Filed: 1918-11-29
Abstract: 124,167. Caterpillar Tractors, Ltd., (Holt Manufacturing Co.). Nov. 29, 1918. Relay or power apparatus.-Relates to poweractuated differential epicyclic steering-mechanism for simultaneously varying the speed of motorvehicle driving-wheels and particularly adapted for endless-track vehicles. The engine shaft 11 drives a countershaft 12 through chance-speed and reversing gearing 18 of usual construction. A bevel pinion 21 on the countershaft drives a bevel wheel 22 on a live axle 23 carrying at each side a driving sun-wheel 31 and a freely-mounted carrier 28 carrying planet-wheels 29 meshing with the sun-wheel and with an internal gear 30 on a drum 32 mounted on the axle and having at its outer end a driving-pinion 33 suitably geared to the vehicle driving-wheel or endlesstrack driving-sprocket. The planetary carriers are normally non-rotary, but for steering the vehicle they are simultaneously and equally rotated in opposite directions so as to accelerate the speed of one driving-wheel and decelerate the other, and thus cause the vehicle to turn to the right or left. This is effected by throwing into gear the appropriate clutch 38 or 39 and so causing the rotation of the engine shaft 11 to be transmitted through the clutch, bevel gear 40, 42 and bevel-wheel 35 to two bevel-wheels 34 fixed on the planetary carriers, thus rotating the carriers in opposite directions and varying the speed of the driving-wheels.

Title: Improvements in and relating to electron discharge apparatus
IPC: H01J9/385
Filed: 1920-07-09
Abstract: 147,822. British Thomson - Houston Co., (Assignees of Langmuir, 1.). Oct. 16, 1913, [Convention date]. Void [Published under Sect. 91 of the Act]. Vacuum tubes.-In a process for removing ionizable gas, the anode is subjected to prolonged electron bombardment, preferably without appreciably heating it, the gas disengaged thereby from the anode being removed from the tube. For this purpose a voltage is applied between a filament cathode heated to incandescence and the anode of a value insufficient to produce a blue glow, the voltage being raised as the gas is removed; the final voltage is preferably higher than the working voltage unless this is very large, say 50,000 volts. Anodes so treated may be removed from the tube without re-absorbing gas. The anodes may consist either of tungsten or like filaments 12, Fig. 1, loosely. strung on hooks or forked frames 15, or of disks mounted on stems. The cathode is in the form of a straight or U-shaped filament held taut in a glass, quartz, or metal frame 9 by a spring. The grid consists of a wire 10 wound around the frame 9. A negative charge on the grid decreases, and a positive charge increases, the current between the electrodes. Exhaustion may be effected by a Gaede pump; chemical absorbents, such as electrically vaporized calcium or magnesium, may also be used. During exhaustion, the tube is strongly heated, and the anode may be brought to incandescence by the passage of current. The anodes, when of disk form, may be heated to redness by electrical bombardment. The residual gas pressure may be a few hundredths of a micron; it must be lower when the electrodes are widely separated than when they are close together. The valve may be used as a rectifier in receiving systems for wireless telegraphy. In the arrangement shown in Fig. 5 for use as a generator of continuous oscillations, the anode-filament circuit includes a battery 40 and an inductance 41 coupled with an inductance 43, which is connected in parallel with a variable condenser 44 between the grid g and the filament c; the coupling between the inductances 41, 43 may be variable. A transformer winding 45 is coupled with the inductance 41.

Title: Improvements in and relating to electrical apparatus for comparing impulse frequences
IPC: G08C19/26
Filed: 1937-07-26
Abstract: 499,601. Measuring frequency. BRITISH THOMSON-HOUSTON CO., Ltd. July 26, 1937, No. 20639. Convention date, July 24, 1936. [Class 37] . [Also in Groups XXXV and XL] A difference in the relative frequency of two series of impulses is arranged to charge a condenser to alternative polarities in accordance with the sense of the difference. As shown the two sources of impulses 1, 2, energize the input circuits of valves 3, 4 respectively and output circuits of these are each arranged to energize in opposite phases valves 9, 11 and 9<1>, 11<1>. A condenser 16 is charged at each energization of the valves 11, 11<1> from condensers 15, 15<1> respectively which are charged to opposite polarities by the preceding impulse from the valves 9, 9<1>. Thus when the frequencies are equal no charge builds up on the condenser 16 but when unequal this becomes charged to a polarity determined by the source with the greater frequency. Two relays 20, 21 may respectively be arranged in the two output circuits of a valve 18 so that they are selectively energized according to the polarity of the condenser 16 with which the input circuits are associated. These relays may control a reversible motor 24. The system may be used for indicating or controlling the frequency difference. For example the two impulses may be produced by threads in a fabric passing through a machine and acting upon two photo-electric means in accordance with skew in the fabric, the skew being corrected by the operation of the motor as described in Specification 499,753, [Group XL].

Title: Speech recognition system
IPC: G10L25/87
Filed: 1977-05-17
Abstract: In a speech recognition system of the type including a recognition unit responsive to a voice input and a conditioning input for recognizing the voice input to produce a recognition output, a start signal is produced whenever a voice input exceeds a threshold level and a pause interval detection signal is produced whenever a voice input falls below a threshold level. An output timing signal is produced when the detection signal lasts a preselected interval of time that may be either about 250 milliseconds or about 250 milliseconds plus a delay. The recognition output from the recognition unit produced in response to the detection signal is displayed in response also to the detection signal. The result is delivered to a utilization device in response to the output timing signal. The delay may be given either by a predetermined duration or an interval between those instants at which the above-mentioned 250 milliseconds have just elapsed after production of the detection signal and after production of another pause interval detection signal for a next following voice input. During the delay, it is possible either by a manually operable switch or a cancel voice input to cancel delivery of the recognition result displayed to be incorrect.

Abstract: 338,217. Johnson, J. Y., (I. G. Farbenindustrie Akt.-Ges.). July 6, 1929. Halogenated anthraquinone-2-1-benzacridones. -4.Bz2.3.4.5-Pentahalogenanthraquinone - 2.1 - benzacridones are prepared by condensing 1.4-dihalogenanthraquinone-2-carboxylic acids or their esters with tetrahalogenanilines having a free oposition to the amino group, acridone ring closure then being effected according to known, methods. Or the same bodies may be obtained by treating anthraquinone-2-1-benzacridones containing halogen at least in the Bz2- and Bz4- positions with halogenating agents in the presence of an organic solvent. When starting from products having the 4- position free only chlorinating agents are to be employed since bromine only enters this latter position in small amounts. In examples (1) 1.4-dichloranthraquinone-2-carboxylic acid benzyl' ester is condensed with 2.3.4.5-tetrachloroaniline, the product saponified and ring- closed; (2) Bz2.3.4.5-tetrachloranthraquinone-2.1. benzacridone (prepared according to Specification 338,216) is treated in nitrobenzene and in presence of iodine with sulphuryl chloride; (3) 4.Bz2.4 - trichloranthraquinone-2.1-benzacridone (prepared by condensing 1.4-dichloranthraquinone-2-carboxylic acid with 3.5-dichloraniline and ring-closure of the product) and Bz2.4-dichloranthraquinone-2.1-benzacridone (prepared according to Specification 338,216) are chlorinated as in (2).
