Title: Process for the production of anhydrous stannic chloride from metals containing tin
IPC: C01G19/08
Filed: 1929-01-07
Abstract: 304,282. Favre, G. A., (Assignee of @oriany, J.). Jan. 18, 1928, [Convention date]. Stannic and other metallic chlorides. - Metallic materials, such as alloys, containing tin are treated in the molten state, say at 900‹ C.. with chlorine with or without pressure. Volatilized chlorides, for instance those of iron, aluminium, and antimony. are separated by fractional condensation from the stannic chloride before the latter is condensed. Unvolatilized' chlorides, for instance those of lead and copper, are run off from the surface of the melt. Other metals referred to are silver, gold, molybdenum, and nickel. As shown in Fig. 2, the melt s in a container A may be supplied continuously with metal through a tube a, be heated initially by a burner p, and be cooled, if necessary, when the reaction has started, by a jacket m. Chlorine is supplied through tubes q which may be of quartz. Molten chlorides collect above a partition c provided with openings d to allow solid particles to return to the melt, and are tapped out through a tube e. Volatilized chlorides after passing round a baffle plate i pass through an outlet B to a series of condensing chambers which may contain substances to combine with any escaping chlorine. In a preferred form, a cooling chamber and two condensing towers are used, followed by a cooling- coil in which the stannic chloride is condensed. A slightly modified form of apparatus is shown and described.

Title: Process for treating aluminium foil
IPC: C25D5/44
Filed: 1972-01-06
Abstract: 1415653 Chromium plating A1 foil for lithographic printing plates J E THORPE 22 March 1973 [6 Jan 1972] 689/72 Heading C7B Aluminium foil having a coating of hydrophilic chromium for use in production of lithographic printing plates is produced by continuous passage of the foil through a series of treatment tanks for cleaning; optionally electrolytically etching and further cleaning with nitric acid; coating with a metal to which the next layer will adhere, e.g. Zu, e.g. deposited from a zinc oxide bath or deposited electrolytically from a cyanide bath; optionally plating with copper e.g. from a pyrophosphate bath, and thereafter electro-plating with hydrophilic chromium. The chromium may be deposited using interrupted D.C. current using a CrO 3 /H 2  SO 4  bath. A layer of light-sensitive material may then be applied. Without the copper layer this acts as the ink receptive layer of the lithographic plate, whilst with the copper layer the photo-resist acts as a stencil for etching the chromium to form a bi-metallic Cr/Cu lithographic plate.

Title: Improvements in or relating to converters
IPC: H02M7/12
Filed: 1970-01-06
Abstract: 1,270,513. Protecting converters. HITACHI Ltd. 6 Jan., 1970 [8 Jan., 1969], No. 699/70. Heading H2F. A method of protecting a series and/or parallel arrangement of thyristors in one arm of a converter comprising detecting the time interval from the time when the arm becomes non- conductive to the time when an inverse voltage disappears from said arm, comparing said time interval with a predetermined value and firing the thyristors of said arm upon application of forward voltage, when the time interval is shorter than the predetermined value. Fig. 4 shows a series arrangement of thyristors 11 ... 1n forming one arm of a 3-phase bridge (Fig. 2, not shown) which are normally triggered at an appropriate point in the anode voltage waveform by pulses from an amplifier 53. The anode waveform is reduced by a potential divider 41, 42, clipped by Zener diode 43 and applied to a circuit 44 which produces a pulse corresponding to the duration of negative excursions of the anode voltage. This pulse is differentiated at 45, the negative differentiated pulse triggering a monostable circuit 48 which energizes an AND gate 49 for a period corresponding to the minimum allowable margin angle. If the anode voltage changes polarity during this time (as shown in Fig. 5a) the positive differentiated pulse will be passed by diode 47 and AND gate 49 to an OR gate 50 which triggers the pulse amplifier 53 so as to turn on all thyristors 11 ... 1n. This action prevents excess voltage being applied across certain thyristors which would otherwise be non-conductive. Fig. 5b shows that the protection circuit is inoperative if the margin angle is adequate. Fig. 6 shows an arrangement for protecting inverters and comprises a slicer 65 fed from current transformers in the A.C. output lines and a further slicer 69 fed from a transformer across the output. Figs. 9 and 10 (not shown) relate to an arrangement involving a further monostable circuit which turns on all the thyristors of a series chain if the time interval from zero current to the time of a firing pulse having a lag of 180 degrees is not greater than a predetermined value. The invention is also applicable to the protection of parallel groups of thyristors.

