Title: Superimposing audio signals on pre-recorded video tape - using multitrack tape with audio signal inserted in space between adjacent video tracks
Inventor: MANGOLD HANS DIPL ING
IPC: H04N9/802
Filed: 1979-12-14
Abstract: The recording system is used to enable subsequent editing of audio information onto a tape already recorded with video. The facility is provided by employing the normally free space between video signal tracks (10,11) for recording the sound track (12). There is an azimuth displacement between the video and audio recording. The record-replay heads for video and audio tracks are close together and have the required azimuth displacement. A simple compensation circuit connected between the two heads eliminates disturbance between channels. The circuit operates by suitable phase and amplitude modification of the disturbing signal. The editing facility is thus provided without the need for increased tape area, and without disturbing effects on the recorded video tracks.

IPC: A43B21/32
Filed: 1980-06-03
Abstract: A mouldable foot wedge, when suitably treated as by heat, becomes deformable so that the person for whom the wedge is to be customed fit is allowed to stand on the wedge. This deforms the wedge to conform identically to the contour of the person's foot, thus filling voids. An area below the rear heel on one side is defined as a plug which is not subjected to the heat treatment. A beneficial cant of inclination can be provided to the wedge by not allowing this cold plug to be heat treated and thus deformed.

Title: Motor vehicle clutch disc with torsional vibration damping
Inventor: WANZUNG FERDINAND ING GRAD
IPC: F16F15/126
Filed: 1981-02-27
Abstract: The invention discloses a motor vehicle clutch disc with torsional vibration damping, in which torque-dependent damping, speed-dependent damping and both types of damping together are possible. For this purpose, the clutch disc has a hub part, a supporting disc and a flexible element which connects the supporting disc to the hub part. Friction elements are arranged between the hub part and the supporting disc. In torque-dependent damping, the flexible element is deformed and the supporting disc is moved in the direction of a flange of the hub part, acting on the friction elements in the process. For speed-dependent damping, the flange of the hub part has on its upper edge resilient segments which move in the direction of the supporting disc due to centrifugal force and act upon friction elements mounted there (Fig. 2). Ventilation slots in the flange allow cooling of the flexible element. <IMAGE>

Title: Method for the determination of hydrogen peroxide
Inventor: RUBISCHUNG PETER DR
IPC: C12Q1/28
Filed: 1981-04-13
Abstract: The invention relates to a method and diagnostic reagent for the determination of hydrogen peroxide or of substances which react to form hydrogen peroxide and of peroxidase and substances with peroxidase activity by measuring the colour formed by a chromogen, characterised in that the chromogen used comprises substances of the general formula I dissolved in solvents of the general formula II, in which     R1 and R2 are hydrogen or a lower alkyl group,   R3 and R4 are a lower alkyl group and   R5 and R6 are a lower alkyl group or aryl group,   X is C or S.   <IMAGE> Substances of the general formula I are oxidised in aqueous media by atmospheric oxygen or hydrogen peroxide to highly coloured compounds. These aqueous solutions are, however, unstable. Furthermore, sulphoxides are easily converted by hydrogen peroxide into sulphones. Surprisingly, it has been found that it is possible, using the chromogen solution according to the invention, to determine hydrogen peroxide or substances which react to form hydrogen peroxide quantitatively and with extremely high sensitivity via the colour of the solution.
