IPC: D06P1/08
Filed: 1971-05-11
Abstract: The invention comprises water-insoluble azo dyes of the general formula <FORM:1024485/C4-C5/1> where R is a nitro group-free residue of the benzene series, X is an acylamino radical, Y is hydrogen or halogen atom or a C1-C4 alkyl or C1-C4 alkoxy radical, R2 is a straight chain or branched unsubstituted or substituted C1-C4 alkyl radical or has the same meaning as R1, R1 denotes a grouping <FORM:1024485/C4-C5/2> where Z stands for a C2- 4 alkylene radical which may be substituted and R3 is a substituted or unsubstituted C1-C4 alkyl radical said dyes being free of sulphonic and carboxylic acid groups.  The dyes may also be prepared by reacting an appropriate dye containing a hydroxy group with a chloroformic acid alkyl ester to form the carbonate group.  The dyes are prepared by coupling an appropriate benzene series diazo component with an appropriate amine.  In an example, 4-cyano-aniline is diazotized and coupled with 1-N,N-di-[b (methoxycarbonyloxy) - ethyl] - amino - 3 - methoxyacetylamino - benzene to obtain an orange dye. Additional products are specified and a dyeing process described. The dyes are suitable for dyeing and printing textiles of polyethylene terephthalates, condensation products of terephthalic acid and 1,4-bis-hydroxy methyl - cyclohexane and cellulose acetates.

Title: Seismic exploration method - summing reflection signals for simulating strata response to wave energy
IPC: G01V1/30
Filed: 1978-02-03
Abstract: Seismic exploration method, based on spherical seismic waves, produces reflection signals in many receiver positions which are spaced over an area of large dimension relative to the seismic wavelength. These signals are summed up to forma signal for the source position which simulates the reflection response of the strata to the seismic wave energy. The enegy has a continuous wave front over a dimension which is large relative to the seismic wavelength. Arrangement achieves the advantages of multiple coverage stacking without the necessity for a common depth point stacking or a normal exit correction. The mass of data to the processed is reduced, and time and costs for seismic exploration are saved.

Patent NL-8701085-A (NL)
IPC: G11C29/00
Filed: 1987-05-08
Abstract: A memory is described which incorporates redundancy in the form of one or more redundant columns. An applied binary address is first distributed between predecoders which form a 1-out-of-2<n> code from n bits received. For each non-redundant column there is available a part of a main decoder, each part receiving a different combination of the bits supplied by the predecoders, thus selecting the column. For each redundant column there is provided a redundancy decoder. The latter decoder receives all bits supplied by the predecoders, each time via a series connection of a activatable gating element and a fuse element. Per predecoder the outputs of the series connections are combined in a wired logic function. Each wired logic function forms an input signal of the actual redundancy decoder. When a redundant column is to be addressed, all fuse elements but one of a group are opened and the gating elements are activated. A memory column to be replaced is then uncoupled by way of another fuse element.

Title: Safeguard against cable break for overhead doors which engages the round rail side
IPC: E06B9/84
Filed: 1993-07-15
Abstract: The invention relates to a braking mechanism for overhead doors which in the event of a cable break prevents uncontrolled closure of the door leaf by means of a chisel penetrating the round side of the door-runner rail. On doors already fitted it is not necessary to adapt the rail construction or the door leaf. The safeguard against cable break consists of a baseplate on which a hinged clip is mounted. The hinge pin (gudgeon) is also the space in which the bottom runner is fitted. By means of a twin auxiliary torsion bar (torsion spring), clip plus chisel are forced against the door- runner rail in the event of a cable break or a slack cable. The weight of the door will cause the chisel to penetrate the rail. The hinge point (pivot) is positioned between the panel and the chisel and has a play of 7.5 mm between chisel and round section of the door-runner rail. The safeguard against cable break is effective even in the bend of the rail. In the event of a cable break, the remaining cable produces no friction.

Title: Concrete mould and method of moulding concrete panels
IPC: B28B/
Filed: 1980-06-16
Abstract: The mould for casting concrete panels on a casting bed includes end members and side members which form a casting box for casting at least one concrete panel.
