Patent DE-3138588-A1 (DE)
Title: Reflector arrangement
Inventor: BERG CHARLES ADOLPH
IPC: G02B5/12
Filed: 1981-09-29
Abstract: The invention relates to a reflector arrangement for reflecting incident radiative energy to the source of the radiation. According to the invention, the reflector arrangement has at least two flat reflecting surfaces or facets whose planes intersect at an angle and which are mounted such that the angle between adjacent facets can be adjusted. The facets are driven to make in-phase vibrations, the angle between the facets changing between  PI /2 and  PI /2- delta (rad). In this case, the angle  delta  is selected such that the plane of the maximum surface density of the reflected radiation passes the plane of the source. In this way, the scattering or dispersion effects which arise in known reflectors are compensated in the reflector arrangement according to the invention.

Abstract: The polarity reversing switch contains four stationary contact parts (10, 11, 12, 13), mounted on a base part (1), having curved contact sections (10a, 11a, 12a, 13a), which are arranged at a distance from one another in the rotation direction and together form a circular wall provided with an interruption, a rotatable body (16), which is constructed cylindrically, is fitted into this circular wall and contains two sprung, movable contact parts (21, 22) whose contact ends (21a, 21b; 22a, 22b) can be brought into sliding contact with in each case two curved contact sections adjacent to the four, on rotation of the rotatable body. The rotatable body can be pivoted over a pivoting region of 90 DEG  between a first position, in which each movable contact part produces an electrical connection between two adjacent stationary contact sections, and a second position, in which in each case the other adjacent stationary contact parts are electrically connected to one another. It carries an eccentric pin (20) which extends through a curved slot (24) into a cover which is mounted on the base part, and can be operated by means of an operating lever (29) which is fitted on the cover such that it can pivot. A cap (14) is pressed into positioning openings in the cover by the pretensioning of a spring (15), in order to determine the switch positions. The stationary and movable contact parts are in sliding contact with one another, and fusing in use is hence prevented. <IMAGE>

Title: Roller blind for windows and doors on buildings
Inventor: SCHMITZ ULRICH DIPL ING
IPC: E06B9/165
Filed: 1982-07-24
Abstract: The essence of the invention concerns a roller blind for windows and doors on buildings, which   - prevents the high heat losses through the window area, in particular in winter; - permits generally greater incidence of light through the viewing slit webs, without impairing the known screening from outside to inside.   Closed roller blinds can have the effect of saving heating energy by stilling the air in front of the window glass. If on the outside in front of the tightly closing window, the heat-insulating properties of a roller blind and of a layer of air cannot be used. According to the invention, their use is made possible by the roller blind 3 in Fig 1 being able to be raised into the roller blind housing 1 and by a slide 26 in the bottom of the roller blind housing 1 also being able to be inserted into inner guide rails 7. The viewing slit webs 10 in Fig 5 have a greater height and a greater perforation than conventional viewing slit webs. The light incidence is considerably increased as a result. However, horizontal viewing through the roller blind slats is restricted by the oblique and complementary profiling of the upper and lower edges of the slats with respect to the significantly smaller viewing slit widths 38. <IMAGE>

Filed: 1982-10-27
Abstract: An apparatus is disclosed for the determination of the actual mixing ratio of a non-stoichiometric fuel/air mixture supplied to a combustion device, e.g. to an automotive internal combustion engine. The apparatus has an oxygen-sensitive element with a gas-impermeable solid electrolyte layer which conducts oxygen ions, and first and second electrode layers placed on this, a first gas diffusion layer closely covering the first electrode layer with a relatively low resistance to the passage of gas, and a second gas diffusion layer closely covering the second electrode layer with relatively high resistance to the passage of gas. A catalytic metal, e.g. platinum, is used as the material for at least the first of the two electrode layers. The element is arranged in the exhaust gas given off by the combustion device, and a constant direct current is caused to flow in the solid electrolyte layer from a predetermined one of the two electrode layers to the other. The output voltage is proportional to the mixing ratio within a specific range deviating upward or downward from a stoichiometric ratio and depending on the direction of the current flow in the solid electrolyte layer.
