Title: Solder nozzle with gas knife jet
Inventor: ELLIOTT DONALD A
IPC: B23K1/08
Filed: 1993-03-11
Abstract: A solder nozzle to produce a smooth turbulent free solder wave has at least one air jet associated therewith to remove solder icicles and bridges that can form on the under surface of circuit boards and other elements. The circuit boards move in an upward inclined path in the direction of travel and after passing through the solder wave an air knife projects a non-oxidizing gas with sufficient force to remove excess solder. The soldering can occur in a non-oxidizing gas enclosure such as an inert gas, or a reducing gas, and vibrating the solder wave below ultrasonic frequencies can assist in the soldering.

Title: Magnetization of permanent magnet strip materials.
Inventor: BLUME WALTER S JR
IPC: H01F13/00
Filed: 1993-05-04
Abstract: Disclosed is an apparatus and process for magnetizing permanently magnetizable strip and sheet material to form a pattern of band-like poles on the material. Two parallel stacks of permanent magnets are used, each magnet in each stack having a direction of magnetization which is perpendicular to a slot-like air gap between the stacks. The magnets in each stack are parallel to one another, with unlike poles of adjoining magnets proximate so that they mutually attract one another. Unlike poles of the respective magnets in opposite stacks are positioned diametrically opposite each other across the air gap. The apparatus does not use electromagnetic coils and can form very narrow, contiguous band-like poles on magnetizable sheet or strip material which is passed through the air gap.

Abstract: The invention relates to a measuring system for scanning the surface of an object (7) to be measured by means of a distance sensor (1) which scans in a planar fashion. The sensor (1) and the object (7) to be measured are moved relative to one another. The extent (2) of the scanning surface of the sensor (1) in the direction (10) of movement is selected to be larger than the smallest extent (8) of the structure (9) which is still to be determined. With this proportion, the structure (9) is no longer reproduced at full size. In order nevertheless to obtain data on the extent (8) from this no longer correct information, the fraction of the output signal of the sensor (1) which is produced by the structure (9) on the surface of the object to be measured is integrated over the path of the movement. <IMAGE>

Abstract: A tire inflation pressure monitoring apparatus (10) comprises a reference magnet (15) fixed to a wheel (11), a movable magnet (16) whose position shifts depending on the inflation pressure of a tire (12), and a magnetic sensor (41) for detecting the magnetism of the magnets (15, 16). The reference magnet (15) can be moved in the axial direction of the wheel (11) by means of a position adjusting mechanism (2). Thus, a relative distance (D₀) from the reference magnet (15) to the movable magnet (16) can be adjusted to a fixed value (e.g., zero) at the time of calibration. An electric circuit section (50) is stored with a computation formula or a map indicative of the relationships between outputs of the magnetic sensor (41) and minimum distances (L₁, L₂) from the magnets (15, 16) to the magnetic sensor (41). In detecting the inflation pressure of the tire (12), data associated with the minimum distances (L₁, L₂) from the magnetic sensor (41) to the magnets (15, 16) are obtained according to the computation formula or map on the basis of the outputs obtained by means of the magnetic sensor (41). Based on these data, the inflation pressure of the tire (12) is obtained according to a pressure computation formula or a map indicative of the relationship between the tire inflation pressure and the distance between the magnets (15, 16).

Abstract: The invention relates to a stay 9 for holding a flap or a lid in a closed position or open position in relation to a container to be closed thereby. It has a first arm 9 and a second arm 10. These are intended to be fixed to the container and lid respectively by means of a pivot bearing. The two arms are connected to one another via a further pivot bearing. Active between the two is a compression spring 16 which supports the arms 9, 10 relative to one another in a position near to or remote from one another. For this purpose, the compression spring 16 is supported at one end 17 on the first arm 9 and at its other end 18 on the second arm 10, in such a way that, on the second arm, it is arranged eccentrically to the pivot bearing 13. In the extended position of the arms 9, 10, the engagement point of the compression spring 16 on the second arm 10 is offset to one side of a connecting line 27 between the centre point of the first pivot bearing 6 on the first arm 9 through the third pivot bearing 13 between the two arms 9, 10 and, in the position which corresponds to the closed position of the two arms and in which these are near to one another, the said engagement point is offset to the other side of the connecting line 27. This ensures a stay which is of simple design and which assumes a reliable holding-shut position, so that the holding-shut and holding-open forces can be predetermined exactly. The necessary forces for the closed position or open position can be achieved and predetermined in a simple way by exchanging the spring or by varying the support of the second arm relative to the first arm via the spring. <IMAGE>
