Patent NL-7007117-A (NL)
Title: Dyeing polyamides - from non-aqueous baths by means of 1 2 metal - complex dyes
IPC: D06P3/24
Filed: 1970-05-15
Abstract: Metal complex dyes are used to dye polyamide fibres from non-aqs. solvents at 15-120 degrees C. The fibres may be in the form of threads, flat goods and textiles. Dyeing may be batchwise or continuous. The non-aqs. solvent is particularly a chlorinated hydrocarbon. The final stages in the prepn. of the dye, necessary if the dye is to be used from an aqs. bath, can be omitted. Better utilisation of the dye, esp. in a batch process, is obtained. The dye has improved fastness in the wet state. A wider range of dyes becomes available for dyeing from non-aqs. baths.

Title: Grocery bag of plastic sheet - with relatively thick profiled reinforcing strip
IPC: B65D33/02
Filed: 1971-12-07
Abstract: The bag has a rectilinear mouth in the folded state, and a reinforcing selvage parallel to the mouth and consisting of a strip with a transverse profile several times the wall thickness.

Title: Taximeter with DC tachogenerator coupled to speed unit - has voltage source producing output signal corresponding to time function
IPC: G07B13/00
Filed: 1974-12-09
Abstract: The taximeter (10) contains a d.c. tachogenerator (12), with an input spindle which can be coupled either to the speed cable of the taxi or the gear box or the wheels. The tachogenerator provides a direct current output signal which is proportional to the speed of the vehicle. A constant voltage source (14) produces an output signal which corresponds to the time function. The two outputs are fed to a direct voltage selection unit (16), which selects the higher of the two which is then fed to a voltage controlled oscillator (18). The output of the oscillator is fed to a counter (21) whose output is then fed to a digital read-out unit (22). The readout is a function of the analogue signal, when the latter is such that it corresponds to the movement of the vehicle at a speed that is less than a predetermined value.

Title: Punch-press with multiple tool rotating head - with means for automatically indexing rotary head and for positioning workpiece in horizontal plane
IPC: B21D28/24
Filed: 1978-02-24
Abstract: A punch-press is described with two rotating heads, the upper for carrying the punch tools and the lower for carrying the matrices. The heads are automatically indexed by means of electronic sensors, a control panel and a hydraulic positioning cylinder and piston. The hydraulic fluid is pneumatically pressurised in vessels, the air flow being regulated by means of solenoids connected directly to the control system. The heads are rotated by means of rack and pinion drives, the indexing being in two stages, rapid feed and slow feed. The heads are finally locked in position by means of pins and positional holes. The press incorporates clamps for mounting the workpiece and screw feeds for positioning the workpiece in a horizontal plane. The punches are driven by means of an accentric and press. The rotating punch head can carry a variety of tools on different radials and several tools along each radial. The matrix head carries a corresponding number of matrices. The supporting structure and mechanism eliminates any tendency toward misalignment of the punch, workpiece and matrix. The rotating heads can carry a large number and variety of tools.

Title: Glutaraldehyde sterilisation of fermentation media - with greatly reduced energy use compared with steam sterilisation
IPC: C12N1/38
Filed: 1978-05-02
Abstract: Sterilisation of microbiological media for fermentation by: (a) treating the medium with glutaraldehyde; (b) adjusting the pH of the sterilized medium from (a) to >6.5; and (c) treating the medium from (b) with >=1 nitrogenous cpds. e.g. ammonia, prim. amines, sec. amines, heterocyclic amines, ureas and amides to inactivate the glutaraldehyde. Large savings in energy are achieved c.f. conventional steam-sterilising process, and equipment is less costly. There is a lower loss in nutrients than in steam sterilising. A typical medium for benzylpenicillin fermentation was sterilized with glutaraldehyde (0.1%) at 24 degrees C and pH 5.5, NaOH was added to pH 7 and formed NH3 from (NH4) in the medium which neutralised the glutaraldehyde.

