Patent GB-115662-A (GB)
IPC: G01N9/00
Abstract: 115,662. Pollard, A. F. C. May 7, 1917. Specific-gravity estimating-apparatus; thermometers.-In order to indicate or record the density or temperature of a flowing liquid, it is caused to flow through a movable system arranged about a fixed axis of rotation, the liquid, if required, being delivered into different vessels according as the density varies by predetermined amounts. In the form illustrated in Fig. 1, the movable system comprises a vessel 4 concentric with the axis of rotation A, a pipe 5, a vessel V1, and an outlet pipe 6, adjustable counterweights 10, 11, 12 being provided. The axis A may be supported by floats in tanks, and when measuring densities, temperature effects may be compensated by causing a standard liquid to flow through a pipe 52, a vessel V2, and an outlet pipe 62. In another form, in which the axis of rotation is slightly inclined to the vertical, the liquid vessels are formed by concentric pipes 4, 42, Fig. 3, carried by the axis, which is constrained in direction by brackets 26 at its ends, and supported by a float 8 in an annular tank 8<1>. In order to eliminate the effects of temperature changes, the liquid whose density is required passes through a vessel 31, in which is a coil 34 through which the standard liquid passes on its way to the supply tank 32. In order to use this form of apparatus for measuring the temperature of a flowing liquid, the liquid should he divided into two portions, one of which is brought to a standard temperature, the pipes 4, 42, being separated by an insulator of heat, the vessel 31 and coil 34 being dispensed with. In a further modification, the liquid-receiving vessel is mounted on an axis inclined to the vertical, and is provided with an adjustable counterweight 10 and an outiet 5, Fig. 9, shaped as shown. In other forms, as shown in Figs. 12 and 14, the outlet consists of a siphon 5 carried by a movable frame 41 or by knife edges A, and the liquid vessel 42 is divided into two compartments communicating at the bottom, and partly filled with a number of marbles if desired. According to Provisional Specification 6480/17, the apparatus may be used to collect those portions of a distilled spirit which exceed a predetermined density.

Title: Process for the treatment of gases from furnaces for the production of aluminium
IPC: C01B7/19
Filed: 1937-04-22
Abstract: In a process for the production of aluminium by electrolysis of alumina dissolved in a fluoride melt, the evolved gases are moistened with an aqueous solution of a substance which combines with the gaseous fluorine compounds to form a dust, and the dust is separated from the gases, as by electrical precipitation.  In carrying out the process an aqueous alkaline solution of soda or sodium hydroxide may be injected into the gases in an atomized state in such quantities that whereas the fluorine compounds are combined to form a dust, the sulphur dioxide content of the gases is substantially unaffected. The separated dust may be heated under oxidizing conditions to free it from water, tar, and carbon, and the residual gases be washed with an aqueous alkaline solution.  The latter may comprise a solution of slaked lime or of soda; in the latter case the resulting solution may be treated with calcined or slaked lime to precipitate calcium fluoride and/or sulphate and regenerate the washing solution.

Title: Apparatus for determining the direction of luminous radiation
IPC: G01S3/783
Filed: 1972-03-13
Abstract: 1380144 Encoding angular position SOC ANON D'ETUDES ET REALISATIONS NUCLEAIRES-SODERN 13 March 1972 [12 March 1971 21 Jan 1972] 11583/72 Heading G4H [Also in Division H4] Apparatus for determining the direction of a distant light source comprises at least one rectilinear slit producing a luminous line on a coding system formed by at least two tracks, perpendicular to the slit, of opaque and transparent segments covering photo-cells, the slit and coding system being supported by two parallel spaced sheets. As applied to a satellite altitude senser, the light from the sun passes through slit 15 delineated by a mask on quartz sheet 10. Varying directions of the sun correspond to different positions of luminous line L on coding system 25 and hence different binary words produced collectively by cells 23A to 23G. The coding system is formed by metal deposition on quartz sheet 20, masks being placed on the underside of the sheet so that the transparent portions of the coding system are profiled to compensate for variations in light intensity with angle of incidence #. The cell outputs are fed to comparator circuits (45A) to (45G) (Fig. 7, not shown) and give logic outputs at S. A reference cell 40 always illuminated by line L through transparent track 22R, provides a variable threshold so that spurious signals below this threshold do not cause outputs at S. For a large range of values of # two slits may be used (Fig. 5, not shown). The sheets may be held in an asembly (Fig. 6, not shown) having a compartment (37) for the electronic circuits. Additional cells (53A), (53B) (Fig. 8, not shown), may be provided to inhibit the outputs when the light source is in such a position that line L does not cut across all the tracks. For satellites with spin the additional cells may also furnish a signal to indicate that the sun is orthogonal to the apparatus (angle α=0, Fig. 1, not shown). In another embodiment (Fig. 11, not shown), for use in satellites with spin, a slit (50) and cell (53) indicate when the sun is orthogonal and produce a signal to enable the outputs to indicate the attitude angle # at only this instant. In a further embodiment (Fig. 15, not shown), cell (53) is illuminated by two slits (50A), (50B) at its ends and reference cell (40) is illuminated by slits (65A), (65B), at 45 degrees to the slit (15).

