Patent GB-768892-A (GB)
Title: Process for the production of terephthalic dialdehyde
Filed: 1955-04-06
Abstract: Terephthalic dialdehyde is produced by a process wherein a derivative of p-xylene which is disubstituted by halogen atoms in the o ,o 1-position is oxidized in the gaseous phase and in the presence of an oxidation catalyst by means of air at a temperature of 300-600 DEG C.  Catalysts mentioned include molybdenum oxide, uranyl molybdate and vanadium pentoxide or pumice.  In examples: Terephthalic dialdehyde is obtained when p-xylylene dichloride vapour is passed with air over a vanadium pentoxide-pumice catalyst.  Terephthalic acid is removed from the product by continuous extraction with benzene and the desired product is obtained by evaporating the benzene from the solution and steam distilling (1); p-xylylene dibromide is employed as starting material in a similar process (2). p-Formyl-benzoic acid is also produced as a by-product.

Title: Improvements in variable pitch airscrews, marine propellers and fans
IPC: B64C11/30
Filed: 1943-06-28
Abstract: 565,912. Automatic control systems for variable pitch propellers &c. ANDERSON, J. R. June 28, 1943, No. 10463. [Class 38 (iv)] [Also in Group XXXIII] Fluid pressure.-The pitch of a marine or an aerial screw propeller or fan is controlled by means including a pressure-sensitive device exposed to the pressure at a selected part of the blade ; the control may be effected by electric or hydraulic means. A duct leads from the aperture 16 to a chamber 20, e.g. in the blade root or the hub, containing a diaphragm such as an aneroid capsule, the other side of which is subject to constant pressure or to the pressure at another blade point, the pressure at the two points varying oppositely with the angle of attack. The diaphragm actuates a switch arm 22, Fig. 7, to energize one of the alternative solenoids 38, 40, and so actuate a switch 32 to drive a pitch-changing motor 30 in one or other direction. Any one of the three switches 28, selected by a manual switch 54 in accordance with altitude of an aircraft, is used to control all the blades. The current is derived from a battery 42 and led through a manual switch to connect either with the switch 54 and switches 28, or with contacts 64, 66 by which the solenoids are directly energized for arbitrary change of pitch, or with a contact 68 and switches 70, subject to pressure on the opposite sides of the blades, and operating to cause the motors to reverse the pitch for diving or braking. The blade aperture may be situated at a point where pressure varies most with speed at the same angle of attack. Separate pitch-changing motors in parallel, geared together, may be provided for the blades. A centrifugal governor may prevent overspeeding. The system may be applied to the blades of counter-rotating propellers which need not be mechanically connected.

Title: Method and apparatus for measuring mass flow and density
IPC: G01N9/00
Filed: 1964-03-12
Abstract: 1,062,072. Measuring electrically; measuring fluid flow. V.J. CUSHING. March 12, 1964 [March 12, 1963], No. 10603/64. Heading G1N and G1R. Fluid flow or density is measured by imposing known variations on the flow of the fluid in a section of a conduit, and measuring the consequent pressure variations. The flow variations may be produced by axially vibrating the throat 86, Fig. 3, of a Venturi, through which the fluid is flowing, or the funnel portions 87, 88, or all of them, by means of a motor M with an eccentrically mounted member 107 which slides in a slot 106. A diaphragm type or variable capacitance pressure gauge 115 measures the pressure at the throat of the Venturi; or it may measure the differential pressure in the Venturi 55, 60 Fig. 1 (not shown). The pressure signal is filtered in a phase sensitive detector 118 which is also supplied with a signal derived from the Venturi vibrating mechanism by means of a magnet 110 and a coil 111. The first harmonic of the pressure signal indicates the fluid flow velocity, and from the second harmonic the density can be derived. Alternatively, the flow variations may be induced by a piston axially oscillating in a cylinder arranged parallel with and outside the conduit and open to the fluid via a port on each side of the piston Fig. 4 (not shown), and the pressure sensing device may be a Piezoelectric ring surrounding the Venturi throat Fig. 5 (not shown). A plurality of devices, each comprising a Venturi and one or two pressure transducers, may be arranged in series or parallel.

Title: Tyre under-inflation warning device

Abstract: 1447244 Pneumatic tyre under-inflation indicating device DUNLOP Ltd 10 May 1974 [17 May 1973 9 March 1974] 23482/73 and 10656/74 Heading B7C A pneumatic tyre under-inflation warning device, adapted for mounting on a wheel rim and within the inflation chamber, comprises a striker movable between a first position in which it is out of contact with a striking surface on the wheel rim and a second position in which it contacts the striking surface, the striker, when in the first position, in use, with the inflation pressure below a predetermined value, being engaged by the deflected tyre in the foot print region as the tyre rotates and moved into the second position to emit a signal indicative of the inflation pressure being below said value. The device of Fig. 1 includes striker 1 and a housing 2 which is mountable on the wheel rim 4 together with lubricant containers by means of a band 5. In a first modification, the striker may be telescopic with the two elements (16, 17) (Fig. 8, not shown) held extended by a spring (19) and in a second modification, the striker 1 is urged towards the rim by a spring (12) (Fig. 3, not shown). In the latter modification, even if the tyre pressure is below the predetermined value, the member will be retained in engagement with the rim as long as the vehicle does not exceed a "safe" speed. In the device of Fig. 2 the striker 1 includes a striker head 20, a cap 11 and a spring 7. When cap 11 is depressed by the tyre to cam pawls 8 outwardly, the striker head is biased by spring 7 into engagement with the rim. After one actuation, the head 20 is returned to the illustrated condition by centrifugal force readily for the next depression of the cap. The device of Fig. 4 includes a striker 51 in the form of a pivoted lever. In a modified device (Fig. 5, not shown) a spring (57) biases striker head 54 into contact with the wheel rim, thus the device will not produce a signal unless the vehicle exceeds a "safe" speed, when the tyre is under-inflated. Pivot 52 (Fig. 4) may be replaced by a rubber bush, and the rubber bush in the modified device may be such as to obviate the need for the spring (57). The device may include a striker mounted on a block of elastomer (Figs. 6, not shown, and 7).
