  • Publication number: 20190186523
    Abstract: To fasten a first component to a second component, a fastening clip has an integral, elongated structure with a first and a second fastening end. The first fastening end comprises an at least one-armed independent latching structure. The second fastening end is formed by a resilient clamp. The first and second latching structure act on an intermediate support structure. To connect the two components, the latching structure is latched in a component opening in a first component, and the second component is fastened between the support structure and a spring loop of the resilient clamp with the assistance of a cutout or a slot that is open on one side.

  • Patent number: 4775006
    Abstract: A heat exchanger, particularly a coolant evaporator, is provided that has several flat pipes that are arranged parallel to one another and are each expanded at their ends with respect to a central part and are closed off by caps. The expanded ends are provided with connecting openings so that the heat exchange medium can flow to the adjacent pipe. At least one of the caps that are provided for closing off the pipe ends is equipped with a projection extending towards the inside of the pipe and closes off at least one of the connecting openings, so that the production of a heat exchanger of identically constructed flat pipes is simplified, in that by the insertion of correponding caps that either expose the connecting openings to the adjacent pipes or not, it is easy to control the flow of the heat exchange medium inside the flat pipes.

  • Patent number: 4690692
    Abstract: This invention relates to a method for the manufacture of an abrasive material by means of a synthetic binder based on a mixture of phenolic resins. The phenolic resins employed have a great stability in storage, its curing times are at most equal to but preferably shorter than those commonly used, therefore higher production speeds or substantially smaller drying installations for the same production speed may be used. The binder contains only small quantities of free formaldehyde, phenol and especially formaldehyde are released in substantially reduced quantities to the environment even when the binder is heated to elevated temperatures, including temperatures above the processing temperature. The release of these substances is also considerably reduced when the abrasive material is subsequently used.
