Title: Method and means for determining the transmission equivalent of an electrical circuit
IPC: H04B3/46
Filed: 1920-08-13
Abstract: 171,470. Western Electric Co., Ltd., (Western Electric Co., Inc.). Aug. 13, 1920. Transmission equivalent of electric circuits, measuring. - The transmission equivalent or efficiency of electrical devices and circuits, such as telephone lines, is measured in terms of miles of standard cable. The apparatus consists essentially of a source of current 1, a variable measuring artificial line 13, and an ammeter or other current indicator 21. The line L to be measured is connected for the test in series with the line 13 between the source 1 and the ammeter 21. The test consists in varying the known transmission equivalent of the line 13 by means of a resistance device 13<a>, so that the equivalent of the combined line 13 is made equal to the original equivalent of the line 13 alone as indicated by equal current in the ammeter. The dial 13<a> of the resistance device is calibrated in miles of standard cable so that the extent of variation may be read directly and the equivalent of the line L deduced. The generator 1 may be of any suitable type, such as a vacuumtube oscillator, a single-frequency tone-generator of the vibrative-reed type, or a frequency-band generator giving results approximately to the conditions obtaining for voice currents. Amplifying means 16, 13, 19 are included between one artificial line and the ammeter with which means is associated in circuit for preventing current in excess of a predetermined value from reaching the ammeter 21. A rectifier 20 is included, so that a direct current instrument may be employed. Filtering circuits 17 are also included to prevent currents of a character other than that of the source from reaching the ammeter, their relation being such that at least one amplifier is included between the line to be measured and the ammeter. To reduce the number of adjustments of the resistance device when a large number of measurements is to be made, and also to provide for the measurement of lines of which the transmission equivalent is outside the range of the artificial line 13, a calibrating line 12 is used. Switches 11, 14 are provided to enable the lines 12, 13 to be interchanged at will. Both lines have a constant impedance and the line 12 a constant transmission equivalent which may be more or less than the maximum, equivalent of the line 13, the extent of the difference being taken into account in deducing the transmission equivalent of the line under test from the reading of the resistance device. The Figure shows the arrangements when a line from an office A is to be tested by apparatus at an office B, a source of current 1<1> being provided at the latter office which is equivalent to the source 1 at office A. The nature and use of the auxiliary apparatus shown in the Figure are described in the Specification.

IPC: C25D17/14
Filed: 1962-06-25
Abstract: <PICT:0972048/C6-C7/1> An electrolytic "pen" consists of a reservoir of electrolyte 5 which flows downwards over the surface of an electrically insulated member forming a writing point 4, closely adjacent an electrode member 8 so that it extends within a very short distance above the metal surface 12 to be marked, an electric current flowing from the electrode through the film of electrolyte flowing over the writing point to the metal surface.

Filed: 1954-08-23
Abstract: 770,323. Motor vehicle driving gear. FERGUSON RESEARCH, Ltd., H. Aug. 9, 1955 [Aug. 23, 1954], No. 24414/54. Class 79(2). [Also in Group XXIV] In an all-wheel drive vehicle transmission having change-speed and/or reversing gearing and having differential gearing between the front and rear wheel drives, the over-running member of a one-way free-wheel is driven from the input of the change-speed and/or reverse gearing and the running member is connected to the output of the differential gearing. The output from a hydraulic torque converter drives a gear 11 meshing with a slightly larger gear 21 on a shaft 20, which shaft carries a sliding gear 22 and gears 23, 24 connectable to the shaft 20 through a synchro-mesh mechanism 29. The gears 22, 23, 24 are selectively connectable to gears 25, 26, 27 respectively to provide a threespeed drive to the planet carrier of a bevel gear differential, the runwheels 14F, 14R of which are connected to the front and rear propeller shafts 12F, 12R respectively. A cluster of idler gears (not shown) is interposable between gears 22, 25 to provide a reverse drive. The running member 31R of a one-way free-wheel is keyed to the propeller shaft 12B. A set of rollers 32R, accommodated between the member 31R and an over-running member 33R, is lightly urged into the wedging position by spring-pressed plungers 38. The over-running member 33R incorporates a gear 35 meshing with an equal size gear 36 keyed to shaft 20. A similar free-wheel 31F, 33F, 32F is connected between the shaft 12F and the gear 21. In operation under normal conditions the torque is equally divided between the front and rear shafts 12F, 12R and the overrunning members 32F, 33R rotate at a slightly higher speed, in the overrun direction, to the running members 31F, 31R. When front or rear wheel slippage occurs the relevant propeller shaft will accelerate and the free-wheel associated with that shaft will lock and prevent the differential action. In reverse drive the overrunning members will continue to rotate in the forward direction and free-wheel action will always occur. When a hydraulic torque converter is not employed, a dog clutch may be interposed between gear 11 and shaft 10 to allow towing of the vehicle.

The armature bias spring and the bar bias spring may be a common member and comprise two helical springs fitted between the pivot 9 and a fixed rod 14. When in the set positions the spring contact members 18. 19 apply a torque to the rocking member 10 to keep it in the corresponding set position; which positions may be adjusted by screws 25. 26.
