Title: Casing
IPC: E02D27/02
Filed: 1989-04-27
Abstract: Known casings for foundation parts for spread foundations are of channel-shaped design with constant spacing of the side walls, although it is already known that foundation parts of this type can perfectly well be narrower at their top side than at their bottom side. However, since the labour cost of a casing of this type with a narrowing cross-section is relatively high, the foundation parts, in practice, have hitherto been produced with a constant cross-section even with the known casing and the additional concrete requirement has been accepted. It is therefore proposed to use a lattice (5) consolidated with plastic film (6) for the novel casing (l, 11). Due to the flexibility of this material, the labour required for a casing of a foundation part with reduced cross-section can be decidedly reduced. <IMAGE>

Title: Electronic delay control circuit
IPC: H03K5/00
Filed: 1989-06-14
Abstract: An electronic delay control circuit provides 
small, constantly variable delays to an input pulse 
signal without altering the pulse width of the input 
signal. The input pulse signal together with a first 
reference signal are input to three comparators (12,14,16) in 
parallel. The output of one comparator (12) is a pulse 
signal corresponding to the input pulse signal, and 
the outputs of the other two comparators (14,16) are tied 
together and input to a pulse shaping network (18) to 
produce delay current pulses for the leading and 
trailing edges of the input pulse signal. The delay 
current pulses are added to the output pulse signal to 
produce a delayed output pulse signal. The delay 
current pulses are a function of the amount of a 
constant current steered (24, 26) between the two comparators (14,16) 
as determined by a delay control signal.

Patent EP-0339869-A3 (EP)
Title: Novel phenazine dyes
IPC: C09B57/00
Filed: 1989-04-20
Abstract: This invention relates to phenazine dyes, and more 
particularly, to phenazine dyes suitable as intermediates 
for leuco phenazine dyes. Essentially all of the phenazine 
dyes capable of providing red, orange, and magenta hues 
have unsubstituted amine groups at the 3- or 7-position, or 
both. The presence of unsubstituted amine groups at the 3- 
or 7-positions, or both, does not allow one to employ a 
simple, direct method to reduce and acylate the dye at the 
10-position without also acylating the dye at the 3- or 
7-position or both. In a reduced leuco dye which contains 
acyl groups at the 10-position as well as the 3- and/or 
7-positions, reoxidation under normal conditions removes 
only the acyl group at the 10-position, which will yield a 
dye form having different absorption properties from that 
of the original, unreduced dye containing the unsubstituted 
amine group. Therefore, phenazine dyes known in the art, 
such as phenosafranine, which are red, magenta, and the 
like, do not provide the original dye color upon reduction 
acylation and reoxidation. Although phenazine dyes 
containing substituents at the 3- and 7-positions are well 
known, essentially all of them provide turquoise or blue 
colors. This invention provides 3,7-diamino phenazine dyes 
having at least one electron-withdrawing substituent on at 
least one of the groups attached to the amine groups at the 
3- and 7-positions, provided that the algebraic sum of the 
para position Hammett sigma (σ p ) values for the groups 
attached to the nitrogen atoms of the amine groups at the 
3- and 7-positions is more positive than about -0.6. The 
group containing the electron-withdrawing substituent can 
be selected from: (1) a substituted alkyl group, and (2) a 
substituted aryl group.

Title: Glass melting furnace, and method of operating a furnace
IPC: C03B5/05
Filed: 1989-09-18
Abstract: A glass melting furnace comprises a base structure (6) defining a melting chamber (8) an intermediate chamber (10), and a working chamber (12), in which chambers heating means are located. An opening (22) is provided into the melting chamber (8), through which batch material may be deposited on the body of molten glass in the melting chamber. Glass flows from the melting chamber (8) through an outlet (26) at a lower part thereof, which opens into the intermediate chamber (10), and flows over a weir (30) from the intermediate chamber (10) into the working chamber. Located in the outer walls of the working chamber are working outlets (34), through which blowing irons or the like tools may be entered, for a manual withdrawal of molten glass from the chamber (12). The rate of production of molten glass by the melting chamber (8) is lower than the rate of utilisation, such that during a working shift the level of glass in the working chamber falls from a maximum level towards a minimum level, and outside the working shift (e.g. overnight) the level in the working chamber increases from the minumum level to a maximum level. Overflow ducts are provided, at locations which define the maximum level of glass in the working chamber i.e. a short distance below the locations of the working outlets (34).
