Abstract: In a method and system for determining the variation of a speech parameter, for example the pitch, in a speech signal, values ms(i,j) and coupling vectors v(i,j) are calculated for time instants i and a number of values j of the speech parameter f i  for each time instant i by means of an optimisation algorithm. Of the values ms(m,j) associated with the last time instant i = m, the optimum (that is to say the smallest or, on the contrary, the largest) value is determined. By means of the coupling vectors, the variation of the speech parameter as a function of time can be obtained by means of back-tracking. 
     In the calculation of the values ms(i,j), inter alia; a cost parameter k is taken into account which is a measure of the deviation of the speech parameter f j (i) at the time instant i with respect to a predicted value for the speech parameter at that time instant i.

Abstract: An earch drilling machine includes a crown block assembly (14′), a travelling block assembly (18′) and a drawworks (20). The drawworks includes a drum (22) which rotates about a drum axis (24). The drum axis is oriented at right angles to a fast line plane defined by a fast line sheave (FL) included in the crown block assembly. In this way, the fleet angle between the drum and the fast line sheave is kept substantially equal to zero. Various sheave arrangements are described which combine proper selection of sheave pitch diameter, sheave axis angle, and sheave placement to ensure that the fleet angle of all of the sections of line extending between the crown block assembly and the travelling block assembly are reeved with a fleet angle exactly equal to zero. In this way line wear is reduced and the height, weight and windage of the mast are all minimised.

Date May 18, 1989.A glazing profile strip (1) which has a foot (9) with a toothing (10) for anchoring the strip (1) on a spacer (2) connected to the structure (4) of the building, has a slot (11) in that foot (9). This slot initiates at the outside (12) of the two sealing lips (6) protruding from the foot (9) and first forms a though-like enlargement (13). This enlargement serves for receiving a filler profile strip (17) that is connected to the sealing lips (6) only by thin bridges (18). The slot then continues below that enlargement by forming a narrow portion (14) having a flared mouth (141) and terminates in a larger groove (15). The narrow portion (14) is formed by two ribs opposed to each other which have a lower side (25) formed as an undercut. That side (25) serves as a rest for a head of a replacement filler profile strip which is inserted into the slot. Prior to this insertion, the present filler profile strip (17) is removed by separating its thin bridges (18) from the walls of the enlargement. The lower side (25) of the narrow portion secures the head of the replacement profile strip and with it the strip itself against being pulled out of the slot. Thanks to the possibility of replacing the filler profile strip (17) by another one of different design, different dimensions and different aspect the glazing profile strip can be used for different requirements without altering its basic concept.

Abstract: The invention relates to a process for the cleaning of flue gas from an incineration plant for coal, domestic waste and special wastes. The problem associated with such incineration plants is that the solids precipitated from the flue gases contain both heavy metals and also dioxins and furans. These precipitated solids must therefore be stored in special landfills or otherwise further processed. On account of the substantial quantities of the solids arising, both solutions are unsatisfactory. To solve this task the invention envisages that the majority of the solids carried in the flue gas are removed by dry dust filtration and the remaining solids are removed by subsequent acidic flue gas scrubbing. The solids from the dry dust filtration are melted down, and the settled solids from the flue gas scrubbing water are leached out and filtered. By this means the result is achieved that the majority of the solids is present in a form usable as building material, and only a small part of the solids must be either stored in landfill or further processed. The invention is applicable to incineration plants for coal, domestic waste and special wastes. <IMAGE>

Abstract: Arranged in the power train of a motor vehicle as an all-wheel drive locking system is a planetary gear mechanism, on the planet carriers of which a braking device acts. The planetary gear mechanism comprises an input sun gear, an output sun gear mounted coaxially next to the latter, and the planet gears simultaneously meshing with the two sun gears. In order to keep the frictional losses low and avoid self-locking in the planetary gear mechanism, the normal module of all the gears is as small as possible and proportional to the driving torque to be transmitted and the operating pressure angle is as large as possible.

Abstract: A beam (110) of coherent light is coupled into an array of light detectors (146, 148, 150, 152) using a beam splitter (120) for dividing the beam into a probe beam (102) and a pump beam (122) and a spatial light modulator (144) for varying the intensity of the probe beam (102) in a first direction perpendicular to the direction of propagation of the beam. A photorefractive element (134) is positioned to receive the modulated probe beam and the pump beam, the beams being oriented with respect to the photorefractive element (134) and with respect to each other such that photorefractive two-wave mixing within the photorefractive element (134) nonreciprocally transfers energy from the pump beam (122) to the modulated probe beam, which is then detected by the detector array (146, 148, 150, 152). A first lens system (138, 140) may be positioned in the path of each probe beam (102) between the beam splitter (120) and the spatial light modulator (144) for expanding each probe beam (102) in the first direction, while a second lens system (130, 132) may be positioned in the path of each pump (122) beam between the beam splitter (120) and the photorefractive element (134) for expanding each pump beam (122) in the first direction.

Abstract: Claimed and described is a working method for eliminating work interruptions caused by the tying means in tying machines, which is characterised in that the tying means located in the machine are withdrawn from the tying means coil moved counter to the feeding direction of the tying means in the event of a malfunction, or is automatically withdrawn from the machine "at the press of a button". As a result, intervention in the machine, and hence in a packaging line in which the machine is integrated, is no longer necessary. The fault can be eliminated from the outside, for instance by cutting the destroyed start of the tape and renewed introduction into the machine. A working method for preventing work interruptions caused by tying means is characterised in that, in the event of a mains interruption or an interruption in the operation of the machine exceeding a preselected time period, from the tying means coil then moved automatically counter to the feeding direction of the tying means, the tying means is at least withdrawn from the tying means store.
