Title: Braking system for roller ski - has hinged shaft with crossbar forced back by calf pressure against rear ski wheels (OE250875)
IPC: A63C17/14
Filed: 1975-08-25
Abstract: The braking system for a roller ski consists of a shaft (18) which is hinged on an axle (20) in a hole in the ski stem (10). A braking bar (22) is fitted to the lower end of the shaft (18) and consists of a cross bar which contacts the outer edge of the wheels (14) to bring them both to a halt. At the top of the shaft (18) is a curved cross bar (24) level with the rear of the skier's calf. When the skier wishes to halt, the leg is brought upright forcing the calf (25) against the upper cross bar (24) swinging the shaft back so that the brake bar (22) contacts the rear wheel. The shaft is returned to the running position by means of a rubber block fitted to the ski platform (10) behind the shaft (18). The front edge (19) of the hole in the stem (10) limits forward movement of the shaft. The shaft can be dismantled into two pieces for transporting the skis. This method provides a ski brake which allows the skier to brake without losing balance and without having to fit ski poles into the brake arms, which may not be possible in an emergency.

Title: Oxidn resistant flexible polyurethane foam - by reacting normal components in presence of organo tin cpd as gelling catalyst
IPC: C08G18/24
Filed: 1976-04-09
Abstract: Flexible cellular polyurethane is prepd. by reacting (1) a polyol contg. >=2 active H atoms per mol. as determined by the Zerewitinoff method, with (2) a stoichiometrical excess of a polyisocyanate, in the presence of (3) a blowing agent, and (4) of a gelling catalyst of formula: R'aSnX4-a, (R'3Sn)2S, (R3'SN)-2-(OC(O) C(O)O)-, R'2SnS, (R'Sn-(OC(O)CH=CHC(O)O)-or (R'3Sn)2-(OC(O)CH=CHC(O)O)- (where R' is methyl, allyl, benzyl, (substd.)phenyl, or benzyl, X is Cl, Br, -S-CO-NR22. -SR3, -SCnH2nC(O)OR3, or -OC(O)R4, R2 and R3 are each 1-20C alkyl, cycloalkyl, phenylalkyl, alkylphenyl, or phenyl, R4 is 1-20C alkyl, cycloalkyl, or (substd) phenyl, a is 1,2 or 3, and n is 1-12). The process gives cellular polyurethanes with a better resistance to oxidn. and heat, the flexible cellular structure maintaining its integrity and resilience for long periods. The cpds. have practically no effect on the foaming process, or the physical properties, esp. resilience of the foams.

Title: Vehicle central lubricating system - has servo operated pump controlled by switch coupled into tachometer cable
IPC: B60R17/02
Filed: 1977-06-14
Abstract: The central lubrication system is operated by a servo pump powered by the vacuum or pressure levels in the vehicle. The vacuum or pressure reservoir is separated from the pump by a dosing control valve linked to the tachometer. This provides metered amounts of lubrication in relation to the distance travelled. The dosing valve is coupled to the tachometer by cutting the cable drive and inserting both ends into the valve. The system can be fitted to any vehicle, with either vacuum or pressure pump. The tachometer function is not affected, while the dosing valve can be fitted to any convenient position on the cable.

