Patent DE-3632962-C1 (DE)
Title: Control device for the brake and/or drive of a conveying system
Inventor: TUESCHEN ALFRED
IPC: H02P29/00
Filed: 1986-09-27
Granted: 1988-02-11
Abstract: The invention relates to a control device for the brake and/or drive of a conveying system, in the case of which the conveying means is guided by means of frictional engagement over a roller 1 of the braking device 9 or of the drive. A device 7, 8, 22 for monitoring the speeds of the roller 1 and the conveying means is used to check whether slippage is occurring and/or that a predetermined braking deceleration or acceleration is not being exceeded. The braking force and/or the drive output is/are set by means of a remote-controlled desired value setting device 30. To the extent that slippage is detected and/or the preset threshold value for acceleration and/or braking deceleration is exceeded, the value supplied by the desired value setting device 30 is modified in order to reduce the braking force and/or braking deceleration or starting acceleration. <IMAGE>

Title: Furnace for testing support panels
Inventor: POLACZY ANDREAS
IPC: F27B17/02
Filed: 1987-07-01
Granted: 1988-02-11
Abstract: Furnaces with a furnace chamber for testing test parts arranged on support panels, in particular electrical components arranged on circuit boards, are known, there being provided in a wall, floor or ceiling part one or more slots with, fastened on both sides of the longitudinal sides of the slot, temperature-resistant sealing lips, through which parts of support panels can be pushed. In order to design a furnace of the type described in such a manner that the sealing elements seal the furnace chamber adequately tightly both with support panels inserted and in the unoccupied state, are suitable also for support panels of different thickness and thus for broad slots and guarantee adequate sealing after relatively long use, sealing lips are formed in each case from two tubular sealing profiles in such a manner that the profiles rest flat on one another in the slot centre.

Title: Safety discharge system for accumulators
IPC: F21V23/00
Filed: 1988-08-25
Granted: 1989-12-28
Abstract: The reaching of the discharge cut-off voltage in diving lamps which are powered by accumulators must be indicated to the diver in advance, since without forewarning that the discharge cut-off voltage is being reached and without extension of the residual operating time of the accumulator, the diver may possibly have to surface in darkness or become lost in a cave. In order for the reaching of the discharge cut-off voltage of an accumulator to be indicated in advance, and in order for it to be possible to extend the residual operating period then remaining, the load is periodically switched off and on when an accumulator voltage is reached which is somewhat higher than the discharge cut-off voltage. Since the frequency is in excess of 25 Hz, the impression is given - if the load is an incandescent lamp - not of flashing, but rather the impression of a softly glowing incandescent bulb. When the discharge cut-off voltage is reached, the load is now additionally switched off periodically for a longer period of time. Again, if the load is an incandescent lamp, the clear impression of flashing then results. The advantages achieved with the invention are warning beforehand of impending reaching of the discharge cut-off voltage and the extended operating period and the repeated switching of the load with recovery of the accumulator. Diving can therefore be made more safe in the case of cave diving and night diving.

Title: Signal level and frequency monitoring for telephone call tone circuit - feeding frequency information for call tone input signal to microprocessor via DC voltage converter providing galvanic separation
Inventor: NIJMOLEN GERRIT WILLEM
IPC: H04B3/46
Filed: 1992-04-29
Granted: 1993-10-21
Abstract: The monitoring method involves using a threshold comparator for monitoring a level of a call tone input signal (TRES). Its frequency is monitored by extracting frequency information transmitted to an evaluation microprocessor (MP) via a galvanic separation stage. A DC-DC voltage converter (WDL) controlled by a HF clock signal (TS) uses a pulse sequence containing the frequency information. Each of the pulses has a short duration relative to the half wave duration of the call time input signal to provide spaces in the HF clock signal, evaluated on the secondary side of the DC voltage converter to detect the frequency of the call time input signal. ADVANTAGE - Eliminates need for opto-coupler.
