Title: Speech processors
IPC: G10L25/00
Filed: 1972-01-27
Abstract: 1369711 Speech processor WESTERN ELECTRIC CO 27 Jan 1972 [3 Dec 1971] 3828/72 Heading H4R In a speech processor, an unwanted speech signal is suppressed from a wanted speech signal, by sampling the former signal during a substantial portion of a pitch period so as to calculate a delay parameter and an amplitude parameter therefrom, applying the composite wanted and unwanted signal to a summing means via a direct and an indirect path, and controlling the delay and the gain of the indirect path with the aid of the parameters. The parameters in effect predict the future value of a speech sample in dependence on its current value and they may be calculated in the manner described in Specification 1,266,929. In Fig. 1, acoustic reaction between loudspeaker 1 and microphone 2 is suppressed by processor 8 which samples (18) an incoming signal at a 6 KHz rate so as to obtain between 30 and 60 samples during any one pitch period and then extracts the delay and gain parameters (14). These are supplied, after a delay 19A representing the transit delay in the air space between 1 and 2, to a predictive filter 9. The latter, Fig. 3, contains two parallel paths connected between the output of a 6 KHz sampler, supplied with the combined desired and undesired signals from the microphone 2, and a subtractor 10. One of the paths includes a delay network 12 and an amplifier 13 whose delay and gain are controlled by the parameters so as to adjust the value of the signal therein, i.e. to predict the value of a subsequently arriving signal c in dependence on the current value of c. The effect on the signal a is allegedly such that by subtracting the output of the predictor 11 from the signal on the direct path, only the signal c is cancelled and the wanted signal a proceeds to the digital/analogue converter 10A for subsequent transmission.  A centre-clipping echo suppressor, viz. one in which the speech band is divided by filters into a plurality of sub-bands each of which has its centre frequency clipped in accordance with the energy content of the band as in Specification 1,343,656, may be provided at both ends of a transmission channel so as to eliminate near and far end echo, the control of the suppressor being effected by the parameters of delay circuit 19A (Figs. 7 and 8, not shown).  In another arrangement for suppressing signals from an unwanted source, an (or more) additional microphone is located such that it is equidistant with the main microphone from the source. The outputs of the microphones are processed so as to derive delay and amplitude parameters which are then applied as discussed above to a predictive filter in the output of the main microphone (Figs. 9 and 10, not shown).

Title: Improvements in band or winch brakes
IPC: B66D5/00
Filed: 1960-02-03
Abstract: 868,193. Drum brakes. HOLMES & CO. Ltd., CHARLES, D., and GRAY, G. H. Feb. 3, 1960, No. 3848/60. Class 103 (1). A winch brake comprises an annulus made of two semi-circular elements 2<SP>1</SP> and 2<SP>2</SP>, fast with a semi-circular element 2<SP>3</SP> forming a U-section. The element 2<SP>1</SP> carries two spring-retracted sigmental brake shoes 5<SP>1</SP> and 6<SP>1</SP>, which are applied to the drum by rotation of a rod 18, which causes cam members 10 and 11 to be rocked about their pivot pins 12 and 13 so that their nose portions 101 and 11<SP>1</SP> displace the brakes against the effect of retraction springs 8 and 9 so as to bear against the drum. At the same time, the reaction of the annulus reverses the same so that the semi-circular brake lining 4 is also brought to bear on the brake drums and retardation pressure is applied inwardly over almost the entire periphery of the brake drum. On reverse rotation of the operating rod 18, the cam members 10 and 11 are moved back to the initial position and the retraction springs 8 and 9 pull back the shoes 5 and 6.

Title: Apparatus for Handling Liquid Cargo.
IPC: B63B22/02
Filed: 1967-01-26
Abstract: 1,157,532. Transferring liquid cargoes. FMC CORP. 26 Jan., 1967 [25 Feb., 1966], No. 3858/67. Heading B8E. Apparatus for transferring liquid cargoes to and from a vessel S moored offshore comprises a circular anchor base 12 on the seabed 18 having a riser pipe connecting a shore connected product line 16 to an articulated cargo handling pipe system 10. A lower horizontal conduit 24 is supported by rollers 22 on a circular track on the base 12 for pivotal movement while the conduit 34 has swivel joint connection to the conduit 24 to allow universal movement relative to it. A loading mast 44 pivoted to the conduit 34 has a main permanent buoyancy tank 58 and a regulating tank 62. An offset counterweight 50 biases the mast 44 to incline away from the conduit 34 as shown. In a rest position the tank 62 is flooded and the mast 44 lies on the sea bed. When a vessel S moors compressed air is introduced into an air line 64 to force water out of a port 70 so that the mast rises to the position shown. A line 92 to the vessel's hoist now raises the mast until the adapter 88 can be connected to the ship's manifold and the mast can be secured in position by lines 96 passed to bollards 98. In ship loading position the port 70 will be exposed draining the tank 62 completely but as loading progresses it will enter the water and partial flooding will occur. On completion of loading the adapter 88 is uncoupled and a valve 66 opened to flood the tank 62 after the lines 96 have been cast off. If the lines 96 are too tight to cast off compressed air may be used to raise the mast 44 to slacken them. The articulation of the pipes allows limited movement of the vessel at its moorings.

