Patent EP-0323435-A3 (EP)
IPC: C02F1/48
Filed: 1988-12-23
Abstract: Nach dem Verfahren werden Flüssigkeiten, insbesondere strö­
mendes Wasser mit einem pulsierenden Magnetfeld behandelt, 
um vor allem Ablagerungen an den Wandungen von Leitungen und 
Behältern zu verhindern. Zur Erhöhung der Wirksamkeit und um 
zu erreichen, daß die für die Ablagerungsbildung kritischen 
"Poliwasser-Formate" in ihrer Resonanzfrequenz erregt werden, 
wird die Erregerfrequenz des Magnetfeldes betriebsabhängig 
aus zwei oder mehreren möglichen Frequenzwerten ausgewählt 
oder während des Betriebes zwischen vorgegebenen Grenzwer­
ten verändert.  
     Eine Vorrichtung zur Durchführung des Verfahrens, mit einer 
Magnetspule, die im Durchtrittsweg einer Flüssigkeit ein 
pulsierendes Magnetfeld erzeugt, besitzt eine Erregereinheit 
mit einem auf wenigstens zwei verschiedene Frequenzen ein­
stellbaren Oszillator.

Title: Method for continuous agglomeration of heavy metals contained in incinerator ash
IPC: C03C14/00
Filed: 1989-02-08
Abstract: Ashes (10) from municipal solid waste and toxic 
waste incinerators contain heavy metals harmful to the 
environment. This invention addresses a process in which 
the noncohesive ash (10) is agglomerated and/or encapsulat­
ed to substantially prevent dispersion of heavy metals to 
the environment. Ash (10) coming out of the incinerator is 
heated by means of an auxiliary burner or a plasma torch 
(14) to a temperature equal to or above its fusion or 
slagging temperature. In addition, low melting additives 
or fusion temperature lowering additives (19) may be mixed 
into the ash (10). A large fraction of the ash (10) will 
melt and form glass-like agglomerates which substantially 
reduce the leachate of toxic heavy metals. Thus, the 
agglomerated ash (10) is safe to be transported and dis­
posed in the landfill sites.

Title: Process for purifying sucrose fatty acid esters having a high hydrophilic-lipophilic balance
IPC: C07H1/00
Filed: 1989-06-27
Abstract: A process for recovering, in a purified form, 
sucrose fatty acid esters having a high HLB included in a 
reaction mixture formed by a reaction of sucrose and a 
fatty acid alkyl ester in an organic solvent as reaction 
medium in the presence of a catalyst, which comprises 
adjusting the reaction mixture from which a part of the 
organic solvent may be previously removed and to which 
water is added to form an aqueous solution, to a neutral 
pH region, adding a neutral salt and sucrose to the 
solution to precipitate the sucrose fatty acid esters, 
separating and washing the precipitate with an acidic 
water, and subjecting the washing liquid to 
ultrafiltration. The concentrate obtained by 
ultrafiltration may be spray-dried to form a dry powder 
of the sucrose esters having high HLB, and the liquid 
obtained by separating the precipitate may be contacted 
with a reverse osmosis membrane to recover sucrose. 
According to the invention, purifed sucrose fatty acid 
esters having high HLB can be obtained from the reaction 
mixture without using an organic solvent as purification 
solvent, while sucrose can be recovered in high yield.

Title: Microelectronic device based on mesoscopic phenomena
IPC: H01L29/78
Filed: 1989-09-21
Abstract: A new solid state device based on mesoscopic phenomena 
is described. A structure of the mesoscopic device (1) 
includes phase altering scattering sites (25) at various 
energy levels disposed in proximity to a conductive 
channel (16). The carriers in the channel (16), 
being isolated by a potential barrier (20), are not in 
substantial scattering interaction with the phase 
altering scattering sites (25) in the absence of a 
sufficiently large voltage at the gate (40) of the 
mesoscopic device (1). Increasing the potential at the 
gate (40), imposes a localized electric field along 
the channel (16), increases the energy levels of the 
carriers in the channel (16), and allows the carriers 
to interact with the phase altering scattering 
sites (25), thereby controllably varying the con­
ductance of the channel (16).

Title: Output control circuit for reversers, and high-frequency power supply for the dc supply of a welding station
IPC: B23K9/10
Filed: 1990-02-02
Abstract: A control circuit is provided for the output of a high frequency inverter of the type having an output transformer with a core, primary windings and a secondary winding with two sections for creating a first secondary current pulse of electrical current in one section when the primary windings magnetizes the core and a second secondary current pulse in the other of the secondary sections when the primary windings remagnetizes the core. By alternating switch means for passing current through the primaries to magnetize and remagnetize the core at a preselected rate the output current pulses are provided by the two sections of secondary windings. The control circuit of the present invention involves a modification of the output transformer secondary stage. A first auxiliary winding is connected to one of the secondary sections to create an auxiliary current pulse as the core of the transformer is magnetized. A means is then employed for limiting this auxiliary current pulse and for adding the limited auxiliary current pulse to the first secondary pulse created by the secondary section to which the auxiliary winding is connected. In a like manner, a second auxiliary winding is connected to the other of the secondary sections to create a second auxiliary current pulse as the core is remagnetized. Means are provided for limiting the second auxiliary current pulse and for adding the second auxiliary current pulse to the second secondary current pulse from the secondary winding. Addition of limited current pulses to secondary current pulses created by the inverter provides a maximum output voltage which is higher than the maximum output voltage normally available while conserving primary current under higher output current conditions.

service time allocation mechanism for limiting message 
service time relative to data transfer service time 
and for providing different amounts of data transfer 
service time for different ones of the multiple data 
buffers.
