Title: Optic fibre ends - are tapered for two or more to be coupled to an optical detector
Inventor: MALTZ GEORG
IPC: G02B6/38
Filed: 1992-02-01
Abstract: To prepare the ends of lightwave conductors, for coupling to optical detectors, the end sections of two or more conductors and optic fibres are tapered. They are inserted into a protective shrouding. The optic fibre ends are pref. tapered by etching in a buffered liq. acid soln, through drawing out slowly for the ends to be reduced by the acid for a longer time to give the tapering effect. Two or more optic fibres are tensed, in parallel to each other, by draw tension and heated to a level just below the m.pt. and are fused together in a round cross section. The fibres are tapered to twice the core dia. The molten section is cut in the centre. The tapered ends are adhesive bonded in the pins of an optical plug, or are inserted into conical, and especially trumpet-shaped drillings and hyperbolic drillings. The tapered ends are inserted into dedicated drillings in the plug pin, with drillings aligned at an acute angle to each other. USE/ADVATAGE - The technique is for coupling lightwave conductors to detectors where optical signals are to be converted to electrical signals in optical information systems, where the conductors have a typical dia. of 125 microns with a light-conducting core dia. of 8-10 microns for use with semiconductor diodes as the detectors. The system allows two or more lightwave conductors to be coupled to a small detector surface of less than 100 microns.

Title: Ventilation control for car interior - automatically opening fresh air inlet flaps when carbon di:oxide concentration inside is less than outside
Inventor: RIEHL GUENTHER DIPL ING
IPC: B60H3/00
Filed: 1992-05-26
Abstract: To control the ventilation of a car's interior, the ventilator itself is regulated in proportion to the toxicity of the external air and the internal air. As a measure of toxicity, the concentration of carbon dioxide is used, the concentrations inside and outside being compared. As a result of this comparison, a first control signal is generated to open the fresh air inlet flap, and a second control signal to close this flap. The control signals are generated by a hysteresis switching circuit, whereby the opening signal is given when the internal carbon dioxide concentration exceeds the outer by a preset amount. The closing signal is given if the external concentration reaches the internal value. ADVANTAGE - Automatic ventilation control dependent on carbon dioxide concn.
