Patent DE-3601160-A1 (DE)
Title: Method and device for protection of a converter
Inventor: SKARPETOWSKI GRZEGORZ DR
IPC: H02M7/5387
Filed: 1986-01-17
Abstract: In converters (1, 5) having thyristors (T1...T6) in the bridge arms, semiconductor components can fail as a result of short circuit or interruption, which is monitored and displayed. Fault detection is carried out as a function of the intermediate circuit voltage (UZK) which is detected by means of a DC voltage detector (4) and exhibits one or more successive, time-shifted voltage jumps while a thyristor is being turned on (during triggering of a thyristor). In a signal detection circuit (10) having a differentiating element on the input side, an analog/digital switch having a limit value which can be predetermined is used to monitor whether the voltage drop is greater than the predetermined limit value. If yes (S18 = "1"), an evaluation circuit (11) is subsequently used to monitor whether this 1st voltage drop occurs within a limit value, which can be predetermined, for the thyristor switching-on delay of 60  mu s. If no, a fault signal (F1...F6) is produced, which can be used for a fault display and/or for recording. The evaluation circuit (11) can also be used to monitor the conduction durations of the thyristors (T1...T6). Equivalent triggering pulses (turn-on pulses) for other thyristors and/or a blocking signal (S54) for thyristor triggering pulses (T1>>...T6<<) can be produced as a function of the thyristor conduction duration exceeding a limit value. <IMAGE>

Title: Device for the active damping of a driver's seat or of a hospital bed or of a fragile load
IPC: A61G3/00
Filed: 1986-03-14
Abstract: In order to permit the person or the fragile load to be isolated from the state of the road or from the travel gear, a device is proposed which relieves the body of the person with the aid of an active damping system in the immediate vicinity of the car seat or hospital bed. The person no longer has to be subordinated to the requirements of the vehicle but can individually determine the kind of suspension which is pleasant for him. Sensors perceive unevennesses on the road and pass them along to the entire system. In conjunction with a process computer unit, the said system ensures, in the form of an enclosed operation sequence, that the pulses acting on the human body are minimised in accordance with the prescribed limits. A considerable relief of the spinal column is thus achieved and resulting injury is prevented. <IMAGE>

As the movable member, which is constructed of a ferromagnetic material, nears the switch housing, the air gap between the second contact and second pole is bridged and the contacts close indicating the proximity of the movable member to the switch element. The entire proximity switch apparatus can be moved along the longitudinal axis of the cylinder.
Patent DE-3613173-A1 (DE)
Title: Shop counter
Inventor: SCHINDLER RUDOLF
IPC: A47F3/04
Filed: 1986-04-18
Abstract: The invention relates to a shop counter with a main plane which contains a working area and a main display area and below which a circulating-air cooling device is arranged, and with an air passage opening in the main plane. In known shop counters, in particular when they are used for the display of bread or baked products, crumbs or other impurities fall through the passage opening into the interior of the shop counter, thus entailing daily additional cleaning work. According to the invention, provision is therefore made for there to be arranged below the air passage opening a crumb-collecting area which, in plan view, covers the passage opening from below, but leaves open a lateral air passage. Crumbs and other impurities are collected in the crumb-collecting area and can be simply removed during cleaning, without previously soiling the interior of the shop counter. Nevertheless, the crumb-collecting area does not impair the circulating-air cooling.
Patent DE-3614005-A1 (DE)
Inventor: RICKERT HANS PROF DR
IPC: B01D53/34
Filed: 1986-04-25
Abstract: A process for desulfurizing waste gas is described, wherein an SO2 containing waste gas is absorbed in an aqueous solution and the resultant solution containing sulfite is treated electrolytically which is much less expensive than the prior art methods, is simpler to implement and avoids the danger of producing explosive gases which is possible in prior art methods based on anodic O2 formation and cathodic H2 formation. In this process, electrochemical oxidation of SO32- ions into SO42- ions occurs at the anode as well as a simultaneous formation of H+ ions, thereby producing H2SO4, while avoiding the production of oxygen. Apparatus suitable for carrying out this process is also described.

Title: Method for limiting or interrupting the current of a drive device on reaching or exceeding an upper limiting current value, and a protection circuit for carrying out the method
Inventor: KRAMER HORST W M
IPC: H02H3/00
Filed: 1986-10-11
Abstract: In order to limit or interrupt the current supplied to a drive device having at least one electric motor on reaching or exceeding an upper limiting current value, a variable which represents the actual value of the current is compared with a variable which represents the upper limiting current value. As soon as the magnitude of the actual value reaches or exceeds the magnitude of the limiting value, a switching process is initiated which influences the current. The magnitude of the limiting value is continuously determined on the basis of the magnitude of the actual value plus a magnitude to maintain a separation from the actual value magnitude, the permissible change and/or the rate of change of the limiting value magnitude determined in this way being kept smaller, at least in one direction, than the corresponding change and/or rate of change of the actual value magnitude. <IMAGE>
