Title: Method and means for composting waste or dust and the vehicle used therefor
IPC: A01C3/00
Filed: 1988-10-19
Abstract: A method for composting waste or refuse, in particular coarse refuse, such as bushes or the like, in which the waste is comminuted and transferred to a storage site, is to be improved in that the comminution of the waste takes place during its collection into the transport vehicle (10), and the comminuted refuse is directly passed by the said vehicle to a dumping gang (70). In addition, the comminuted refuse is to be conveyed to an impact chamber (86) which is enclosed all round, open at the bottom and projects upwards from the storage location - preferably by centrifugal force - and distributed therein to form a composting layer, after which the chamber is lifted by the height of the composting layer (M1) and additional building up takes place on the surface thereof to produce a further layer.

Abstract: A multilayer electronic circuit comprising at least three electronic circuit layers electrically interconnected by means of at least one interposed connecting layer which is conductive only in the Z-axis. Desirably at least four circuit layers are provided in two circuit layer pairs. Each pair comprises an insulating layer having opposing surfaces and having a circuit pattern on each of the opposing surfaces of the insulating layer.

Patent EP-0367030-A3 (EP)
IPC: C23C14/08
Filed: 1989-10-19
Abstract: A process for forming chromium dioxide thin films 
which are receptive to high density magnetic re­
cording. The process comprises depositing both 
chromium and oxygen on a substrate by evaporative 
techniques and concurrently bombarding the substrate 
with high energy ions of at least one of the film 
constituents to form a latent CrO x  film forming layer. 
The process is carried out at approximately room 
temperature.  
     The as-grown latent film forming layer is subsequently 
heat treated by a rapid thermal anneal step which 
raises the temperature of the as-grown fillm to about 
500°C. The rapid thermal anneal step preferably 
comprises a series of at least five separate pulses 
over a 10-second time span. After the rapid thermal 
anneal, the sample is rapidly quenched to room tem­
perature.

Abstract: The invention relates to an apparatus for rendering a 
plurality of sub-data processing systems to a fault 
tolerant system and a method for majority voting, wherein 
input signals supplied to the plurality of redundant sub­

a subsystem having a most reliable output signal to an­
other output signal of another subsystem having a lower 
reliable output signal in turn using self-diagnosis and 
cross-diagnosis in each subsystem according to majority 
voting rules. The output selecting circuit outputs a sig­
nal selected by the majority voting rules based on the 
output signals from the subsystems.

Title: Replacement switch
IPC: H04Q11/04
Filed: 1989-10-27
Abstract: A procedure for replacing an existing switch 
(62) with a greater-capacity replacement switch (12) in a 
communication system (10) is disclosed. The replacement 
switch (12) has redundant interconnect memories that 
can store different interconnect maps. The replacement 
switch (12) also has logic circuitry that forces the 
replacement switch (12) to operate using only a selected 
one of the redundant interconnect memories. The 
procedure loads a transparent map into the interconnect 
memories. Next, the procedure couples the replacement 
switch (12) in series between drop facilities (14) and the 
existing switch (62) and between the existing switch (62) 
and line facilities (16). The coupling scheme and 
transparent map route communication through both the 
replacement switch (12) and the existing switch (62) 
without substantially affecting service. Next, a master 
interconnection definition similar to an interconnection 
definition within the existing switch (62) is loaded into 
one of the redundant interconnect memories of the 
replacement switch (12). Operation of the replacement 
(12) is switched to utilize this master interconnection 
definition without affecting service.

Title: Table driving apparatus
IPC: H05K13/00
Filed: 1989-10-24
Abstract: Disclosed is a table driving apparatus adapted for 
use with an automatic mounting apparatus or assembling 
robot comprising a working table ( 1 ) movable in at 
least one direction, and a direct-drive motor ( 13, 15, 
30 ) having a rotary arm ( 11, 16 ). A mechanism ( 5, 6, 
10, 17 ) is provided for mechanically coupling the 
working table ( 1 ) and the rotary arm in such a manner 
that turning movement of the arm can be converted into 
linearly sliding movement of the working table along the 
one direction. The direct-drive motor ( 13, 15, 30 ) is 
coupled with the working table with such a small 
compliance that the resonance frequency of a system 
including the direct-drive motor and a load coupled 
therewith lies out of a frequency range within which the 
direct-drive motor is operable. This arrangement assures 
a rigid coupling between the direct-drive motor and the 
working table with a small compliance, so that the 
resonance frequency becomes much higher than otherwise 
coupled, thus enabling a stable and precise driving of 
the working table.

Patent EP-0393739-A3 (EP)
Title: Improvements in butter spreads
IPC: A23C15/16
Filed: 1990-04-02
Abstract: Butterfat spreads include products with around half the 
fat of butter. Around 15-20% of the fat-phase in butter 
is solid at 20°C. When butter is placed in the mouth 
this fat melts, produces a cool sensation on the palate. 
Low fat content attenuates the cool-melting properties, 
while adding stearins to the product can cure the mouth 
melt problem but gives a product which is hard when 
removed from the refrigerator.  
     The specification discloses a low fat butter spread in 
which the distribution of stearin in the product is 
inhomogeneous such that the C/N*N at 10°C is less than 
0.35. This spread is cool melting without being hard at 
fridge temperature.  
     The specification also discloses a process comprising 
the step of mixing of a pre-crystallized viscous butter 
stearin cream, having a gelled or thickened aqueous 
phase, with a fat-continuous emulsion of whole butterfat 
and water, preferably in a 30:70 ratio, to obtain these 
products.  
     Preferably the aqueous phase viscosity of the butter 
stearin cream is greater than 50mPa.s at 20°C as 
measured at a shear rate of 181 rpm after a resting 
period of 30 min.

Abstract: There are disclosed novel avermectin 
derivatives wherein the 3″- or 3′-methoxy group 
and/or the 4″- or 4′-hydroxyl group are replaced by 
hydrogen. The 3″- or 3′-desmethoxy-avermectins can 
further be derivatized at the 4″- or 4′-positions as 
the amino, semicarbazone or oxime analogs. The 3″- 
or 3′-desmethoxy-avermectins are prepared by the 
reaction of Samarium iodide on the corresponding 4″- 
or 4′-oxo-avermectins. The 4″-or 4′-deoxo-­
avermectins are prepared by radical deoxygenation of 
the corresponding hydroxy-avermectins. Di-de­
oxygenated avermectin derivatives are obtained by 
combination of these two methods or by treating 
avermectin aglycone or avermectin monosaccharide with 
a dihydropyran. The new compounds are potent 
anti-parasitic agents, in particular, the compounds 
are anthelmintic, insecticidal and acaridical agents.
