Patent GB-1603578-A (GB)
Title: System and method for identifying samples having conductive properties
IPC: G01N27/72
Filed: 1978-05-11
Abstract: The primary coil (14) of a coil arrangement (14, 16) is fed by a frequency generator (12) having selectable frequencies. The secondary coil (16) is connected to a phase detector (18) which detects phase changes occurring in the signal of the secondary coil (16) when a conductive object (20) is brought into the magnetic field of the primary coil (14). The pure resistance component (R) of the impedance change occurring by bringing the object (20) into the previously calibrated coil arrangement, divided by the frequency (F) supplied changes as a function of frequency and discloses a single peak value at a single characteristic frequency value. These values are compared with characteristic data of known objects, for example stored in a computer. Both values depend on the type and the geometry of the conductive object. For an object made of metal, the characteristic frequency is proportional to the specific resistance of the object divided by its cross-sectional area. Using the device according to the invention, it is possible to obtain accurate information on the type of a conductive object, for example a hidden handgun at the airport. It is also possible to identify various metallic components, if present, in an object. Conductive solutions, animal tissues and others can also be identified. <IMAGE>

Abstract: The invention comprises a method of hydrogenating perfluorocyclobutene in presence of iodine to give 1 : 1 : 2 : 3 : 4 : 4-hexafluorobutane, followed if desired by indirectly dehydrogenating the product to give perfluorobutadiene.  The latter process may be by brominating or chlorinating the hexafluoro compound to give 1 : 2 : 3 : 4-tetrabromo- or tetrachlorohexafluorobutane, followed by dehalogenation, or to form a dibromo- or dichloro-hexafluorobutane and dehydrohalogenating the product, and the invention comprises also the preparation of the intermediate products of each of these processes.  In examples, the hydrogenation of perfluorocyclobutene under various conditions in an autoclave is described, iodine being used as catalyst to give 1 : 1 : 2 : 3 : 4 : 4-hexafluorobutane; the product is chlorinated to the 1 : 2 : 3 : 4-tetrachloro compound, followed by dechlorination to perfluorobutadiene, with zinc in alcohol; chlorination of the first product to a dichlorohexafluorobutane is also described. Perfluorocyclobutene is prepared by heating trifluorochloroethylene at about 200 DEG  C. to form 1 : 2-dichlorohexafluorocyclobutane and dechlorinating the latter compound.

Title: Electric regulators
IPC: H02P9/26
Filed: 1926-08-03
Abstract: 275,784. Beatty, W. E., (Bell Telephone Laboratories, Inc.). Aug. 3, 1926. Regulation, automatic.-The voltage of a generator 3 is kept constant by two thermionic valves 6, 7, the first of which is run at saturation. Upon increase of voltage, the filament of the first valve gets brighter causing a larger anode current and therefore, a bigger P.D across an anode resistance 11. The potential of the grid of the second valve is thereby lowered, causing a smaller current to flow in its anode circuit which includes an auxiliary field 5 and thereby reduces the voltage of the generator. By connecting the field 5 to a tapping on a resistance 9 in series with the filament of the first valve, a decrease in field current causes an increase in brightness of the filament, thus giving a cumulative regulating effect. By adjusting the position of the tapping, over, flat, or under regulation can be obtained. Transient voltage variations are corrected by a transformer 17, the primary of which is connected across the mains and the secondary is included in the grid circuit of the second valve. Modifications are described in which the anode battery 10 and cathode battery 16 are replaced by a source of AC, rectified where necessary. In one modification the transformer 17 is replaced by a condenser shunted across the portion 9<a> of the resistance. The device can also be applied to AC generators.

Abstract: 684,637. Automatic exchange systems. GENERAL ELECTRIC CO., Ltd., and SCOWCROFT, J. June 7, 1951 [Aug. 2, 1950], No. 19332/50. Class 40 (iv). In a system in which a partyline subscriber is required to press a button to complete a calling loop, the button also controls ah impulse - sender which sends a number of impulses characteristic of the caller. The calling loop is closed at springs LM2 which lock until the receiver is replaced, a condenser K being cut out. The impulse-sender LM1, which is the subject of Specification 684,657, is wound up by the depression of the button and emits impulses on the return movement after the button is released, the instruments and normal dial D1 being cut out meanwhile at the lefthand springs. At the exchange, relay A energizes in the calling loop, followed by B, H, and the forward loop to the line circuit is closed. The impulses from LM1 step the switch DM to select the caller's meter, the forward loop being maintained by series relay CA. Subsequent dialled digits are repeated forward in the usual manner. When the party-line is called, code ringing is applied by relay RG and the called subscriber depresses his button to trip the ringing. If setting of the switch DM is not required when a call is answered the impulses from LM1 may be nullified by a relay dependent on RG or by a polarized relay at the substation.
