Abstract: 1346904 Active filters TELEFONAKTIEBOLAGET L M ERICSSON 14 May 1971 [14 May 1970 3 March 1971] 15102/71 Heading H3U The effects of loss resistance in a filter F comprising inductance is reduced by modulating the input signal with an exponentially decaying signal. In a frequency changing filter, a sawtooth generator EG produces a repetitive decaying exponential signal which is mixed with the input frequency changer signal W a  before being applied to the input mixer M a . Generator EG also produces a similar repetitive rising exponential signal which is similarly mixed with the signal applied to the output mixer M b . If frequency changing is not required, the sawtooth signals are applied directly to input and output mixers. In a modification, Fig. 7 (not shown), a delay (# a ) is introduced between the generator EG and mixer Mb to compensate for delay in the filter F.

Abstract: 828,923. Gas-producers. HEURTEY & CIE. May 16, 1956 [May 23, 1955], No. 15195/56. Class 55 (1). In a complete gasifier in which a shaft 1 is surmounted by a retort 2 and part of the " poor gas " produced in shaft 1 is taken off through piping 6 whilst the remainder flows through the retort 2 and the resulting enriched gas flows out through piping 12, the ratio of enriched gas flow to " poor gas " flow is maintained substantially constant for a given output. The " poor gas " flowing through piping 6 is purified at 7, passes through a valve 9 and flowmeter 10 to a mixing chamber 11. The enriched gas similarly passes through a purifying apparatus 13, valve 14 and flowmeter 15 to the chamber 11. The indications of flowmeters 10, 15 are fed through lines 16, 17, to a quotient meter 18 which through line 19 and motor 20 controls valve 9. The quotient meter 18 also controls valve 14 through motor 21 for use when, although valve 9 is fully open, there is still an excess flow of enriched gas. In order that the flow ratio may vary as a function of the gas output, the meter 18 may be connected through line 22 to the motor 24 which controls the air blast valve 23, so that a correction is applied to the meter 18 depending on the setting of valve 23.

Title: Process for producing multilayer colour negatives containing masking images for colour correction purposes
IPC: G03C7/18
Filed: 1947-06-10
Abstract: 637,876. Colour photography. GENERAL ANILINE & FILM CORPORATION. June 10, 1947, No. 15284. Convention date, Oct. 16, 1946. [Class 98 (ii)] Subtractively coloured negatives incorporating correction printing masks are made by exposing, to a coloured object, a multilayer film having silver halide layers, the halide consisting substantially of bromide, sensitized respectively to the blue, green and red regions of the spectrum and containing colour formers ; colour developing, selectively fixing the residual silver halide in the blue sensitive layer, con. verting the remaining light-sensitive silver halides in the other layers into masking images of metallic silver, or of light insensitive silver sulphide or iodide, and removing the silver formed in situ with the colour developed images. The multilayer film is of normal type, as described in numerous Specifications and after exposure and colour development it is treated in an aqueous bath containing ammonium or sodium thiosulphate and an alkali sulphate, an alcohol, sugar or glycerin to remove silver halide from the upper most layer only ; after which, in the one modification of the invention all the silver present is bleached to silver chloride as by a potassium ferricyanide-sodium chloride bath and this silver chloride is removed by aqueous alkali sulphite, ammonium chloride or ammonia ; the film is then reexposed to light, developed in a black and white developer, washed, fixed and dried to provide masking images of silver ; and in the other modification the film is treated in an alkali iodide or sulphide bath to convert the residual silver halides to silver iodide or sulphide masking images without re-exposure, and in this case the metallic silver is removed by selective bleaching and fixing either prior to or after production of the silver iodide or sulphide masks. In either modification it is desirable, after colour development, to continue development with a black and white develop to achieve gamma infinity in all three layers, as described and claimed in Specification 637,865. The invention is compared with that of Specification 541,266, which also produces masks in the green and red sensitive layers of multicolour film, but which has the restriction that the colour sensitivity of these layers must not be destroyed in the bleaching step. Specifications 436,587, 458,400, 465,823, 471,520, 524,154, 524,554, 524,555, 527,283, 540,365, 540,366, 540,367, 540,368, 540,525, and 637,879, also are referred to.

Abstract: 727,773. Automatic exchange systems. STAATSBEDRIJF DER POSTERIJEN TELEGRAPHIE EN TELEFONIE. June 4, 1953 [June 9, 1952], No. 15461/53. Class 40 (4). A magnetic drum is used to register metering impulses. When a call is made a metering impulse is applied to an adding circuit at a time position corresponding to the subscriber's number and at the same time the old metering total is read from the drum and also fed to the adding circuit. The new total is then entered on the drum. Impulse generator IV1, magnetic drum MT and cam contacts 11, 12 are synchronized. When answering contacts ba close, A operates to the next closure of contacts 11 followed by B after nearly one revolution of the drum to send a metering impulse over line finder OZ to make tube 5 conduct at the instant when IV1 marks the appropriate units, tens and hundreds leads x, y, z. The tube 5 sends a pulse through gate TP1 to the adding device OD while the old total for the calling subscriber is read at AK and simultaneously passed through gate IP2 to the adding device. The new total is entered on the drum by recording head SK. Multiple-fee metering. In a modification for dealing with variable tariffs, the upper righthand part of Fig. 1 is replaced by Fig. 3. According to the zone one of contacts zr-zc is closed, za corresponding to the most expensive zone. After the answering contacts ba close, SA energizes over segment II or IV of commutator A which with B-E rotates once every 5 seconds whereas the drum rotates in 1“ seconds. SA steps its wipers sa to contacts 2 to energize T, which registers the first fee. Commutator C then controls the stepping of wipers sa to contacts 3, 4 and-5, T energizing again on the last under the control of commutator C, D or E according to the zone, the time of operation of T being varied by the varied positions I, II, IV of the conducting segments of the commutators. At some time during this energization of T the calling line is connected via the timing circuit of Fig. 1 to the drum and adding device OD. The operative commutator also controls one of impulse gates IP3-IP5 whereby the metering pulse passes from IP1 to IP3 without delay, through D1 and IP4 with a delay of 2n m. sees., or through D1, D2 and IP5 with a delay of 3n m. sees., when n m. sees. is the delay between the registration of successive digits on the binary system on the drum. By this means on the first, second or fourth rotation of the drum C, D or E enters a metering fee of 1, 4 or 8 units respectively into the adding device OD, which as in Fig. 1, also receives the old total and then enters the new total on the drum. Wipers sa then step on to the sixth contacts to energize SB, which reenergizes every 5 seconds so that wipers sb step over contacts tc. Contacts tc are connected to commutator C in such a manner that for the three zones T is energized every 10, 30 or 60 seconds respectively, while the connection is maintained.
