Patent NL-7805515-A (NL)
Title: Clamp for internal gripping and centering of pipe ends - has hydraulic cylinders to expand elements radially onto inner pipe wall
IPC: B23K37/053
Filed: 1978-05-22
Abstract: The pipe clamp comprises a long frame with two fixing devices by means of which the outer ends of two pipes which are to be butt welded together are held coaxially during the welding process. Each fixing device consists of elements distributed around the axis of the clamp which move radially outwards against the inner wall of the pipe end. Each fixing device has its own hydraulic cylinder which serves as the actuator for this movement and is supplied with hydraulic fluid via passages within the clamp body and hydraulic hoses attached to connections on the back end of the clamp and passing through one of the pipes to the pump. The clamp may be used for a range of different pipe sizes. The device is relatively simple and robuts and enables a butt weld to be executed without interfering with the means of coaxially clamping the two pipe ends together.

Title: Pump with rotary vanes - has rotor and high pressure chambers connected by several ports offset in lengthwise direction
IPC: F01C1/34
Filed: 1978-08-03
Abstract: The rotary vane pump has two chambers connected via ports in their walls with the rotor chamber between them, in which the rotor is eccentrically mounted. Vanes sliding in slots in the rotor bear against the rotor chamber walls, and the connection to this chamber from the forst low-pressure chamber, which also has an inlet, is at a point where the volume between two adjacent vanes increases. The high pressure chamber, with an outlet, is connected to the rotor chamber at a point where this volume decreases. The connection between the rotor (2) and high pressure (4) chambers is formed by a number of separate ports offset from each other in the lengthwise direction of the rotor chamber. The low-pressure chamber can be similarly connected to the rotor chamber, the low-pressure ports being offset from the high-pressure ones in the lengthwise direction.

Title: System for separating floatable matter from fluids - esp. oil from ballast water, comprises separator followed by overspills(s)
IPC: B01D17/02
Filed: 1978-08-11
Abstract: The separator in a system for the sepn. of floatable matter from a fluid, is positioned higher than the point at which the fluid is drained away from a temp. storage vessel. The outlet side of the separator is connected to a conduit which may be an open channel, leading to the drain, and in which there is an overspill separating two sections of the conduit at different levels. This allows the fluid to fall through such a distance that the air necessary to give buoyancy to the matter which can be floated and which is still suspended in the fluid, can be taken up from the surroundings. Used esp. for sepn. of oil from the water from the ballast tanks of a transporter, for more efficient operation whilst using less energy.

Patent NL-7906442-A (NL)
IPC: H04N9/29
Filed: 1979-08-28
Abstract: A component consisting of two coupled PTC thermistors with the first thermistor having a lower cold resistance than the second thermistor and the first thermistor having a higher resistance at the operating temperature than the second thermistor. According to the invention, the electric connection to the second thermistor is made directly by solely mechanical contacts to the surface of the ceramic thermistor body. This means a considerable simplification during manufacture, as the second thermistor need not be provided with electrode layers.
Patent NL-8007093-A (NL)
Title: Coding and decoding digital data for transmission - comparing receiving coding key with internally generated key to achieve synchronisation before coded message is sent
IPC: H04L9/12
Filed: 1980-12-30
Abstract: The coded data are transmitted from a transmitting station (S) to a receiving station (R) via a communications channel (3), which may be a landline, radio link or optical fibre. The data generator (1), e.g. a teleprinter, is fed to a mixet circuit (4), where it is coded by the output of a pulse code generator (6), linked to a variable key generator (8). Before each transmission, the variable key signal is transmitted directly via a switch (9). At the receiving station, the incoming key signal is compared (12) with the output of an identical key generator (11), until the two signals are identical, but inverted and synchronised. At this point, the coded data is switched (10) to a pulse code generator (7) which decodes the original data and feeds it to the receiving machine (2).

Title: Urea synthesis from ammonia and carbon di:oxide - with common compressor for reactant and stripper off-gas
IPC: C07C273/04
Filed: 1981-09-01
Abstract: Prodn. of urea from NH3 and CO2 is carried out by (a) forming an aq. urea soln. contg. NH4 carbamate and NH3 at high temp. and pressure in a synthesis zone; (b) stripping the urea soln. with CO2 and/or NH3; (c) compressing the stripper off-gas and recycling it to the synthesis zone after partial or complete condensn.; and (d) isolating urea from the stripped soln. The improvement comprises using a combined compressor to compress at least part of the stripper off-gas and to bring one of the starting materials to the pressure prevailing in the synthesis or stripping zone, with the proviso that the last stage of the section in which the starting material is compressed and the separate stage in which the stripper off-gas is compressed are located in adjacent, mutually sealed compartments in a common housing. The compressor arrangement overcomes sealing problems.

Title: Piglet nipple system with horizontal pipe - has nipple union suction height corresp. to mean suction effort of piglet
IPC: A01K7/02
Filed: 1984-01-20
Abstract: A horizontal pipe is connected between a number of nipples and a liq. storage tank. The level in the tank is maintained by a float valve. Each nipple union is connected via a system of communicating vessels freely with the tank. The suction height is set to correspond with the mean suction effort of a piglet, this effort being limited by a guard plate. This prevents the animal taking the nipple too far into its mouth. A mechanism is also provided to prevent siphon effect after a piglet has let go.

Title: Arrangement for generating a torque
IPC: E05F15/02
Filed: 1992-12-17
Abstract: The invention relates to an arrangement for generating a torque on the driven shaft of the apparatus in which use is made of a hose which can be filled with a gas or liquid and, as it is being filled, changes in size in at least one dimension. This change is converted into displacement of a lever which transmits said displacement to an arm linked to the driven shaft and thus generates the torque. The device can be used, inter alia, in a hoisting apparatus (lifting apparatus) for a tailboard on a delivery van, the rotation of the driven shaft being converted into the movement of an arm of a scissor-type (pantograph) construction. <IMAGE>

Title: Method and apparatus for determining the flow velocity of a molten radiation-emitting material
IPC: G01F/
Filed: 1982-06-16
Abstract: Flow rate of a stream (1) of molten radiation emitting material is determined using the signals emitted by two radiation detectors (S1,S2) arranged to receive radiation emitted from a limited section of the material flow at two mutually spaced points along the flow path. Signals from the detectors are fed to circuits (ST1,ST2) which discriminate any pulse like variations (P) exceeding a given smallest amplitude and which are caused by the presence of gas bubbles in the material. A time measuring circuit (RC) measures the time interval between a pulse (P') occurring on the output of the upstream detector (S1) and the next occurring pulse (P') occurring on the output of the downstream detector (S2). A gating circuit (B) is provided in the output of the circuit (ST1) to block the transfer of a signal pulse occurring on the output of the upstream detector (S1) within a given time interval after the preceeding occurrence of a signal pulse of that output. Used for measuring a flow rate of molten glass ceramic or mineral materials. Provides a simple reliable measurement of flow rate without any physical contact with the stream of material.
