Patent EP-0355886-A1 (EP)
Inventor: VAN DIJK JOHANNIS CORNELIS
IPC: C02F5/06
Filed: 1989-07-28
Abstract: The present invention relates to a process for chemical softening of water with the crystallization method in a pellet reactor, whereby water in the presence of a crystallization promoting seeding material is mixed with a separately injected alkaline agent which crystallizes the hardness components on the seeding material. 
     A characteristic feature of the invention is that a part of the water to be softened is softened deeply in the reactor, which is provided with the seeding material of a suitable grain size, and the softened water thus treated is mixed up with not softened water outside the reactor in such a ratio, that the resulting mixed water has the desired hardness. 
     The grain size of the seeding material is usually from 0,1 to 0,8 mm and preferably from 0,2 to 0,4 mm, whereas the size of the pellets to be removed from the reactor is 0,8 - 3 mm and preferably 0,8 - 1,2 mm.

Abstract: A curd and whey mixture is drained of loose whey on a conveyor and the dry curd fed into the top of a tubular perforated column (4) maintained under sub-atmospheric pressure to form a pillar of curd. A mass of curd severed from the lower end of the pillar is deposited in a mould (14) mounted on a turntable (13) rotatable to index the mould in succession at six pressing stations at each of which the curd is compressed for 45-120 seconds at a pressure of at least 4 bar in order to form a block of cheese with a rind firm enough to permit handling of the cheese block after ejection from the mould. At the first pressing station the curd is subjected to a sub-atmospheric pressure of -0.9 to -1.0 bar prior to compression. After the cheese block is ejected from the mould, the turntable returns the empty mould to the column for reception of another mass of curd.

Abstract: Disclosed is an ophthalomological diagnosis method and apparatus in which a blood vessel (61, 68) in the eye fundus (18b) is illuminated with a laser beam (60, 60′) of a predetermined beam spot whose diameter is substantially equal to or smaller than that of the blood vessel in order to produce diffraction-plane speckles (63) which are formed at a Fourier-transform plane (F) by light scattered from the eye fundus. Boiling motion of the diffraction-­plane speckle pattern thus produced is then detected through a multiple detection aperture pattern (62) which is disposed at the Fourier-transform plane (F) and comprised of a plurality of small apertures (65′) to obtain a speckle signal which is evaluated to measure velocity of the blood flowing through the blood vessel concerned. This arrangement makes it possible to detect the speckle signal without any effect of averaging the signal with an increase in intensity detected, thus enabling advantageous and successful measurement of the blood flow state in the eye fundus.

Abstract: A pressure modulated flow control valve (13) for use in water irrigation systems has an unitary elastomeric pin (24) to define at least one flow passage (32) and a flexible diaphragm (35) overlying the flow passage, adjacent to an inlet to the valve. In operation, the diaphragm (25) is exposed to water pressure prevalent at the inlet to the valve (13) to flex into and vary the size of the passage (32) to control and modulate the flow rate therethrough. The diaphragm may function to maintain a micro flow rate through the passage "near constant", e.g., selected from within the approximate overall maximum range of from 2.0 gph to 60.0 gph (7,6ℓ/h to 227ℓ/h). The pin (24) is interchangable in a housing (20) of the control valve to effect the desired near constant flow rate and is particularly adapted for use in pressure modulated drip-irrigation systems wherein water is communicated through the valve to a water distributing device, such as a sprayer or drip-type emitter.

Abstract: According to the present invention, a CMOS interface circuit (C2) similar to a latch made by two CMOS cross coupled inverters (INV1, INV2) is placed directly on the output node (14) of conventional BICMOS logic circuit (11) operating alone in a partial swing mode. This latch is made of four FETs P5, P6, N8, N9 cross-coupled in a con­ventional way with the feedback loop connected to said output node (14) The partial voltage swing (VBE to VH-VBE) naturally given by the output bipolar transistors (T1, T2) mounted in an push pull configuration is rein­forced to full swing (GND to VH) by the latch at the end of each transition The state of the output node is forced by the latch because of the high driving capability due to the presence of said output bipolar transistors (T1, T2). As a result, the improved BICMOS logic circuit (D2) has an output signal (S) that ranges within the desired full swing voltage at the output terminal (15). It is a charac­teristic of this embodiment that the structure of CMOS interface circuit (C2) is always independent of the logic function implemented in the conventional BICMOS logic circuit (11). More generally, the CMOS interface circuit may have various physical implementations, however, it is always comprised of CMOS FETs and it becomes active at least in one of the GND to VBE or (VH - BE) to VH range.

Abstract: Fuel tanks, on the top side of which a vent line of a flexible material is arranged, are already known. In order to prevent compression of the vent line, the vent line is laid in a recess formed in the fuel tank. This leads to a reduction in cross section and to the formation of cavities in which air pockets form even when the tank is completely full. The reduction in cross section leads to strength problems particularly in the case of a fuel tank which consists of two opposing chambers which are connected to one another via an overflow pipe. The new vent line is intended to avoid the said disadvantages. This is achieved in that the vent line (1) is made from a dimensionally stable material and is connected at one of its ends by way of a fixed bearing (28) and at its opposite, other end via a movable bearing (20) to the surface of the fuel tank (1). The vent line is particularly suitable for plastic fuel tanks. <IMAGE>

Abstract: Polymeric compositions exhibiting superior physical properties, useful in the fabrication of composites and other applications, are prepared by the polymerization of thermotropic, monomeric materials having orderable molecular structures. The monomers comprise molecules containing mesogen groups with side chains on either end thereof terminated with reactive groups, the reactive groups being separated from the mesogens by spacer atoms. The monomers are polymerized in their crystalline or liquid crystalline state, or under conditions which assure that at least part of the monomeric molecules are in an ordered state. The reactive groups which are consequently in proximity with each other, are thereby capable of interaction without molecular diffusion, allowing substantially complete polymerizations to be achieved despite the increasing conversion and glass transition temperatures of the polymers being formed.

Abstract: A method of establishing an ultrasonic standing wave in a fluid medium is described in which the standing wave is produced by an acoustic energy output along a path extending through the fluid medium, the frequency of said energy output being changed cyclically while maintaining an essentially constant mean frequency. The cyclic frequency change sweeps said energy output frequency between upper and lower limits that represent a difference of at least one half-wavelength at the mean acoustic frequency over the length of said path, so that a fully resonant standing wave appears in each cycle, regardless of transient ambient variations. For stability, the cycle time of the sweep is maintained substantially greater than the travel time of the acoustic energy output over the length of the path.

Abstract: An apparatus for welding with digital control is described wherein the welding current is controlled by an analog programmer (14) which commands the evolution of the current as per the program, which is to be laid down as required. The weld current is controlled by a counterreaction ring (11) circuit effective for detecting the impedances of line and for automatically compensating the fluctuations of impedance of the arc. The electric efficiency is optimized by using a generator which is provided with an automatic control of the voltage across the current regulator (3), for the purpose of maintaining the voltage within the limits of safety. When the voltage exceeds one of the two thresholds, minimum or maximum, the regulation system provides to restore said voltage within said limits through the insertion and disinsertion of the feeding transformers.
