Filed: 1953-08-25
Abstract: 745,014. Radar. MULLARD RADIO VALVE CO., Ltd. Aug. 25, 1953, No. 23426/53. Class 40 (7). An automatic range determining radar system stated to give a highly accurate value of range and also capable of determining the radial velocity and acceleration of a target includes two discriminator loops. Fig. 1 shows the system in block diagram form and in it 1 represents a stable oscillator whose output is fed to a pulse generator 2 to provide a series of pulses whose repetition frequency is divided by a factor of (say) 2,000 at 3 to give trigger pulses for the radar transmitter at TX. The output of oscillator 1 is also fed to adjustable phase shifter 6 whose output is used to control the generation of a phase shifted series of pulses at 7 and one of these pulses is selected each repetition frequency period in pulse selector 8 by the output of range determining circuit 4 and compared in time position with the object echo pulse from the receiver in double gate discriminator 9. The error voltage from the discriminator 9 is fed to operate motor 10 controlling the phase shifter 6 to maintain coincidence. The range determining circuit 4 comprises a sanatron circuit (see Specification 745,015) triggered by the output pulses from the divider 3 and producing an output pulse after a time determined by the control voltage fed to it from discriminator 5. The output pulse from circuit 4 is fed out at 0 to give a range indication, is supplied to pulse selector 8, and is also fed to the discriminator 5 where it is compared with the output from phase shifter 6 to produce the control voltage fed back to control the sanatron circuit timing. The circuit is manually adjusted to lock on to a selected radar echo signal and thereafter follows the echo automatically. The discriminator 5 need not be a sine wave discriminator but can be a double pulse discriminator similar to unit 9 fed from the output of unit 7. The sanatron range determining circuit, is very briefly described with reference to the circuit diagram of Fig. 3 (not shown), while the circuits of suitable sine -wave and pulse discriminators are described with reference to Figs. 4 and 5 (not shown).

Title: Improvements in devices for indicating the slackening of pneumatic tyres on vehicles
IPC: B60C23/06
Filed: 1922-08-31
Abstract: 189,420. Bosch Akt.-Ges., R. Nov. 23, 1921, [Convention date]. Puncture or deflation, indicating.-A signalling-device for indicating deflation of tyres while running comprises a lever h, which, when nearest the ground, may be laterally deflected so as automatically to ring a bell f which is mounted on a dust-proof cover g secured to the rim c. A toothed segment k secured to a spindle i, on which the lever h is pivoted, actuates a toothed wheel m mounted on a spindle t. A spiral spring ratchet-lock n surrounding the wheel m has one end free and the other end attached to the hub p of a cam-wheel o. A similar, but oppositely wound, spring q surrounds the hub p, one end being secured to the cover g. A spring hammer r mounted on the casing may be compressed by the cam-wheel o, so that on release therefrom it forces a striker s to ring the bell f. When the lever h is actuated, the rotation of the wheel m winds up the spring n so as to couple the wheels m, o together. The return motion of the wheel m, due to the action of the return spring u, uncouples the wheels m, o, the latter of which is held from return motion by the spring q. In this way even small movements of the lever h may become effective by addition.

Patent GB-983034-A (GB)
Title: Improvements in and relating to the electrical separation of dust
IPC: B03C3/013
Filed: 1963-06-14
Abstract: Dust particles in an electrostatic separator are coated by treating them with phosphoric acid to improve their electrical conductivity and thus enable the gas ions from the emission electrode to pass through the dust on the precipitation electrode p  and avoid a corona-effect on that electrode.  A component of phosphoric acid, at a higher temperature than that of the dust particles, can be added to the gas-stream in a wide range of concentrations and in different ways.  One way is to burn yellow phosphorus at the entrance to the separator to produce phosphorus pentoxide which condenses on the particles and in the gas-stream to form phosphoric acid or form droplets of pentoxide coated with phosphoric acid; the combustion of the phosphorus can be modified by varying the air supply and adding varying amounts of water vapour.  The phosphorus can also be burned purely with water vapour whereby phosphoric acid plus phosphine are formed.
