Title: Organic compounds
IPC: C09B62/08
Filed: 1980-06-23
Abstract: Mono-azo reactants for fibers, having the formula:  (FORMULA) wherein the different meanings of the symbols R<u1>u to R<u6>u, Hal, m and n are given in claim 1, with the conditions that: a) n can not be zero and must be zero when R<u2>u is -NHCOOR<u10>u; b) the group -NHR<u5>u and the azo group are in ortho position one with respect to the other and are in the positions 1 and 2 and respectively 2 and 1 of the naphtalen ring, and c) when n equals 1, m equals 1 and the azo group is in position 1 of the naphtalen ring, then either R<u6>u in the position 8 of the ring is not a group OH or the sulphonic group is in a position other than position 4 of the ring, comprising at least two sulphonics groups per molecule, the mixture and the salts thereof. The compounds are obtained by coupling of the corresponding starting products and prior or subsequent condensation with the triazinic compound. They are used as dyes for the coloration or impression of substrates comprising nitrogen-containing groups or OH groups, such as for example natural or regenerated cellulose or natural or synthetic polyamides, particularly wool. Easily combinable, they are appropriate as elements for the trichromatic process, for example with coloring anthraquinonic acids.

Title: Fluid shut-off valve
IPC: F16K31/08
Filed: 1980-07-28
Abstract: A fluid shut-off valve is provided which comprises a magnetic valve body 5 provided in a non- magnetic hollow casing 1 for movement between a first position to open a fluid passage 3 and a second position on a valve seat 4 to close the passage, and an annular permanent magnet 8 provided outside said casing and urged toward the periphery of the valve seat 4 by an elastic spring 10. The valve body is normally held to the first position but is allowed to move to the second position by the magnetic force of the permanent magnet at a predetermined condition e.g. earthquake shock or in response to actuation of a solenoid 13 upon a leak being detected.

Title: Protective Membrane for Electrochromic Displays
IPC: G02F1/1524
Filed: 1980-08-11
Abstract: A protective and heat resisting membrane 20 for application onto electrochromic layers 11-13 and/or leads in an electrochromic display to prevent dissolution and erosion thereof as a result of contact with the display electrolyte 15 typically comprises (a) a long chain organic acid, preferably a water insoluble carboxylic acid, (b) optional acid resistant epoxy resin and (c) a compound selected from at least one of an amine and amide in sufficient amount to form the respective amino or amido salt of the acid, which salt together with any epoxy resin present, imparts water repellency and ionic conductivity to the membrane, and with the amine or amide being present in less than the amount required to fully cure any epoxy resin present with time and temperature so that only a minor, dispersed portion of the resin is cured. Curing of a minor, dispersed portion of the resin improves adherence and does not adversely affect the ionic conductivity of the membrane. In the examples, component (a) is oleic dodecanedioic or polystyrene sulphonic acid, component (c) is a polyamide, and ZrO2 pigment is present. <IMAGE>

Title: Drum synthesiser
IPC: G10H5/00
Filed: 1980-08-15
Abstract: An electronic drum synthesiser responsive to an input trigger pulse produces an output audio signal representative of the sound produced upon a drum being struck with a drum stick. The synthesiser includes a first circuit 6, 7 which gates a fast spike of broadband noise from a generator 8, to simulate the initial striking of the drum. A second circuit provides the noise signal from generator 8 to simulate the rattle of the wires of a snare drum. A third circuit includes a voltage controlled oscillator 11 operating at 600 Hz which modulates an oscillator 10 operating at 50-2KHz to produce a signal representative of the drumhead vibrating after its initial striking with a drumstick. The signals from the three circuits are selectively combined and gated to an output by voltage controlled amplifiers 3, 4 in dependence upon the magnitude of the input trigger pulse. <IMAGE>
