Title: Electrical circuit arrangements for measuring time distortion  in pulse signals
IPC: G01R13/20
Filed: 1973-09-17
Abstract: 1425515 Telegraphy; distortion measurement SIEMENS AG 17 Sept 1973 [29 Sept 1972] 43509/73 Addition to 1161951 Heading H4P The pulse distortion measuring circuit disclosed in the parent Specification 1,161,951 is modified in order that maximum time deviations, as well as instantaneous ones, may be indicated. The counter Z1 of the original invention performs one counting cycle each theoretical duration of a telegraphic signal element. At each element flank a pulse M derived therefrom causes the counter value to be connected to stores SP1, SP2 which hold the maximum value of leading distortion in SP1 and lagging distortion in SP2. Comparators V1, V2 are upgraded when values in SP1, SP2 respectively are higher than previous values.  If it is desired to display the actual element distortion a switch S is set to position 0 causing switch S1 to open and switch S2 to close connecting measuring pulse M to a store SP; a switch US also connects counter Z1 thus at each element flank, count of Z1 is received in SP and is displayed on the screen of an oscilloscope (not shown). To display maximum values, switch S is set to position 1 hence switch US is recontrolled by pulse generator HT which alternately switches output of SP1, SP2 to SP. To ensure synchronization switch S2 is moved to a position whereby HT supplies SP. SP is followed by a D/A converter DAU which controls an indicating deflection on a cathode-ray tube B. A¸2 divider FT drives switch US so that between two timing pulses a pulse occurs which switches US from one store to the other. In an alternative arrangement values stored in SP1, SP2 may be displayed on a device other than an oscilloscope; the device may be supplied directly from SP1, SP2 either directly or through a further store (not shown). The further display means may conveniently comprise a set of luminescent diodes. After a measuring period stores SP1, SP2 may be cleared by a reset key RT.

Title: Improvements in or relating to systems for charging electrical storage batteries and protective arrangements therefor
IPC: H02H3/36
Filed: 1969-09-10
Abstract: 1,223,535. Battery-charging systems. SOC. GENERALE DE CONSTRUCTIONS ELECTRIQUES ET MECANIQUES (ALSTHOM). 10 Sept., 1969 [18 Oct., 1968], No. 44667/69. Heading H2H. A battery-charging circuit includes a circuitbreaker which is closed by a coil only when the voltage of a charging generator is equal to or slightly greater than the battery voltage. The coil is controlled by a saturable transformer. As shown in Fig. 1, the transformer 1 has a primary winding 3, secondary winding 4, and control windings 5, 6. The secondary is connected to the operating coil 9 through a rectifier bridge 8. In use, an A.C. supply is connected to the primary 3, and the control windings, which are identical except for their polarity, are supplied with D.C. signals proportional to the generator voltage and battery voltage respectively. When the currents in the control windings 5, 6 are approximately equal, their effects cancel out and the arrangement acts as a normal transformer, supplying current to operate the coil 9. If, however, the currents in the windings 5 and 6 differ by more than a certain value, then the transformer 1 saturates and no secondary output is obtained. The extent of the range of voltage difference between the windings 5 and 6 for which the relay can operate is determined by the setting of a variable resistor 7 in the primary circuit, and this range can be shifted using variable resistors 10, 11 so that closure of the charging circuit is effected only when the generator and battery voltages are in a desired relationship.

Title: Method of incorporating a highly reactive material into molten steel
IPC: C21C7/04
Filed: 1975-10-30
Abstract: 1475247 Alloying steel JONES & LAUGHLIN STEEL CORP 30 Oct 1975 [11 Nov 1974] 44790/75 Heading C7D [Also in Division B3] In a method of alloying molten steel with highly reactive materials, such as rare earths, Al, Ti, and/or Zr, all of which have a high oxygen affinity and act as sulphide shape control agents, the following steps, (steps b and c not necessarily in the sequence shown) are employed (a) The steel is deoxidised; (b) A mixture of alkaline earth - reactive metal is added below the surface of the molten steel, and (c) the alloyed steel is teemed through a gaseous reducing atmosphere such as propane, butane, natural or coke oven gas, into a mould 'wherein  there is a gas generating material which vaporizes  to purge the mould of air and create a reducing  atmosphere.  The alkaline earth with which the reactive  material is mixed is selected from 2-8% Mg,  10-20% Ca or 10-20% Ba, with 10-20% Ca as  the preferred material. The function of the alka-  line earth is to tie-up any remaining oxygen present in the steel after deoxidation, usually with Si and/ or Al, and to vaporize and create a stirring of the steel bath to ensure uniform distribution of the  reactive metal. The reactive material may be  elemental or alloyed and is preferentially a rare  earth or mixture of misch metal and rare earth silicide. The gas generating: material placed in the mould prior to teeming may be a hydrocarbon  together with a fluxing agent which on casting provides a further cast to the molten steel. The hydrocarbon to flux ratio is 5-50% hydrocarbon 95-50% flux. A second embodiment of the process may con-  sist of  (1) deoxidation  (2) teeming as before through a gaseous atmos-  phere into a mould with the gas generating  material therein,  (3) allowing the mould to stand for 2-4 minutes to permit a shell to solidify and allow any  inclusions to float out, and  (4) adding the alkaline-earth-reactive material  mixture, possibly in briquetted form, by  plunging it below the surface of the molten  steel in the mould.  In this embodiment, the alkaline earth may be selected from 0À5-2% Mg, 5-10% Ca, 5-10% Ba, the reactive material being unchanged from the first embodiment.  In a third embodiment, the alkaline earthreactive materials may be added to the steel in the mould where it is being teemed through the gas-  eous reducing atmosphere. The materials may be added consecutively or simultaneously, and if added consecutively, the alkaline earth should be added first.
