Patent NL-7405823-A (NL)
Title: Liq. ion exchange treatment appts - with automatic regeneration when resin contracts on exhaustion
IPC: B01J49/00
Filed: 1974-05-01
Abstract: Appts is partic. intended for the softening and demineralisation of water and for the removal of undesirable colour or odour. It comprises brine reservoirs, a water treatment tank with the inlet for the untreated water and an outlet for the purified water, a treatment cartridge inside the body and a movable support for this cartridge, mounted on springs. The cartridge contains the ion exchange resins which contract as they become exhausted; the cartridge contracts in length and the relaxation in press. on the supporting plate starts the regeneration process. After a rinse, the resin again comes into operation and the flow of water to be treated is resumed. The regeneration is started simply by liq. press. and does not depend upon electrical or mechanical means.

Compared with existing designs, the arrangement is more compact and gives a greater driving force.
Patent NL-7614289-A (NL)
Title: Synthetic foam profiles prodn. with uniform cross=section - using two: zone mould with plunger and retractable wall
IPC: B29C44/20
Filed: 1976-12-22
Abstract: Objects of synthetic foam having a constant cross-sction over the whole of their length are produced in a mould cavity of corresponding cross-section. The cavity is open at one end and at the other is closed by a plunger which is displaceable in the lengthways direction of the mould. The mould cavity is filled with thermally expandable material which is heated and allowed to expand. The product formed is ejected by the plunger through the open end and the plunger is retracted for the cycle to be repeated. The mould cavity has flat walls and at least two of the side walls retract from each other as the product is ejected. After ejection they reapproach. The mould is continuously heated externally to immediately below the temperature at which expansion occurs, and after filling each time, steam is blown in to raise the temperature above this level. Only that part of the mould in which the plunger moves is heated. The other zone may be cooled. Foamed products have smooth surfaces. By retracting the walls the need for excessive pressure during ejection is obviated.

Title: Lorry body folding sideboard - has upper hinged section linked by bars to uprights
IPC: B62D33/03
Filed: 1978-12-21
Abstract: The folding side- or tailboard is for a lorry body, and is in two or more parts (1, 2) hinging together (3). The lowermost one hinges at its lower edge at or near the level of the load platform (5), while the uppermost one is linked by bars (6) attached to its upper edge to the uprights (9) on the body. In the shut position, all hinges and pivot points can lie in a vertical plane, while when open the two parts lie against each other. The uprights can be pivot-mounted on the chassis. The design allows the height of the boards enclosing the load to be increased without them fouling the ground when let down.

Title: Water wheel using troughs attached to endless belt - has two rollers rotating by water power with axle of one coupled by gearing to generator
IPC: F03B9/00
Filed: 1979-07-31
Abstract: The water wheel has an endless belt assembly, revolving around two rotatable rollers (3,4) fitted to horizontal axles (1,2) mounted one above the other at a spacing adequate to fully extend the belt. The belt has horizontal cross-members (8) each equipped with wires to retain a long trough (9), open along one broad side and closed along the opposite narrow side. When positioned under a duct of flowing water (11), the troughs (9) fill with water and the additional weight causes the belt to rotate, as each trough empties as it turns through the lowest point. The axle (1) through the upper roller is connected to a gearing block (6) and a generator (7).

Patent NL-9100816-A (NL)
Title: Hollow plastic structure-reinforcement method - by joining sections by inflating and hardening adhesive auxiliary plastic structure
IPC: F03D1/06
Filed: 1991-05-10
Abstract: The method reinforces a hollow plastic structure, of which two sections are first produced, the inner surface of each being accessible. An inflatable auxiliary structure of unhardened plastic is then produced, and which can adhere to the inside surfaces of each of these sections. The latter are then assembled together with the auxiliary structure between them, and this is pressed by inflating against the inside surfaces. The pressure is maintained for the time necessary for the auxiliary structure to harden and adhere to the sections, which are finally joined together after a further period if necessary. A flexible net can be fitted round the auxiliary structure, protruding through the seam to the outside, and held so that it cannot move inwards. The structure can be filled with foam material while under pressure.

Patent PT-75245-A (PT)
IPC: H03K17/60
Filed: 1982-07-14
Abstract: A series connection consisting of a diode and one of two transistors of a transistor push-pull circuit is connected in parallel to the feed current path for a light-emitting diode and a capacitor is interconnected between the junction of the push-pull transistors and the junction between the light-emitting diode and an additional diode which is present in the feed current path. When the transistor in the series connection is in a blocking state, the light-emitting diode receives feed current and is thus switched to a light-emitting state. The capacitor causes a current pulse to be superimposed on the feed current during switchover for rapidly driving the light-emitting diode by decreasing the time span required by the light-emitting diode to reach a condition of maximum light emission.

Title: Regenerator for oxidation and cleaning of a liquid
Inventor: LARSEN BJARNE R
IPC: C02F1/32
Filed: 1996-03-08
Abstract: The invention concerns a method for the oxidation and cleaning of aqueous environments ranging from lakes and streams to swimming pools. The invention also concerns a device for the practice of the method as well as the use of the device. The invention consists of a reaction vat (1) for submergence in liquid (100). In the reaction vat (1) there is a rotor which causes a downward rotating current in the reaction vat. Above the reaction vat (1) a mixture of ozone and UV-irradiated liquid is conducted and is in turn sucked down and mixed with the liquid that is to be conditioned during the rotating downward current. The invention can be used for the oxidation and disinfection of both sensitive biological environments such as lakes, streams, etc., and less sensitive environments like swimming pools and the like, since the conditioning ozone can either be ozone produced using UV-irradiation or so-called high tension ozone, also known as corona ozone.
