Title: Cleansing module
Inventor: FRENER KARL DIPL ING
IPC: H05K3/00
Filed: 1987-03-16
Abstract: The invention relates to a cleansing module for horizontally running, perforated printed circuit board blanks 2 which are guided by transportation rollers arranged on both sides, in the case of which cleansing module, a slotted nozzle is arranged underneath the printed circuit board blank 2. After the drilling process, the walls of the drilled holes of printed circuit boards are covered with drilling residue (swarf), such as epoxy resin or glass. It is thus initially necessary to carry out coarse mechanical cleaning of the drilling residues of the whole walls before the subsequent chemical fine cleaning. For this purpose, the invention provides that the slotted nozzle 1 is arranged on a linkage 3 such that it can move transversely with respect to the printed circuit board movement direction and that a cleansing means is forced through the slotted nozzle 1 at high pressure, for example at 30 bar. <IMAGE>

Patent DE-3716263-A1 (DE)
Title: Decubitus-preventing substrate
Inventor: ZAHORANSKY EDGAR DIPL ING
IPC: A47C27/08
Filed: 1987-05-15
Abstract: A decubitus-preventing mat comprises a multitude of individual cells (1 to 7) which are provided with heating elements (10) for selectively converting a liquid (11) in the different cells (1 to 7) from the liquid into the gaseous state in order thus to generate a superatmospheric pressure in selected cells (1 to 7), so that the surface supporting the body of the patient can be temporally varied. Due to the electrical control of the heating process and the change in volume associated therewith the supply of gaseous or liquid media from the outside can be dispensed with, so that noise nuisance due to pumps or compressors can be avoided. Further advantages of the absence of pumps and compressors are less susceptibility to faults requiring repair and reduced maintenance costs, lighter weight, easier transportation and simpler handling. <IMAGE>

Title: Headlamp and light unit for motor vehicles
Inventor: GOOS BERNHARD
IPC: B60Q1/00
Filed: 1987-08-12
Abstract: The headlamp and light unit has a frame which bears the headlamp and the flashing indicator light and is attached in an opening in the body of the vehicle. The flashing indicator light can be inserted into the body of the vehicle to the side of the headlamp into locking plug-in connections. The locking plug-in connections are located at least vertically one on top of the other. Each plug-in connection consists of two spring arms which are located in a horizontal plane and whose sides which face away from one another have tooth-shaped catches which interact with locking marks of the sleeve-shaped attachment part. The catches and the locking marks are shaped in such a way that the flashing indicator light can be pushed in in a ratchet-like manner in the insertion and withdrawal directions and can be rotated in the catches by a predetermined distance about a vertical axis of rotation. As a result, it is possible for the cover of the flashing indicator light to be matched in terms of its external contour to the external contour of the lens of the headlight and the body of the vehicle in an optimum way. By means of a third attachment point, the flashing indicator light is connected to the frame in a very stable fashion.
