Title: Circuit for converter (inverter), especially pulse-controlled inverter
Inventor: JUNGE GUENTER DIPL ING
IPC: H03K17/0814
Filed: 1988-02-11
Abstract: The invention relates to an additional circuit for converters, especially pulse-controlled inverters, having pairs of branches, in which a freewheel diode connected in antiparallel and an RCD network, controlled by an auxiliary switch and acting as a low-loss load-rejecting circuit, are assigned to each branch switch. In order not to detrimentally affect the functioning of the low-loss load-rejecting circuit, it is proposed according to the invention that one clamping circuit (K) having a high-capacitance additional capacitor (CK) be provided per branch pair as an additional RC circuit. The additional capacitor (CK) is connected in parallel with the D.C. source (6) and furthermore has its terminals crossed over via blocking diodes (DK1 and DK2) to the central divider points (11, 12) of the two controlled RCD networks. Effective voltage limitation for the semiconductor branch switches is thereby achieved in the case of pulse-controlled inverter circuits affected by induction. Semiconductor switches having low reverse values can be used, which are less expensive and smaller and cause less power loss. <IMAGE>

Patent DE-3808912-A1 (DE)
Title: Sliding bearing bush
Inventor: HUNGER WALTER
IPC: F16C33/28
Filed: 1988-03-17
Abstract: The invention relates to a sliding bearing bush with a metallic support, the sliding surfaces of which have a metallic netting coated with PTFE. The invention starts from the realisation that a considerable proportion of the wear is due to impurities which penetrate continuously from the outside inwards between the bearing pin and the sliding surface and that a large proportion of bearing bushes are subjected to shock loads which, in the case of high-strength inflexible materials, lead to deformation or destruction, and, to reduce the wear and hence increase the life of the bearing, the invention provides that the metallic support have, on its two outer ends, seal stripper elements made of plastic, e.g. elastomers, which are arranged in corresponding grooves and are seated firmly on the bearing pin, and that the coated netting be arranged between the seal stripper elements and be connected to the metallic support by a high-strength intermediate strip made of plastic.

Title: Device for scraping printing ink on screened rollers on printing machines
Inventor: APITZ JOACHIM
IPC: B41F31/04
Filed: 1988-07-01
Abstract: The invention relates to a device for scraping printing ink on screened rollers on printing machines. Previously, frame oscillations were transmitted directly onto the doctor, which oscillations could indeed be suppressed to the greatest extent by an increased pressing-on pressure of the doctor onto such a roller, but, in doing so, a relatively great wear occurred both on the doctor and on the roller. In the doctor device according to the invention, the working plane, which at the same time is the working plane of the doctor, is separate from its drive plane forming a functional unit with the machine frame. The doctor device is arranged in this way in that the doctor attached in the working plane is functionally connected, via damping members, to its drive shaft located in the drive plane, the main oscillation direction of the doctor being at such an angle to its direction of relative movement to the screened roller that both movements do not lie in the same direction. The service lives of the ink transfer rollers are thus extended considerably, that is to say the intended ink metering is kept constant for a longer time. <IMAGE>

Title: Door, shutter (flap) or the like for openings of shielded rooms
Inventor: SPOTH ADOLF
IPC: E06B7/23
Filed: 1988-07-26
Abstract: In case of rooms which are shielded against electromagnetic interference fields and have to be accessible via doors or the like, the opening which is closed by the door exhibits a case and a shielding door leaf which is articulated on said case, there being provided a peripheral, electrically conductive connection between door leaf and case which is interrupted when the door is opened and is composed of at least one outwardly open U-profile on the case, of a profile which, in the closed position, penetrates into the open profile, simultaneously forms a frame and is located on the door leaf, and of spring contacts which act between these and are located on the inner sides of the two legs of the U-profile. A simple and functionally reliable construction is obtained in that the profile on the door leaf is an outwardly tapering trapezoidal profile, whose trapezial angle is dimensioned, in relation to the pivoting radius of the door leaf about its articulation, such that the spring contacts are loaded only towards the end of the closure movement.

Patent DE-3901457-A1 (DE)
Inventor: SCHMIDT KARL-HEINZ
IPC: G06F12/14
Filed: 1989-01-19
Abstract: The memory regions 17 of a computer are monitored by a programmable hardware circuit including a RAM 3 which stores permissible accesses associated with different access levels; and the circuit permits memory access only to predetermined regions. If there is an unauthorized access attempt to a memory cell, the program location in the memory initiating the unauthorized access is detected at 14, the respective program is stopped and an alarm 402 is actuated. In this way, procedures for protecting the operating system cannot be circumvented to gain unauthorized access to data. After programming of the RAM 3 is completed, write-in access to it is terminated by a flip-flop 12 and cannot be renewed except by actuation of a switch 13. Removal of the circuit will cause short circuits, thus making it impossible to shut the circuit off without being detected. <IMAGE>
