Title: Apparatus for measuring the density of flowing fluids
IPC: G01N9/18
Filed: 1935-09-21
Abstract: 446,069. Mechanical relay and followup devices. SCHOLZ, W., Wartha-Frankenberg, near Breslau, and ECKARDT. AKT.- GES., J. C., 72, Pragstrasse, Cannstatt, Stuttgart, both in Germany. Sept. 21, 1935, No. 26236. [Class 118 (ii)] [See also Groups XX and XIX] A float, particularly for measuring the density of flowing liquids, is immersed in a container having an overflow which is shaped so that a meniscus for centring the float is formed and the position of the float is automatically indicated or recorded. In the form shown, the liquid to be tested passes from pipe 1 through a branch-pipe 2 to a U-shaped pipe 3 having an enlarged portion 3<1> to receive the float 4 and a chamber 5 providing an adjustable overflow 6. At its top the enlarged portion 31 has a sharp-edged inwardly tapering nozzle 7 made of liquid repelling material such as soapstone or steatite so that the liquid overflowing at 7 forms a meniscus tending to centre the spindle 9 of the float 4. A member 26 prevents the flow of liquid from jarring the float 4. Time - controlled cams 14, 24, 16 control respectively a lever 11 adapted when rocked to allow clamping arms 10 to grip the spindle 9, a similar lever 23 operating clamping arms 22 for securing a train of links 19, 30 terminating in a recording pen 20, and a feeler 15 adapted to adjust the position of the link 19 and pen 20 by rocking about its pivot 17 until stopped by the top 18 of the spindle 9. The arrangement is such that the spindle 9 is clamped and the links 19, 30 freed whilst the feeler 15 is operative and the spindle 9 freed and links 19, 30 clamped whilst the feeler 15 is inoperative. If desired, the record on the chart 21 may be intermittent. The recording mechanism may be provided with contacts adapted to give signals at predetermined densities or operate relays controlling the density of the liquid. Alternatively, the record may be made by a disc 18 on the top of the spindle 9 either by a spark discharge or a peripheral inking pad intermittently pressed laterally against the record sheet, e.g. by an electromagnet.

Abstract: 880,889. Electrical measurement of shaft thrust. METZMEIER, E. July 30, 1959, No. 26237/59. Class 40 (1). In a device for measuring the thrust of the shaft 2 of a ship or aircraft propeller, annular springs 6 and 6<SP>1</SP>, carrying strain-sensitive devices such as resistance wires are respectively expanded and compressed under the action of tapered ring 5, due to the thrust of the shaft transmitted via collar 3 and thrust blocks 4. Temperature compensation may be provided by further resistance windings on a ring of similar material to that of the springs 6 and 6<SP>1</SP> mounted, so as not to be subjected to thrust forces, in a space in between the annular springs (Figs. 6 and 7, not shown). Errors due to friction between the springs and the tapered ring may be reduced by inducing high-frequency vibrations of either the ring or springs by magnetostrictive transducers (Figs. 8 and 9, not shown).

Title: Improvements in and relating to servo-mechanisms, and control means therefor
IPC: G05D3/14
Filed: 1947-09-29
Abstract: 643,036. Automatic speed control systems. BRIGGS, G., and BRITISH VACUUM CLEANER & ENGINEERING CO., Ltd. Sept. 29, 1947, No. 26258. [Class 38 (iv)] [Also in Group XXXVII] Relates to servo-mechanism in which the controlled and control elements operate from a single A.C. source, or from A.C. sources of the same frequency. As shown, the controlled element is an A.C. commutator motor which has its armature 31 supplied through a transformer 32, its field winding 29 being connected to the secondary winding 28 of a transformer 24 having opposing primary windings 23, 25. The winding 25 has a greater number of turns than the winding 23 and is supplied from a source 22, being connected in series with a phase-advancing condenser 26 and in parallel with condenser 27. The winding 23 is connected in the anode circuit of a gas-filled gridcontrolled valve 19 the grid circuit of which comprises a potentiometer 13 and a centretapped secondary winding 11 of a mainssupplied transformer, a bridge circuit being completed by the A.C. windings 14, 15 of two saturable chokes. The phase and magnitude of the voltage, which is effective to control motor direction and speed, induced in winding 28 from winding 25, is dependent upon the firing-period of the valve 19, variation of which causes a corresponding change in the saturation of the transformer-core and consequent variation of the inductance of the winding 25. The connection of windings 23, 25 in anti-phase has the effect of distorting the voltage developed in the former and prolongs the firing-period of the valve. When the thyratron is cut off a voltage impulse from the winding 23 is communicated to the winding 25, a voltage of substantially sinusoidal form being produced in the latter. The valve is controlled by varying the direct-current supplied to saturating winding 14a, such variation being in accordance with the magnitude and direction of the displacement between the controlling and controlled elements of the system. A saturating winding 15a is supplied with a feed-back voltage dependent upon the position of the controlled element, the phase-shift of the grid voltage produced by such signal being in the inverse sense to that afforded by the signal applied to the winding 14a. The voltage applied to winding 15a acts as a balancing signal which stops the motor 30 when it is driven to the desired position. When the motor is near its position harmonic currents produced in windings 25, 23 become effective to afford an alternating torque for the motor, so overcoming static friction. In a modification the armature of the motor is connected to the secondary winding 28 of the transformer, the field winding being connected to the source. The motor may be of the two-phase induction type. Specification 663,030 is referred to.

