Patent DE-3008419-A1 (DE)
Title: TV colour tube phosphor stripe application method - has dual light source utilising exposure to electro-sensitised layer for phosphor colour carrier fluid application according to charge level
Inventor: JUNGINGER HANS-GEORG DIPL PHYS
IPC: H01J9/227
Filed: 1980-03-05
Abstract: The electrophotographic method uses a photoconducting layer of the inner front surface of the tube is charged to a high potential and exposed to light sources behind correction lenses and a colour strip selection electrode. Appropriate fluid and adhesive solutions are used to contain the phosphor in the appropriate charged area, the fluid flows off the uncharged sections. After each liquid 'development' the stripe is dried and the process repeated for another colour stripe. Two light sources (L1, L2) displaced from one another provide the exposure through a colour selection electrode (M) which is a mask containing apertures (W) which are larger than the rebates (V). The inner surface of the tube (1) has an electrode layer (2) of thin aluminium or polyinylalcohol substance with potassium silicate or conducting polymer. The photosensitive layer (3) covers the electrode (2) and is charged prior to exposure through the mask (M). The exposure results in an intensity profile in the photosensitive layer according to exposure from one or both light sources so that the blue exhibits the highest value (H), the red (R) and green (G) a half value (H/2) and a spacing layer (D) has a value less than 20% of the maximum (H). The intensity profile is used in the development process so that the correct phosphor stripe (4) is retained over the correct charge stripe after exposure.

Title: Powder mfr. from molten material - using two atomisers and two drop shafts for one melting chamber
Inventor: RUETHARDT ROLF DR
IPC: B22F9/08
Filed: 1980-09-13
Abstract: Powder material is produced by melting a substance in a melting chamber in a non-oxidising atmos. and by pouring the melt through an atomiser into a drop shaft to cool the atomised particles as they descend. At least one other drop shaft is arranged in parallel to the first and can be served by the same melting plant.

Title: Double-chain bracing fitting for high-voltage overhead lines
Inventor: HILGARTH GUENTHER PROF DR ING
IPC: H02G7/20
Filed: 1981-02-23
Abstract: A double-chain bracing fitting for high-voltage overhead lines consists of a frame (1), which can be arranged between the two bracing chains (4, 5) and the overhead line, and of a damping device (12) which dissipates energy and is connected on one side to a point (6) which is fixed to the frame and moves if one of the chains cracks. It is intended to create a capability for protecting that insulator chain which remains in the event of a chain cracking against being overstressed, which capability can be used generally, especially in the case of rigid triangular double-chain bracing fittings as well. For this purpose, the damping device (12) is connected at its other end to a fixing mass (8) which is supported in a loosely moving manner on the bracing fitting. In contrast to the known additional masses, the fixing mass is not firmly connected to the bracing fitting but is supported in a freely moving manner on the bracing fitting so that, in the event of one chain cracking, a relative movement takes place between the bracing fitting and the fixing mass (8), which is used for application of the damping device (12). <IMAGE>

Title: Headlight, in particular fog headlight, for motor vehicles
Inventor: SCHMID HEINRICH
IPC: F21S8/12
Filed: 1981-09-25
Abstract: The transverse luminous element (14) of the incandescent lamp (13) is arranged at right angles to the optical axis (15) of the fog headlight, and defocused by the amount (19) with respect to the reflector (10), which is produced from plastic, in the direction of the apex of said reflector. This defocusing (19) has the effect that the low-beam cut-off (18, 28) of the emitted light beam is not displaced upwards - something which is due to the deformation of the reflector (10) and conditioned by its heating. As a result, dazzling of oncoming traffic is avoided, and the sharpness of the low-beam cut-off is not reduced. <IMAGE>
