[Class 98 (ii ] In material having several differently coloursensitized layers, an antihalation dyestuff is arranged behind the light-sensitive layer on which the incident light last falls and is coloured with a dyestuff whose colour is complementary to the colour-sensitivity of the last light-sensitive layer. If the layers are all on the side of the support, the antihalation layer may be between the lowest light-sensitive layer and the support or on the rear face of the film. The support itself may be coloured.

Title: Method of making iron chromium alloys
IPC: C21C7/00
Filed: 1925-09-03
Abstract: 244,413. Penniman, W. B. B., and Shackelford, E. J. Dec. 11, 1924. [Convention date]. No Patent granted (Sealing fee not paid). Alloys.-A process for making low-carbon ironchromium alloys, which may be stainless iron or steel or ferro-chromium, comprises successively charging and reducing quantities of chromium ore in contact with a reception slag over a molten iron or steel bath, removing the slag, and supplying fresh slag material between the successive charges of ore mixture, decarburizing the molten alloy by means of an oxidizing slag, and finally deoxidizing the product. The temperature of the furnace is preferably varied with successive charges of ore mixture. A molten iron bath in a furnace, which is preferably electric, is covered with a reception slag of lime and fluorspar. A finely crushed mixture, free from dust, of ore, flux, and reducing agent which may be coke, petroleum coke, or anthracite, is fed to the surface of the bath, the slag which forms being removed when preferably about half the mixture has been added and reduced ; the remainder of the charge is then added and reduced and the slag removed as before.. After removal of the last smelting slag, a slag of lime and fluorspar is added and melted, whereupon chromium ore is added and the heating continued until the carbon content is sufficiently reduced. Deoxidizing material, which may be ferrosilicon or other alloy, is then added to the surface of the decarburizing slag, and when the desired result is attained the slag is removed and the metal is covered with powdered lime, after which it is tapped and cast. The Specification as open to inspection under Sect. 91 (3) (a) states also that ferrochromium made by other processes may be decarburized by the steps referred to above. This subject-matter does not appear in the Specification as accepted.

Title: Improvements relating to sound analysing equipment
IPC: G10L19/02
Filed: 1964-05-29
Abstract: 1,020,527. Automatic speech recognition. INTERNATIONAL BUSINESS MACHINES CORPORATION. May 29, 1964 [June 28, 1963], No. 22279/64. Heading G4R. In sound analysing apparatus the formant frequencies are found by applying the sound signal to a plurality of filters each responsive to one of a number of frequency bands, there being means for indicating which filter output has the maximum value compared with the outputs of the filters responsive to adjacent frequency bands. The signal from microphone 1, Fig. 1, is compressed in pre-amplifier 2 controlled by A.G.C. unit 35. The compressed signal passes to a bank of filters F1-F15. The top filter F1 responds to " noise," i.e. fricative or sibilant signals, and consists of a resonant L-C circuit. The other filters respond to narrow bands, the centre frequency of which is indicated for each. These circuits each comprise a twin-T filter network and a difference amplifier. The output of filter F1 is applied via a coupling capacitor 69 and inverter amplifier 70 to an integrating pulseshaper 130 which recognizes the presence of fricative sound frequencies. The outputs of filters F2-F15 are coupled to rectifiers R1- R14 and the outputs, representing the energy in that particular frequency band, are applied to balance detectors B1-B13. An output is provided from each balance detector on one of two leads depending on the relationship between the energies in the corresponding two adjacent channels. Gates 120 connected to adjacent balance detectors give an output to indicate a local maximum in the curve of energy distribution over the frequency bands. These maxima, which indicate the formants of the speech wave, are applied via integrating pulse shapers 130. In units 180 transients are detected and combined at 205 to obtain timing pulses for sampling the outputs in line drivers 200. The signals are entered in a matrix store 270 as in Specification 966,211. If the A.G.C. signal exceeds a certain value a lamp 36 lights. The signal is also applied to a slope detector 145, a positive or negative change exceeding a certain value passing a signal via unit 180 for entry into the matrix store.
