Abstract: 986, 520. Indicating extremes of amplitude. INTERNATIONAL BUSINESS MACHINES CORPORATION. Dec. 4, 1962 [Dec. 7, 1961], No. 45737/62. Heading G1U. [Also in Division G4] In speech recognition apparatus an indication of local amplitude extreme in a number of frequency channels is provided by applying each channel to a transistor adapted to respond to a local maximum, the output of any transistor which responds serving also to inhibit response of at least adjacent transistors. The speech signal from microphone 7 is applied to band-pass filters 8a-8n the outputs of which pass to detectors 10a-10n giving D.C. amplitudes proportional to the square of the input amplitudes. These signals are therefore measures of the power in the corresponding frequency band. The curve of Fig. 2 represents the power in the different frequency bands, each maximum being accompanied by smaller peaks on each side, relating to harmonics of the maximum frequency. The circuit is designed to respond only to the main maxima and to ignore all or some of the adjacent peaks. The outputs from detectors 10a- 10n are each applied to comparator transistors 11a-11n which tend to conduct. When the transistor, say 11b of the channel having a maximum, conducts the potential at point 13b increases and exceeds the amplitude of the adjacent peaks. Through resistors 14a and 14b the potential of points 13a and 13c is also raised sufficiently to prevent the transistors 11a and 11c conducting. At more remote points 13d-13n the effect of the conduction of transistor 11b is more attenuated due to the successive resistors 14c-14n and more remote transistors are not affected so that other local maximum may be detected in the same way. Those transistors which conduct energize relays 17a-17n through second transistors 16a-16n The output, Fig. 4 indicates the local maxima. These are called the "formants" of the signal. A modification having two comparator stages for detecting more widely differing maxima such as the one at f6.

Title: Improvements in transmission mechanism for motor vehicles
Filed: 1934-01-11
Abstract: 435,028. Controlling variable speed gearing; escapement mechanism. BROWN & SONS (HUDDERSFIELD), Ltd., D., and MERRITT, H. E., Lockwood, Huddersfield. Jan. 11, 1934, No. 1025. [Classes 80 (ii) and 80 (iv)] The longitudinal striking movement of a selector g is derived from the main clutch pedal of a motor-vehicle, whilst the movement for turning it into engagement with a selected one of a group of gear-engaging elements is derived from a spring escapementmechanism j, released when the clutch-pedal reaches the downward limit of its travel, to cause the selector g to move one step, the direction of which is determined by the direction of axial bias on a preselector-rod m, which energizes the escapement-spring j. The preselector-rod m may be biassed in one direction by a spring or a vacuum or pressure cylinder and in the other by the accelerator pedal, which latter may also act through a vacuum or pressure cylinder, so that release of the accelerator pedal causes the subsequent change to be upwards, whilst depression thereof causes it to be downwards. The fluid pressure cylinder preferably only acts when the clutch pedal is depressed. Whilst the clutch pedal is fully depressed, any desired gear can also be selected by a manual control lever. The gear-elements all move in the same direction, i.e. to the right of Fig. 4, for engagement. The selector g is mounted for rotation only, on a spring loaded rod h, which is moved axially by the clutch-pedal. Axial bias on the preselector rod m, which cannot turn, acts, through a screw-thread m<1>, to turn a sleeve k, connected by the torsion-spring j with a pinion il meshing slidably with the selector g. When the clutch pedal is depressed and the rod h approaches the neutralizing end of its travel, the sleeve k is locked by release of a spring-returned fixed peg k<3>, and subsequently the selector g is released from a fixed peg o engaging one of a series of holes in it. The spring then turns the selector one step, and on release of the clutch pedal the selector engages the new speed. The mechanism for limiting the rotation of the sleeves k and i<1> to one step, is shown in Fig. 6 and comprises loose intermediate flanged sleeves i<4> k<7>, each of which rigidly carries an axial pin i<3>, k<5>, supporting the ends of the spring j, and engaging notches of one steplength in all the other sleeves. When it is desired to select manually any gear other than the adjacent one, the pin k<3>, Fig. 4, is manually withdrawn so as to allow the sleeve k to be turned more than one step whilst the clutch is fully disengaged.

Abstract: 588,008. Cooling radiators for aircraft and motor vehicles. GEDDES, W. H., and SCHANKE, P. W. Jan. 16, 1945, No. 1292. Convention date, Dec. 14, 1943. [Class 64 (iii)] A temperature regulating device for fluids circulating round a cooling system under pressure, e.g., an oil cooler for use with an internal combustion engine, comprises a cylindrical shell within which are vertically spaced horizontal partitions 12 having a core of narrow tubes 13 through which the cooling fluid, commonly air, can flow. The tubes 13 are of expanded polygonal cross-section at their ends only, to present a closed front, the oil to be cooled passing round these tubes inside the shell, which also contains vertical tubes 17 connecting the entrance chamber in the manifold 14 to the chamber 18. Oil to be cooled enters at the port 15 into the chamber 41, passes through ports 47 and 34 into the channel 33, and so flows via tubes 17 to pass through the aperture 20 from chamber 18 into the core formed round the tubes 13, travelling in zig-zag path round opposite ends of alternate baffles 12, eventually to pass through ports 36 and 49 to the exit 16. To protect the core from high pressures which may be set up in the apparatus when the oil has congealed, valves 57 and 51 are included, which will be closed when oil in the entrance and exit chambers 41 and 42 respectively is above a certain pressure. The valve 57 can be opened and simultaneously the valve 56, which is carried along with it, can be moved towards a closed position, by the expansion of a thermally sensitive substance 66 pressing against the fixed shaft 62, the reaction forcing the sleeve 61 and the attached valve assembly to the right. Similarly the thermally sensitive substance 74 can close the valve 58 at a predetermined temperature. When the oil is cold, valve 57 is closed and valve 56 is open to bye-pass the oil directly to the outlet. As the oil warms up valve 57 opens and valve 56 remains open so that some oil passes to the channel 33 from where it can either pass through the core or via port 35 and port 48 to the outlet, whilst some is bye-passed directly to the outlet as before. At a still higher temperature valve 56 closes and all oil passes through port 47, whilst finally at the operating temperature, valve 58 closes, and all oil must pass through the cooler proper. If a high pressure is set up at the inlet, valve 56 can pass right through port 46 to allow oil to bye-pass the core to avoid damaging it, and similarly valve 58 will open if a high pressure exists in chamber 45. For decongealing purposes warm oil can be introduced at various points into the core, whilst the device is applicable to jacketed coolers.
