Patent NL-7114506-A (NL)
Title: Oil removal - from water surfaces using particles of inert material with hydrophobic surface obtained by heating resin coating
IPC: C02F1/68
Filed: 1971-10-21
Abstract: Particulate material for removing oily material from water surfaces consists of particles of an inert material coated with a carbon-contg. oleophilic and hydrophobic layer formed by applying a resinous coating material and then heating the coating. The particles attract and retain a relatively large volume of oil. The resinous coating material is pref. mixed with a hydrocarbon or vegetable oil. The inert material is pref. sand, and the resinous coating material is polyethylene or polyvinyl acetate. The wt. of each inert particle is suff. to cause the coated particle to sink in water. The coated particles are heated at 288-538 degrees C. The gases released during the heating of the coated particles are burned.

Title: Conveyor system with rollers sliding over drive shafts - controlled to stop one line of products while others continue on same conveyor
IPC: B65B43/52
Filed: 1973-06-26
Abstract: Transporter has two basic sets of rollers each set moving at different speed. Each roller consists of a driven shaft over this shaft a number of independent rollers are fitted with little clearance. These rollers are the actual means of transport. If e.g. a container is placed on top of this roller, the weight will cause increased friction between roller and continually driven shaft, which causes the container to be moved. If for any reason the container is blocked, then the friction between roller and shaft is not large enough and roller will freewheel over shaft. Since there are numerous rollers on each shaft, the next container, standing on the same shaft may be forwarded.

Title: Highly thermally and mechanically loaded pipe joint - includes well-fitting collar reducing breakdowns due to excessive stress
IPC: B01J19/00
Filed: 1979-06-27
Abstract: Collar for regulating thermal and mechanical stresses is incorporated in a connection between a first and a second component which are exposed to high temp. The collar consists of a tube which is fitted over and fastened to one end of the first component. Its internal dimension is such that it fits closely over the first component, and it is of the same material as the first component so that differences in thermal behaviour between the two are avoided. The inner edge of the free end of the collar has a smooth contour. Used for the control of the tensions in a mechanical connection subjected to movement and high temp. The invention is esp. applicable in steam-methane reformers for the production of hydrogen gas' and concerns the attachment of the small tubes delivering from the catalyst tube to the outlet collector manifold. The collar reduces the breakdown of mechanical connections due to stress, and also reduces breakdown in the welds following thermal fatigue and granular limit oxidn. The collar does not reduce the stretching limit of the material in the zone attacked by heat and it increases the reliability of welded connections.

Title: HV detector probe using multivibrator and indicating LEDs - detects the presence of AC potentials greater than one thousand and has in built test facilities ensuring it is serviceable before use
IPC: G01R19/155
Filed: 1981-03-17
Abstract: The voltage on the probe needle is amplified and used to hold the state of a multivibrator constant. The non-inverting output is amplified to drive a red light-emitting diode, LED. If no voltage is present, the inverting output drives a green LED via another amplifier. If the needle is not pressed into the body of the probe, an a.c. generator causes the LED's to flash alternately. When, as a test, the needle is pressed in with a finger, the green LED lights. If the finger is then used to short together the needle and an auxiliary electrode, the green LED goes out and the red one lights, due to a signal from another a.c. generator.

Patent NL-9301003-A (NL)
Title: Fire-resistant sliding door, substantially composed of cellular concrete, with a sliding rail system which in the last stage of the sliding motion presses the door leaf against the wall, the speed of the closure movement being limited by the sash weight being provided with a piston
IPC: E05F1/02
Filed: 1993-06-10
Abstract: The invention relates to a fire-resistant sliding door which is substantially composed of cellular concrete (foamed concrete, porous concrete, gas concrete), the door leaf thereby remaining flat when heated on one side (unilaterally). As a result of a special rail system being used, the door leaf in the course of the closing movement slides tightly against the wall, thus achieving good flame-tightness without the use of additional, expensive labyrinth seals all round. At the same time, the necessary braking of the closing movement can be carried out without an expensive apparatus by employing a simple washer against the bottom of the counterweight (as with a bicycle pump) and a controllable throttle valve at the bottom of the weight box.

Title: Automatic brake control system
IPC: F16D/
Filed: 1984-07-17
Abstract: The automatic brake controller comprises a body with a passage for the brake fluid and valves mounted in the body to control the passage of the fluid, these valves comprising a main and secondary valve. Two electromagnets are mounted at opposite ends of the body to selectively actuate the control valves, and an electric circuit selectively excites the electromagnet coils. The electromagnets can be activated to vary the brake pressure, particularly during starting on slopes, and the electric circuit associated with the controller correctly switches the brake lights. Microswitches on the clutch pedal operate the electromagnets, with handbrake contacts connected in series to passivate the system while the vehicle is stationary.
