Patent GB-611724-A (GB)
Title: Pulsed radio-location system
IPC: G01S13/58
Filed: 1945-08-29
Abstract: 611,724. Radiolocation. PATELHOLD PATENTVERWERTUNGS- & ELEKTRO-HOLDING AKT.-GES. Aug. 29, 1945, No. 22299. Convention date, July 26, 1944. [Class 40 (vii)] In a pulse-transmission system for observing moving objects, the pulses received after reflection are combined with transmitter' energy to produce impulses modulated in amplitude at the Doppler frequency. When the transmitted pulses are longer than the maximum reflection period so that the transmitted and reflected pulses overlap in time, the Doppler frequency can be directly obtained by combining the overlapping portions. When the transmitted pulses are relatively short, energy from the transmitter oscillator is combined with the reflected pulses producing an impulse train, the envelope of which gives the Doppler frequency. In the system shown, a multivibrator J keys a push -pull amplifier T which is fed from a continuous-wave oscillator O and the pulse output is radiated. Reflected energy is received in a receiver-detector M, the preliminary stage of which also receives some of the continuous energy from the oscillator O. The beat frequency output is fed through a limiter A comprising biassed rectifiers D1, D2, and a filter B, preferably of the band-pass type, to a frequency measuring device K. The device K comprises a pair of valves V6, V7 whose cathodes are connected through a condenser C8 charged by a battery Q2, the arrangement being such that the discharging and charging of the condenser C8 is controlled by the beat-frequency input. The output of the valve V6 is fed to an instrument Z, the output being the discharging current of the condenser. C8 and its mean value being proportional to the input. The device K may also contain a relay or indicator which operates as soon as a beat frequency occurs. In a modification, Fig. 7 (not shown), the limiter A is replaced by a gating circuit controlled from the multivibrator J through a variable delay line, the delay of which is periodically varied. The time-base of a cathode-ray tube may be triggered at the beginning of each variation period so that the position of a deflection corresponding to an echo signal gives the distance of the reflecting object. A super-regenerative receiver may be employed in which the frequency of the quench voltage coincides with the pulse-recurrence frequency and the phase of the quench voltage is adjustable and may be periodically varied.

[Class 38 (i)] In a thermionic valve of the type having circularly disposed contact pins 3 and a central spigot 4, there is provided a locating pin 5 outside the contact pin circle, or as shown consisting of sheet metal bent to a T-shape, the extremities of the cross-arm thereof being secured, e.g. by welding to two adjacent contact pins. Fig. 3 shows a holder for the valve comprising insulating sheets 11, 21 riveted together, two of the socket holes 13 therein being joined together to form an aperture 15 which is shaped to receive the locating pin 5. Located across the upright of the T of aperture 15 is a U-shaped spring wire 9 which engages a notch 8 in the upright 7 of the locating pin when the valve is inserted in the holder. A screen on the valve may be earthed by a metal strip fixed at one end to the locating pin, the other end extending up the outside of the screen on to which it is pressed when the valve is inserted in the holder. The screening of the valve may be completed by providing a metal sheet or coating on one of the insulating sheets of the holder and connected to the valve screen preferably through the locating pin. Alternatively, the latter may be used as a contact pin, contact being made thereto through the spring catch.

Title: Method for producing alkali metal and/or alkali-earth metal phosphates
IPC: C01B25/30
Filed: 1964-05-29
Abstract: In the manufacture of alkali metal and/or alkaline earth metal phosphates by introducing an alkali metal and/or alkaline earth metal compound into P2O5-containing gases obtained by burning phosphorus, e.g. as described in Specifications 1,035,971 and 1,035,972, there is employed a 1 to 50 mol per cent excess of P2O5 over that required for a final product having a desired metal oxide to P2O5 molar ratio. The more acid the desired product, i.e. the lower the metal oxide: P2O5 ratio thereof, the greater is the required excess.  For products of the same composition, the higher the reaction temperature the greater is the required excess.  For example an excess of about 40 mol per cent is required to form products having a metal oxide: P2O5 ratio of 1.0, and about 2% for a ratio of 1.5.  Preferred temperature ranges and corresponding required excesses of P2O5 for products having a desired range of compositions are tabulated.  Higher temperatures are required the more alkaline the desired product. Other things being equal potassium compounds require higher temperatures than sodium compounds.

Abstract: 859,006. Moulding polythene &c. NORTON, H., NORTON, H. V., NORTON, L. B., and NORTON, D. E. April 15, 1959 [Jan. 16, 1958], No. 22440/57. Class 87(2). A method of moulding a material which tends to entrap air when moulded or which is oxidised when heated in air to a temperature at which it flows comprises placing the material in a mould in a vacuum-tight vessel, evacuating air from the vessel, and heating the material so that it flows and assumes the mould contours. Granular polythene is spread on a wire helix 22 in a mould frame 21 which is supported on a heatable platen 20 in a vessel 10 having a sealed removable lid 11. Valve 17 is set so that pipe 16 communicates with a connector 18 of a vacuum pump and as air is evacuated from the vessel, heat is supplied to platen 20. When the top layer of polythene is semi-liquid, valve 17 is set to connect the vessel with the atmosphere via pipe 19 and the polythene is forced into a solid slab around the wire reinforcement 22. If necessary an inert gas may be applied to pipe 19 instead of air and cooling may later be effected by passing water through plates 20 or flooding the vessel 10 with water.

Title: Improvements in or relating to the preparation of adsorbent agents for gases
IPC: C01B31/08
Filed: 1950-09-14
Abstract: Activated carbon is prepared from acid sludge coke by treating it with steam or carbon dioxide or gases containing carbon-dioxide such as flue gas, at a temperature of 1350 to 1800 DEG F until a yield of above 50 per cent and below 60 per cent of activated carbon by weight of coke employed, is obtained in the case of steam treatment or above 40 per cent and below 50 per cent in the case of carbon dioxide treatment.  Treatment times may range from 10 minutes to 3 hours. Activation is preferably effected by employing a fluidized bed.  The resulting activated carbon is especially suited for the recovery of C2 and C3 hydrocarbons from refining fuel gas, to the recovery of light ends for low pressure catalyst cracking gases, to the separation of methane from nitrogen and the recovery of acetylene from the gases of the Wulff process.  Higher molecular weight hydrocarbons are preferentially absorbed from a mixture of gaseous hydrocarbons by the activated carbon, and data is given for the selectivity in the separation of propane from a mixture thereof with ethylene.
