Abstract: NEEDLED FIBROUS COMPOSITE. AND METHODS               ABSTRACT OF THE DISCLOSURE            A needled fibrous composite having thermal and acoustical insulating characteristics and methods of production thereof are provided. The composite structure comprises a substrate, a middle layer and a non-woven top layer.  The substrate may be in the form of a fibrous web or, alternatively, a thermoplastic film.  The middle layer comprises mineral fibers of a sufficiently short length to substantially preclude interlocking of any of the mineral fibers with other fibers of the structure and to provide the structure with desired flexibility.  The mineral fibers are present in a quantity sufficient to impart desired heat and sound insulating properties to the structure.  The top layer may be made of organic fibers or a substantially uniform fixture of organic and inorganic fibers. In making the inventive composite structure, the middle layer and the top layer are introduced onto the substrate, respectively. The three layers are thereafter consolidated, such as through needle punching. In addition, binders may be added to the composite structures so as to impart desired properties such as improved moldability.

Granted: 1992-11-10
Abstract: METHOD FOR DETECTING POSITION WITHIN THE MEASURING VOLUME OF A COORDINATE MEASURING MACHINE AND THE LIKE AND SYSTEM THEREFOR          ABSTRACT:    Axis  correction  or machine  characteristic data is stored (108) in memory (110) within a control or measurement processor  (36)  of a CMM (10)  (FIGURE 8).   The  axis  correction  data  includes  error  data representing 21 different geometry errors (FIGURES 4A through 4C)  of the CMM.  As position information is required,  the  measurement  processor  captures  the actual position signal from each machine axis sensor and uses this position signal to locate (112) a set of the axis correction data which describes the machine characteristics  at  that  position.   The  measurement processor then mathematically combines  (114)  (FIGURE 9)  the  position  signal  with  the  subset  of  axis correction data to obtain a corrected position signal having  a  corrected  set  of  coordinate values which describe  the  probe  position  in  a  true  Cartesian coordinate system.

Title: Expansion dowel assembly
Inventor: BERGNER ARNDT
IPC: F16B13/08
Filed: 1988-09-21
Granted: 1993-07-20
Abstract: ABSTRACT         An expansion dowel assembly is made up of an anchor bolt and an expansion sleeve laterally enclosing the bolt.  The sleeve is expanded by driving it in the axial direction relative to the bolt so that the end of the sleeve widens as it moves axially over a conically shaped expanding member on the bolt.  The axially extending surface of the expanding member is formed as a concave surface affording an increasing conicity in the driving direction.  Cutting teeth are formed on the outer surface of the sleeve and provide a saw-tooth section.  When the sleeve is driven relative to the bolt, the teeth cut into the surface of a bore-hole in a receiving material and form an undercut in the borehole surface.  To facilitate expansion, an annular groove is located in the outside surface of the sleeve adjacent the cutting teeth.  The annular groove is located on the opposite side of the cutting teeth from the leading end of the expansion sleeve.

Abstract: Abstract of the Disclosure In active range finder apparatus wherein an object to be inspected is illuminated by a laser source and light reflected by the object is detected in an imaging photo-sensor, a system is provided for increasing the dynamic range of the apparatus.  This system provides for integrat-ing over each of a series of measuring time periods light reflected from a window of the photosensor and hence proportional to the light received by such photosensor. When such integrated light exceeds a predetermined amount, a saturation signal is generated that immediately de-energises the source.  If this amount is not reached by the end of each period, the system is reset.  The source is gradually re-energised at the commencement of each subsequent period.  The virtually instantaneous de-energisation and gradual re-energisation combined with use of a saturation detector separate from the main photosensor ensures rapid action that is quick enough to substantially avoid saturation of such main photosensor.

The axis of the joint shaft is parallel to the longitudinal axis of the wiper blade.  A linkage is pivotally coupled to the retainer to drive the wiper blade across the curved surface of the windshield.  In the first embodiment, the joint shaft and wiper blade are prevented from rotation by a universal joint that is coupled to a fixed bearing by a connecting link. An elastic control link maybe operatively positioned between the fixed bearing and the connecting link, or the connecting link itself maybe elastic. In the second embodiment a lever having a universal ball and socket joint prevents rotation of the joint shaft and wiper blade.  In the second embodiment the ball and socket joint are coupled to the linkage by an extension that is guided for longitudinal movement either by the linkage or the ball and socket joint.

Title: Additive pcm speaker circuit for a time shared conference arrangement

Abstract: ADDITIVE PCM SPEAKER CIRCUIT FOR A TIME SHARED CONFERENCE ARRANGEMENT                 ABSTRACT OF THE INVENTION      A time shared multiport conference arrangement includes an additive PCM speaker circuit.  The additive PCM speaker circuit eliminates the need for loudest speaker detection and last speaker memory of conventional conferencing arrangements.  The additive PCM speaker circuitry operates in an on-line, real time environment to allow rapid combination of speakers' PCM voice samples.  Since the PCM voice samples are logarithmic in nature, they are not directly combinable.  The additive PCM speaker circuitry provides a storage medium which is preprogrammed with resultant values.  These resultant values each correspond to an additive combination of the values of two input speaker's PCM voice samples.  The additive PCM speaker circuit simplifies the complex processing logic usually associated with loudest speaker detection systems and thereby improves the real time operation of the conferencing arrangement.

Abstract: ABSTRACT OF THE DISCLOSURE Digital image data is encoded using a variable-length code which is described by a group of parameter values. Each parameter value describes a set of code values; each code value corresponds to a possible value of the data which is to be encoded.  When the data is encoded, the parameter values are appended to the encoded data.  A decoder stores the parameter values into a memory and then combines data values derived from the encoded data with parameter values from the memory to generate decoded data values.  Each code word includes a prefix which indicates a number of successive parameter values which are to be summed, and a population index which is to be added to the summed parameter values to produce a decoded data value.