IPC: H04N9/64
Filed: 1973-03-09
Abstract: 1419694 Colour television SHARP KK 9 March 1973 [10 March 1972] 11610/73 Heading H4F Automatic hue control in a PAL receiver is effected by gating 1, Fig. 1, the swinging bursts from a received chroma signal and producing in APC circuit 2 a continuous subcarrier synchronous with the average phase of successive bursts i.e. at f s <SP>1</SP> in Fig. 3. This subearrier is passed via a phase control circuit 3 and a 90 degree phase shifter 4 to produce a second subcarrier f so  which is used to demodulate 20 along the fixed B-Y modulation axis. In addition this second subcarrier is fed to a polarity decision circuit 5 which senses the polarity of the chroma input signal and produces a positive or negative polarity D.C. decision signal in dependence upon whether the colour carriers f c1  and f c2  in the chroma signal are in the first and fourth quadrants of the phase diagram of Fig. 3 or in the second and third quadrants. In dependence upon this decision signal the phase of the subcarrier from circuit 3 is inverted in circuit 6 and its resulting phase is detected relative to the chroma signal in phase discriminator 7, integrated 8 and fed to phase control circuit 3 to control the phase of f s <SP>1</SP> to its correct phase of f s  and thus effect automatic hue control. To demodulate the swinging R-Y component a subcarrier is produced by gating 9 alternate bursts and detecting 10 their phase relative to f s  at the output of circuit 3, the resulting output being integrated 11 and used to control phase inverter 12 so that the appropriate sub-carrier f s <SP>1</SP> or f s2  is derived which is then line switched through 180 degrees in switch 13 in response to the output of a bi-stable circuit 16 controlled by line sync. pulses via delay 14 and shaper 15. In a second embodiment Fig. 2 the polarity decision circuit receives f s <SP>1</SP> and the chroma signal and its output determines whether the signal f s0  is inverted in circuit 6. The phase of the output from circuit 6 is detected relative to the received chroma signal and the resulting sequential outputs subtracted and integrated 8 and fed to phase control circuit 3.

Abstract: 559,752. Aircraft control surfaces. WESTLAND AIRCRAFT, Ltd., and PETTER, W. E. W. Aug. 27, 1942, No. 12090. [Class 4] In order to vary the hinge moment of an aircraft control surface, means are provided for altering its thickness. particularly at that part of it to the rear of the hinge, either as a final adjustment while on the ground, or by the pilot during flight or as a consequence of the control surface being moved from its mean position. Fig. 1. shows an elevator pivoted at e and having a main spar supporting tubular ribs c connected together at their trailing edges. The ribs can be bent outwards as shown by a right and left hand screw-bolt h having a pinion i actuated by a light rack j or by insertion through the elevator of an adjusting rod. Alternatively a light cable may actuate several of such screws. In another form the ribs are adjusted by. toggle links actuated by a rod and turnbuckle, and the links themselves may be adjustable in length to give a different range of adjustment to the upper and lower surfaces. Fig 4 shows an aileron in which the ribs are connected by links r, t to two-armed levers p mounted on a shaft o extending through the aileron. The outer end of this shaft is pinned to a lever u extending to a point forward of the hinge e where it is guided in a slot. Upward deflection of the aileron causes the ribs to bulge,outwardly and downward deflection causes them to be pulled inwardly. An opposite effect is produced either by reversing the.position of the links r, t or by guiding the forward end of the lever u in a slot to the rear of the hinge e. The two arms of the lever p may be of different lengths. Either the upper or the lower link may be omitted in which case one surface remains unaltered. Fig. 5 shows another form in which the ribs have slotted plates v engaged by pins u on a guided tube x, the forward end of the tube having a roller 2 engaging a cam z shaped to give the desired variation of contour to the surface as it is deflected. The device may be used in conjunction with a horn balance and a tab control. Specification 448,249 is referred to as an example of a wing having variable camber, and Specification 346,251 as an example of a wing with flexible rear portion to change the camber automatically.
