摘要:
Hydrophobic textile materials exhibit reduced tendency to static charge buildup, significantly improved absorbency and reduced soiling tendency when treated with a water-dispersible polyester having structural units of the formula ##STR1## wherein A is, on statistical average, 80 to 100 mol percent of p-phenylene and 0 to 20 mol percent of divalent moieties of the formula ##STR2## and wherein G is, on statistical average, 30 to 90 mol percent of linear or branched divalent alkane moieties having 3 to 6 carbon atoms which may be interrupted by 1 or 2 oxygen atoms, 10 to 30 mol percent of divalent polyether moieties having an average molecular weight of 1,000 to 3,000, and up to 50 mol percent of ethylene moieties, and R is a straight-chain or branched alkyl or alkenyl having 6 to 8 carbon atoms.
摘要:
A carrying device for busbars, having at least one holding device to be fixed on a base unit. The device has a receiving opening for feeding through at least one busbar, and a clamping device for fixing the same. Expanded installation possibilities of busbars result if there is a receiving part that is inserted, or that can be inserted, in the receiving opening. The part can have at least one recess that is adjusted to the cross-section of a busbar, and the respective busbar can be selectively disposed in the holding device in at least two installation positions pivoted about the longitudinal axes thereof, by the receiving part.
摘要:
A device adapter including a base part, the bottom side of which has busbar fixtures to be mounted on and contacted with busbars while the top side thereof supports a mounting device that is removably fixed and has two parallel spaced-apart longitudinal rails for coupling electric devices or house wiring units. In order to keep the design simple while offering variable mounting possibilities, the connecting device includes protruding, hook-type hanging elements which are molded onto the bottom side of the longitudinal rails, which can be vertically inserted into receiving holes that are adjusted thereto and are located on the top side of the base part, and which can be hung on the side of the receiving holes facing away from the top side in the area behind the receiving holes by performing a movement in the longitudinal direction. A releasable locking element can lock the hung position of the longitudinal rails.
摘要:
A bus bar system having several bus bars spaced apart from each other in a first connecting plane and of an essentially square cross section and having T-shaped connecting grooves cut into all outsides for a connection with electrical installation devices having flat connectors in a second connecting plane, which is arranged perpendicular to the first connecting plane. With specially embodied connecting and insulating elements, it is possible to displace the connecting planes of the bus bars and of the flat connectors of the installations device parallel and perpendicular with respect to each other without it being necessary to perform elaborate matching assembly work at the site.
摘要:
A multi-function adapter with a base housing, on which suspension hooks corresponding to the number of bus bars of a bus bar system are formed, which are offset with respect to each other in the longitudinal direction of the base housing in a manner corresponding to the spacing of the bus bars, and which are accessible through contact rail receptacles for the insertion of connecting contacts, which connect the inserted contact rails with the bus bars. A multiple variation of the adapter is achieved because the narrow side walls, the long lateral walls and the top of the base housing have snap-in receptacles with snap-in shoulders, by which narrow side cover elements, top cover elements, perforated strips and equipment connection elements can be selectively connected with the base housing with appropriately designed and distributed snap-in springs.
摘要:
An assembly kit for a busbar system made of holders and of busbar sections that can be fixed in position or are fixed in position in receptacles of the holders, which receptacles are spaced from and parallel to one another. An extension of the busbar system in two directions running perpendicularly to one another while completely covering the busbar sections on the side facing the mounting surface is achieved by an assembly kit of the following elements:(a) holders of a first type composed of rectangular carrier plates with their longitudinal dimensions aligned in the longitudinal direction of busbar sections which are fixed in position in receptacles in their tops and which terminate flush with their narrow sides;(b) holders of a second type consisting of right-angled carrier plates in which right-angled busbar sections are fixed in position in receptacles thereof that terminate flush with the end faces thereof, the end faces being located perpendicularly to the busbar sections; and(c) connecting elements with which abutting ends of busbar sections can be connected to one another so as to conduct electrically in the area of the joints of the carrier places constituting the holders of the first type and/or of the second type connected together in a row.

摘要:
A connection or device adapter, which can be placed on a mounting unit at right angles with respect to a longitudinal direction of busbars and mechanically connected, one contact element being electrically conductively connected to the facing busbar in a connection or device adapter per busbar and the contact elements in the connection or device adapter being led up to connection receptacles in the region of a narrow side of the connection or device adapter. If the contact elements are formed as contact bars and are electrically conductively connected to one another by the associated connection receptacles and form connection units and for the connection or device adapter to have receptacles for the connection units in the region of a narrow side and to accommodate the contact elements with contact points positioned in relation to the busbars, the complexity in terms of parts and assembly, in particular for the connection or device adapter, is substantially reduced and simplified.
