Title: Fast and accurate signal processing for infrared radiometry - uses an analogue multiplier to chop the waveforms
Inventor: ROTHDACH WOLF-PETER DR MED
IPC: G01J5/62
Filed: 1975-01-29
Abstract: The fast and accurate method is for processing the signals detected in certain types of heat or infrared radiometry applications, in which an analog multiplexer is used to produce chopped waveforms, with advantageous shapes. Signals produced from radiometry transducers have traditionally been chopped for further processing, and the chopped signal contains useful information in both its amplitude and phase. The method solves certain associated noise problems. The radiometer transducer output is generally of a sinusoidal shape, and this signal is amplified in a low noise preamplifier (VV). This is then applied to one input of the analogue multiplier (AM) to the other input of which one of several alternative waveforms may be applied. An adder subtractor element (A/S-V) is also incorporated in the network, and this feeds a display unit (AZ).

Title: Extrusion or injection of polymers, maintaining orientation - with temp and velocity gradients imposed on streams in melt
Inventor: COGSWELL FREDERIC NEIL
IPC: B29C48/07
Filed: 1975-06-13
Abstract: Whilst a polymer is being extruded, a velocity gradient is imposed on the melt in such a way that (part of) the flow is accelerated in the direction of extrusion, and polymer molecules are oriented in that direction. During this acceleration, a temp. gradient is also imposed upon the flow in such a way that part of the flow is subjected to a temp. above, whilst another part of the stream is subjected to a temp. below the critical temp. and a part of the stream lying between the two is accelerated at the critical temp. which leads to the maintenance of the orientation in the prod. A cooling arrangement positioned in the melt channel, in the zone of the inlet to the extrusion die, sets up the temp. gradient and divides the single stream into separate streams which flow together again at the threshold of the die. Method ensures maintenance of orientation in the finished prod.
