Title: Improvements in and relating to flushing tanks, cisterns or like
IPC: E03D1/08
Filed: 1931-12-31
Abstract: 392,647. Siphon-discharge waterwaste-preventers. HOWSON & SONS, Ltd., G. and HOWSON, R..G., Eastwood Sanitary Works, Hanley, Stoke-on-Trent. Dec. 31, 1931, No. 36121. [Class 26.] In siphon fittings of the piston and cylinder siphoning type for flushing cisterns or the like, the pull on the piston is imparted in a line adjacent the shorter limb of the siphon fitting by the use of a rotatable element carried in a bracket from the head of the siphon without other means of direct connection to the cistern. In the form shown in Fig. 1, in which the entry of water into the tank a is controlled at the inlet c by means of the usual ball tap b actuated by a float d carried at the end of a curved arm d<1>, the siphon fitting g comprises an inverted U-tube having a longer limb g<1> fitted in the bottom of the tank, an upper part g<2> which forms part of the shorter limb g3 and is secured by welding or otherwise to the part g<1>, and a tapering branch h<1> connecting the part g<2> with the cylinder h, of which it forms the lid. A double armed bracket i secured to the part g<2> carries an integral boss i<1> guiding an operating-rod j, which is adapted to slide in a position adjacent a flanged wheel k mounted on the bracket i, causing a chain or other flexible element l passing round the wheel k and connected at one end to the top of the piston rod h<2> to raise the piston n when the rod j, the lower end of which is connected with the other end of the chain l, is depressed. The piston n is formed with a number of holes concentrically provided about the centre thereof, and is covered with a sheet n<1> of metal, vulcanite, or the like. The rod passes at the top through a metal bush a<2> in a plate a<1> covering the tank. In the form shown in Fig. 3, a toothed pinion k<1> engaging a rack h<1> on the upper end of the piston rod and a rack formed on the operating rod j is employed instead of the flanged wheel k. The form shown in Fig. 4 is adapted to flushing cisterns of the high level type, and comprises an operating chain or flexible element l passing over two flanged wheels k<2>, k<3> mounted on double armed brackets i2, i<3> connected together adjustably by a rod o screw-threaded at the ends, the bracket i<3> being provided with a screw-threaded hole for the reception of a pin p adapted to bear on a rubber pad p<1> which is set on the upper edge of the tank a.

A gas turbine plant comprises a compressor, an annular combustion chamber and a turbine all arranged coaxially, air supplied by the compressor passing into the casing which is disposed around the combustion chamber with a velocity component in the peripheral direction, the air stream being then divided into a combustion air stream and a dilution air stream which is used for reducing the temperature of the combustion gases to a value acceptable by the turbine blades. The combustion chamber wall is provided with openings through which the combustion air flows, the air entering the combustion chamber with substantially no component of velocity in the peripheral direction, and with further openings which impart no guiding action on the dilution air streams flowing therethrough. The embodiment shown comprises a radial flow compressor 1 and an inward radial flow turbine 4 mounted on a common shaft 2, an annular combustion chamber 30 being disposed between the compressor and the turbine, the whole assembly being disposed within an outer casing 5. Air enters the compressor through inlet 6 and is discharged therefrom with a peripheral component of velocity through the diffuser vanes 7. One portion of air is directed radially inwardly through inlet openings 12 in the combustion chamber end wall 10 into the combustion zone with no peripheral component of velocity. A second portion of air flows through the turbine inlet nozzle guide vane assembly 16 into the space 31 and from there radially inwardly through inlet openings 12 in the combustion chamber end wall 18 into the combustion zone with no peripheral component of velocity. Fuel is supplied through the bore 23 in the shaft 2 and discharges radially outwardly into the combustion chamber through radial bores 24, the resulting combustion gases discharging through the annular outlet 21 and being directed by the guide vane assembly 16 on to the blades of the turbine rotor 4. A further portion of air constituting dilution air passes through plain holes 28 in the outer wall of the combustion chamber into the combustion gases to cool them, this air entering the combustion chamber with its component of peripheral velocity since the holes 28 impart no guiding action on the air flowing therethrough. A spark ignition device 29 is provided.

Light from the source 2 3  is collimated and by a lens 9 and focused by the lens system 3 under test on a plane P<SP>1</SP> . The image produced is focused by the microscope objective 8 on the sinusoidal unit constant transmission template 22 whence light passes to the photo-multiplier 6. The template comprises a drum carrying a pattern of sinusoidally varying width or transparency. A number of sections with different spacial frequencies may be provided so that the modulation transfer factor may be measured at a plurality of frequencies in sequence. The slit 18 and the template 22 may be rotated about the optical axis to make measurements in the tangential and sagittal planes. The elements in the dotted box may be rotated about an axis perpendicular to the optical axis to make off axis measurements, Fig. 2 (not shown). Autocollimators 20, 25 are provided to check the setting of the collimator 9 and the centring of the image on the template respectively.

Abstract: 1,192,560. Crystal oscillator circuits. WESTERN ELECTRIC CO. Inc. 10 Aug., 1967 [17 Aug., 1966], No. 36781/67. Heading H3T. In an oscillator having a crystal tuning means CR comprising a crystal body CW coupling two resonators, one resonator PR is connected in the feedback path of an amplifier, e.g. transistor TR, the other resonator SR is adapted to supply output signals to a load network LN and the coupling is such that depending on whether the other resonator SR is terminated by a low or high impedance the resonators pass energy over substantially only a first or a second pass-band respectively. The trimmers CT 1  and CT 2  tune the primary and secondary resonators PR and SR to the same operating frequency. The coupling between the resonators PR and SR may be critical or less than critical and is varied by adjusting the mass loading of the electrodes E1-E4 or the spacing between electrodes. Frequency drifts of the oscillator tuning relative to the filter tuning due to temperature changes are avoided by forming the resonators PR and SR on the same crystal body.

[Also in Groups XXXIII] An aircraft control system comprises means responsive to movement of a pilot's control member to produce a first signal, means comprising a gyroscope and a rate gyroscope for producing two further signals each of which is a function of movement of the aircraft about an axis of reference, a motor driving a controlled member, e.g. a control surface or a jet deflection device and energized by an amplifier having all three signals as inputs, means responsive to the position of the controlled member to derive a signal applied to the amplifier, and means responsive to the rate of displacement of the controlled member to derive a signal applied to the amplifier through a delay network. In the embodiment described, the controlled member is a rudder 9. The manual control, gyroscope, and rate gyroscope are arranged to control the balance of three Wheatstone bridges 4, 5 or 6 energizing three input coils 1, 2, 3 of a polarity sensitive relay device, which has two further input coils 13, 14. A contact maker 7 makes one or other of contacts 8 according to the sign of the algebraic sum of all the inputs, and energizes a reversible motor 16 to drive the surface 9 in one or other direction. The position of surface 9 controls the balance of a Wheatstone bridge 12 energizing coil 13, and a tachometer generator 11 is driven by surface 9, the resultant rate of movement signal being fed through a delay network 15 to coil 14. The motor has an electromagnetic brake (not shown), the effect of which is proportional to the motor input voltage. The contact maker 7 oscillates between the two contacts 8, energizing motor 16 fully in opposite directions alternately. The feed-back signals at coils 13 and 14 ensure that when there is a resultant input on coils 1, 2 and 3 the oscillation of the contact maker is appropriately asymmetrical, to apply a mean potential to motor 16 such that the control surface 9 is driven towards a steady state position corresponding to the algebraic sum of the inputs on coils 1, 2 and 3. The relay device may be replaced by an electronic or magnetic amplifier.
