Title: Hot-welding device
Inventor: M SCHOTT JUN CHARLES
IPC: B29C65/74
Filed: 1969-10-20
Abstract: Feed device comprises a small-diameter elongate coil which extends parallel to and entire length of hot-welding bar and is set on one side of it. On opposite side is tightener to keep protective sheet under uniform tension so that sheet can leave coil, pass under hot-welding surface, to come back to tightener. Coil's support has faces under coil spaced at many points or, preferably, spaced continuously along coil's length. Faces operate on face of protective sheet and support coil by preventing it bending and are applied to sheet pressing it uniformly against hot-welding surface. Applications are hot-welded sheets.

Abstract: 1303808 Formant tracking vocoder PLESSEY CO Ltd 22 April 1970 [24 April 1969] 21000/69 Heading H4R  In a formant tracking vocoder, Fig. 1, speech SP is fed to two channels to derive two formant frequencies of speech. Each channel includes a band stop filter F -1  or F -2  tuned to reject one formant frequency and a frequency discriminator F 2T  or FIT to detect the frequency of the other formant. The output of the discriminators in each channel are utilized to tune the band stop filter in the other channel to reject the appropriate formant. A third channel may be provided including two band stop filters F -11  and F -22  to reject the two formants, each being tuned by the appropriate discriminator output, in order to provide a signal in which the pitch frequency can easily be determined by discriminator C 0 . Each formant discriminator may include a band reject filter with a phase sensitive detector connected between input and output with the integrated output of the detector controlling the filter tuning, and providing the discriminator output. In this arrangement the output from the band reject filter is a suitable signal from which the pitch frequency can be determined.  Three formant tracker, Fig. 4.-The channel which includes the filter F -2  to reject the middle formant is fed to low pass and high pass filters LP1 and HP1 in order to separate out the lowest and highest frequency formants which are detected by respective discriminators. The outputs from these discriminators control respective filters F -1  and F -3  in the other channel in order to detect the middle formant. The three discriminator outputs control band stop filters F -11 , F -22  and F -33  in the pitch discriminator channel.

Title: Push-button keyboard with conducting elastic membrane - operates by finger pressure and connects with contacts by lateral motion
Inventor: LIEDTKE RAINER DR MED
IPC: H01H13/703
Filed: 1973-08-31
Abstract: The push-button keyboard, for generating control pulses, consists of an elastic conducting membrane on top of an insulating board which has large cavities and smaller holes. The membrane passes straight across the tops of the large cavities but dips down into the holes. Conducting rings are located around the rims of the holes and are insulated by washers from the membrane. The operator's finger forces the membrane down into the large cavity and draws the dipped part of the membrane sideways so that it touches the edge of the conducting ring around the hole. The outer surface of the membrane is covered with an elastic insulator.
