Patent NL-7714395-A (NL)
Title: Pipe socket with internal sealing ring - providing a flexible joint which obviates reinforcement; thus reducing cost
IPC: F16L47/08
Filed: 1977-12-27
Abstract: The socket has section which grips the pipe and an internal groove for a sealing ring. The end of the socket has a larger internal dia. than that of the zone of the sealing ring, and a collar in one or more pieces is pushes into the annular cavity between socket end and pipe and glued in place. A socket connection for pipes of synthetic material makes a force joint capable of withstanding tensile loading without reinforcements which in difficult terrain may be expensive.

Title: Offset printing plate cleaning device - comprises retractable knives moved by electromagnet and locked by remote control
IPC: B41F35/06
Filed: 1978-12-06
Abstract: The equipment removes foreign bodies from offset printing plates, and comprises a retractable knife (6) in the path of each of the plates (1-4) printing the different colours. Each knife is movable sideways in relation to the plate and parallel to its axis of rotation, its width being at least equal to the band of ink metered by one of the inking valves. The knife locking positions can each coincide with one of the valves, it being typically controlled by an electric magnet causing it to rub against the plate or move clear of it.

Title: Inductive heating and demagnetisation of roller bearing - is connected as sec. winding of transformer circuit with variable inductance in primary
IPC: H01F13/00
Filed: 1979-01-08
Abstract: An inductive heating and demagnetisation system is described where the object is placed in an electromagnetic alternating field until it reaches the required temperature. The bearing is ring-shaped and forms the secondary winding around the yoke of a transformer. The current is supplied to the prim. until the required temp. is reached. The alternating current is reduced gradually to zero when the ring has reached the required temperature. This will prevent the formation of the residual magnetism. The primary circuit of the transformer contains a variable choke. It consists of a coil with a core of magnetisable material with a winding. The alternating current is reduced by increasing the value of the variable self-inductance.

During penetration of the sea bed, the soil (4) is displaced through a tunnel of constant sectional area. The shank legs make an angle along their length of 0 degrees plus or minus nine degrees with the fluke axis. The straight penetration position is maintained by stabilisers (11) at the rear corners of the fluke (3) each consisting of a side-ways offstanding earplate which stands at a forwardly opening angle.
Patent NL-8201229-A (NL)
Title: Ground tube insertion method - uses lengthwise protrusion on wall forming annular space during rotation
IPC: E02D7/26
Filed: 1982-03-24
Abstract: The method inserts a tube in the ground, the tube (2) having an end with a cutting edge and being rotated as it is driven home. One or more protrusions (4) on the side of the tube wall extend from the cutting edge (3) towards the other end for a distance at least equal to that for which the tube is to be driven into the ground (1). As the tube is driven home, this protrusion forms an annular space (21,22) at the side of the tube. On at least one side of the wall the protrusion can run continuously from the cutting edge to the other end.
Patent NL-8203169-A (NL)
IPC: F02D19/08
Filed: 1982-08-12
Abstract: A system for use of gas, like LPG, as secondary fuel in diesel engines is concerned. Normally aspirated and pressure charged engines with exhaust gas driven charging, with End-speed or All-speed governors or with common-rail-fuel injection systems are all included. A signal (24,25) proportional to the momentary effective fuel consumption controls the gas supply (20) to the engine (1). A valve (19) in the gas supply (18) is connected to the control lever (16) of the engine governor (12) to allow gas supply only in a load range above approximately 25% and up to a maximum of approximately 40% of the full load total fuel consumption. In the lower load range uncomplete combustion of the gas thus is avoided, in the higher load range both detonation and overload are avoided and the opacity of the exhaust is improved. The consumption of liquid fuel is reduced and the exhaust gas composition is improved. An adjustable stop (28,29) limits the maximum injectable liquid fuel quantity when the engine is operated in the dual-fuel-mode. The system is designed to be both retrofittable to existing engines and fittable to factory new engines.
Patent NL-8300213-A (NL)
IPC: A47J31/06
Filed: 1983-01-20
Abstract: Apparatus for brewing, in particular, a multiplicity of consumption units of a hot drink, such as coffee. The apparatus comprises a combination of a filter pan and a disposable filter cartridge with cellulose web filters. According to the invention, the filter cartridge and the filter pan have parts cooperating to provide a circumferential seal, dimensioned so that when introduced the filter cartridge rests loosely in the filter pan without being clamped therein, and a seal is provided by means of capillary forces that occur during brewing in the gap between the cooperating parts. The filter cartridge may have axially symmetrical body, and the parts of the filter pan and the filter cartridge co-operating to provide a seal may have a substantially equal axially symmetrical conicity.
Patent NL-8501357-A (NL)
Title: Sandy sealed loosening system - forms ribs with teeth of roller in suction dredger head
IPC: E02F3/92
Filed: 1985-05-13
Abstract: The system converts a solid sandy seabed into a loose one by hauling over it a suction dredger head, in whose mouth is a notching roller parallel to it. A pattern of loosened sand ribs is formed by the imprint of the roller teeth (25) in the area enclosed by the head (3), these running at right angles to the current of water directed over them. The water thus flows over the increased surface area generated, the sand being lifted free and transported away through the suction pipe (4-7).
Patent NL-8700398-A (NL)
Title: Down-the-hole step=down gear - with overload and drilling fluid access protection and self-aligning bearings (NL 11.7.79)
IPC: F16H57/08
Filed: 1987-02-17
Abstract: A step-down gear between a hydraulic turbine and the drill bit at the bottom of a well includes a device which prevents an overload. The input and output bearings of the gear are self-aligning two-row roller bearings. Seals on the bearing side away from the gear are fitted with a separating cavity filled with a buffer solution. This permits a greater torque and a slower speed of the drill bits so that optimum drilling conditions can be achieved by an exchange of the gear unit.

Patent PT-75004-A (PT)
Title: Directed flow layer glass fusion process
Inventor: ALEXANDER JOHN M
IPC: C03B5/235
Filed: 1982-06-03
Abstract: Discrete bodies of glass-forming raw materials are formed by agglomerating techniques such as briquetting. These bodies are preheated or prereacted using waste heat from the fusion furnace. The hot glass bodies are charged to a refractory hearth heated to a temperature substantially above the temperature at which the glass product becomes fluid. The discrete bodies absorb heat, form a liquid phase and lose their morphology. The hearth is structured so that the liquid phase flows through it in a thin layer entraining any unreacted/unmelted material. As the molten material flows it is further heated and the reaction is completed. Molten glass product can be drawn from the hearth in a surprisingly short time after charging the heated discrete bodies to the hearth.
