Inventor: RICHTER GUNTER
IPC: B29C48/475
Filed: 1990-01-25
Abstract: The invention relates to a method for discontinuously manufacturing multilayered coextruded tubular preforms made of thermoplastics for forming large-volume, multilayered hollow articles in a split blow mould, in which at least two different, annular material melts are brought together centrally within the annular ram one after the other and in the direction of extrusion to form a multilayered material melt and in which this multilayered material melt flows outwardly in the shape of a funnel into an annular accumulating space and is subsequently discharged by an axially movable annular ram, which acts as a coextrusion head and is forced upwards by the multilayered material melt, via an annular die gap, so that the individual material melts are deflected out of their extrusion direction and flow radially into the corresponding flow channels before their entry into the coextrusion head. 
<??>In order to improve the known method in such a way that cross-sectional changes no longer occur in the transitional area between the respective extruder and the annular ram, so that weak points are avoided or are reduced to such an extent that they no longer have an adverse affect on the finished hollow article, it is proposed that the individual material melts are deflected out of their extrusion direction and flow radially into the corresponding flow channels of the annular ram before their entry into the coextrusion head.

Patent CA-2012549-A1 (CA)
IPC: H04N7/171
Filed: 1990-03-19
Abstract: A baseband television signal having a video portion with a suppressed horizontal sync pulse is descrambled by using a variable attenuator.  The attenuator shifts the level of predetermined portions of the signal to restore the suppressed horizontal sync pulse to a normal unsuppressed level with respect to the rest of the signal.  A reference voltage is derived from a blanking level potential and sync level potential of the signal, and is equal to the zero carrier level of the video portion of the signal.  The reference voltage is utilized to maintain the level of the restored sync pulse at a proper value.

Filed: 1990-06-01
Abstract: A filter for use with a signal which varies about a mean such as in a radioactive densometer, is provided and includes a microprocessor and timing clock for sampling the random variable over a specific time interval. The microprocessor utilizes a weighting factor which is used to determine a percentage of an average frequency of an initial sample of random signals or mean. Further, the microprocessor determines a percentage of an average frequency of a subsequent sample of random signals. Once determined, the two percentages are added together yielding a new frequency which the microprocessor then uses to decide if an actual change in state has occurred.
