Abstract: The present invention is directed to a hydraulic accumulator device which may be built at low cost and which includes an elastomeric bladder member and a button or valve component adapted to seat on the oil port when pressures in the gas chamber exceed the pressure in the hydraulic line and to unseat when the pressure conditions are reversed. The device includes a button carried by the bladder positioned to seat on the oil port and is characterized by the button, bladder, and oil port having certain critical dimensional inter-relationships which greatly reduce the possibility of damage to the bladder and consequent failure of the accumulator.

Abstract: An air-powered sander is made up of a housing with a compressed air motor within it and designed for driving a sanding pad. The sander has a system for clearing dust, produced on sanding, from the pad. This system is made up of an impellor wheel freely turning on a motor shaft in the housing. On the two sides of the impellor wheel two groups of blades are present. A nozzle, joined with the airway for supplying the motor with compressed air, is used for directing at least one air jet against one group of the blades on the wheel. The other group of blades, on the other side of the wheel, is designed for producing a dust/air current for clearing sanding dust from the pad. For this purpose a dust take-up space is present extending from the pad to a position near inner ends of the second group of blades on the impellor wheel. There is furthermore a dust output airway extending from outer ends of the blades of the second group to a point at which the dust is forced out of the housing by way of an air current as produced by the impellor wheel.

Abstract: An echo canceller with improved near-end speech detection consists of a transversal filter (12) which synthesizes from an input signal (x(k)) on a receive signal path (12) an estimate of an echo replica signal (@(k)). A combiner (20) subtracts the echo replica estimate signal from the actual return echo signal (y(k)) on transmit signal path (14) to generate a first echo cancelled signal e(k). The improved near-end speech detector (24) comprises a combiner (28) and a transversal filter (26) which operate to generate a second echo cancelled signal (ed(k)) which is employed by a near-end speech detector (22) which compares the echo cancelled signal to past and present values of the input signal x(k) to ascertain the presence of near-end speech and inhibit the echo canceller. <IMAGE>

Abstract: A burner for air heaters comprises a first wall structure defining an ignition chamber with an ultrasonic atomizer discharging into the ignition chamber and with means for delivering primary air into the ignition chamber for ignition by suitable ignition device to form an igniting gas mixture. The construction includes a second wall arrangement which is adjacent the ignition chamber and which defines a primary combustion chamber which has a passage for the ignited gas mixture from the ignition chamber and also for secondary air so as to complete the combustion in the main combustion chamber. The main combustion chamber in turn is connected downstream and into an exhaust diffuser in which the completely burnt gases are delivered to a place of use for heating an area such as a space in a motor vehicle. In one construction, the combustion chamber is defined within a perforated tube which has a perforated bottom or rear wall facing an ignition chamber which is defined with an outer tube which is also perforated to provide for the inflow of the primary air. The ignition device is mounted in the outer tube adjacent the atomizer so as to ignite the fuel with the primary air and direct this ignited mixture into perforations of the main combustion chamber for continued burning therein. In another embodiment the primary chamber is defined by a perforated wall which defines an area within the outer perforated housing which comprises the ignition chamber having the atomizer in an igniting element. This ignition chamber communicates through perforations in the surrounding wall with an inlet for the primary air and one or more inlets for the secondary air in the remaining space within the outer housing which defines the main combustion chamber.

Abstract: A reaction chamber with a fluidized bed encloses two superposed cyclone separators connected in series. In order to prevent combustion gases from entering the lowermost separator by way of its particulate matter outlet, this is formed as a downwardly extended pipe, which is enclosed by a sleeve through which secondary air passes. The sleeve projects somewhat below the mouth of the pipe, and the issuing air causes an ejector action, which prevents gas from entering the pipe. The particulate matter return flow pipe from the upper cyclone is also extended downwards and terminates within the ejector.

Abstract: The braking force of a transmission and more especially the transmission of a motor vehicle, in which the torque converter component is used for braking by counter rotation of the turbine may be increased if the pump is not able to rotate freely during braking operation in the direction of rotation caused by the flow circuit in the circuit and is instead kept running at a preselectable speed or speed ratios between the turbine and the pump. In this respect a suitable member is preferably a torque converter with a turbine which is arranged on the radially inner part of the torque converter cross section and through which the flow is axial, its direction of rotation during traction operation being opposite to that of the pump.

Abstract: The present invention concerns a device for generating negative pressure inside a cylindrical roll mantle of a revolving roll. The roll has a roll mantle provided with through-holes, grooves or equivalent apertures and confining a suction chamber in the interior thereof, in which a negative pressure can be generated by suctioning air out of the suction chamber. A suction flow directed towards the suction chamber thereby prevails in the holes, grooves or equivalent apertures of the roll mantle. At least one rotor blower or equivalent is attached to the roll to revolve along with the roll, with an intake side of the rotor being connected to the suction chamber of the roll. The movement of rotation of the roll thereby produces rotary movement of the rotor or equivalent, which in turn generates negative pressure in the suction chamber. Thus, in the arrangement in accordance with the present invention, external equipment of negative pressure or a separate piping system is not needed.

Abstract: A noise suppression system implemented in communication system provides an improved update decision during instances of sudden increase in background noise level. The noise suppression system, inter alia, generates an update by continually monitoring the deviation of spectral energy and forcing an update based on a predetermined threshold criterion. The spectral energy deviation is determined by utilizing an element which has the past values of the power spectral components exponentially weighted. The exponential weighting is a function of the current input energy, which means the higher the input signal energy the longer the exponential window. Conversely, the lower the signal energy the shorter the exponential window. The noise suppression system also inhibits a forced update during periods of continuous, non-stationary input signals (such as "music-on-hold").
