Patent DE-2845173-A1 (DE)
Title: Eye testing device measuring pupil spacing - is used to set optical centres of corrective lenses at same distance apart
Inventor: SCHOTTLER AXEL
IPC: A61B3/11
Filed: 1978-10-13
Abstract: The ophthalmic device measures the spacing between the left and right pupils via a pair of light beams, which are projected directly onto the cornea of each eye. Each beam provides an fine sharply defined optical mark on the cornea, the position of these being adjustable, so that the pupil spacing is provided by the required amount of adjustment read from a scale. Pref. the patient rests the bridge of his nose on a support at a given distance from the device. The respective beams are directed onto the right and left eye, one at a time with the other beam being blocked via an opaque disc. The optical mark provided by the beam is adjusted between two limits, so that it is aligned with the centre of the pupil, by rotation of an adjustment knob allowing parallel shifting of the beam. The spacing between the pupils is determined from the amount of adjustment of each beam, which may be read from a combined scale. the measurement is free from parallax errors and is not dependendent on the distance between the pupils of the person performing the testing.

Title: Light reflecting coating application - by heating plastic foil carrying glass beads in adhesive layer under vacuum
Inventor: OHLERT WOLFGANG
IPC: D06Q1/10
Filed: 1978-12-22
Abstract: Umbrellas, made of a light reflecting material, make a pedestrian carrying one, even when folded up, clearly visible to any car driver in the dark. A carrier foil, e.g. PVC, is coated with minute 30-40 mu) glass beads, half coated with a reflecting Al layer by using a fusible adhesive. Shapes (trianges, circules) are cut from this and applied to the umbrella material. When this is heated briefly in a vacuum chamber, the carrier foil patterns form a lasting bond with the umbrella material. This makes the umbrellas washable and the reflective particles cannot crumble away even after repeated folding and unfolding of the umbrella.
Patent DE-2856317-A1 (DE)
Title: Bonding rail for glazing sheets - contains desiccant chambers and is coated with adhesive, esp. for making spacer frames for double or multiple glazing
Inventor: FRANKE CHRISTIAN HERMANN
IPC: E06B3/677
Filed: 1978-12-27
Abstract: The rail is used to form a spacer frame between two glass panes, esp. in double- or triple-glazing, so an airtight cavity is formed between each pair of panes. The rail possesses chambers contg. a desiccant(6) removing moisture from the cavity, and is coated on both sides with an adhesive forming sealed joints with the panes. The rail is pref. made of plastic or natural rubber, and may be rigid or elastic. Both layers of adhesive are pref. covered with a protective strip which is removed immediately before bonding the rail to the panes; another protective strip pref. covers the holes leading to the desiccant chambers. The rail can be stored as a roll or coil many meters in length, and cut when required. It is then only necessary to remove the three protective strips. Multiple glazing can thus be undertaken by amateurs, i.e. "do-it-yourself" workers.

Title: Quick-break mechanism stopping short circuit currents - has two disconnection devices in parallel with auxiliary arc extinguisher
Inventor: BRUECKNER PAUL PROF DR ING DR
IPC: H01H85/46
Filed: 1979-07-28
Abstract: The circuit rapidly breaking short circuit currents has a first break point (14) in series with a second break point (32). The main current path (33) carrying the rated current during normal operation is in parallel with the auxiliary arc extinguishing arrangement (17).

Title: Plastic insulated cable - produced with copper wire braiding applied over viscous fluid film followed by methylcellulose powder
Inventor: MADRY PETER DIPL ING
IPC: H01B13/00
Filed: 1979-12-04
Abstract: An electrical power cable for medium and high voltages with a moisture-proof plastic insulation is produced by surrounding the insulation with a film of an insulating oil (boron oil). The metal (copper) wire braiding is then applied and the core is passed through a fluidised bed of a powder which swells under the access of moisture (methyl cellulose). A tape of metal and a tape of insulating foil are wound around the core before the final insulation (PVC) is extruded over it. The result is that even moisture which has entered through external damage can only have an extremely localised effect.
