Abstract: A synchronous adjusting device for a chair is provided where the restoring movement of a back part is effected as a function of the weight of the user, a restoring moment occurring with the increase in inclination of the backrest. For this purpose, the back part is mounted rotatably relative to the seat part at a distance in height. The leaning force of the user at the back leaning point is counteracted by a restoring force in the lower region of the back part as a result of the articulated connection between the seat part and the back part.

Abstract: A synchronous adjusting device is proposed as a chair mechanism for office chairs, seat furniture or the like, which is constructed extremely simply and with few mechanical components and which, if appropriate, can do without additional force accumulators. At the same time, the restoring movement of the back part will take place as a function of the weight of the user, a restoring moment occurring with the increase in inclination of the backrest. For this, the back part (7) is mounted rotatably relative to the seat part (5) at a distance in height. The leaning force (9) of the user at the back leaning point (10) is counteracted by a restoring force in the lower region of the back part as a result of the articulated connection between the seat part and the back part (7).

Abstract: A device for separating mixtures of liquids not miscible with one another, especially of oil/water mixtures and with a filter medium of a viscose sponge layer which is capable of taking up oil and water is provided. The device is characterized in that, in the direction of flow of the liquid mixture to be separated after at least one viscose sponge layer (3), there is arranged at least one oil repellent viscose cloth (4). The device has the advantage that is allows in simple and certain fashion the separation of oil/water mixtures and an environmentally friendly disposal of the separated oil.

Abstract: An arrangement for supporting a railing provided with a T-shaped groove and a slot communicating with the groove comprises a hollow supporting member and a T-shaped clamping element. The clamping element includes two clamping members each of which members has a first portion insertable in the hollow of the supporting member and a second portion insertable in the T-shaped groove of the railing. The clamping members are movable relative to each other in the longitudinal direction of the supporting member. The first portions of the clamping members are elongated in a direction of elongation of the supporting member, whereas the second portions are formed as pin-shaped projections each having an axis. The pin-shaped second portion of one of the clamping members is offset relative to the pin-shaped second portion of the other clamping member in a direction transverse to the axes thereof and to the elongation of the first portion.

Abstract: An arrangement for supporting a railing and the like has a hollow base member, a hollow bar-shaped member telescopable over the base member, and a clamping element insertable in the base member and spreadable apart so as to spread the base member into clamping engagement with the bar-shaped member. The clamping element has two clamping portions which are partially separated from each other over a plane extending in a direction of elongation of the clamping element and are movable relative to each other in a direction transverse to the direction of elongation. Means are provided for spreading apart the clamping portion, including screws screwable in one of the clamping portions. The clamping portions each has a section outwardly projecting from the base member and adapted to be spread into clamping engagement with the bar-shaped member. The base member and the bar-shaped member have holes provided in walls adjacent to the clamping portion so that the screws may be screwed in the latter through such holes.

Abstract: An apparatus for displaying goods in suspended form includes a fixed carrier support having horizontally and vertically spaced bores, a bearing pin rotatably disposed in each bore and a U-shaped rail bracket extending from said pins with spacer brackets of varying length removably inserted between the legs of said rail bracket.