Title: Two-zone activated sludge tank to purify waste water - offers high efficiency treatment by repeated inter-zone transfer for intermittent aeration
IPC: C02F3/12
Filed: 1979-01-04
Abstract: The tank is of the type in which the water is agitated by an aerator, e.g. a rotary impeller, The aerator is surrounded by a partition enclosing an inner zone of liq. and an annular outer zone of liq. is held between the partition and the outer wall of the tank. A passage is formed through the partition at or near surface level and another passage at or near tank base level. The aerator creates a flow of liq. through a passage from the inner zone to the outer zone. The transferred liq. circulates around the outer zone before finding its way back to the inner zone via a different passage. The passages are pref. formed and positioned and related to the direction of rotation of the aerator so that flow is outwards from the inner zone via upper passages and inwards from the outer zone via lower passages. The tank is pref. of vertical cylindrical form with a coaxial, vertical cylindrical partition around a central aerator. The treated effluent can be equal to that delivered from the conventional 3-stage process, i.e. free of ammonia and probably nitrates too. For such effective treatment the new plant is very compact and inexpensive.
Patent NL-7903931-A (NL)
Title: Removal of gas bubbles from lacquer on carrier - esp. paper or PVC film by suction box
IPC: B05D3/04
Filed: 1979-05-18
Abstract: After the application of a thin layer of viscous material to the web of a continuous carrier, the web is led through a zone of reduced pressure to remove gas bubbles from the layer. The process is of value in particular for the treatment of a layer of lacquer deposited by screen pringing techniques on a continuous web such as paper or PVC film. After printing the web is drawn through a slit between two suction inlets arranged opposite to each other. The layer of viscous material is heated either before entry or when it has entered the zone of reduced pressure. For use in processes for the application of a coating of lacquer to carriers for packagings, floor coverings, etc., so as to improve the sheen or the resistance to abrasion. The removal of the air bubbles eliminates the pin hole effect on the surface of the product. Not only are the air bubbles removed, but by setting up a flow of air across the layer, the surface of the lacquer is smoothed without the danger of striping. At the same time, noxious vapours are prevented from escaping into the atmosphere.
Patent NL-8103438-A (NL)
Title: Fuel control circuit for vehicle engines - reduces fuel flow at high revolution notes, if throttle is closed
IPC: F02M3/045
Filed: 1981-07-21
Abstract: When a motor-vehicle engine is operating at high speed, but the throttle is closed, as happens during braking, fuel is sucked into the carburettor and wasted. This circuit reduces the flow of fuel to a 'tick-over' min. when the accelerator pedal is not pressed, but the revolution rate is high. The vehicle ignition signal (2) is fed via a 0.25 second differentiator (1) to a comparator circuit (6) where the rate is compared (5) with a reference signal. If the throttle microswitch (11) is operated, i.e. no foot is on the pedal, the output amplifier (8, T1) operates a valve (9) reducing the fuel flow and lighting an LED (10) on the dashboard.
Patent NL-8105097-A (NL)
Title: Sheet treatment method before underwater installation - secures in folds to give additional area adapting to supporting surface
IPC: E02B3/12
Filed: 1981-11-11
Abstract: The pre-treatment method is for clotch, sheet material etc. to be laid underwater, this being folded or rucked together before installation. Thus even when placed in position and stretched taut over the supporting surface it has a sufficient additional surface area to adapt to unevenness in the latter. This can be done by attaching threads between fixing points at regular intervals on the material and pulling the points towards each other. On installation, the thread either breaks under the tension load or dissolves after a time underwater. Alternatively a series of folds can be formed, intersecting at right angles and held in place by glue or threads likewise dissolving in water.

Patent PT-74465-A (PT)
IPC: H01H9/04
Filed: 1982-02-19
Abstract: A fleece is employed for the distribution of casting resin over a component surface to be sealed. Prior to the introduction of the casting resin, pressure is applied on the fleece with a heated stamp in order to smoothen the fleece. Through increased temperature of the stamp, or through a solvent, the fleece can be readily cemented together with the component surface. It is thus ensured that the fleece rests uniformly on the entire component surface to promote a favorable distribution of the casting resin.

Filed: 2001-09-28
Abstract: An open-ended mold for casting metal strands with a thin slab cross section, the mold having broad-side walls which form a central widening region which extends from the mold inlet edge to the mold outlet edge and at the outlet edge opens out in a rectangular outlet cross section. To prevent to a great extent the strand from coming away from the broad-side walls, the contour of the mold cavity in the widening region is formed, as seen in sectional planes taken at right angles to the longitudinal axis of the mold, by curves which at least in partial regions form clothoids or clothoidal curves, within which sudden changes in curvature (Deltak) are minimized or reduced to zero. The curvature reduces to flat at the mold outlet edge. Other cavity surface features are disclosed.