Abstract: 1479041 Ion-exchange apparatus FLUID POWER RESEARCH INC 14 June 1974 [15 June 1973] 26552/74 Heading B1J A fluid treating apparatus has an inlet means for connecting said apparatus to a supply of fluid under pressure to be treated, a chamber defining two treating sections each containing a bed of surface-active treating material particles, fluid inlet and outlet passages connecting with said chamber, said chamber being constructed and arranged to permit flow of fluid througl said beds of treating material in series and each treating section having containment means to prevent the escape of said treating material particles therefrom, the particles in a first of said treating sections being packed between said containment means of the first treating section so as to occupy substantially the entire volume therebetween and the particles in a second of said treating sections being contained therein in a quantity the volume of which is substantially less than the total volume of said second treating section, a volume for storing a charge of a regenerating fluid for said particles, an inlet to the volume being for communicating the pressure of the fluid under pressure to the volume, and an outlet from the volume, the outlet communicating the said volume to the said chamber to feed the charge to the particles during a regeneration mode, meter means responsive to the volume of fluid to be treated supplied to said beds of particles in said chamber, and switching means for directing the fluid to be treated in an operational mode to flow in a first direction through said beds in the said treating sections, first through the bed in the first section and then through the bed in the second section and in the regeneration mode to apply its pressure to said volume to displace the charge of regenerating fluid through the outlet from the volume and thence through the beds in series in the opposite direction, said switching means being responsive to said meter means, whereby said apparatus will be switched from the operational mode to the regenerating mode after treatment of a predetermined volume of the fluid to be treated. As shown, water to be softened passes upwards through tightly-packed bed 80 then through looser particles in bed 78. When the metering assembly 34 indicates that a predetermined amount of water has passed, water is allowed to flow via line 160 to open valves 52 and 54, allowing the incoming water to flow via line 224 to the brine tank 40, driving brine via line 44, valve 56 and passage 74 through the beds in the downward direction. Loose bed 78 is thus fluidised during softening but packed during regeneration. Means may be provided to prevent the automatic change-over to regeneration when softened water is actually being drawn from the apparatus.

Abstract: 398,646. Uniting by fusion ; welding. BRITISH THOMSON-HOUSTON CO., Ltd., Crown House, Aldwych, London.-(Assignees of Chapman, V. J. ; 25, Lakewood Avenue, Schenectady, New York, U.S.A.) Sept. 29, 1932, No. 27067. Convention date, Oct. 1, 1931. [Class 83 (iv).] Arc-welding apparatus is provided with means for withdrawing stick electrodes 10 from a magazine 5 and automatically butt-welding them in succession to the working electrode 14. The machine shown comprises a welding head 1 mounted on a carriage 2 for traverse along a track 3 by a motor 4. The electrodes are fed from the magazine to the work 9 by rolls 6, 7 driven at the same speed by belting 13. The rolls 7 are in constant driving engagement with the stick 14 and the larger rolls 6, which normally slip on the stick 15, are made to grip the stick at intervals by energizing a solenoid coil 32 that operates toggle-mechanism 18 to bring the roll shafts 19, 20 nearer together. By this means, the stick 15 is forced against the stick 14 during the butt-welding of the sticks effected by current supplied through a circuit including switches 39, 25 and leads 26, 27. This circuit is made by a gravity switch lever 28 which automatically closes when a stick leaves the magazine and makes a circuit through coil 30 to close switch 25 and open a circuit through coil 36. This allows a switch 33 to close a circuit through the coil 32, after an interval determined by a dashpot 38, for causing the rolls 6 to grip the electrode 15. The switch lever 28 is automatically operated by the pressure of a fresh stick from the magazine to break the circuit through the coil 30 and thereby cause the release of the rolls 6 and the stoppage of the butt-welding current.

Abstract: 982,767. Self-propelled missiles. DORNIER SYSTEM G.m.b.H. July 16, 1962 [July 20, 1961], No.27211/62. Heading F3A. [Also in Division B7] A guided self-propelled missile having a body 1 has a starting rocket motor 2 from which the gases are first directed forwardly, then ejected rearwardly through an annular nozzle 4, the gas exit being in front of the centre of gravity and the centre of pressure of the missile. In addition a second rocket motor 5 with annular nozzle 7 is arranged at the rear of the missile symmetrically with the motor 2, so that the emergent gases are directed oppositely to those of motor 2. Tail fins 8 are mounted on a ring 9 which bears against a stop 10. Devices may be arranged near the outlet nozzles to deflect the gas flow and so control the steering, e.g. flaps 23, Fig. 8. The steering may be remotely controlled or controlled by instruments within the missile in a space 1<SP>11</SP>. Motor 2, which may be cut out when a particular speed or location has been reached, may be detached from the missile, the missile then continuing in its predetermined path with its end surface 15 exposed so that observation instruments in a space 1<SP>1</SP> come into operation. When the missile nears its goal, the motor 5 is put into operation and the issuing gases first brake the forward motion then reverse the direction of travel. The tail unit 8, which is displaceable, slides along guides 11 to the other end of the missile, where the ring 9 bears against a stop 12. As on the forward travel the motor may cut out and become detached and a braking device such as a parachute 14 may be used to check the landing speed of the missile. If the motor 5 has not been discarded the gases may be used to brake the motion, e.g. by blowing off the deflecting devices in the head 6. Gyroscopic stabilizers may be provided in the head 6, alternatively a pendulum 19, Fig. 6, may act on levers 20 to operate deflectors 21. The missile may also be stabilized by using deflectors which cause the missile to rotate, the ring then being freely mounted, so that the tail unit does not rotate or only to a limited extent.
