Patent DE-3534580-A1 (DE)
Title: Switching-voltage regulator
Inventor: VOS FREDDY DE
IPC: H02M3/156
Filed: 1985-09-27
Abstract: The semiconductor switching element which is provided in the switching-voltage regulator represents a field-effect transistor (power MOS transistor SI). The output voltage which is produced on the charge capacitor (C) is evaluated by a differential amplifier (R4 to R7, OP) at whose output the respective actual value (Ui) is picked off for an integrated regulator and control arrangement (RS). The actual voltage is supplied by the differential amplifier back to that reference point to which those voltages are related which govern the regulator and control arrangement (RS). At the same time, the actual voltage is changed to a voltage level which can be processed directly by this module (chip) and is matched to the reference voltage level. <IMAGE>

Title: Process for determining the time point for exchanging press moulds
Inventor: FEISTNER KARLHEINZ
IPC: C03B11/16
Filed: 1986-01-16
Abstract: The invention relates to a process for determining the time point for exchanging press moulds for the pressing of glass articles in cyclically operating pressing devices, which process may be used in particular in the pressing of diffusers. The aim is to make the pressing process more uniform and to allow optimum utilisation of the press tools for quality improvement and reduction of rejects, for example in the case of diffusers for motor vehicle headlamps. The object was based on developing a process for determining the time point for the exchange of the press moulds in cyclically operating pressing devices, by means of which the operational effort for setting the mould cooling can be reduced to a minimum and quality reductions associated therewith resulting from cold waves on the pressed article are eliminated. For this purpose, according to the invention, for each mould the time between a time point, which is always the same, at the start of the demoulding process and a second time point at the end of the demoulding is measured and these measured values for the same mould, which characterise the demoulding duration, are compared with the measured values of other moulds of the same pressing device or with a reference value.

Title: Filter for filtering out fatty particles from a gas stream, in particular from kitchen exhaust air
Inventor: SCHMALHOFER MARKUS
IPC: B01D45/04
Filed: 1986-03-24
Abstract: Warm fat-containing exhaust air cools on filter surfaces (3a) impinged with cooling liquid (10) beneath the condensation or melting temperature of the oil or fat particles contained in the exhaust air. The fat particles depositing on the cooled filter surfaces (3a) run off downwards as a result of the action of gravity. As a consequence of the intense cooling, water vapour also contained in the exhaust air (6) condenses out in not insignificant amounts, as a result of which a certain "washing effect" or self-cleaning effect of the filter surfaces (3a) is achieved. In order to prevent permanent deposits on the filter surfaces (3a), the filter surfaces are periodically cleaned from time to time by mechanical cleaning elements (16). <IMAGE>

Title: Method for the ventilation drying of corn, rape and other cereals
Inventor: STINGL KARL
IPC: A01F25/22
Filed: 1986-06-13
Abstract: The invention relates to a method for the ventilation drying of corn, rape and other cereals dumped in heaps in warehouses, silos or other storage facilities. In this method, fresh air extracted from the atmosphere is heated and is then made to flow as incoming air through the heaps of cereals. So that this method can be operated as continuously as possible, even in the event of a change in temperature of the fresh air, according to the invention the fresh air is heated uniformly or essentially uniformly to or virtually to the grain temperature, so that the incoming air flowing through the grain remains uniformly or essentially uniformly at the grain temperature day and night, irrespective of the outside temperature. This constant temperature of the incoming air should be maintained unchanged until the end of drying. By means of the method according to the invention, a moistening of the grain, which can occur at a high fresh-air temperature, is completely or largely avoided, and it ensures that the grain remains sound.

Title: Gas pressure control apparatus having two membrane-controlled valve devices
Inventor: GOTTFRIED JOSEF DIPL ING
IPC: F17C13/04
Filed: 1986-07-22
Abstract: Gas pressure control apparatuses having two membrane-controlled valve devices are installed in particular vehicles whose gas supply system is fed from a liquid gas bottle. Different installation conditions in the bottle case of the vehicles require a different attachment facility and different line connecting facilities for this gas pressure control apparatus which is additionally exposed to the vibrations of the vehicle and, by means of a double-walled housing 2, 4, the connecting nozzles 5, 7, 8 are therefore given a very sturdy attachment to said housing. The different attachment facility and line guiding is made possible due to the exchangeability of the attachment nozzle 8a with the outlet nozzle 7a at an angle of 90 DEG to one another. <IMAGE>

Title: Closure for savings boxes
Inventor: HILDNER LUTZ
IPC: A45C1/12
Filed: 1986-09-09
Abstract: The invention relates to a closure for savings boxes, consisting of a covering plate made of metal, a lock housing made of plastic with a moulded-on collar for resting on the body of the savings box, and two identical latches which are located opposite each other, are under spring tension and can be displaced synchronously, and a carrier which is centred by a key bolt and is locked under spring tension in its end position by means of a key after retraction of the extended latch in order to be able to insert the savings box lock vertically into the savings box aperture without it becoming jammed. Closure is then effected by the carrier under spring tension sliding out of its locking position due to finger pressure on the key bolt and thus allowing the latches, likewise under spring tension, to extend synchronously, carrying the carrier along from the lock housing into the closed position. The savings box is thus closed without using a key.

Title: Safety circuit for electrical heating or warming apparatuses which are operated with AC voltage
Inventor: MERK ERNST
IPC: G05D23/24
Filed: 1987-02-26
Abstract: The safety circuit is provided for electrical heating or warming apparatuses which are operated with AC voltage, in the case of which the heating conductor (1) of the apparatus is connected to the operating AC voltage in series with an interrupter element (2) which opens in the event of a hazard situation and in consequence isolates the heating conductor (1) from the operating AC voltage by thermal tripping. A sensor line (5) which is arranged physically parallel to the heating conductor and extends essentially over its entire length is isolated from the heating conductor (1) by an insulator layer (6) which has a relatively high impedance (which reduces as the temperature rises) at the normal operating temperature and/or which melts above a safety temperature. Furthermore, a heating element (7) is provided which acts thermally on the interrupter element (2) and whose heating power is controlled by the leakage current flowing from the heating conductor (1) via the insulating layer (6) to the sensor line (5) and flowing from there to one of the connections (8) of the operating AC voltage. A discriminator circuit, which responds if a predetermined value of the leakage current is exceeded, and/or an amplifier stage (9) are/is connected to the sensor line (5), which amplifier stage (9) supplies the heating element (7) from the operating AC voltage. <IMAGE>
Patent DE-3706363-A1 (DE)
Title: Hydrostatic height measuring device
Inventor: BECK ELMAR DIPL ING
IPC: G01C5/04
Filed: 1987-02-27
Abstract: The invention relates to a measuring device for height differences between at least two locations located remotely from one another which are connected to one another by a fluid line which has a vessel with a free fluid surface at only one reference location. At the measuring locations, pressures in the fluid line are measured by means of electric pressure sensors. The required height difference is calculated from the pressures. To eliminate measuring errors, the height of the fluid column at the reference location is temporarily changed by at least one controlled measure by an automatic control in each measuring cycle and the respective pressures are measured. In addition, the pressure sensors are temporarily disconnected from the fluid line in order to use them for measuring the pressures in fluid columns at the measuring locations. At the same time, a check is made by measuring the pressure in a parallel unchangeable fluid line as to whether the object being measured has changed its height position in the meantime. If necessary, the measuring processes are automatically repeated. To eliminate further measuring errors, the two fluid lines are temporarily connected to one another in such a manner that a circuit can be generated by means of which temperature differences in the fluid can be equalised.
