Title: Electrical plug socket moulding - using soft polymer around cable and hard polymer around contact elements
Inventor: LEPPERT KURT DIPL ING
IPC: B29C45/14
Filed: 1979-06-27
Abstract: Electrical plugs or sockets are manufactured by joining the electrical cable to the plug pins or socket sleeves by casting insulating material around them in a mould. The mould has two pouring gates so that insulating material of harder consistency can be injected around the contact parts, and of more flexible consistency around the handle in the cable end. The preferred material is either polyurethane for the hard and PVC for the soft part, or PVC of different Shore hardness for both parts. This produces a low-cost plug socket of good strength and flexibility.

Title: Upgrading method for recorded video colour quality - transfers luminance and chrominance signals in separate consecutive frame periods
Inventor: HEITMANN JUERGEN DIPL ING
IPC: H04N9/81
Filed: 1980-06-03
Abstract: To obtain high quality reproduction from picture information stored on magnetic tape it has been found advisable to broadem the bandwidth available for colour recording. This can be done by an arrangement whereby first the luminance information for each picture frame is recorded and then the chrominance information. The synchronising clock and colour burst pulses are provided by a clock generator applied to the output signals which is derived from the colour matrix circuit. The d.c. signal level corresponding to the average grey luminance is added to each red, green,blue output signal in summing circuits. Two of the signals are passed to a change-over switch with the result that during the first half-frame only the first signal is passed on to the output and, during the second half-frame, only the second signal is passed on. Another change-over switch connects the luminance signal to the magnetic tape recorder input for a full frame period. Whereas the two other are recorded during the immediately following full frame period.

Title: Bucket wheel pneumatic mine filling machine dust suppression - involves separately filled and closed chambers in hoppers feeding air duct
Inventor: SCHUMACHER LUDGER
IPC: E21F15/10
Filed: 1980-06-23
Abstract: The lining in a delivery hopper prevents escape of air containing dust. The system is used for suppressing build-up of dust when operating bucket-wheel pneumatic backfilling machines in a mine, esp. machines used for blowing anhydrite or similar fine material into a blower duct. With one or more bucket wheels interposed, the blown air duct is supplied with powered material via multiple delivery hoppers, or a single one containing compartments which can be separately filled and closed. They can be filled via a shared conveyor with hoppers, conveyor, and if appropriate, a bunker combining to form a gastight sealed system. This permits continuous operation, with dust almost completely suppressed.
