Title: Microsoudeuse de fils utile pour la connexion boule de fil isole et procede d'utilisation correspondant
Inventor: LYN ROBERT J
IPC: H01L23/49
Filed: 2002-11-19
Abstract: La présente invention concerne une microsoudeuse de fils utile pour souder un fil isolé (100) sur une surface (110). La microsoudeuse comprend une tête (106, 114) de soudure ayant une position de soudure adjacente à ladite surface (100) et une position de préparation du fil qui est distante de ladite surface (110). Un porte-conducteur (106) est situé sur la tête (106, 114) de soudure, le porte-conducteur (106) étant dimensionné et configuré pour permettre à une extrémité libre du fil isolé (100) de traverser le porte-conducteur (106) et de dépasser de ce dernier lorsque la tête (106, 114) de soudure se trouve dans la position éloignée. Une source (102) de fil isolé (100) pour ladite tête (106, 114) de soudure est prévue ainsi qu'une rallonge (112) électrique positionnée adjacente à ladite tête (106, 114) de soudure lorsque la tête (106, 114) de soudure se trouve dans la position éloignée. La rallonge (112) envoie suffisamment d'électricité au niveau de l'extrémité libre (104) sortie du fil isolé (100) pour former une boule de soudure sur l'extrémité libre. Une masse (124) associée au fil isolé (100) est prévue, ladite masse (124) étant dimensionnée et positionnée pour conduire l'énergie électrique loin du fil (100) soudé isolé afin d'empêcher la détérioration de l'isolant du fil soudé, qui se trouve loin de son extrémité libre (104).

Title: Hydro-planetary power division system
Inventor: MAYFIELD ALFRED B
IPC: B60K17/348
Filed: 1989-11-14
Abstract: HYDRO-PLANETARY POWER DIVISION SYSTEM          Abstract of the Invention A system for dividing rotary power to two or more output shafts includes planetary cluster cages that are associated with the output shafts and which are interconnected by a hydraulic circuit.  In instances where the output shafts rotate at speeds different from one another, a portion of the power from the source is directed through the hydraulic circuit to cause rotation of spiders carrying plane-tary gears within the cluster cages coupling the output shafts to a primary driveshaft.   The power division system is modular in nature in that the hydro-planetary cluster cages and associated drive axles can be easily added or deleted as desired.

Title: Probe-correlated viewing of anatomical image data
Inventor: GREENBERG MICHAEL M
IPC: A61B34/20
Filed: 1989-11-21
Abstract: A computerized system for viewing of internal anatomical regions of a patient based on previously acquired image data of the patient.   The anatomical regions are viewed in direct relationship to a moving probe which can be hand-held.   The location of the probe relative to the patient is reported to computer.  The computer then uses the previously acquired image data to generate a desired view of the patient's anatomy in relationship to the position or orientation of the probe.  An operator is able to visualize normally invisible anatomical features  before  commencing,  and  during,  procedure.    The correspondence between positions of the patient's anatomy is to locations on the stored data images is determined through an initialization procedure which can be repeated or refined between viewing  operations.    The  system  may  be  employed  during diagnostic, therapeutic, or surgical procedures.

Title: Segmented induction skull melting crucible and method
Inventor: DIEHM RANDALL S
IPC: F27B14/10
Filed: 1990-04-19
Abstract: SEGMENTED INDUCTION SKULL MELTING CRUCIBLE AND METHOD           Abstract of The Invention The crucible includes an upstanding sidewall formed of a plurality of internally cooled, metal segments arranged in side-by side relation to form a crucible chamber for receiving the metal to be melted.          The segments are separated from one another by longitudinal gaps that communicate on the inside with the crucible chamber and extend outwardly to the exterior of the sidewall.  The gaps are free of packing material that could constitute a potential source of melt contamination and are so sized in a width dimension where the gap and the chamber communicate as to substantially prevent penetration of molten metal into the gaps when the metal charge is initially melted in the crucible chamber prior to the development of a solidified metal skull.  Upper portions of the crucible segments are restrained against outward spreading during use to provide a crucible durable enough for use in production melting applications.  The crucible eliminates the need for a CaF2 type lining (skull) and for intersegment refractory packing material, thereby improving melt cleanliness.
