Title: Improving the naturalness of speech signals
Inventor: NILSSON MATTIAS
IPC: G10L21/02
Filed: 2009-12-08
Abstract: A method, terminal and program for processing a speech signal, in which the speech signal is received over a network from a transmitting device, wherein the frequency components in the received speech signal are limited to a predetermined frequency range and the received speech signal has been filtered using a transmitter frequency response over the predetermined frequency range. The received speech signal is decoded. The decoded speech signal is filtered using a receiver frequency response which is complementary to the transmitter frequency response over the predetermined frequency range to thereby reduce distortion in the speech signal introduced over the predetermined frequency range by using said transmitter frequency response. The receiver frequency response is the inverse of the transmitter frequency response. The invention aims to improve the naturalness of speech in communication systems.

Abstract: 1,178,640. Analogue / digital converters. BROWN BOVERIE & CO. Ltd. 1 March, 1968 [3 March, 1967], No. 10204/68. Heading G4H. In an analogue/digital converter of the type in which pulses generated at a frequency dependent on the analogue input are counted in a counter 12 (Fig. 1), negative feedback is provided by a pulse shaper 6 delivering a pulse of constant width and at a reference voltage to a low pass filter 7 connected to an amplifier 1 to which the analogue input is fed. In the embodiment described in which a difference signal derived from a voltage kVref at input 17 and the analogue signal at input 16 is fed to the amplifier 1 connected to the pulse generator 4, the output of the pulse generator is fed via a gate 13 to the counter 12 which counts from, e.g. - 7000 for a measurement cycle of, e.g., 20 ms., the count at the end of each measurement cycle being displayed together with the sign. 'The pulse shaper 6 includes two bi-stable devices (19, 20, Fig. 2, not shown), the bi-stable (20) being connected via an amplifier (25) to the lowpass filter 7. Automatic correction of zero drift may precede each measurement cycle by short circuiting the analogue input and allowing the counter to count down from zero, the measurement cycle count commencing from the count reached at the end of the calibration cycle.

Abstract: 623,549. Turning-gear. BENDIX AVIATION CORPORATION. April 2, 1946, No. 10218. Convention date, April 5, 1945. [Class 7 (v)] In an engine starter drive in which a pinion member is moved into engagement with an engine member by means of a control member mounted on an operating member in such a manner that upon relative rotation the control member is moved longitudinally along the operating member a sleeve of soft elastic material, such as rubber, forms the sole driving connection between the control member and pinion member which sleeve is connected at its ends to the control and pinion members and is adapted to be compressed to cushion the shock in the case of tooth abutment between the pinion member which sleeve is connected at its moved into engagement with the engine member. As shown a nut 12 which co-operates with an externally screwed sleeve 5 held by a pin 6 to a driving shaft 1 is connected to a pinion 8 by a ring 15, soft elastic sleeve 19 (e.g. of rubber) and flange 9. The nut 12 has four radially extending lugs 14 engaging slots 16 in the ring 15 and is held in place by a snap ring 18 which is sprung into a groove 17. The sleeve is anchored at its ends respectively to the ring 15 and the flange 9 such as by bonding or cementing. An anti-drift spring 21 is held at its right-hand end by a washer 22 which bears against a shoulder 7 on the screwed sleeve 5. The washer also serves to lock the pin 6 in place. The nut 12 moves off the end of the threads on the sleeve and to ensure immediate re-engagement when power is applied to the shaft 1 a spring 25 is employed held in place by a cover 28 and snap ring 29. In a modification, Fig. 4, the pinion 37 is arranged to move towards the end of the driving shaft 31 at which the power is applied and the pinion is secured to the elastic sleeve through a ring 44 in a manner similar to that in which the nut 12 is secured to the sleeve.

IPC: D06F71/30
Abstract: 105,797. Cranage, H. B., and Fox, L. April 27, 1916. Ironing-machines with pressing action only; feeding-arrangement.-A machine for opening and pressing the seams of clothing comprises an iron raised and lowered by means of a cam on a driven shaft, and an independently driven feeding-device formed with a pointed end, so that, as it is reciprocated, it opens the seam and feeds it to the iron. In some cases the seam is opened by the nose of the iron or by a fixed part mounted in front of the feeding-device. The feeding-device may be arranged above or below the work, and the frame of the machine may be vertical or arranged horizontally on a stand &c. in the same manner as a sewing-machine. One form of machine is shown in Fig. 1, in which the work is supported on a spring-mounted head e fitted with a U-shaped feeding-frame 1 with a pointed end 1<a>, the iron x being mounted on a lever w pivoted at y between curved side members a<6> of one part a<2> of the frame a. The end of the lever w is connected by a spring 11 with the frame part a<2>, and carries a spring-mounted roller 6 engaging a cam 3 on a shaft v, fitted outside of the frame with fast and loose pulleys. The bolt 9 carrying the roller 6 is adjustable in the end of the lever w to vary the ironing pressure. The feeding-frame 1 is connected bv a link 18 with a forked arm z embracing a second cam 4 on the shaft v, the link being pressed down by an arm 22 of a lever 21 connected at the other end to the frame by a spring 23. The link 18 may be connected to the fork z by a pin adjustable in a slot so as to permit variation of the feed, and the iron may be heated by gas supplied through a pipe 17. The head e is mounted on a spring h in a hollow upright member a<1> of the frame, and is lowered bv a treadle m and rod l to permit the work to be placed in position, the feeding-frame being held up by a stop. A worktable u is fitted to the frame below the head, and the treadle m, or a separate treadle, may be connected by an arm o and rod q to the belt-shifting gear r. A modified form of feeding-device is shown in Figs. 8 and 10. The iron x is mounted and driven in the manner previously described, but the head e is hollow and contains a serrated plate 27 having side pins 29 guided in inclined slots 31 in the head. A cam 34 on a vertical shaft 42 driven from the shaft v causes' the feeding- plate 27 to rise and fall and move forward and recede, the seam being opened by the nose of the iron. To allow the head e to be raised and lowered by the treadle as before, the shaft 42 is keyed in the hub of the gear-wheel 40. An horizontal machine is shown in Fig. 14, in which a feeding-plate 50 arranged below the work is reciprocated from a forked arm z, the intermediatelink 52 being connected to a pivoted rocking arm 53 so as to cause the feeding-plate to rise and fall. In a further modification, shown in Fig. 19, the feeding is effected by a wheel 60 driven by a friction ratchet 65 from the shaft v, and the seam is opened by a pointed part 73 of a fixed cover 71.

June 30. 1916 Electric clocks.-The crutch I of a pendulum, being provided with a counterweighted pawl K<1> and a pallet K<2>, drives a ratchet-wheel L and receives an impulse from a gravity lever A, from which the pawls disengage a catch B. A supplementary catch C engages a fixed stud F to prevent the main catch from interfering with the gravity lever after disengagement. The portion of the gravity lever behind the pivot makes the circuit of an electro-magnet S, S<1> by contact with its pivoted armature R, and this armature resets the gravity lever, the main catch re-engaging when the supplementary catch is tripped by a finger on the lever. The electric contacts T, T<1> are separated by a mechanical contact V. In order to buffer the arrest of the armature, it is provided with a stiff spring R' having a pin R<3> to strike the core before the armature itself does so, adjustment being made by a screw R<2>.
