Title: Apparatus for speech pattern derivation
IPC: G10L21/06
Filed: 1975-01-24
Abstract: 1533112 Speech pattern derivation LARYNGOGRAPH Ltd 8 Jan 1976 [24 Jan 1975]  3269/75 Heading G1N(E) [Also in Division G5] In a laryngograph for monitoring the vocal fold vibrations in a speaker's larynx in speech training &c., a single frequency oscillator, Fig. 2, or a broad band oscillator, Fig. 3, supplies a carrier wave to a transmitting aerial positioned adjacent the larynx. The modulated carrier wave is picked up by a filter further adjacent aerial whose output is detected 3, Fig. 2, or demodulated 8, Fig. 3. The result is filtered 6 to produce a vocal fold waveform Lx representative of the "voiced" sounds in each utterance. The carrier wave level is maintained constant by two alternative types of feedback system controlling the oscillator 2 or the detection circuits (which may employ slicing techniques). The electrode aerials may take the form of a standard printed circuit board which is etched to produce a circular element with a concentric ring spaced therefrom. Larynx waveform L X  displays and vocal fold vibration determination. The signal from the filter amplifier 6 is fed via a band pass filter 40, Fig. 4, which supplies an amplitude sensing circuit 51  connected to a memory input control 52. The control 52 controls the input pulses, from a clock 50, which are gated 48 under the control of a closure pulse generator 42, supplied, as shown, by an infinite clipping circuit, to provide a uniform pulse for each larynx closure. This enables pulses to be counted 49 to give a measure of the vocal fold vibration period Tx which is eventually stored in a main memory 54. The pulses from the counter 49 are directed by the control 52 into a random access memory 54 connected to a display unit 57. The signals reaching the display must be logarithmically converted at 56, or at any other convenient point in the system. Alternatively, suitable non- linear clock pulses may be used. A chart recorder 45 or a "X-Y" plotter may feed the memory via a buffer memory so that only voiced segments of the speech are drawn slowly, while intervening voiceless pauses are moved over quickly. In a further embodiment, Figs. 6 and 7 (not shown), the characteristic frequency in two frequency bands F 1 , F n  are shown on a stored display with a colour distinction between parts of an utterance which are voiced, fricative (consonants) or voiced fricative in form.

Title: Improvements in or relating to a retractable clamping device
IPC: B64D1/10
Filed: 1960-02-01
Abstract: 916,264. Dropping from aircraft. SIREN. Feb. 1, 1960 [Jan. 31, 1959], No. 3478/60. Class 9 (2). [Also in Groups XXV and XXXIII] Means for dropping loads from aircraft comprises a clamping device adapted to hold against a runway mounted on the floor of the aircraft, a support means A movable along the runway, the device having a clamping element 12 which is capable of exerting a clamping force on the support means A in a given direction and which is carried by an arm 11 mounted on a support 7 for pivotal movement from an operative clamping position to an inoperative retracted position about an axis W which is oblique relative to the given direction, the obliqueness being in such direction that the pivoting of the arm from the clamping position to the retracted position automatically causes the clamping element to move away from and release the support means. As shown, the clamping element is a screw which is threaded into the arm 11. The arm 11 is biased by means of a spring 16 to the position in which the clamping element is released from the support means A, the movement in this direction being limited by the abutment of the arm against a lug 15a on the support 7. The position of the arm when clamped is determined by the abutment of a lug 15 carried by the arm against the support. The support 7 is adjustably fixed to a stand 1 by means of two rods 8, each of which extend through aligned apertures 5 in the stand and a transverse aperture in the support 7. A plurality of the clamping devices are used to secure the support means to the runway and one application is in an aeroplane in which the support means is to be parachuted to the ground. The support means is normally held by an abutment to the runway, the clamping devices preventing movement perpendicular to the runway; when the abutment is withdrawn a pull applied to the support means by a parachute, which causes it to move longitudinally of the runway, moves the arm 11 of each clamping device about its pivot and as soon as the clamping force of the element 12 against the support means is sufficiently reduced the spring 16 pivots the arm quickly to its retracted position.

Title: Wheel constant slip brake control device particularly for aircraft
IPC: B60T8/17
Filed: 1955-02-08
Abstract: 764,776. Anti-skid aircraft brakes. GOODYEAR TIRE & RUBBER CO. Feb. 8, 1955 [Aug. 13, 1954], No. 3677/55. Class 103 (1). The slip of an aircraft wheel is controlled by means of a circuit in which the outputs from two similar generators 5 and 6, the former on an unbraked wheel 2 such as the nose wheel, and the latter on a braked wheel 3, are combined to operate two relays 9 and 15. The operating coil 10 of relay 9 is caused to open contacts 11, 12, so long as the braked wheel 3 is rotating above about 15 miles per hour. If the brakedwheels speed is lower than this, the contacts 11, 12 will be closed and a signal lamp 14 will be energized to show that the automatic control apparatus is inoperative. Provided the braked wheel 3 is rotating above about 15 miles per hour and there is a difference between the speeds of rotation of wheels 2 and 3 equivalent to or greater than about 10 miles per hour, coil 16 of relay 15 will be energized to close contacts 17, 18 and operate coil 19 to open solenoid valve 20 to reduce the pressure in the brake line 22 as necessary to preserve the slip speed constant at about 10 miles per hour which it has been found gives a maximum coefficient of friction.

Filed: 1927-02-14
Abstract: 266,002. Bruhn, F. W. G. Feb. 15, 1926, [Convention date]. Periodic-counter speed indicators.-Relates to speedometers of the type in which a member controlling the indicating hand is driven forward periodically against the action of a spring, the periods of the impulses being determined by escapement mechanism. A shaft 2 driven at a speed proportional to that to be measured, carries a gear 3 which winds up the spring motor 11 which drives the controlling shaft 10. The speed of the shaft 10 is kept constant by an escapement 15 and a balance wheel 17. A cam 9 on the shaft 10 causes a forked lever 7 to actuate a clutch member 6 intermittently, and so causes a pinion 8 to be rotated periodically by the shaft 2 for a definite interval of time. The pinion drives a gear 20, which is restrained by a spring 21, and a pin 23 on the gear engages a pin 23<1> on a wheel 24 and sets it against the action-of a spring 25. A pin on the wheel 24 engages a pin 26 on a wheel 27 connected with the indicating hand 30 by gears 28, 29, and restrained by a spring 31. The wheels 24, 27 are formed with ratchet teeth which are engaged by pawls 36, 37 controlled by cams 38, 39 on the time shaft 10. In operation, the pawl lock on the wheel 24 is released to allow backward movement while the wheel 20 is being driven, and the pawl lock on the wheel 27 is similarly released as soon as the wheel 24 has taken up its new position. With recording apparatus.-A pinion 32 on the spindle of the hand 30 actuates a rack 33 on which is mounted a marker 34 co-operating with a record chart.
