Patent DE-3835706-A1 (DE)
Title: Hot runner system for the injection moulding of thermally sensitive polymers
Inventor: BATRA RAMESH
IPC: B29C45/27
Filed: 1988-10-17
Abstract: The hot runner system for thermally sensitive polymers not only ensures that the heat supply is switched off if there is an interruption during processing, but also initiates the cooling operation, so that the polymer melt remaining in the hot runner system can no longer decompose due to heat contained in the system. For this purpose, the heat transfer medium is converted into heat removal medium and once again used as a heat transfer medium when starting up again after the fault has been rectified.

Title: Service station fuel pump - is automatically switched off when vehicle fuel tank is full
Inventor: HEIN JOERG
IPC: B67D7/48
Filed: 1989-12-01
Abstract: Fuel from a service station storage tank (7) is delivered to the fuel tank of a motor vehicle through a filler gun (3).  The interior of the gun is connected by a flexible pipe (9) to a suction pump (1) which produces a sub-atmos. pressure in the interior of the gun.

Title: Arrangement for locating focus point of parabolic reflector - samples reflector surface for dimensional accuracy
Inventor: WELLHAUSEN HEINZ PROF DIPL ING
IPC: G01M11/00
Filed: 1990-02-16
Abstract: A correctly placed microwave source (3) will radiate a perfectly parallel beam from all the parts of a parabolic reflector (1). In the manufacture of such reflectors, there is the problem of how to execute quality control., e.g. how to measure any deviation fromthe perfect, parabolic form.  When a strong, point like light source is placed into the focus (3) of the antenna reflector and an arrangement of two parallel plates (4,6) having identical patterns of holes in them is placed at some distance in front of the reflector, sharp images of the holes will appear on a projection plane (5). The images can be seen by a human or electronic eye (7). If the borders of a hole image are fuzzy or partially obscured this points to a location of low dimensional quality on the reflector. ADVANTAGE - Efficient.

On the other side, symmetrically with this, also at a distance y from the longitudinal centre plane, a hydraulic cylinder 19 or shock absorber 19' is also hinged at 5'. At the other end the two cylinders 2, 19 or shock absorbers 2', 19' are hinge-connected to 4 on the slewing ring outer section 1' in a vertical plane on the longitudinal centre plane. With the cylinders or shock absorbers in this position the articulated set is in straight- line running. The distance of the articulation points 5, 5' from the articulation point 4 in the longitudinal centre plane is designated by x, the inner dead centre position of the hydraulic cylinders or shock absorbers by bmin, the radius of the slewing ring by a, the bending angle between front coach 3 and follower 6 by angle  beta . Angle  gamma  is the angle formed by the straight line from point 5 or 5' to the centre point of the slewing ring and the  longitudinal centre plane. If the follower 6 now bends to the left, the hydraulic cylinder 2 or shock absorber 2' and hydraulic cylinder 19 or shock absorber 19' are shifted to the right, the travel from 2, 2' to the point A being reduced and the travel from 19, 19' to point A being increased by the same amount. At point A the moment of 2, 2' is equal to 0. On the travel beyond A the moments of the cylinders 2, 19 or the shock absorbers 2', 19' are cumulative.

Title: Adjustable ink jet print head - has heating and ink chamber sections shiftable against each other
Inventor: BUEHLER KARL DIPL ING
IPC: B41J2/16
Filed: 1990-05-22
Abstract: When different inks or different colours are to be used for ink jet printing, the ink jet heads must be changed so as to work with the selected ink substance. This circumstance, however, leads to increased costs and longer delivery times. The invention deals with a mechanical solution, the print head consists of two parts:- a resistive layer on a substrate (2,3,4) which heats an ink jet cell, and an aggregate of small ink channels (11,12,113,14) from which the ink jet emerges. - Normally, each heater element is right opposite its corresponding jet channel. By making the two parts adjustable against each other, the effect of a heater element on the heating process in the jet cell is modified. It has turned out that one and the same ink jet head can thus be used for a variety of inks and colours.
