Title: Method and device for cleaning material surfaces
Inventor: KALWAR KLAUS
IPC: B08B7/00
Filed: 1985-10-30
Abstract: A method and a device according to the invention are created such that material surfaces can be cleaned by means of a corona discharge.   In this case, the dust particles are in practice forced off the material surface by the discharges produced during the corona treatment, and are subsequently vapourised to a greater or lesser extent. Particularly when the surface is a transportation roller 2, by means of which a goods web 4 is transported or guided, the method according to the invention and the device can be used in a particularly advantageous manner. In the case of this application, the corona discharge for cleaning takes place when the transportation roller 2 is rotating, on two regions 9 which run parallel to one another and to the longitudinal axis of the transportation roller 2. A cleaning electrode 3 is connected in a known manner to a generator 1 which produces high voltage, while the transportation roller 2 is connected to earth. At the same time, the dirt which has been released and the ozone gas produced during a corona discharge are sucked away via a vacuum system 7. The corona discharge can take place both continuously and intermittently. <IMAGE>

Patent DE-3608881-A1 (DE)
Title: Magnetic grader (separator)
Inventor: BARTH ERWIN
IPC: B03C1/22
Filed: 1986-03-17
Abstract: Constructed between the underside of a magnet (16) and the inside of the bottom strand (36) of a discharge (delivery) belt (18) of a magnetic grader (12) is an air cushion which is bounded, for example, by a bellows (38). Owing to the construction of the air cushion, the discharge belt (18) "floats" on the underside of the magnet (16), with the result that the friction between the magnet (16) and the discharge belt (18) is greatly reduced. This has, on the one hand, the advantage that a lower power suffices to drive the discharge belt (18) and, on the other hand, that wear of the discharge belt (18) is strongly reduced, since there is a reduction in the attractive force between the magnet and iron parts occurring from the flow (40) of material on the underside of the discharge belt (18). <IMAGE>

Patent DE-3610408-A1 (DE)
Title: Two-stage semi-dry desulphurisation process
Inventor: HOELTER HEINZ DIPL ING
IPC: B01D53/60
Filed: 1986-03-27
Abstract: It is known to bind flue gas by dry hydrated lime in the region of a spray absorber or a contact section. Separating off, e.g., 95% of SO2 means adding moisture in spray absorbers which cools the gas virtually to dew point and, as a consequence, reheating is necessary for delivery of the gas to the stack downstream of the filter. In order to avoid this disadvantage, according to the invention it is proposed that, for gas separation with low temperature decrease, the hydrated lime effects dry at (3) a separation efficiency of about 70% and more, based on the untreated gas loading, and the used lime is transferred at (5) only slightly moistened and at (6) to the spray absorber (2), in order to be separated off from the process at (7) as used lime. <IMAGE>

Title: Filter calibration method and device for implementing it
Inventor: FUENFGELDER HELMUT DIPL ING
IPC: H03H3/00
Filed: 1986-04-28
Abstract: Transmitters, particularly shortwave transmitters, for transmitting voice and data must meet high requirements for the linearity of their characteristics. Since the transmitter output stages used cannot meet these requirements for the linearity, particularly when they are constructed in the form of wide-band transistor power amplifiers, a filter arrangement is provided at the output end of the transmitter output amplifier, the suboctave filters of which, allocated to different frequency subranges, can be inserted optionally into the connecting path between the output of the transmitter output amplifier and the antenna for suppressing unwanted harmonics. To reduce the production expenditure in manufacturing such filter arrangements, it is proposed to build up the filter arrangement by means of resonant-circuit modules (SK) which are in each case separately calibrated for their nominal frequency with the aid of a calibrating device (O, AD, FZ, SV) before they are inserted and soldered to the circuit board (LP) common to the modules. <IMAGE>

Title: Method for traffic-dependent determination of the green time in road traffic signal installations
Inventor: BOETTGER ROLF DR ING
IPC: G08G1/08
Filed: 1986-06-30
Abstract: In the method according to the invention for traffic-dependent determination of the green time in signal installations with control devices for traffic junctions and with vehicle detectors (D1, D2) which are arranged in the respective approaches at a particular distance (DA1, DA2) from the stop line (HL1, HL2), a current degree of utilisation ag1 for the green time (Sg1) and ar2 for the red time is continuously calculated in each case from the detector messages both during the green time and during the red time during the entire signal cycle for each signal group (Sg1, Sg2) determined. The degree of utilisation ag1 of the currently running green time is compared with the degree of utilisation ar2 of the hostile signal group (Sg2) which is on red, the current green time being ended when ag1 is shorter than ar2. The degree of utilisation ag is calculated second by second from the number Z of vehicles (Fz) determined, referred to a maximum performance AB of the current green time for the corresponding signal approach. The degree of utilisation ar is calculated from the number ST of accumulated vehicles (Fz) referred to a green capacity GK which is equal to the mean green time G (in s) of the associated signal group from the preceding signal cycles multiplied by the saturation flow S (in Fz/s). <IMAGE>

Title: Method of filling pressure capsules with different commercial gases
Inventor: JAHN GERWIN DIPL ING
IPC: F17C5/00
Filed: 1986-11-05
Abstract: High-purity gases and standard gas mixtures in smaller volumes are available on the market in pressure capsules. Fillings differing from this, in particular in the case of gas mixtures those with different volume ratios and/or other high-purity gases as components, are usually only obtainable at high cost and with long delivery periods. A station (10), e.g. at the producers of commercial gases and at their branch establishments and suppliers and also at consumers of larger volumes, permits with automatic, program-controlled operations the requisite venting of the system, flushing operations and the individual filling operations. Supplies of commercial gases, which are prepared under high pressure in pure form for withdrawal, for example, from high-pressure steel cylinders 15a, ... 15n (F10/F50), serve to fill pressure capsules 22a, ... 22n, in particular with gas mixtures of individually selected compositions.

Title: Process and device for injection-moulding moulded parts from at least two different plastic components
Inventor: ECKHARDT HELMUT DIPL ING
IPC: B29C45/16
Filed: 1987-04-02
Abstract: A process for injection-moulding moulded parts from at least two different plastic components, for example a skin material and a core material, is described, in which the plastic components are filled in a specific sequence and with a predeterminable quantity in each case into the mould cavities of moulds and, in the process, they are distributed therein as uniformly as possible, forming the moulded parts. In the process, regions are formed on the moulded parts in which one plastic component, for example the core material, penetrates the other plastic component, for example the skin material, from the inside outwards. This is achieved in that, during filling of the plastic components, first the predetermined filling volume of the mould cavities is selectively reduced and held until filling is complete, in that then the maximum filling volume is released and, at the same time and/or subsequently, a corresponding amount of a predetermined plastic component, for example the core material, is post-filled to the mould cavity.
