Title: Reactive dyestuffs containing chlorine or fluorine substituents and one or more 1,3-dicyanobenzene radicals linked to the dyestuff at the 2-, 4- or 6-position
IPC: C09B62/78
Filed: 1979-04-24
Abstract: Dyestuffs are provided which contain one or more 1,3-dicyanobenzene radicals linked to the dyestuff at the 2-, 4- or 6-position, with halogen substituents in both of the remaining two of these positions and an electron-attracting substituent in the 5-position. These dyestuffs reactively dye cellulose at low temperatures and are less prone to "acid-bleeding" than some known reactive dyes. More particularly, those dyestuffs have the formula: < IMAGE > (1) where D is a chromophoric group n is 1 or 2, < IMAGE > where R is H, C1-4alkyl, C1-4alkyl substituted by OH, OSO3H, CN or SO3H or is phenyl. Each hal independently represents a chlorine or fluorine atom occupying one of the remaining 2-, 4- and 6-positions of the benzene nucleus, and Y is H, F, Cl, CN, NO2 or SO3H.

Title: Apparatus and method for generating waveforms which are particularly suitable for a PWM- driven motor
IPC: H03K/
Filed: 1979-12-11
Abstract: A triangle waveform having substantially linearly sloped, gradually increasing and decreasing edges and having a frequency nf is generated from an n-phase sine wave signal, each phase having a fundamental frequency f. A segment of any of the n-phases of the sine wave is detected when that segment is within a predetermined angular amount from a reference crossing level, such as the zero crossing of the sine wave signal. Successive ones of the detected segments are selected to synthesize the triangle waveform. In the preferred use of this invention, the triangle waveform is compared to a reference signal, such as the sine wave signal from which the triangle waveform is generated, this reference signal having a controllable frequency and amplitude. Pulse transitions are generated at the intersection of the triangle waveform and each of the respective phases of the reference signal. In one embodiment of this invention, the frequency of the triangle waveform is increased by an amplitude- folding technique wherein the triangle waveform (of frequency nf) is folded about a pair of equal but opposite folding levels whenever the triangle waveform reaches either of these levels, so as to produce an amplitude-folded triangle waveform of frequency mf and of peak levels determined by the folding levels.

Title: Power supply with nuclear reactor
IPC: G21C9/00
Filed: 1982-04-07
Abstract: Each parameter of the processes of the nuclear reactor and of the components of a power supply which convert the thermal energy generated by the reactor into electrical power is monitored by a set of four like sensors. One each of the unlike sensors which monitor the different parameters is contained in a reactor-trip logic channel. Each such unlike sensor is referred to here as a "local sensor". Each channel is interlocked with the other three channels and receives the signals sensed by the other three sensors, herein called "remote sensors". Each channel also includes means for processing the signals from the local and remote sensors. The apparatus also includes means for tripping the reactor to deenergize or trip the control rod drive and insert the control rods fully into the core so that the reactor stops supplying power. The apparatus normally operates on a "two out of four" configuration. This assumes that all sensors are in normal operating condition. To achieve this purpose, eight circuit breakers are provided. Two breaker contactors are controlled by each channel. The control is through the undervoltage relays of the respective breakers. To trip the reactor, it is necessary that at least four breaker contactors be opened by operation of two channels.

Title: Automatic shut off valve.
IPC: F16K17/00
Filed: 1984-08-16
Abstract: An automatic shut off valve comprising a housing having a main inlet, an outlet, a user inlet and a user outlet. A valve assembly is contained within the housing and is movable between an open and a closed position. In its open position, the user inlet and outlet are fluidly connected in series with the main inlet and main outlet while, conversely, in its closed position, the valve assembly sealingly closes and isolates both the user inlet and outlet from the main inlet and main outlet. A compression spring urges the valve assembly towards its closed position while a fluid flow rate greater than a predetermined amount into the user inlet retains the valve assembly in its open position. Consequently, in the event of an interruption or blockage of the fluid flow between the user inlet and outlet, the compression spring snaps the valve assembly to its closed position thus isolating the inlet and outlet from the main inlet and terminating fluid flow through the shut off valve. In the preferred form of the invention, a flow indicator provides an exteriorly visible indication of the flow rate through the shut off valve.

Patent ES-8702768-A1 (ES)
Title: Plough.
IPC: A01B15/02
Filed: 1985-06-27
Abstract: A chisel plow including a landside attached rearwardly of the chisel shovels. The landside is disposed to extend generally fore-and-aft and is disposed laterally outward to one of the lateral edges of the chisel shovel. As the chisel plow travels forwardly through the soil, each chisel shovel forms a fore-and-aft furrow defined by opposing furrow walls cut by the lateral edges of the chisel shovel. The landside bears against one of the furrow walls to counteract forces which tend toward an overcutting or undercutting condition. Structure is provided to allow the selective mounting of the landside to be disposed laterally outward to either of the lateral edges of the chisel shovel to control overcutting or undercutting. This results in improved functional performance of the entire chisel plow implement by allowing it to maintain its proper width of cut.
