Title: Colouring plastic articles - by adding dye to the melt in the extruder
IPC: B29C48/29
Filed: 1972-04-10
Abstract: Granulated, pref. colourless, thermoplastic material is supplied to a melt chamber where it is heated to produce the melt, and measured quantities of dye are supplied to the melt chamber and mixed with the melt pref. using a paddle, the melt then being fed to an extrusion head by a screw feed.

Title: Variable-stroke pump - has adjusting wedge piece spring-loaded against supporting surface
IPC: F04B49/12
Filed: 1974-08-13
Abstract: The pump has inlet and outlet valves and a chamber accommodating a compression plunger, whose stroke is variable by a mechanism incorporating a wedge piece.

Title: Gear ratio change control system - uses transducer to provide output torque signal to effect gear ratio change
IPC: F16H59/16
Filed: 1977-05-27
Abstract: The control system is used to change the gear ratio in a gear set regulated by a change-gear signal from a control unit. A transducer provides an output torque signal which is compared to other signals for initiating the gear change. Alternatively, an automatic transmission changes a gear ratio when engine torque is transferred from one member to another member of a three member planetary gear set. The transfer is accomplished through friction elements engaged by hydraulic pressure. A closed loop electrical circuits is completed between a transducer, which provides an electrical signal related to the output torque of the transmission, and a control valve, to vary the control valve pressure. A circuit for computing reaction torque is coupled between the transducer and a logic control circuit.

IPC: C09D127/08
Filed: 1977-10-25
Abstract: Films of biaxially oriented polypropylene have a heat-weldable coating consisting essentially of an interpolymer of (a) 5-15% by wt. of a mono-ethylenically unsatd. acid chosen from methacrylic acid and its mixts. with acrylic acid, (b) 50-85% of vinylidene chloride and (c) 5-45% of an alkyl acylate selected from Me, Et, Bu, iso-Bu and octyl acylates. It may also contain 0.1-1.0% by wt. of an anti-adhesive agent insoluble in water and consisting of finely divided particles measuring 1-5 mu. This is a finely divided wax or a material such as talc, silica, clay, mica or a PVC resin. The compsns. enable films to be heat-welded over a wider temp. range and at a lower min. temp., ad also increase the resistance of the films to the transfer of gases. The coated films have excellent optical properties. Interpolymers contg. 75-85% vinylidene chloride give films having sufficiently low viscosity to permit their use in automatic packaging machines.

Title: Ammonium hepta:molybdate prodn. - by extracting molybdenum tri:oxide concentrate with water and ammonia
IPC: C01G39/00
Filed: 1978-01-12
Abstract: Prodn. of (NH4)6Mo7O24.4H2O (I) comprises first leaching a MoO3 concentrate in H2O at 70-95 degrees C (solids content 5-50%) for a time sufficient to extract at least part of the contaminating metal ions into the aq. phase. The leached concentrate is then sepd. from the aq. extract, and soluble molybdates are recovered from the latter. The leached concentrate is then leached with NH4OH soln. to extract NH4 molybdates, and the extract is sepd. from the insoluble residue and concd. in an evaporator to form a satd. soln. of NH4 molybdates. The satd. soln. is (partly) withdrawn and adjusted to a NH3:MoO3 molar ratio of 0.86-1.25:1, and is then cooled to ppte. crystals of (I). These are sepd. from the mother liquor, which is recycled for mixing with a fresh batch of ammoniacal extract entering the evaporator. (I) is used as an analytical reagent, for the prodn. of pigments and catalysts (e.g. for petroleum refining and coal treatment) and for the prodn. of metallic Mo. The process does not require a purified MoO3 starting material, air-roasted molybdenite concentrates are suitable.

Patent NL-8020187-A (NL)
IPC: D21F1/48
Filed: 1980-05-20
Abstract: Web of paper is formed in a space enclosed between an upper flexible lip extending from the straight edge nozzle of a slurry feed box, and a part of the woven metal gauze which is not supported, at least at the end of the forming of the web, in a fourdrinier machine. At the same time, the extraction of the water from the slurry takes place under the action of a vacuum. The vacuum is maintained unaltered after the formation, whilst the web of paper remains on the unsupported section of the gauze. Used to eliminate as far as possible, in a fourdrinier machine, the incorrect laying down of the web of fibres due to excessive turbulence above, or to upwards pressure on the gauze from below. The technique deadens the hydrodynamic disturbances and makes it possible to maintain uniform solidity and superficial weight. A greater amt. of water can be extracted, so that the metal gauze section can be shortened in length.

Patent NL-8104879-A (NL)
IPC: A61B5/02
Filed: 1981-10-28
Abstract: Arrangement for controlling the cuff pressure in the indirect, non-invasive, continuous measurement of blood pressure in a finger by using a photo-electric plethysmograph in a fluid-filled pressure cuff, an electronic control circuit and an electric pressure valve, the cuff pressure being controlled by the plethysmographic signal in closed-loop operation by means of a servo-reference level, so that the arterial volume is maintained at a pre-adjusted value. For initial adjustment, the cuff pressure or the servo-reference level as initial adjustment quantity is automatically changed continuously in the control range by means of a control waveform supplied to the electronic control circuit, that thereby the peak-through amplitude of the pulsatile plethysmographic signal or cuff pressure signal is detected time and again, and compared with the preceding peak-through amplitude. The biggest value thereof in the control range and the associated value of the cuff pressure at servo-reference level are stored, which value of cuff pressure or servo-reference at the end of the initial adjustment is used as set value for the measurement of the blood pressure.

Title: Inducing superconductivity in substances at above 20 deg K - by artificial introduction of electrons into the material, e.g. into the outer electron shell of elements
IPC: H01L39/24
Filed: 1984-01-27
Abstract: A method for inducing superconductivity in substances at temps. of above 20 K comprises (1) selecting the material to be placed in the superconductive state on the basis of the super-ionisation theory and the chosen application, (2) selecting the most suitable means for inducing superconductivity at temps. of above 20 K on the basis of the technical facilities available and on economic consideration. The essential step is the artificial introduction of electrons into the electrically insulating material, supplemented by lowering of the temp. or press and/or increasing the surface area. Superconductivity can be induced in liquids by atomising the liq. in an electrically insulating ionisation chamber under low press. and temp. and simultaneously exposing to slow electron radiation or a high voltage field. Subsequently the mist is converted into a superconductive liq. by raising the press. without raising the temp.