Title: Biological purificn. of waste water contg. nitrogen cpds. - using oxygen acceptor pre-neutralised with calcium carbonate or active slurry
IPC: C02F3/30
Filed: 1980-01-17

The pH of the oxygen acceptor is esp. less than 4 (less than 3) and neutralisation is pref. to pH 4-6 (4-5). CaCO3 is esp. used as marl. The active slurry is pref. from a settling or concn. basin in which the purified waste water is sepd. from the slurry. Acid waste streams can be used as oxygen acceptor, without addn. of extra Ca(OH)2 to raise the pH. A smaller amt. of active slurry is produced.

IPC: F16L47/06
Filed: 1982-04-23
Abstract: A plastic pipe part 1 is pushed across a head part 3 of a sealing sleeve 4, being supported by a support 8, thereby providing the plastic pipe part with a widened end 7. Subsequently the widened end is surrounded by an outer mold 11 with three successive widenings 12, 14, 15 and by means of a fluid pressure in the interior of the widened end 7, sealed by the head part 3, the widened end is provided with three socket end widenings 28, 22, 29. After removal of the support 8 the end portion 6 of the socket end is inwardly rebent around the head part 3 thus forming a groove chamber 5 retaining the head part 3 of sealing sleeve 4. Pushing the plastic pipe part across the head part is facilitated by applying a fluid pressure. An apparatus for performing this method comprises an outer mold 5 with three successive mold widenings 12, 14, 15, a first mandrel 20, a second mandrel 21, a third mandrel 30, a fourth mandrel 31, a removable support mandrel 8, a rebending member 26 and a supply conduit 10 for supplying a fluid under pressure in the space between outer mold 11 and the mandrels 30, 20, 21.

Title: Fast battery charger with mains input transformer - uses double electrolytic capacitor t6o join sec. of input transformer to prim. of output transformer
IPC: H02J7/02
Filed: 1982-09-24
Abstract: The fast battery charger has its a.c. voltage input connected to the prim. winding (A1) of a first transformer (T1) whose sec. winding (B1) is connected via a double electrolytic capacitor (C1) to the prim. winding (B2) of a second transformer (T2) whose own sec. winding (A2) is connected to one diagonal of a full-wave rectifier (D). A second double electrolytic capacitor (C2) is connected across the rectifier bridge's second diagonal, which also forms the d.c. charging output. When the circuit is connected to the a.c. supply, it oscillates and an output voltage is produced that increases when the battery being charged is connected and charges it within 11-120 seconds. The oscillations cause an a.c. voltage of 75V at the sec. of the first transformer and the prim. of the second transformer for a 220V mains supply.

Patent NL-8602053-A (NL)
Title: Automatic watermark detection system - uses near IR radiation as part of banknote checking and counting machine
IPC: G07D7/00
Filed: 1986-08-12
Abstract: Light from a source e.g., a halogen lamp, is fed to a first optical focussing element. The source produces light at the near-infra-red end of the spectrum. The beam passes through a slit in a diaphragm, and a second optical element consisting of a compound lens and near-infra-red filter. The filtered light focussed down to a point on the transport mechanism which carries a series of notes to be checked. The near-infra-red light passes more easily through the watermark than the rest of the paper. The light passing through the note is condensed into a parallel beam which is split, by a semi-transmissive mirror, into two beams. One beam falls onto a first near-infra-red detector, while the other beam is diffused before reaching a second detector. The second detector output is used by a data processing system to establish a reference for the signal from the first detector.

Abstract: The implantable catheter device has a capsule (10) with a perforatable upper wall (15). A catheter (11) leads into a cavity (12) in the capsule (10). The catheter (11) is fixed to the capsule (10) by means of an elastomeric clamping piece (30), which is arranged in the inside of a connection piece (22). The connection piece (22) has an internal thread (23) in which an external thread of a thrust piece (26) engages. By turning the thrust piece (26), the clamping piece (30) is deformed, in order to press against the periphery of the catheter and fix the latter and seal it off relative to the capsule (10). The lateral dimensions of the capsule (10) are not increased by the connection piece (22). The catheter coupling can be easily tightened and released, and it affords satisfactory safety against the catheter being pulled out. <IMAGE>
