Title: Forming fringes on a high speed automatic towel loom - with electromagnetic coupling of main and auxiliary drives
IPC: D03D5/00
Filed: 1975-02-10
Abstract: Fringes are formed on an automatic loom equipped with an electromagnetic clutch, a patterning arrangement, frame uprights a reed, let-off motions and a take-up motion with a control system, the machine is stopped and a separate drive is coupled to the take-up motion. When the loop is stopped, the let-off motions for the ground warp and the loops are disengaged, the shed is closed and the reed is positioned at its forward dead point. Control is effected by an electronic circuit, the number of turns made by the auxiliary drive of the take-up motion being counted and compared with a registered nominal value for the length of the fringe. When this figure is reached, the auxiliary drive is disengaged and the reed brought to its backward dead point, before weaving is restarted. Fringe is obtd. without any picks at all. Difficulties of stopping the machine at high speed with the risk of breakages, or of speeding up the take-up motion and imposing higher loads on the warp is overcome without expensive and complicated servo mechanisms.

Title: Hydrodynamic pump shaft seal - uses pumping action of opposed helical grooves in push on shaft to circulate sealing liquid via external cooler
IPC: F16J15/40
Filed: 1981-03-03
Abstract: The shaft seal comprises a fixed bush (7) inside which a bush (10) on the shaft (4) coaxially rotates. The annular space between these bushes contains a sealing liq.

Patent NL-8403534-A (NL)
IPC: G11B7/095
Filed: 1984-11-21
Abstract: The apparatus ensures that locking-in to the track (25) of a record carrier (1), for example a compact disc, is effected at the most eccentric point (28) of a circle (27) described by the light spot P, which is projected on the record carrier by a light beam via an objective system (8), when the record carrier rotates and the objective system is stationary. In this point the relative radial speed of the light spot P with respect to the track is minimal, so that locking-in can be effected in the simplest way at this instant. 
<??>The radial positioning means (77) are switched on at this instant under the influence of a first control signal (S1), which is applied to a lock-in system (78). 
<??>Moreover, locking-in to the track at this most eccentric point (28) has the advantage that even if the objective system is in its initial position, which means substantially against the stop it remains possible to follow the track even atter the first complete revolution of the record carrier after locking-in so that no loss of track occurs. This would be possible in the case of locking-in to the track of an eccentric record carrier at a point other than the above-mentioned point.

Patent NL-9101880-A (NL)
Title: Driven slide system
IPC: B66C9/14
Filed: 1991-11-11
Abstract: Linear guide system in an appropriately matched rail. The system is such that it seals itself against the penetration of dirt by lifting a toothed belt which is used for drive purposes out of the rail when a carriage running through the rail moves past and pushing this belt back into the rail after the carriage has moved past, by means of rollers which are mounted on the carriage. In this way, the carriage running through the rail automatically seals the rail with respect to dirt as it moves past.
Patent NL-9402125-A (NL)
Title: Lens-clamping fixture and clamping method
Inventor: DRUTEN ROELL MARIA VAN
IPC: B23Q3/08
Filed: 1994-12-13
Abstract: The invention relates to a clamping fixture which allows a plastic lens which is to be clamped on both sides to be machined on a precision lathe. Concentricity and rotational deviations arise both when transferring the lens material to another holder using wax and when fixing the holder on the spindle of the precision lathe using a screw-thread securing means. Also, in an existing system the abovementioned operations have proven difficult to automate. In addition, there is no wish to clean the holders which are covered with a wax like substance. The object of the invention is to keep the tolerances for the abovementioned concentricity and turning deviations within one micrometer for a lens with a diameter of approximately 10 millimetres, and to eliminate the need for a cleaning agent for removal of the wax. To this end, the invention provides for the lens material to be secured between three balls which are at equal distances from one another and are fixed to one another in a mount with V-grooves on the spindle of the precision lathe, and for the lens, after it has been machined on one side, to be fixed within the actual lens material using wax. No wax comes into contact with a component which is to be reused. There is no need to transfer the lens material onto another holder, and the same three balls are used to centre both sides of the lens material. The invention facilitates automation of the clamping operation, since the clamping fixture is self-centring. In addition, the need to clean holder(s) which have come into contact with wax is eliminated.
