Title: Electro-magnetic induction heating apparatus
Inventor: HEYES PETER J
IPC: H05B6/10
Filed: 1990-01-29
Abstract: ABSTRACT            ELECTRO-MAGNETIC INDUCTION HEATING APPARATUS            An electro-magnetic induction heater has a heating coil which defines a throat through which a metal strip (moving towards a plastics film laminating station) passes thereby to be heated to a laminating temperature.  The coil turns are flexible, and are braced at spaced positions in braces which are mounted for movement towards and away from the metal strip.  Each brace has an associated adjustment means.  The positions of the respective braces are adjusted during heating, preferably automatically, so as to adapt the coil throat shape to the varying cross section (and/or other characteristics) of the strip to be heated, thereby to ensure uniform temperature distribution across the width of the strip. Under automatic control each adjustment means is operated in closed loop manner by associated actuating means in response to deviation from a reference level of a sensed temperature signal provided by an associated sensor positioned adjacent the emergent heated strip.     Refers Figures 4 and 5.     58:cl-27mus

Title: Process and equipment for the continuous production of inorganically bonded materials
IPC: B28B1/52
Filed: 1990-08-24
Abstract: A method and device for the continuous production of moulded elements from inorganically bonded materials is presented. This involves compressing a strand of material in a high-pressure compressing unit in such a way that its thickness is less than the set thickness of the finished strand of material and its density is greater than its set density. In the following calibrating device, no active pressure application takes place. It is essential here that, after leaving the high-pressure compressing unit (2), the strand of material runs through a pressureless zone (5) and, following that and immediately before entering the calibrating device (4), is compressed to such an extent that the recovery occurring during running through the pressureless zone (5) is either completely eliminated and the density of the strand of material is greater than the set density of the finished strand of material and the thickness is less than the set thickness of the same when entering the calibrating device (4) or the recovery is eliminated only to such an extent that the thickness of the strand of material corresponds to the set thickness and the density of the strand of material corresponds to the set density of the finished strand of material.

Abstract: METHOD OF LASER MACHINING MOLDS WITH MICROTEXTURED SURFACES                         ABSTRACT         A process is provided for preparing a three dimensional object such as a mandrel for forming envelopes for mammary prostheses or other implantable medical device by dipping the mandrel, etc.  The envelopes are provided with micropillars on the exterior surface which resembles the mandrel surface in negative relief.  According to the process a workpiece of solid stock material such as polymer is provided in the shape of the desired prostheses.  It is positioned for rotation on a supporting shaft or other holding mechanism.  A pulsing laser beam, directed at the workpiece is moved in a plane parallel to the axis of rotation of the workpiece while the beam is maintained approximately perpendicular to the workpiece surface.  The rate of pulsing of the laser beam and the speed of rotation of the workpiece are controlled to produce patterns of blind micro-holes on the surface of the workpiece.  A noncircular pattern can be produced by oscillating the beam toward and away from the axis of rotation with each revolution of the workpiece.

Abstract: ADAPTIVE DIGITAL FILTER INCLUDING LOW-PASS FILTER                 ABSTRACT OF THE DISCLOSURE       An adaptive digital filter for estimating a response characteristic of a signal path by monitoring a sampled output signal of the signal path, estimating a predetermined number of filter coefficients which represent the response characteristic of the signal path, and generating an estimated output signal of the signal path using a plurality of successive sampled input signals of the signal path and the estimated filter coefficients, where the estimation is carried out so that a difference between the output signal and the estimated output signal is reduced. Each of the filter coefficients is extracted by a low-pass filter where the low-pass filter coefficient in the low-pass filter can be set to a constant. Normalization can be carried out in either the input side or the output side of the low-pass filter. Otherwise, the low-pass filter coefficient may be set to 1-K?Xj(m)2/r, where r is set equal to a norm of the sampled input signals in the beginning, and is then set to an integrated power of the sampled input signals.

Title: Embedded coding system for video signals
Inventor: HASKELL BARIN G
IPC: H04N7/26
Filed: 1991-01-17
Abstract: An Embedded Coding System for Video Signals Abstract A video processing system is disclosed that separates and separately encodes and decodes the low and high spatial frequency coefficients of images for transmission or storage. Each block of an image is transformed into the frequency domain. High frequency coefficients of the resulting transform matrix are separated from the low frequency coefficients. The low frequency coefficients are motion prediction compensated to derive motion vectors and a prediction error signal. The motion vectors, prediction error signal and high frequency coefficients are channel encoded for storage or transmission (FIG. 1). In a receiver, the motion vectors and prediction error signal are used to reconstruct a low frequency motion-compensated version of the image. The high frequency coefficients are inverse transformed into the pel domain and are combined with the reconstructed low frequency version of the image to reconstruct a version of the original image (FIG. 2).
