Patent DE-3902334-A1 (DE)
Title: Bed having a horizontal element which is adjustable, at least with regard to its inclination
Inventor: DEWERT ECKHART
IPC: A47C19/04
Filed: 1989-01-27
Abstract: The bed according to the invention is to be designed in such a way that the space requirement is not increased even in an inclined position of the horizontal part, that the get-in height is comparatively low and that the adjustment path is correspondingly large for adjustment into a height suitable for nursing purposes. In the bed according to the invention the horizontal element is placed on a flat support part which can be adjusted by a lifting device which can exclusively be displaced in the vertical direction, so that the support frame can be pivoted at least about a horizontal axis. In order to permit this pivoting movement the support frame is provided with a device for balancing out the length. The bed according to the invention is particularly suitable as a nursing bed. Its special advantage results from the fact that it can be combined with a conventional bed and that its appearance does not differ from the latter. <IMAGE>

Title: Lubrication of an internal combustion engine for motor vehicles etc. and an internal combustion engine for motor vehicles etc. with a system for engine lubrication
IPC: F01M11/04
Filed: 1989-03-03
Abstract: The invention relates to the lubrication of an internal combustion engine for motor vehicles etc. and an internal combustion engine for motor vehicles etc. with a system for engine lubrication which has an oil tank and an oil feed line, equipped with a metering pump, leading to the engine or the engine sump. In order to guarantee engine lubrication with little pollution to the environment, the invention proposes that the lubricant used should be an environmentally compatible oil, i.e. one which may have little resistance to ageing, e.g. one without additives, that fresh oil should be fed repeatedly to the lubricating-oil reserve of the engine during operation and that at least partially aged oil should be removed repeatedly from the lubricating-oil reserve of the engine and, preferably in a metered manner, added to the engine fuel for combustion. For this purpose, the engine or engine sump is connected via a connecting line fitted with another metering pump to the fuel tank of the engine or to the fuel line between the fuel tank and the engine.

Title: Multi-compartment magazine record player
IPC: G11B17/30
Filed: 1989-04-28
Abstract: A multi-compartment magazine record player includes a row of magazines which are removably stored therein and in each case hold a multiplicity of phonographic records, a playback means, which can be moved successively into alignment with one of the magazines and can be set for playing a selected record contained in the magazine.

Patent DE-3925567-A1 (DE)
Inventor: BINDER ROLF DIPL ING
IPC: B23Q3/155
Filed: 1989-08-02
Abstract: The automatic tool changer for a machining centre is essentially distinguished by the fact that the tool changer can be moved as a unit in the horizontal and vertical direction, that a supporting arm arranged at the end of the vertical arm can be pivoted horizontally, that a gripper arm attached to the supporting arm is rotatable in the vertical direction, and that the gripper arm has two pincers attached at 180 DEG  apart and having two pincer arms each which can be displaced in parallel and are designed both for tools and auxiliary machining heads. 
<??>The advantages obtained essentially consist in the fact that, with the novel tool changer, auxiliary machining heads and tools of different steep-angle taper and flange diameter can be changed between the magazines and the spindles preferably of machining centres with vertically and horizontally arranged spindles. The most varied range of diameters can be handled due to the displaceability of the pincer arms. On account of the considerable mobility of the tool changer, tools can be exchanged in the horizontal, vertical and sloping position of the spindle of the machining centres.

Patent DE-4014070-A1 (DE)
Title: Mfg. process for printed circuit boards - forming by injection moulding with trenches filled in with conductive material for tracks
Inventor: MASSOTT PHILIPP
IPC: H05K1/09
Filed: 1990-05-02
Abstract: The tracks are formed in trenches formed in the board on molding which are filled in with a conductive  material. Thus tracks for heavier currents are not wider than those for lighter currents but have a greater cross section by being deeper which allows for a greature surface density of tracks on the board, and, since the tracks are embedded into the board they are more protected from mechanical damage. The contact pins are held firmly, but removably in the board. The manufacturing process can be computer  controlled. USE/ADVANTAGE - Enviromentally friendly, no toxic emissions during manufacture. Suitable for mass  production. No soldering needed. Precise control possible.  Less chance of damage to tracks. Greater density of tracks possible.
