Title: Mirror for platen of office machine - concentrates external light on paper inserted in machine, avoiding direct illumination
Inventor: ANKER FRANZ
IPC: B41J29/18
Filed: 1980-04-21
Abstract: The reflection platen mirror is inserted on the casing of computer or typewriter for illumination of the paper inserted into the machine and clamped on the platen. The illumination takes place by reflection of impinging light, e.g. of external daylight, or from another external light source. The mirror is pref. held on the machine casing, or a securing disc by a magnet in a plastics housing. In this manner the vibrations of the machine cannot cause the mirror turning or shifting. On the other hand the mirror can be set down in any random position, or removed when not needed. The mirror support cannot cause the mirror turning or shifting. On the other hand the mirror can be set down in any random position, or removed when not needed. The mirror support may be firmly adhered to the plastics housing and to the mirror disc. The support may have a ball joint capable of rotation and tilting to provide the best reflective position.

Patent DE-3021999-A1 (DE)
Inventor: GASSER RENE
IPC: D06F39/02
Filed: 1980-06-12
Abstract: The device has a central cylindrical container (1), into which two inflow connections (2, 3) open in the radial direction. Arranged diametrically relative to these inflow connections are two first outflow orifices (4, 5), and between these is located a third outflow orifice (7). A water jet from one inflow connection (2, 3) or the other passes by way of the free zone within the central container (1) to the opposite outlet orifice (4, 5). If water flows simultaneously through the two inflow connections, most of the jet passes into the third outlet orifice (7). When washing agent is being introduced into an automatic washing machine, this device makes it possible, with only two water valves and without any other movable parts, to introduce the washing agent, the main washing agent and finally a finisher. The free path in the container (1) prevents a return flow. <IMAGE>

Title: Differential pressure display device for air filters
Inventor: LENZEN DITRICH DIPL ING
IPC: F02M35/09
Filed: 1981-03-03
Abstract: A diaphragm (1) is used for the purpose of the optical display of the level of pollution of a filter element of air filters for internal-combustion engines, in particular. Said diaphragm is exposed on one side to the underpressure on the clean side of the filter element, and on the other side to the atmospheric pressure. It has an initial rest position, into which it returns as far as a specific, prescribable differential pressure limit value in the event of no flow through the filter element, and an oppositely directed final rest position into which it snaps in the event of overshooting of the limit value. In its initial rest position, the diaphragm (1) bears against a transparent wall (3), which can be a diverging lens, in the form of a marking (6) visible from outside. When the diaphragm (1) has snapped over into the final rest position, the marking (6) is no longer visible, i.e. the filter element is impermissibly polluted. <IMAGE>
Patent DE-3108276-A1 (DE)
Title: Gripping or clamping tool
Inventor: KLIMACH HORST ING GRAD
IPC: B25B7/10
Filed: 1981-03-05
Abstract: The invention relates to a gripping or clamping tool with two lever handles which can be pivoted relative to one another and are each provided with a gripper jaw. One lever handle is formed in one piece with the gripper jaw allocated to it, while the other gripper jaw is arranged on the other lever handle in such a way that it can be displaced, tilted or locked. To open the gripper head, the one gripper jaw is therefore to be displaced accordingly, whereas to clamp a workpiece only the one lever handle is to be pivoted slightly, as a result of which the displaceable gripper jaw is secured to the other lever handle, for example by tilting, and forms an abutment. This gripping or clamping tool permits a large gripping capacity, a symmetrical engagement of the gripper jaws on the periphery of a pipe or suchlike workpiece, and continuously adjustable adaptation, which is easy to carry out, of the width of the gripper head to the corresponding outside dimensions of a workpiece. <IMAGE>
