Inventor: SCHAUMBURG WILHELM
IPC: H01B13/02
Filed: 1990-05-30
Abstract: The invention relates to a device for the manufacture of stranded conductors by Roebel transposition of profile wires with a rectangular cross-section with a guide for the profile wires conveyed in two parallel stacks. The device is formed from side parallel guide surfaces and latches, which are offset through 90 DEG  with respect to said surfaces and one of which is provided per stack, the two latches being located diametrically opposite one another and being displaceable in parallel, in opposing directions, cyclically, and of slides which can move at right angles to the longitudinal extent of the stranded conductor for displacement in opposite directions of in each case one profile wire from a (lacuna) on the adjacent stack, while bending the profile wire. The slides are supported opposite one another in the other diagonal, in the same way as the triggers. The device furthermore comprises a control device for synchronisation of the cyclic operation of the drives for displacing the triggers and slides. The invention is characterised in that each slide (5) has allocated to it on the opposite side of the stranded conductor an opposing holder (8) which is offset with respect to the slide in the conveyance direction (9) of the stranded conductors and is supported displaceably in the opposite direction thereto, at right angles to the stranded conductors, and is driven in synchronism with the movement of the slides and triggers. <IMAGE>

Patent CA-2023677-A1 (CA)
IPC: G01P15/02
Filed: 1990-08-21
Abstract: An acceleration sensor includes a tubular bobbin only one end of which is fixed to a body whereas the other end is movable relative to the body axially of the bobbin, so that thermal expansion and shrinkage of the bobbin are not limited by the body.  Supported on the body are magnets for attracting a magnetic member, mounted within the bobbin, to a reference position.  A detection member is mounted around the bobbin so as to detect a displacement of the magnetic member from the reference position.  An acceleration sensing system incorporating such a sensor includes a processing circuit for processing an output of the detection member to output a detection signal representative of the direction and magnitude of the acceleration.  The processing circuit has a temperature compensation circuit for compensating for a variation of the output of the detection member due to a variation of the relative position between the magnet and the detection member in the direction of the axis of the bobbin, so as to keep the detection signal at a constant level when the acceleration is zero, the variation of the relative position being caused by a temperature variation.

Title: Method of brazing metal members
Inventor: KOGA NAOYUKI
IPC: B23K1/18
Filed: 1990-10-10
Abstract: A brazing method of joining a first metal member at an end portion thereof having a predetermined length to a second metal member formed with a bore having a straight portion and a tapered portion extending from the axially outer end of the straight portion and flaring axially outward. The first member is in a position between a horizontal position and a position inclined at 45 dgrees with a horizontal plane, the posi-tion of the first member including the horizontal posi-tion but not including the inclined position at 45 degrees.      The two members are joined by brazing with the end portion of the first member inserted in the bore straight portion of the second member through the tapered portion and with a brazing material placed around the first member axially outside the tapered portion. When melted for brazing, the brazing material flows axially inward as if it is drawn into the bore tapered portion of the second member around the first member end portion posi-tioned within the tapered portion, and further flows into and is retained in the bore straight portion around the first member end portion positioned in the straight portion, whereby the molten brazing material is prevented from flowing down.

Title: Spray drying process for making pharmaceutical powder compositions directly compressible into tablets
Inventor: KURAMOTO ROY
IPC: A61K9/16
Filed: 1990-12-21
Abstract: ABSTRACT OF THE DISCLOSURE The preparation of pharmaceutical powder compositions which are directly compressible into tablets, is disclosed.  The disclosed process includes subjecting an aqueous slurry/solution of a pharmaceutically active drug specifically naproxen or naproxen sodium (which slurry may be directly obtained without drying from the synthesis of the drug), alone or in admixture with an aqueous mixture of excipient materials, to a controlled form of spray drying to produce a dry powder of uniform particle size wherein the drug is uniformly dispersed in and coated with the excipients.  The powder can be readily combined with additional dry excipient materials and formed into tablets.  The process provides for substantial savings in the manufacture of the tablets.  The spray dried powder compositions are highly compressible.  Utilizing such spray dried powder compositions, the tablets formed are readily dissolvable and also are stable under normal storage conditions and stress conditions of temperature and relative humidity.
