Abstract: A coupling arrangement for towing conveyors comprising a towing chain having catchers, a track disposed below the towing chain, running carts equipped with two running mechanisms rolling on the track, said catchers having movable coupling parts and said running carts having coupling elements securely disposed on said running mechanisms cooperating with said coupling parts, where the coupling parts disposed on the catchers of the towing chain comprise a housing in which a catcher finger and a setting lever which is in operative relationship thereto are pivotally mounted for movement in opposite directions about horizontal axes in a manner that the setting lever normally holds the catcher finger in its position of engagement and for a raised position of a run up part provided at the rear running mechanism of each running cart with a local running mechanism as seen in the direction of feed causes a pivoting upwardly of the catcher finger, while the roller carriers' supports of the running cart are designed as co

Abstract: An electric blanket assembly having a blanket whose heating elements are supplied from a low voltage supply source and a control circuit assembly adapted both to regulate the heating of the blanket and to disconnect the supply source from the heating elements under conditions of malfunction of the assembly. The control circuit includes temperature sensitive elements suitably located in the blanket and associated circuitry arranged to generate a control voltage which is selectable and reference voltage generating means which is also selectable. The control circuit also includes means to compare the control voltage and the reference voltage and to control current flow through the heating elements.

Abstract: Exhaust system especially for motor vehicles of the type having a monolith of ceramic material serving as a catalyst support disposed in a metallic housing, said monolith being supported only radially in a double walled mantle having an inner wall of thin foil-like material closely encompassing the monolith and an outer wall defining the sole support connected at the ends in seal-like fashion and the inner space of which is filled with gas under pressure.

Abstract: Aim control arrangement for conveyor installations of the type having coding cards coordinated to individual carriages that work together with address questioning stations of the conveyor installation comprising a chain guiding rail, a running rail for said carriages, a pulling chain guided by said chain guiding rail, an address carrier frame for each carriage in which the coding card is received, an adjusting insert in said frame operative to adjust the height of the coding card in the proximity of the address questioning stations for cooperation with corresponding means.

Abstract: Dispenser for a bottle top with a cylinder and a plunger that is adjustable relative to the cylinder for drawing up an adjustable quantity of liquid esp. reagent with a suction valve and a discharge valve and having a glass cylinder secured to a valve block which is threadedly received on a reagent bottle and where a cylinder sleeve slidably and rotably extends over the glass cylinder and is connected with the plunger which slides in the glass cylinder and where means are provided for adjusting the stroke of the plunger and to indicate the suction volume.

Abstract: Arrangement for producing piped openings in cut blanks of garments, comprising a displaceable supporting plate and a folding device including a folding slide for piping strips defined by movable folding tools and a working blank clamp displaceable relative to the needles of a double needle sewing machine having a separating cutter working centrally between the needles and adapted to be lowered upon the cut blank, two folding and clamping rails defining a folding shaft between them supported for vertical movement and pivotally supported at their upper ends for rocking movement toward and away from one another and relative to said folding slide, means for raising and lowering said folding and clamping rails together by an adjustable distance relative to a cut blank in said folding shaft.
