Patent GB-859111-A (GB)
Title: Improvements in or relating to telephone subscriber sets using amplifiers
Inventor: LAMBOURN EDWARD HARRY
IPC: H04M1/58
Filed: 1956-08-31
Abstract: 859,111. Substation circuits. STANDARD TELEPHONES & CABLES Ltd. Aug. 30, 1957 [Aug. 31, 1956], No. 26730/56. Class 40 (4). Fig. 1 shows a circuit for amplifying a calling signal. Calling tone is supplied by a source SS at the exchange. Positive half-cycles flow through. C5, R8 so producing a pulse in the emitter-collector circuit and a corresponding pulse in the loud-speaker LS. During negative half-cycles the transistor does not conduct. In Fig. 3a terminal B feeds the emitter through the primary of T3 and the base through both windings of T3 and capacitor C7. Terminal A is connected to the primary of autotransformer T4. During the positive half-cycle of a calling signal the transistor conducts so charging capacitor C6 to reduce the potential on the base. In the negative half-cycles C6 discharges and the transistor does not conduct. The transistor may be biased to conduct on both positive and negative half-cycles to produce a Class A amplifier. In Fig. 4, alternate half-cycles induced by the output from the collector determine the potential across C8 and hence the potential of the emitter. Transistor TR, Fig. 6, amplifies speech as well as incoming calling signals. Calling signals from the exchange circulate in the base-emitter circuit to produce signals in the base-collector circuit over contacts CS2 and winding a of autotransformer T7, so inducing signals in winding c and loud-speaker LS. When the subscriber answers cradle switches CS1-CS5 are reversed and transistor TR is biased to conductive condition by the potential applied to its base over R13. Speech signals generated by transmitter TX are amplified and appear in the basecollector circuit and auto-transformer. Induced currents are thus applied to line. Fig. 8 involves the use of a Zener diode Z which maintains the current flowing in the subscriber's loop substantially constant and independent of loop resistance. Resistor R3 compensates for the effects of change of temperature on the transistor. The dialling circuits of Figs. 6 and 8 are suitable for use with electronic exchanges and produce pulses of changed potential instead of break and make.

Patent GB-272970-A (GB)
Abstract: 272,970. Cooper, C., Henshaw, D. M., and Holmes & Co., Ltd., W. C. Dec. 16, 1925. Ammonia, distilling. - Water vapour is separated from ammonia or a gas containing ammonia by passing the gas in countercurrent to a liquid such as potassium carbonate solution which has an affinity for water. The solution is maintained at 90-100‹ C. to reduce absorption of ammonia. The treatment may be carried out by passing the gas upwards through a tower containing trays with overflow devices down which the solution flows. The solution may be concentrated for use again by causing it to flow down the outer surface of the tower. Gases from an ammonia still, after separation of water vapours, may be passed into acids to form ammonium salts or where they contain carbon dioxide may be cooled for the separation of ammonium carbonate.

Title: Improvements relating to the actuation of controllers for electric motors
IPC: B60L15/34
Filed: 1935-10-04
Abstract: 463,568. Hydraulic transmission of power. SMITHSON & CO., Ltd., J. G., and SMITHSON, J. G. Oct. 4,1935, Nos. 27418/35 and 18230/36. [Class 69 (ii)] [Also in Groups XXXVII and XXVIII] An electric circuit cam-shaft controller is operated by a piston g working in a cylinder h against a spring 6, liquid being forced into the cylinder from a reservoir p by means of a plunger pump l driven by an electric motor k. The controller comprises cams c mounted on a shaft b and co-operating with rollers 4 on switch arms, the cams being formed with abruptly curved parts 3. With the pump l working, and an electromagnet y energized to close a byepass valve x, the piston g is operated until the part 3 of a cam c engages its roller 4, whereupon the movement of the piston g is arrested, and pressure built up in a chamber t which contains-a spring-pressed piston u and is in communication with the passage i leading from the reservoir p to the cylinder h. When sufficient pressure has been built up it overcomes the resistance offered by the cam c and the roller 4, and effects a relatively rapid movement of the piston g and a quick step movement of the controller. The operation is repeated for each step movement of the controller. An adjustable stop 8 may be provided for the piston u. To effect a return movement of the controller the electromagnet y is deenergized to open the valve x and permit the spring 6 to return the piston. The stepmovement of the controller may be arrested by stopping the motor k, and the motor k may be stopped by a switch operated when the piston g has moved its full amount. The speed of the pump l may be varied or an adjustable valve may be provided in the passage i. The plunger pump may alternatively be operated by hand or foot.

Abstract: 274,799. Raffinerie Tirlemontoise Soc. Anon. July 24, 1926, [Convention date]. Refining sugar.-An increased yield of sugar crystals is obtained from massecuite by cooling the massecuite to a pasty or plastic condition, in which it is not normally adapted for centrifugal treatment, and then separating it into crystals and syrup in centrifuges operating at considerably greater centrifugal force than those previously employed. The centrifugal force may. for example, be 1500 to 6000 and more times the weight of the mass treated, and may be obtained by increasing the speed or the diameter of the centrifuge drum. The water content of the massecuite may be reduced by evaporation &c. at or subsequent to the cooling.