Title: Storage of Energy Due to an Explosion.
Inventor: CONSTANTINESCO GEORGE
IPC: F41F1/00
Filed: 1917-03-23
Abstract: 128,595. Constantinesco, G., and Middleton, J. R. March 23, 1917. Ordnance, hydraulic; design; chambers.-Consists in storing the energy of an explosive by firing it behind a piston which is arranged to compress a liquid, the pressure and expansion of which are then utilized to produce motion. The invention is specially applicable to guns firing heavy projectiles, but may also be applied to hydraulic machines such as starters for engines. In Fig. 1, the invention is shown applied to a bombthrower comprising a cylinder a containing water or other liquid, provided at the front with a piston d carrying the bomb and at the rear with a piston b, behind which the explosion chamber c and breech mechanism are arranged. The forward movement of the piston caused by the explosion of the charge g compresses the liquid in the cylinder a, the liquid then driving the piston d forwards to project the bomb. A vent uncovered by the piston b allows the gases to escape, and a shear pin e prevents premature movement of the piston d. In a modification, Fig. 3, two cylinders 1, 2 are connected to a single compression chamber 3. The bombs rest in cups 9 and on rails 10. Fig. 8 shows the invention applied to a motor-starter. The explosion of the charge 14 acting on the piston 15 compresses liquid into the chamber 17 through a non-return valve 16. The compressed liquid actuates a ratchet motor comprising a piston 18 carrying a pawl 20 engaging a ratchet-wheel 21. Instead of being utilized immediately, the compressed liquid may be stored in bottles. Specification 784/97 is referred to.

Title: Electronic time cycled respirator
Inventor: PERRY KENNETH ROY
IPC: A61M16/00
Filed: 1959-02-06
Abstract: 914,343. Respiratory apparatus. PYE Ltd. Feb. 4, 1960 [Feb. 6, 1959], No. 4296/59. Class 81 (2). A respirator in which the duration of expiration and inspiration is controlled by an electronic timing circuit includes an over-riding trigger device controlling the timing circuit to cause the respirator to change its respiratory phase if the patient makes an attempt at voluntary respiration. Respiratory gas is supplied continuously through a change-over valve 2 to an inspiratory bellows 1 and thence through an inspiratory control valve 4 to a face mask 5. Expired air is drawn into an expiratory bellows 7 by way of an expiratory control valve 6. The inspiratory and expiratory valves each comprise a poppet valve 4a, 6a and a non-return valve 4b, 6b. The poppet valves are both connected to the armature 9 of a solenoid 10 which is energized by an electronic timing circuit, e.g. a multivibrator, to open the expiratory valve during the expiratory part of the respiratory cycle. The solenoid is de-energized under the control of the timing circuit or when the timing circuit is out of use to permit the opening of the inspiratory valve by a spring 12. The expiratory and inspiratory bellows are connected between a fixed plate 29 and a plate 13 which is pivotally connected by arms 14, 15 to the chassis of the apparatus. Inflation of the inspiratory bellows causes the expiratory bellows to expand, thus creating a negative pressure which induces exhalation. The negative pressure is controlled by a variable orifice 27. In the event that the patient inspires during the expiratory part of the respiratory cycle, an adjustable trigger mechanism comprising a pressure-sensitive diaphragm 24 and a microswitch 25 operates to switch the respiratory cycle to the inspiratory part. If desired, the change-over valve may be operated so that the gas supply by-passes the inspiratory bellows and the inspiratory valve and a manual control bag 22 may be inserted between the mask and the expiratory valve. Specification 914,342 is referred to.

Title: Method of recording sound by means of a ray of electrons
IPC: G11B7/00
Filed: 1932-02-15
Abstract: 389,256. Cathode-ray tubes. HARTEL, H. VON, 35A, Berliner Strasse, Zehlendorf, Berlin. Feb. 15, 1932, No. 4421. [Class 39 (i).] Sound is recorded optically by producing a luminous area in the shape of a slit of narrow width on the fluorescent screen of an electron discharge lamp. The cathode 2 of an electron discharge lamp 1, Fig. 1, is surrounded by a cylindrical-shaped control grid 3 which is covered by a plate 4 having an opening 5 therein corresponding in shape to that of the luminous area which is to be produced. The anode 6 also has an opening 7 therein of the same shape as the opening 5. This arrangement permits the beam of electrons 9 to produce on a fluorescent screen 8 a luminous area 10 in the shape of a slit of narrow width. To avoid a blurring effect in the recording, two quartz layers 11, 14 with an interposed silver layer 12 are disposed between the fluorescent screen 8 and the film record carrier 15. The silver layer 12 has an opening 13 therein the total width of which is very small, e.g. 20 Á, and the thickness of the quartz layer 14 is not greater than this amount'in order that a sound record may be obtained on the film 15 without the use of a converging lens system. Means that are light absorbing, but pervious to an electron beam, such as a plate of molybdenum, may be inserted in the path of the beam to prevent light from the filament reaching the film. To enable the strength of the electron emission to be adjusted, the control cylinder 3 may be made movable by mounting it on guide rails inside the lamp. A diagram is given which illustrates the method employed to determine the most suitable mean grid voltage to be applied.
