Title: Method of identifying the material of spectacle lenses
Inventor: VIEWEG WALTER
IPC: G01M11/02
Filed: 1987-07-21
Abstract: In a method of identifying the material of spectacle lenses for the purpose of replacing such lenses in optical businesses, provision is made to measure the refractive index of the lens. Preferably, the dioptric power of the lens to be examined is first measured in the usual way by means of a dioptric measuring device and then the dioptric power is measured with respect to a second medium, which lies right against both sides of the lens and which is bounded in a plane-parallel fashion on the outside at right angles to the optical axis. <IMAGE>

Title: Mining gypsum
Inventor: HOELTER HEINZ DIPL ING
IPC: C04B28/14
Filed: 1987-09-09
Abstract: The invention describes the protection of building materials containing gypsum or consisting of pure gypsum and also calcium sulphate dihydrate as packing material for underground mining against the action of anaerobic bacteria (H2S liberation), which is characterised in that the materials have added to them alkalis or alkaline earth compounds such as NaOH, Na2CO3, CaO, Ca(OH)2 etc. to increase the pH to greater than pH 11 and, additionally, oxygen-liberating agents such as, for example, potassium persulphate, perborates etc. which, in the alkalinity of the compositions, slowly release the oxygen and thus prevent the liberation of hydrogen sulphide by anaerobic bacteria.
Patent DE-3732779-A1 (DE)
Title: Camouflage material for radar, infrared and millimetre wave detection - comprises mixt. of pulverised semiconductors and ferrite(s), embedded in neutral material e.g. resin
Inventor: ORTENBERG MICHAEL VON PROF DR
IPC: H01Q17/00
Filed: 1987-09-29
Abstract: The camouflage of objects to prevent their detection by infrared, radar or millimetre waves is based on a mixture of several semiconductors and ferrites which are pulverized to granules or powder and mixed to form a homogeneous constitution.  This mixture is embedded in dielectrically neutral material (plastic or resin) or a similar binder before application. The average particle size should be less than the shortest wavelength of the millimetre waves, against which the camouflage is to be active. It should also have a low emissivity for the infrared range of 3-5 microns or 8-14 microns. ADVANTAGE - Such a camouflage material would be satisfactory for military purposes.

Title: Method for producing appropriately contoured carcasses for pneumatic motor vehicle tyres to be mounted on the radially inner circumference of a rim
Inventor: NAEDLER HEINRICH
IPC: B29D30/32
Filed: 1987-11-12
Abstract: Method for producing appropriately contoured carcasses for pneumatic motor vehicle tyres to be mounted on the radially inner circumference of a rim. These tyres are mounted on rims with radially inwardly pointing rim flanges. They have beads which are built up from cord plys wrapped around a bead core and with tyre side walls which have smooth, sealing bead seat faces. In order to build up a tyre side wall, a contour ring which corresponds to the contour of the bead seat face is wrapped axially from the outside onto the previously built-up bead. The cord plys are folded over around the contour ring, the bead seat face being brought into contact against the contour ring. The final vulcanisation takes place with the contour ring resting against the bead seat face.

Title: Sampling system for determining the SO3 and NH3 content of flue gases
Inventor: WURZ DIETER PROF DR ING
IPC: G01N33/00
Filed: 1987-12-07
Abstract: A sampling system for determining the NH3 and SO3 content of flue gases having a probe which can be moved along a measuring section in a flue gas channel or the like is characterised in that the system components serving to quantitatively separate out NH3 and SO3 are arranged in the movable probe. This makes superfluous long glass lines which can hardly be mounted, in particular, in flue gas channels having large dimensions. The sampling system proposed is, in respect of expense and measurement accuracy, superior even to a sampling system having numerous probes statically arranged in the flue gas channel.

The gears 3, 6 are in the form of crown gears. The swash-plate gear 3 may additionally be formed as a spur gear (see Figs 3 & 4) having teeth meshing with a surrounding stationary internally toothed member (19). The gear mechanism may be used for adjusting a vehicle seat back. <IMAGE>
Patent DE-3811360-A1 (DE)
Inventor: BRUNNER THOMAS
IPC: C11D1/65
Filed: 1988-04-02
Abstract: The removal of stains from fabrics is difficult because of the different chemical composition of staining substances, which extends from plant juices to coloured pastes, for example ballpoint paste. To date, stain removers suited to the particular staining substance have been employed both domestically and in commercial cleaning. Since the customary stain removers contain volatile, often flammable solvents, a possibility for long action times, which in conjunction with water brings about reliable washing out of the coloured pigments, has been achieved by treatment with stain removing components which do not contain volatile solvents.

Title: Self-adapting filter for measuring devices
Inventor: KUCHARZEWSKI HARRO DR ING
IPC: G01R15/00
Filed: 1988-05-02
Abstract: The preferred field of use of the invention are measuring devices installed on board of seagoing ships. The special object is largely to eliminate interfering influences caused by the wave sequence. For this purpose, it is proposed to connect two low-pass filters in series and to combine these low-pass filters with adaptation circuits. This makes it possible to counter any increases which occur in the noise value amplitude and to achieve a setting of the dead zone.

Patent DE-3815074-A1 (DE)
Inventor: ZIEHER PETER
IPC: G01D5/22
Filed: 1988-05-04
Abstract: In the device disclosed, four coils (11 to 14) are mounted on the inner wall of a support (10) made from an electrically non-conductive material and co-operate with a conducting part (20) provided with regions (21, 22) made from an electrically conductive material. The conducting part (20) is symmetrical in shape and has two regions (21, 22) which are larger than one of the coils (11 to 14).
