Title: Improvements in pneumatic tyres
Inventor: TREVASKIS HENRY WILLIAM
IPC: B60C9/00
Filed: 1954-11-06
Abstract: 786,164. Pneumatic tyres. DUNLOP RUBBER CO., Ltd. Oct. 19, 1955 [Nov. 6, 1954], No. 32174/54. Class 144 (2). A pneumatic tyre having a rubber or like body is reinforced by a cord winding arranged in at least one double layer with the cords of one layer crossing those of the other layer to form a lattice, and the cord in each layer extending in a series of turns progressing continuously around the tyre in the same direction, each turn consisting of two U-shaped loops 4, 7 each passing tangentially from one edge of the tyre, through the sidewalls and crown and tangentially into the other axially-aligned edge, and two intermediate axially-aligned arcuate portions 5, 6 and 8, 9 disposed one around each edge of the tyre and each of sufficient length to cause the edges of the tyre to contract in diameter to grip a wheel rim when the cord is tensioned by inflation of the tyre. The arcuate portions of each turn may subtend an angle with the tyre centre of between 40 and 300 degrees, and each U-shaped loop may be either symmetrical or asymmetrical about the medium plane of the tyre. The cord is firmly embedded in the rubber of the tyre to prevent slippage and may comprise rubber-coated twisted strands of twisted filaments of steel or natural or synthetic textile material. Specification 786,162 is referred to.

Title: Improvements in or relating to digital-analog servo circuit
IPC: G05B19/39
Filed: 1956-10-23
Abstract: 839,126. Programmed electric control systems. NORTH AMERICAN AVIATION Inc. Oct. 23, 1956 [Dec. 23, 1955], No. 32241/56. Class 40 (1). In a servomotor. circuit wherein control is effected by a digital error signal resulting from a comparison of a programmed digital input signal and a corresponding signal derived from a magnetic tape or other record driven by the motor, the digital error signal is first converted into analogue form and then combined with a fine control analogue signal derived from the tape pick-off. As shown, the servomotor M, Fig. 1, drives. through a fluid pressure system 89-41, a magnetic tape 3 on which is recorded a sine wave. Pick-off 1, 2 are disposed an odd number of quarter-wavelengths apart. Their outputs, after amplification and demodulation at 5, 6, are fed to respective flip-flops 7, 8 the outputs of which are combined in. a direction circuit 9 to produce a " distance " pulse over line 10 for each quarter wavelength traversed by the tape relative to the pick-offs, and associated " direction " pulses over line 11 corresponding to the direction of the relative movement of the tape. These pulses are compared in a reversible error counter 12 with the programmed distance and direction input pulses from a director 82. The resultant digital error (difference) signal is converted into analogue form at 13 (e.g. by summing resistors 14-17 in the case of a binary counter) and fed via an amplifier 39 to drive the motor M in the corrective sense. For fine control, Figs. 1, 7, push-pull sinusoidal outputs Œ A, Œ B taken from the demodulators 5, 6 are added algebraically in selected combinations. This is effected by gating the outputs Œ A, Œ B by diodes 66-69 according to the outputs of the flip flops 7, 8, to mechanize four logical equations as disclosed in the Specification, whereby the required analogue fine control voltage is fed over resistor 27 and added to the coarse error analogue step signal to provide a continuously varying control signal.

Abstract: 1,008,156. Rocket propulsion. BRISTOL SIDDELEY ENGINES Ltd. Aug. 12, 1964 [Aug. 16, 1963], No. 32477/63. Heading F1J. [Also in Division B7] A rocket engine has co-axial fuel and oxidant pumps about the common axis of which it is pivotably mounted in an aircraft fuselage (see Division B7). The engine has a fuel pump 8 (Fig. 6) and a hydrogen peroxide (oxidant) pump 7 driven by a turbine 9 powered by steam obtained by decomposing hydrogen peroxide from the outlet 35 of the pump 7 or from a starting tank 39. Compressed nitrogen from line 44 pressures the oxidant tanks 31, 39 and opens a valve 47 to allow oxidant to flow to the pump 7 when a valve 45 is opened. This is done by mounting the valve and, bellerank 51 on the fuselage and rocking the crank by a pin 52 on the engine frame as the engine is pivoted to the operative position. The engine is pivoted by a compressed nitrogen operated ram 20, and the combustion chamber may be purged by nitrogen from a line 58. Specifications 1,008,157 and 1,008,158 are referred to.

Title: Manufacture of oxy-sulphonic acids of hydrocarbons of high molecular weight
IPC: C07C309/43
Filed: 1936-11-27
Abstract: Hydroxy-sulphonic acids of pyrene, chrysene and fluoranthene are made by treating a hydroxy-compound of pyrene, chrysene or fluoranthene with a sulphonating agent, preferably in presence of an organic solvent or suspension medium; hydroxy-sulphonic acids of chrysene may be made by heating an aminochrysene sulphonic acid in an acid medium, such as dilute sulphuric or hydrochloric acids.  Sulphonating agents specified are sulphuric acid, chloro-sulphonic acid, and pyridine sulphotrioxide, which may be used in solvents or suspension media such as nitrobenzene, chloroform or trichlorbenzene.  In examples: (1) 3-hydroxypyrene is sulphonated to a 3-hydroxypyrene mono-sulphonic acid (which may be converted by means of caustic alkali to a dihydroxypyrene and the latter oxidized to pyrene quinone with potassium ferricyanide), or a 3-hydroxypyrene disulphonic acid; (2) a 2-hydroxychrysene monosulphonic acid (which may be methylated to a 2-methoxychrysene sulphonic acid or fused with alkali to give a di-hydroxychrysene, which may be di-acetylated) and a disulphonic acid are obtained similarly; (3) 4-hydroxyfluoranthene is sulphonated to give a mono- and a di-sulphonic acid and (4) 11-hydroxyfluoranthene is monosulphonated; (5) sodium 2-aminochrysene monosulphonate (obtained by monosulphonating 2-aminochrysene) is heated with 1 per cent hydrochloric acid to give a 2-hydroxychrysene monosulphonic acid.  The hydroxychrysene sulphonic acids couple with diazo compounds.

By turning this cap the separation of the lenses 15, 16 can be varied in order to focus objects at different distances. With the telescope system arranged as shown objects at abnormally large distances can be photographed ; for focusing very near objects the telescope system is reversed so that the lens 15 is between the lens 16 and the filter.
