Granted: 1986-10-21
Abstract: ABSTRACT:       The invention relates to an electrodynamic transducer of the flat-diaphragm type, in which the movement of the voice coil (former) (2, 3) is trans-mitted to the diaphragm (1) via at least one auxiliary cone (20).  The auxiliary cone (20) is secured to the centring diaphragm (7) along its outer rim (10), via a coupling element (23).  This has advantages as regards the construction and the manufacturing technology. Moreover, a low-distortion transducer is obtained.  The invention also relates to a method of manufacturing a transducer in accordance with the invention.

Abstract: IMPROVED MANUFACTURE OF OPTICAL FIBERS            Abstract This invention relates to an improved method of making optical fibers utilizing a technique for minimizing taper, including entrance taper, in an optical fiber preform made by the deposition of reacted glass precursor material on the inside of a tube.  In one embodiment, a torch (or other heat source) deposition function is determined, which relates the amount of deposited material as a function of distance from the torch or other heat source.  A velocity profile for the moving heat zone can then be determined that minimizes taper.  For example, in a single mode optical fiber preform made by the modified chemical vapor deposition technique, a reduction in entrance taper in a 90 cm long preform of from about 30 cm using a linear velocity profile to about 10 cm with a profile determined according to the inventive technique is achieved.

Abstract: Abstract of the Disclosure A device for cleaning obstructions from the reject end of a centrifugal separator without               normal operati-on. Modern small-sized separators, in particular, are liable to become blocked, and the usual method of removing the blockage is to use a water jet or pressurized air which is led to the obstructed reject end by various methods. The disadvantage associated with these methods is that the im-purities removed by the jet partially contaminate the regu-lar flow. This invention will help to avoid this because cleaning is effected by means of a device comprising a chamber into which the flow containing the rejected mate-rial is directed when the plug of the separator is opened. The chamber is fitted with a discharge orifice. In this way, the reversed flow removes the obstruction in the re-ject orifice, thus preventing it from contaminating the accept mass.

Abstract: ABSTRACT      A lift crane having a separated transporter-supported front ring segment and a transporter-supported rear works including a counterweight.  The front ring segment is connected by a frame element to the rear works and supports a carrier which pivotally mounts a forwardly-inclined boom and a rearwardly-inclined mast.  Movement of the carrier across the front ring segment is permitted by two equal-length links pivotally connected to opposite sides of the carrier and the respective opposite sides of a horizontal bracket mounted on the frame element.  The center of rotation of the carrier as it traverses the front ring segment is substantially coincident with the imaginary vertex of a truncated isoceles triangle formed by the carrier and lines running axially along the links.  When the carrier is centered on the front ring segment, the center of rotation is also substantially coincident with a vertical axis running through the rearwardmost point of the mast.  Since the rearwardmost point of the mast is substantially coincident with the center of rotation, this point of the mast remains substantially stationary during the movement of the carrier across the front ring segment.  A pendant connecting the rearwardmost point of the mast to the rear works also remains substantially stationary and in a vertical plane during the movement of the carrier across the ring segment, thus minimizing the amount of side loads and torsional forces induced in the mast due to such carrier movement.

Abstract: "APPARATUS AND METHOD FOR PRODUCING A STILL IMAGE      VIDEO SIGNAL USING SOLID-STATE IMAGING DEVICE"                         ABSTRACT        A solid-state imaging device (16) exposed to incident light ray for a predetermined period of time is driven such that photoelectric conversion signals produced therein are read out twice or more.  The photoelectric conversion signals read out in sequence are added to each other such that two or more photoelectric conversion signals from each pixel are added to each other, to produce a resultant sum image signal.  The photoelectric conversion signals from the solid-state imaging device may be digitally processed such that A/D converted signal resulted from a first time reading out from the solide-state imaging device is stored in a memory (36), and this signal is added to a subsequently A/D converted signal resulted from a second time reading out.  In the case that the number of times of reading out from the solid-state imaging device is only two, the A/D converted signal resulted from the second time reading may be multiplied by a predetermined coefficient before addition.  In the case that a nonlinear quantization characteristic is given to the A/D converter (18), nonlinear-to-linear conversion is effected before addition.

Abstract: ABSTRACT          The present application relates to transporting data between digital computers by the use of a transcription computer that transports data from a source computer to a target computer.  A virtual terminal, which is a video terminal connected to the transcription computer, is used to virtually interact with the source computer and the target computer as their terminals at the application level, in that, the virtual terminal communicates and interacts with application programs of either the source or target computer.  By the use of a general purpose program stored and exe-cuted in the transcription computer, sequential data fields of sequential records of a data base of the application program of the source computer are automatically read from the source computer and stored in the trans-cription computer.  The data fields read are mapped to expected prompts of the application programs of the target computer.  As the target computer prompts, the transcription computer sequentially responds so as to auto-matically load the data of data fields of the records of the data base of the application program of the source computer into sequential data fields of sequential records of a data base of an application program of the target computer thereby automatically transferring data under a general purpose program notwithstanding differences in source computer architecture, target computer architecture, communications protocol and data base format.

Abstract: ABSTRACT       Arrangements for ultrasonic sealing comprising a sealing jaw      which is combined with an ultrasonics source      and a counterjaw    .  During the sealing the parts which are to be sealed to each other are pressed together between working surfaces of the jaws with simultaneous activation of the ultra-sonics source as a result of which the parts are welded together. In the sealing of thin material layers it is very difficult to obtain a uniform compression over the whole surface which means that the risk of burning asunder or unsatisfactory sealing increases.  In accordance with the invention this is prevented with the help of supporting elements      which engage with two stop faces      located in the nodal plane of the sealing jaw and on the one hand determine the minimum distance between the working surface, on the other hand orientate the flexibly suspended jaw so that the working surfaces are parallel.

Abstract: ABSTRACT               FINDING THE DIRECTION OF A SOUND    An arrangement for finding the direction of a sound in a medium has a thin shell structure having a circular symmetry.  The structure can flex in response to incident sound energy from the medium to perturb  the form of the structure.  A membrane of a piezo-electric material with an anisotropic piezo-electric response to distortion is arranged to be distorted by the perturbation of the thin shell structure.  The response of the membrane to this perturbation permits the direction of the incident sound to be indicated.  The membrane can be of polyvinylidene difluoride with anisotropic properties.  The membrane may be formed into a "dome" for example by fluid pressure inside a hemispherical shell closed by the membrane.
