Filed: 1941-05-02
Abstract: 549,111. Softening water. FROUDE, R. H. May 2, 1941. No. 5726. [Class 46] One raw water supply, or portion of a supply, is passed through a base-exchange softener and mixed in, or en route to, a lime softener with another raw water supply, or another portion of the supply, led direct to the lime softener so that permanent hardness is removed from the water supplied direct to the lime softener by the reaction of sodium. bicarbonate produced by the base-exchange and lime in the lime softener. The base-exchange softener may be arranged to feed an excess of sodium bicarbonate so as, to cause some free alkalinity in the final water. Sea water may be used to regenerate the base-exchange material.

Title: Period modulation circuit
IPC: H03K7/08
Filed: 1966-02-14
Abstract: 1,084,483. Pulse modulation circuits; transistor multivibrators. BELL & HOWELL CO. Feb. 14, 1966 [July 19, 1965], No. 6320/66. Headings H3T and H4L. In a pulse modulator in which the half-cycle period of the output signal changes in accordance with an input modulating signal, the input signal is supplied to the common emitter circuit of a pair of transistors 10, 12 connected as a multivibrator. The bases of the two transistors are clamped to earth by diodes 34, 36 respectively, and diodes 30, 32 conduct alternately to provide a constant amplitude output signal. In operation, when transistor 10 is conducting the capacitor 44 is charged to the potential set up by the voltage divider comprising resistors 24, 52, 54 and diode 48, the diode 34 being conducting and diode 46 biased off. Since capacitor 42 has been similarly charged in the previous cycle, when transistor 10 initially conducts the potential at the base of transistor. 12 is lowered in dependence on the charge on capacitor 42 together with the potential at the collector of transistor 10 as varied by the input signal Capacitor 42 is gradually discharged through resistor 40 until the condition of the two transistors is reversed and in this way the duration of one half-cycle is made proportional to the input signal level. If the transistors and diodes are of similar types such as silicon the circuit compensates for temperature changes, e.g. any changer in the base-to-emitter voltage oftransistor 10 with temperature is compensated by a corresponding change across diode 34.

The graduations upon the transparent sphere may take the form of a great circle with parallel small circles. Fig. 1 shows the construction wherein the three disks, of which two, H<1>, H<2> appear, have peripheral flanges H<4>, the material being wood or celluloid; this indicator maintains indications during inversion of an aircraft or other structure upon which the inclinometer is mounted, and is weighted to define a normal position. The spherical container is made in two halves with flanges A<1>, A<2>, secured together. Methylated spirit or an aqueous solution not readily frozen is employed as the liquid and its specific gravity is chosen to be equal to that of the indicator. Luminous paint may be employed to facilitate use at night.

The catalysts are preferably oxides or sulphides of metals of the 6th and 8th groups of the periodic system such as tungsten, molybdenum, cobalt, chromium, nickel and iron, and of vanadium; and they may be supported on activated charcoal, silica gel or alumina.  The hydrocarbons may be crude benzol, crude motor spirit, medium oil, having a boiling point up to 400 DEG  C.  Operating temperatures may be between 50 DEG and 240 DEG  C., hydrogenation being effected at a pressure of 10-100 atmospheres.

Gases, separating mixtures of.-To recover volatile liquids in a practically pure state from gases nearly or completely saturated therewith, the mixtures being substantially free from water vapour, a thin stream of water not more than sufficient to just saturate the mixture with water vapour is caused to flow in counter-current through the gas, the volatile liquid then being drawn off at the bottom. In an example dry air containing 1.3 per cent of acetic acid was passed up a column 240 cm. long and 2 cm. in diameter containing 3 mm. porcelain beads at the rate of 130 litres an hour, water heing supplied at the head of the column at the rate of 4 cc. per hour.
