Patent DE-2404771-A1 (DE)
Title: Automatic fitting seat belt - on sliding fitting on door and operated by door hydraulic stay
Inventor: RUEHMANN BERNHARD
IPC: B60R22/06
Filed: 1974-02-01
Abstract: One mounting point of the three point lap diagonal seat belt is fitted to the bottom rear edge of the car door. The mounting point is fitted to a sliding clasp which runs in a vertical groove in the car door. The clasp is powered by a hydraulic linkage operated by a large piston near the door hinges. This piston is attached to the stay which limits the amount the door is opened by. The system removes the belt from the wearer when the door is opened and provides easy access to the car seats with the door open. It also ensures that the seat belt is fastened at all times when the door is closed.

Title: Hydraulic load cylinder sealing system in testing machines - produces high pressure from piston cylinder to charge back pressure valve
Inventor: WASSILUK LEOPOLD
IPC: G01N3/02
Filed: 1974-02-02
Abstract: A pressure medium is supplied into a pressure vessel, to produce a pressure higher than the operating pressure of the load cylinder. The high pressure charges a back pressure valve, situated in the supply to the pressure vessel. The medium is supplied either via the cylinder, and the valve is subsequently closed by a sealing unit; or it is supplied via an external connection, after the valve has been closed. The system is esp. suitable for pressure vessels with gas-filled bubble type storages. The external pressure connection emerges at the valve seat, to which the valve is spring biassed.

Title: Antifouling coating for glass exposed to sea water - consisting of reticular metal support and coupling layer and copper (alloy) layers
Inventor: KOEHLER WINFRIED DR ING
IPC: C03C17/40
Filed: 1974-03-11
Abstract: Glass is coated with an antifouling agent for use in sea water by coating the surface exposed to the sea water with metal or reticular structure; the first layer e.g. of Ti, CrNi or another metal, acting as support and coupling layer on the surface, which is first roughened, e.g. by sand blasting, etching etc. The first metal layer is applied by spin coating or deposited from the vapour phase. This is followed by a second contact layer of Cu(alloy), opt. applied by electroplating, and then layers of Cu(alloy) applied by electroplating; the latter layers pref. being >=0.2mm. thick. The coated glass pref. is tempered at 200-300 degrees C. The edges of the structures should have a bond which is resistant to sea water. The toxic and distance effect can be controlled by varying the mesh size. The transparency of the glass is not affected and the coatings are relatively insensitive to mechanical damage.

Title: Vehicle lighting system using polarisation effect - uses double refracting material set in acrylic base to polarise or absorb light
Inventor: AGOSTINELLI ANTONIO
IPC: B60J3/06
Filed: 1974-03-25
Abstract: The system is for use on cars and other motor vehicles. It overcomes the danger of blinding the driver due to dazzle from undipped headlights. The effect is obtained by polarising the incident bundles of light rays or absorbing them. A doubly refracting material is used such as spar quartz, calcite, tourmaline or other similar anisotropic crystal. A carefully controlled finishing process is required. The crystals are embedded in plastic acrylic material and the resultant lenses can be used in glasses or goggles for pedestrians or drivers without windscreens. For motor cars it is recommended that the material is used for headlamp lenses, windscreens, rear windows and rear mirrors.

Title: Control system for fuel injection I.C. engine - senses speed and piston phase from rotating magnet
IPC: F02D41/36
Filed: 1974-03-28
Abstract: A magnetic rotor is built from two pairs of magnets.

Title: Corrosion test chamber with controlled temperature and humidity - uses central atomizer mixing compressed air and salt solutions and resistance heater
Inventor: MAYER XAVER
IPC: G01N17/00

Patent DE-2541862-A1 (DE)
Title: Electrochromatic display cell - filled with electrolyte contg heptyl-viologen cation
Inventor: JASINSKI RAYMOND JOSEPH
IPC: G02F1/1503
Filed: 1975-09-19
Abstract: Electrochromatic display cell is provided with two electrodes reversibly connected with a d.c. source, and is filled with an aq. electrolyte contg. a n-heptylviologen cation (0.14-0.16 M) and a prim. phosphate anion (pref. or bicarbonate anion. When d.c. is applied, the cation is reduced and forms on the cathode (display electrode) an insoluble, insulating, firmly adhering film, which absorbs a part of visible spectrum thus producing colouration. The colouration remains when the current is switched off, but disappears when the current is revered, because the product becomes oxidised and dissolves. Upon reduction, the shape of the display electrode is shown in red-violet colour. The colouration persists in the absence of electric current so that the device can be used for information storage. The colouring film can be formed very rapidly (10-50 msec). The redn-oxidn. cycle can be repeated many times due to the low concn. of the bromide ions which otherwise cause discolouration of the display electrode.
