Title: Glasses for the production of extended refractive index distributions of high transparency
Inventor: POPP PETER DIPL CHEM
IPC: C03C3/14
Filed: 1988-02-05
Abstract: The invention relates to optical glasses which are suitable for the production of high refractive index differences of large lateral extension through ion exchange of M<+> ions (M<+>: Li, Na, K or Rb) by Ag<+> ions, where unusually low attenuations of light propagation in the regions modified by interdiffusion are achieved. The object is achieved according to the invention in that the oxidic glasses used in the ion exchange process have an alkali metal content of 20-35 mol% and a content of M<III>2O3(M<III> = B, Al or Ga) so that the M<III>2 O3 : M<I>2O molar ratio is >/= 0.8. The exchanged glass regions exhibit no significant discoloration up to exchange temperatures of 400@C although refractive index differences of from 0.1 to 0.15 are achieved. The attenuation ( lambda  = 632 nm) in the wave-transmitting layers produced is less than 1 dB/cm. These glasses are suitable for the production of inhomogeneous optical media in the area of imaging gradient optics or in optical waveguide microoptics.

Title: Process for connecting district-heating pipes
Inventor: BUENTE RUDOLF H F
IPC: F16L59/20
Filed: 1988-07-30
Abstract: In order to connect district-heating pipes (1; 2) which comprise a steel medium-channelling pipe (3), a plastic casing pipe (4) and a foam filling (5) therebetween, the medium-channelling pipes (3), which are exposed at the ends, are welded (6) in a known manner. A sleeve (8), e.g. consisting of aluminium sheet, which surrounds the gap of the foam filling (5) is then laid around the ends (7) of the two adjacent foam fillings (5) and the cavity is subsequently filled with foam (14). Thereafter, an intermediate piece, of the casing pipe (4), which has a longitudinal cut through it is fitted over said foam-filled cavity, welded to the two adjacent casing pipes (4) and welded at the longitudinal cut. In this arrangement, the existing foam filling (14) serves as a supporting means, with the result that the intermediate piece does not shrink and settle at the longitudinal seam as a result of heating. <IMAGE>

Title: Disc/dowel system
Inventor: BRUSNOWITZ GEORG DIPL ING
IPC: F16B13/08
Filed: 1988-08-02
Abstract: When configured from metal or plastic, the dowel system is intended to produce frictionally locking connections. If heat-resistant connections are required, the metal-dowel system is necessary. The number of disc units (2 discs in each case) is decisive for determining the withdrawal forces. By empirical tests with various materials, the maximum contact-pressure force onto the bore walls can be determined. The production of the contact-pressure force can be controlled by a torque wrench.

Title: Plastic adjusting screw, in particular for adjusting devices of motor vehicle headlights (headlamps)
Inventor: DAUMUELLER HANS
IPC: B60Q1/068
Filed: 1988-10-22
Abstract: A plastic adjusting screw (4), in particular for adjusting devices of motor vehicle headlights, has a shaft (5) which has an outer thread and interacts with a nut part (3). The shaft (5) is provided with a longitudinal slot (12) which divides the shaft (5) into two halves (14, 15).

Patent DE-3928828-A1 (DE)
Inventor: NOHSE DIETER DIPL ING
IPC: H04H20/00
Filed: 1989-08-31
Abstract: In the radio data system, transmitting stations having the same programme identify themselves by transmitting the same PI code. If the programme is regionalised at particular times of the day within one programme chain, the PI code should be switched over. However, there are transmitting stations which always radiate a regionalised PI code, even when they are transmitting a joint general programme at times via the individual transmitting stations. To avoid an additional operating control at the RDS receiver which can lead to operating errors, a mobile RDS receiving set is presented in which, when a regional programme chain is lost, the alternative frequencies stored from earlier receiving routines are examined to see whether another regional programme of the same transmitting station can be received which is then tuned in by preference and is accepted as part of a new programme chain. <IMAGE>

Patent DE-4014088-A1 (DE)
Title: Saturating water with air or gas - by passing water through vessel contg. chamber from which part of water is circulated through centrifugal pump
Inventor: KURTZE INGOLF
IPC: B01F5/10
Filed: 1990-05-02
Abstract: In saturating water with air or gases, the water passes through a container into which a chamber (3) with an upper vent (9) has been built. A part of the water flow passes through the lower inlet opening (2) of this chamber (3), and is withdrawn from the chamber (3) by a centrifugal pump (4) and passes through a pressure pipe (5) having a number of branches. One of these branches leads to the suction side of the pump (4) and contains a nozzle (6), pump or valve for the supply of air or gas, and this air or gas is finely dispersed in the water due to the drop in pressure. A second branch (7) has a nozzle, pump or valve by which the air- or gas-saturated water is supplied to a water treatment plant, flotation vessel or aeration tank. A third branch (8) contains a pressure reducer in the form of a valve, a perforated plate or an adjustable pressure regulator and is used for returning air- or gas-saturated water to the chamber (3). USE/ADVANTAGE - This invention is used for producing water which is saturated with air or gas, such as is required for example in certain water treatment plants. The proposed system simplifies the regulation of the air or gas flow and automatically removes any excess air or gas which has been added. The air or gas is finely dispersed in the pressure reduction process so that the saturation process begins inside the centrifugal pump, and the saturation process is therefore improved so that the deg. of saturation produced approaches the theoretical max. value.
