern and the extent of the shift can be read from scale 33 when aperture 34 is re-aligned with the fringe. The output of receiver 30 may be used as a feedback signal to control heat source 22 or a servo mechanism. In the Fig. 2 modification for detecting density changes of a gas or gas mixture the gas or mixture is passed through chamber 21 via ports 70, 71 and the chamber is provided with diaphragms 72, 73 for the passage of acoustical waves. Other applications of the invention are flow and velocity metering. The whistle 20 and receiver 30 may be fluidic devices as described in Specification 1,270,128 (see Divisions H3-H5 and G4-G6).

Abstract: 752,566. Pulse storage circuits. INTERNATIONAL BUSINESS MACHINES CORPORATION. Jan. 26, 1954 [Jan. 29, 1953], No. 2334/54. Class 40 (6). [Also in Group XIX] A system for storage of differentially timed character-representing electrical impulses comprises a matrix of two electrode gas discharge tubes. The storage system shown for receiving a number from a punched record card 10 (which number may be later read out repeatedly, e.g. in a calculation process such as multiplication by repeated addition), comprises a matrix of elements each consisting of a gas-filled switch tube S and a storage tube T, the columns corresponding to decimal denominations and the rows to different digits. As the card is fed by rollers 11, digit-representing differentially timed positive impulses are supplied from sensing brushes 12 to respective column lines A, B ... N. A capacity-coupled distributer 25, including a condenser element 26 rotated in synchronism with the card feed rollers, supplies the output of an r.f. oscillator 27 in turn to the row lines 9, 8, 7 ... 0 connected to external electrodes d of the tubes S. This r.f. energy produces an auxiliary r.f. discharge which ionizes the gas filling in the tubes and allows flow of low voltage direct current between internal electrodes a, b. Thus that tube T in each column which corresponds to the digit recorded in the corresponding column of the card is fixed, the potential supplied by source 20 through reset switch 21 being sufficient to maintain conduction in the tube after the associated switching tube is extinguished. For read-out, switch 28 is closed to cause a further series of switching tubes OA, OB ... ON to connect lines A, B ... N to output lines Oa, Ob ... On, the distributer-controlled tubes S operating to sense the tubes T in a column in turn so that a differentially timed negative pulse corresponding to the fixed tube - is supplied to the output and energises a magnet 30 of e.g. a card-punching unit. Other means for supplying r.f. energy may be used, e.g. an oscillator for each digit position controlled by a ring circuit.
