Title: Method of injecting local oscillator signal into mixer
IPC: H03D9/06
Filed: 1947-12-19
Abstract: 642,549. Superheterodyne circuits. STANDARD TELEPHONES & CABLES, Ltd. Dec. 19, 1947, No. 33622. Convention date, Dec. 24, 1946. [Class 40 (v)] A signal mixer comprises a resonant circuit, a source of input signals, a source of local oscillator signals of relatively greater intensity, means for coupling the input signal source to the resonant circuit, and means for coupling the local oscillator signal source to the resonant circuit including a resistance having a value such that the amount of input signal energy injected into the local oscillator is negligible. As shown, the resonant coupling circuit is in the form of coaxial cylinders 9, 10, short circuited at one end, and connected by condensers 11 to the grid of a mixer valve 2. Condensers 13 tune the arrangement to the mid-frequency of the input signals from a source 3 which is coupled by concentric line 6, 7 connected to the resonator at a point which is distant from the valve 2 by a quarter wavelength at the input frequency. A local oscillator 4 is connected by lines 14, 15 to the resonator at a point distant from the valve 2 by a quarter wavelength at the local oscillator frequency. A resistance 18 is inserted of sufficient value to prevent an appreciable amount of input signal energy being lost in oscillator 4. Lines 14, 15 have such lengths as to match oscillator 4 to the load. Also, feeder 6, 7 is made threequarter wavelengths long at the local oscillator frequency so as to prevent any substantial injection of power from the local oscillator into the input signal circuits.

Title: Improved phosphorylated cellulose and method of obtaining it
Inventor: WELLS RONALD ALFRED
IPC: C08B5/00
Filed: 1957-11-01
Abstract: Cellulose is treated with phosphoric acid containing an excess of a basic nitrogen-containing compound employing a curing time such that substantially all the phosphorus in the phosphorylating agent becomes chemically combined with the cellulose.  The material thus obtained is converted from the salt form to the hydrogen form by treatment with a water-soluble acid, washed free from the acid with water and allowed to stand in contact with water.  In the example, strips of woodpulp cellulose are immersed for one minute in an aqueous solution containing 50% by weight of urea and 18% by weight of phosphoric acid and are squeezed until the ratio of the weight of absorbed liquor to cellulose has fallen to 3,0.  The strips are then heated for 2 1/2 hours in a current of air at 130 DEG C., immersed in water and broken down into pulp which is washed with water to remove water-soluble impurities.  The pulp is converted into an aqueous slurry and washed in an ion-exchange column with an excess of 2N aqueous sulphuric acid to replace the ammonium groups of the phosphorylated cellulose by hydrogen atoms.  The material in the column is then washed with an excess of distilled water until the pH of the effluent liquid has risen above 4 and the material is allowed to stand, immersed in the water in the column, for the three days.  The product of the invention has improved efficiency for the adsorption of thorium from acidic aqueous solutions containing phosphoric acid such as are obtained when monazite is treated with an aqueous acid. Specification 838,973 is referred to.

Title: Process for preventing frost from forming in coolers for the condensation of volatile substances from moist carrier gases
IPC: F25B47/00
Filed: 1954-12-01
Abstract: 758,903. Drying gases; refrigerating. FARBENFABRIKEN BAYER AKT.-GES. Dec. 1, 1954 [Dec. 5, 1953], No. 34827/54. Class 34(1). In a process for preventing frost forming on the cooling surfaces of coolers in which volatile substances, such as methylene chloride in the manufacture of photographic film, are condensed from moist carrier gases the gas mixture entering the cooler is pre-cooled before it reaches the cooling surfaces, without condensing the volatile substance, by contact with a counter current of an aqueous liquid with a lower vapour pressure than water, such as a solution of lithium bromide, until the dew point of the gas mixture is reduced to or below the temperature of the cooling surfaces. The water content of the lithium bromide solution which slowly rises owing to the water taken up from the gas mixture is kept constant by passing a small part of the solution through a heat exchanger to an evaporator. The gas mixture leaving the cooler comes into heat exchange with the used lithium bromide solution to warm the gas and cool the solution for re-use.
