Title: Disk drive having an electrically isolated disk stack
Inventor: MC ALLISTER JEFFREY S
IPC: G11B33/14
Filed: 1990-08-09
Granted: 1994-09-20
Abstract: A disk drive in which the rotatable magnetic memory disks and the metal actuator are electrically isolated from the metallic mainframe of the disk drive and the magnetic heads on the metallic actuator, the coils of the magnetic heads  and  the  magnetic  memory  disks  are  maintained  at electrical potential levels which are sufficiently close to prevent arcing therebetween and which is different from the potential of the main frame.  Electrical isolation is achieved by electrically insulating the disk spindle on which the disks are  journaled  from  the  mainframe  and  by  electrically insulating the metal actuator from the metal actuator support when the metal actuator support is attached directly to the main frame, or by electrically insulating the metal actuator support from the main frame.   An electrical potential is applied to the disks via the disk spindle and to the body of the magnetic heads via the metal actuator arm to provide potential levels which among these parts are sufficiently close to prevent arcing.

Title: Compact magnetometer probe and an array of them covering the whole human skull for measurement of magnetic fields arising from the activity of the brain
Inventor: KNUUTILA JUKKA ERKKI TAPANI
IPC: H01L39/22
Filed: 1991-12-10
Granted: 2003-03-11
Abstract: The invention relates to a sensor element made of thin film components and fiber glass, and a support structure made of fiber glass; when the sensor elements are at-tached to the support structure, a sensor system suitable for magnetoencephalographic measurements is formed.      A substrate containing a planar signal coil and a SQUID is attached on a circuit board made of fiber glass using a spring cut on the edge of the body plate. On the sensor element, there is a small but mechanically stable con-nector or several such connectors (5); when the sensor element is plugged in the receptacles (6) on the support structure (7), the element settles in a well defined orien-tation. The support structure (7) is made of a fiber glass shell following the shape of the bottom (10) dewar ves-sel, adapted to the shape of the head. The receptacles (6) are attached to the glass fiber shell by means of springs (9) made of thin fiber glass plate in such a way that an array covering the whole skull as evenly as possible is formed when the sensor elements are plugged to the re-ceptacles. The spring is cut in a way to enable rotation only around an arbitrary axis in the plane of the spring and a translation only in a direction perpendicular to the plane of the spring. When this support structure is inserted in the dewar, the individual sensor elements lean against the dewar bottom (10) by aid of three feet (11), pressed by springs (9), settling perpendicularly to the normal of the dewar bottom passing through the center of the sensor element.

Title: Formulations for oral administration, in particular to ruminants
Inventor: GREISSINGER DIETER
IPC: A23K40/35
Filed: 1992-01-14
Granted: 2002-04-30
Abstract: A formulation for oral administration, in particular to ruminants. Effective substances such as nutrients and medications should be released after a delay or slowly after they have been administered orally. In particular in the case of ruminants, very little or none should be released in the rumen. Suitable coatings are costly and, in particular, are unsuitable for administration in large quantities. Known coatings of this kind also entail the disadvantage of physiological incompatibility and/or are not permitted under current legislation. The new coating contains thinner zones and/or nominal break points that accelerate release compared to essentially even coatings. It is preferred that sharp-edged particles, such as pellets, be coated, when the coating is so configured that it can break away along the edges after oral administration. Preferred are coatings made up of two layers, the inner layer containing a filler and a film-forming medium, and the outer layer containing only film-forming medium.

Title: Snow sled
Inventor: DOLSON MURRAY
IPC: B62B13/10
Filed: 1992-01-23
Granted: 1994-11-01
Abstract: In a ride-on snow sled of the steerable type, a pair of support side runners are fixedly attached to fore and aft vertically oriented legs.  The legs are adapted to slide up and down within hollow tubular frame members.  The upper ends of the front legs of each runner are attached to one another by a non-compressible and non-extendible cable member.  Similarly, the rear pair of legs are connected through a rear tubular frame.  Thus, a shift of weight causing the right ski to extend downwardly from the frame causes a proportional lift or rise in the left ski such that the legs on the left ski retract into the frame. With the skis at different heights proportionate to the slope of the hill, an edging effect is created, permitting the operator to traverse the hill without sliding in much the same manner as a skier traverses a hill.

Title: Thermocouple assembly
Inventor: USHER JOHN D
IPC: G01K7/02
Filed: 1992-01-23
Granted: 1996-04-09
Abstract: The specification describes a thermocouple assembly for sensing temperatures of molten metals in a metallurgical vessel,  such as a tundish used in continuous steel casting. The  thermocouple  assembly  includes  a double bore  insulator containing  the  two  noble  metal  alloy  lead  wires  of  the thermocouple.  Platinum-rhodium alloys are preferred.  The weld bead joining the ends of the leads is positioned within one of the bores of the insulator such that a lower purity alloy lead is exposed in the loop.   The loop resides in a blind bore formed in the end of the double bore insulator and is enclosed in a containment zone by a refractory plug or foil disc closing off the end of the blind bore.   The double bore insulator is received in an axial bore of a refractory sheath having a closed end adjacent the loop area of the thermocouple.   The bores  of  the  double  bore  insulator  and  refractory  sheath communicate with the atmosphere to permit oxygen to diffuse therealong to the loop area to protect the platinum alloy from reaction with carbon and silica which may be present in trace amounts.          A sacrificial getter of high platinum content is also preferably positioned between the thermocouple loop and the closed end of the refractory sheath to further protect the lower purity platinum alloy loop  from chemical  attack.   A closed end molybdenum sheath having an axial bore receives the refractory  sheath therein.    High  purity  alumina  powder  is preferably packed around an upper annular space between the bore of the molybdenum sheath and refractory sheath to prevent diffusion of atmospheric oxygen within the molybdenum bore and thereby minimize the formation of gaseous molybdenum oxide at molten steel temperatures.

Patent CA-2071403-C (CA)
Inventor: VUKOVICH WILLIAM JOSEPH
IPC: B60W10/04
Filed: 1992-06-17
Granted: 1995-12-19
Abstract: An improved adaptive transmission pressure control in which cumulative adaptive corrections are stored in a multi-cell memory array, the cells being associated with specified contiguous ranges of a vehicle operating parameter, such as engine throttle position.  Periodically determined adaptive correction amounts are applied to a selected cell which includes the engine throttle setting measured at the initiation of the shift and to two or more cells associated with contiguous engine throttle ranges.  In this way, a relatively large number of cells may be employed to minimize approximation errors, while maintaining a cell-to-cell continuum of pressure correction values. In operation, an electro-hydraulic pressure regulator is controlled as a combined function of a predefined pressure command obtained from a normal table look-up and a cumulative correction amount obtained from the memory array.
