Title: Improvements in and relating to electrical resistance measuring apparatus
IPC: G01R17/10
Filed: 1946-04-04
Abstract: 610,282. Resistance measurements. GENERAL ELECTRIC CO., Ltd., BARSDORF, L. W., and ORCHARD, F. C. April 4, 1946, No. 10430. [Class 37] A Wheatsone bridge has three resistors arranged in three arms, a check switch for connecting a known resistance in the fourth arm and a test switch for connecting in this arm test terminals between which the resistance to be tested can be connected. The bridge shown is particularly suitable for testing the resistance of earth continuity conductors of installation, including metal conduit, metalsheathed cable, &c., the resistance between any point of which and the earth electrode may not exceed 1 ohm. Three resistors 1, 2, 3 of 0.6 ohms, each are connected in three arms of a Wheatstone bridge, a galvanometer 4 being connected in diagonal A, B and a battery 5 being connected across the diagonal C, D through the contacts 6 of a push-button check switch 7 or the contacts 9 of a push-button test switch 8. A resistor 12 of 1.5 ohms is connected between points A, C and test clips 16 are connected by leads 15 and terminals 13, 14 to points A, E. A standard resistor 11 of 1 ohm is connected between the points E, C. The check switch 7 is closed and the test clips 16 are connected together, whereby the resistor 11 in series with the test leads 15 is connected in parallel with the resistor 12. All four arms have then the same resistance and the bridge should be balanced. The check switch 7 is opened, the test clips 16 are connected to the resistor under test, and the test switch 8 is closed. The standard resistance 11 is thereby short circuited through the switch contacts 9, 10 and the resistor under test is connected in parallel with the resistor 12. If the resistor under test has the same value as the standard resistor 11 the bridge is balanced. Deflection of the galvanometer 4 indicates a value above or below the standard. A trimming resistor 17 may be connected between the resistors 1, 12 by which the bridge may be adjusted to compensate for unbalance due to the resistance of the leads 15 &c.

Patent GB-104688-A (GB)
IPC: C07K16/06
Abstract: 104,688. Elektro-Osmose Akt.-Ges. (Graf Schwerin Ges.). March 7, 1916, [Convention date]. Void [Published under Sect. 91 of the Act]. Anti-toxins and immunizing and like serums are purified by electric endosmose between diaphragms, of which the one in front of the cathode is neutral or feebly electro-negative, being made, for instance, of vegetable substance, parchment, or viscose, while the one before the anode is electro-positive, suitable materials being animal skin and chrome leather. A low electric pressure is applied, when acids and bases, together with extractives, migrate through the diaphragms. Globulins are precipitated in the middle compartement, and may be separated centrifugally before further treatment of the serum. A higher electric pressure may then be applied, causing migration of albumens and precipitation of fatty bodies and substances resembling cholesterol. This stage of the process may be assisted by addition of an alkali or organic base. The liquid in the electrode compartments is preferably frequently exchanged for fresh water during the process.

Abstract: 562,853. Directive wireless signalling. STANDARD TELEPHONES & CABLES, Ltd., and ARMSTRONG, L. J. HEATONJuly 30, 1942, No. 10700. [Class 40 (v)] A transmitter for an equi-signal overlapping beam guiding system comprises three linear antennµ A, B, C, the outer antennµ A, C being fed with currents of opposite phase and the centre antenna B with currents having a phase angle of 90 degrees or less with respect to the current in A or C, the field being varied in direction by changing the relative phase of the centre and outer antennµ from a phase lead to a phase lag or vice versa by means of a single make or break contact. The phase angle of the currents in A and B may be 90 degrees, this phase angle being reversed by a relay associated with B. Alternatively and preferably, the phase angle 'between A and B may be 45 degrees, this angle being changed by 90 degrees to change from a lag to lead and vice versa. The transmitter T is connected by an open line to the point D, the length of the open lines DA, DC being 1“ #, and that of DB being ¥ #. The connection to A is reversed, so that A and C are energised in opposite phase. Fig. 2 shows the supply and keying circuit. The transmitter supplies energy over transformer TR to line TD, the combination L1, C3 preventing " parallel " currents over the line. The keying currents are fed through coils L2, L3 over the line TD to energize relay W. The centre antenna B of 70 ohms resistance is shunted by an inductive reactance L4 of 70 ohms in series with a capacitive reactance C5 of 140 ohms, which is intermittently shortcircuited by the relay W to change the reactance from 70 ohms capacitive to 70 ohms inductive, thereby obtaining a phase change of 90 degrees in the centre antenna and thus varying the direction of transmission.
