Title: Improvements in electrical signalling systems and apparatus for use therein
IPC: H04M15/08
Filed: 1945-06-13
Abstract: 593,779. Automatic exchange equipment. AUTOMATIC TELEPHONE & ELECTRIC CO., Ltd., and BAKER, G. T. June 13, 1945, No. 14948. [Class 40 (iv)] In a line identification arrangement of the kind described in Specification 539,823 in which the metering wires of the lines are connected over pairs of non-linear resistances to wires to which code markings are applied, the resistance discs pertaining to each group of e.g. 100 lines are clamped together with metal connecting plates between them to form a compact unit. The unit or block shown has 5 columns each comprising 20 pairs of discs a, b which are clamped by means of six pairs of insulated rods extending between top and bottom clamp plates. The metal plates between the associated pairs a, b are connected to the metering wires, while the other intervening plates are connected alternately to units and tens marking wires U, T, the latter set being constituted as strips extending over all the columns. In a 10,000 line exchange in which there are 100 such blocks, the tens marking wires are commoned over all the blocks having the same thousands digit, while the units marking wires are commoned over all the blocks having the same hundreds digit, thus reducing the total number of marking wires required to 200. It is sometimes preferable to employ units or blocks having a different number of pairs of discs. The blocks may conveniently be mounted on the meter rack which has a number of plates each accommodating 40 meters, and each block then consists of 40 pairs of discs arranged in two columns. The advantages of longitudinal and transverse multipling can be retained by suitable arrangement of the connections to the metering wires.

Abstract: 708,735. Solvent extraction of rotenone. KAGEYAMA, I., YASAUMURA, J., and SATO, M. June 25 1951, No. 15048/51. Class 81(1) A cyclic process of extracting rotenone from cube root or derris root comprises treating said materials with monofluoro dichloromethane CH Cl2F, which is liquefied either by compression, by cooling or by simultaneous compression and cooling, bringing the liquid solvent so formed into contact with the root and dissolving out and extracting the rotenone therefrom, vaporizing the solvent to separate it from the extract by decreasing the pressure or by heating or by simultaneously heating and decompressing, repeating the cycle until the extraction is complete and removing the extracted rotenone. As shown, an extraction vessel 2 is connnected by means of suitable pipes and valves to a condenser 11, an evaporator 13 and a solvent tank 18. A cotton bag 1 containing the powdered root'is placed in the extraction vessel 2. The extraction vessel, condenser and evaporator are evacuated through valve 3. Solvent is allowed to pass from the tank 18 to the evaporator 13, where it is vaporized by the hot water or steam passing through pipe 14, and is then condensed' in the vessel 11 by the cold water circulating through pipe 12. The condensed solvent passes into the extraction vessel 3 and the extract siphons through 19 into the evaporator 13, where, the solvent is removed. The cycle is repeated until the root is exhausted when the solvent in the evaporator is passed to the solvent tank 18 by means of a compressor 17. Air is then introduced into the evaporator and the extract run off at 15.

Filed: 1974-04-09
Abstract: 1465846 Camera shutter control circuit NIPPON KOGAKU KK 9 April 1974 [10 April 1973 15682/74 Heading G2A A camera shutter control circuit has a memory capacitor 13a with one side connected to receive a voltage V1 proportional to a first exposure factor and the other side connected to receive a voltage V2 proportional to a second exposure factor, the capacitor 13a being connected between the inputs of a differential amplifier 5, 6 the output V5 of which is used to control shutter opening time. As shown, V1 is proportional to log brightness and V2 to log aperture and/or film speed. The circuit eliminates the effects of variations in power supply and ambient temperature and, since capacitor 13a stores the difference between V1 and V2 the maximum voltage it is required to store is low and therefore timing accuracy is increased. In Fig. 3 (not shown) a buffer circuit (14) is connected between one side of capacitor 13a and the differential amplifier.

Title: Arrangement for feeding a direct current motor
IPC: H02P7/00
Filed: 1973-04-03
Abstract: 1425236 Speed control of D.C. motors COMPAGNIE HONEYWELL BULL 3 April 1973 [10 April 1972] 15963/73 Heading H2J  A supply system for a D.C. motor comprises at least one control circuit connected on each side of the motor, each circuit including at least one power transistor, and a driving circuit controlling the conductivity of the power transistor of ;one control circuit as a function of the amplitude of a control signal whilst causing the power transistor of another control circuit to saturate thereby controlling the current through the motor.  As shown, the current through a motor M is controlled by four circuits I 1 -I 4 , each comprising two transistors T 1 -T 8 , and arranged in a bridge circuit with the motor connected across the diagonal AB, and the D.C. supply across the other diagonal C.D. Circuits I 1 , I 2  are controlled by drive transistors T 18 , T 19  and T 16  whilst circuits I 3 , I 4  are controlled by drive transistors T 17  T 20 . Due to the gain in T 17 , when a control signal is applied to a terminal 2, more current will flow through T 20  than T 17 . Thus transistors T 4 , T 8  controlled by T 20  will become saturated, while T 3 , T 7 , in an opposite bridge arm and controlled by T 17 , will have a variable degree of conductivity dependent upon the amplitude of the control signal applied to terminal 2. Thereby the motor speed and acceleration are controllable. The signal fed to terminal 2 causes current flow through the motor from B to A so that it rotates in the required direction. For braking the motor, the control signal is removed from 2 and applied to a terminal 1. If the latter signal input is maintained after the motor has stopped, rotation in the opposite direction will occur.
