Abstract: This concerns a toilet seat provided with a ventilation system, fitting into the conventional shape of any toilet seat, composed of two superimposed parts, connected by a hinge permitting articulation of the two parts, one (1) of which lies directly on the bowl of the WC, and having in its rear part a location (2) in order to house therein a small electric motor (3) powered by single electric batteries (5). It is also composed of an air filter (4), a central cavity, a transverse pipe with lateral outlets (12, 13), on two sides of the toilet seat, at the inlet of which are placed pellets of a deodorising product (16, 17) which impregnate the air while the toilet seat is being used. In the rounded part located at the front of the toilet seat is a lower side hole forming a suction vent (6) intended for unpleasant odours which are thus sucked up and directed towards the filter by virtue of the lateral pipes, while venting air scented with the deodorising product propagates into the atmosphere. <IMAGE>

Abstract: The shaft line includes a joint (5) before the propeller shaft (25) whereby the angularity of the latter is enabled with respect to the driving shaft (23). Besides the standard universal joints to be applied, a series of special gearbox and hydraulic joints have also been developed for the installation proposed. All of a multitude of propeller-shaft carriers (331) consist of the turning assembly (331T) and stationary assembly (331S) whose connecting and thus pivoting vertical axis coincides with the angularity axis V of the joint. 
     Whereas the existing systems of ship steering with the rudder propeller (Schottel, etc.) have the shaft line "broken" several times in the elevation plan, the proposed installation is a "direct drive" with complete shafting lying in a horizontal line which makes the installation generally simpler, more reliable and capable of transmitting greater power ratings. 
     In a series of cases the installation is a capsuled reducing-steering-propelling "compact" to be simply attached to or inserted into the ship's stern even while the ship is afloat.

Abstract: A position actuator includes a motor driven low efficiency lead screw (8) with a follower (23) moving in parallel relation to a valve coupler (9) of a valve shaft and a switch operator (62) of a force/torque limit (10) unit. A lever (15) is pivotally coupled to the follower (23), coupler (9) and the operator (62). The lever pivots (15) about the operator (62) to move the valve coupler (9) at a valve limit. The coupler (9) cannot move and the lever pivots (15) about the coupler (9) to move the operator (62) and actuates a switch to signal an alarm and/or another controller. The limit unit includes an elongated coil spring (54) having a low spring rate within a tubular housing (49) having mounting plates (50) for switches. The operator (62) passes through the spring (54) and has retainers abutting the spring ends and the housing (49) to provide a factory spring calibration. The lever couplings (34) include a lever opening with spaced knife-edges (31,32) to provide low friction engagement. In a damper control, limit unit is mounted to a driven sector gear (98) and a lever (104) is secured to a damper shaft (91). At limit condition, the shaft (91) cannot move and sector gear (98) movement moves the operator (102) to actuate the switch. A linear actuator (112) may be connected directly to the operator for in-line movement. The limit unit (10) provides precise identification of the actuator movement (112) and may provide end limit signals for initializing a stepper motor (7) control (118) and/or a constant speed motor control.

Abstract: Method and apparatus for metering polyphase power sources in which cycles for each phase are sampled at each degree and converted to a binary representation of amplitude. Sampling commences with a zero cross-over and a first digital conversion provides range data for developing scaling factors which are retained in memory and for providing a selective gain for amplifying the same sampled degree and obtaining a second, range digital conversion. The scaling factor and the range data then are multiplied to develop a digital representation of the sample amplitude which may have as many as 21 significant bits plus a sign bit. These expanded data valuations for current and voltage then are selectively multiplied for each degree sampled to developed data available for generation of 12 electrical parameter outputs. Generally, six of these outputs will be elected by the user. Volt amperes are computed with respect to the zero cross-over events for both voltage and current samples, while quantities such as Q and var are developed by selective delayed multiplication of the unit degree samples.

IPC: G10L25/93

Abstract: Apparatus for detecting a fundamental frequency in speech in a changing speech environment by using adaptive statistical techniques. A statistical voice detector (103) detects changes in the voice environment by classifiers that define certain attributes of the speech to recalculate weights that are used to combine the classifiers in making the unvoiced/voiced decision that specifies whether the speech has a fundamental frequency or not. The detector is responsive to classifiers to first calculate the average of the classifiers (202) and then to determine the overall probability that any frame will be unvoiced. In addition, the detector using a statistical calculator (203) forms two vectors, one vector represents the statistical average of values that an unvoiced frame's classifiers would have and the other vector represents the statistical average of the values of the classifiers for a voiced frame. These latter calculations are performed utilizing not only the average value of the classifiers and present classifiers but also a vector defining the weights that are utilized to determine whether a frame is unvoiced or not plus a threshold value. A weights calculator (204) is responsive to the information generated in the statistical calculations to generate a new set of values for the weights vector and the threshold value which are utilized by the statistical calculator during the next frame. An unvoiced/voiced determinator (205) then is reponsive to the two statistical average vectors and the weights vector to make the unvoiced/voiced decision.

Abstract: In the rate-of-rotation sensor arrangement with fibreoptical Sagnac interferometers for three spatial directions and common read-out optics, three fibre sensor coils (81, 82, 83) for the three spatial axes are fed by a beam divider structure (3 to 7) of a total of five beam dividers with monomode lights circulating in opposite directions in the fibrecoils. The modulators (91, 92, 93) in each case allocated to one sensor coil are operated at different frequencies so that an electronic separation of the three rate-of-rotation signals, which can be read out via a detector (11), becomes possible with conventional signal evaluation methods in the electronic signal processing. Only one common mode filter (2), one light source (1) and only one detector (11) is needed for the three gyro axes. Assuming that the reliability of a fibre gyro is essentially determined by the possible failure rate of the light source (1), the probability of the failure of the total system is three times less than in the case of three light sources as are required in the previously used rate-of-rotation sensor arrangements with individual structures. The technical complexity and the production costs become distinctly lower. <IMAGE>
