Patent NL-8005540-A (NL)
Title: Fluid flow control system - uses time modulation control of pump or valve, esp. for burner of central heating installation
IPC: G05D23/20
Filed: 1980-10-07
Abstract: Conventional fuel systems and other processes using fluid controls such as needle valves and float valves suffer from the fact that the flow of fluid for one setting of the valve can vary with changes in temperature, viscosity, etc. This system uses a detector (2) which measures the actual effect of the fuel or other fluid on the process (1), and switches the supply of fluid on and off periodically. The detector signal is compared (3) with a reference (4) set by the operator, and the comparator output controls a timing system (5). The timing system controls the lengths of time for which the valve is fully open or closed. This control process is analogous to pulse-width modulation in the electronic field.
Patent NL-8020404-A (NL)
IPC: E21B7/12
Filed: 1980-10-31
Abstract: Gas, water and oil flowing out of an oil/gas well on a sea bed is collected using a vertical column which is lowered over the well to receive the oil/gas mixt. An oil column is built up in the column with an upper gas-filled portion. Oil and gas may be discharged from the column via respective outlets. The column may be operated at sea depths greater than 300 metres and in shallow water where it may be constructed as part of a platform. The interior of the column may be provided with horizontal webs which act as dampers to the upward motion of the oil/gas mixture. Oil and gas are separately transferred from the column to the sea surface for further treatment.

Title: Antigen or antibody labelled liposome contg. encapsulated enzyme - for rapid determn. of hormones, drugs, toxins and pesticides, esp. in food
IPC: A61K9/127
Filed: 1981-01-13
Abstract: Diagnostic agent (I) is an immunoreactive liposone labelled with an antigen or its cognate antibody, sequestering an enzyme having a signal to noise ratio of no less than 5. (I) is used together with a substrate for the enzyme, a test material and complement. The enzyme activity is detected by a colour change. The liposome may be prepared so described by Szoka and Papaliadjopoules in Proc. Nat. Acad. Sci. 75, 4194 4198/1978. Suitable enzymes include oxidoreductases, hydrolyses and lyases. Substrates for detecting the enzyme include p-nitrophenyl phosphate or 4-methylumbelliferyl phosphate or alkaline phosphatase 4-aminosalicyclic acid or o-diamisidine and hydrogen peroxide for peroxidases and o- or p-nitrophenylglycoside for glycosidase. Like radio-immunoassay the use of this reagent is rapid, but without the hazards of radioactive substances. It is also more adaptable than the enzume labelled antigen of prior art.
Patent NL-8203535-A (NL)
Title: Shop-lifting detector system - detects removal of EM nonlinear responders, but is not triggered by other metallic pieces
IPC: G08B13/24
Filed: 1982-09-10
Abstract: Each item in a shop has a small passive responder circuit attached to it, which can only be removed easily by the cashier. The transmitter/receiver aerials around the shop exit send two signals at slightly different frequencies (f1,f2) within the resonance band of the responder. A problem with conventional systems of this type is that they can be inadvertently triggered when metal objects, such as shopping trolleys, resonate within the responder band. To ensure that the alarm is triggered only by the responders, the present system uses continual synchronous shifting of the two signal frequencies (f1 to f3, f2 to f4), keeping the shifted frequencies within the resonance band of the non-linear responders.
Patent NL-8302369-A (NL)
Title: Training equipment for preventing sea-sickness - teaches subject to synchronise breathing with the movement of ship
IPC: A63B23/18
Filed: 1983-07-04
Abstract: If the ship rises and falls with a frequency close to normal breathing cycles an acceleration detector is linked to an audio-visual indicator, which shows a red light and sound a high tone when the ships starts to rise. As the ship starts to fall, a green light shows and a low tone sounds. The subject raises his shoulders, tightens his belly muscles and breathes in strongly on the rise signal; he relaxes and breathes out on the green signal. If the rise/fall frequency is too slow for direct synchronisation, breathing is synchronised to a harmonic of the actual frequency. After a short period of training, the subject is able to synchronise automatically without the aid of the indicator.

Title: Electronically-controlled fuel injection system for vehicle - varies effect of accelerator pedal to achieve optimum performance and uses Bowden cable
IPC: B60K31/02
Filed: 1983-07-14
Abstract: The sytem operates to prevent fuel wastage, while allowing the vehicle to be driven normally within preset limits. The accelerator pedal (7) is connected, via a system of levers (6, 5,4,3) a junction collar (8) and a Bowden cable (9), to the fuel supply valve (1) in the motor injection pump (2). The effect of the pedal can be enhanced or reduced by rotation of the Bowden cable. The cable position is set by a motor (10) via a screw coupling (11). The motor is controlled by an electronic unit (16). The electronic control unit is fed with signals from the vehicle alternator (14) and a tachogenerator (17). It compares demanded speed with actual speed and adjusts the Bowden cable between end stops (12,13).

Title: Temporary traffic sign fixture for motorway - fits on existing tube, with cam on plate engaging flattened part of tube
IPC: E01F9/669
Filed: 1984-01-09
Abstract: The sign, which may be placed along the central reservation of a motorway, can be quickly fixed to an existing vertical tube. The vertical tube is cut at one end at an angle of 45 deg., to facilitate easy insertion of the sign. The tube is welded to a vertical plate which is provided with three spaced cams. The centre fixture cam enters the aperture on top of the tube that a small clearance avoids jamming of the sign. The two outer cams prevent twisting of the sign. The sign may be replaced quickly by pulling upwards.

IPC: B01D61/00
Filed: 1987-09-09
Abstract: A membrane envelope (1) is spirally wound around a tube (4) provided with openings and the membrane layers of which are alternately kept at a distance from each other by retentate spacers and permeate spacers (2), which retentate spacers comprise relatively rigid rods or wires (3) extending parallel to the centre line of the module. In order to obtain a very constant and defined geometry of the retentate flow channels and a favorable ratio between membrane surface and module volume, the width dimension of the rods measured perpendicular to the membrane layers is 0.5 to 2.5 mm and the distance between the rods is 4 to 12 times said width dimension. Said width dimension of the rods measured perpendicular to the membrane layers should be at least three times the diameter of the largest particles in the liquid flow to be filtered.
