Patent DE-3807691-A1 (DE)
Title: Homopolar ferromagnetic power machine
IPC: H02K53/00
Filed: 1988-03-09
Abstract: The invention provides a machine which converts ferromagnetic energy into mechanical energy and is thereby capable of doing work. The energy conversion here relies only on the property of ferromagnets that they repel like magnetic poles in their vicinity and therefore exert mechanical force which is then, by application of the lever principle, converted into rotational movement of the rotor. Seven ferromagnets are arranged in a housing at right angles to the mid-point of the system, offset at right angles in the direction of rotation, so that their like magnetic poles follow one another in the direction of rotation. In addition, a ferromagnetic rotor is rotationally mounted at the mid-point of the system and its two rotor magnets are arranged in the soft-iron rotor magnet holder so that the like magnetic poles of the stator and rotor lie directly facing each other and, as a result, the mechanical force of the homopolar ferromagnetic force field produced between the stator and rotor, acting as a lever, continuously moves the rotor in one direction of rotation. The resulting torque of the rotor enables the machine to do work.

Patent DE-3812357-A1 (DE)
Title: Sliding valve for foundry equipment
Inventor: EGEA MARCOS RICARDO LUIS
IPC: F16K3/06
Filed: 1988-04-11
Abstract: The invention relates to a sliding valve which can be used in casting ladles and other vessels used in metal foundries and, as one of its features, has the fact that the movable refractory plate is constructed so that it can be displaced in opposite directions starting from the open position of the valve, in which the hole in the plate coincides axially with the hole in the fixed refractory plate, with the result that the erosion caused by the molten metal during the opening and closing operations alternately affects one edge region and the other, opposite edge region of the hole, thereby considerably lengthening the useful life of the plates. Another feature is that the fixed baseplate to which the likewise fixed refractory plate is attached, is connected to the carrier plate on which the movable refractory plate is mounted by means of spring-loaded catches situated in the edge region, these edge regions being arranged sufficiently far from the pouring hole for the molten metal, i.e. these spring-loaded catches are located well away from the source of heat and are furthermore provided with a cooling system, the nozzles of which point towards the spring-loaded latches.   <IMAGE>
Patent DE-3812697-A1 (DE)
Inventor: PROFOS PAUL PROF DR ING
IPC: F23N1/02
Filed: 1988-04-16
Abstract: In order considerably to improve the combustion during the operating time of smaller ventilator burners also, in particular one or two-stage ventilator burners, with reasonable outlay, as the main deregulating factors the pressure (pL) and temperature ( theta L) of the combustion air are measured and from these, on a compensator (25), a simple compensation function is determined, with which, on a superposition unit (27), action is taken on the combustion air flow (L<*>) and/or on the fuel flow (B<*>). Precisely in said burners, the greater part by far of the influence of deregulating factors stems from said main deregulating factors.

Title: Ink jet printer and method of protecting the ink of an ink jet printer against drying up
Inventor: BERNARDI HERBERT
IPC: B41J2/165
Filed: 1988-07-18
Abstract: In an ink jet printer, in order to prevent the drying up of the ink during standstill times and consequently the clogging of the ink jet nozzle, a given quantity of a filling liquid (e.g. silicone oil) is, before standstill times, introduced into the region in front of the nozzle opening. On the start of the following printing process, the filling liquid is again removed from the region of the nozzle opening. The filling liquid prevents ambient air reaching ink in the region of the nozzle or of the ink supply line. The filling liquid does not mix with the ink and is preferably non-volatile. Thus, a clogging of the nozzle by drying up of the ink is prevented even in the case of inks with a highly volatile solution.

Title: Cubic boron nitride grinding wheel - has layer of CBN abrasive electroplated onto flanks on teeth on periphery of grinding disk
Inventor: TAWAKOLI TAGHI
IPC: B24D7/06
Filed: 1989-11-08
Abstract: The circumference of the grinding wheel disc has rectangular profile teeth (2,3,4...), the flanks of which have an electroplated layer of cubic boron nitride (CBN) abrasive.  Other tooth profiles have advantages for specific applications. Unlike conventional CNB grinding wheels, the wheel can easily be trued on the machine spindle without a substantial loss of abrasive. The kinematics of the grinding process ensure that only the abrasive outer edges of the teeth (25-30) are in contact with the work. ADVANTAGE - Grinding force is reduced.  Coolant and grinding debris can flow out of spaces between teeth.  Grinding quality is maintained irrespective of wheel wear.  Special wheel tolerances are not necessary since the wheel can easily be trued.