Title: Improvements in decoders for binary data signals
IPC: H04L25/49
Filed: 1970-01-07
Abstract: 1,241,641. Data storage. INTERNATIONAL BUSINESS MACHINES CORP. 7 Jan., 1970 [14 Jan., 1969], No. 755/70. Heading G4C. A decoder for input binary data signals includes first integrating means for integrating an input signal with respect to a reference signal generated in response to polarity changes in the input signal, second integrating means for integrating the input signal, and comparison means for indicating a binary value in response to a comparison of the results of the two integrations. Binary data from a magnetic tape, drum, disc, strip or communications channel, is differentiated and limited to provide data signals in true and complement form having a midcell transistion for each " 1 " and a start-of-cell transition for each " 0 " not following a " 1 ". Each transistion produces a pulse from a peak pulser which is used to synchronize a sawtooth generator so that the sawtooth has a zerocrossing at each cell centre and cell boundary. Each zero-crossing produces a " half-period " pulse, from which a reference square-wave having one cycle in each bit cell is produced in true complement form and fed to a pair of " ones " integrators together with the true and complement data signals from the limiter. One integrator charges when the data and reference have the same level and the other when they have opposite levels. The level of the integrator which has charged the most is supplied to a voltage comparator and compared with a similar signal from a pair of " zeros " integrators which however have been integrating the two levels of the data signal respectively, without regard to the reference square-wave. The comparator output, indicating " 1 " or " 0 ", is gated out at the end of each bit cell (just) after which the integrators are reset, under control of a signal derived from the " half-period " pulses. An error indication may be given if successive adjacent " 1 "s are not indicated by the two " ones integrators alternately, or successive adjacent " 0 "s are not indicated by the two " zeros " integrators alternately. The invention can also be used with the data format which differs from the above by omitting alternate transitions in a sequence of successive " 0 "s, or that of double frequency encoding, or NRZ or NRZI. In the ease of NRZI, the integration period could last from the centre of one bit cell to the centre of the next-but-one cell. In formats characterized by unequal peak shift of data transitions as compared with clock transitions, the outputs of the " ones " integrators or the " zeros " integrators, as appropriate, could be increased slightly to compensate. Each pair of integrators could be replaced by a single integrator chargeable in both directions.

Title: Improvements in or relating to the charging of coal into coke-ovens
IPC: C10B31/04
Filed: 1925-01-12
Abstract: 227,470. Collin & Co., and Schaefer, J. Jan. 12, 1924, [Convention date]. Charging.-In the charging of coke-ovens the fuel is delivered with such velocity that the charge is compressed into a dense cake. An apparatus suitable for the charging of vertical coke-ovens comprises a hopper e having lower and upper compartments e<1>, e<2>, which are emptied in turn, so that all parts of the charge have to drop some distance during the filling operation. The charge is maintained under pressure within the retort by a weight c carried by the oven closure in such manner that it can rise as the charge expands. The weight is formed with passages d for allowing free escape of gas. The charging opening is of the full crosssectional area of the oven and the closure may be made in sections and strengthening by ribs. As alternatives to the arrangement shown, the hopper may be raised during the charging operation, or the charge may be delivered by mechanical projectors.

Abstract: 509,154. Degreasing metal articles. HOOD, N. R., SPENCER, S. B., and IMPERIAL CHEMICAL INDUSTRIES, Ltd. Jan. 11, 1938, No. 941. [Class 91] Apparatus for degreasing metal sheets consists of a carrier on which the sheets are arranged radially to the axis, and a solventcontaining chamber, in which the' carrier rotates axially. The metal sheets 1 are fed on to the spider 2 whence they drop on to the conveyer 5 and are carried to the ball bearings 8, 9 which direct the sheets between the sets of guides 17 of the carrier which rotates in the chamber. The base of the chamber is heated by coils 28 to vaporize the solvent. Condensing coils 12 in the upper part of the chamber condense the solvent and limit the upper level of the solvent. A guide 10 prevents the sheets from slipping out of the guides during rotation. The carrier is rotated step-by-step by the chain-wheel 16, chain 18, wheel 19, eccentric 20, link 21, arm 22, pawl 23 and ratchet-wheel 24. The axis 7 of the carrier is hollow and houses the supply pipes 11, 11A from which solvent is squirted on to the plates. It may also house a cooling coil 37 for condensing and recovering solvent. The plates make a circuit and are automatically removed by pairs of jaw clips 41 operated in synchronism with the carrier by the wheel 16. Specification 314,912, [Class 91], is referred to.

IPC: H03M1/08
Filed: 1981-01-07
Abstract: PURPOSE:To prevent fluctuation of a digital output signal, by keeping a latch circuit to latch state, if no analog output changes. CONSTITUTION:An analog output (e) from an analog signal source AS is converted into a digital signal (d) at an A/D converter ADC, and the digital signal (d) is applied to a display circuit or servo circuit DOS via a latch circuit LAT for the specified operation. An analog output (e) is applied also to an integral network INT from the AS, and an output (e') of the INT and the output (e) from the AS are inputted to a comparison circuit COM, which produces a control signal SL to keep ''0'' when a difference is produced between the (e') and (e) and to keep ''1'' when no differnce is present. Thus, the latch circuit LAT keeps latch state when the SL is at ''1'' and releases the latch when ''0''.

Filed: 1983-01-06
Abstract: PURPOSE:To separate a casting mold in a short time without damaging the product part from the product produced by multiple-piece casting by hammering a runner and transmitting many impact oscillations to the product part. CONSTITUTION:As a cam 9 rotates, an arm 5 and an impact hammer 4 are gradually forced upward, and gravity energy and the compressive energy of a coil spring 15 are accumulated. When a roller 8 is disengaged from a step part 9b, the accumulated energy is converted to the kinetic energy of the arm 5 and the hammer 4. Even if the supply of the energy from the spring 15 ends, the arm 5 and hammer 4 continue to move against a spring 11C until finally the hammer 4 strikes a casting 1 via a cap 3. The hammer 4 is escaped to provide a clearance C1 between the cap 3 and the hammer 4 by a lifting unit 11, so that the oscillation generated in the casting by the blow is not absorbed by the hammer 4. When the similar hammering operation is continued, the casting mold of a product part 1d is separated.
